Diabetes mellitus in a black-footed ferret
Diabetes mellitus was tentatively diagnosed in a black-footed ferret with polyuria, polydipsia, polyphagia, dehydration, and weight loss. Laboratory findings (marked hyperglycemia (724 mg/100 ml), glycosuria, and ketonuria) and the subsequent favorable response to insulin therapy confirmed the diagnosis. Although lesions were not observed in the pancreas, gross and histologic findings concomitant

Unretrieved shooting loss of mourning doves in north-central South Carolina
Unretrieved loss for mourning doves (Zenaida macroura) in north-central South Carolina was between 27 and 41 percent of the retrieved kill for the 1973 through 1975 hunting seasons based on 1,396 doves shot by 281 hunters. Dove hunters hunted in groups, fired 8.6 shots per retrieved dove, and engaged in a substantial number of illegal activities. Increased dove populations and hunter bag resulted

Mid-Atlantic coast osprey population: Present numbers, productivity, pollutant contamination, and status
An estimated 233 + 16 (95% C.I.) pairs of ospreys (Pandion haliaetus) nested in coastal New Jersey, Delaware, Maryland, and Virginia in 1975. The present populations were considerably smaller than those reported for selected locations at the turn of the century in these four states. The New Jersey population has continued to decline during the last 25 years, although it showed some signs of impr

Verification of a model for predicting the effect of inconstant temperature on embryonic development of lake whitefish (Coregonus clupeaformis)
Eggs stripped from lake whitefish (Coregonus clupeaformis) spawning in Lake Michigan were incubated in the laboratory at temperatures similar to those on whitefish spawning grounds in Lake Michigan during December-April. Observed times from fertilization to attainment of each of 21 developmental stages were used to test a model that predicts the rate of development at daily fluctuating temperature

The use of feeding habitat by a colony of herons, egrets, and ibises near Beaufort, North Carolina
Nine species of herons were followed to their feeding sites from a nesting colony near Beaufort, North Carolina, by airplane. Except for the Cattle Egret, which flew exclusively to fields and dumps, all other species flew mainly to saltmarsh habitat. In addition, habitats were selected in relation to tidal depth and it appears, at least for the Great Egret, that low tide habitats were preferred.
