Importance of understanding landscape biases in USGS gage locations: Implications and solutions for managers Importance of understanding landscape biases in USGS gage locations: Implications and solutions for managers
Flow and water temperature are fundamental properties of stream ecosystems upon which many freshwater resource management decisions are based. U.S. Geological Survey (USGS) gages are the most important source of streamflow and water temperature data available nationwide, but the degree to which gages represent landscape attributes of the larger population of streams has not been...

Understanding how lake populations of arctic char are structured and function with special consideration of the potential effects of climate change: A multi-faceted approach. Understanding how lake populations of arctic char are structured and function with special consideration of the potential effects of climate change: A multi-faceted approach.
Size dimorphism in fish populations, both its causes and consequences, has been an area of considerable focus; however, uncertainty remains whether size dimorphism is dynamic or stabilizing and about the role of exogenous factors. Here, we explored patterns among empirical vital rates, population structure, abundance and trend, and predicted the effects of climate change on populations...

Characterization of microsatellite loci from two-spotted octopus Octopus bimaculatus Verrill 1883 from pyrosequencing reads Characterization of microsatellite loci from two-spotted octopus Octopus bimaculatus Verrill 1883 from pyrosequencing reads
We characterized 22 novel microsatellite loci in the two-spotted octopus Octopus bimaculatus using 454 pyrosequencing reads. All loci were polymorphic and will be used in studies of marine connectivity aimed at increasing sustainability of the resource. The mean number alleles per locus was 13.09 (range 7–19) and observed heterozygosities ranged from 0.50 to 1.00. Four loci pairs were...

Growth and survival of Apache Trout under static and fluctuating temperature regimes Growth and survival of Apache Trout under static and fluctuating temperature regimes
Increasing stream temperatures have important implications for arid-region fishes. Little is known about effects of high water temperatures that fluctuate over extended periods on Apache Trout Oncorhynchus gilae apache, a federally threatened species of southwestern USA streams. We compared survival and growth of juvenile Apache Trout held for 30 d in static temperatures (16, 19, 22, 25...

Making decisions in complex landscapes: Headwater stream management across multiple federal agencies Making decisions in complex landscapes: Headwater stream management across multiple federal agencies
Headwater stream ecosystems are vulnerable to numerous threats associated with climate and land use change. In the northeastern US, many headwater stream species (e.g., brook trout and stream salamanders) are of special conservation concern and may be vulnerable to climate change influences, such as changes in stream temperature and streamflow. Federal land management agencies (e.g., US...

Genetic diversity and demography of two endangered captive pronghorn subspecies from the Sonoran Desert Genetic diversity and demography of two endangered captive pronghorn subspecies from the Sonoran Desert
Species that have experienced population reduction provide valuable case studies for understanding genetic responses to demographic change. Pronghorn (Antilocapra americana) were once widespread across the North American plains but were subject to drastic population reductions due to overexploitation and habitat fragmentation during the late 19th and early 20th centuries. A. a...

Tree growth and recruitment in a leveed floodplain forest in the Mississippi River Alluvial Valley, USA Tree growth and recruitment in a leveed floodplain forest in the Mississippi River Alluvial Valley, USA
Flooding is a defining disturbance in floodplain forests affecting seed germination, seedling establishment, and tree growth. Globally, flood control, including artificial levees, dams, and channelization has altered flood regimes in floodplains. However, a paucity of data are available in regards to the long-term effects of levees on stand establishment and tree growth in floodplain...

Surveillance and monitoring of white-tailed deer for chronic wasting disease in the northeastern United States Surveillance and monitoring of white-tailed deer for chronic wasting disease in the northeastern United States
Chronic wasting disease (CWD) is a prion disease that affects both wild and captive cervid populations. In the past 45 y, CWD has spread from northern Colorado to all bordering states, as well as the midwestern United States (Midwest) and northeastern United States (Northeast), Canada, and South Korea. Because CWD is a relatively new issue for wildlife management agencies in the...

Health assessments of brown pelican (Pelecanus occidentalis) nestlings from colonies in South Carolina and Georgia, U.S.A. Health assessments of brown pelican (Pelecanus occidentalis) nestlings from colonies in South Carolina and Georgia, U.S.A.
Health evaluations of brown pelican (Pelecanus occidentalis) nestlings from three colonies along the Atlantic coast of the southeastern United States were performed in 2005, 2007, and 2008. The primary objective of this study was to establish baseline data for hematologic, biochemical, and serologic values from a relatively healthy population of free-living pelicans during early chick...
