'ecological barrier' is correct and usable in written English.
You can use it to describe any physical, chemical, or biological characteristics that prevent intermixing of two distinct ecosystems. For example, a mountain range could act as an ecological barrier between two distinct forests.
The bat communities in Alter do Chão were not strongly affected by forest fragmentation, and the savannas did not appear to act as an ecological barrier to bats.
Creating a permanent, ecological barrier between Lake Michigan and Illinois waterways would require, at a minimum, building a water treatment facility that would eliminate the possibility that any aquatic creature could move between the lake and Mississippi River watersheds.
According to clustering of landscape functions, four development zones were divided in the study area, i.e. urban assembling area, suburban grain-producing area, ecological barrier area, and rural developing area.
We compared the species composition between habitats, tested the effect of size, shape and density of trees of forested areas on the presence species and their relative frequency of captures, and investigated the savannas as an ecological barrier for the dispersion of bats.
But loss of Arctic ice is also likely eroding the ecological barrier that has previously protected beluga whales, allowing the parasite to move northward, he says.
This unsuitable habitat may act as an ecological barrier to dispersal, and further restrict gene flow between the SPB and TF.
Testing for stoichiometric constraints among invasive species is a novel challenge in invasion ecology to unravel how a successful invader tackles ecological barriers in novel ecosystems.
The proximate causes of invasion success are not well understood [8], [9] and a major challenge in invasion ecology is to understand how a successful invader deals with ecological barriers in the novel ecosystems.
Our results support the designation of baboons as highly flexible "generalists," and suggest that more fine-grained analyses (e.g., relative success in ecologically stressful years) may be necessary to detect clear signals of ecological barriers to gene flow.
Ecological barriers can guide frogs to the ecological corridor and cross the road without casualties.
The height and slope adjustment of ecological barriers were also proposed for references.
