Sentence examples for edge population from inspiring English sources
As important indicators, distance from edge, population, structure and diversity determined for establishing models can be applied to measure the intensity of edge effects and decide the positive or negative impact on communities.
At the edge, population sizes are usually lower and the match between the plant's adaptations and the environments are usually less good than in the main portion of the species' range (e.g. Eckert et al. 2008).
However, when approaching the trailing edge, population densities gradually grow and increase competition, thereby benefiting lineages consisting of shorter dispersal distance genotypes.
The differentiation of edge populations along the coast is associated with precipitation seasonality.
Monitoring "trailing edge" populations of rare species should be a high conservation priority to support decision-making related to assisted colonization.
In their recent network study on beech, highest sensitivity and low resistance to drought is namely reported in the core of the species range, while dry range edge populations were characterized by particularly high drought resistance.
Extinction of southern edge populations along the Iberian Peninsula has been reported for other marine cold temperate species [ 17].
Spatial sorting increases the frequency of dispersive genotypes near the expanding range edges based on the standing variation in populations rather than by mutations in the edge populations.
These meta-population dynamics varied across the geographical range examined with edge populations exhibiting lower genetic diversities and higher rates of population expansion than more central populations.
For example, along Atlantic European shores, southern edge populations of F. serratus are less resilient to desiccation and heat shock than central populations [ 49].
In this example, gene flow from central to peripheral populations was maladaptive, while gene flow between edge populations increased fitness (Sexton et al. 2011).
