Data from: Significant genetic boundaries and spatial dynamics of giant pandas occupying fragmented habitat across southwest China
Understanding population history and genetic structure are key drivers of ecological research. Here we studied two highly fragmented and isolated populations (Xiaoxiangling and Daxiangling) of giant pandas (Ailuropoda melanoleuca) at the extreme southwestern edge of their distribution. This area also contains the Dadu River, national road 108 and various human infrastructure and development, providing an ideal region in which we can identify the effects of different barriers on animal movements. We used partial mitochondrial control region (mtDNA) and nine microsatellite loci (nuclear DNA) data derived from 192 fecal and one blood sample collected from the wild. We found 136 genotypes corresponding to 53 unique multilocus genotypes and eight unique control region haplotypes (653 bp). Significant genetic boundaries correlated spatially with the Dadu River (K=2). We estimate that a major divergence took place between these populations 26 000 YBP, at around the similar time the rock surface of valley bottom formed in Dadu River. The national road has resulted in further recent population differentiation (Pairwise FS on mtDNA and nuclear DNA) so that in effect, four smaller sub-populations now exist. Promisingly, we identified two possible first generation migrants and their migration paths, and recommended the immediate construction of a number of corridors. Fortunately, the Chinese government has accepted our advice and is now planning corridor construction.
Data from: Population genetics reveals high connectivity of giant panda populations across human disturbance features in key nature reserve
The giant panda is an example of a species that has faced extensive historical habitat fragmentation and anthropogenic disturbance, and is assumed to be isolated in numerous subpopulations with limited gene flow between them. To investigate the population size, health and connectivity of pandas in a key habitat area, we noninvasively collected a total of 539 fresh wild giant panda fecal samples for DNA extraction within Wolong Nature Reserve, Sichuan, China. Seven validated tetra-microsatellite markers were used to analyze each sample, and a total of 142 unique genotypes were identified. Non-spatial and spatial capture-recapture models estimated the population size of the reserve at 164 and 137 individuals (95% confidence intervals 153-175 and 115-163), respectively. Relatively high levels of genetic variation and low levels of inbreeding were estimated, indicating adequate genetic diversity. Surprisingly, no significant genetic boundaries were found within the population despite the national road G350 that bisects the reserve, which is also bordered with patches of development and agricultural land. We attribute this to high rates of migration, with 4 giant panda road-crossing events confirmed within a year based on repeated captures of individuals. This likely means that giant panda populations within mountain ranges are better connected than previously thought. Increased development and tourism traffic in the area and throughout the current panda distribution poses a threat of increasing population isolation, however. Maintaining and restoring adequate habitat corridors for dispersal is thus a vital step for preserving the levels of gene flow seen in our analysis and the continued conservation of the giant panda meta-population in both Wolong and throughout their current range.

Data from: Plant diversity in giant panda habitat
<p>Understanding the relative importance of the factors driving the patterns of biodi-<br> versity is a key research topic in community ecology and biogeography. However, the <br> main drivers of plant species diversity in montane forests are still not clear. In addi-<br> tion, most existing studies make no distinction between direct and indirect effects of <br> environmental factors and spatial constraints on plant biodiversity. Using data from <br> 107 montane forest plots in Sichuan Giant Panda habitat, China, we quantified the <br> direct and indirect effects of abiotic environmental factors, spatial constraints, and <br> plant functional traits on plant community diversity. Our results showed significant <br> correlations between abiotic environmental factors and trees (r = .10, p value = .001), <br> shrubs (r = .19, p value = .001), or overall plant diversity (r = .18, p value = .001) in mon-<br> tane forests. Spatial constraints also showed significant correlations with trees and <br> shrubs. However, no significant correlations were found between functional traits <br> and plant community diversity. Moreover, the diversity (richness and abundance) of <br> shrubs, trees, and plant communities was directly affected by precipitation, latitude, <br> and altitude. Mean annual temperature (MAT) had no direct effect on the richness of <br> tree and plant communities. Further, MAT and precipitation indirectly affected plant <br> communities via the tree canopy. The results revealed a stronger direct effect on <br> montane plant diversity than indirect effect, suggesting that single-species models <br> may be adequate for forecasting the impacts of climate factors in these communities. <br> The shifting of tree canopy coverage might be a potential indicator for trends of plant <br> diversity under climate change.</p>
