  • Habitat Use and Ecological Interactions of Invasive Lionfish in the Bahamas

    Creator:
    Davis, Alexandra C. D.
    Abstract:
    Invasive species are a growing global economic and ecological problem. Invasive Indo-Pacific lionfish (Pterois spp.) are known to have extreme negative effects on coral-reef communities in the Bahamas, so understating their distribution within and among reefs, what limits their local movements, and the effects they have on native prey species...

  • Effects of Predator Introductions on Population and Community Dynamics

    Creator:
    Ingeman, Kurt E.
    Abstract:
    There is increasing awareness that human activities are altering the ways that natural systems operate and that local shifts in species composition and abundance can lead to abrupt and irreversible global change. Therefore, understanding the processes that buffer biological communities from critical shifts and how our actions affect natural stabilizing...

  • Invasive Pacific Lionfish Alters Native Community Interactions on Atlantic Coral Reefs

    Creator:
    Kindinger, Tye L.
    Abstract:
    Biological invasions have been identified as one of the prominent drivers of global environmental change. In particular, invasive predators typically have substantial negative effects on populations of native prey, even driving species to extinction in extreme cases. However, beyond direct predatory effects, little is understood regarding the specific mechanisms by...

  • Behavior and Ecological Effects of Invasive Lionfish on Atlantic Coral Reefs and Seagrass Beds

    Creator:
    Benkwitt, Cassandra E.
    Abstract:
    Although only a minority of introduced species become established and have noticeable consequences in their new communities, some can displace native species, alter food webs, and cause local extinctions. Studying these invasive species can provide new insights into basic ecological questions as well as inform management strategies. Pacific lionfish (Pterois...

  • Interactions among Invasive Pacific Red Lionfish, Fish Parasites, and Cleaning Mutualisms Native to Atlantic Coral Reefs

    Creator:
    Tuttle, Lillian J.
    Abstract:
    What makes invasive species successful, and how do they affect native populations and communities? I addressed these key questions in the context of the invasion of Atlantic coral reefs by Pacific red lionfish (Pterois volitans). To assess the role of parasites in contributing to the success of this invasion, I...

  • The effects of plyometrics on neuromuscular control

    Creator:
    Doeringer, Jeffrey R.
    Abstract:
    The purpose of this study was to determine the effects of plyometric training on both spinal and supraspinal motor control as well as the rate of torque development (RTD) in healthy active females. Thirty-one subjects were recruited to participate in the study and participated in either the training or control...

  • Coral-reef fishes : insights into larval dispersal and invasion ecology

    Creator:
    Pusack, Timothy J.
    Abstract:
    Because many coral-reef fishes are observable in situ, are amenable to transplantation, have small home ranges and short generation times, they provide a excellent system to investigate many topics within general ecology, fisheries biology, and conservation biology. The primary goal of this dissertation was to use the coral-reef fishes system...

  • Effects of the invasive Pacific red lionfish Pterois volitans on native Atlantic coral-reef fish communities

    Creator:
    Albins, Mark A.
    Abstract:
    Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...

  • Spinal reflex control in healthy and ACL-injured women during a distracting task

    Creator:
    Perrier, Erica Taylor
    Abstract:
    Female athletes exhibit three- to six-fold greater incidence of noncontact anterior cruciate ligament (ACL) injury relative to their male counterparts. The increased risk appears to stem from interactions between several risk factors, that can roughly be categorized as anatomic, biomechanical, hormonal, and neuromuscular. Neuromuscular risk factors have recently gained a...

  • Larval dispersal in marine fishes: novel methods reveal patterns of self-recruitment and population connectivity

    Creator:
    Christie, Mark R.
    Abstract:
    Many marine fish populations are severely declining due to over-fishing, loss of both juvenile and adult habitats, and accelerating environmental degradation. Fisheries management and the implementation of marine protected areas (MPAs) and other conservation tools are currently hindered by large gaps in knowledge about larval dispersal and its subsequent effects...
