Evolution of Flowering Time in Native North American Grapevines
(2010-05-03)
Native North American grapevines represent a significant portion of the biodiversity within the genus Vitis (Vitaceae). Previous studies of taxonomy and natural history suggested patterns of biogeography, phenology and ...
Ecoimmunological Investigations of the Cottonmouth (Agkistrodon piscivorus)
(2011-08-04)
Despite the benefits gained from studying the immune system of non-traditional model organisms, including the discovery of key components of the human immune system, squamates remain the most poorly-understood major ...
GlpR Regulates the Glyoxylate Pathway and Virulence Factor Production by Pseudomonas aeruginosa
(2012-05-10)
Pseudomonas aeruginosa infections are the leading cause of morbidity and mortality for cystic fibrosis (CF) patients. P. aeruginosa establishes life-long infection in the CF lung by utilizing various adaptation strategies ...
Assessing Some Key Approaches Used to Monitor and Study Populations of Birds
(2012-01-10)
Efforts to monitor birds and determine their distributions often make assumptions that allow for inference into parameters of interest but necessitate that potentially confounding factors be ignored. In any scientific ...
Invasive Characteristics of Chinese Privet (Ligustrum sinense Lour.) in a Bay Swamp in the Fall Line Hills of East-Central Alabama
(2008-09-09)
Exotic species often become invasive because of an ability to occur in many habitat types with a variety of environmental variables. One species of plant that is particularly invasive throughout the southeastern United ...
Analysis of Stable Isotopes of Hydrogen to Determine Migrational Source of Silver-Haired Bats (Lasionycteris noctivagans) in Alabama
(2008-09-09)
Signatures of deuterium obtained from claws of 21 silver-haired bats (Lasionycteris noctivagans) were used to estimate the nearest probable pre-migratory location of these bats. For 5 consecutive weekends beginning 28 ...
Feathers at a fine scale
(2008-09-09)
In 1668, Antoine von Leeuwenhoek improved the crude microscopes that were being produced in Europe to better study small biological objects (Madigan et al. 1997). Although von Leeuwenhoek 's microscope revolutionized ...
Ecology Of Rudbeckia auriculata (Perdue) Kral (Asteraceae)
(2008-09-09)
Rudbeckia auriculata is a rare species endemic to three southeastern states: Alabama, Florida, and Georgia. Eight censuses of flowering individuals of the species were conducted from 1992 to 2002. Although the number of ...
Survival and Transmission of Selected Pathogens on Airplane Cabin Surfaces and Selection of Phages Specific for Campylobacter jejuni
(2014-04-28)
We determined the limits of survival and transmission of Escherichia coli O157:H7 and methicillin-resistant Staphylococcus aureus (MRSA) on common surfaces found in the cabin of a civil aircraft. The two pathogens were ...
Transcriptional Adaptations to Low Salinity in Euryhaline Crustaceans
(2014-05-02)
The transfer of euryhaline crustaceans from full-strength seawater to low salinity is
known to induce a myriad of physiology changes corresponding with active ion uptake across the
posterior gill pairs. The goal of this ...
