Abstract Global spatial patterns of vascular plant diversity have been mapped at coarse grain based on climate‐dominated environment–diversity relationships and, where possible, finer using remote sensing. However, for grasslands with their small sizes, the limited availability vegetation plot data has caused large uncertainties in fine‐grained mapping species diversity. Here we used survey from 1,609 field sites (>4,000 plots 1 m 2 ), remotely sensed (ecosystem productivity and phenology, habitat heterogeneity, functional traits spectral diversity), abiotic (water‐ energy‐related, characterizing environment) together machine learning autoregressive models to predict map grassland richness per 100 across Mongolian Plateau 500 resolution. Combining all variables yielded a predictive accuracy 69% compared 64% or 65% alone. Among variables, showed highest power (55%) estimation, followed by phenology (48%), (48%) heterogeneity (48%). When considering autocorrelation, explained 52% 41%. Moreover, Remotely provided better prediction smaller size (<∼1,000 km), while water‐ energy‐dominated macro‐environment were most important drivers dominated effects macro‐scale (>∼1,000 km). These findings indicate that characteristics provide similar predictions richness, they offer complementary explanations broad scales.

ABSTRACT Urbanization is known to cause biotic homogenization, but the processes controlling homogenization are not well understood. Here, we analyzed microbial communities from 258 soil samples covering large landscape heterogeneity of entire Shanghai megacity. We measured urbanization intensity by incorporating habitat fragmentation, connectivity, and distance city center. determined extent which bacterial fungal community composition varied with how different assembly contributed variations. found significantly positive effects on compositional bacteria fungi, proportions generalists specialists were related homogenization. Dispersal ecological drift explained at least 60% variations, increased influences dispersal reducing specialists. Environmental variables < 28% higher led a simplified co‐occurrence network an proportion in network. These results indicate that homogenized shifting generalist specialist microbes, weak environmental selection. Therefore, conserve urban biodiversity ecosystem functioning face complex human impacts, management strategies should consider only conditions also drift, as species preferences, increase effectiveness actions.

Habitat fragmentation (Sensu lato) represents a landscape-scale process involving both habitat loss and the breaking apart of (habitat per se). In ecological studies, understanding impacts se on biodiversity remains critical challenge. While previous research has explored effects various ecosystems, significant gaps remain in our its bryophyte assemblages. To explore assemblages subtropical forests, we investigated bryophytes environments 18 fragmented forest landscapes (including 166 islands) Thousand Island Lake, China.

Abstract Understanding how human-mediated environmental change affects biodiversity is key for conserving evolvability. Because the most severe impacts are ongoing, such an understanding proving exceptionally difficult to attain. Islands natural, replicated experiments that serve as proxies habitat fragmentation and, therefore, allow us use historical changes in under Island Biogeography Theory (IBT) predict consequences of immediate anthropogenic on functional trait evolution. Rattlesnake venoms molecular phenotypes mediate interactions with prey, and diet venom complexity positively correlated. Consequently, rattlesnake investigate traits co-vary according IBT.

Using a mixed effects modeling approach, we found number congenerics, island isolation, area best predicted variability. All variables exhibited negative relationship complexity, contrary predictions Larger more congenerics reduced perhaps reflecting niche partitioning specialization. Ultimately, used synthetic eco-evolutionary framework evolution fragmented landscapes.

ABSTRACT Recent decades have witnessed substantial changes in freshwater biodiversity worldwide. Although research has shown that can be shaped by habitat diversity and human‐induced pressure, the potentials for interaction between these drivers at large spatial extents remain unclear. To address issues, we employed a spatially extensive multitrophic fish insect database from 3323 stream sites across United States, to investigate ability of modulate effect human pressure on richness abundance insects. We found evidence high levels were associated with increased insects (including whole‐assemblage individual trophic guilds). also show effects tend become positive diversity. Where is low, strongly reduces abundance, whereas reductions are attenuated Structural equation modeling revealed reduced diversity, indirectly negatively affecting These findings illustrate that, addition promoting greater biodiversity, may mitigate deleterious pressures two assemblages. Overall, our study suggests maintaining useful way protect ongoing increases pressure. However, if continue increase, this will reduce further threatening
