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 approaches that allow controlling for them. Considering current unprecedented rate diversity species loss, we expect our novel interpretive framework lags stimulate further research discussion most appropriate analyse conservation.

Genetic diversity is a prerequisite for evolutionary change in all kinds of organisms. It generally acknowledged that populations lacking genetic variation are unable to evolve response new environmental conditions (e.g., climate change) and thus may face an increased risk extinction. Although the importance incorporating into design conservation measures now well understood, less attention has been paid distinction between neutral (NGV) adaptive (AGV) variation. In this review, we first focus on utility NGV by examining ways quantify it, reviewing applications infer ecological processes, exploring its designing plant species. Against background, then summarize identify estimate AGV discuss potential use conservation. After comparing considering their pros cons context, conclude there urgent need better understanding role adaptation. To date, however, only few studies non-model species aimed at deciphering genomic basis complex trait Therefore, researchers practitioners should keep utilizing develop relevant strategies rare endangered until more estimates available.

Abstract Measuring genetic diversity of wild species using DNA-based data remains resource intensive and time consuming for nearly all species. However, assessments are needed global conservation commitments, including the Convention on Biological Diversity, governments managers to evaluate progress, as well prioritizing populations preserve recover (e.g., via rescue). Recently, indicators were developed tracking reporting status trends hundreds The quantify two simple proxies within-population among-population adaptive potential: small effective population size (Ne < 500) loss genetically distinct populations. must balance scientific credibility, practicality, simplicity. In present article, we summarize advantages these pragmatic indicators, address critiques by scientists simplifying assumptions policymakers complexity, propose potential solutions next steps.

How populations adapt to their environment is a fundamental question in biology. Yet, we know surprisingly little about this process, especially for endangered species, such as nonhuman great apes. Chimpanzees, our closest living relatives, are particularly notable because they inhabit diverse habitats, from rainforest woodland-savannah. Whether genetic adaptation facilitates habitat diversity remains unknown, despite it having wide implications evolutionary biology and conservation. By using newly sequenced exomes 828 wild chimpanzees (388 postfiltering), found evidence of fine-scale habitat, with signatures positive selection forest the same genes underlying malaria humans. This work demonstrates power noninvasive samples reveal adaptations highlights importance adaptive chimpanzees.
