摘要:
In many eusocial Hymenoptera, a proportion of males are produced by workers. To assess the effect of male production by workers on the effective population size

摘要:
e experienced a recent reduction in population size due to sealing in the 1900s, which is expected to have resulted in increased inbreeding and a loss of genetic variati

摘要:
Allee effects are defined as a decline in per capita fitness at low population density. We hypothesized that predation reduces population size
