Niche model results predicting fundamentally suitable and unsuitable habitat for freshwater mussel concentrations in the Meramec Basin This layer represents fundamentally suitable and unsuitable habitat for freshwater mussels in the Meramec Basin as modeled by these authors on May 17, 2017 based on spatial data ranging from 1990 to 2014. Identification of habitat characteristics associated with the presence of freshwater mussels is challenging but crucial for the conservation of this declining fauna. Most mussel species are found in multi-species assemblages suggesting that physical factors influence presence similarly across species. In lotic environments, geomorphic and hydraulic characteristics appear to be important factors for predicting mussel presence. We used maximum entropy (MaxEnt) modeling to evaluate hydrogeomorphic variables associated...

These samples are maintained by USFWS and the feather samples in particular are part of the AviSample Network metadata repository (see Brlik et al. 2022. The reuse of avian samples: opportunities, pitfalls, and a solution. Ibis 164:343-349).Additional information for samples collected at Utqiagvik and in association with the tracking project can be found in the Utqiagvik shorebird project (file://ifw7ro-file.fws.doi.net/datamgt/mbm/mbmsh_009_Utqiagvik_shorebird_project)...

However, little is known about migratory movements and connectivity of shorebird populations. By identifying migratory stop-over and wintering areas, we can begin to identify sites that should be conserved and evaluate the relative risks of development and climate change scenarios. Beginning in 2017, we initiated a project to track the migration movements of shorebird species using Argos, GPS, and Pinpoint tags. The primary objective of this study is to collect baseline information on movement patterns of shorebirds during the post-breeding period...
