Population estimates for the peregrine falcon in Arizona: A habitat inventory approach Population estimates for the peregrine falcon in Arizona: A habitat inventory approach

At least 50 pairs of peregrine falcons reside in Arizona. From aerial surveys of available habitat and occupancy trends at more than 600 sites searched from 1975 to 1985, we estimated that at least 90 pairs resided in the study area. We project a fully recovered population of at least 190 pairs.

An identifiable model for informative censoring An identifiable model for informative censoring

The usual model for censored survival analysis requires the assumption that censoring of observations arises only due to causes unrelated to the lifetime under consideration. It is easy to envision situations in which this assumption is unwarranted, and in which use of the Kaplan-Meier estimator and associated techniques will lead to unreliable analyses.

Lead poisoning in six captive avian species Lead poisoning in six captive avian species

Red-winged blackbirds (Agelaius phoeniceus), brown-headed cowbirds (Molothrus ater), common grackles (Quiscalus quiscula), mallards (Anas platyrhynchos), northern bobwhites (Colinus virginianus), and eastern screech-owls (Otus asio) were poisoned with a concentration of lead (Pb) acetate in the diet which was increased by 60% each week until half of the birds in each treatment group died

Environmental impacts and regulatory policy. Implications of spray disposal of dredged material in Louisiana wetlands Environmental impacts and regulatory policy. Implications of spray disposal of dredged material in Louisiana wetlands

The capabilities of a new wetland dredging technology were assessed along with associated newly developed state and federal regulatory policies to determine if policy expectations realistically match the technological achievement. Current regulatory practices require amelioration of spoil bank impacts upon abandonment of an oil/gas well, but this may not occur for many years or decades...

Winter fasting and refeeding effects on urine characteristics in white-tailed deer Winter fasting and refeeding effects on urine characteristics in white-tailed deer

The effects of dietary protein, fasting, and refeeding on urinary characteristics of 9 captive, female white-tailed deer (Odocoileus virginianus) were studied from 23 February to 3 May 1984. Urinary sodium (na) and potassium (K) were diminished in fasted deer after 2 and 4 weeks. Renal excretion of Na and K were lower, whereas urinary phosphorus (P) was higher in fasted deer compared to...
