Inverse density dependence and the Allee effect
... It has recently been proposed that the high rates of group extinction observed in obligate cooperative breeders are generated by a need for a critical number of helpers, which produce an Allee effect13. As a result, a social group driven below a critical threshold would have a lower chance of recove ...

Therefore, for the same set of plant species in two contrasting habitats, we would hypothesize that plant trait variability observed across species should be congruent with differences in environments, yet variability observed within a species should differ with species because of different genetic ...
