Testing for variation in taxonomic extinction probabilities: A suggested methodology and some results Testing for variation in taxonomic extinction probabilities: A suggested methodology and some results
Several important questions in evolutionary biology and paleobiology involve sources of variation in extinction rates. In all cases of which we are aware, extinction rates have been estimated from data in which the probability that an observation (e.g., a fossil taxon) will occur is related both to extinction rates and to what we term encounter probabilities. Any statistical method for...

Population trends and environmental contaminants in herons in the Tennessee Valley, 1980-81 Population trends and environmental contaminants in herons in the Tennessee Valley, 1980-81
Great Blue Heron (Ardea herodias) eggs (N = 40) collected in 1980 from four of the largest colonies in the Tennessee Valley contained organochlorine pesticide, polychlorinated biphenyl (PCB), and chromium concentrations below those associated with reduced productivity. Low concentrations of organochlorine pesticide and PCB residues also were found in eggs (N = 31) from three of the...

Organochlorine pesticide residues in moths from the Baltimore, MD-Washington, D.C. area Organochlorine pesticide residues in moths from the Baltimore, MD-Washington, D.C. area
Moths were collected with a light trap from 15 sites in the Baltimore, Maryland-Washington, D.C. area and analyzed for organochlorine pesticide residues. On the average, the species sampled contained 0.33 ppm heptachlor-chlordane compounds, 0.25 ppm DDE, and 0.11 ppm dieldrin. There were large differences in the concentrations detected in different species. Concentrations were especially...

A general methodology for maximum likelihood inference from band-recovery data A general methodology for maximum likelihood inference from band-recovery data
A numerical procedure is described for obtaining maximum likelihood estimates and associated maximum likelihood inference from band- recovery data. The method is used to illustrate previously developed one-age-class band-recovery models, and is extended to new models, including the analysis with a covariate for survival rates and variable-time-period recovery models. Extensions to R-age...
