Spatial heterogeneity in the effects of climate and density-dependence on dispersal in a house sparrow metapopulation.
Dispersal plays a key role in the response of populations to climate change and habitat fragmentation. Here, we use data from a long-term metapopulation study of a non-migratory bird, the house sparrow (Passer domesticus), to examine the influence of increasing spring temperature and density-dependence on natal dispersal rates and how these relationships depend on spatial variation in habitat q...

متن کاملGeographic Variation in Wing-loading of the House Sparrow
Intraspecific variation in size of widely distributed birds often agrees with modern interpretation of Bergmann’ s Rule; that is, size is correlated with a combination of climatic variables that includes temperature and/or moisture (James 1968, 1970, Power 1969). N or th ern races of birds are frequently larger (Mayr 1963:320), but the adaptive significance of increased size has been widely deb...
متن کاملSpatial Segregation in Demography: A Short Review
Abstract. Spatial has always been an inherent component of demography, and demographic processes are inherently spatiotemporal. Recognizing the importance of spatial in general and spatial segregation in particular in demographic analysis has created new positions in demography and its conceptual and analytical frameworks. The notion of spatial segregation refers to the distribution of social...
متن کاملMultilocus heterozygosity and inbreeding depression in an insular house sparrow metapopulation.
Inbreeding causes reduction of genetic variability that may have severe fitness consequences. In spite of its potentially huge impact on viability and evolutionary processes especially in small populations, quantitative demonstrations of genetic and demographic effects of inbreeding in natural populations are few. Here, we examine the relationship between individual inbreeding coefficients (F) ...
