In this study, we focused on the bedrock-dependent effects of climate change terricolous lichen communities along elevational gradients in Alps. particular, contrasted between carbonatic and siliceous bedrock, hypothesizing more favourable conditions than where dryer may exacerbate change. To test hypothesis, compared diversity patterns two bedrock types terms (1) species richness, (2) beta-diversity, (3) proportion cryophilous species, (4) functional diversity, also testing effect gradient as a proxy for expected warming. Our results indicate that most cold-adapted part terricolus biota Alps could be especially threatened near future, mainly bedrock. Actually, contrasting were found clearly revealing lichens As hypothesized, hosts richer reflecting general richness pattern at national level. general, seems to less prone rapid pauperization its biota, providing suitable climatic refugia can mitigate warming lichens.

Climate and Bedrock Collectively Influence the Diversity Pattern of Plant Communities in Qiniangshan Mountain

Climate and geological diversity have been proven to make an important contribution biodiversity. Volcanic ecosystems often a long history diverse bedrock, thus shaping variety of habitats. Understanding the relative importance role contemporary climate bedrock environment in volcanic biodiversity still needs further exploration. To address this knowledge gap, we investigated patterns plant phylogenetic structure at community level Qiniangshan Mountain, while also exploring relationship between regional environmental factors (e.g., types). In Mountain communities, species richness is higher mid-to-high elevations. Montane communities exhibit compared coastal communities. There are significant differences among on different with highest found pyroclastic lava. Bedrock, along related energy precipitation, collectively influence The Net Relatedness Index (NRI) influenced by aspects, Nearest Taxon (NTI) affected both factors. Phylogenetic Diversity (PDI) primarily within Mountain’s These findings highlight profound impact montane vegetation

Topography has an important influence on plant–soil relationships. However, research relationships in alpine grassland at the slope aspect and position scales is currently inadequate. In this paper, based topographic geomorphological characteristics of study area, with typical conditions was selected as object. Through field investigations laboratory to reveal how plant community soil factors respond changes topography. The results show: Slope significantly affect communities properties. terms dominant species communities, sunny slopes were dominated by Poaceae shady Polygonaceae. Plant characterization variables showed a decreasing trend from bottom top. significant differences among six types topography (p < 0.05), magnitude order different aspects positions basically > middle Correlation analysis that there good correlations between organic carbon (SOC), water content (SWC), total nitrogen (TN), pH, grassland. addition, redundancy analyses (RDA) indicated divergence primarily driven change difference SOC along gradients. Our findings may provide scientific basis for restoration utilization vegetation evaluation ecological environment region.
