Three federal wildlife refuge complexes on the upper Texas coast include portions of the Columbia Bottomlands and other forests that are important for migratory birds and possibly bats: Texas Mid-Coast, Trinity River, and Chenier Plain.
Knowing where migratory birds consistently stop to rest and forage is critical for conservation planning, particularly along the northern and western Gulf where there is increased interest in energy development.
The USGS Southeast Regional Office has funded a cross-center collaboration between the Wetland and Aquatic Research Center and the Texas Water Science Center for the development of the Gulf of Mexico Water Dashboard. The objective of this effort is to expand the Texas Water Dashboard platform to include the coastal regions of the five Gulf states: Texas, Louisiana, Mississippi, Alabama, and...
The Team's research is organized into two major themes: 1) applied statistical methods and tools, which includes fatality estimation software; and 2) effects of wind energy development on wildlife, particularly bats.

Research in our laboratory centers on the ecology and biogeochemistry of forest ecosystems, as well as grassland and riparian systems. We examine how factors such as natural and human disturbances, climate and climate change, succession, and soil fertility shape ecosystem biogeochemistry - and the reciprocal effect of biogeochemical cycles on these and other factors.
The focus of our research is on the restoration and monitoring of the plants and soils of the Intermountain West. Our lab is part of the Snake River Field Station, but is located in Corvallis, Oregon. Research topics include fire rehabilitation effects and effectiveness, indicators of rangeland health, invasive species ecology, and restoration of shrub steppe ecosystems.
In 1995 and 1996, wolves were reintroduced into the Northern Rockies where they have since established and spread. Within Yellowstone National Park, one of the core protected release sites, the unmanaged population steadily increased to high densities, producing a large wolf population susceptible to infections such as canine parvovirus (CPV), canine distemper virus (CDV) and sarcoptic mange...
Over the past 20 years, chronic wasting disease (CWD) in Wyoming has been spreading slowly outward from the southeastern corner of the state toward the Greater Yellowstone Area and Wyoming's elk feed grounds, where more than 24,000 elk are supplementally fed each winter.
Bighorn sheep populations are often impacted by outbreaks of pneumonia that are suspected to come from domestic sheep and goats.
Researchers at the USGS are working on developing new quantitative methods to study disease dynamics in wildlife systems as well as systems at the wildlife-domestic-human interface. Much of our work focuses on how host population structure affects disease invasion, persistence and control in wildlife disease systems. We tackle these issues with a combination of simulation and statistical...

The first description of oarfish Regalecus glesne (Regalecus russellii Cuvier 1816) ageing structures
Despite being a large, conspicuous teleost with a worldwide tropical and temperate distribution, the giant oarﬁsh Regalecus spp. remain very rare ﬁsh species in terms of scientiﬁc sampling. Subsequently, very little biological information is known about Regalecus spp. and almost nothing has been concluded in the ﬁeld of age and growth (Roberts,...Midway, S.R.; Wagner, Tyler
A replacement name for Asthenes wyatti perijanus Phelps 1977
A recent near-complete phylogeny of the avian family Furnariidae (Derryberry et al. 2011) found a number of discrepancies between the phylogeny and the then-current taxonomy of the group, and several changes were proposed to reconcile the taxonomy of the family with the phylogeny. Among these was the merging of the genus Schizoeaca Cabanis 1873...Chesser, R. Terry
