Trends in weather conditions favor generalist over specialist species in rear-edge alpine bird communities
<p>Using the community of six passerine species breeding in the alpine zone of the Cantabrian mountains (NW Iberian Peninsula), we sought to document the changes in bird abundance across the elevational gradient during the last decade, evaluate the relationship between bird abundance and local climatic conditions (i.e. weather conditions), and discuss the mechanisms by which these conditions might be mediating the observed abundance trends in a global warming context. We estimated bird abundance at the home range level using point count transects and distance sampling during the breeding season, and fitted generalized linear mixed models to describe their temporal trends across the elevational gradient. We used a structural equation modeling approach to estimate the direct, indirect and total effects of weather and temporal variables, while considering the correlations and causal relationships among them and with the elevational gradient.</p>

The evolution of hummock-depression micro-topography in an alpine marshy wetland in Sanjiangyuan as inferred from vegetation and soil characteristics
The hummock-depression micro-topography characteristics of the alpine marshy wetland in Sanjiangyuan are indicative of wetland degradation and the process by which healthy wetlands are transformed into flat grasslands. The aim of the present study was to examine changes in plant community structure and soil characteristics in a hummock-depression micro-topography along a degradation gradient. We observed that: (1) the height and cover of dominant hydrophytes decreased gradually with an increase in degradation severity, leading to replacement by xerophytes; (2) with the transition from healthy to degraded wetlands, hummocks became sparser, shorter, and broader and became merged with nearby depressions; water reserves in the depressions shifted from perennial to seasonal, until they dried out completely; (3) soil moisture content, porosity, hardness, and organic matter gradually decreased by 30.61%, 19.06%, 37.04%, and 73.27%, respectively, in hummocks and by 33.25%, 8.19%, 47.72%, and 76.79%, respectively, in depressions. Soil bulk density, soil electrical conductivity, and soil dry weight increased by 31%, 83.33%, and 105.44%, respectively, in hummocks, but by only 11.93%, 7.14%, and 97.72%, respectively, in depressions. The results show that hummock soils in healthy wetlands have strong water absorption properties, through which plant roots can penetrate easily. Wetland degradation reduces the water absorption capacity of hummock soil and soil saturation capacity of depressions, thus enhancing soil erosion potential and susceptibility to external factors. Soil moisture is a key environmental factor influencing wetland degradation, and grazing accelerates the process. Based on the changes observed in hummock morphology, vegetation, and soil properties along a degradation gradient, a conceptual model is proposed to illustrate the process of gradual degradation of marshy wetlands from healthy to transitional wetlands and finally to a degenerated state. Thus, our research provides insights into the degradation process of the alpine marshy wetland ecosystem in Sanjiangyuan.

Can functional genomic diversity provide novel insights into mechanisms of community assembly? A pilot-study from an invaded alpine streambed
<p>An important focus of community ecology, including invasion biology, is to investigate functional trait diversity patterns to disentangle the effects of environmental and biotic interactions. However, a notable limitation is that studies usually rely on a small and easy to measure set of functional traits, which might not immediately reflect ongoing ecological responses to changing abiotic or biotic conditions, including those that occur at a molecular or physiological level. We explored the potential of using the diversity of expressed genes—functional genomic diversity (FGD)—to understand ecological dynamics of a recent and ongoing alpine invasion. We quantified FGD based on transcriptome data measured for 26 plant species occurring along adjacent invaded and pristine streambeds. We used an RNA-seq approach to summarize the overall number of expressed transcripts and their annotations to functional categories, and contrasted this with functional trait diversity (FTD) measured from a suite of characters that have been traditionally considered in plant ecology. We found greater FGD and FTD in the invaded community, independent of differences in species richness. However, the magnitude of functional dispersion was greater from the perspective of FGD than from FTD. Comparing FGD between congeneric alien-native species pairs, we did not find many significant differences in the proportion of genes whose annotations matched functional categories. Still, native species with a greater relative abundance in the invaded community compared with the pristine tended to express a greater fraction of genes at significant levels in the invaded community, suggesting that changes in FGD may relate to shifts in community composition. Comparisons of diversity patterns from the community- to the species-level offer complementary insights into processes and mechanisms driving invasion dynamics. FGD has the potential to illuminate cryptic changes in ecological diversity, and we foresee promising avenues for future extensions across taxonomic levels and macro-ecosystems. </p>
Drivers of intraspecific differentiation of the alpine cold tolerant herb Notopterygium oviforme: the roles of isolation by distance and ecological factors
<p>Determining the driver mechanisms of phenotypic and genetic divergence of species have long been the central topic in evolutionary biology. However, the relative roles of isolation by distance (IBD) and environment factors in contributing to species divergence is largely undetermined in perennial herbs in East Asia. In this study, we collected population genetic samples of a cold-tolerant perennial herb <i>Notopterygium oviforme</i> in central China. We integrated the population transcriptomes, whole chloroplast genomes, genotyping-by-sequencing, microsatellite markers and ecological environment factors to determine the relative contributions of geography, climatic and soil factors on genetic, chemical and phenotypic trait divergence. The clearly genetic distinction was identified between the west Qinling (WQ) and east Qinling Mountains (EQ) geographical groups within<i> N. oviforme</i>. Interestingly, the two groups have existed the obviously niche conservatism, which might have caused the similarity of most leaf functional traits. Multiple matrix regression with randomization analysis showed that the spatial pattern of intraspecific divergence mainly resulted from effect of IBD, not isolation by environment. Meanwhile, transcriptomic expression divergence and some ecological factors have played the key roles in differentiation of intraspecific lineage. Approximate Bayesian Computation showed that both lineages have experienced the historically population expansion, and the recent range contraction. Molecular dating suggested that the intraspecific divergence was closely associated with the dramatically uplifts of the Qinling Mountains in East Asia. These results demonstrated that the geography, geological and environmental factors together shaped the cryptic intraspecific diversification and population dynamics shifts of<i> </i>perennial cold tolerant herb.</p>
