Freshwater ecosystems are among the most diverse and dynamic on Earth. At same time, they threatened but remain underrepresented in biodiversity research conservation efforts. The rate of decline vertebrate populations is much higher freshwaters than terrestrial or marine realms. megafauna (i.e., freshwater animals that can reach a body mass ≥30 kg) intrinsically prone to extinction due their large size, complex habitat requirements slow life-history strategies such as long life span late...
Dam construction comes with severe social, economic and ecological impacts. From an point of view, habitat types are altered biodiversity is lost. Thus, to identify areas that deserve major attention for conservation, existing planned locations (hydropower) dams were overlapped, at global extent, the contemporary distribution freshwater megafauna species consideration their respective threat status. Hydropower development will disproportionately impact high richness in South America, East...
Global freshwater biodiversity is declining dramatically, and meeting the challenges of this crisis requires bold goals mobilisation substantial resources. While reasons are varied, investments in both research conservation lag far behind those terrestrial marine realms. Inspired by a global consultation, we identify 15 pressing priority needs, grouped into five areas, an effort to support informed stewardship biodiversity. The proposed agenda aims advance globally as critical step improving...
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,...
Abstract Stream metacommunities are structured by a combination of local (environmental filtering) and regional (dispersal) processes. The unique characters high mountain streams could potentially determine metacommunity structuring, which is currently poorly understood. Aiming at understanding how these influenced we explored the relative importance environmental conditions various dispersal processes, including through geographical (overland), topographical (across barriers) network (along...
Abstract Aim Freshwater megafauna remain underrepresented in research and conservation, despite a disproportionately high risk of extinction due to multiple human threats. Therefore, our aims are threefold; (i) identify global patterns freshwater richness endemism, (ii) assess the conservation status (iii) demonstrate spatial temporal pressure throughout their distribution ranges. Location Global. Methods We identified 207 extant species, based on 30 kg weight threshold, mapped distributions...
Abstract A recent global meta‐analysis reported a decrease in terrestrial but increase freshwater insect abundance and biomass (van Klink et al., Science 368, p. 417). The authors suggested that water quality has been improving, thereby challenging reports documenting drastic declines biodiversity. We raise two major concerns with the suggest these account for discrepancy elsewhere. First, total alone are poor indicators of status assemblages, observed differences may well have driven by...
Concern for megafauna is increasing among scientists and non-scientists. Many studies have emphasized that play prominent ecological roles provide important ecosystem services to humanity. But, what precisely are 'megafauna'? Here, we critically assess the concept of propose a goal-oriented framework megafaunal research. First, review definitions analyse associated terminology in scientific literature. Second, conduct survey ecologists palaeontologists species traits used identify define...
Abstract Aim Understanding the variation in biodiversity and its underlying drivers mechanisms is a core task biogeography ecology. We examined (a) relative contributions of species replacement (i.e., turnover) richness difference nestedness) to taxonomically trait‐based β ‐diversity stream benthic algae; (b) whether these two facets are correlated with each other; (c) local environmental, geo‐climatic spatial factors their components. Location Hun‐Tai River Basin, northeastern China. Taxon...
Freshwater megafauna, such as sturgeons, giant catfishes, river dolphins, hippopotami, crocodylians, large turtles, and salamanders, have experienced severe population declines range contractions worldwide. Although there is an increasing number of studies investigating the causes megafauna losses in fresh waters, little attention has been paid to synthesising impacts on abiotic environment other organisms freshwater ecosystems, hence consequences losing these species. This limited...
The metacommunity concept has been widely used to explain the biodiversity patterns at various scales. It considers influences of both local (e.g., environmental filtering and biotic interactions) regional processes dispersal limitation) in shaping community structures. Compared spatial processes, influence interactions on streams received limited attention. We investigated relative importance three ecological namely (including geo-climatic factors), (represented by macroinvertebrates...
Environmental regimes (or environmental legacy or historical legacy) are the dynamics of characteristics over a given (either long short) time period, such as frequency mean extreme events and rate change, which might be absent by using only contemporary variables. We present SER, an R package for estimating different Using data included in package, several examples shown. SER is suitable any type biotic variables, including nutrient concentration, light, dissolved oxygen. In addition,...
Human activities have significantly impacted natural habitats and wildlife worldwide, particularly emphasizing repercussions for freshwater associated species. These negative impacts on fish are well known, but mammal species that regularly use dependend systems, there is an incomplete understanding. Here, we assessed the status of semi-aquatic inhabiting dependent ecosystems (hereafter referred to as mammals) evaluated impact human richness both globally by biogeographical regions. We used...
Abstract Recent years have witnessed a surge in research on the effects of multiple stressors freshwater ecosystems. While studies increased, synthesis their findings into broader understanding ecosystem‐level remains an ongoing endeavour. Leaf litter decomposition, frequently investigated and pivotal ecosystem function freshwaters, is sensitive to changes abiotic conditions biotic communities, therefore susceptible multiple‐stressor effects. Here, we synthesize from 27 manipulative...
Multiple stressors, such as pollution, climate change, invasive species and fragmentation, threaten global ecosystems, requiring holistic management actions. Freshwater ecosystems are disproportionately biodiverse particularly impacted by fragmentation biological invasions. Artificial barriers, dams weirs, long-standing features of landscapes, with a divergence views on their benefits disbenefits. Recognition the negative impacts barriers river continuum native biota, for migratory aquatic...
Abstract Sturgeons and paddlefishes (Acipenseriformes) are among the most threatened species worldwide. In Yangtze River, all three Acipenseriformes either extinct or have failed natural reproduction recruitment due to overfishing habitat destruction. Although many conservation measures been implemented, no of sturgeon ( Acipenser dabryanus ) has observed in wild since 2000. New restoration actions urgently needed save sturgeons from extinction River. We established large‐scale ecohydraulic...
Abstract Recent decades have witnessed a sharp biodiversity decline in freshwaters due to multiple stressors. The presence of stressors is expected affect community structure and interactions freshwater ecosystems, with subsequent functional consequences. We synthesized the state experimental, manipulative multiple‐stressor studies that focused on multispecies assemblages freshwaters. Compared rivers lakes, wetland groundwater ecosystems received much less attention identified research. Most...
Understanding processes and mechanisms driving patterns of species distribution diversity is a vital theme in community ecology conservation biology. There has been continuous increase studies focusing on freshwater ecosystems during the last few decades. However, comparative distributions, underlying across trophic levels remain limited. The unique characteristics study area (i.e. Hun-Tai River Northeast China) generates wide range environmental conditions to advance our understanding what...
Abstract Motivation Aquatic insects comprise 64% of freshwater animal diversity and are widely used as bioindicators to assess water quality impairment ecosystem health, well test ecological hypotheses. Despite their importance, a comprehensive, global database aquatic insect occurrences for mapping biodiversity in macroecological studies applied research is missing. We aim fill this gap present the Global EPTO Database , which includes worldwide geo‐referenced occurrence records four major...
Abstract Freshwater megafish species, such as sturgeons, salmonids, carps, and catfishes, have a maximum reported weight ≥30 kg. Due to their charisma economic value, they been widely introduced outside of native ranges. Here, we provide comprehensive overview the introduction freshwater an assessment environmental impacts. Of 134 extant 46% new environments, these, 69% established self‐sustaining alien populations. These introductions affect 59% world's main basins, with USA western Europe...
