Ecological niche modeling: integrating patterns of species richness, factors shaping geographical range limits, and conservation planning
(2009)
The concept of the niche has been a central theme of ecology for over half a century. With recent advances in Geographic Information Systems (GIS) and statistical procedures, the inferential method of ecological niche ...
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. ...
Functional morphology and diet of Late Cretaceous mammals of North America.
(2003)
Principal components analysis of tooth morphology and diet in modern mammals indicates that gross morphological differences in tooth shape can be detected within groups, as well as among groups. Tooth morphology separated ...
Cambrian [Marjuman] trilobites (Arthropoda) of the Cow Head, western Newfoundland.
(2005)
Conglomerates consisting of shelf-derived limestone boulders in debris flows form the fossiliferous strata of the Cow Head Group on the west coast of Newfoundland. These conglomerates have yielded in excess of 20,000 ...
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 ...
Phylogeography and Diversification of the Ouachita Mountain Endemic Salamanders of the
(2008)
Climatic changes associated with Pleistocene glacial cycles profoundly affected species distributions, patterns of inter-population gene flow, and demography. In species restricted to montane habitats, ranges may expand ...
Mammalian paleontology of the Monarch Mill Formation at Eastgate, Churchill County, Nevada.
(2002)
Three new species of Leptodontomys (L. korthi n. sp., L. schnelli n. sp., and L. protistopikos n. sp.) are described based on a large sample (249 specimens) of maxillae, mandibles, incisors, and isolated upper and lower ...
Endogenous opioid modulation of the neural and behavioral correlates of learning and memory necessary for infant attachment.
(2004)
Disorganized attachment in which a child attaches to an abusive caregiver is a significant risk factor for childhood and adult psychiatric disorders. Both animal and clinical studies suggest that disorganized attachment ...
Faunal composition, non-marine vertebrates, of the upper Cedar Mountain formation (Cretaceous: Albian-Cenomanian), central Utah.
(2000)
Finally, taxonomic associations were examined using correspondence analyses. Monte Carlo simulations were performed to determine which taxa were significantly abundant (or absent) at each site. Each family and most mammal ...
