There is usually a discrepancy between the spatial scale at which statistical climate niche modelling is performed (e.g. grids of 10, 2.5 or 0.5 arc-minutes for the popular WorldClim data layers) and the spatial scale of genetic sampling for phylogeographic studies (usually several tens or hundreds of kilometres between sampling sites).
This genetic sampling can cause queasiness among contemporary readers.
Genetic drift, also called genetic sampling error or Sewall Wright effect, a change in the gene pool of a small population that takes place strictly by chance.
It is our hope that increased genetic sampling (from specimen and blood collection in the field), in combination with our foraging and behavioral observations, will reveal why this endemic montane white-eye was able to speciate in such close geographic proximity to the lowland species.
Non-invasive genetic sampling (NGS) is being increasingly applied in wildlife monitoring and population genetic research.
Considering the constant improvement of noninvasive genetic sampling techniques, the importance of search-encounter methods for population monitoring is bound to increase.
A total of 19 migration events were detected by genetic first-generation assignment tests (11), by unintentional repeated genetic sampling of individuals (6) and by radio-tracking between predefined populations (2).
We carried out systematic non-invasive genetic sampling using hair traps on power poles, as part of a capture-mark-recapture study design in order to rigorously estimate abundance and density of the Pindos bear population in Greece.
During 2007 2010 a systematic non-invasive genetic sampling effort was carried out to determine the spatial distribution and to estimate the population size of an endangered otter population in northern Iberian Peninsula (Basque Country).
In order to assess population size, sex ratio, age structure, and levels of genetic variation, we carried out non-invasive genetic sampling, using elephant dung as the source of DNA.
With the advent of alternate survey methods and platforms within the marine environment (e.g. satellite telemetry, passive acoustics, photo identification, nesting site monitoring and genetic sampling) in addition to traditional shipboard or aerial visual surveys, researchers have been developing novel analytical and modeling methodologies to fulfill such in-depth ecological assessments.
