研究领域

Marine larval supply-side ecology. I have begun designing an apparatus that will sample potential recruiting invertebrate larvae and algal spores on a continual basis and provide instantaneous digital information on abundances. By providing less-expensive, continuous monitoring and rapid data analysis, this project may help shed some light on what has been termed the "larval mystery phase" - a factor which may strongly influence the development and succession in intertidal and subtidal communities. Neotropical Migrant Birds. Populations of many songbirds continue to decline in the United States. A simple monitoring program for populations and habitat is fairly easy to establish and may be a great way to involve undergraduates with an interesting beginning research project. Coral reef ecology. Coral reefs are important regions of valuable high biological diversity and yet they appear to be in trouble globally due to over harvesting of associated fishes, increased coastal eutrophication and siltation as well as increasing ultraviolet radiation. I would like to maintain my involvement with coral reef studies through continued periodic returns to monitoring sites established during my dissertation research as well as participation in some of the new global coral reef monitoring programs. Deep reef ecology. My dissertation research has merely scratched the surface of this potentially information-rich study area. I would like to continue the process of determining the taxa present on the slopes of the Great Bahama Bank (30 - 300m) and possibly start some experimental tests of hypotheses explaining the high diversity present on these slopes. I'd also like to find the deep-dwelling trilobites that deep-ocean marine scientists jokingly long to see. California Gray Whales. Continue work on determining the extent and variation of offshore and estuarine benthic swarms of mysids, cumaceans and amphipods as possible food sources for migrating or resident California Gray Whales. Expansion and continuation of Craig Hawkinson's observations and record keeping on resident and migrating Gray Whales. Humpback Whales. Passive acoustic tracking of migrating pods. This project would utilize existing US Navy submarine technology and vessels as part of the US Navy's desire for cooperative ventures with civilian academic research. Whales would be tracked passively using the forward acoustic array. This would shed light on questions regarding migratory behavior and the routes followed. The routes followed by humpbacks have long been a mystery. This would be valuable to the Navy, cetacean research and other researches such as those of Scripps global warming acoustic research concerned about the location of Humpbacks (for their protection). Beaver. I have two fairly well-developed proposals for beaver-ecology research: a) pollen and phytolith stratigraphy of sediments impounded in beaver dams and ponds as an indication of local vegetation community change over decade and century time-scales; b) vegetation community comparisons among riparian zones inhabited and not-inhabited by Castor canadensis (introduced into Tierra del Fuego in 1945 and currently flourishing). Horses. I would like to use carbon and oxygen isotope ratios in tooth enamel to determine whether a dietary shift hypothesis might be supported regarding late Pleistocene North American equids. This would be a further exploration of the Pleistocene overkill hypothesis vs. climatic shift hypothesis as explanations for the late Pleistocene demise of N.A. equids and presumably other megafauna.
