Rapid Wound Repair in the Ctenophore Mnemiopsis spp.
(2010-11-04)
The ability to quickly and efficiently close a wound is an integral part of any organism’s ability to survive. Marine organisms are exposed to numerous environmental pressures that demand the need for a rapid repair ...
Redescription and Morphometric Analysis of Isorineloricaria (Siluriformes:Loricariidae)
(2010-12-13)
In this study, the genus Isorineloricaria Isbrücker 1980 is resurrected and redescribed. The complex history of the genus is reviewed. Isorineloricaria is diagnosed from Hypostomus by an elongated caudle peduncle, elongate ...
Regulation of the p62 promoter by oxidative damage in neurodegenerative disease and aging
(2009-06-30)
Oxidative stress is regarded as the damage to a biological system caused by reactive oxygen species (ROS) when the prooxidant overwhelms the antioxidant defense and repair ability. Growing evidence reveals that oxidative ...
Relationships between benthic macroinvertebrate assemblages and the physical environment in sandy SE streams, with emphasis on stream geomorphology, hydrology and watershed disturbance
(2016-05-05)
Biodiversity is predicted to decline over the next 100 years, and stream ecosystems are
predicted to be impacted by landuse change. This predicted decline highlights the need to
understand sand-bed streams and biotic ...
Reproductive Biology of Relict Trillium (Trillium reliquum)
(2006-08-15)
Pollination and seed dispersal were studied in six populations of the endangered plant species Trillium reliquum in Bullock and Lee counties in Alabama and in Muscogee County, Georgia. Few populations of this species exist ...
Repurposing FDA Approved Drugs to Antagonize Pregnane X Receptor Mediated Chemoresistance
(2019-12-05)
Human pregnane X receptor (hPXR) is an orphan nuclear receptor that regulates key drug metabolism enzymes (DMEs) and drug-transport proteins (DTPs), including Cytochrome p450 3A4 (CYP3A4) and multidrug resistance protein ...
Response of Aquatic Biota to Changing Land Use Pattern in Streams of West Georgia, USA
(2008-05-15)
Watershed land use change is one of the most pervasive influences facing streams in the southeastern United States. In particular, watershed urbanization has a potentially dramatic impact on stream biota. Through direct ...
Revealing Hidden Diversity in a Unique Island Ecosystem: The Evolution, Ecology and Conservation of Anchialine Shrimp in the Pacific Basin
(2012-09-27)
Due to varying anthropogenic pressures, there is an urgency to accelerate research into unique island environments and their biota before they are lost forever. For many islands, one of the most threatened ecosystems may ...
Rising Tropospheric Ozone Impacts on Pathogen Resistant Pepper (Capsicum annuum)
(2024-04-26)
The increase of anthropogenic emissions has led to rising of global surface temperatures, as well
as increases in secondary greenhouse gas pollutants. A particularly dangerous secondary
pollutant is tropospheric ozone, ...
Role of Arabidopsis Thaliana Calmodulin Isoforms in Tolerance to Abiotic Stress
(2008-08-15)
Calmodulin and Ca2+ have been implicated in adaptation of plants to changes in its environment. Arabidopsis thaliana (Arabidopsis) genome has nine genetic loci encoding calmodulin protein isoforms. We have used wild type ...
The role of host sea anemones in the cleaning mutualism between anemoneshrimp and client fishes
(2010-11-11)
Cleaning symbioses may strongly impact the diversity of coral reef fishes, but little is known about the dynamics of mutualistic networks involving cleaner shrimps that form obligate associations with sea anemones. I used ...
The role of perennial hayfields in retaining predators
(2023-07-27)
The United States has seen significant native grassland loss, with over 99% decline due
to land use conversion to agriculture and industrialization, leading to declines in organisms that
utilize grasslands. This is ...
The Role of SCARECROW-LIKE 3 in Salt Tolerance During Germination and Seedling Development in Arabidopsis thaliana
(2010-07-20)
Salinity is a stress factor that results in reduced crop productivity. As much as three hectares of arable land is lost due to salinity per minute. With an increasing world population and shrinking arable land, world crop ...
The role of Ubiquinone Synthesis Complex in bc1 complex assembly of Saccharomyces cerevisiae
(2013-12-04)
Mitochondria are dynamic organelles bounded by double-membranes found in eukaryotic cells carrying various critical cellular processes. Energy generation is arguably the most important of its functions. The Electron Transport ...
The Roles of Cytokinins and Cytokinin-N-Glucosides in Development and Gene Expression of Arabidopsis thaliana
(2020-07-02)
The phytohormone cytokinin (CK) was first discovered over sixty years ago, and the decades following have produced an enormous amount of data about the various roles CK plays in intracellular signaling, gene expression, ...
Roosting behavior and habitat dynamics of male Indiana bats (Myotis sodalis) following a large-scale natural disturbance
(2005-08-15)
Indiana bats (Myotis sodalis) have been the subject of numerous ecological studies, partly because they are endangered. A majority of research has focused on maternity colonies and relatively less is known about males. ...
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 ...
