Caterpillars
and Parasitoids of the Eastern
Andes
Principal Investigators:
Harold Greeney (Yanayacu)
Tom Walla (Mesa State
College)
Lee Dyer (Tulane
University)

This project is one of the longest on-going
projects atYanayacu. The goal of the research is to
collect and raise caterpillars in order to find out
what they eat, what species of adult butterfly they
become, and what parasites attack them. On the left
is a picture of the catepillar rearing
shed.

Sociality and Spatial Distribution:
social spiders as a case study
Principal Investigator:
Jessica Purcell (Univ.of British
Columbia)
|
|
|
Jessica's research is dedicated to
understanding the effect of social behavior on
spatial distribution and population dynamics on
several spatial scales. She uses social spiders
(genus Anelosimus) as a model
organism,because they exhibit a range of social
behaviors.
|
Jessica hopes to determine a) why social
and subsocial species ranges usually do not
overlap, and b) how species with different social
strategies are distributed within their
environment.
