摘要:
‘information providers’ as cues for high-quality habitat. This constitutes what we term an ‘information-mediated Allee effect’. We present the fir

摘要:
e is a sharp transition around a specific threshold population size. In the ecological literature, such threshold phenomena are called “strong Allee effect

A small or sparse population may suffer a reduction in fitness due to Allee effects. Here we explored effects of plant density on pollination
