Environmental DNA: What's behind the term? Clarifying the terminology and recommendations for its future use in biomonitoring

Molecular Ecology, Journal Year: 2020, Volume and Issue: 29(22), P. 4258 - 4264

Published: Sept. 23, 2020

The last decade brought a spectacular development of so-called environmental (e)DNA studies. In general, "environmental DNA" is defined as DNA isolated from samples, in contrast to genomic that extracted directly specimens. However, the variety different sources eDNA and range taxonomic groups are targeted by studies large, which has led some discussion about breadth concept. particular, there recent trend restrict use term "eDNA" macro-organisms, not physically present samples. this paper, we argue such distinction may be ideal, because signal can come organisms across whole tree life. Consequently, advocate should used its generic sense, originally defined, encompassing all including microbial, meiofaunal macrobial taxa. We first suggest specifying origin sample, water eDNA, sediment or soil eDNA. A second specification would then define group through polymerase chain reaction amplification, fish invertebrate bacterial This terminology does also require assumptions specific state sampled (intracellular extracellular). hope will help better scope studies, especially for managers, who them reference routine biomonitoring bioassessment.

Diversification of Neotropical Freshwater Fishes

Annual Review of Ecology Evolution and Systematics, Journal Year: 2020, Volume and Issue: 51(1), P. 27 - 53

Published: July 31, 2020

Neotropical freshwater fishes (NFFs) constitute the most diverse continental vertebrate fauna on Earth, with more than 6,200 named species compressed into an aquatic footprint <0.5% of total regional land-surface area and representing greatest phenotypic disparity functional diversity any ichthyofauna. Data from fossil record time-calibrated molecular phylogenies indicate that higher taxa (e.g., genera, families) diversified relatively continuously through Cenozoic, across broad geographic ranges South American platform. Biodiversity data for NFF clades support a model radiation rather adaptive radiation, in which speciation occurs mainly allopatry, adaptation are largely decoupled. These radiations occurred under perennial influence river capture sea-level oscillations, episodically fragmented merged portions adjacent networks. The future Anthropocene is uncertain, facing numerous threats at local, regional, scales.

People need freshwater biodiversity

Wiley Interdisciplinary Reviews Water, Journal Year: 2023, Volume and Issue: 10(3)

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.

Rising water temperature in rivers: Ecological impacts and future resilience

Wiley Interdisciplinary Reviews Water, Journal Year: 2024, Volume and Issue: 11(4)

Published: March 5, 2024

Abstract Rising water temperatures in rivers due to climate change are already having observable impacts on river ecosystems. Warming has both direct and indirect aquatic life, further aggravates pervasive issues such as eutrophication, pollution, the spread of disease. Animals can survive higher through physiological and/or genetic acclimation, behavioral phenological change, range shifts more suitable locations. As such, those animals that adapted cool‐water regions typically found high altitudes latitudes where there fewer dispersal opportunities most at risk future extinction. However, sub‐lethal animal physiology phenology, body‐size, trophic interactions could have significant population‐level effects elsewhere. Rivers vulnerable warming because historic management left them exposed solar radiation removal riparian shade, hydrologically disconnected longitudinally, laterally, vertically. The resilience riverine ecosystems is also limited by anthropogenic simplification habitats, with implications for resource use resident organisms.

Biological invasions are a population‐level rather than a species‐level phenomenon

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(5)

Biological invasions pose a rapidly expanding threat to the persistence, functioning and service provisioning of ecosystems globally, socio-economic interests. The stages successful are driven by same mechanism that underlies adaptive changes across species in general-via natural selection on intraspecific variation traits influence survival reproductive performance (i.e., fitness). Surprisingly, however, rapid progress field invasion science has resulted predominance species-level approaches (such as deny lists), often irrespective theory, local adaptation other population-level processes govern invasions. To address these issues, we analyse non-native dynamics at population level employing database European freshwater macroinvertebrate time series, investigate spreading speed, abundance impact assessments among populations. Our findings reveal substantial variability speed trends within between biogeographic regions, indicating levels invasiveness differ markedly. Discrepancies inconsistencies risk screenings real data were also identified, highlighting inherent challenges accurately assessing effects through assessments. In recognition importance assessments, urge shift invasive management frameworks, which should account for different populations their environmental context. Adopting an adaptive, region-specific population-focused approach is imperative, considering diverse ecological contexts varying degrees susceptibility. Such could improve refine while promoting mechanistic understandings risks impacts, thereby enabling development more effective conservation strategies.

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, there is evidence 14–17 that such insufficient represent the needs freshwater species achieve biodiversity goals 18,19 Here we present results a multi-taxon fauna assessment The IUCN Red List Threatened Species covering 23,496 decapod crustaceans, fishes odonates, finding one-quarter threatened with extinction. Prevalent threats include pollution, dams water extraction, agriculture invasive species, overharvesting also driving extinctions. We examined degree surrogacy both (water nitrogen) species. good surrogates when prioritizing sites maximize rarity-weighted richness, poorer based on most range-restricted they much better than factors, which perform worse random. Thus, although priority regions identified tetrapod broadly reflective those faunas, given differences key habitats, meeting cannot be assumed sufficient conserve at local scales.

Despite increasing evidence of off-site ecological impacts pesticides and policy efforts worldwide, pesticide use is still far from being ecologically sustainable. Fungicides are among the most sold classes crucial to ensure global food supply security. This study aimed identify potential gaps knowledge mismatches between research usage data fungicides by: (i) systematizing current trends in sales fungicides, focusing on European context particular (where they proportionally important); (ii) reviewing scientific literature synthetic non-target freshwater organisms. Sales revealed important regional asymmetries relative importance preferred active ingredients. The review effects disclosed a mismatch studied substances, as well bias towards single species assays with standard test To proper evaluation, risk scenarios should focus scale, agendas must highlight sensitive aquatic ecorreceptors improve crosstalk analytical data.
