The
habitats of far-ranging large marine vertebrates (seabirds, turtles, cetaceans)
and the conservation of oceanic systems
Our
lab's research focuses on understanding how upper-trophic marine predators (cetaceans,
turtles, seabirds) forage and migrate across patchy oceanic environments, and
how these habitat associations make certain species more susceptible to anthropogenic
impacts, such as bycatch. This requires an integrated approach capable of combining
large-scale information on spatial / temporal variability in oceanic processes
with finer-scale studies of predator habitats from tracking and vessel-based surveys.
In particular, our research focuses on four aspects:
Dynamic
Biogeography: What physical and biological factors structure marine communities
and delineate the ranges of pelagic species? How do large-scale inter-annual variability
and longer-term climatic changes affect the persistence of dynamic habitats and
the structure of marine communities?
Foraging
Ecology of Pelagic Predators: What physical mechanisms define predictable
foraging grounds for far ranging upper-trophic predators? How do pelagic predators
search for patchy prey and how does resource dispersion affect their foraging
effort and reproductive success?
Marine
Protected Area Design: How can we integrate knowledge of species natural
histories and physical oceanography to design MPAs in marine systems? How can
MPAs be designed and evaluated with respect to the target species and their habitats
in a constantly shifting environment?
The
Value of Marine birds and Mammals as Biological Indicators: How do top
predator dispersion, diet, and demography reflect marine resource distribution
and abundance? How will species distributions and community structure change in
response to the warming of the global ocean?
