Parochlus Kiefferi (Garrett, 1925) In Nebraska (Diptera: Chironomidae), Barbara Hayford
Parochlus Kiefferi (Garrett, 1925) In Nebraska (Diptera: Chironomidae), Barbara Hayford
Great Plains Research: A Journal of Natural and Social Sciences
A rare species of nonbiting aquatic midge, Parochlus kiefferi (Garrett, 1925), was discovered in Squaw Creek in the Pine Ridge of northwest Nebraska. Parochlus is a genus of midge found throughout the Southern Hemisphere and is only represented by this one species in the Northern Hemisphere. The typical North American species distribution of P. kiefferi includes high alpine and northern latitude streams, so the collection of P. kiefferi from a low elevation and low-latitude stream in Nebraska represents a range extension for the species. A survey for P. kiefferi from 83 samples from 53 stream sites in northern Nebraska yielded …
Health And Fertility Implications Related To Seasonal Changes In Kidney Fat Index Of White-Tailed Jackrabbits In South Dakota, Dustin Schaible, Charles D. Dieter
Health And Fertility Implications Related To Seasonal Changes In Kidney Fat Index Of White-Tailed Jackrabbits In South Dakota, Dustin Schaible, Charles D. Dieter
Great Plains Research: A Journal of Natural and Social Sciences
White-tailed jackrabbit (Lepus townsendii) populations in the Northern Plains have been in a general decline for the past decade or longer. A suggested reason for this population decline was reduced body condition of individual jackrabbits due to habitat changes. In order to evaluate body condition, we determined the kidney fat index of 314 white-tailed jackrabbits harvested in 44 counties throughout South Dakota. We removed and weighed kidneys and all perirenal fat associated with the kidneys from collected jackrabbits. We measured kidney weight to determine times of high metabolic activity as indicated by an increase in mass. Body condition was …
Toward A Strategy For The Conservation And Protection Of The World’S Temperate Grasslands, William D. Henwood
Toward A Strategy For The Conservation And Protection Of The World’S Temperate Grasslands, William D. Henwood
Great Plains Research: A Journal of Natural and Social Sciences
Temperate grasslands are one of the world’s great biomes and were once home to some of the largest assemblages of wildlife the earth has ever known. Today these grasslands are considered the most altered terrestrial ecosystem on the planet and are recognized as the most endangered ecosystem on most continents. While species and habitat declines continue, temperate grasslands have the lowest level of protection of the world’s 14 biomes. With only 4% of the biome under protected status, considerable effort will be required to increase this level of protection. Several international bodies have suggested that achieving at least a 10% …
Redefining The Dust Bowl Region Via Popular Perception And Geotechnology, Jess C. Porter, G. Allen Finchum
Redefining The Dust Bowl Region Via Popular Perception And Geotechnology, Jess C. Porter, G. Allen Finchum
Great Plains Research: A Journal of Natural and Social Sciences
The Dust Bowl is a historical vernacular region that has been delimited by a diverse group of academics, literary authors, and popular cultural voices. However, the general public’s perception of the Dust Bowl region has not been mapped and analyzed. This research queried residents of 93 Great Plains counties in order to ascertain their perceptions and knowledge of the vernacular Dust Bowl region. Analysis of the responses via the application of geographic information system mapping reveals striking differences between respondents of varying age and place of residence. Findings suggest that spatial understanding of the Dust Bowl phenomena is eroding among …
