Optimizing atrazine catabolism in Pseudomonas sp. strain ADP

Optimizing atrazine catabolism in Pseudomonas sp. strain ADP.
Creator
Anderson, Robert., Harriet L. Wilkes Honors College
Abstract/Description
Atrazine is a popular herbicide used in over 80 countries to inhibit the growth of broadleaf and grassy weeds. Atrazine is a common pollutant in soil and groundwater, and high concentrations of atrazine cause developmental defects in fish, amphibians, and birds. The bacteria Pseudomonas sp. strain ADP (P.ADP) uses atrazine as a nitrogen source by transforming atrazine to ammonia through a number of enzymatic reactions. In this project I measured the growth and atrazine degradation of P.ADP in...
Show moreAtrazine is a popular herbicide used in over 80 countries to inhibit the growth of broadleaf and grassy weeds. Atrazine is a common pollutant in soil and groundwater, and high concentrations of atrazine cause developmental defects in fish, amphibians, and birds. The bacteria Pseudomonas sp. strain ADP (P.ADP) uses atrazine as a nitrogen source by transforming atrazine to ammonia through a number of enzymatic reactions. In this project I measured the growth and atrazine degradation of P.ADP in media with atrazine as the sole nitrogen source. A mutant strain isolated after mutagenesis with UV light showed faster growth and reached higher densities than the control strain. A series of mating experiments were performed to determine whether the growth mutation was on the atrazine degrading plasmid or in the chromosome. The limitations and potential of P.ADP for atrazine degradation are discussed.

Diet and Nesting Habitat of Wading Birds in a Shallow, Eutrophic Lake.
Creator
May, Jenna C., Gawlik, Dale E., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
Avian reproductive success varies depending on environmental conditions, degree of predation, location, and food availability. I examined food availability and nesting habitat of wading birds in South Florida. Evaluating prey availability and prey used by two small heron species demonstrated the ability for small herons to maintain consistent diets through fluctuating environmental conditions, within and across different wetland types.

Show moreAvian reproductive success varies depending on environmental conditions, degree of predation, location, and food availability. I examined food availability and nesting habitat of wading birds in South Florida. Evaluating prey availability and prey used by two small heron species demonstrated the ability for small herons to maintain consistent diets through fluctuating environmental conditions, within and across different wetland types. Small herons may be able to cope with environmental changes by altering foraging locations and strategies. Regarding nesting habitat, man-made sites may provide habitat comparable to natural sites, at least in the short-term. The nest’s position can influence its susceptibility to increased temperatures and predators, particularly for. Climatic conditions such as rainfall can also impact nesting success by altering foraging conditions and fish behavior. Understanding the effects of hydrologic regimes on biota can have practical applications since ecosystems around the world share similar problems with competing demands for resources, and there is a concern for how use can affect the quality of the resource.

Diet and foraging ecology of diamondback terrapins (Malaclemys Terrapin) in south Florida
Title
Diet and foraging ecology of diamondback terrapins (Malaclemys Terrapin) in south Florida.
Creator
Denton, Mathew, Baldwin, John D., Florida Atlantic University, Charles E. Schmidt College of Science, Center for Environmental Studies
Abstract/Description
Dietary resource use for diamondback terrapins (Malaclemys terrapins) in subtropical mangrove habitats in south Florida creeks and islands was examined to elucidate long-term individual foraging strategies. Fecal analysis revealed seven categories of food items with gastropods, crabs, and bivalves being the most dominant food items respectively. Non-metric multidimensional scaling revealed differences in habitat, but not terrapin size class. Stable isotope analysis confirmed the findings,...
Show moreDietary resource use for diamondback terrapins (Malaclemys terrapins) in subtropical mangrove habitats in south Florida creeks and islands was examined to elucidate long-term individual foraging strategies. Fecal analysis revealed seven categories of food items with gastropods, crabs, and bivalves being the most dominant food items respectively. Non-metric multidimensional scaling revealed differences in habitat, but not terrapin size class. Stable isotope analysis confirmed the findings, identifying habitat and site differences in δ13C and δ15N values for both terrapins and their prey. Bi-plots of terrapin and potential prey δ 13C and δ 15N values revealed potential dietary sources previously undetermined by fecal analysis. Comparisons of scute and blood isotope data revealed significant differences in δ13C indicating potential shifts in either food resources and/or habitat use through the time period recorded in the scute tissue. These tissue comparisons represent a powerful tool for estimating long term foraging strategies for a key estuarine species.
