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 ...
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 ...
Seasonal Habitat and Shelter Selection by Reintroduced Eastern Indigo Snakes in Conecuh National Forest, Alabama
(2013-11-15)
Species reintroduction has become an increasingly popular conservation method for reestablishing extirpated populations of declining species. Because poor habitat quality at release sites has been one of the most frequently ...
Small RNAs in Gossypium and Their Roles in the Response to Heat Stress
(2013-12-05)
Small regulatory RNAs, which usually are 20 to 24 nt in length, play crucial roles in plant growth, development, and stress response. Based on their origin, biogenesis and function, plant small RNAs can be classified into ...
Disturbance in the anchialine ecosystem: ramifications for ecology and physiology
(2014-04-07)
Habitats in the anchialine ecosystem are defined as coastal ponds, pools, and caves that lack surface connections to the open ocean, but possess both seawater and freshwater influences due to subterranean connections to ...
The effects of dietary and skeletal calcium availability on reproductive performance of mammals
(2011-12-01)
Investment in offspring production often requires the mobilization of endogenous resources, a strategy which may negatively impact maternal condition. In mammals, skeletal ossification in growing offspring requires ...
