Ecological theory of alternative stable communities suggests the switch between different species assemblages occurs when environmental conditions alter species composition so that it crosses a critical threshold and enters a different basin of attrac . . .

Long-lived species of large size can play critical roles as ecosystem engineers but the demography of early life stages is poorly known for many such species. For example, the fucoid alga, Ascophyllum nodosum, serves as the foundation species for many . . .

Few studies have surveyed the insects visiting flowers at many sites and for many related species. Calochortus, a genus of about 60 species with its center of diversity in California, has flowers with a wide range of appearances. Insects visiting Calo . . .

We investigated the effect of local environment on the demography and population dynamics of arctic ground squirrels (Spermophilus parryii plesius) by comparing reproduction, survival, and population trends of squirrels living in low elevation boreal . . .

We evaluated the predictive power of two classification techniques, one parametric - discriminant function analysis (DFA) and the other non?parametric - classification and regression tree analysis (CART), in order to provide a non?subjective quantitat . . .

As the climate warms, there is little doubt that ecosystems of the future will look different from those we see today. However, community responses to warming in the field are poorly understood. We examined the effects of field‐based warming on intert . . .

The seeming ubiquity of spatio?temporal variation in pollination regime suggests that flowers ought to be adapted to a wide range of pollinators, yet many comparative biologists perceive that in groups with complex flowers there is considerable specia . . .
