Jaw Morpho-Functional Diversity, Trophic Ecology, and Historical Biogeography of the Neotropical Suckermouth Armored Catfishes (Siluriformes, Loricariidae)
(2009-05-04)
Tropical South America is renowned for its unparalleled biodiversity. Among vertebrates, fish diversity exceeds that of any other group. Estimates of total Neotropical fish richness range between 5000 and 8000 species, of ...
United States Commerce in Live Vertebrates: Patterns and Contribution to Biological Invasions and Homogenization
(2009-05-04)
The trade in live vertebrates is a threat to biodiversity, homogenizing distinct flora and fauna, introducing invasive species and parasites, and depleting wild populations. Because records of live vertebrates imported or ...
Phylogeography and population structure of Antarctic ophiuroids: effects of life history, oceanography and paleoclimatology
(2009-07-01)
The Antarctic landmass and surrounding continental shelf have been isolated for over 24 million years. Geographic and thermal isolation have resulted in a highly endemic, diverse benthic marine fauna. This fauna has been ...
Intraspecific signaling functions of juvenal plumage
(2009-04-22)
The function and evolution of avian plumage coloration has been the subject of many studies over the past decade, but virtually all of this research has focused on the plumages of sexually mature individuals. The color ...
Systematics and evolutionary history of sea catfishes (Siluriformes: Ariidae)
(2009-04-28)
Ariids or sea catfishes are one of the two otophysan fish families (out of 67 families in four orders) that inhabit primarily marine and brackish waters, although some ariid species occur strictly in fresh waters. The ...
Isolation and Characterization of SCARECROW Suppressor Mutants in Arabidopsis thaliana
(2008-09-09)
SCARECROW (SCR) is a transcriptional regulator that plays key roles in several developmental processes in a model plant Arabidopsis thaliana. SCR orthologs have been identified in agriculturally important plants such as ...
Population Dynamic Modeling of the Corkscrew Sea Anemone Bartholomea Annulata on Caribbean Coral Reefs
(2009-02-23)
The corkscrew anemone Bartholomea annulata is a large, common sea anemone on Caribbean coral reefs. The holobiont of B. annulata, endosymbiotic microalgae (zooxanthellae), and ectosymbiotic cleaner shrimps may have positive ...
Habitat Associations Among Bats on Redstone Arsenal, Alabama
(2009-02-23)
As forests become more fragmented, more research about use of forests by bats at the landscape level is needed. I employed 2 methods to investigate use of forest by foraging bats; mist-net surveys and ultrasonic-detection ...
Ecological Associations of Bats (Mammalia: Chiroptera) in the Upper Mobile-Tensaw River Delta, Alabama
(2009-02-23)
Relatively little is known about most of the 15 species of bats in Alabama. Especially scarce are data on species occurring in southern Alabama, including the Mobile-Tensaw Delta region. Because there are significant ...
Characterization of the Glyoxylate Pathway in Pseudomonas aeruginosa
(2009-12-17)
Pseudomonas aeruginosa infections are the leading cause of lung dysfunction and mortality in Cystic Fibrosis (CF) patients. Adaptation of P. aeruginosa to become a chronic pathogen of the CF lung includes acquisition of ...
