A Northward Range Extension Of The Hispid Cotton Rat (Sigmodon Hispidus) In Missouri, Cody W. Thompson, Elmer J. Finck
A Northward Range Extension Of The Hispid Cotton Rat (Sigmodon Hispidus) In Missouri, Cody W. Thompson, Elmer J. Finck
The Prairie Naturalist
The hispid cotton rat (Sigmodon hispidus) is a widely distributed rodent with a geographic range extending from north-central Mexico to southern Nebraska and central Virginia and from southeastern Arizona east to Florida (Carleton et al. 1999, Peppers and Bradley 2000, Wilson and Reeder 2005) with isolated populations in Arizona (Bradley et al. 2012) and California (Clark 1972). Range expansions for the species have been well documented (Clark 1972, Farney 1975, Benedict et al. 2000, Wright et al. 2010, Wills et al. 2011). The majority of these range expansions have occurred across the Central Plains during the 20th century …
Western Burrowing Owl (Athene Cunicularia Hypugaea): Species Conservation Assessment, Melissa J. Panella
Western Burrowing Owl (Athene Cunicularia Hypugaea): Species Conservation Assessment, Melissa J. Panella
Nebraska Game and Parks Commission: Publications
The primary goal in the development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the western subspecies of Burrowing Owl (Athene cunicularia hypugaea) as a Tier I at-risk species. Provided are some general management recommendations regarding Western Burrowing Owls (hereafter Burrowing Owls). Conservation practitioners will need to use professional judgment for specific management decisions based on objectives, location, and site-specific conditions. Based on a considerable body of literature, this particular species conservation assessment provides an …

Fringed Myotis (Myotis Thysanodes Pahasapensis): Species Conservation Assessment, Melissa J. Panella
Nebraska Game and Parks Commission: Publications
The primary goal in development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the fringed myotis (Myotis thysanodes pahasapensis) as a Tier I at-risk species. Provided are some general management recommendations regarding the fringed myotis. Conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge of the fringed myotis that will aid in the decision-making …
Inconsistent Outcomes Of Heterogeneity-Based Management Underscore Importance Of Matching Evaluation To Conservation Objectives, Devan Allen Mcgranahan, David M. Engle, Samuel D. Fuhlendorf, Stephen L. Winter, James R. Miller, Diane M. Debinski

Conservation policy often incentivizes managers of human-impacted areas to create landscape heterogeneity to maximize biodiversity. In rangeland, patchy disturbance regimes create landscape heterogeneity (patch contrast), but outcomes of heterogeneity-based management are rarely tested for a universal response. We analyzed four habitat variables—vegetation structure, plant functional group composition, litter cover, and bare ground—from five experimental rangelands in Oklahoma and Iowa, USA. We tested for response consistency to heterogeneity-based management across and within locations. We calculated effect sizes for each variable to compare patch contrast on pastures managed for heterogeneity (patch burn-grazing) and pastures managed for homogeneity (grazing with homogeneous fire regimes). …

The primary goal in the development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the Loggerhead Shrike (Lanius ludovicianus) as a Tier I at-risk species. Here, I provide some general management recommendations regarding Loggerhead Shrikes. However, conservation practitioners will need to use professional judgment for specific management decisions based on objectives, location, and site-specific conditions. This resource provides available knowledge of Loggerhead Shrikes that may aid in the decision-making process or in identifying research needs …
Birds Of The Central Platte River Valley And Adjacent Counties, Mary Bomberger Brown, Paul A. Johnsgard
Birds Of The Central Platte River Valley And Adjacent Counties, Mary Bomberger Brown, Paul A. Johnsgard
Zea E-Books Collection
The central Platte River Valley region of Nebraska is described ecologically, and defined as encompassing 11 counties and nearly 10,000 square miles, and extending about 120 miles from the western edge of Lincoln County to the eastern edge of Merrick County. At its center is the Platte River, the historic spring staging area for Sandhill and Whooping cranes, five species of geese, and millions of waterfowl and water-dependent birds, in addition to providing the breeding habitats for more than 100 other bird species. Collectively, at least 373 bird species have been reported from the Central Platte Valley, making it the …
Overwinter Mortality Of Sympatric Juvenile Bluegill And Yellow Perch In Mid-Temperate Prairie Lakes, Jeffrey C. Jolley, Mark A. Kaemingk, David W. Willis, Richard S. Holland
Overwinter Mortality Of Sympatric Juvenile Bluegill And Yellow Perch In Mid-Temperate Prairie Lakes, Jeffrey C. Jolley, Mark A. Kaemingk, David W. Willis, Richard S. Holland

Substantial mortality can occur in age-0 fish populations during their first year of life, especially in winter; this can potentially influence overall recruitment into the adult population. As such, we compared relative abundances between fall and spring catches of sympatric juvenile bluegill Lepomis macrochirus Rafinesque and yellow perch Perca flavescens (Mitchill) to evaluate the magnitude of overwinter mortality across locations (five lakes for two years) and through time (one lake for six years). In addition, we compared both quantile-quantile and increment plots, based on length-frequency histograms from fall- and spring-caught cohorts from 2004 to 2010, to determine if mortality was …
Mutation From Arginine To Lysine At The Position 189 Of Hemagglutinin Contributes To The Antigenic Drift In H3n2 Swine Influenza Viruses, Jianqiang Ye, Yifei Xu, Jillian Harris, Hailiang Sun, Andrew S. Bowman, Fred L. Cunningham, Carol Cardona, Kyoungjin J. Yoon, Richard D. Slemons, Xiu-Feng Wan

Two distinct antigenic clusters were previously identified among the H3N2 swine influenza A viruses (IAVs) and were designated H3N2SIV-alpha and H3N2SIV-beta (Feng et al., 2013. Journal of Virology 87(13), 7655–7667). A consistent mutation was observed at the position 189 of hemagglutinin (R189K) between H3N2SIV-alpha and H3N2SIV-beta fair isolates. To evaluate the contribution of R189K mutation to the antigenic drift from H3N2SIV-alpha to H3N2SIV-beta, four reassortant viruses with189R or189K were generated. The antigenic cartography demonstrated that the R189K mutation in the hemagglutinin of H3N2IAV contributed to the antigenicdrift, separating these viruses into H3N2SIV-alpha to H3N2SIV- beta. This R189K mutation was also …
