High genetic diversity but spatially restricted genetic connectivity in a Tropical Montane Cloud Forest tree (Magnolia schiedeana)
Magnolias are representative shrub and tree species of the Tropical Montane Cloud Forest (TMCF) in Mexico, which is one of the most endangered ecosystems due to anthropogenic landscape degradation and climate change. Magnolia schiedeana is a vulnerable and restricted endemic TMCF species, occurring in scattered TMCF fragments in the Sierra Madre Oriental. In this study, we investigated spatial patterns of genetic diversity across the M. schiedeana species range and assessed whether gene flow was influenced by topographic and environmental factors. We sampled eleven remnant populations across the species range and genotyped 180 individuals at eight nuclear microsatellite loci. Our data showed a strong spatial structure in five genetic clusters, which match the patchy geographic distribution of M. schiedeana. Contemporary migration rates between these genetic clusters were very low. Levels of genetic diversity within populations were moderate to high, and no evidence of inbreeding was found. Our results from landscape genetic analysis showed that isolation by distance, rather than topography or environmental variation, was the main process shaping genetic differentiation. Urgent actions are needed to protect M. schiedeana populations as most of them persist isolated within agricultural and urban landscapes. Ex-situ management actions would be crucial to ensure the conservation of genetically diverse germplasm for the in-situ propagation where it has gone locally extinct.

Direct and indirect effects of environmental factors, spatial constraints, and functional traits on shaping the plant diversity of montane forests
Understanding the relative importance of the factors driving the patterns of biodiversity is a key research topic in community ecology and biogeography. However, the main drivers of plant species diversity in montane forests are still not clear. In addition, most existing studies make no distinction between direct and indirect effects of environmental factors, spatial constraints on plant biodiversity. Using data from 107 montane forest plots in Sichuan Giant Panda habitat, China, we quantified the direct and indirect effects of abiotic environmental factors, spatial constraints, and plant functional traits on plant community diversity. Our results showed significant correlations between abiotic environmental factors and trees (r = 0.10, P value = 0.001), shrubs (r = 0.19, P value = 0.001), or overall plant diversity (r = 0.18, P value = 0.001) in montane forests. Spatial constraints also showed significant correlations with trees, and shrubs. However, no significant correlations were found between functional traits and plant community diversity. Moreover, the diversity (richness and abundance) of shrubs, trees, and plant communities was directly affected by precipitation, latitude, and altitude. Mean annual temperature (MAT) had no direct effect on the richness of tree and plant communities. Further, MAT and precipitation indirectly affected plant communities via the tree canopy. The results revealed a stronger direct effect on montane plant diversity than indirect effect, suggesting that single-species models may be adequate for forecasting the impacts of climate factors in these communities. The shifting of tree canopy coverage might be a potential indicator for trends of plant diversity under climate change.
