A global agenda for advancing freshwater biodiversity research

Ecology Letters, Journal Year: 2021, Volume and Issue: 25(2), P. 255 - 263

Published: Dec. 1, 2021

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 coordinated actions towards its sustainable management conservation.

People need freshwater biodiversity

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; education science; recreation), regulating (catchment integrity; climate regulation; water purification nutrient cycling). If is protected, conserved, restored in an integrated manner, as well more broadly appreciated by humanity, it will contribute human well‐being our sustainable future via this wide range associated nature‐based solutions future.

Biological invasions and invasive species in freshwaters: perception of the general public

Human Dimensions of Wildlife, Journal Year: 2023, Volume and Issue: 29(1), P. 48 - 63

For management strategies aimed at biological invasions, a detailed survey of the general public's knowledge is crucial. this purpose, our present study to (i) investigate level comprehension regarding (ii) assess ability responders discriminate between invasive and native species, (iii) evaluate conservation support. Increased awareness invasions on part respondents positively influences willingness protect fish crayfish species not their counterparts. Higher identification scores by participants significantly decreased support species. Female were more willing including ones. Respondents could better extent than crayfish. Without public citizen-aimed education, we will be unable conduct sustainable prevent further species' introductions translocations.

ABSTRACT Freshwater biodiversity conservation has received substantial attention in the scientific literature and is finally being recognized policy frameworks such as Global Biodiversity Framework its associated targets for 2030. This important progress. Nonetheless, freshwater species continue to be confronted with high levels of imperilment widespread ecosystem degradation. An Emergency Recovery Plan (ERP) proposed 2020 comprises six measures intended “bend curve” loss, if they are widely adopted adequately supported. We review evidence suggesting that combined intensity persistent emerging threats become so serious current projected efforts preserve, protect restore inland‐water ecosystems may insufficient avert losses coming decades. In particular, climate change, complex harmful impacts, will frustrate attempts prevent from already affected by multiple threats. Interactions among these limit recovery populations exacerbate declines resulting local or even global extinctions, especially low‐viability degraded fragmented ecosystems. addition impediments represented we identify several other areas where absolute scarcity fresh water, inadequate information predictive capacity, a failure mitigate anthropogenic stressors, liable set limits on biodiversity.

The alarming state of freshwater biodiversity in Canada

Canadian Journal of Fisheries and Aquatic Sciences, Journal Year: 2021, Volume and Issue: 79(2), P. 352 - 365

Little is known about the current state of freshwater biodiversity in Canada, one countries with greatest amount surface waters world. To address this knowledge gap, we compiled a list all available assessments conservation status for species (over 3000 taxa) and further evaluated overall six distinct taxonomic groups, focusing on organisms reliant fresh (i.e., aquatic plants, invertebrates (with focus mussels), fishes, herpetofauna (reptiles amphibians), birds, mammals). Overall, 11.7% plants animals assessed were found to be “at risk” listed as “Threatened”, “Endangered”, or “Extirpated”) 17.9% identified “Special Concern”. We that 37.9% lacked sufficient data enable their assessed. Data gaps Canada’s assessment its most prevalent (excluding mussels). Given alarming conclude by providing recommendations evaluating temporal trends informing actions.
