Abstract The mutation process at microsatellite loci typically occurs high rates and with stepwise changes in allele sizes, features that may introduce bias when using classical measures of population differentiation based on identity (e.g., FST, Nei’s Ds genetic distance). Allele size-based differentiation, assuming a [e.g., Slatkin’s RST, Goldstein et al.’s (δμ)2], better reflect loci, but they suffer sampling variance. relative efficiency size- vs. identity-based statistics depends the...
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...
Abstract Global conservation policy and action have largely neglected protecting monitoring genetic diversity—one of the three main pillars biodiversity. Genetic diversity (diversity within species) underlies species’ adaptation survival, ecosystem resilience, societal innovation. The low priority given to has been due knowledge gaps in key areas, including importance trends change; perceived high expense availability scattered nature data; complicated concepts information that are...
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...
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 We used chloroplast polymerase chain reaction‐restriction‐fragment length polymorphism (PCR‐RFLP) and microsatellites to assess the structure of genetic variation postglacial history across entire natural range common ash ( Fraxinus excelsior L.), a broad‐leaved wind‐pollinated wind‐dispersed European forest tree. A low level was observed, with only 12 haplotypes at four polymorphic in 201 populations, two PCR‐RFLP subset 62 populations. The clear geographical pattern displayed by...
DNA polymorphism at 22 loci was studied in an average of 47 Norway spruce [Picea abies (L.) Karst.] haplotypes sampled seven populations representative the natural range. The overall nucleotide variation limited, being lower than that observed most plant species so far studied. Linkage disequilibrium also restricted and did not extend beyond a few hundred base pairs. All populations, with exception Romanian population, could be divided into two main domains, Baltico-Nordic Alpine one. Mean...
To determine extant patterns of population genetic structure in common ash and gain insight into postglacial recolonization processes, we applied multilocus‐based Bayesian approaches to data from 36 European populations genotyped at five nuclear microsatellite loci. We identified two contrasting terms structure: (1) a large area the British Isles Lithuania throughout central Europe constituted effectively single deme, whereas (2) strong differentiation occurred over short distances Sweden...
The Rand Flora is a well-known floristic pattern in which unrelated plant lineages show similar disjunct distributions the continental margins of Africa and adjacent islands-Macaronesia-northwest Africa, Horn Africa-Southern Arabia, Eastern Southern Africa. These are now separated by environmental barriers such as arid regions Sahara Kalahari Deserts or tropical lowlands Central Alternative explanations for range from vicariance climate-driven extinction widespread pan-African flora to...
Forest trees are an unparalleled group of organisms in their combined ecological, economic and societal importance. With widespread distributions, predominantly random mating systems large population sizes, most tree species harbour extensive genetic variation both within among populations. At the same time, demographic processes associated with Pleistocene climate oscillations land‐use change have affected contemporary range‐wide diversity may impinge on potential for future adaptation....
This review highlights some of the discoveries and applications made possible by "omics" technologies over last 10 years provides perspectives for pioneering research to increase our understanding tree biology. A decade after first forest genome sequence was released into public domain, rapidly evolving genomics bioinformatics toolbox has advanced structure, functioning, evolution genomes. that have trees past years. In this review, we start current intricacies gene regulation reproduction,...
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...
The conservation of biodiversity from the genetic to community levels is fundamental for continual provision ecosystem services (ES), benefits that ecosystems provide people. Genetic and genomic diversity enhance resilience populations communities underpin functions services. We show genomics applications are mostly limited flagship species their ES management underachieved. propose a framework on how can guide sustainable bridge this genomics-ES 'application gap'. review knowledge in single...
The delay between environmental changes and the corresponding genetic responses within populations is a common but surprisingly overlooked phenomenon in ecology, evolutionary conservation genetics. This time lag problem can lead to erroneous assessments when solely relying on data. We identify population size, life-history traits, reproductive strategies severity of decline as main determinants lags, evaluate potential confounding factors affecting parameters during propose methodological...
Abstract Spatial genetic structure was analysed with five highly polymorphic microsatellite loci in a Romanian population of common ash ( Fraxinus excelsior L.), wind‐pollinated and wind‐dispersed tree species occurring mixed deciduous forests over almost all Europe. Contributions seed pollen dispersal to total gene flow were investigated by analysing the pattern decrease kinship coefficients among pairs individuals geographical distance comparing it simulation results. Plots against...
Abstract We investigated range‐wide phylogeographic variation in three European ash species ( Fraxinus sp., Oleaceae). Chloroplast DNA (cpDNA) microsatellites were typed the thermophilous angustifolia and ornus observed haplotypes geographic distribution of diversity compared to cpDNA data previously obtained more cold‐tolerant excelsior . found wide‐ranging haplotype sharing between phylogenetically close F. , suggesting hybridization (i) common glacial refuges Iberian Peninsula, northern...
Abstract Molecular forensic methods are being increasingly used to help enforce wildlife conservation laws. Using multilocus genotyping, illegal translocation of an animal can be demonstrated by excluding all potential source populations as individual's population origin. Here, we illustrate how this approach applied a large continuous defining the genetic structure and suspect animals from each identified cluster. We aimed test hypothesis that recreational hunters had illegally introduced...
Abstract Understanding adaptive genetic responses to climate change is a main challenge for preserving biological diversity. Successful predictive models climate-driven range shifts of species depend on the integration information adaptation, including that derived from genomic studies. Long-lived forest trees can experience substantial environmental across generations, which results in much more prominent adaptation lag than annual species. Here, we show candidate-gene SNPs (single...
Summary Wildfire is a major ecological driver of plant evolution. Understanding the genetic basis adaptation to wildfire crucial, because impending climate change will involve fire regime changes worldwide. We studied molecular serotiny, fire‐related trait, in Mediterranean maritime pine using association genetics. A single nucleotide polymorphism ( SNP ) set was used identify genotype : phenotype associations situ an unstructured natural population (eastern Iberian Peninsula) under...
