Texas A&M University
Education:
B.S. (Marine Biology) -
University of California Los Angeles (1995)
Ph.D. (Biology) – University of California Los Angeles (2003)
Specialty:
Coastal and wetlands
community ecology in salt marshes, tidal mudflats, and seagrass
beds, with particular focus on changes in trophic structure
following habitat restoration, nutrient enrichment, and other human
disturbances.
Research Interests:
Anthropogenic nutrient
enrichment impacts many coastal ecosystems, and a major component of
my research addresses how nutrient supply influences trophic
interactions in tidal marshes, seagrass beds, and coral reef
habitats. I evaluate the impacts of nutrient enrichment and habitat
restoration on marine communities using two general approaches: 1)
characterizing responses of species assemblages (e.g., epiphytic
microalgae, benthic macrophytes, epifauna), and 2) evaluating
changes in herbivory and predation patterns. I have quantified
trophic responses to enrichment or habitat restoration through
direct measures of fitness, predation rates, and herbivory pressure,
and am currently using isotopic signatures to evaluate food web
structure.

Education:
B.S. - Penn State University (1970)
M.S. - Florida State University (1973)
Ph.D. - University of Texas Medical Branch (1977)
Specialty:
Marine Cave
Biology and Diving Research. Biodiversity, ecology, biogeography and
evolution of marine cave fauna; conservation biology and endangered
species; technical scientific diving including cave, nitrox,
rebreather and trimix diving.
Research Interests:
My primary
research involves biodiversity surveys of the animals inhabiting
saltwater caves. I have led research expeditions for studies of the
biology of marine and freshwater caves to the Bahamas, Belize,
Mexico, Jamaica, Canary Islands, Iceland, Balearic Islands, Romania,
Czechoslovakia, Galapagos, Hawaii, and numerous other locations in
the Indo-Pacific; in addition to 9 years of studies on Bermuda's
marine caves. This research has resulted in the discovery of more
than 250 new species of marine animals, mostly crustaceans,
inhabiting caves on islands in the Atlantic, Caribbean and
Indo-Pacific. While a number of these animals are exceptionally
primitive “living fossils”, others are related to deep sea forms.
Amazingly, many of these cave-limited species have close relatives
inhabiting caves on opposite sides of the Earth. Much of my research
involves uses of specialized diving techniques including cave diving
using sidemounted tanks (to lower the diver’s profile) and
closed-circuit rebreathers (to lengthen bottom times and reduce
diver disturbance by exhaust bubbles). Additional information on my
cave research can be found on my website at:

Specialty:
Vertebrate Functional
Morphology and Biomechanics
Research Interests:
My area of research is
comparative functional organismal biology and ecomorphology. My
research program integrates morphology and behavioral performance
studies of vertebrates to understand organismal adaptations to their
environment. Specifically I am interested in how vertebrates
detect, acquire, ingest and digest food, and how these systems
affect behavioral performance and foraging ecology. Such studies
integrate several research tools including classic animal
dissections, histology, electron microscopy, kinematics (motion
analysis), electromyography and other electrophysiological
techniques. Recent research topics investigate the feeding apparatus
and foraging behavior in benthic foraging marine mammals. Other
interests include: comparative neurobiology, and the evolution and
function of sensory systems.

Education:
Ph.D. University of Texas
(1997)
M.S. University of Puerto Rico (1991)
B. A. Gustavus Adolphus College (1985)
Specialty:
Ecology of estuarine,
coastal, and pelagic fishes; recruitment processes, particularly
factors affecting early life growth and survival; life history and
migration studies; analytical approaches to fish demography.
Research Interests:
My research centers on the
community and population ecology of aquatic organisms, with a
special emphasis marine fishes. I am particularly interested in
linkages between habitat selection, individual responses, and
survival during early life stages. My work is both laboratory and
field-based, and I typically use both quantitative and experimental
approaches to elucidate the importance of biotic and abiotic factors
that influence early life growth, condition, and survival. The scope
of my research has expanded significantly in the last decade, and we
are currently using a variety of natural markers to solve ecological
problems. For example, otolith chemistry is being used to
retrospectively determine the environmental histories of marine
fishes. The premise of otolith chemistry is that certain elements or
isotopes are incorporated into otoliths in proportion to their
concentrations in the environment, and thus we use these elemental
fingerprints to distinguish individuals from different environments
or regions. Also, we are using dietary tracers (stable isotopes,
fatty acids) to investigate marine food web structure since consumer
tissues reflect the isotopic and fatty acid composition of prey in a
predictable. These natural biomarkers provide time-integrated or
long-term measures of diet, and both approaches afford information
on source(s) of organic matter supporting local food webs as well as
trophic relationships of associated consumers.
