Title: Intraspecific aggression in the difficult ant, Technomyrmex difficilis (Hymenoptera: Formicidae).
Creator: Sollins, Benjamin H., Harriet L. Wilkes Honors College
Abstract/Description: One mechanism allowing ant species to successfully invade new areas at a rapid pace is unicoloniality, the formation of large networks connecting colonies over hundreds or even thousands of kilometers. These large networks of colonies, or "supercolonies" lack any form of intraspecific aggression, thus fighting between them is absent. I used aggression assays to study unicoloniality between colonies of the invasive difficult ant, Technomyrmex difficilis on the Florida Atlantic University...
Show moreOne mechanism allowing ant species to successfully invade new areas at a rapid pace is unicoloniality, the formation of large networks connecting colonies over hundreds or even thousands of kilometers. These large networks of colonies, or "supercolonies" lack any form of intraspecific aggression, thus fighting between them is absent. I used aggression assays to study unicoloniality between colonies of the invasive difficult ant, Technomyrmex difficilis on the Florida Atlantic University Wilkes Honors College campus and a household located ~32 km northwest from the college. I found that for all trial combinations, no aggression took place among the ants. From these results, I conclude that T. difficilis does display unicoloniality in South Florida.

Title: The influence of public access on raccoon predation on sea turtle nests in Boca Raton, Florida.
Creator: VanDam, Andrea., Harriet L. Wilkes Honors College
Abstract/Description: In the Eastern United States, the Florida coastline provides 85% of all nesting sites for the green (Chelonia mydas), leatherback (Dermochelys coriacea), and loggerhead (Caretta caretta) sea turtles. Palm Beach County beaches experience some of the highest nesting frequencies, but recreational use of the beaches has increased threats like raccoon predation. The Gumbo Limbo Nature Center (GLNC) in Boca Raton (founded in 1984) keeps records of nests and predators to the nests. I analyzed 4554...

Palm Beach County beaches experience some of the highest nesting frequencies, but recreational use of the beaches has increased threats like raccoon predation. The Gumbo Limbo Nature Center (GLNC) in Boca Raton (founded in 1984) keeps records of nests and predators to the nests. I analyzed 4554 GLNC nest records from 2002-2007 to examine whether raccoon predation of turtle nests was most prevalent in areas of high human impact. I found that raccoon predation occurred at significantly higher rates in areas with public access to the beach than in areas without such access (high access: 50.8%, low access: 14.4%, overall: 36.4%). This suggests the necessity of increased protection of nests in areas of high access for the preservation of nesting populations.

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.

Title: Habitat selection among fishes and shrimp in the pelagic Sargassum community: the role of habitat architecture.
Creator: Bennice, Chelsea, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: Pelagic Sargassum was used to determine the effects of habitat architecture for one species of shrimp (Leander tenuicornis) and two species of fish (Stephanolepis hispidus and Histrio histrio). Inter-thallus spacing (low, medium, and high) and depth (shallow versus deep) were manipulated independently to test whether the spatial components of habitat architecture.

Inter-thallus spacing (low, medium, and high) and depth (shallow versus deep) were manipulated independently to test whether the spatial components of habitat architecture. Two differing habitats (Sargassum versus seagrass species) were tested for the structural component of habitat architecture. There were no significant results for inter-thallus spacing experiments for L. tenuicornis and S. hispidus. H histrio selected habitats with medium inter-thallus spacing in two treatments. Large individual H. histrio contributed mostly to the significant effects. All three species selected habitats with a greater depth aspect. Finally, L. tenuicornis and H. histrio selected habitats with greater structural complexity (i.e., Sargassum). These results demonstrate clearly that habitat architecture of Sargassum influences habitat selection by these shrimp and fishes.

Title: Wading Bird Reproductive and Physiological Responses to Environmental Disturbance in a Managed Lake Ecosystem.
Creator: Chastant, Jennifer E., Gawlik, Dale E., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences

Show moreWetlands are some of the most diverse and productive ecosystems on earth. Water-level fluctuations determine the ecological function of shallow lakes and wetlands. Currently, anthropogenic modification to water-level fluctuations is the leading source of ecological degradation in lake and wetland ecosystems worldwide. I used wading birds nesting in Lake Okeechobee, as a model system to address the challenges of environmental restoration within an ecosystem greatly impacted by anthropogenic activities. Specifically, I 1) identified environmental factors most important for predicting the number of wading bird nests, 2) tested the assumptions of both the match-mismatch and the threshold hypothesis by modeling the relationship between nesting success and prey density with foraging habitat availability, and 3) measured the stress response of Great (Ardea alba) and Snowy Egrets (Egretta thula) to hydrologically-mediated changes in food availability. Collectively, the results suggest that the number of nests was greatest when area of nesting substrate was high and water-levels were moderate (3.9 - 4.4 m). Nest numbers dropped when either nesting substrate or foraging habitat was limited. My investigation into the predictions of the match-mismatch and threshold hypotheses found that indeed, prey density can reduce or intensify the effects of a mismatch event. The interaction of prey density and foraging habitat availability was significant and positive in both models. Saturation thresholds existed for both fledging success (147 prey (m^2)^-1) and total productivity (189 prey (m^2)^-1), above which high concentrations of prey could sustain nesting when foraging habitat availability was low. Finally, my studies of the stress response support the hypothesis that hydrologic factors associated with prey availability play an important role in regulating nesting patterns, although the level of food limitation the birds experience at the lake was not as severe as expected. Model selection identified foraging habitat availability as most influential to the nestling Great Egret stress response, whereas foraging habitat availability and prey density both influenced nestling Snowy Egret stress response. Moreover, the Snowy Egret stress response was more sensitive to changes in prey availability than was the Great Egret stress response. Temperature and foraging conditions influenced yolk corticosterone concentrations for both egret species.

Title: Prey selectivity of the fishes Stephanolepis hispidus and Histrio histrio on the Sargassum shrimps Latreutes fucorum and Leander tenuicornis.
Creator: Hutchinson, Kimberly A., Florida Atlantic University, Brooks, W. Randy
Abstract/Description: Predator-prey relationships were studied between the shrimps Latreutes fucorum and Leander tenuicornis and the predatory fishes Stephanolepis hispidus and Histrio histrio, all found within pelagic Sargassum communities. Average survival times of shrimps were compared in species, size/density, and habitat selection studies. The results showed that S. hispidus had a preference for prey species while H. histrio did not. 30 mm shrimp survived longer than the 10 mm shrimp for both S. hispidus and...

Average survival times of shrimps were compared in species, size/density, and habitat selection studies. The results showed that S. hispidus had a preference for prey species while H. histrio did not. 30 mm shrimp survived longer than the 10 mm shrimp for both S. hispidus and H. histrio. Density was a factor in the survival times of the 20 mm shrimps with S. hispidus only. L. tenuicornis survived longer in artificial Sargassum habitats with H. histrio. The larger shrimps survived longer in the artificial habitats than the smaller shrimps with S. hispidus. Both fish predators employ optimal foraging strategies with similarities and differences, the latter of which are likely related to behavioral differences in the these predator and prey.

Title: Nematocyst replacement in the sea anemone Aiptasia Pallida following predation by Lysmata Wurdemanni: an inducible defense?.
Creator: Jennings, Lucas, Laramore, Susan E., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: The sea anemone Aiptasia pallida is a biological model for anthozoan research. Like all cnidarians, A. pallida possesses nematocysts for food capture and defense. Studies have shown that anthozoans, such as corals, can rapidly increase nematocyst concentration when faced with competition or predation, suggesting that nematocyst production may be an induced trait. The potential effects of two types of tissue damage, predator induced (Lysmata wurdemanni) and artificial (forceps), on nematocyst...

The potential effects of two types of tissue damage, predator induced (Lysmata wurdemanni) and artificial (forceps), on nematocyst concentration was assessed. Nematocysts were identified by type and size to examine the potential plasticity associated with nematocyst production. While no significant differences were found in defensive nematocyst concentration between shrimp predation treatments versus controls, there was a significant difference in small-sized nematocyst in anemones damaged with forceps. The proportions of the different types of nematocysts between treatment types were also found to be different suggesting that nematocyst production in A. pallida is a plastic trait.

Title: TROPHIC INTERACTIONS OF OCTOPUS VULGARIS AND THE IMPACTS OF PLASTIC LEACHATE OLEAMIDE.
Creator: Hair, Madelyn A., McCoy , Michael, Florida Atlantic University, Department of Marine Science and Oceanography, Charles E. Schmidt College of Science
Abstract/Description: Octopus predation and species selection contribute to community structure in benthic habitats, where plastic pollution accumulates. This study investigated how the bioactive plastic additive oleamide alters trophic interactions and behaviors of the common octopus (Octopus vulgaris) and its prey. We quantified activity budgets and trophic interactions for octopuses and multiple prey types (hermit crabs, free-living crabs, bivalves, and gastropods) before and after exposure to oleamide. Our...
Show moreOctopus predation and species selection contribute to community structure in benthic habitats, where plastic pollution accumulates. This study investigated how the bioactive plastic additive oleamide alters trophic interactions and behaviors of the common octopus (Octopus vulgaris) and its prey. We quantified activity budgets and trophic interactions for octopuses and multiple prey types (hermit crabs, free-living crabs, bivalves, and gastropods) before and after exposure to oleamide. Our analysis suggested that some taxa (octopuses and hermit crabs) exhibit more active behaviors during oleamide exposure. Free living crabs responded primarily to the threat of octopus predation, while other taxa did not show clear behavioral responses. Exposure to oleamide increased trophic interactions and the probability of mobile prey taxa being observed on the same side of the aquarium as the octopus, thus increasing the opportunity for predation. Our results support previous research showing that plastic leachates can impair decision-making, making prey more susceptible to predation.

Title: A Novel Interaction: The thin stripe hermit Crab, Clibanarius vittatus, kills the Florida crown conch, Melongena corona, for its shell.
Creator: Cutter, Jennifer, Devlin, Donna, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: The hermit crab Clibanarius vittatus kills Melongena corona solely to acquire a better fitting shell. This finding is contrary to previous studies, which found that hermit crabs of other species cannot kill gastropods or, in most instances, remove freshly dead gastropods from their shells. This interaction cannot be classified as predation because Melongena tissue was never consumed. Clibanarius killed Melongena only when by doing so they could trade up to a better fitting shell.

Show moreThe hermit crab Clibanarius vittatus kills Melongena corona solely to acquire a better fitting shell. This finding is contrary to previous studies, which found that hermit crabs of other species cannot kill gastropods or, in most instances, remove freshly dead gastropods from their shells. This interaction cannot be classified as predation because Melongena tissue was never consumed. Clibanarius killed Melongena only when by doing so they could trade up to a better fitting shell. It cannot be classified as competition because there is no opportunity for Melongena to gain from the interaction. Therefore the term “lethal eviction” is hereby proposed for this interaction. The ability to kill a gastropod to obtain a superior shell gives Clibanarius vittatus an evolutionary advantage over other hermit crab species. It is not known if the outcome of this interaction is widespread where both species occur or if it is confined to the study area.
