Multinational evaluation of genetic diversity indicators for the Kunming‐Montreal Global Biodiversity Framework

Ecology Letters, Journal Year: 2024, Volume and Issue: 27(7)

Published: July 1, 2024

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 feasibility requires addressing methodological challenges using data gathered from diverse sources, across taxonomic groups, countries varying socio‐economic biodiversity levels. Here, we assess 919 taxa, representing 5271 nine countries, including megadiverse developing economies. Eighty‐three percent taxa assessed had available calculate at least one indicator. Our results show although majority species most populations, 58% have too small Moreover, indicator values suggest IUCN Red List other initiatives fail status, highlighting critical importance indicators.

Incorporating Genetic Diversity to Optimize the Plant Conservation Network in the Third Pole

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(3)

Published: March 1, 2025

Climate change poses a significant threat to the survival of many species. Although protected areas can slow down biodiversity loss, they often lack systematic planning and do not integrate genetic diversity. Genetic diversity is key prerequisite for species ability tolerate new conditions. Using population distribution data from 96 plant in Third Pole (encompassing Tibetan Plateau adjacent mountains), we mapped patterns diversity, projected climate-driven range dynamics future erosion, designed an optimal conservation framework region. We identified several patches high haplotype (HD), with relatively number haplotypes southeastern Pole. Regression models revealed that climate topography have interacted shape latitude precipitation being best predictors HD cpDNA nrDNA, respectively. Ecological niche modeling predicted approximate 43 km northwestward 86 m upward shift suitable habitats under scenarios, likely leading loss up 13.19% 15.49% nrDNA Alarmingly, 71.20% newly priority fall outside existing planned National Park Clusters.

Analysis of future climate variability under CMIP6 scenarios based on a downscaling method considering wet days in the upper Yangtze River basin, China

Theoretical and Applied Climatology, Journal Year: 2025, Volume and Issue: 156(2)

Abstract According to recent studies, the past decade was hottest on record, and climate change is accelerating. As part of Yangtze River Basin, largest river basin in China, Upper Basin (UYRB) plays a crucial role as primary source hydropower. However, UYRB also one most climate-sensitive regions within basin, making impact this area particularly critical. We downscaled CMIP6 GCMs’ outputs precipitation (including wet/dry spells sequence correction), temperature projections (2024–2100), under four typical Shared Socioeconomic Pathways (SSPs), we pursued trend analysis upon these potential future series. found significant upward trends across all SSPs August, but no for same month. Additionally, SSP370 SSP585, there are December, while showed during that This may result drier winters than now, increased evapotranspiration, reduced surface (snow) water storage, impacting resources availability. Consecutive dry/wet days at station, scale show spatial-temporal heterogeneity, generally wet longer, dry shorten moving from South-East North-West.

DNA-based studies and genetic diversity indicator assessments are complementary approaches to conserving evolutionary potential

Conservation Genetics, Journal Year: 2024, Volume and Issue: 25(6), P. 1147 - 1153

Published: Aug. 21, 2024

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 the development advancement indicators a complementary approach studies in conservation biology, but not substitute. empirical data can different conserving diversity. affordable tracking, reporting, prioritization communication, although, being proxies, do comprehensive status Conversely, methods offer analysis given species or population, although they remain challenging implement most globally, current capacity resourcing. We conclude are both actions recommend be used combination monitoring

To halt the loss of biodiversity, collaboration among scientists, managers and decision-makers is vital. Although biodiversity a global problem, management actions influencing diversity are often on local to regional scale. Our study an example conservation genomic assessment developed in between scientists managers. We used 2bRAD sequencing assess 18 eelgrass (Zostera marina) meadows northwestern Sweden, area that has experienced large losses since 1980s. Genetic was comparable other assessed Atlantic, but order magnitude lower than Pacific. All one meadow showed high rates sexual reproduction. Almost all were divergent grouped into five genetic clusters. Four clusters correspond geographic regions can be define units. Meadows areas with decline 1980s 2020s more inbred increase eelgrass. Overall, our results indicate striving protect number within each cluster important for maintaining connectivity Sweden likely beneficial wider ecosystem. estimate current indicators essential variables discuss their challenges marine facultative clonal species. showcase how regional-scale assessments serve as foundation protection restoration priority

Genetic diversity is crucial to secure the survival and sustainability of ecosystems. Given anthropogenic pressure, as well projected alterations connected with level circulation water, riparian forests are particular concern. In this paper, we assessed genetic variation black poplar – one keystone tree species riverine forests. The natural habitats have been severely transformed leading a significant decline its population size. Using set 18 nuclear microsatellites geographic location data, studied 26 remnant populations (1,261 trees) located along biggest river valleys in Poland. Our main goal was assess overall verify if range fragmentation habitat transformation disrupted gene exchange among populations. Genotyping revealed that 261 trees were clones. clonality higher more sections. All probably gone through drastic bottleneck distant past, most them low effective sizes. Still, remains high, but certain require attention due their lower variation, strong spatial structure. differentiation low, yet Bayesian clustering supported existence 11 clusters. According results, prevalent between adjacent Relatively free flow occurs only Vistula, particularly middle section which characterized by highest variation. Noticeable structuring observed Oder. Populations at margin showed signs divergence reduction We conclude human activities impacted pool Poland disrupting landscape connectivity preventing from generative reproduction. study provides practical guidelines on how develop implement conservation program for It also presents case favoring renaturation monitoring, concerning species.
