It was in the winter semester 1987/1988 when I found a one-page notice on the bulletin board in the Institute for Zoology of the University of Tübingen, Germany, announcing a “Seminar of Tropical Ecology”. The seminar would culminate with a field trip to Ecuador including a maximum number of 6–8 participants, i.e., a small group of “chosen ones”. In the fourth year of my biology degree, I was instantly enthusiastic about the idea of traveling to Ecuador, although I had no idea how I would be able to afford it. Also, the competition to go would be intense. On the first day of the seminar, it was clear that all students in line at the door to the seminar room wanted to visit the country named after the equator running through it.
After the plans for the seminar and the “general conditions” for possible participation in the trip to South America had been discussed, the work of the seminar began. On the agenda were a review of literature about tropical ecology and threats to and conservation of fauna and flora, which were of particular interest to me. A central goal of the excursion to Ecuador would be to build a platform on a tall tree on which we could stay overnight and explore a rainforest canopy. Ensuring the safety of climbing techniques using ropes, seat belts, and clamps (
My literature search quickly guided me to Terry Erwin’s publications (e.g.,
Schematic drawing of Erwin’s biodegradable insecticide fogging technology from the seminar. The letters A, B, C, and D in the sketch mark rotatable fogging machines. The small squares label plastic funnels with attached vessels that are placed ca. two meters above the ground to collect falling specimens.
The plane ride of our team, the excursion leader, a mountaineer, and six other students from Frankfurt to Quito in February 1988 marked the beginning of several weeks of adventure. Those memories have remained unforgettable to this day.
Our seminar team spent one week on the west side of the Andes and four weeks in the “Oriente” of Ecuador as guests of a Quechua family in the small village of Santa Rosa de Otas, approximately 2.5 hours downstream from the small city of Misahualli. From this location on the south bank of the Napo River, we explored the typical lowland rain forest of that region. After several days we became used to the overwhelming and omnipresent green. As our eyes became more trained to our surroundings, a variety of life revealed itself, fascinating and amazing us again and again. Terry Erwin’s estimate of the total number of insect species suddenly seemed not as exaggerated as it had seemed to some. As if to underscore the plausibility of this number, no insect or spider we spotted was like the next one we would see a few moments later (Fig.
Assisted by our hosts, we assembled a platform at a height of approximately 20 meters in a large tree (Fig.
After returning from Ecuador we organized and evaluated our information. In the summer of 1988, we prepared a public exhibition at the Institute for Zoology of the University of Tübingen, Germany to present our results. We reported on our Ecuadorian “moments of fascination” in regional magazines (Fig.
More than 30 years have passed since that seminar experience. Although my subsequent professional path led me to biomedicine, Terry Erwin’s work and the experiences in Ecuador were both the starting point and source of motivation for me to continue working as an amateur entomologist to this day. As a result, I work on my collection (Fig.
I did not have the good fortune and honor to meet Terry Erwin personally, but I am grateful for all I have learnt from his work and everything I have read about him and his personality (
