Abstract Thuja plicata is a conifer tree that valued for its cultural, ecological and wood quality features in natural range western North America used Europe as an exotic timber species. It increasingly mixed species forests the UK are managed using regeneration, raising questions about genetic diversity of both adult trees offspring these stands. We studied population structure four woodlands adults naturally regenerated T. . discovered 194,154 Single Nucleotide Polymorphisms (SNPs) Genotyping-by-Sequencing (GBS) retained 655 SNPs across 598 genome sequence scaffolds analysis. The majority included only one SNP, suggesting that; selected were widely distributed within genome. found many monomorphic sites, most which restricted to single woodland, indicative differentiation among woodlands. three ancestral populations (K = 3) low levels admixture indicating starting materials largely from populations.

Cgsim: An R Package for Simulation of Population Genetics for Conservation and Management Applications

Wildlife conservation and management increasingly considers genetic information to plan, understand evaluate implemented population interventions. These actions commonly include translocation reductions through removals. Change in variation response can be unintuitive due the influence of multiple interacting drivers (e.g. drift, life history traits, environmental stochasticity). Simulation is an excellent tool predicted consequences different proposed or actions. However, simulators that are robust a wide variety traits also have steep learning curve appropriately parameterize common To fill this gap, we developed cgsim, R package for simulating interventions populations wildlife species. We set functions specifically effects four main aspects managing small, declining isolated populations: loss diversity augmenting existing translocation), reduction targeted removals catastrophes driven by stochastic extrinsic forces. Our single simulation model individual-based, flexible range traits. Here validate cgsim comparison simulations theoretical expectations illustrate its applied utility focusing on recently published empirical example Greater Sage-Grouse.

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

Molecular Ecology, Год журнала: 2025, Номер unknown

Опубликована: Март 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, Год журнала: 2025, Номер unknown

Опубликована: Март 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.
