Review Of Conspecific Attraction And Area Sensitivity Of Grassland Birds, David R.W. Bruinsma, Nicola Koper Oct 2012

Review Of Conspecific Attraction And Area Sensitivity Of Grassland Birds, David R.W. Bruinsma, Nicola Koper

Great Plains Research: A Journal of Natural and Social Sciences

Many species of grassland birds are area sensitive, which may exacerbate the ecological effects of the extensive loss and fragmentation of grasslands that has taken place across the northern Great Plains. However, the reasons for this area sensitivity are unclear, as vegetation structure, matrix composition, and restriction of movements among patches do not seem to provide viable explanations for species native to grasslands. Con specific attraction, whereby species are behaviorally stimulated to select habitat or establish territories near individuals of the same species, may help explain this area sensitivity. We review and discuss theoretical and empirical research on avian conspecific …


Review Of Birds Of Southwestern Nebraska: An Annotated Check-List Of Species In The North And South Platte River Valleys And At Lake Mcconaughy. By Mary Bomberger Brown, Stephen J. Dinsmore, And Charles R. Brown., Wayne Mollhoff Oct 2012

Review Of Birds Of Southwestern Nebraska: An Annotated Check-List Of Species In The North And South Platte River Valleys And At Lake Mcconaughy. By Mary Bomberger Brown, Stephen J. Dinsmore, And Charles R. Brown., Wayne Mollhoff

Great Plains Research: A Journal of Natural and Social Sciences

Opening with a map of the region under study, Birds of Southwestern Nebraska proceeds, in its introduction, to a summary of the presettlement landscape and a description of the large-scale habitat changes occurring since then, along with avian responses to those changes. While crediting previous avian studies in southwestern Nebraska, often not readily available to the public, the authors note this area initially received little attention from ornithologists, who tended to focus on other biologically unique parts of the state, such as the Sandhills, forests, and Pine Ridge. The body of the book consists of a list of species reported …


Channel Width And Least Tern And Piping Plover Nesting Incidence On The Lower Platte River, Nebraska, Joel G. Jorgensen, Mary Bomberger Brown, Andrew J. Tyre Apr 2012

Channel Width And Least Tern And Piping Plover Nesting Incidence On The Lower Platte River, Nebraska, Joel G. Jorgensen, Mary Bomberger Brown, Andrew J. Tyre

Great Plains Research: A Journal of Natural and Social Sciences

Endangered interior least terns (Sternula antillarum athalassos) and threatened northern Great Plains piping plovers (Charadrius melodus) nest together on midstream sandbars in large rivers in the interior of North America. We investigated the relationship between river channel width and tern and plover nesting incidence on the lower Platte River, Nebraska, using a model-based logistic regression analysis. Multiple channel width measurements and a long-term nesting data set were used in the analysis. Nesting incidence was positively associated with increasing river channel width proximal to the nesting site. At a greater distance, up to 802 m away from …


Wetland Hydrodynamics And Long-Term Use Of Spring Migration Areas By Lesser Scaup In Eastern South Dakota, Sharon N. Kahara, Steven R. Chipps Apr 2012

Wetland Hydrodynamics And Long-Term Use Of Spring Migration Areas By Lesser Scaup In Eastern South Dakota, Sharon N. Kahara, Steven R. Chipps

Great Plains Research: A Journal of Natural and Social Sciences

Lesser scaup (Aythya affinis [Eyton]) populations remain below their long-term average despite improved habitat conditions along spring migration routes and at breeding grounds. Scaup are typically associated with large, semipermanent wetlands and exhibit regional preferences along migration routes. Identifying consistently used habitats for conservation and restoration is complicated by irregular wetland availability due to the dynamic climate. We modeled long-term wetland use by lesser scaup in eastern South Dakota based on surveys conducted during below-average (1987-1989) and above-average (1993-2002) water condition years. Wetland permanence, longitude, and physiographic region were all significant determinants of use (P < 0.01). Long-term use was best described by a quadratic equation including wetland surface area variability, an index of wetland hydrodynamics that is linked to productivity, biodiversity, and value to waterfowl. Contrary to previous findings, our study shows that over the long term, lesser scaup are more than twice as likely to use permanent wetlands as they are semipermanent wetlands. The northern region of South Dakota's Prairie Coteau, which holds the highest density of hydrologically dynamic permanent wetlands, should be considered an area of conservation concern for lesser scaup. The criteria we identified may be used to identify important lesser scaup habitats in other regions of the Prairie Pothole Region.


Review Of Sandhill And Whooping Cranes: Ancient Voices Over America's Wetlands. By Paul A. Johnsgard., Janice M. Hughes Oct 2011

Review Of Sandhill And Whooping Cranes: Ancient Voices Over America's Wetlands. By Paul A. Johnsgard., Janice M. Hughes

Great Plains Research: A Journal of Natural and Social Sciences

This charming, informative book has clearly been written by someone who truly understands and appreciates the magnificence of cranes. Indeed, Sandhill and Whooping Cranes: Ancient Voices over America's Wetlands is Paul Johnsgard's fourth book on the subject. The knowledge he imparts, presented from the heart, culminates almost five decades of personal observations and research on cranes. Moreover, the book features many attractive illustrations and detailed maps sketched by the author himself.

Sandhill and Whooping Cranes is a scholarly work with a much-welcomed personal touch. Whether its reader is contemplating a pilgrimage to observe these wonderful birds in the wild, or …


Review Of Rare: Portraits Of America's Endangered Species. By Joel Sartore., Jim Mason Oct 2011

Review Of Rare: Portraits Of America's Endangered Species. By Joel Sartore., Jim Mason

Great Plains Research: A Journal of Natural and Social Sciences

Short of being in the presence of a creature, a really good photograph of one can also make a lasting impression. That is something RARE does compellingly, with exquisite portrait photos of 68 North American species that are dwindling dangerously in numbers or have recently recovered from the brink of extinction. Included are such Great Plains natives as the lesser prairie chicken, the interior least tern, and the black-footed ferret. All creatures were photographed with either a pure white or black background, but unconventional poses surprise the reader with each turn of the page, while creative framing and layout engage …


Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen Apr 2011

Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen

Great Plains Research: A Journal of Natural and Social Sciences

Over the past century, the interactions between agricultural land use and government cropland retirement programs have affected pheasant population change. Two government land retirement programs that returned croplands to grasslands, Soil Bank in the 1960s and the current Conservation Reserve Program (CRP), help to illustrate these connections. From 2007 to 2010, South Dakota lost 41% of its CRP lands and experienced an 18% decline in pheasants per mile. However, because of where CRP expirations have occurred and where pheasant populations are found, some regional variability is seen. Western South Dakota (Region 1) had an 80% increase in pheasants per mile …


Review Of Raptors Of New Mexico. Edited By Jean-Luc E. Cartron., Brian Millsap Apr 2011

Review Of Raptors Of New Mexico. Edited By Jean-Luc E. Cartron., Brian Millsap

Great Plains Research: A Journal of Natural and Social Sciences

As a raptor specialist, I eagerly look forward to the publication of state and regional books on birds of prey, typically rich with hard-to-find locally flavored information on distribution and biology. With the publication of Raptors of New Mexico, my home state has joined the ranks of the handful of states blessed with such volumes, and in fine form. This is an impressive work both in size and content, but the first thing anyone will notice are the photographs-hundreds, most top-notch, many capturing moods, scenes, and places unique to New Mexican raptors. In many ways the book is a showcase …


Review Of Whooping Crane: Images From The Wild. By Klaus Nigge., Paul Johnsgard Apr 2011

Review Of Whooping Crane: Images From The Wild. By Klaus Nigge., Paul Johnsgard

Great Plains Research: A Journal of Natural and Social Sciences

When asked to review this book I hadn't yet heard of it or its author, a wildlife photographer well known in his native Germany and the author of four photographic books published there, so I was eager to read it. The book is visually impressive, measuring 11" x 12", making it a true coffee-table production. Inside is a well-written 2S-page "primer" on whooping cranes by Krista Schlyer dealing with cranes in myth and legend, crane vocalizations and displays, and breeding biology. She also provides a brief survey of the whooping crane's population history, its near brush with extinction, and the …
