“…The flow regime of streams and rivers has been modified by human activities at the global scale (Grill et al, 2019;Tonkin et al, 2019). As human population continues to grow, the increasing demand for water supply, flood protection and energy production has prompted the widespread adoption of engineering solutions such as the construction of dams, levees and other hydraulic infrastructures (Couto & Olden, 2018;Shumilova et al, 2018;Zarfl et al, 2015).…”

The hydrological model HYPERstreamHS was used to simulate natural streamflow series at100 bio-assessment sites across a large Alpine basin. Three flow-regime classes were identified, representing typical nivo-glacial, nivo-pluvial, and pluvial streams. Spatial stream-network models identified distinct flow-ecology relationships and relevant spatial autocorrelation across classified regimes, which can aid in the implementation of targeted water management schemes.

“…At the same time, adequate data on freshwater biodiversity are generally unavailable, especially in tropical areas despite the high levels of species diversity and endemism (Balian, Segers, Martens, & Lévéque, 2007; Dudgeon et al, 2006). In rivers, overfishing and blockage of migratory routes through damming and excessive water abstractions have placed great stress on riverine populations globally (Dudgeon et al, 2006; Grill et al, 2019). The result has been a massive reshaping of communities, with higher rates of change occurring in the tropics (Araújo et al, 2013; Collen et al, 2014).…”

Distribution patterns and diversity of riverine fishes of the Lake Victoria Basin, Kenya

et al. 2020

The Lake Victoria Basin (LVB) is a global hotspot of aquatic biodiversity, but aquatic ecosystems are under threat from multiple stressors. Most studies on fish have focused on Lake Victoria, while patterns of fish diversity, distribution, and assemblage structure in influent rivers remain poorly understood. To assess threats and conservation status of riverine fishes, we used sampling surveys and searches of published and gray literature to compile data on diversity, distribution, and abundance. In total, 72 fish species were found to inhabit Kenyan rivers and associated wetlands and lakes (excluding Lake Victoria). Low‐order streams (first to third order) in headwaters of rivers are species‐poor and dominated by small‐bodied cyprinids (Enteromius spp.) and clariids (Clarias spp.). A small number of fishes are endemic to rivers, and species turnover across river basins is low. Species dominance is high, with 10 species accounting for >90% of all individuals and weights. Two cyprinid species (Labeobarbus altianalis and Labeo victorianus) account for >65% of all individuals and weights (biomass) per unit effort. Most species occur in small numbers and low biomass is insufficient to sustain a commercial riverine fishery. A review of the literature continues to indicate a reduction in migratory runs of potamodromous fishes from Lake Victoria into influent rivers, although some species, such as L. victorianus and L. altianalis, also maintain stenotopic populations in rivers. Most of the exotic fishes introduced in Lake Victoria, such as Oreochromis nilotics, Oreochromis, Coptodon zillii, Coptodon rendalli, and Gambusia affinis, have invaded and established themselves in rivers, thereby posing a threat to riverine populations. Although this study focuses on Kenyan rivers, the distribution patterns of fishes reflect other rivers of the LVB and have broad implications on threats to riverine biodiversity in other regions undergoing development around the world.

“…Hence, the covers of conservation journals reflect the current research landscape of biodiversity conservation; so far, most research and conservation efforts have focused on terrestrial and marine ecosystems, particularly on large vertebrates (Clucas et al, 2008;Mazor et al, 2018;Tydecks et al, 2018), while only 18% of all biodiversity studies published from 1945 to 2014 are associated with freshwater ecosystems (Tydecks et al, 2018). This is despite that an urgent need for the conservation of freshwater ecosystems has been addressed over 15 years ago (Abell 2002) and a large body of research shows that threats to freshwater habitats and species are intense and increasing over the last few decades (Dudgeon et al, 2006;Vörösmarty et al, 2010;Reid et al, 2019;He et al, 2018;Grill et al, 2019). Terrestrial and marine megafauna species, which are frequently featured on covers of conservation journals (Figure 3) and popular conservation and nature magazines (Clucas et al, 2008), are the ones that receive most of research and conservation efforts (Donaldson et al, 2016;Ford et al, 2017).…”

“…Freshwater habitats including rivers, lakes, and wetlands cover less than 3% of Earth's surface but support approximately 9.5% of all described animals and one-third of vertebrates (Balian et al, 2008). Meanwhile, freshwater ecosystems are subject to tremendous and increasing pressures due to a growing demand for water, energy, and food, leading to overexploitation of freshwater and organisms (Dudgeon et al, 2006;Vörösmarty et al, 2010;Reid et al, 2019), and to the loss of important habitats such as wetlands and free-flowing rivers (Reis et al, 2017;Grill et al, 2019). Consequently, 27% of all assessed freshwater species are considered as threatened with extinction on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species (Tickner et al, 2020), while global freshwater vertebrate populations have declined by 83% from 1970 to 2014 (WWF, 2018).…”

The untapped potential of conservation journals to promote freshwater biodiversity

Freshwater ecosystems are amongst the most diverse ecosystems on the planet. They are subject to intense and increasing threats and have a higher proportion of threatened and extinct species than terrestrial or marine realms. Concurrently, freshwater ecosystems are largely underrepresented in both conservation research and actions arguably as a consequence of less popularity and promotion. To test this assumption, we used cover images as a proxy of exposure and promotion opportunities provided by conservation journals. We collected information on cover images of 18 conservation journals from 1997 to 2016 and data on citations and Altmetric scores of papers published in them. We found that freshwater ecosystems (10.4%) were featured less often than marine (15.2%) or terrestrial (74.4%) ecosystems on covers of these journals. All 15 most featured species are from terrestrial or marine ecosystems, with 14 of them being large vertebrates such as elephants, big cats, rhinos, polar bears, and marine turtles. None of the 95 species featured more than once on the covers of conservation journals spend their whole life history in fresh waters, i.e. they are at least partly associated with terrestrial or marine ecosystems. Our results indicated that cover-featured studies received more attention from academia and the general public, i.e. showed higher citations and Altmetric scores, than non-featured ones within the same issue. By featuring freshwater species and habitats on covers, therewith providing more exposure opportunities, conservation journals hold the potential to promote biodiversity conservation in fresh waters. Scientists can help that endeavour by submitting freshwater-related photos together with their manuscripts for review, therewith providing more options for editors to portray freshwater species and habitats and to ultimately raise awareness and appreciation of freshwater life.
