Estimating breeding proportions and testing hypotheses about costs of reproduction with capture-recapture data Estimating breeding proportions and testing hypotheses about costs of reproduction with capture-recapture data
The proportion of animals in a population that breeds is an important determinant of population growth rate. Usual estimates of this quantity from field sampling data assume that the probability of appearing in the capture or count statistic is the same for animals that do and do not breed. A similar assumption is required by most existing methods used to test ecologically interesting...

The applicability of terrestrial visitor impact management strategies to the protection of coral reefs The applicability of terrestrial visitor impact management strategies to the protection of coral reefs
A dramatic expansion in nature-based tourism to tropical coastal destinations has occurred in the past 20 years. Tourism development, combined with intense recreational pressures, has irreversibly transformed and degraded many popular scenic natural environments. This paper examines the management of recreational impacts to coral reefs using Virgin Islands National Park as a case study...

Effect of subatmospheric pressure on the performance of an automated packed-column nitrogen desorption system Effect of subatmospheric pressure on the performance of an automated packed-column nitrogen desorption system
A portable vacuum degasser was developed to satisfy seasonal hatchery pretreatment needs. Dissolved-gas pressures in water exiting a packed column were regulated automatically with a unique feedback control loop incorporating a gasometer, pressure transducer, electronic (PID) controller and an electrically actuated pump discharge valve. The flow capacity of the system was 160 l/min with...

Late winter survival of female mallards in Arkansas Late winter survival of female mallards in Arkansas
Determining factors that limit winter survival of waterfowl is necessary to develop effective management plans. We radiomarked immature and adult female mallards (Anas platyrhynchos) after the 1988 and 1989 hunting seasons in eastcentral Arkansas to test whether natural mortality sources and habitat conditions during late winter limit seasonal survival. We used data from 92 females to...

Isolation of Aeromonas salmonicida from paddlefish, Polyodon spathula Isolation of Aeromonas salmonicida from paddlefish, Polyodon spathula
Aeromonas salmonicida was isolated from paddlefish (Polyodon spathula) mortalities collected during an epizootic of furunculosis at the Spring River State Hatchery, Arkansas (USA), in 1992. Isolates of the bacterium were obtained from culture of gill and kidney tissue. This is the first epizootic of bacterial etiology to be reported in paddlefish.
