Despite their limited spatial extent, freshwater ecosystems host remarkable biodiversity, including one-third of all vertebrate species. This biodiversity is declining dramatically: Globally, wetlands are vanishing three times faster than forests, and populations have fallen more twice as steeply terrestrial or marine populations. Threats to well documented but coordinated action reverse the decline lacking. We present an Emergency Recovery Plan bend curve loss. Priority actions include...

Abstract Global pressures on freshwater ecosystems are high and rising. Viewed primarily as a resource for humans, current practices of water use have led to catastrophic declines in species the degradation ecosystems, including their genetic functional diversity. Approximately three‐quarters world's inland wetlands been lost, one‐third 28 000 assessed International Union Conservation Nature (IUCN) Red List threatened with extinction, vertebrate populations undergoing that more rapid than...

Abstract Freshwater biodiversity, from fish to frogs and microbes macrophytes, provides a vast array of services people. Mounting concerns focus on the accelerating pace biodiversity loss declining ecological function within freshwater ecosystems that continue threaten these natural benefits. Here, we catalog nine fundamental ecosystem biotic components indigenous provide people, organized into three categories: material (food; health genetic resources; goods), non‐material (culture;...

Abstract Freshwater ecosystems are highly biodiverse 1 and important for livelihoods economic development 2 , but under substantial stress 3 . To date, comprehensive global assessments of extinction risk have not included any speciose groups primarily living in freshwaters. Consequently, data from predominantly terrestrial tetrapods 4,5 used to guide environmental policy 6 conservation prioritization 7 whereas recent proposals target setting freshwaters use abiotic factors 8–13 However,...

Abstract Protected areas, although often terrestrially focused and less frequently designed to protect freshwater resources, can be extremely important for conserving biodiversity supporting human water security necessary people survive thrive. This study measured the quantity of that is being provided by protected areas downstream, how threatened are in terms their provision. Building on a Freshwater Provision Index, numbers who live downstream from these around world were then assessed....

Freshwater biodiversity is highly threatened and decreasing more rapidly than its terrestrial or marine counterparts; however, freshwaters receive less attention conservation investment other ecosystems do. The diverse group of freshwater megafauna, including iconic species such as sturgeons, river dolphins, turtles, could, if promoted, provide a valuable tool to raise awareness funding for conservation. We found that megafauna inhabit every continent except Antarctica, with South America,...

Target 11 describes what an improved conservation network would look like marine, terrestrial inland water areas, including freshwater ecosystems. To date, there is no comprehensive assessment needs achieved meet biodiversity. Reports...

Abstract Freshwater biodiversity is declining at an unprecedented rate. conservationists and environmental managers have enough evidence to demonstrate that action must not be delayed but insufficient identify those actions will most effective in reversing the current trend. Here, focus on identifying essential research topics that, if addressed, contribute directly restoring freshwater through supporting ‘bending curve’ (i.e. leading recovery of biodiversity, simply deceleration downward...

Some conservation prioritization methods are based on the assumption that needs overwhelm current resources and not all species can be conserved; therefore, a triage scheme (i.e., when system is overwhelmed, should divided into three groups likelihood of survival, efforts focused those in group with best survival prospects reduced or denied to no needing special for their conservation) necessary guide resource allocation. We argue this decision-making strategy appropriate because as limited...

Freshwater biodiversity is under great threat across the globe as evidenced by more severe declines relative to other types of ecosystems. Some main stressors responsible for these concerning trends habitat fragmentation, degradation, and loss stemming from anthropogenic activities, including energy production, urbanization, agriculture, resource extraction. Habitat protection restoration both play an integral role in efforts save freshwater associated ecosystem services further decline. In...

Rivers, wetlands, lakes, and other freshwater ecosystems collectively cover only 1% of the Earth's surface. Yet, these support a disproportionately large vast array biodiversity. Currently, face many threats, including pollution, habitat alteration, fragmentation, invasive species, overexploitation, overabstraction, climate change, emerging stressors. According to World Wide Fund for Nature's Living Planet Index, biodiversity are considered among most threatened on planet, with average...
