Movements and mortality of common Bucephala clangula broods in a patchy environment

Article Abstract:

The effects of habitat configuration on movements, space use and mortality of individuals are studied in a naturally patchy environment using radio-marked common goldeneye, Bucephala clangula females with their broods. The analysis has suggested that species living in naturally patchy environment might have evolved remarkable skills to successfully cross an inhospitable matrix when changing patches.

Within-season sequential density dependence regulates breeding success in mallards Anas platyrhynchos

Article Abstract:

A study is conducted on the breeding success, lake use, and prey availability in wild mallards Anas platyrhynchos on small nemoral lakes in a replicated, two-year crossover experiment in which pair density was increased. It is concluded that using a single and late measure of breeding success such as fledged birds could mask regulatory processes.

Dynamics of habitat distribution in breeding mallards: assessing the applicability of current habitat selection models

Article Abstract:

The article examines ideal despotic, ideal free and ideal preemptive habitat selection models for depicting habitat selection among breeding mallards. Research indicates that rich habitats became increasingly crowded, while proportional use decreased for poor habitats. None of the three models listed explains these findings.
