The 196 parties to the Convention on Biological Diversity (CBD) will soon agree a post-2020 global framework for conserving three elements of biodiversity (genetic, species, and ecosystem diversity) while ensuring sustainable development benefit sharing. As most significant conservation policy mechanism, new CBD has far-reaching consequences- it guide actions reporting each member country until 2050. In previous strategies, as well other major mechanisms, targets indicators genetic diversity...
International agreements such as the Convention on Biological Diversity (CBD) have committed to conserve, and sustainably equitably use, biodiversity. The CBD is a vital instrument for global conservation because it guides 195 countries European Union in setting priorities allocating resources, requires regular reporting progress. However, similar policy often neglected genetic diversity. This critical gap diversity underlies adaptation environmental change ecosystem resilience. Here we aim...
Genetic diversity among and within populations of all species is necessary for people nature to survive thrive in a changing world. Over the past three years, commitments conserving genetic have become more ambitious specific under Convention on Biological Diversity's (CBD) draft post-2020 global biodiversity framework (GBF). This Perspective article comments how goals targets GBF evolved, improvements that are still needed, lessons learned from this process, connections between actions...
The International Union for Conservation of Nature (IUCN) Red List is an important and widely used tool conservation assessment. IUCN uses information about a species' range, population size, habitat quality fragmentation levels, trends in abundance to assess extinction risk. Genetic diversity not considered, although it affects Declining populations are more strongly affected by genetic drift higher rates inbreeding, which can reduce the efficiency selection, lead fitness declines, hinder...
Abstract Genetic monitoring of populations currently attracts interest in the context Convention on Biological Diversity but needs long-term planning and investments. However, genetic diversity has been largely neglected biodiversity monitoring, when addressed, it is treated separately, detached from other conservation issues, such as habitat alteration due to climate change. We report an accounting efforts monitor population Europe (genetic effort, GME), evaluation which can help guide...
Abstract Under the recently adopted Kunming‐Montreal Global Biodiversity Framework, 196 Parties committed to reporting status of genetic diversity for all species. To facilitate reporting, three indicators were developed, two which focus on processes contributing conservation: maintaining genetically distinct populations and ensuring are large enough maintain diversity. The major advantage these is that they can be estimated with or without DNA‐based data. However, demonstrating their...
Abstract Measuring genetic diversity of wild species using DNA-based data remains resource intensive and time consuming for nearly all species. However, assessments are needed global conservation commitments, including the Convention on Biological Diversity, governments managers to evaluate progress, as well prioritizing populations preserve recover (e.g., via rescue). Recently, indicators were developed tracking reporting status trends hundreds The quantify two simple proxies...
Abstract Recent scientific evidence shows that genetic diversity must be maintained, managed, and monitored to protect biodiversity nature's contributions people. Three indicators, two of which do not require DNA‐based assessment, have been proposed for reporting the Convention on Biological Diversity other conservation policy initiatives. These indicators allow an approximation status trends inform policy, using existing demographic geographic information. Application these has initiated...
Intraspecific diversity informs the demographic and evolutionary histories of populations, should be a main conservation target. Although approaches exist for identifying relevant biological units, attempts to identify priority areas intraspecific are scarce, especially within multi-specific framework. We used neutral molecular data on six European freshwater fish species (Squalius cephalus, Phoxinus phoxinus, Barbatula barbatula, Gobio occitaniae, Leuciscus burdigalensis Parachondrostoma...
Abstract Landscape features notoriously affect spatial patterns of biodiversity. For instance, in dendritic ecological networks (such as river basins), connectivity has been proposed to create unique Here, we compared genetic datasets simulated under a lattice‐like, and circular landscape test the influence on neutral diversity. The had level similar that landscape, so isolate dendricity We found diversity differentiation varied strikingly among three landscapes. generated higher total...
Abstract Population structure can significantly affect genetic‐based demographic inferences, generating spurious bottleneck‐like signals. Previous studies have typically assumed island or stepping‐stone models, which are characterized by symmetric gene flow. However, many organisms asymmetric Here, we combined simulated and empirical data to test whether flow affects the inference of past changes. Through analysis genetic with three methods (i.e. bottleneck , M ‐ratio msvar ), demonstrated...
Abstract Rivers are fascinating ecosystems in which the eco‐evolutionary dynamics of organisms constrained by particular features, and biologists have developed a wealth knowledge about freshwater biodiversity patterns. Over last 10 years, our group used holistic approach to contribute this focusing on causes consequences intraspecific diversity rivers. We conducted empirical works temperate permanent rivers from southern France, we broadened scope findings using experiments, meta‐analyses,...
Abstract Millette et al . (Ecology Letters, 2020, 23:55–67) reported no consistent worldwide anthropogenic effects on animal genetic diversity using repurposed mitochondrial DNA sequences. We reexamine data from this study, describe marker and scale limitations which might lead to misinterpretations with conservation implications, provide advice improve future macrogenetic studies.
Abstract Effective population size ( N e ) is a pivotal evolutionary parameter with crucial implications in conservation practice and policy. Genetic methods to estimate have been preferred over demographic because they rely on genetic data rather than time‐consuming ecological monitoring. Methods based linkage disequilibrium (LD), particular, become popular as require single sampling provide estimates that refer recent generations. A software program the LD method, GONE, looks particularly...
Summary Molecular genetic techniques have been used in freshwater biology for more than 30 years. Early work focussed on studies of population structure, systematics and taxonomy. More recently, the range has broadened to include ecology adaptation. Advances analytical methods technology (e.g. next‐generation sequencing) decreasing costs data production ensure that field will continue develop broaden scope. At least three factors make application molecular exciting. First, highly variable...
Summary Species‐genetic diversity correlations (SGDCs) have been investigated over a large spectra of organisms, which has greatly improved our understanding parallel processes potentially driving both species and genetic diversity. However, there are still few studies comparing SGDCs (and underlying processes) for multiple sampled single landscape. Here, focusing on freshwater fish across river basin (the Garonne‐Dordogne basin, France), we combined multi‐species approach causal analyses to...
Summary Teleost fishes interact with diverse microbial communities, playing crucial functions for host fitness. While gut microbiome has been extensively studied, skin overlooked. Specifically, there is no assessment of the relative impact and environmental factors on variability as well neutral processes shaping fish microbiome. Here, we assessed a Siluriforme, European catfish ( Silurus glanis ) sampled in four sites located Southwestern France. We roles individual features (body size...
In agreement with us, Frankham (2021) highlights the urgent necessity for CBD to include an indicator that tracks maintenance of genetic diversity within populations all species-wild and domestic.Draft Headline indicators (which Parties will need report) do not wild species (CBD/ SBSTTA/24/3Add.1).The genetically effective population size (N e ) is a metric quantifies rate change population.We welcome Frankham's comments on relevance this important parameter, appropriate threshold > 500 or N...
Abstract Genetic diversity is essential for maintaining healthy populations and ecosystems. Several approaches have recently been developed to evaluate population genetic trends without necessarily collecting new data. Such “genetic indicators” enable rapid, large-scale evaluation across dozens thousands of species. Empirical studies, when available, provide detailed information that important management, such as estimates gene flow, inbreeding, erosion adaptation. In this article, we argue...
ABSTRACT Global conservation targets aim to expand protected areas and maintain species’ genetic diversity. Whether capture diversity is unclear. We examined this question using a global sample of nuclear population‐level microsatellite data comprising genotypes from 2513 sites, 134,183 individuals, 176 mammal marine fish species. The differentiation samples inside outside were similar, with some evidence for higher in small‐bodied mammals. Mammal populations, particularly large species,...
