Sentence examples for effect of corridors from inspiring English sources

Evidence for a beneficial effect of corridors on species richness and abundance in habitat patches is mixed.

Assuming mortality independent of the season, and assuming the corridors merely increase migration rates between patches, only a very weak beneficial effect of corridors was possible in simulations.

For fixed corridor lengths, we also examined the effect of corridor width on effective population size.

At larger corridor lengths, the effect of corridor length is negligible because slightly shorter or longer corridors will still not facilitate dispersal between patches over short time periods.

We first tested the effect of corridor design on the genetic responses of the four species groups by varying corridor width and length.

For species that could disperse far distances within a single generation, the effect of corridor mortality was trivial at short distances because individuals continued to disperse between patches.

We examined the effect of corridor configuration by arranging the patches in a linear fashion such that the two middle patches were connected by two corridors and the two end patches were only connected by one corridor.

"It's a solid study," says Nick Haddad, an ecologist at North Carolina State University in Raleigh, "and it's unique in that nobody's looked at the effects of corridors on gene flow".

Such corridors have been well studied from an ecological perspective (Gilbert-Norton et al. 2010), but little work has examined the genetic effects of corridors that connect habitat patches.

Yet, to our knowledge, there are no studies that have examined the genetic effects of corridors from a community-level perspective.

The results presented here demonstrate the mitigating effects of corridors on the negative genetic effects associated with habitat fragmentation are achieved through two mechanisms: the exchange of individuals between patches and the reduction in genetic drift.
