The Saurian Psyche Revisted: Lizards In Research, Neil Greenberg

Faculty Publications and Other Works -- Ecology and Evolutionary Biology

This essay is intended to guide researchers interested in lizards as prospective experimental models to identify an appropriate species for their research needs and to care for lizards in a manner that will not compromise their utility. Coupled with these is a concern for critical thinking about the ethical dimension of lizard research, one guide for which is to consider the intersection of human needs and lizard needs.

Before proceeding further, several arbitrary premises must be made clear:

1. While wholly deserving of study because of their intrinsic interest, I will assume that the lizard research to be undertaken is …

Spiny Lobster Recruitment In South Florida: Quantitative Experiments And Management Implications, Mark J. Butler Iv, William F. Herrnkind

Biological Sciences Faculty Publications

Understanding recruitment and identifying factors critical to that process are imperative if adult spiny lobster Panulirus argus stocks are to be conserved and properly managed. The goal of our research has been to obtain ecological information linking inshore postlarval spiny lobster recruitment to later life stages, thereby providing the basic framework for assessing and predicting adult stock. Since 1983, we have investigated various aspects of spiny lobster recruitment including: postlarval time-to-metamorphosis, postlarval/juvenile habitat selection and selection cues, postlarval/juvenile crypticity and susceptibility to predation, juvenile food preference and emigration, juvenile sociality, and the effect of habitat degradation (i.e., siltration) on postlarval/juvenile …

Seasonal Phytoplankton Development Within Three Rivers In The Lower Chesapeake Bay Region, Harold G. Marshall, Lewis F. Affronti

Biological Sciences Faculty Publications

The seasonal and inter-annual concentrations of phytoplankton were studied over a 50 month period in the lower James, York and Rappahannock Rivers (USA). Differences in the onset, duration and magnitude of major seasonal growth periods varied from year to year. There was a tendency for spring, summer and fall maxima, with a winter period of reduced abundance. An additional study of picoplankton over a 12 month period indicated greatest abundance during summer and fall, with least development in winter.

Metal Concentrations In Blood From An Adult Bald Eagle Nesting At Clinton Reservoir In Kansas, George T. Allen

United States Fish and Wildlife: Staff Publications

Concentrations of metals in blood from an adult male bald eagle nesting at Clinton Reservoir in eastern Kansas in 1991 were analyzed by induction coupled plasma emission spectroscopy without preconcentration.

Because there are very limited data on background levels of most metals in bald eagle blood, the data herein are provided for comparison with other samples at later dates.

Few metals were detected in the sample. The only metal detected that is not physiologically well controlled was mercury. However, the mercury concentration was low compared to concentrations found in blood from bald eagles in the western United States.

Metals And Organic Compounds In Fish And Sediments From The Missouri And Lower Kansas Rivers In Kansas In 1991, George T. Allen

United States Fish and Wildlife: Staff Publications

I sampled sediments and common carp (Cyprinus carpio) at two locations on the Kansas River and two locations on the Missouri River adjacent to Kansas in June 1991. All samples were analyzed for metals, organochlorine compounds, and aliphatic and aromatic hydrocarbons. Sediments also were analyzed for aromatic hydrocarbons.

Concentrations of aluminum, cadmium, chromium, and lead in one or more of the sampling locations are of concern.

In the common carp composites, chlordane compound concentrations were above the level at which detrimental effects might be found at Kansas City and at Bonner Springs. However, there is probably little that can be …

Compositions Of Bud And Leaf Exudates Of Some Populus Species, W. Greenaway, J. May, T. Scaysbrook, F.R. Whatley

Aspen Bibliography

Bud and leaf exudates from Populus alba, P. balsam ifera, P. nigra and P. tremuloides were analyzed by gas chromatography/mass spectrometry and their components were identified. For three of the four species, P. alba, P. balsam ifera and P. nigra, the bud and leaf exudates were similar within each species, though there were marked differences between species. Bud and leaf exudates of P. alba contained only hydrocarbons, those of P. balsam ifera contained primarily dihydrochalcones and those of P. nigra contained primarily caffeic acid esters. Bud and leaf exudates of P. tremuloides were different both from each other and from …
