Evaluation of semen from nondomestic birds
Aspects of poultry Al technology are applicable to nondomestic birds. However, modifications in the methods of semen collection, evaluation, and insemination are often necessary to accommodate either the bird's size, sperm numbers, or. female anatomy. This section provides a brief overview of procedures used to evaluate semen from nondomestic birds. Unless specified, materials, reagents, etc., are

Field guide to the Mesozoic accretionary complex along Turnagain Arm and Kachemak Bay, south-central Alaska
Turnagain Arm, just east of Anchorage, provides a readily accessible, world-class cross section through a Mesozoic accretionary wedge. Nearly continuous exposures along the Seward Highway, the Alaska Railroad, and the shoreline of Turnagain Arm display the two main constituent units of the Chugach terrane: the McHugh Complex and Valdez Group. In this paper we describe seven bedrock geology stops a

Genetic variation among wild lake trout populations: the 'wanted' and the 'unwanted'
In this study we examine genetic variation within and among self-sustaining lake trout populations from the Great Lakes basin, the Rainy Lake basin, and Yellowstone Lake. We used RFLP analysis and direct sequencing to examine DNA sequence variation among several mitochondrial and nuclear genes, including highly conserved loci (e.g. cytochrome b, nuclear exon regions) and highly variable loci (e.g

Imperiled mammalian fauna of aquatic ecosystems in the Southeast: A historical perspective
About 100 species of mammals are endemic to the southeastern United States, an area of diverse habitat types and high biodiversity. Many of these species are either formally considered aquatic or semi-aquatic, or they are otherwise closely associated with aquatic ecosystems. In the southeastern United States, greater than 80 percent of mammalian species are listed in some category of concern throu

Imperiled mammalian fauna of aquatic ecosystems in the Southeast: A management perspective
Management of imperiled mammals associated with aquatic ecosystems in the southeastern United States ranges from almost no management for some species to intensive, high-profile programs for others. Aquatic mammals are notoriously difficult to census because they are often secretive, trap-wary, relatively rare, or have extensive movement patterns. As a result, conservation efforts aimed at these a
