Female age and egg size in the Lesser Snow Goose
younger birds laying slightly smaller eggs in each position within the laying sequence. Some physiological maturation process was probably responsible for the smaller eggs younger birds laid because the pattern held within individuals. However, changes in egg size and shape may be due to breeding experience rather than age itself. We detected no evidence for age-specific differences in egg size...
متن کاملRetrospective Analysis of Demographic Responses to Environmental Change: A Lesser Snow Goose Example
In general, analysis of population dynamics can proceed either prospectively or retrospectively. In the case of the former, asymptotic expectations are generally derived (analytically or numerically) from analysis of the potential effects of perturbation of the elements of the life table. However, the vital rates that are indicated by prospective analysis to contribute the most to projected gro...
متن کاملPasteurella multocida serotype 1 isolated from a lesser snow goose: evidence of a carrier state.
Pharyngeal swabs were collected from 298 lesser snow geese (Chen caerulescens caerulescens) at Banks Island (Northwest Territories. Canada) in the summer of 1994. Pasteurella multocida serotype 1 was isolated from an adult male bird and P. multocida serotype 3 was isolated from an adult female goose. Pathogenicity of the serotype 1 isolate was confirmed by inoculation in Pekin ducks (Anas platy...
متن کاملEstimation of trade-offs with capture± recapture models: a case study on the lesser snow goose
Trade-offs between traits such as fecundity or survival are fundamental to much of our understanding of the evolution of life histories. There has been much renewed interest and controversy concerning methods for estimating trade-offs, in the wild or in captivity, and with or without experimental manipulations. In this paper, we assess the general question of the utility of modern capture ± rec...
متن کاملEffects of exploitation on an overabundant species: the lesser snow goose predicament.
Invasive and overabundant species are an increasing threat to biodiversity and ecosystem functioning world-wide. As such, large amounts of money are spent each year on attempts to control them. These efforts can, however, be thwarted if exploitation is compensated demographically or if populations simply become too numerous for management to elicit an effective and rapid functional response. We...
