2. Survival patterns and density-dependent processes in breeding mallards Anas platyrhynchos
Abstract : Measuring and assessing vital rates such as births and deaths are prerequisites for understanding population dynamics. Vital rates may be affected by the density of individuals, even though the importance of density dependence on population dynamics has been debated for a long time. READ MORE
