Life history, diversity and patterns of bat community structure in the Spring Mountains of southern Nevada
… June 1992 through September 1994. Distributions, life history and general ecological attributes of fourteen species of bats were summarized. Thirteen species were present in low to mid elevations, ten species in mid to high elevations, and three species at all elevations. Bats were most abundant …

GENETIC POPULATION STRUCTURE AND CONSERVATION OF BULL TROUT IN THE EAST FORK BITTERROOT RIVER DRAINAGE, MONTANA
… listed as threatened by the U.S. Fish and Wildlife Service. Understanding and conserving the genetic and life history diversity of bull trout populations across their range is critical as conservation, management, and recovery plans are developed. Numerous studies in different regions have …

From genes to species: Characterizing spatial and temporal variation in frog and toad multidimensional biodiversity
Biodiversity is a complex concept encapsulating the variation that occurs within and among levels of biological organization. It is positively linked to ecosystem persistence, adaptability, and function. Biodiversity loss, driven by global change and human activities, is one of the most prominent …

The role of intrinsic and extrinsic factors in shaping alternative migratory tactics and metabolic phenotypes in brown trout
… for a considerable portion of phenotypic diversity produced in nature, and is instrumental to the structure and function of ecosystems. Understanding how, and why, intraspecific diversity persists is essential for predicting and managing the effects of global change, particularly because …

Dispersal of Fry and Distribution of Redds Interact to Shape Density Dependence in Winter Steelhead of the Skagit River
The spatial scale of dispersal during early life stages when mortality rates are high is essential for understanding the relationship of the distribution of spawners to population productivity. In this study, we quantified the fine-scale distribution of age-0+ (fry) steelhead (Oncorhynchus mykiss) …

THE LIFE HISTORY AND ECOLOGY OF RIVERINE SOCKEYE SALMON (ONCORHYNCHUS NERKA) IN A LARGE FLOODPLAIN RIVER
The productivity and life history diversity of salmonids is linked to the complexity of habitat in large floodplain rivers. Dynamic floodplain processes are driven by flow, sediment transport, cut and fill alluviation, woody plant succession, and ecosystem engineers, notably beavers, that create …

Resource use and life history patterns of juvenile Coho and Chinook salmon in an Alaskan estuary
… rearing habitats, estuaries may also bolster the life history diversity expressed in a population, thereby increasing population-level stability. Conversely, the degradation and loss of estuarine habitats has been partially responsible for declines in wild salmon populations. In Alaska, most …
