An evaluation of blood plasma for monitoring DDE in birds of prey
Laboratory and field studies show that DDE residues in blood plasma are highly correlated with DDE in the brain, the rate of DDE exposure and the amount of DDE in eggs of free-living birds of prey. A blood sampling approach is proposed to supplement existing environmental contaminant methods available for birds of prey. Residues (ΣDDT) in plasma provide some direct information; however, a method i

Marine turtles of the Gal?pagos Islands and adjacent areas of the eastern Pacific on the basis of observations made by J.R. Slevin 1905-1906
The field notes of J. R. Slevin written during the expedition of the California Academy of Sciences to the Galapagos Islands in 1905-1096 contain previously unavailable data on the marine turtles of the eastern Pacific. 'Land basking' by green turtles in Galapagos was predominately, if not exclusively, a female behavior. These terrestrial emergences were not concentrated in the major reproductive

Colony site dynamics and habitat use in Atlantic coast seabirds
Seabird colony sizes and movements were documented in the DelMarVa coastal region in 1976-1977 and in New Jersey in 1978-1979. Most colonies were found on marsh and dredge deposition islands and on barrier island beaches. For the "traditionally" beach-nesting Herring Gull, Common Tern, and Black Skimmer, larger, more stable colonies were found on barrier beaches than on marsh islands. In marsh hab

Pharmocokinetics of cephalothin and cephalexin in selected avian species
Plasma concentrations and the biological half-lives of cephalothin and cephalexin in avian species of a variety of body sizes and metabolic rates were studied. The species chosen were eastern bobwhite quail (Colinus v virginianus), pigeons (Columba livia), hybrid rosybill ducks (Netta sp), greater sandhill cranes (Grus canadensis tabida), and emus (Dromiceius novaehollandiae). In the 1st phase of

Gentamicin tissue concentration in various avian species following recommended dosage therapy
Plasma and tissue drug concentrations were compared in eastern bobwhite quail (Colinus virginianus virginianus) and pigeons (Columba livia) given gentamicin by IM administration at the dosage of 10 mg/kg, and in greater sandhill cranes (Grus canadensis tabida) and hybrid rosybill ducks (Netta sp) given the same antibiotic at a dosage of 5 mg/kg. Quail and cranes had significantly higher liver conc

Importance of structural stability to success of mourning dove nests
Studies of nest-site selection and nesting habitats often involve a "characterization" of nests and of habitats in which nests are found. Our objective in the present work is to identify nest-site characteristics that are associated with variation in components of Mourning Dove (Zenaida macroura) fitness (e.g. the probability of a nest succeeding), as opposed to simply "characterizing" dove nest s
