Potential Impacts of Climatic Change on European Breeding Birds
BACKGROUND Climatic change is expected to lead to changes in species' geographical ranges. Adaptation strategies for biodiversity conservation require quantitative estimates of the magnitude, direction and rates of these potential changes. Such estimates are of greatest value when they are made for large ensembles of species and for extensive (sub-continental or continental) regions. METHODOL...
متن کاملRelating Habitat and Climatic Niches in Birds
Predicting species' responses to the combined effects of habitat and climate changes has become a major challenge in ecology and conservation biology. However, the effects of climatic and habitat gradients on species distributions have generally been considered separately. Here, we explore the relationships between the habitat and thermal dimensions of the ecological niche in European common bi...
متن کاملClimatic seasonality, resource bottlenecks, and abundance of rainforest birds: implications for global climate change
We demonstrate that within-year climatic variability, particularly rainfall seasonality, is the most significant variable explaining spatial patterns of bird abundance in Australian tropical rainforest. The likely mechanism causing this pattern is a resource bottleneck (insects, nectar, and fruit) during the dry season that limits the population size of many species. The patterns support both t...
متن کاملForensic entomology and climatic change.
Forensic entomology establishes the postmortem interval (PMI) by studying cadaveric fauna. The PMI today is still largely based on tables of insect succession on human cadavers compiled in the late 19th- or mid-20th centuries. In the last few years, however, the gradual warming of the climate has been changing faunal communities by favouring the presence of thermophilous species. To demonstrate...
متن کاملIran's Climatic Change in the Holocene
Introduction Paleoclimatics studies can respond the many uncertainties about past climate change; an issue that is being studied seriously in the world but less attention has been paid in Iran. The Late Quaternary can be considered as Holocene. Holocene, which spans over 11,000 years ago; In general, it is considered as a period with relatively warm and stable climatic conditions. However, rec...
