  • 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...

  • 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...

  • 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...
