摘要: The habitat suitability index, which reflects spatial variability in species occurrence probability, has been shown to exhibit various contrasting relationships with local demographic performances (survival, productivity) several species. One proposed explanation for these discrepancies is that the link between index and demography influenced by density-dependent, temporally variable processes. Based on survival rates of more than 3,000 nests monitored over 12 years North African Houbara Bustard, we investigated whether computed breeding range related nest throughout season, accounting variation meteorological conditions. We found relationship progressively changes along season this intra-annual consistent years. Our results support hypothesis space use occurs intra-annually biotic interactions strongly influence index–demography relationship.
