Demographic compensation among populations: what is it, how does it arise and what are its implications?

abstract：:Many animal populations display consistent individual differences in suites of correlated behaviours. While these so called 'animal personalities' can substantially influence the ecology and evolution of populations, little is known about cross-sex correlations of behaviour and thus the potential of personality to lim...

Biotic selection can generate local adaptations that alter species interactions. Although some gene flow might be necessary to fuel local adaptation, higher gene flow ...
