Structure and assembly of avian communities associated with black-tailed prairie dog ecosystems.
(2007)
It is clear that even in their current remnant state, black-tailed prairie dogs continue to play a significant role in the assembly of ecological communities across the Great Plains. Conservation of prairie dogs goes well ...
A multiscale analysis of nest-site choice, nest success, and population abundance in the scissor-tailed flycatcher (Tyrannus forficatus).
(2000)
I used BBS data and habitat maps to examine associations of landscape structure and composition with the relative mean abundance of the scissor-tailed flycatcher. Routes were scattered over most of the breeding range. ...
Genetic studies in a demographic framework: Annual variation, inbreeding history, and effects of isolation in a rare group of amphibians.
(2004)
Rana sevosa had significantly lower genetic variation than non-isolated populations of its sister taxa. In fact, the isolated population had an observed heterozygosity that was 72% and allelic richness that was 61% of the ...
Cottonmouth (Agkistrodon piscivorus) spatial ecology.
(2005)
Radio-telemetry was used to study spatial ecology of a Cottonmouth (Agkistrodon piscivorus) population in eastern Texas. I examined effects of sex, reproductive state, and body size on spatial use within a riparian habitat. ...
Effects of fish density, identity, and species richness on stream ecosystems.
(2005)
Stream ecosystem properties and functions are important because they provide services such as water purification, oxygen production, and carbon fixation that help sustain life. Aquatic organisms can affect these properties ...
