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 …
Breeding Bird Communities Associated With Tallgrass Prairies In Southeast Nebraska, Stephen L. Winter, Samuel D. Fuhlendorf, Britt L. Smith
Breeding Bird Communities Associated With Tallgrass Prairies In Southeast Nebraska, Stephen L. Winter, Samuel D. Fuhlendorf, Britt L. Smith
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
We collected data on bird communities associated with tallgrass prairies in two areas of southeast Nebraska that have been identified for focused conservation action: the Sandstone Prairies Biologically Unique Landscape (BUL) and the Southeast Prairies BUL. Our research was conducted in June and July of 2010 and 2011 at 14 privately–owned and state–owned properties located in Gage, Jefferson, Johnson, and Pawnee Counties (Nebraska). We detected a total of 1,108 individuals representing 41 species during 10–minute point counts with 400–m radii. The most commonly encountered species, in descending order of relative abundance (individuals detected per point count) were brown–headed cowbird, dickcissel, …
Greater Prairie-Chicken Nest Success And Habitat Selection In Southeastern Nebraska, Ty W. Matthews, Andrew J. Tyre, J. Scott Taylor, Jeffrey J. Lusk, Larkin A. Powell
Greater Prairie-Chicken Nest Success And Habitat Selection In Southeastern Nebraska, Ty W. Matthews, Andrew J. Tyre, J. Scott Taylor, Jeffrey J. Lusk, Larkin A. Powell
School of Natural Resources: Faculty Publications
Greater prairie-chickens (Tympanuchus cupido pinnatus) are reported to benefit from grasslands created through the Conservation Reserve Program (CRP). Prairie-chicken population size increased noticeably in southeastern Nebraska after >15% of county-level landscapes were converted to CRP grasslands. But, the mechanisms behind the increase in population size are not well understood, and managers and policy makers could benefit from evidence of CRP’s relative contribution to populations of prairie-chickens. Therefore, our objectives were to characterize the relations of vegetation structure and composition with prairie-chicken nest-site selection and nest survival rates at both the macrohabitat (within landscape of study site) and microhabitat …
Loggerhead Shrike (Lanius Ludovicianus): Species Conservation Assessment, Melissa J. Panella
Loggerhead Shrike (Lanius Ludovicianus): 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 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 …
The Relationship Between Ocean-Climate Indices And Diet Of Rhinoceros Auklets (Cerorhinca Monocerata) , Christine Anderson
The Relationship Between Ocean-Climate Indices And Diet Of Rhinoceros Auklets (Cerorhinca Monocerata) , Christine Anderson
Summer Research
Marine system productivity varies as a result of changing ocean-climate indices and cascade through trophic levels, impacting marine mammals and birds. Rhinoceros Auklets (Cerorhinca monocerata) are nesting seabirds in the North Pacific and can indicate variation in marine conditions via diet composition. I will analyze the relationship of Rhinoceros Auklet diets and ocean-climate indices by comparing diet composition and diversity on two islands in differing marine systems. I will also use oceanographic indices to evaluate any correlations between ocean-climate effects and diet variability in populations, providing insights into what physical forcing mechanisms may affect diet, and ultimately reproductive performance, of …
