DIRECTOR'S COMMENT

ITEC emerged from its second field season with many accomplishments. Participation of students, faculty and researchers in ITEC programs increased three-fold over the previous season and many programs were enlarged or enhanced. Among these include an expanded education program offering more courses and sessions, enlarged turtle conservation program with greater local participation, and expanded community education and service effort that included seminars, conservation activities and reforestation projects.

Next year ITEC programs will be broadened even more with the addition of winter break courses in December and January. Additional faculty have joined ITEC too, including Drs. Bradley Bennett (plant ecology, Florida International University), Lisa Gould (primates, University of Victoria, BC), Thomas R. Jones (herpetology, Grand Canyon University) and Joanna C. Lambert (primates, Southwest Missouri State University). We warmly welcome these individuals into our growing organization. For the first time ITEC will also be offering a Spanish-language course in Tropical Ecology and Conservation taught by Dr. James Roper.

ITEC's poster and web site for 1999-2000 have undergone major makeovers. An outstanding poster was created by ITEC's Cathy Murray which features a background scene of students conducting a forest structure group project overlaid by several photos of scenes and animals from Panamá. ITEC's web master, Mark Tway, has made significant improvements to our website including the addition of many new photographs (see article below).

The program for next season is shaping up and we are excited to have yet another chance to spend the summer in Bocas del Toro!

1998 SUMMER FIELD COURSE PROGRAM AT BOCAS DEL TORO A SMASHING SUCCESS

Five different courses in four subjects were presented at the Bocas del Toro Biological Station during the summer of 1998. Dr. Al Beulig of New College, University of South Florida, presented his Coral Reef Ecology course for the second time. The students dove on several area reefs including Bird Island, Soropta and others, but research projects concentrated on the Drago reef, a mere 30 meters from the station. One student project examined the tendency in brittle stars to use a "lead" arm. At a highly significant level, brittle stars were found to lead with a specific arm even after the arm was detached. Dr. Beulig remained at the station during the July session and with his field assistant, Mey Akasha, conducted research on sedimentation rates along the reef.

For the first time a course on Central American Geology was presented by Dr. Steve Phillips of the University of British Columbia. Dr. Phillips has spent many years conducting research in the Boca del Drago area, and knows the geology of this region better than anyone. Steve's course began with the geotectonic history of Lower Central America and concentrated on fundamentals of conducting field geology. Field trips were made to many areas in the region including one along the new road being built between Chiriqui Grande and Almirante on the mainland. The fresh road cuts along this road afforded the opportunity to study and compare mainland and insular geologic features.

Tropical Rainforest Ecology was presented in June and August by Dr. Peter Lahanas of ITEC. His courses made use of several field sites including those on Islas Colon, Bastimentos, Cristobal and on the mainland. Student research projects were quite varied, ranging from ethnobotany to the effect of electromagnetic radiation on frog embryos. The latter study, conducted by Ian Wichlacz of New College, University of South Florida, provided dramatic evidence of the harmful effect of electromagnetic radiation on developing red-eyed treefrog embryos. When subjected to three hours of radiation (supplied by an ordinary TV), there was 100% mortality as compared to 100% hatch rate in control embryos from the same clutch. Ian plans to submit this research for publication later this year.
Another first at Bocas del Toro Biological Station was the course, Primate Ecology, presented by Dr. Michelle Sauther of the University of Colorado. This energetic course spent nearly every morning monitoring movements and studying behavior of monkeys, primarily white face capuchins and howlers near the station. Student projects ranged from mapping primate movement patterns and home ranges to studies on food availability. One of the students looked at handedness in howlers and will be applying her findings to a comparison of zoo howlers and also issues of cognition. Dr. Sauther will return to the Bocas del Toro Biological Station next June to present her course again.
 

CHANGES MADE TO ITEC WEBSITE

In addition to updating website text for 1999-2000, ITEC'S web master, Mark Tway, has dramatically improved our website to reflect changes in information and technology. Now each page consists of two panels, one that scrolls to display information, and another that contains our logo and remains stationary. At each link, a message prompts the visitor that there is a photo slide show available in the stationary panel. The photos relate to each specific link topic and the slide show can be "run" at anytime and anywhere within that link. Approximately 50 new photos have been included and cover everything from course subjects, field station life, and after-course trips.

Another major change involves the placement of linkage buttons. Rather than being located at the bottom of each section, they now appear continuously in their own panel along the bottom of the screen. This greatly facilitates movement from one section to another.

One of the more enjoyable changes are the hidden mini motion-loops that Mark has included in various places on the site. For example, if you click on Mimbitimbi from the map of Bocas del Toro, a motion-loop will show a student doing back flips into Mimbitimbi creek inside Mimbitimbi Cave. Mark has also placed a counter on the site and we are currently receiving more than 100 hits per week.

1998 Research Projects

GIS/GPS TECHNOLOGY PUTS BOCAS DEL TORO BIOLOGICAL STATION ON MAP

Tom Lyman of GeoResearch, Michael-Baker Corporation, brought the latest GIS and GPS technology to Bocas del Toro Biological Station. After setting up a base station and correcting for intentional error built into GPS, Tom used GIS programming on his laptop to plot the exact locations of all the buildings at the station as well as the roads and forest patches between the station and town. Data gathered here was then superimposed on an existing topographic map of the area to produce a much more detailed and useful map for the station. Initial stages of grant submission have been made to use this technology next year to help determine the extent of deforestation among the islands of the archipelago.

MEDICAL ENTOMOLOGIST CONDUCTS STUDY ON INSECT VAMPIRES

Dr. John L. Petersen from Panamá Canal College spent several weeks conducting surveys on three of our least favorite insect groups, mosquitoes, no-seeums and sandflies. Dr. Petersen's specialty, the phlebotamine sandfly, was of particular interest and he spent long hours deep in the buttresses of forest trees collecting these insects. While at the station, he presented a lecture about his research on sandflies, complete with live examples of these rare insects. Although mosquitoes and phlebotamine sandflies can be the vectors of two human diseases, malaria and leishmaniasis, neither are known from Bocas del Toro Archipelago. No-seeums (Cuculoides) do not transmit diseases but are a nuisance. Unfortunately, not much can be done about them short of radical habitat modification. Dr. Petersen also participated in on-going ITEC courses and aided students on several entomology projects including insect field techniques, identification, and ecology. Based on his experience at Bocas, Dr. Petersen will present a paper at the Entomological Society of America meeting in Las Vegas this Fall. His talk is entitled: "Teaching Entomology in Panamá." and centers on education programs presented in Panamá.

PRELIMINARY BIRD AND PLANT SURVEYS INITIATED AT DRAGO

Dr. James Roper, who was between appointments with the Organization for Tropical Studies, Duke University, and the Universidad Federal do Paraná in Brazil, spent two weeks at the station examining the bird fauna and doing demonstrations of bird mistnetting. Dr. Roper was particularly interested in the three-wattled bellbird's occurrence in the Bocas del Toro Archipelago and the abundance of golden-collared manakins. Manakins appear to be super abundant on Isla Bastimentos where 12 separate leks were discovered on a small forest knoll only 12 m across. These colorful, lekking birds occur on all the larger islands of the archipelago and Jim became interested in the microgeographic differences in lekking behavior among populations isolated on separate islands. Jim will return to Bocas during the summer of 1999 to present his Spanish-language course in Tropical Ecology and Conservation.

Kevin Akers of the Uniformed Services University, Health Sciences Dept. spent several weeks at the station conducting surveys of birds. Kevin identified 61 species of birds at the station, including several species not currently listed there, including the Great Poto and Bat Falcon. When added to previous lists, the station count rose to 122 species. Species lists are available from ITEC on request.
Two plant biologists spent several weeks at the Bocas del Toro Biological Station conducting initial plant surveys and participating in field courses. Dr. Jennifer Lyman of Rocky Mountain College visited the station in June with her husband, Tom Lyman. She conducted surveys in station forests and along the road between the station and town of Bocas del Toro. Marianne Akers of Panamá City, also spent several weeks at the station in August collecting plants. Marianne has worked with STRI (Smithsonian Tropical Research Institute) for many years and is an expert on the flora of Panamá. Her collections were dried on our station's gas-operated dryer and will be deposited in the STRI herbarium in Panamá City.

SEDIMENTATION RATES ON BOCA DEL DRAGO CORAL REEF

Coral reef ecologist, Dr. Al Beulig of New College, University of South Florida, remained at the station after presenting his course in June to conduct a study on sedimentation rates at the Boca del Drago coral reef. This project was assisted by Mey Akasha and was directed at how sedimentation rates varied along the reef. The degree of sedimentation was found to vary on a west-to-east transect with the greatest amount of sedimentation occurring at the more exposed, eastern end. The sediment load in the water was correlated with two weather conditions, high wind and heavy rain, but the sources of the sediments differed. High winds caused re-suspension of sediments already present on the reef whereas heavy rains brought a sediment plume from the mouth of the Changuinola River into the Boca del Drago inlet. Dr. Beulig is presenting his results to the Society for Integrative and Comparative Biology in Denver, Colorado, in January.

GEOGRAPHIC POLYMORPHISM IN THE STRAWBERRY DART-POISON FROG

One of the more fascinating phenomena present in the Bocas del Toro Archipelago is the remarkable degree of color polymorphism found in the strawberry dart-poison frog, Dendrobates pumilio. Dr. Peter N. Lahanas initiated a study which examines geographic patterns of polymorphism in the region, both on islands and their adjacent mainland areas. Dr. Lahanas' study this year concentrated on Islas Colon, Solarte and Bastimentos where 24 field sites were examined. Field trips were also made to Islas Cristobal, Cayo de Agua, Escudo de Veraguas and the Valiente Peninsula, as well as mainland areas near Almirante and Chiriqui Grande. On Isla Bastimentos, Peter discovered that only frogs with a red ground color (monomorphic) were found south of the area known as Short Cut or Red Frog, but highly polymorphic populations with many different ground colors were found to the north. This narrow, low-lying stretch of land rises only about 10 ft. above sea level and divides Bastimentos into two parts, a very hilly, small northern section (about 1/8 of the island) and a larger, less hilly southern section (about 7/8 of the island).

The degree of color polymorphism displayed by frogs north of this zone was truly astounding. In some populations, frog colors varied from light blue or green, to white, yellow, orange, brown, red or combinations of all these colors! As Peter described it, "In a space of a few square meters we encountered bluish, white, yellow, orange and red frogs all hopping about like little animated jewels on the forest floor". He believes that when sea levels were higher than they are today, the northern and southern populations were isolated from each other and evolved independently. Subjected to population bottlenecks resulting from island inundation, these small, isolated populations underwent random genetic drift creating two basic color morphs: red to the south and white to the north. When sea levels receded, the two allopatric populations reunited and interbred. "What we are seeing today is the result of a net northward movement of 'red genes' from the much larger southern population which is essentially swamping out the 'white genes' to the north. The entire area of Bastimentos north of the Short Cut represents an area of intergradation".
Next year Dr. Lahanas will expand the research to include other islands in the archipelago. He also wishes to thank Lea Paddock, Robin Miller, Sammy Sanchez and Oscar Gaslin for their assistance in conducting the field work.

ITEC TURTLE PROGRAM SUFFERS SETBACKS THEN CHARGES AHEAD

Leatherbacks, Dermochelys coriacea, frequently nest on beaches throughout the Bocas del Toro Archipelago. Despite two setbacks to the program, the 1998 turtle project continued on schedule. Our first setback was brought about by coordinator, Jennifer Richard's untimely accident. On her way to the airport, Jennifer, ITEC's project director, slipped on the front porch of her parent's home and broke a bone in her knee. Because surgery would be required over the next several months, Jennifer could not join the turtle crew.

As a consequence, Mark Tway was called upon to take Jennifer's place and effectively ran the program from early June to August. Mark was a TRE student in 1997 and has been an integral part of ITEC ever since. In addition to his volunteering for the turtle coordinating position, he doubles as ITEC webmaster. His work on our website has been recognized by many as outstanding. Mark was joined this summer by his wife, Maria, and by a host of research assistants including Mary Hart, Angela Mattison, Sophia Shirline, Lisa Shender, Sergio Camberos, Seth Cloues, Mey Akasha, Robin Miller, and Kelly Samek. Local naturalists, Oscar Gaslin and Sammy Sanchez also joined our crew and donated the use of their cayucas for trips to Islas Bastimentos and Cristobal.

The other setback resulted from our exclusion from Bluff Beach where many turtles come to nest. ANAM (formerly INRENARE), provided us with permits to monitor all beaches in the archipelago but without explanation excluded Bluff Beach. ITEC volunteers spent most of their time monitoring nesting activity on Changuinola Beach north of the archipelago, and on First, Second, Third and Long Beaches on Isla Basitmentos. Among other findings, it was determined that hawksbills were nesting in slightly greater numbers than in 1997. This probably represents a random oscillation in numbers from year to year, and is not an indication of reduced poaching. Poaching of sea turtles in the region remains a constant threat to these endangered animals (see "Slaughtered Leatherbacks ..." below). Now, with the exclusion of Bluff Beach, there will remain a "hole" in the data being accumulated for the area. Hopefully by next season this situation will be remedied. This year, ITEC has submitted several grant proposals for funding our marine turtle project next year. The 1997 and 1998 ITEC marine turtle project technical reports are available on request.

SLAUGHTERED LEATHERBACKS LITTER CHANGUINOLA BEACH


Personnel in the marine turtle program met with a grisly sight on their first trip to Changuinola Beach this year. Acting on a tip from local Drago resident, Sammy Sanchez, that leatherbacks were being poached on Changuinola Beach, the turtle crew went to see first-hand. Eighteen leatherback carcasses were discovered within a 2 km stretch of beach just south of the Changuinola River mouth. Some of the dead turtles had been there several weeks, but others were quite recent and a poacher’s camp was found on the beach. From the physical evidence present, poachers appear to slaughter leatherbacks by first cutting the flippers off of living turtles so that they can be turned more easily onto their backs, and then the plastron is cut away to expose the entrails. After removing both shelled and oviducal (unshelled) eggs, the probably still-living female turtle is left to die a slow death on the beach. Due to the unpleasant taste of leatherback flesh, the meat is not used although folklore has it that the blood is sometimes used in rituals by local Indians.
ITEC’s Cathy Murray and Peter Lahanas examine a poached leatherback on Changuinola Beach. More than 30 dead leatherbacks were discovered on this beach.

Although this area is within the San San-Pond Sock National Preserve, there is no enforcement of national laws forbidding such activity. Between June andJuly a total of 31 leatherback carcasses were recorded on Changuinola Beach. The number of dead turtles coincided with reduced nesting along this stretch. The turtle project reported that because leatherbacks generally return to the same beach to lay eggs 7-9 times in any one season, the probability of catching all the individuals nesting in any particular year is high. Thus, by early July there were few nests recorded here while leatherback nests were still abundant on Bluff and Long Beaches in the Islands. It was calculated that about 75-80% of all the leatherbacks nesting on Changuinola Beach in 1998 were taken by poachers.

COMMUNITY SERVICE

STUDENTS AT BOCA DEL DRAGO SCHOOL RECEIVE LESSONS IN CONSERVATION AND REFORESTATION

With excerpts by Chris Wedding

For the first time a program of conservation education was presented at the rural school in Boca del Drago. This tiny two-room school with outhouse, represents the learning focal point for this small community of mostly indigenous Ngöbe Indians. Conservation education directed at native populations will reap the greatest benefits because most of the environmental degradation stems from their use of the land for subsistence farming.
Chris Wedding presented the program as part of his senior thesis at Western Kentucky University. The program was six weeks in length, and had two components, conservation education and reforestation.


CONSERVATION EDUCATION PROGRAM AT DRAGO SCHOOL

The conservation education program at Boca del Drago consisted of daily lectures, projects and activities for the students grades 3-6. Many of the activities and lectures were designed to develop respect for nature by teaching the intricacies of the sciences with the hope that this process will indirectly lead to conservation. At the end of each day, it was emphasized that students should study with their parents or tell them what they learned so as to educate other generations. A good mix of games and lecture material was used to maintain students’ attention. Quizzes proved useful to reinforce the need to study and conservation “mantras” were recited daily.

To determine what students’ attitudes were towards conservation, Chris ran a survey which asked the following questions: Do you live in the city or country? Do you live near forests, streams or lakes? Do you enjoy living near them? Why? What is good about natural environments like forests, lakes, streams, beaches, reefs and ocean? How can they benefit you? Should we preserve nature? Why? How?
In response to the survey Chris discovered that very few of the students had much to say about conservation in general, and were unclear about the concept. He then provided the students a with a list of why forests are good and should be protected. Chris taught them that forests are beneficial because they:

1) provide oxygen which we need to breathe, 2) take in carbon dioxide which helps fight the greenhouse effect, 3) clean and filter air and water, 4) prevent erosion and soil depletion, 5) provide many plants that contain medicinal properties, 6) provide shade and cooler regional temperatures, 7) provide homes for wildlife (illustrated by pointing out that animals need homes like us), 8) provide foundation for eco-tourism which brings in jobs and money, 9) provide wood for houses, 10) provide an opportunity for study, and 11) satisfy the human need for beautiful surroundings.
Chris also pointed out that reef, ocean, and lake environments are also beneficial because that they: 1) provide opportunity for tourism which brings in jobs and money, 2) provide home for amazing animals like spiny crustaceans, colorful fish, and varied turtles, and 3) satisfy our need for beauty, and of course, are fun to swim in.

Other aspects of his program included the recital of mantras, such as "Reduce, Reuse, and Recycle", or, "We will never throw trash on the ground or in the streams, lakes or ocean" and "We will do these things to preserve the beauty of Panamá". Chris says that the recitation of such mantras was helpful. "One day as we were picking up trash, a bright student smiled and repeated the 'no littering' mantra showing that she made the connection between the saying and the practice. Other activities that proved instructive were games and demonstrations that taught ecological concepts, nutrient recycling, and the causes for the different life zones present around the world. Chris also had the children decorate their classrooms with artifacts from nature. These physical artifacts, such as interesting sticks, rocks, flowers, plants added a tangible dimension to the lectures.

REFORESTATION PROJECT AT BOCA DEL DRAGO SCHOOL

With ITEC funds, Chris was able to obtain several hundred seedlings of tropical hardwood trees to be planted in the deforested area next to and behind the Boca del Drago school house. On one bright, sunny morning in August, all of the children at the school and their teachers, as well as all the members of the Tropical Rainforest Ecology course in session at the station, gathered at the school grounds for the reforestation project. Under Chris’, students, teachers and ITEC personnel divided into groups to plant the trees. Each tree was provided with a stake for support, forest leaflitter for fertilizer, and in many cases, a small covering was constructed over the seedling to protect it from the intense tropical sun. This activity was followed by a lecture by Chris on forest regeneration. The students not only got out of a morning of regular class work, but learned a great deal about forest conservation as well, and had a lot of fun in the process!

Chris Wedding, and ITEC would like to extend a special thanks to Fatima Sanchez, head teacher at Boca del Drago school, for allowing the program to be presented. Ms. Sanchez clearly understands the need for conservation in Bocas del Toro and in Panamá, and should be highly commended for her eager participation in this program.

ITEC TEACHES ENVIRONMENTAL AWARENESS AT THE BOCAS DEL TORO SCHOOL

By Lisa Shender

This July three ITEC volunteers, Sergio Camberos, Seth Cloues, and Lisa Shender, initiated an environmental education program with the 5th and 6th grade classes of the Bocas del Toro elementary school. Volunteers met with each class twice during a two-week period to provide instruction in Spanish on topics such as the water cycle, pollution and contamination, recycling, and deforestation. Classes were an hour in length and incorporated interactive educational games, poster presentations, demonstrations, and mini-lectures.

Students from local schools and ITEC personnel work to clean Sandfly Beach, Bocas del Toro. More than 100 people participated in various aspects of this effort.
For example during a session on the water cycle, kids first learned the concepts of cohesion, adhesion, and evaporation. They then played a tag game which illustrated how a drop of water falling from a rain cloud can go from a river, to a lake, to a cow, to the cow's milk, to a human body, to the ocean, and finally back into a cloud. The kids learned how pollution is introduced into the cycle (i.e. motor oil dumped from a boat into the ocean or pesticide sprays in banana plantations) and how pollution affects both the animals and people who are dependent on water.

The children were very excited (to the point of being rowdy) to participate in these activities and the teachers were very appreciative of ITEC's efforts (and probably glad to get the kids off their hands for an hour). It was a learning experience for both the children and program volunteers, and it is our hope that ITEC will continue to develop its environmental education program next summer.

MORE THAN 50 CHILDREN PARTICIPATE IN FIRST ANNUAL BEACH CLEANUP

By Lisa Shender

On July 25th, 52 children participated in a beach clean-up which was organized by program volunteers, Sergio Camberos and Lisa Shender. From 12 noon to 2:30p.m., kids collected trash on the approximately 2 km stretch of beach, collecting over 100 13-gallon bags of garbage. Forty-one local businesses donated money and refreshments, such as cookies, punch, and hot dogs for the children's enjoyment. Although participants were paid $0.25 for each bag of trash collected, ITEC emphasized that the kids were not there to earn money, but rather to clean the beach for a safer and cleaner environment for both people and animals. Because the beach clean-up was done in conjunction with the environmental education program, 5th and 6th graders were the main participants. All excess donated money ($60) was given to the elementary school for the purchase of classroom waste baskets which the school teachers greatly needed.
This group effort was a great success. Both kids and ITEC volunteers enjoyed the clean-up and the beach looked 100% better afterwards. When the beach had been cleaned, and the kids were feasting on cookies and punch, I saw a boy throw his cookie wrapper on the sand. I was frustrated that he had not seemed to learn from the day's cleaning activities. However, I was quickly reassured when I overheard a girl say to him, "What are you throwing trash for? We're trying to clean the beach!" It's obvious that one day of cleaning isn't going to change the habits that are ingrained in so many children (and adults too), but we hope the beach clean-up was a positive influence and that the kids who participated will think twice before littering the beach or elsewhere.


OTHER STATION ACTIVITIES

At the end of the June and July sessions, ITEC staff led students on a 10-day field trip that took them the length and breadth of Panamá. Participants on the trip included Maura Ambron, Katie Gogolin, Alex Head, Peter Lahanas, Carrie LaFrenz, Matt Murphy, Sandra Roig, Mark Tway, Maria Tway, Suzanne VanAtta and Jamie Vernacchio. Peter Lahanas led the first group, and Mark Tway led the second. The following story is derived from the trials and tribulations of the July trip.
The expedition began by driving ITEC's field vehicle, "Bessy" on to the ferry, Palanga, and sailing three hours to the port city of Chiriqui Grande on the opposite end of Chiriqui Bay. Plenty of time here to relax and watch the archipelago with its many mangrove islands slip by, or catch up on that novel started a month ago. From Chiriqui Grande we drove the only road out of town, southwestward and straight up the Caribbean side of the Chiriqui mountains. After stopping briefly on the continental divide at 4000 ft to take in the view of the Pacific Ocean, we proceeded back down into the much dryer Pacific versant of Panamá. Here the lush and largely intact rainforest vegetation of the Caribbean side, gives way to pastures, savannas and dryforest patches. From hot and humid David, the largest city in western Panamá, we headed back up into the cool Chiriqui mountains to the small town of Boquete nestled in a high valley at the foot of 10,000 ft Volcan Barú. Boquete, as its name implies, is a beautiful cloudforest village home to Panamá's annual flower festival. The next morning we woke early and headed to the Quetzal Trail which has its start at the end of a steep, rocky canyon. After crossing a suspension foot-bridge, we headed directly into the dripping, cool cloud forest. We have seen quetzals along this trail previously, but none were sighted on this day. Still, many other birds were recorded and the views were fantastic. The differences between this cloud forest and the lowland rain forests of Bocas del Toro are striking, especially with regard to epiphytic growth. Bromeliads, orchids, pipers, aroids, begonias, mosses, ferns and liverworts covered every square inch of trees and rocks, and brightly-colored impatience formed thick hedges along the mountain trail.

In the early afternoon we returned to David and bought a new set of tires for Bessy, which were sorely needed. From here we headed east on the Pan-American Highway towards Panamá City. After driving 50 miles or so a terrible screeching sound suddenly began emanating from the transmission. Not wanting to stop, and having nowhere to do so, we continued on, hoping to get to Panamá City where we could have it looked at and repaired. We spent the night in Santiago and the next morning drove out to Sarigua National Park. The vegetation here, tropical thorn scrub, is unlike any other in lower Central America and consists primarily of acacias and other xeric-adapted trees, several types of cacti, and bright-red latiritic soils. Surrounding a large inland bay, this area was historically an important hunting ground for pre-Colombian Indians 4000-5000 years ago. Everywhere was evidence of human occupation with artifacts, such as bone, flint points and pottery shards littering the ground. Huge shellfish middens were everywhere. Maria Tway, a graduate student at Florida State University specializing in Mayan archaeology was delighted to finally be doing something --- archaeological! At one point we discovered a large "mano" (a roller-pin-like grain-grinding tool made of stone) and joined park personnel in its excavation. This turned out to be one of the best manos found in the area and along with several interesting pottery shards found, was put on display in the park's museum. Sarigua is near the picturesque village of Parita, a Spanish settlement dating from the early 1600s. The architecture is typically Spanish with colorful adobe houses, red-tiled roofs and gated courtyards. We stopped off at the town's cathedral, a gleaming white structure with oyster-shells embedded in the bell tower. Built in 1652, this is one of the oldest churches in Panamá.

We continued east in the afternoon and just outside La Chorrera, only 40 minutes from Panamá City, Bessy's tranny finally gave out. She completely refused to go forward or backwards. So with all of us riding in the car, we were towed to a nearby mechanic's shop. We were a bit dubious at first that these shade-tree mechanics (literally, with mangos falling all around!) could do the job. Our fears were alleviated though, when in just under an hour these guys had the transmission out and torn apart. The damage was not as severe as we had feared. Three bearings and two gears were toast, but the housing was fine. Still, it would take 12 more days before it was repaired and the after-course trip continued on without poor Bessy.

Fortunately, we had very good friends in Panamá City. Student X (TRE-98-1) and her parents M and L invited us into their palatial home near Panama City. The home sits on a hill surrounded by forest, and overlooks the Panamá City skyline 10 miles away. And then there were Juma and Titi. They often take in lost, abandoned or wild animals that have no where else to go. Juma, a white-faced capuchin, and Titi, a Geoffrey's tamarin were adopted in this way. Juma was particularly entertaining. M. described him as a two year old on steroids. He was constantly getting into things and would often run off with an item to some inaccessible location and taunt the person begging for the item back. He could make up for it though, when he jumped onto your shoulder, pressed his mouth to your neck, and purred!

We used the residence as our home base while we explored the eastern end of Panamá. The next morning we took the busses to Portobelo. Portobelo was the disembarking point for gold plundered from South America and destined for Spain. A heavily armed fortress was built here made famous by visits from Henry Morgan, Sir Frances Drake, and other pirates of the Spanish Caribbean. Some of us also took advantage of the many sights that Panamá City had to offer, and visited Panamá Vieja, the Indian markets, the colonial section, the Panamá Canal and museums.

One of the highlights of our time in the canal zone was our trip to an Emberá village on the Rio Chagres. The Rio Chagres provides most of the water flow into Lake Gatun, which in turn flows north and south keeping the Panamá Canal operational. We met the Emberá chief at his dugout along the river and travel upstream about an hour to his village. There we were entertained with traditional dances, crafts, and information on Emberá culture. The Emberá are derived from the Chocoan Indians of western Colombia and are culturally and physically very different from the Ngöbe in Bocas del Toro, or the Kuna of San Blas.

The next morning we boarded our small single-engine plane for our flight to San Blas, or Kuna Yala. The Kuna are quite isolated from Panamá City and the rest of the world. No roads enter Kuna Yala and the only way to get there is by plane or boat. Although our destination, the Carti group in San Blas, is only a half hour from Panamá City, its like stepping centuries back in time. From the airstrip in Carti we took a Kuna dugout to Carti Tupile, home of our hosts, the Vallez-Smith family. As in previous years the family greeted us with much joy and quickly made us feel at home. Home in this case was a typical Kuna thatch-roofed, cane-sided sand-floored hut. The kitchen consisted of a carefully tended fire on the floor with logs radiating from the center. There is no running water; water is brought from the river daily by dugout canoe. Fresh water is used for bathing, but not cooking. For cooking, Kuna always use coconut water which imparts a coconut flavor to the staple diet of fish and plantain. The family sleeps in hammocks as did some of us. We also pitched a couple of tents for those who wanted to sleep on the ground. The Kuna are a remarkable people, both in stature and customs which they hold to very tenaciously. The average height of the Kuna is only about four and a half feet tall. The women are most remarkable with their brightly-colored traditional dress. The costume consists of a colorful mola (intricate cloth tapestry) sewed onto bright blouses, a dark patterned skirt, and a bright red and yellow scarf worn over the head. The outfit is completed with beads, called "weenees" that cover the wrists, ankles and calves, gold ear and nose rings, and a black line drawn down the nose. This costume is not worn for tourists, but is the daily dress of all Kuna women.

Our first evening we all went down to the Congress House, the largest hut in the village. This house is where the Kuna chiefs come in the evenings to hear complaints, recommendations, etc. from the community, and to make decrees. It is required that we "present" ourselves to the chief so that he knows that we are in the village. We spent the first day and evening getting to know our Kuna hosts and their village. Some of us went for a sail in a intricately-carved and decorated traditional sailing dugout. We were very lucky arriving when we did because a festival had been planned for the next evening. The festivities consisted of traditional dances, music and theatrics. The students donated a bag of candy, some of which was periodically tossed to the children bringing about delighted screams as the kids made mad dashes for the loot.

We traveled widely during our stay in San Blas. One trip took us to Dog Island which was about two hours away by dugout. This small, coconut island is a stereotypical tropical island paradise with its white sandy beaches and crystal clear aquamarine water. There was a sunken boat 20 m off shore which, along with the surrounding reef, made for spectacular snorkeling. Not long after we landed, Kuna from nearby islands came over and set up displays of molas and other crafts which they hoped we would buy. On our way back from Dog Island we stopped at another village to buy more crafts and discovered an "aquarium" dug into the ground to attract tourists. Several marine animals had been placed in the aquarium including fish, starfish, sea cucumbers, and hawksbill sea turtles. Sea turtles are protected by Panamá, and holding them in pens is illegal. But in San Blas, the Kuna have the last word. Not wanting these endangered reptiles to spend their lives here, Katie Gogolin and Sandra Roig bought two of them. The Kuna here no doubt thought we were insane when it was explained that the turtles were bought so that they could be released! We got back into our dugout and after moving a half mile off shore, the turtles were, with much pomp and circumstance, returned to the sea.

There was always something to do here and we were sad to leave our newly acquired friends. Its amazing how many friends we made and how at home we felt in only four days.

SMITHSONIAN OPENS FIELD STATION IN BOCAS DEL TORO

In July 1998, The Smithsonian Tropical Research Institute (STRI) opened a field station in the town of Bocas del Toro. Although primarily a marine research facility, STRI hopes to eventually offer courses in marine biology. The station is located on the narrow isthmus north of Bocas del Toro, and across the road from Sandfly Beach. Information about the station can be obtained from Dr. Howard S. Barnes, STRI, 011-507-5211, BarnesH@tivoli.si.edu.


NEW ITEC FIELD COURSES AND FACULTY FOR 1999-2000

WANT TO BEGIN THE NEW MILLENIUM ON A TROPICAL BEACH?


For the first time, ITEC will present courses at the Bocas del Toro Biological Station over winter break 1999-2000. Due to time constraints during the holiday break, these courses will be three weeks in length. Two courses will be offered. Dr. Joanna E. Lambert of Southwest Missouri University will present Primate Ecology. Dr. Lambert's course will focus on field exercises that teach fundamentals of conducting research on free ranging primates. Dr. Peter N. Lahanas will also present his Tropical Rainforest Ecology course during the Winter Session.

NEOTROPICAL HERPETOLOGY

Dr. Thomas R. Jones from Grand Canyon University in Phoenix, Arizona will present a field course in herpetology at the Bocas del Toro Biological Station in July, 1999. Dr. Jones received his Masters degree at Auburn University, Ph.D. at Arizona State University and did postoctoral work at the University of Michigan. He is currently department chair at GCU. Dr. Jones’ course will focus on ecology, biogeography and systematics of Neotropical amphibians and reptiles. As with all ITEC field courses, there will be a balance between lectures and field exercises and independent research projects will represent an important component.

TROPICAL PLANT ECOLOGY AND ETHNOBOTANY

Dr. Bradley Bennett of Florida International University will present his course in tropical plant ecology and ethnobotany this July at Boca del Drago. Dr. Bennett has taught a multitude of ecology and conservation courses during his career, including many field courses. His course will first focus on ecological interactions between tropical plants and their environment, and then proceed to ethonobotany. Due to the proximity of three different cultures including the indigenous Guaymí, the Bocas del Toro Archipelago represents an ideal location for the study of ethnobotany.

ITEC TO OFFER FIRST COURSE IN SPANISH

During the August session of 1999, ITEC will offer a Spanish-language course in Tropical Ecology and Conservation. This course will be taught by Dr. James Roper of the Universidad Federal do Paraná, Brazil, and is directed towards Latin Americans. The course will cover a wide array of ecological and conservation topics as they relate to Neotropical environments. As with all ITEC courses, emphasis will be placed on field work designed to teach specific techniques in field ecology that will be useful in designing and implementing research projects in the student's home countries. Conservation and sustainable development topics will round out the course and will and help provide the tools necessary for transforming research results into meaningful conservation programs and policy.

Dr. Roper has broad experience with teaching field ecology courses. He taught Tropical Field Ecology at the University of Pennsylvania from 1992 to 1995 and during 1997-1998, as a member of a three-faculty team with the Organization for Tropical Studies (OTS) in Costa Rica. His teaching duties there included Fundamentals of Tropical Biology, Tropical Environmental Sciences and Methods of Research in Tropical Biology. Dr. Roper has also taught field ethology, conservation, biology, ornithology, introductory zoology and wildlife ecology.

Dr. Roper's primary research interest focuses on ornithology and in particular, nest predation and reproductive ecology. His research and education has taken him to 14 countries in Latin America, including Panamá, Venezuela, Peru, Costa Rica, Bolivia, Argentina, Paraguay, Mexico, Belize, Guatemala, Honduras, Colombia, Ecuador, and Brasil.
