Recent distribution and status of nesting bald eagles in Baja California, Mexico Recent distribution and status of nesting bald eagles in Baja California, Mexico
We studied Bald Eagles(Haliaeetus leucocephalus) nesting in Baja California, Mexico, and vicinity from 1983-1993. The range of nesting Bald Eagles in Baja California has been reduced from a scattering of pairs along both the Pacific and Gulf sides to a remnant population in Magdalena Bay where no more than three pairs were found annually. Low numbers and a restricted distribution make...

Capture-recapture studies for multiple strata including non-markovian transitions Capture-recapture studies for multiple strata including non-markovian transitions
We consider capture-recapture studies where release and recapture data are available from each of a number of strata on every capture occasion. Strata may, for example, be geographic locations or physiological states. Movement of animals among strata occurs with unknown probabilities, and estimation of these unknown transition probabilities is the objective. We describe a computer...

Effects of acidification on metal accumulation by aquatic plants and invertebrates. 2. Wetlands, ponds and small lakes Effects of acidification on metal accumulation by aquatic plants and invertebrates. 2. Wetlands, ponds and small lakes
Compared were concentrations of Al, Cd, Ca, Cu, Fe, Pb, Mg, Mn, Hg, Ni, P, and Zn in water, plants, and aquatic invertebrates of wetlands, ponds, and small lakes in Maryland and Maine. The accumulation of metals by aquatic plants and insects and the concentration of metals in water were not greatly affected by pH. None of the metal concentrations in water significantly correlated with...

Point counts of landbirds in bottomland hardwood forests of the Mississippi Alluvial Valley: How long and how many? Point counts of landbirds in bottomland hardwood forests of the Mississippi Alluvial Valley: How long and how many?
To quantify efficacy of point count sampling in bottomland hardwood forests, we examined the influence of point count duration on corresponding estimates of number of individuals and species recorded. To accomplish this we conducted a totalof 82 point counts 7 May-16 May 1992distributed among three habitats (Wet, Mesic, Dry) in each of three regions within the lower Mississippi Alluvial...
