Residues of organochlorine compounds in starlings (Sturnus vulgaris), 1979
Starlings were collected for the National Pesticides Monitoring Program from 112 sites throughout the contiguous United States and analyzed for organochlorine compounds. Starling samples from 14 sites had greater than 1.0 ppm DDE residues with the highest DDE level being 15.8 ppm in a sample taken near Roswell, New Mexico. The occurrence of PCBs and chlordane isomers increased since the 1976 colle

Effects of dietary cadmium on mallard ducklings
Mallard (Anas platyrhynchos) ducklings were fed cadmium in the diet at 0, 5, 10, or 20 ppm from 1 day of age until 12 weeks of age. At 4-week intervals six males and six females from each dietary group were randomly selected, bled by jugular venipuncture, and necropsied. Significant decreases in packed cell volume (PCV) and hemoglobin (Hb) concentration and a significant increase in serum glutamic

Empirical comparison of uniform and non-uniform probability sampling for estimating numbers of red-cockaded woodpecker colonies
Four sampling and estimation methods for estimating the number of red-cockaded woodpecker colonies on National Forests in the Southeast were compared, using samples chosen from simulated populations based on the observed sample. The methods included (1) simple random sampling without replacement using a mean per sampling unit estimator, (2) simple random sampling without replacement with a rat

Reduced fecundity in small populations of the rare plant Gentianopsis ciliate (Gentianaceae)
Habitat destruction is the main cause for the biodiversity crisis. Surviving populations are often fragmented, i.e., small and isolated from each other. Reproduction of plants in small populations is often reduced, and this has been attributed to inbreeding depression, reduced attractiveness for pollinators, and reduced habitat quality in small populations. Here we present data on the effects o

[Book review] A coded workbook of birds of the World, Vol. 1: Non-passerines (2ndedition)
With a slight change in title, this is the second edition of Edwards' (1974) Coded List, from which it differs significantly. First, it covers only nonpasserines instead of all the birds of the world; presumably a list of the passerines will follow soon. The code is different, the format is expanded, and the information content is greater (3,798 species are listed as opposed to 3,656). This editio

Trends in organochlorine and mercury residues in common loon (Gavia immer) eggs from New Hampshire
Failed eggs collected from New Hampshire common loon (Gavia immer) nests in 1979 (N = 15) and 1981 (N = 21) were analyzed for organochlorines and mercury (Hg). In contrast to reports of previous samplings, DDT was not detected in any egg. PCB and DDE residues showed declining trends. Dieldrin was present at low levels in > 50% of the samples. Eggshell thickness was significantly correlated wit
