Abstract Antarctica, Earth’s least understood and most remote continent, is threatened by human disturbances climate-related changes, underscoring the imperative for biodiversity inventories to inform conservation. Antarctic ecosystems support unique species genetic diversity, deliver essential ecosystem services contribute planetary stability. We present Antarctica’s first comprehensive classification map of ice-free lands, which host continent’s biodiversity. used latent variables in factor analyses partition continental-scale abiotic variation, then biotic variation represented spatial models, finally recognised regional-scale among biogeographic units. This produced a spatially explicit hierarchical with nine Major Environment Units (Tier 1), 33 Habitat Complexes 2) 269 Bioregional Ecosystem Types 3) mapped at 100 m resolution aligned ‘level 4’ IUCN Global Typology. inventory provides foundational data protected area designation under Treaty’s Environmental Protocol track risks ecosystems. Its tiered structure workflow accommodate scarcity facilitate updates, promoting robustness as knowledge builds.

Marine foundation species are the biotic basis for many of world's coastal ecosystems, providing structural habitat, food, and protection myriad plants animals as well ecosystem services. However, climate change poses a significant threat to ecosystems they support. We review impacts on common marine species, including corals, kelps, seagrasses, salt marsh plants, mangroves, bivalves. It is evident that have already been severely impacted by several drivers, often through interactive effects with other human stressors, such pollution, overfishing, development. Despite considerable variation in geographical, environmental, ecological contexts, direct indirect gradual warming subsequent heatwaves emerged most pervasive drivers observed impact potent across all but from sea level rise, ocean acidification, increased storminess expected increase. Documented include changes genetic structures, physiology, abundance, distribution themselves their interactions flow-on associated communities, biodiversity, functioning. discuss strategies support into Anthropocene, order increase resilience ensure persistence services provide.

Abstract The brief history of monitoring nutrient levels in Chinese lake waters limits our understanding the causes and long-term trends their eutrophication constrains effective management. We therefore synthesize data from lakes China to reveal historical changes project future 2100 using models. Here we show that average concentrations nitrogen phosphorus sediments have increased by 267% 202%, respectively since 1850. In model projections, 2030–2100, studied may decrease, for example, 87% southern districts 19% northern districts. However, will continue increase an 25% Eastern Plain, Yunnan–Guizhou Plateau, Xinjiang. Based on this differentiation, suggest management should be carried out at district level help develop rational sustainable environmental strategies.

Coral reefs underpin the environmental, social, and economic fabrics of much world's tropical coast. Yet, fine-scale distribution composition coral have never been reported consistently across planet. Here, we present new area estimates enabled by global geomorphic zone benthic substrate maps at 5 m pixel resolution. We revise reef to 348,361 km2 shallow 80,213 (46,237–106,319 km2, 95% confidence interval) habitat.

ABSTRACT Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater land. However, we lack a unified methodology to report this sampling effort comprehensive overview of PAM coverage gauge its potential as global research tool. To address gap, created the Worldwide Soundscapes project, collaborative network growing database comprising metadata from 416 datasets across all realms (terrestrial, marine, freshwater subterranean). Location Worldwide, 12,343 sites, ecosystem types. Time Period 1991 present. Major Taxa Studied All soniferous taxa. Methods We synthesise spatial, temporal ecological scales using describing locations, deployment schedules, focal taxa audio recording parameters. explore trends biological, anthropogenic geophysical sounds based 168 selected recordings 12 realms. Results Terrestrial is spatially denser (46 sites per million square kilometre—Mkm 2 ) than aquatic (0.3 1.8 sites/Mkm oceans fresh water) with only two subterranean datasets. Although diel lunar cycles are well sampled realms, marine (55%) comprehensively sample seasons. Across exploring acoustic trends, biological showed contrasting patterns ecosystems, declined distance Equator, were negatively correlated sounds. Main Conclusions inform macroecological studies conservation phenology syntheses, but representation be improved by expanding terrestrial taxonomic scope, high seas spatio‐temporal replication habitats. Overall, holds promise support cross‐realm efforts.

Abstract Groundwater is a vital ecosystem of the global water cycle, hosting unique biodiversity and providing essential services to societies. Despite being largest unfrozen freshwater resource, in period depletion by extraction pollution, groundwater environments have been repeatedly overlooked conservation agendas. Disregarding importance as an ignores its critical role preserving surface biomes. To foster timely groundwater, we propose elevating concept keystone species into realm ecosystems, claiming that influences integrity many dependent ecosystems. Our analysis shows over half land areas (52.6%) has medium‐to‐high interaction with reaching up 74.9% when deserts high mountains are excluded. We postulate intrinsic transboundary features for shifting perspectives towards more holistic approaches aquatic ecology beyond. Furthermore, eight key themes develop science‐policy integrated agenda. Given ecosystems above below ground intersect at levels, considering component planetary health pivotal reduce loss buffer against climate change.

Here, we investigated trends, drought drivers three water-use indices from 1995–2018 Europe with remote sensing data that considered long-term environmental effects. We show inherent decreased −4.2% Central Europe, exhibiting threatened functioning. In European grasslands it increased +24.2%, regulated transpiration assimilation. Further, highlight modulation hydro-climate importance adaptive canopy conductance on function. Our results imply decoupling assimilation efficient management strategies could make difference between well-coping ecosystems ongoing change, provide important insights for land surface model development.
