Climate change and anthropogenic alteration of landscapes negatively impact the abundance species diversity plant animal communities worldwide. Much less is known about effects on phylogenetic community functioning. Here we use long‐term butterfly data (1980–2022) from Austrian Alps along an elevation gradient. We assessed how adjust structures functionality to increasing temperatures, these changes are linked trait expression Species decreased at low intermediate altitudes, increased high ones. Functional was lower than expected by a random model altitudes with time high, but not altitudes. Phylogenetic did show significant temporal trends altitude, Multifunctionality significantly correlated functional diversity, diversity. argue that ongoing homogenisation Alpine strongly affects species, The assessment richness alone, as provided common surveys, might give false impression state insect in course climate change. directions faunal heavily depend altitude therefore specific climatic conditions. Higher face decreasing multifunctionality despite due induced altitudinal up‐hill shifts many species. conclude studies series should include besides being focused endangerment. Red lists be extended categories importance distinctness.

Abstract Land use/cover (LULC) changes have unequivocally affected biodiversity and ecosystem functioning, with enormous repercussions for human well‐being. However, the mechanistic ecological mechanisms underlying impact of land conversion on multifunctionality (EMF) remain insufficiently examined from perspective multiple attributes in dryland regions increasing deforestation rates. We investigated how natural forests savannas to agroforestry parklands alters relationships between (taxonomic, functional, phylogenetic structural) EMF, while accounting effects environmental factors landscapes Benin. used forest inventory data 145 plots spanning forests, assessed implications three scenarios. quantified EMF using eight functions that are central primary productivity nutrient cycling. found was positively related solely structural diversity forests. The decreased both directly indirectly. indirect were mediated by two contrasting effects. When converted through savannas, driven shifts functional composition towards dominance species acquisitive traits. In contrast, reduction explained when parklands. aridity index soil texture influenced attributes, but not EMF. present study provides evidence biodiversity–EMF relationship is dependent LULC type evident only diversity, thereby emphasizing importance enhancing promoting Our findings also demonstrate weakened biotic homogenization resulting biodiversity‐related mechanisms, including loss resource‐use strategy.

Altitude, as a key environmental factor, shapes the spatial patterns of species diversity, phylogenetic and community structure. Studying grassland diversity structure along altitudinal gradients helps clarify how altitude-driven changes influence assembly, reveal vertical in formation. This study examines grasslands at 1300–2500 m elevation Two-River Source Forest Area, Altai Mountains, Xinjiang. Six (200 intervals) were surveyed with 90 quadrats, documenting characteristics data. The analyzes composition, phylogeny across different explores their relationships factors. results indicate that composition is dominated by from Poaceae, Rosaceae, Asteraceae families, Poa annua (annual bluegrass) being dominant within Poaceae. gradient exhibits bimodal trend, an initial increase, followed decrease, another finally decline rises. In contrast, shows unimodal pattern, characterized increase increasing elevation. Although did not exhibit significant trend transitioning divergence to clustering gradient, overall pattern communities tended toward clustering. Further analysis reveals correlations between factors such temperature, precipitation, forest cover, soil moisture. However, no found have correlation indices.
