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.

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.

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.

The Amphibian Genomics Consortium: advancing genomic and genetic resources for amphibian research and conservation

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Amphibians represent a diverse group of tetrapods, marked by deep divergence times between their three systematic orders and families. Studying amphibian biology through the genomics lens increases our understanding features this animal class that other terrestrial vertebrates. The need for genomic resources is more urgent than ever due to increasing threats group. are one most imperiled taxonomic groups, with approximately 41% species threatened extinction habitat loss, changes in land use patterns, disease, climate change, synergistic effects. Amphibian have provided better ontogenetic diversity, tissue regeneration, life history reproductive modes, antipredator strategies, resilience adaptive responses. They also serve as essential models studying broad traits, such evolutionary genome expansions contractions, they exhibit widest range sizes among all taxa possess multiple mechanisms genetic sex determination. Despite these features, sequencing amphibians has significantly lagged behind vertebrates, primarily challenges assembling large, repeat-rich genomes relative lack societal support. emergence long-read technologies, combined advanced molecular computational techniques improve scaffolding reduce workloads, now making it possible address some challenges.

ABSTRACT Global inequality rooted in legacies of colonialism and uneven development can lead to systematic biases scientific knowledge. In ecology evolutionary biology, findings, funding research effort are disproportionately concentrated at high latitudes, while biological diversity is low latitudes. This discrepancy may have a particular influence fields like phylogeography, molecular conservation genetics, where the rise genomics has increased cost technical expertise required apply state‐of‐the‐art methods. Here, we ask whether fundamental biogeographic pattern—the latitudinal gradient species richness tetrapods—is reflected available reference genomes, an important data resource for various applications tools biodiversity conservation. We also sequencing approaches differ between South North, reviewing last 5 years genetics four leading journals. find that extant genomes scarce relative latitudes reduced representation whole‐genome applied taxa North. conclude with recommendations close this gap improve international collaborations genomics.

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.
