Vernal Pool Caddisflies, Amphibian Egg Masses, and Fairy Shrimp

Research Questions: What is the distribution of caddisflies, fairy shrimp, and amphibian species in vernal pools in the Northeast? How will their distribution change as the climate warms?

Why this matters

Vernal pools contribute to healthy forest ecosystems. The species that rely on vernal pools are are an important part of the forest food web. But where and when can we find them? As climate changes, bringing changes in snow and rainfall patterns and temperature, where might we find them in the future?
