“…Compensating immigration to Eugmo from the surrounding area may have been lower than immigration to Mustasaari or Byrkö. This possibility is supported by microsatellite data that shows low genetic variation in Eugmo (Selonen, Painter & Hanski, 2005;Lampila et al, 2009).…”

Habitat loss is the major phenomenon threatening species in the boreal forests. One example of a threatened species affected by habitat loss is the Siberian flying squirrel (Pteromys volans). We used mark-recapture data from 1992 to 2004 for 3 flying squirrel populations to estimate the demographic parameters of these populations. Average adult survival was 0.43-0.53, and probability of surviving and staying near the natal territory through the first winter was 0.23-0.30 in different populations. These values are low compared to survival estimates presented in the literature for other Sciurid species. The estimated population growth rates indicated population decline in all areas. In one of the areas, we found a decline in adult survival and population growth rate during the study. This decline was demonstrated to be linked to ongoing habitat loss due to logging. Low survival and emigration probabilities suggest that these populations are likely to be sinks. This highlights the need to ensure dispersal between the remaining patches of suitable habitat for successful conservation of this and other species associated with old-growth forests. The situation is worrisome as the studied populations are situated in an area where flying squirrel population densities have traditionally been high.

The Utah prairie dog (Cynomys parvidens), listed as threatened under the United States Endangered Species Act, was the subject of an extensive eradication program throughout its range during the 20th century. Eradication campaigns, habitat destruction/fragmentation/conversion, and epizootic outbreaks (e.g., sylvatic plague) have reduced prairie dog numbers from an estimated 95,000 individuals in the 1920s to approximately 14,000 (estimated adult spring count) today. As a result of these anthropogenic actions, the species is now found in small isolated sets of subpopulations. We characterized the levels of genetic diversity and population genetic structure using 10 neutral nuclear microsatellite loci for twelve populations (native and transplanted) representative of the three management designated “recovery units,” found in three distinct biogeographic regions, sampled across the species' range. The results indicate (1) low levels of genetic diversity within colonies (H e = 0.109–0.357; H o = 0.106‐ 0.313), (2) high levels of genetic differentiation among colonies (global F ST = 0.296), (3) very small genetic effective population sizes, and (4) evidence of genetic bottlenecks. The genetic data reveal additional subdivision such that colonies within recovery units do not form single genotype clusters consistent with recovery unit boundaries. Genotype cluster membership support historical gene flow among colonies in the easternmost West Desert Recovery Unit with the westernmost Pausaugunt colonies and among the eastern Pausaugunt colonies and the Awapa Recovery unit to the north. In order to maintain the long‐term viability of the species, there needs to be an increased focus on maintaining suitable habitat between groups of existing populations that can act as connective corridors. The location of future translocation sites should be located in areas that will maximize connectivity, leading to maintenance of genetic variation and evolutionary potential.

“…Further, the biology and occurrence of gliding squirrels was found to be affected by clear-cutting of forest or forest fragmentation (Woodworth et al 2000). It is noteworthy that the disjunctions in the habitat of gliding species beyond gliding capability epitomize barriers for the movement of the species which might lead to the disruption of population processes (Lampila et al 2009, van der Ree et al 2010, Taylor and Goldingay 2013, Soanes et al 2013. Thus, knowledge on gliding performance enables assessment of the ability of a gliding species to cross tree-canopy gaps Taylor 2009, Kambouris et al 2013) and this may lead to a management response such as the installation of tall wooden poles to enable, gap crossing (Goldingay et al 2011, Taylor andGoldingay 2013).…”
