Redlisting genetics: towards inclusion of genetic data in IUCN Red List assessments

Conservation Genetics, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 10, 2025

Abstract Genetic diversity is critical for adaptation in response to changing environments and provides a valuable metric predicting species’ extinction risk. The International Union Conservation of Nature (IUCN) broader scientific community have acknowledged that genetic component biodiversity conservation. However, there remain gaps the incorporation or application data risk assessments. Here, we describe how metrics can inform species Specifically, focus on information gained from metrics, temporal reporting changes complement existing IUCN Red List Threatened Species criteria. We conclude by advocating standardized sequence calculated facilitate use threat assessments List-assessed species. This perspective highlights need for, step towards, integration into expect our recommendations will ongoing work Survival Commission’s Genetics Specialist Group protect globally.

Toward a Global Science of Conservation Genomics: Coldspots in Genomic Resources Highlight a Need for Equitable Collaborations and Capacity Building

Molecular Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: March 17, 2025

ABSTRACT Advances in genomic sequencing have magnified our understanding of ecological and evolutionary mechanisms relevant to biodiversity conservation. As a result, the field conservation genomics has grown rapidly. Genomic data can be effective guiding decisions by revealing fine‐scale patterns genetic diversity adaptation. Adaptive potential, sometimes referred as is particularly informative for due its inverse relationship with extinction risk. Yet, global coldspots resources impede progress toward goals. We undertook systematic literature review characterise distribution amphibians reptiles relative species richness, IUCN status, predicted change. classify scope available their potential applicability Finally, we examine collaborations studies. Our findings underscore current priorities expanding resources, especially those aimed at predicting adaptive future environmental results also highlight need improved research, resource sharing, capacity building Global South.

The current status of genetic monitoring in conservation introductions

Conservation Science and Practice, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

Abstract Conservation introductions, translocating species beyond their native range, are increasingly necessary. Because genetic diversity is essential for to respond novel environments, understanding whether establishing populations can maintain crucial the long‐term success of conservation introductions. Using a systematic review, we quantified introductions globally and assessed monitoring occurring. We found that, despite extensive discussion, were rare. Of 167 examples, most performed in North America, Australia, China, with megadiverse developing nations underrepresented. Plants disproportionately represented (74%), climate change was primary motivator (40%). Survival reproduction frequently measured outcomes (71% 37%, respectively). Ten works (5.9%) reported monitoring, which only two considered temporal data showed worrying trend rapid negative post‐establishment. With limited evidence, it remains unclear establish self‐sustaining populations. As these translocations may be option some species, recommend practitioners trial assess maintenance founding inbreeding. Only through scientifically derived applications will learn how an uncertain future.

Identification of genetic diversity of Bufo gargarizans and Pelophylax nigromaculatus in the three islands of Chongming insights into aquaculture resources protection

Journal of the World Aquaculture Society, Journal Year: 2025, Volume and Issue: 56(2)

Published: April 1, 2025

Abstract Creatures grown on the island are more susceptible to genetic vulnerabilities because of their isolated nature and often limited diversity. Understanding structure these populations is crucial for effective conservation strategies, especially species that commonly found in aquaculture may inhabit islands. Bufo gargarizans Pelophylax nigromaculatus were distributed Chongming Islands Shanghai, China. We analyzed mitochondrial DNA cytochrome b ( cytb ) D‐loop sequences two across three islands investigate diversity, phylogenetics, infer historical demography, which indicated a lower diversity compared with mainland counterparts, reflecting heightened vulnerability environmental perturbations potential extinction risks. Noticeably, interlaced pattern was determined P. than B. , probably attributed differences species' dispersal capabilities among mainland. Hence, analyses propose targeted recommendations situ management.

On the potential for GWAS with phenotypic population means and allele-frequency data (popGWAS)

Peer Community Journal, Journal Year: 2025, Volume and Issue: 5

It is vital to understand the genomic basis of differences in ecologically important traits if we are impact global change on biodiversity and enhance our ability for targeted intervention. This study explores potential a novel genome-wide association (GWAS) approach identifying loci underlying quantitative polygenic natural populations, based phenotypic population means allele frequency data as obtained e.g. by PoolSeq approaches. Extensive genetic forward simulations demonstrate that generally effective oligogenic moderately relatively insensitive low heritability. However, applicability limited highly architectures pronounced structure. The required sample size moderate with very good results being already few dozen populations scored. When combined machine learning feature selection, method performs well predicting means. efficiency method, particularly when using pooled sequencing bulk phenotyping, makes GWAS studies more accessible research genomics. Moreover, direct comparison individual GWAS, proposed performed constistently better regard number true positive identified prediction accuracy. Overall, this highlights promise popGWAS dissecting complex populations.
