Taxus wallichiana var. mairei; altitude; conservation genetics; deforestation; gene flow; genetic distance; genetic variation; heterozygosity; microsatellite repeats; trees; variance; China
Abstract:
... Taxus mairei (Lemée & Lév.) S.Y. Hu ex T. S. Liu is a vulnerable tree species, and it is also a precious timber species in China. We used 13 microsatellites to assess the genetic diversity and differentiation of 665 T. mairei samples from 18 natural populations. A total of 291 alleles were detected. The average number of alleles (Nₐ = 22.39), expected heterozygosity (Hₑ = 0.74), polymorphic inform ...

Abstract:
... Genome-wide evaluations of genetic diversity and population structure are important for informing management and conservation of trailing-edge populations. North American moose (Alces alces) are declining along portions of the southern edge of their range due to disease, species interactions, and marginal habitat, all of which may be exacerbated by climate change. We employed a genotyping by seque ...

Abstract:
... Establishing conservation priorities requires an understanding of the diversity within and among taxa. Land snails in the subgenus Monadenia consist of six species, three of which are recognized in Oregon, M. fidelis, M. chaceana and a recently discovered M. infumata found north of its presumed range limits in Northern California. Further, M. fidelis is composed of at least six named subspecies, o ...

Abstract:
... Genetic rescue is increasingly considered a promising and underused conservation strategy to reduce inbreeding depression and restore genetic diversity in endangered populations, but the empirical evidence supporting its application is limited to a few generations. Here we discuss on the light of theory the role of inbreeding depression arising from partially recessive deleterious mutations and of ...

Abstract:
... The tule elk (Cervus canadensis nannodes) is a California endemic subspecies that experienced an extreme bottleneck (potentially two individuals) in the mid-1800s. Through active management, including reintroductions, the subspecies has grown to approximately 6000 individuals spread across 22 recognized populations. The populations tend to be localized and separated by unoccupied intervening habit ...

Abstract:
... Special conservation efforts should be made for relict species, as they usually have small population sizes and restricted distributions, placing them in critical extinction risk. To achieve conservation, information about genetic diversity distribution is needed. Here, using nine nuclear microsatellites, we analyzed 23 populations of five recently described species of Magnolia distributed in Mexi ...

However, illuminating the processes influencing functional connectivity and ultimately translating this knowledge into management practice remains a fundamental challenge.

Abstract:
... Population sizes of endemic songbirds on Kaua‘i have decreased by an order of magnitude over the past 10–15 years to dangerously low numbers. The primary cause appears to be the ascent of invasive mosquitoes and Plasmodium relictum, the agent of avian malaria, into elevations formerly free of introduced malarial parasites and their vectors. Given that these declines in native bird populations appe ...
