Chadron, NE, United States

Chadron State College is a four-year public college in the Nebraska State College System in Chadron, Nebraska, United States. The college is located in the northern part of the Nebraska Panhandle, in the Pine Ridge area.The school opened in June 1911, although a previous institution dated from the late 19th century. The college has an enrollment of about 3,000 students. Five of its 25 major buildings are listed in the National Register of Historic Places. Wikipedia.

Adult Cicindela nebraskana Casey were captured and allowed to mate and oviposit in the laboratory. The resultant larvae provide the first formal description for all instars of this species. In 2008 and 2009, C. nebraskana was found at several new locations in Nebraska as well as in a previously unrecorded county (Dawes). Observations were made on its habitat preference, seasonality, and behavior. © 2010 BioOne All rights reserved. Source

Nonexpert citizen groups are being used to monitor species to track ecosystem changes; however, challenges remain for proper identification, especially among diverse groups such as beetles. Tiger beetles, Cicindela spp., have been used for biological diversity monitoring because of their diversity and the ease of recognition. The finding of an apparent hybrid zone among Cicindela denverensis Casey, Cicindela limbalis Klug, and Cicindela splendida Hentz in central Nebraska prompted a detailed study of the biogeography of this species group within Nebraska, a test of characteristics that could be used by citizen scientists, and limited breeding experiments. This study suggests that while C. denverensis appears to hybridize with both C. limbalis and C. splendida within the hybrid zone, all three species maintain their integrity across most of their ranges, largely occupy unique geographic regions, and at least C. denverensis and C. splendida cooccur in many areas with no evidence of hybridization. Evidence of hybridization between C. limbalis and C. splendida was found at only two sites. Furthermore, breeding experiments with virgin C. splendida and C. denverensis showed that they are capable of producing hybrid larvae in the laboratory. The presence of morphological intergrades serves as a cautionary note when using biological indicator species. © Copyright 2012 Mathew L. Brust et al. Source

A series of field studies examined the effectiveness of using a grass blade/stem to extract tiger beetle larvae (Coleoptera: Carabidae: Cicindelinae) from their burrows without damaging the larva or the burrow a procedure often called fishing. We found that larvae of many species can be efficiently sampled at rates equal to or exceeding other methods. Extracted larvae have a low percentage of injury and can be assessed for parasitism and condition. They can be returned to either their own burrow or an alternative burrow where they can be re-sampled. The results of these studies indicate that fishing for tiger beetle larvae can be an effective tool for monitoring populations where larvae can be returned to existing burrows. In addition, the fishing technique allows for relocation of organisms while eliminating the impacts associated with excavating threatened species or larvae from rare habitats. © 2010 BioOne All rights reserved.

Surveys for the American burying beetle, Nicrophorus americanus Olivier (Silphidae), between 2001 and 2010 in Nebraska resulted in 11 new county records for this endangered species and 465 new county records for 14 other silphid species. A total of 5,212 American burying beetles were captured in more than 1,500 different locations. Using mark-recapture data, we estimated the population size of the American burying beetle (ABB) for six counties in the Sandhills. Blaine County (2003) had the largest population, with an estimated 56 ABBs per km 2 (1,338 ± 272 ABBs). The remaining estimates were between 2 and 36 ABBs per km 2, which were calculated for Loup (2010) and Holt (2010) Counties, respectively. We calculated movement distances, finding that some American burying beetles moved as far as 7.24 km in a single night. This new information greatly contributes to efforts to conserve the American burying beetle in the Great Plains and provides knowledge about other silphid species distributions, which may play a role in recovery of the American burying beetle. © 2011 Copyright by the Center for Great Plains Studies, University of Nebraska-Lincoln.

In the first decades of the twentieth century, populations of North American bison increased following the creation of several government herds while economic demand for bison decreased. Early preservationists believed that the animals would never return to a position of economic value, and those few individuals attempting to profit from the species found limited markets for their product. The experience of Custer State Park in South Dakota blurs the distinctions between profit and preservation as the managers of that herd attempted to generate revenue from their bison, first through live sales and later by slaughtering some animals for meat. Limited demand for buffalo meat as an exotic addition to Christmas dinners continued, but by the 1930s mainstream economic demand for bison all but disappeared. Faced with growing buffalo populations, federal government officials created tribal herds on the Crow and Pine Ridge reservations. The entry of the United States into World War II resulted in a domestic rationing of meat that led to the expansion of operations at Custer State Park and the elimination of the Pine Ridge tribal herd. The story of bison's recovery in the first half of the twentieth century shows that environmental factors and economic considerations of animal preservation are far from antagonistic; they are inseparable. © 2012 The Author.
