摘要:
1.Studies modelling heat transfer of bird plumage design suggest that insulative properties can be attributed to the density and structure

摘要:
ater resource availability allows higher densities rather than greater habitat specialization. These results help explain a pervasive global pattern in bird diversity on arid

摘要:
When populations grow or decline, habitat selection may change due to local density-dependent processes, such as site dependence and interference

摘要:
density dependence should be stronger than interspecific density dependence. Great tits and blue tits are two bird species that compete for food resources and nesti
