The estimation of exchanges among populations or subpopulations The estimation of exchanges among populations or subpopulations
Capture-recapture methods for estimating rates of immigration, emigration, and movement among geographic strata are reviewed. We discuss likelihood-based estimation methods under models incorporating Markovian and non-Markovian movement. We briefly describe a computer program developed by Brownie et al. (1992) to carry out the necessary estimation and testing.

Techniques for research into woodcocks: experiences and recommendations Techniques for research into woodcocks: experiences and recommendations
We describe methods for the study of the American woodcock (Scolopax minor) at the Moosehorn National Wildlife Refuge. Described are techniques for the capture of particular age-sex cohorts during different times of the year, the aging and sexing, the evaluation of habitat components, and the estimation of population size. We describe successful and tried but rejected techniques with...

Behavior of radio-marked breeding American woodcocks Behavior of radio-marked breeding American woodcocks
During spring 1986-89, we equipped 175 male and 89 female American woodcocks (Scolopax minor) with radio transmitters. Radio-marking had little effect on behavior; within 1 day of marking, 37 of 64 (58%) displaying males were dominant and within 7 days, 138 of 157 (88%) were dominant. All females marked before nesting proceeded to nest, and marked females with broods remained with broods...

Habitat use and survival rates of wintering American woodcocks in coastal South Carolina and Georgia Habitat use and survival rates of wintering American woodcocks in coastal South Carolina and Georgia
Habitat use and survival rates of radio-marked American woodcocks (Scolopax minor) were studied during the winter in coastal South Carolina (1988-89) and Georgia (1989-90). Soon after they arrived, woodcocks were captured in mist nets or in modified shorebird traps or by nightlighting. Each bird was weighed, aged, sexed, and fitted with a 4-g radio transmitter and monitored daily until...

The reintroduction of the Andean condor into Colombia, South America: 1989-1991 The reintroduction of the Andean condor into Colombia, South America: 1989-1991
From 1989 to 1991,22 captive-reared Andean condors Vultur gryphus were released into three protected areas in the Andes of Colombia, South America. The goals of this reintroduction programme were to re-establish populations of these birds in protected habitat where the species had been extirpated, and to train local biologists in the conservation techniques necessary to recover their...

Geohydrology and water quality of the Calumet aquifer, in the vicinity of the Grand Calumet River/Indiana Harbor Canal, northwestern Indiana Geohydrology and water quality of the Calumet aquifer, in the vicinity of the Grand Calumet River/Indiana Harbor Canal, northwestern Indiana
The water-table configuration of the Calumet aquifer in the vicinity of the Grand Calumet River/Indiana Harbor Canal in Lake County, northwestern Indiana, reflects the complexity of the shallow ground-water-flow system. Large depressions in the water table in sewered areas interrupt broad ground-water divides between rivers. The aquifer/stream interactions along the Grand Calumet River/...

Enhanced immune response and protection rainbow trout to Aeromonas salmonicida bacterin following prior immersion immunostimulants Enhanced immune response and protection rainbow trout to Aeromonas salmonicida bacterin following prior immersion immunostimulants
Bathing rainbow trout for 30 min in immunostimulant solutions before a 2 min bath in Aeromonas salmonicida O antigen bacterin elevated both the nonspecific defence mechanisms and the specific immune response. Levamisole, a known T lymphocyte stimulator in mammals; QAC, a quaternary ammonium compound, and ISK a short-chain polypeptide, heightened the neutrophil oxidative activity as...
