- algal and plant responses to abiotic and/or biotic environmental pressures,
- the underlying mechanisms associated with these responses (e.g., physiological compensation), and
- how the ability to respond to environmental change [or the lack thereof] relates to the ecology of these organisms and long-term native plant community resilience.
My research group is broadly interested in understanding how organism detect, integrate and respond to environmental information. More specifically, we have been focusing on how animals use light and other environmental cues to time major seasonal transitions. We seek to understand the physiological mechanisms underlying these processes in order to be better able to predict how individuals, populations and ultimately species will or will not be able to respond to rapid global change.
His research is focused on how species interact with each other and with their environment to shape population structures and the evolution of communities. Communities of special interest include sandhills, wet pine flatwoods (e.g., long leaf pine savannas), pitcher plant bogs and those greatly affected by climate change and invasive species. Specific topics of ongoing work include gopher tortoise ecology, orchid pollination, host-plant selection by swallowtail butterflies, and the consequences of insect-vectored tree diseases.
His research interests are ecological parasitology; biology of parasitic castrators especially rhizocephalan barnacles; diversity of parasites within the Mobile-Tensaw Delta of Alabama and Ubatuba Bay in Brazil; crustacean biology; and the construction of submarines such as the H.L. Hunley in Mobile during the Civil War.Click here for more information on Jack O'Brien's research
My lab group is interested in understanding how changes in the genome modify the phenotype
and ultimately effect fitness. We use a combination of field work, lab work, and computation
to identify changes in gene sequence and regulation to understand how selection shapes
trait evolution. We use venom as our model system because of the near 1-to-1 match
from gene to toxin, high intra- and inter-specific variation, and ecological importance
in feeding and defense. Using genomic sequencing technologies and approaches, it is
possible to examine the functionality of phenotypes
down to single mutations in the genome. We take these data and places them in a meaningful ecological and evolutionary framework by accounting for variability within species across the landscape and controlling for shared evolutionary history to understand how biodiversity is generated through adaptation. To accomplish our research goals, we draw from many fields including biogeography, bioinformatics, ecological modeling, molecular genetics, phylogenetics, phylogeography, and population genetics.
His research interests lie in all areas of insect ecology and biology. Current work includes studies in community structure, biodiversity, faunistics and symbiosis. My major current research projects are as follows
Community ecology of insects: This research focuses on establishing empirical and theoretical relationships between habitat parameters and species distributions. Of particular interest is the relationship between the determinants of distribution and scale (from habitat patch to continent).
Symbiotic interactions: Parasitism, mutualism and commensalism can be view as a continuum of effects that two species experience when living in close association with one another, i.e., symbiotic interactions are dynamic. Using a trichomycetes (fungus)-larval black fly (dipteran) model, He is investigating the dynamic nature of this symbiotic association in aquatic habitats. In collaboration with Audi Byrne (University of South Alabama), models are being developed to explain this dynamic. Research also focuses on the ecology, host specificity, and faunistics of other insect symbiotes including nematodes and microsporidians.Click here for more information on John McCreadie's research
- His research interests are on taxonomy, systematics and ecology of the Agaricales (mushrooms and allies). Most of my work has focused on neotropical and subtropical fungi, particularly those from Costa Rica.
- He is working with the American Shiitake (Lentinula raphanica). An edible species like the commercial strain, this mushroom in not well-known and there are no genetic or physiology studies.
- Because of the proximity to mayor water bodies –the Mobile River Delta and the Gulf of Mexico- he is involved in a collaborative effort to document fungi associated to seagrasses.
Broadly, my group is interested in the biotic and abiotic contexts that shape the composition of ecological communities and the functioning of ecosystems. We use a combination of microcosm experiments, manipulative field experiments, and global-scale observational experiments to explore: 1) the drivers of biodiversity at local and global scales, 2) how fine-scale changes in plant-microbiomes scale to influence community interactions and ecosystem function, and 3) how global change will re-shape interactions among microbial communities, plant communities, plant microbiomes, and ecosystem function.
His research interests are rooted in the ecology and natural history of vertebrates. Specific projects focus on population ecology: geographic distribution, movements, reproduction, and conservation of reptiles and amphibians. Current research projects are as follow:
- Population ecology and conservation of the Alabama Red-bellied Turtle
- Herpetological survey of the Upper Mobile/Tensaw Delta
- Status of the Mississippi Diamondback Terrapin along coastal Alabama
- Vertebrate road-kill survey along the Mobile Bay Causeway (US90/98)
Her research is focused on understanding how microbes (bacteria in particular), both individually and as communities, respond to various contaminants. She takes two different approaches to this problem. The first involves isolating pure cultures involved in the degradation of specific chemical compounds and characterising the genes and enzymes involved in the degradation pathway. The second approach uses molecular biology techniques to study microbial communities. Many studies have illustrated that greater than 99% of the bacteria found in nature have yet to be cultured in the laboratory. Our challenge is to figure out what these microorganisms are doing in the environment. Molecular tools such as PCR, gene probing, mRNA transcript analysis, and DNA sequencing can aid in this endeavour.Click here for more information on Sinead Ni Chadhain 's research
His research interests include:
- Hypothesis-driven research on self-organization and dynamics of striated muscle and other contractile structures.
- High-resolution microscopy and structural modeling
- Visualization techniques using physical models
- Bioengineering of muscle scaffolds
- Nebulin does not specify actin lengths
He is a broadly trained plant physiologist/cell biologist having worked with algal nitrogen metabolism, herbicide mode of action and acquired herbicide resistance, and developmental biology and physiology of parasitic plants.
Research in the involves the cell biology and physiology in marine systems, especially of freshwater and marine plants and algae. These organisms are the source of most carbon and nitrogen that is added to food chains in the coastal and freshwater areas. Macroalgae and higher plant representatives of these groups have the additional role of serving as sanctuary for the young of many animal species that share their habitat. In spite of their importance in these ecosystems, there are many gaps in our knowledge regarding their physiology and interaction between these and other organisms in these environments.Click here for more information on Tim Sherman's research
His research interests involve amphibian/reptile (herpetofauna) and avian population/community structure within the northern Gulf Coastal Plain Ecosystem. Research projects I have been involved in range from upland sandhills and slope wetlands to large, dynamic river delta systems and estuarine/barrier island herpetofaunal/avian community assessments in coastal Alabama, Florida, and Mississippi. These projects involve a myriad of different objectives from endangered/threatened species population status (Alabama Red-bellied Turtle, Mississippi Diamondback Terrapin, Gopher Tortoise) to species inventories of selected management properties (Mobile-Tensaw Delta, Lillian Swamp, Grand Bay and Weeks Bay NERR) to environmental impacts of anthropogenic disturbances (Deepwater Horizon Oil Spill).Click here for more information on Joel Borden's research
