Virtually entire some level replacement turnover intensify as increases. Main Conclusions findings suggest migration allows track (‘winners’), whereas do not (‘losers’). As move upslope, lowlands become local extinction hotspots mountains harbour novel assemblages.

Leaf trait networks (LTNs) visualize the intricate linkages reflecting plant trait-functional coordination. Typical karst vegetation, developed from lithological dolomite and limestone, generally exhibits differential communities, possibly due to habitat rock exposure, soil depth, physicochemical properties variations, leading a shift variation functional linkages. However, how quality affect differentiation of leaf remains unclear. LTNs were constructed for typical limestone habitats by analyzing twenty-one woody traits across fifty-six forest subplots in mountains. The differences between compared using network parameters. association was analyzed redundancy analysis (RDA), Mantle's test, random model. LTN exhibited significantly higher edge density with lower diameter average path length when LTN. It indicates differentiation, displaying more compact architecture connectivity than network. specific phosphorus nitrogen contents LTN, as well mass carbon contributed degree closeness, serving crucial node regulating connectedness. Additionally, both correlated phosphorus, stoichiometric ratios, pH, organic carbon, depth exposure rates, showing greater relative importance. Soil dominate exhibiting habitat.

Aluminium (Al) is toxic to most plants. Nevertheless, some species accumulate Al without showing toxicity symptoms. Previous studies have evidenced in chloroplasts of Al-accumulating from the Cerrado vegetation South America. We ask whether increases carbon assimilation through enhanced apparent efficiency Rubisco. Seedlings Al-accumulator Qualea grandiflora (Vochysiaceae) were grown nutrient solution with 0, 740, and 1480 μm Al. Growth parameters, relative leaf water content, concentration organs, gas exchange carboxylation (measured A/Ci curves) evaluated for 60 days. Plants showed no root growth, necrotic roots, low rates, decreased efficiency. Al-treated plants, however, new white roots increased biomass leading higher hydration, was these Increased available accumulation plant organs. Absence compromised integrity Q. grandiflora, thus limiting hydration. No positive direct effect on Rubisco

Coexisting vegetation types in tropical landscapes can respond contrasting ways to rainfall, despite being the same climatic envelope. Understanding such heterogeneity vegetation-rainfall interactions is key for predicting how ecosystems might future environmental changes. Here we test whether temporal coupling between greenness and rainfall a good indicator of ecosystem state landscape. For this, study well-preserved landscape Brazilian Cerrado that formed by mosaics ecosystems, including savannas, dry forests gallery forests. First, correlate time-series quantify their each type. We then compare with other variables, as local-scale structural functional traits, well differences conditions which these exist. are set have distinct responsiveness rainfall. Commonly used tree cover height, do not depict marked types, particularly Dry strongest decrease during seasons, reflecting deciduousness on nutrient-richer soils. In contrast, increase season, when direct radiation peaks, likely due perennial access groundwater. Savannas less responsive more stable throughout year. Our findings suggest local abiotic contribute determining both distribution states savanna landscapes.

A strategy reduce invasions is establish communities consisting of with varied ecological strategies.

Formulating ecological restoration strategies requires accurately quantifying how climate and anthropogenic factors influence net primary production (NPP). A Carnegie-Ames-Stanford approach (CASA) model was applied to estimate China’s terrestrial NPP from 2001 2020. We adopted a random forest (RF) method identify the main driving forces for change in China. Total China increased noticeably with 24.91 Tg C/yr rate, as shown our results. The significantly mainly attributed human activities (64.29 ± 0.17%), chiefly due management projects (afforestation or other) fostered vegetation growth. drivers of variation varied different geographic regions. Climate dominated dynamic north (52.38 0.91%), where factor that restricted increase precipitation.

The Cerrado, South America's largest savanna, has acidic, nutrient‐poor soils and its native plants thrive under these conditions. However, abandoned pastures historically undergo changes in chemical properties due to interventions like liming fertilizer use. This favors invasive African grasses hinders plants, impacting restoration efforts. In a Cerrado grassland undergoing study, we tested whether soil acidification could restore conditions control invasives using 56 plots across 14 blocks. We hypothesized that decreased pH nutrient availability would reduce biomass enhance diversity. show reduced by 71%, with negatively affecting while sparing natives. Maintaining can help projects, as application favor species establishment. Soil effectiveness depends on local levels. Areas high cation content may require larger amendment quantities. Restoration strategies ecosystems should aim recovering historical growth support slow‐growing plants.
