Both road mortality and the barrier effect caused population isolation.
In both experiments, there were no effects of population isolation.
We suggest that landscape analyses can serve as a proxy for population isolation in ambystomatid salamanders.
If certain landcover types consistently act as barriers to movement, their occurrence could serve as a proxy for population isolation.
In all cases, agriculture was associated with increased population isolation, while deciduous forest was almost always associated with decreased isolation.
Importantly, these markers can demonstrate key attributes of breeding systems, such as gene flow and the level of population isolation, factors which correlate with fitness and evolutionary potential60.
A diachronic approach, comparing distribution before and after the linear infrastructure is constructed, leads to the design of a species distribution assessment (SDA), taking into account population isolation.
I have used a common annual to examine how population isolation may affect reproductive success and ultimately population growth and persistence.
The low dispersal capacity of sand flies could lead to population isolation due to geographic barriers, climate variation, or to population fragmentation associated with specific local habitats due to landscape modification.
Plant species will be influenced mostly by the responses of their pollinators and herbivores to changes in population isolation, making it hard to predict how habitat fragmentation may affect a plant species.
For each Natura 2000 site a calculation was made of the conservation value of each species, together with an assessment of population isolation in relation to natural range and global conservation value.
