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...

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...

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...

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...

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...

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...

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...

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...
