Modeling interpopulation dispersal by banner-tailed kangaroo rats Modeling interpopulation dispersal by banner-tailed kangaroo rats
Many metapopulation models assume rules of population connectivity that are implicitly based on what we know about within-population dispersal, but especially for vertebrates, few data exist to assess whether interpopulation dispersal is just within-population dispersal "scaled up." We extended existing multi-stratum mark-release-recapture models to incorporate the robust design...

Evolution of quantitative methods for the study and management of avian populations: on the importance of individual contributions Evolution of quantitative methods for the study and management of avian populations: on the importance of individual contributions
The EURING meetings and the scientists who have attended them have contributed substantially to the growth of knowledge in the field of estimating parameters of animal populations. The contributions of David R. Anderson to process modeling, parameter estimation and decision analysis are briefly reviewed. Metrics are considered for assessing individual contributions to a field of inquiry...

Spring hunting changes the regional movements of migrating greater snow geese Spring hunting changes the regional movements of migrating greater snow geese
1. Human-induced disturbance such as hunting may influence the migratory behaviour of long-distance migrants. In 1999 and 2000 a spring hunt of greater snow geese Anser caerulescens atlanticus occurred for the first time in North America since 1916, aimed at stopping population growth to protect natural habitats. 2. We evaluated the impact of this hunt on the staging movements of geese...

Temporal variability of local abundance, sex ratio and activity in the Sardinian chalk hill blue butterfly Temporal variability of local abundance, sex ratio and activity in the Sardinian chalk hill blue butterfly
When capturing and marking of individuals is possible, the application of newly developed capture-recapture models can remove several sources of bias in the estimation of population parameters such as local abundance and sex ratio. For example, observation of distorted sex ratios in counts or captures can reflect either different abundances of the sexes or different sex-specific capture
