Optimal exploitation strategies for an animal population in a stochastic serially correlated environment
Optimal exploitation strategies were studied for an animal population in a stochastic, serially correlated environment. This is a general case and encompasses a number of important cases as simplifications. Data on the mallard (Anas platyrhynchos) were used to explore the exploitation strategies and test several hypotheses because relatively much is known concerning the life history and general

Reproductive responses of white leghorn hens to graded concentrations of mercuric chloride
White Leghorn hens were maintained on diets containing 0, 4, 12 or 36 p.p.m. Hg as HgCl2 from hatching in an effort to confirm (with a second species) our previously reported effects on Japanese quail reproduction. In the quail study both onset of laying and rate of egg production were accelerated by 16 and 32 p.p.m. Hg as HgCl2, but ferti ity was depressed. After 1 year on diets containing HgCl
