Characterization of the gut and skin microbiomes of wild-caught fishes from Lake Guntersville, Alabama
(2016-07-29)
In recent years, a paradigm shift has occurred in the area of organismal health. Where Koch and Hill’s fundamental postulates equating to “one microbe—one disease” were once regarded as the rule, research has now shifted ...
Hearing evolution across the air-water interface: lessons from comparative audiometry in turtles and salamanders
(2016-12-12)
The physical differences between water and air present unique challenges to organisms living in both environments, including challenges to the sense organs. In the auditory system, acoustic impedance mismatch is a challenge ...
Transgenic Disruption of Aromatase Using the Daughterless Construct to Alter Sex Ratio in Common Carp, Cyprinus Carpio
(2016-08-01)
The common carp (Cyprinus Carpio) is considered as invasive alien species (IAS) in North America and is particularly ecologically damaging in Australia. Traditional methods, biological means, harvesting and chemicals, used ...
Capture and Mortality Rates of Largemouth Bass at Guntersville and Wheeler Reservoirs, Alabama
(2016-06-13)
Catch-and-release angling for Largemouth Bass Micropterus salmoides has substantially increased since the 1980s, yet few studies have assessed the population-level consequences of these activities. Guntersville and Wheeler ...
Polycyclic Aromatic Hydrocarbons in Red Snapper, Lutjanus campechanus, and Sediment Samples After the Deepwater Horizon Oil Spill
(2016-01-12)
The Deepwater Horizon oil spill occurred on 20 April 2010, which led to approximately 4.9 million barrels of oil entering the northern Gulf of Mexico. Red snapper, Lutjanus campechanus, are an important species in the Gulf ...
Genome-wide association studies for columnaris resistance and morphology in hybrid catfish
(2016-03-03)
Catfish is the primary aquaculture species in the United States. Recently, the catfish industry in the USA has encountered unprecedented challenges due to increasing feed and energy costs, devastating diseases, and severe ...
Taxonomy and phylogenetics of fish blood flukes using morphology, life history, and molecular markers
(2016-08-05)
Fish blood flukes (Digenea: Aporocotylidae) are of rapidly progressing and emerging interest to ecology and evolutionary biologists because some lineages may have coevolved with the major lineages of non-tetrapod vertebrates ...
Genetic Technologies for Disease Resistance Research and Enhancement in Catfish
(2016-12-10)
A microinjection protocol was developed and validated for CRISPR/Cas9 gene editing in channel catfish, Ictalurus punctatus. This protocol proved to be rapid, efficient and does not require elaborate equipment or a high ...
Consumer adaptation mediates top-down regulation of ecosystems across a nutrient gradient
(2016-03-07)
Individuals within a species frequently differ in important traits, and these differences are known functions of genetic, epigenetic, and environmental influences. While evolutionary biologists have been studying ...
Effects of Hydrologic Change on Stream Fish Assemblages in Alabama
(2016-04-26)
Alabama is home to the most diverse aquatic fauna in the United States. A major threat to this fauna is habitat degradation mediated by hydrologic alteration. Land cover changes contribute to disrupted flow patterns and ...
