Sentence examples for edge of their distribution from inspiring English sources

Canadian amphibians and reptiles, most of which are cold-adapted species at the northern edge of their distribution, can serve as case studies to improve modeling of population dynamics, create cogent, science-based policies, and prevent further declines of these taxa.

Rather, our results suggest that fire is far more likely to eliminate tree species populations along the trailing edge of their distribution under increasingly unfavorable climate, although some long-lived species (Douglas-fir) might persist longer in these locations with less frequent fire.

According to Cavanagh and Gibson [123], nine of these elasmobranch species may not breed in the Mediterranean, while some are rare because the Mediterranean represents the edge of their distribution ranges.

Wildfire may play a larger role in eliminating these conifer species along trailing edges of their distributions than facilitating establishment along leading edges, in part due to dispersal limitations and interspecific competition, and future populations may increasingly depend on persistence in locations unfavorable for their establishment.
