| climate change may account for the decline in british ring ouzels turdus torquatus. | 1. climate change is already affecting biodiversity, but the number of species for which reliable models relate weather and climate to demographic parameters is low. 2. we modelled the effect of temperature and rainfall on the breeding success and territory occupancy of ring ouzels turdus torquatus (l.) in northern britain, using data from a range of study areas, including one where there was a long-term decline in ring ouzel abundance. 3. timing of breeding was significantly related to meteorol ... | 2006 | 16689964 |
| characterizing demographic variation and contributions to population growth rate in a declining population. | 1. understanding how demographic variation translates into variation in population growth rate (λ) is central to understanding population dynamics. such understanding ideally requires knowledge of the mean, variance and covariance among all demographic rates, allowing the potential and realized contribution of each rate to λ to be estimated. such studies require integrated monitoring of all demographic rates across multiple years and are consequently rare, particularly in declining populations a ... | 2011 | 20825517 |
