  • Role of priority effects and habitat complexity in coral-reef fish communities

    Creator:
    Almany, Glenn R.
    Abstract:
    Understanding the processes that influence the composition of animal communities is a central goal in ecology. Interactions between established residents and colonizing juveniles that affect the subsequent survival of juveniles may influence community composition. In a series of experiments on coral reef fish communities in the Bahamas and Australia, I...

  • 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...

  • 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...

  • Factors affecting the dynamics and regulation of coral-reef fish populations

    Creator:
    Webster, Michael Scott
    Abstract:
    Ecologists have long questioned why fluctuating populations tend to persist rather than go extinct. Populations that persist indefinitely are regulated by mechanisms that cause demographic density dependence, which works to bound fluctuation above zero. In a series of studies, I have sought to determine the processes and mechanisms that regulate...

  • Population dynamics of coral-reef fishes : spatial variation in emigration, mortality, and predation

    Creator:
    Overholtzer-McLeod, Karen L.
    Abstract:
    Understanding the dynamics of open marine populations is difficult. Ecological processes may vary with the spatial structure of the habitat, and this variation may subsequently affect demographic rates. In a series of observational and experimental studies in the Bahamas, I examined the roles of emigration, mortality, and predation in the...

  • 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...

  • 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...

  • 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...

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

    Creator:

    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...
