“…By identifying the most pressing needs to counter the freshwater biodiversity loss, our agenda is intended to maintain the global momentum recently exemplified by calls for action (Darwall et al, 2018), such as the Emergency Recovery Plan for freshwater biodiversity (Tickner et al, 2020). This includes mobilising practitioners (Twardek et al, 2021), promoting strategic activities (Arthington, 2021) and embracing the 25 essential questions to inform the protection and restoration of freshwater biodiversity (Harper et al, 2021). Our succinct and clear agenda comes at a pivotal time when governments around the world are revising major international agreements relevant to biodiversity conservation, such as the Sustainable Development Goals, or are at the brink of major conventions including the Convention on Biological Diversity and the UN Framework Convention on Climate Change.…”

Global freshwater biodiversity is declining dramatically, and meeting the challenges of this crisis requires bold goals and the mobilisation of substantial resources. While the reasons are varied, investments in both research and conservation of freshwater biodiversity lag far behind those in the terrestrial and marine realms. Inspired by a global consultation, we identify 15 pressing priority needs, grouped into five research areas, in an effort to support informed stewardship of freshwater biodiversity. The proposed agenda aims to advance freshwater biodiversity research globally as a critical step in improving coordinated actions towards its sustainable management and conservation.

“…Although lakes and other freshwater habitats cover only a small fraction of the global land surface area, they are believed to host nearly 10% of the Earth’s described animal species (Balian et al, 2008). Simultaneously, these ecosystems are currently facing a crisis in that they are experiencing a distinct decline in populations that has continued over the past several decades (Albert et al, 2021; Arthington, 2021). Various factors have been identified as contributing to this decline, including substantial terrestrial vegetation transformations caused mainly by human impacts that modify the transfer of energy and matter from catchments to aquatic ecosystems (Reid et al, 2019).…”

Responses of a shallow temperate lake ecosystem to major late-Holocene terrestrial vegetation shifts

Major terrestrial vegetation shifts (MTVSs) resulting from either human activities or natural processes can exert substantial pressure on lakes mainly through impacts on catchment biogeochemical cycles and groundwater circulation. To better understand the links between terrestrial vegetation dynamics and lake ecosystem structure and functions over long temporal scales, in this study, we reconstructed the responses of shallow Lake Spore (N Poland) to major late-Holocene vegetation shifts. We combined newly acquired data from pollen and spores, Cladocera, TOC/N, δ13C, and δ15N analyses of bulk organic matter with the already published results from sediment dating and analyses of several biotic and geochemical proxies. Statistical analysis of the abundance data for all the major terrestrial pollen taxa and reconstruction of vegetation openness derived from the REVEALS model indicated five MTVSs, each followed by a change in the lake environment. Changes in Lake Spore trophic status at MTVS1 (~2.82 kyr BP) and MTVS2 (~2.17 kyr BP) were attributed to the reorganization of the catchment’s nutrient cycling associated with a decline (MTVS1) and subsequent regeneration (MTVS2) of deciduous tree stands in the area. A distinct drop in the CaCO3 content of the lake sediments that started at MTVS4 (~0.57 kyr BP) likely occurred due to the substantial depletion of the water calcium pool following an abrupt transition from a tree-dominated to an herb-dominated landscape. Our record also suggested slight lake acidification following a spread of Pinus sylvestris at MTVS1 (~2.82 kyr BP) and MTVS3 (~1.10 kyr BP) and a lake level rise concurrent with the sharp increase in landscape openness at MTVS4 (~0.57 kyr BP).

“…Hydrological alterations, habitat degradation and loss, pollution, overexploitation, invasive species, and climate change have been detected as major threats to freshwater ecosystems [40]. Each category includes multiple stressors to biodiversity that interact, often with effects greater than (synergism), less than (antagonism), or equal to the sum of their individual effects [41,42]. Scientists have sought to identify the most significant causes of stress, understand and predict the responses of species and communities to individual and multiplestressor configurations [43,44], support administrations in developing sustainable management actions, and finding nature-based solutions according to the 2030 Agenda for Sustainable Development (https://www.un.org/sustainabledevelopment/development-agenda/ (accessed on 5 September 2021)).…”

Some pollutants can be transported through the atmosphere and travel medium–long distances to be deposited in glaciers at high altitude and latitude. The increase in the rate of glacier melting due to global warming can release these pollutants in alpine streams. This study investigated the combined effects of rising temperatures and chlorpyrifos (CPF) contamination on the swimming behaviour of alpine chironomids collected in a shrinking alpine glacier. We assessed the individual and interaction effects of rising temperatures (2–11 °C) and CPF concentrations (0–110 ng L−1) on the swimming behaviour of Diamesa zernyi (Chironomidae) larvae. Distance (mm) and speed (mm s−1) were recorded using a video-tracking system after 24–72 h of treatment. The two stressors caused different effects on distance and speed, with increasing temperature generally causing hyperactivity and CPF from hyperactivity to reduced mobility. Two interactions were detected between stressors when combined: (i) CPF superimposed the effect of temperature on both behavioural endpoints i.e., with 110 ng L−1 of CPF, at 11 °C, larvae moved less; (ii) warming (11 °C) magnified the negative effect of CPF: the smallest distance and slowest speed were recorded at the highest values of the two stressors after 72 h. Our results suggest that water contamination by CPF, even at sub-lethal concentrations, might increase the sensitivity of chironomids to warming, and vice versa, raising concerns about freshwater biodiversity conservation under climate change.
