Dans Bird Study (46(Suppl.) 1999)

To investigate potential biases in productivity indices and survival-rate estimates from four years(1992-95) of data from the Monitoring Avian Productivity and Survivorship (MAPS) Programme, we examined correlations and regressions of trends in [...]

Identifying the proximate demographic cause(s) of population change by modelling spatial variation in productivity, survivorship, and population trends

Dans Ardea (89(1) 2001)

A technique for identifying the proximate demographic cause(s) of population decline at two spatial scales is proposed and evaluated. The approach involves modelling spatial variation in vital rates (productivity and survivorship) as a function [...]
