Demography, environmental uncertainty, and the evolution of mate desertion in the snail kite Demography, environmental uncertainty, and the evolution of mate desertion in the snail kite

The Snail Kite (Rostrhamus sociabilis), an endangered hawk, has a unique mating system in Florida (Beissinger and Snyder 1987): when food is abundant, males or females desert their mates at nearly equal frequency (ambisexual mate desertion) in the midst of a nesting cycle. I examined the demographic and environmental constraints selecting for a clutch size that permits one parent to...

Reproductive toxicity of monocrotophos to bobwhite quail Reproductive toxicity of monocrotophos to bobwhite quail

Pairs of 1st-year breeding bobwhites were fed constant or decreasing concentrations of monocrotophos for 15 days. In addition, a control diet was used in a pair-fed group matched with the pairs in the constant group. Dietary concentrations for the constant group were logarithmically spaced at .100, .178, .316, .562, 1.000 ppm of actual insecticide and also at 0 ppm (control) for five...

Wolf population in the Central Superior National Forest, 1967-1985 Wolf population in the Central Superior National Forest, 1967-1985

Since winter 1977-1978, the population has remained relatively stable because an increasing proportion of it has switched to preying on moose. The number of wolves preying on...

Selenium and heavy metals in San Francisco Bay diving ducks Selenium and heavy metals in San Francisco Bay diving ducks

We analyzed for selenium (Se) and heavy metals in greater scaups (Aythya marila) and surf scoters (Melanitta perspicillata) collected from southern San Francisco Bay in March and April 1982. There were no differences (P > 0.05) between species for liver concentrations of silver (Ag), mercury (Hg), or lead (Pb). Copper (Cu) (P 0.001) and zinc (Zn) (P 0.01) levels were higher in scaups...
