Overview

Vernal pools in New England are a unique seasonally varying aquatic habitat that support a number of species found nowhere else. Amphibians that use vernal pools must gather to breed, lay eggs and complete larval development before the pools dry out. Invertebrates in the pools are both prey and predators for the amphibians. Stranding of eggs or larvae may occur in dry years. On the other hand if the pools fail to dry these species may be threatened by competitors, predators and diseases that may establish in permanent water. Climate and other environmental changes over time determine where and how well these pool-dependent species thrive. Their long-term persistence in New England forests depends on many factors including pool size, proximity to roads, forest disturbance and connectivity, trends in precipitation and temperature among others.

Intern Responsibilities

Participants in this observational internship will record basic pool conditions and life cycle events (metamorphosis) for Spotted Salamanders and Wood Frogs and follow the changes in invertebrate populations in three vernal pools from the onset of amphibian breeding in April to the emergence of their metamorphs in June. Weekly monitoring visits of 3-4 hours will allow enough time to become familiar with the pool ecosystem as you discover what is going on under the water and around the pools. Birds and other wildlife are frequently seen and heard. Photography (including underwater with cell phone in a pouch) is encouraged. You will be expected to share your experience with the GCC community with a poster, slide show or talk after completing the internship.
