  • 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...

  • Selection on larval and adult body size in a marine fish: potential evolutionary responses and effects on population dynamics

    Creator:
    Johnson, Darren W.
    Abstract:
    Many species have complex life cycles in which a dispersive larval stage is followed by a relatively sedentary adult stage. For such species, reproductive output is often high and large variation in survivorship throughout early life-history phases (eggs and larvae) can lead to dramatic fluctuations in recruitment which may in...

  • Spinal control differences between the sexes

    Creator:
    Johnson, Samuel T.
    Abstract:
    Despite years of research, females continue to have a higher incidence of non-contact ACL injuries. One of the major findings of this research is that males and females perform certain tasks, such as, cutting, landing, and single-leg squatting, differently. In particular, females tend to move the knee into a more...

  • Marine reserves in The Bahamas and Ecuador : a scientific and socioeconomic perspective

    Creator:
    Lamb, Robert W.
    Abstract:
    Marine reserves are known to directly replenish overfished species. However, the community-wide effects of reserves are less clear. I examined the community of coralreef fishes in a large, fully protected marine reserve in The Bahamas: the Exuma Cays Land and Sea Park. Visual-transect surveys provided estimates and comparisons of the...

  • Predicting the effects of climate change : effects of thermal stress on seaweeds in the Galapagos rocky intertidal

    Creator:
    Harris, Alyssa L.
    Abstract:
    Because global warming is predicted to increase the severity of El Niño events in the future, understanding how warmer temperatures affect seaweed growth and the animals associated with seaweeds is important for predicting how marine ecosystems will change. The Galapagos Islands of Ecuador are considered a living laboratory for studying...

  • Efficacy of electrolyzed oxidizing water and ozonated water for microbialdecontamination of fresh strawberries (Fragaria x ananassa)

    Creator:
    Udompijitkul, Pathima
    Abstract:
    The objectives of this project were to evaluate the efficacies of electrolyzed oxidizing (EO) and ozonated waters as antimicrobial agents for enhancing the microbiological safety of fresh strawberries (Fragaria x ananassa). The influence of sodium chloride (NaCl) concentrations used for preparing EO water was evaluated on their bactericidal activities against...

  • Indirect effects of fishing on predators and their prey

    Creator:
    Stallings, Christopher Derek
    Abstract:
    Predators are fundamentally important for regulating and driving prey population dynamics as well as structuring ecological communities. Over-exploitation of marine resources has caused dramatic depletions of predatory fish species and shifts in marine community composition, with attendant declines in productivity and diversity of marine ecosystems. Despite the important ramifications of...

  • Investigation of the biomechanics of running and rapid change-of-direction tasks

    Creator:
    Golden, Grace M.
    Abstract:
    Rapid change-of-direction tasks have been associated with non-contact anterior cruciate ligament (ACL) injuries and females are more likely to suffer this injury compared to males. The purpose of this investigation was to evaluate the biomechanical behavior of running and three rapid change-of-direction tasks and determine whether sex differences exist across...

    Creator:
    Hayes, Bradley T.
    Abstract:
    The purpose of this research was to evaluate the effects of a long-term static stretching program on flexibility and spinal reflexes in the human soleus muscle. Day-to-day reliability over two days of H-reflex gain (Hslp/Mslp) and pre-synaptic inhibition of spinal reflexes in the human soleus was measured in an initial...
