Globally, groundwater dependent ecosystems (GDEs) are increasingly vulnerable to groundwater extraction and land use practices. 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...

This dataset provides field tagging and recapture information used to examine the movement patterns of Arkansas River Shiner Notropis girardi and Emerald Shiner Notropis atherinoides. Fish were tagged and recaptured from October 2018 to June 2020 over two field seasons. Tagged fish were collected using seine netting at seven locations in the first field season and four locations in the second field season. Once captured, all fish were anesthetized using buffered tricaine methanesulfonate before measuring and tagging. Over the first field season (2018-2019), all fish were tagged with two visible implant elastomer (VIE) tags. Arkansas River Shiner ≥ 50 mm total length were also tagged with a passive integrated transponder...

Grouse: These data on sharp-tailed grouse survival times are provided for individuals wanting to run an age-period survival analysis. Entry and exit times are expressed in integer days from the start of the study. Entry age and exit age expressed in integer days are also included. Data are structured to implement survival analysis. White-tailed Deer: These data on white-tailed deer survival times are provided for individuals wanting to run an age-period survival analysis. Entry and exit times are expressed in integer weeks from the start of the study. Entry age and exit age expressed in integer weeks are also included. Data are structured to implement survival analysis. Only adult female individuals that were chronic-wasting...

We developed and tested neural network-based models to recognize and count emigrating juvenile river herring in continuous video. 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. This data release includes four datasets that were used to test model performance and select the best fitting model. (1) The “Model Evaluation Dataset” includes count and presence/absence...

The data contained in child items of this page were developed to support the Species Status Assessments conducted by the U.S. Fish & Wildlife Service and conservation planning for State, Federal, and non-government researchers, managers, landowners, and other partners for five focal herpetofauna species: gopher tortoise (Gopherus polyphemus), southern hognose snake (Heterodon simus), Florida pine snake (Pituophis melanoleucus mugitus), gopher frog (Lithobates capito), and striped newt (Notophthalmus perstriatus). These data were developed by the USGS Cooperative Fish & Wildlife Research Unit at the University of Georgia in collaboration with other partners. The three child items contain the following data: (1)...
