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

Studies of genetic variation within and between species can provide insights into their evolutionary history as well as important information for conserving biodiversity. An understanding of population processes can assist in the conservation of biodiversity by contrasting current versus historical patterns, and the processes that have generated these patterns. Genetic differentiation often coincides with significant geological or climatic changes that have shaped the sizes and locations of the species geographic range and altered the connectivity between populations over time. Phylogenetic and population genetic analyses can also provide a statistical framework for the investigation of how human processes such as habitat …

Understanding the role of green space in urban—suburban landscapes is becoming critical for bird conservation because of rampant habitat loss and conversion. Although not natural habitat, golf courses could play a role in bird conservation if they support breeding populations of some native species, yet scientists remain skeptical. In 2003–2009, we measured reproduction of Eastern Bluebirds (Siala sialis) in Virginia on golf courses and surrounding reference habitats, of the type that would have been present had golf courses not been developed on these sites (e.g., recreational parks, cemeteries, agriculture land, and college campus). We monitored >650 nest boxes …
Botteri's Sparrow (Peucaea Botterii) Occurs In Northern Coahuila, Mexico, Paul Van Els, Ricardo Canales-Del-Castillo, John Klicka
Botteri's Sparrow (Peucaea Botterii) Occurs In Northern Coahuila, Mexico, Paul Van Els, Ricardo Canales-Del-Castillo, John Klicka
Ornithology Program (HRC)
Botteri’s Sparrow (Peucaea botterii) occurs widely in the shrub-grasslands of southern North America. We report a breeding population of the species in the Sierra de la Encantada of northern Coahuila, Mexico, ~80 km from the Big Bend area of Texas and >300 km from the nearest previously known breeding range in southern Coahuila and central Chihuahua. We captured three individuals, which show a mostly gray dorsal coloration, suggestive of the texana subspecies, occurring from southern Texas to northern Veracruz. The exact affinity of the northern Coahuila population still needs to be ascertained. The presence of Botteri’s Sparrow in northern Coahuila …

Background
Earth history events such as climate change are believed to have played a major role in shaping patterns of genetic structure and diversity in species. However, there is a lag between the time of historical events and the collection of present-day samples that are used to infer contemporary population structure. During this lag phase contemporary processes such as dispersal or non-random mating can erase or reinforce population differences generated by historical events. In this study we evaluate the role of both historical and contemporary processes on the phylogeography of a widespread North American songbird, the Northern Cardinal, Cardinalis cardinalis …

A Phylogeographic And Population Genetic Analysis Of A Widespread, Sedentary North American Bird: The Hairy Woodpecker (Picoides Villosus), John Klicka, Garth M. Spellman, Kevin Winker, Vivien Chua, Brian T. Smith
A Phylogeographic And Population Genetic Analysis Of A Widespread, Sedentary North American Bird: The Hairy Woodpecker (Picoides Villosus), John Klicka, Garth M. Spellman, Kevin Winker, Vivien Chua, Brian T. Smith
Ornithology Program (HRC)
The Hairy Woodpecker (Picoides villosus) has one of the broadest breeding distributions of any North American bird and is also one of the most morphologically variable with as many as 21 described subspecies. This wide distribution and high degree of phenotypic diversity suggests the presence of underlying genetic structure. We used ND2 sequence from 296 individuals from 89 localities throughout the Hairy Woodpecker distribution to address this question and to explore this species’ evolutionary history. Phylogenetic analyses identified three main Hairy Woodpecker clades, each ~1.5% divergent from one another. One clade was comprised of birds from boreal and eastern zones …
