Groundwater supports these ecosystems by providing inflow, which can maintain water levels, water temperature, and chemistry necessary to sustain the biodiversity that they support. Many aquatic systems receive groundwater as a portion of base flow, and in some systems (e.g., springs, seeps, fens) the connection with groundwater is significant and important to the system’s integrity and persistence. Groundwater management decisions for human use may not consider ecological effects of those actions on GDEs, which rely on groundwater to maintain ecological function. This disconnect between...

Continuous video was collected from an underwater camera installed at Great Herring Pond in Bourne, Massachusetts (USA) between June and November 2017. Our algorithm extracts video frames to assess presence/absence of fish and count numbers of fish emigrating. We used extracted video frames to assess model performance. Provided datasets include information about extracted frames that were used for model assessment.

We designed a series of questions to link fine-scale predator movements and vulnerability of dabbling duck nests to predator encounters and egg predation. We conducted our study over a 4-year period using 41 GPS-collared raccoons and striped skunks, two of the most widespread mammalian predators of waterfowl eggs in North America, and more than 2000 monitored duck nests.

On the second night, snakes were offered dead carrion (baits) of each prey type (mouse, chicken chick) equal to 30% of their mass. Choices were monitored overnight using game cameras and then transcribed the following day.

Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations between 1069 and 1200 m above sea level that operated nightly from May 2013 through September 2013. We compared these data to data collected at similar locations during 2007-2011 to determine the response of bats to increased moth abundance during 2013.

It also includes seedling germination and survival data for a large-scale seed addition and grass removal experiment that varied both seed rain and grass cover.
