Effects of temperature and energy use on fish passage and spawning success of American shad

American Shad (Alosa sapidissima) are the most numerous and economically important anadromous species on the east coast of the United States. Yet in many river systems their populations have experienced declines, primarily due to the impacts of dams and habitat loss (Limburg and Waldman 2009). Although fish passage facilities have been constructed to mitigate the impacts of dams, many of these have not provided adequate passage success for self-sustaining populations or populations at levels that meet management goals. The negative impacts of fish passage facilities may be exacerbated by high temperature late in the migratory period (Castro-Santos and Letcher 2010), a phenomenon that is likely to become worse with...

FY 2015 Northeast Region SSP/QRP Request for Proposals

Evaluation of representative bird species' Landscape Capability models developed by the Designing Sustainable Landscapes project in the 13-state, northeastern region of the United States.

The University of Massachusetts Designing Sustainable Landscapes (DSL) project (http://www.umass.edu/landeco/research/dsl/dsl.html) is evaluating the capability of the landscape in the North Atlantic-Landscape Conservation Cooperative region to sustain wildlife populations under alternative climate change and urban growth scenarios. The project has developed Landscape Capability models (LC) for representative species, integrating climate niche models, habitat capability models, and prevalence models to assess the sustainability of the representative species in the 13 northeastern states under future landscape conditions. Modeled species were selected to be representative of habitat needs and ecosystem functions...

Post-hibernation Emergence of the Northern Long-eared Bat (Myotis septentrionalis) in Virginia: Movements and Day-roost Use

With the onset and spread of White-nose Syndrome (WNS) in the eastern United States, several formerly common bat species are now threatened with widespread regional extirpation. For example, the northern long-eared bat has shown precipitous declines and reproduction in surviving bats appears curtailed suggesting functional extirpation in some areas (Francl et al. 2012). This species has been proposed for Federal listing as endangered with the final determination scheduled for April 2015 (Federal Register § 78:61045-61080). Primarily, the species is associated with deciduous forests from New England through the mid-South and Midwest. In addition, to species facing recent declines, WNS has reduced populations of species...
