Abstract Headwater springs and streams often occur in relatively remote areas, reducing their exposure to human influences thus increasing collective capacity support high biodiversity. Their aquatic macroinvertebrate communities can include species of conservation interest, some which are specialists associated with groundwater inputs, low water temperature or temporary flow. However, the inaccessibility spring stream networks has left poorly characterized, limiting our implement effective strategies. We characterized biodiversity value a network 51 inaccessible unimpacted headwater sites spanning multiple catchments single landscape type: chalk downland south England. At each site, we kick sampled recorded environmental variables, including flow permanence.

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.

Subterranean ecosystems (e.g., caves, groundwaters, fissure systems) are often overlooked in global climate change and conservation agendas. This contrasts with their widespread distribution, rich biodiversity, importance to humans as providers of multiple ecosystem services. Worryingly, evidence is accumulating regarding diverse biological alterations subterranean under exposure. Yet, we lack quantification the magnitude these impacts across scales components. Here, assembled a dataset covering 347 measurements impact at organismal physiology, behavior, population/community, habitat levels. Through meta-analysis, showed that effects act gene community levels varying strength direction depending on habitat, taxa, degree specialization. By building nuanced understanding multilevel ecosystems, our analysis underscores vulnerability different components, providing supported rationale for incorporation into agendas through targeted measures.

Subterranean ecosystems (comprising terrestrial, semi-aquatic, and aquatic components) are increasingly threatened by human activities; however, the current network of surface-protected areas is inadequate to safeguard subterranean biodiversity. Establishing protected for challenging. First, there technical obstacles in mapping three-dimensional with uncertain boundaries. Second, rarity endemism organisms, combined a scarcity taxonomists, delays accumulation essential biodiversity knowledge. Third, establishing agreements preserve requires collaboration among multiple actors often competing interests. This perspective addresses challenges preserving through areas.

Abstract Groundwater is an important global resource, providing water for irrigation, industry, geothermal uses and potable water. Moreover, groundwater contains the world's largest terrestrial freshwater biome with ecosystems, inhabited mainly by invertebrates (stygofauna) microbes, undertaking services including purification, as well nutrient carbon cycling. Despite investigations on spatial temporal variations of fauna influence environmental parameters these organisms, in parts world, even most basic knowledge ecosystems still lacking. The aims this study are to provide overview research, historical evolution research topics development sampling methods secondly identify distribution resulting data gaps. To achieve this, extensive review accessible was conducted analysing 859 studies. It evident that over time, there has been exponential increase number studies together changing paradigms focus, particularly have developed from using simple nets, substrate samples hand‐pumps beginning recent molecular analyses (e.g. eDNA).
