David Lewis co-authors paper on use of satellite imaging to evaluate soil parameters under dense vegetation of coastal wetlands
David Lewis co-authored a paper demonstrating the capabilities of remote satellite imaging in determining the soil parameters in areas densely covered with coastal vegetation. The authors investigated soil properties indicative of soil functions such as nutrient and organic matter turnover and storage. Their results demonstrate that remote-sensing spectral models can successfully predict soil properties indicative of ecosystem nutrient and organic matter turnover and storage, and do so in areas with dense canopy cover. Read about their study here.

Edward Haller co-authors study on chronic effects of ischemic stroke on the microvasculature of the brain
In the first ultrastructural study to demonstrate widespread damage to the microvascular system of the ipsilateral and contralateral sides of the brain in a chronic ischemic stroke model, researchers from the USF Center of Excellence for Aging and Brain Repair and the Department of Integrative Biology collaborated in a study on stroke-damaged rat brains. The unique finding of this study is that damage was observed to components of the brain-blood barrier on both sides of the brain in stroke animals at 30 days post-ischemic stroke in regions distant from the initial area of ischemia. These findings suggest persistent and/or continued BBB damage in chronic ischemia. Read about their findings here.
Valerie (Jody) Harwood publishes research documenting parallel rain runoff behavior between poultry fecal contamination and Staph aureus bacteria
Using a rainfall simulator and vegetative strips, Valerie (Jody) Harwood joined two other researchers in demonstrating that fecal contamination from poultry was transported in runoff in a similar manner to Staphylococcus aureus, Escherichia coli and Enterococcus spp. bacteria. They used a microbial source tracking (MST) marker for poultry feces/litter (the 16S rRNA gene of Brevibacterium sp. LA35 [LA35] measured by quantitative PCR) and compared this marker with fecal bacteria flushed out in their experimental system. You can read about their findings here.
Rohr research group publishes article on amphibian resistance to chytrid fungus in the journal Nature
In a continuation of their research into the effects of the chytrid fungus (Batrachochytrium dendrobatidis) on frogs, the Rohr lab, led by senior author Taegan McMahon, working with several outside investigators, discovered that 3 species of frogs can acquire behavioral or immunological resistance to the deadly fungus. Their studies showed that frogs learned to avoid the fungus after just one exposure and temperature-induced clearance. Read more about their study, published in Nature, here.

Pauline Wanjugi and Valerie (Jody) Harwood co-author a paper on enteric bacterial motility and its effect on bacterial survival in water and sediment environments
Survival of enteric bacteria in aquatic habitats varies depending upon species, strain, and environmental pressures. Mechanisms governing their fate are poorly understood. Authors Pauline Wanjugi and Valerie (Jody) Harwood compare the survival of two motile pathogens of fecal origin by culturing Escherichia coli O157 and Salmonella enterica Typhimurium. Each species has a motile and non-motile counterpart and were cultured in out-door microcosms with protozoan predators (Tetrahymena pyriformis) present or absent. Bacteria were studied in both water and sediment environments. Read more about their study here.
Lauren VanMaurik co-authors a paper on the setal morphology of the commercially important freshwater shrimp Macrobrachium rosenbergii
Using scanning electron microscopy, authors Jennifer Wortham (Univ. of Tampa, Tampa, FL), Lauren VanMaurik (USF Integrative Biology), and W. Wayne Price (Univ. of Tampa, Tampa, FL) examined the setal structures and their arrangement on the grooming appendages and sensory structures of the commercially important shrimp, Macrobrachium rosenbergii. Three male morphotypes and the female shrimp are described in the paper, accompanied with SEM photography of the setae. A literature review of terminology related to the structure of setae and setal types in decapod crustaceans is offered as the usage of various terms is ambiguous and conﬂicting in the literature. Read more about their study here.
Courtney Coon, Amber Brace and Lynn (Marty) Martin co-author a paper on the coping abilities of introduced and native congeners dealing with parasitic infections
Hosts manage parasitic infections using an array of tactics that develop with time and exposure of generations of a species to the parasite. The authors explore whether coping ability of congeners that differ in host-parasite coevolutionary history differed in response to experimental infections with a coccidian parasite. Using non-native (invasive) house sparrows and native gray-headed sparrows, the authors expose both groups of birds to the parasite, and measured physiological and biochemical responses of the birds to the infection. Read more about their study here.
