- Specialized
- The researchers identified distinct demes within the species, each showing unique genetic markers.
Examples
-
The raw detections were clustered into 238 sites, constituting 31 demes in 15 mountain ranges and distinct geographic areas (Fig. 2).
Academic text (2017) -
Delineation of possible demes in our survey area provided insight into the potential for connectivity and allowed a better understanding of the importance of a "patch"-sized scale in determining area occupancy.
Academic text (2017) -
We present our results by occupancy status and at multiple scales, including site, deme, and mountain range.
Academic text (2017) -
These demes are meant to present a snapshot of potentially connected populations.
Academic text (2017) -
Overall, the occupied demes were found more in the western part of our study area (Fig. 2).
Academic text (2017) -
We acknowledge that because we were unable to survey all potential habitats in every area, not every currently occupied and relict site was detected in our survey effort, and this lack of data may artificially cause some demes to appear disjunct.
Academic text (2017) -
Here, we document numerous pika sites over a 2-year survey period and present our results at multiple scales, from the smaller "site" level to a snapshot of potentially connected population centers (or "demes") to larger mountain ranges.
Academic text (2017) -
Our surveys indicate that the extant Boulder Canyon and Grassy Canyon demes may once have been connected via the Pinto Peak deme, but this area is now likely extirpated.
Academic text (2017) -
Furthermore, the relict Black Rock demes (Fig. 9) were likely at one point connected to each other and possibly to the early 20th-century occupied Pine Forest Range to the north and the currently occupied Sheldon NWR to the west.
Academic text (2017) -
It is also possible that the Boulder Canyon deme was once connected throughout the Hays Canyon Range north to the Carter Reservoir deme, but surveys that documented relict demes in between, such as at Forty-niner Mountain, suggest another possible and recent break in connectivity.

Etymology
Deme comes from the Greek root demos, which means 'people' and is the same root in democracy. In ancient Greece a deme was a local group of people, and in biology a deme is a local population that mostly breeds within itself, so the word keeps the idea of a local community.
