Endocrine mediation of alternative mating tactics in toads: A proximate perspective on ecological patterns and sexual selection.
(2005)
Male Great Plains toads (Bufo cognatus) and Woodhouse's toads (Bufo woodhousii) alternate between one of two mating tactics; they may either vocalize to attract mates or they may adopt a non-calling "satellite" tactic. ...
Factors affecting mercury contamination in fish from Caddo Lake, Texas.
(2007)
We conducted a survey of mercury contamination in largemouth bass ( Micropterus salmoides) from Caddo Lake, Texas, and found that largemouth bass collected from forested wetland habitats had higher concentrations of mercury ...
Multiple species comparative analysis of human chromosome 22 between markers D22S1687 and D22S419 and gene expression profiling in zebrafish.
(2006)
Major large scale insertions or deletions that resulted in gene number differences between human and chimpanzee were discovered in the IGLL and LCR22s within this region, with four human insertions from 6 Kb to 75 Kb and ...
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 ...
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 ...
Adaptations for caching and robbery in two sympatric chipmunks.
(2005)
We captured least chipmunks (Tamias minimus) and eastern chipmunks (T. striatus) from co-existing populations and assessed their comparative success at heterospecific robbery in a naturalistic laboratory setting. The smaller ...
