The editor’s selection is the thing through Christianson et al.: “Estimating true density in massive, alpine herbivores the use of Google Earth imagery”
Dependable estimates of inhabitants measurement and density are crucial for each analysis and control, but very tricky to succeed in. That is in particular true for wide-ranging species in far off, hard-to-access spaces. On this paper, Christianson et al. describe a easy and cost-effective strategy to estimate abundance of enormous, conspicuous mammals in open habitats the use of freely to be had Google Earth satellite tv for pc imagery. They used an unbiased double-observer protocol to estimate elk Cervus elaphus density in Yellowstone Nationwide Park, USA.
Whilst Yellowstone elk had been the topic of a large number of research, density estimates had been restricted to their extra available, lower-elevation wintry weather vary; the far off and huge Alpine summer season vary on the other hand that had by no means been systematically surveyed. Identical survey protocols may well be helpful additionally for different massive species, particularly when top detectability within the open lets in for prime precision of density estimates, as was once the case for Yellowstone elk.
