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...
Societal Impact Statement Seedbanks are vital for biodiversity conservation, but their potential remains underutilised due to a limited understanding of the intraspecific genetic diversity they hold. By leveraging digitised data associated with seedbank collections, such as sampling locations, number maternal plants and seed traits, we can attempt estimation variation identify gaps in enabling better prioritisation species conservation efforts. These advancements inform policy targets like...
Abstract Effective population size ( N e ) is a pivotal evolutionary parameter with crucial implications in conservation practice and policy. Genetic methods to estimate have been preferred over demographic because they rely on genetic data rather than time‐consuming ecological monitoring. Methods based linkage disequilibrium (LD), particular, become popular as require single sampling provide estimates that refer recent generations. A software program the LD method, GONE, looks particularly...
Cyperus esculentus is widespread in tropical and temperate zones also present cooler regions. It used as a crop plant, but it occurs the wild weed. As consequence of its ecological plasticity, C. has remarkable variability, with several morphotypes. Four wild-type varieties are presently recognized, addition to cultivated form. This study investigates phylogenetic position biogeography objective contributing new data increase understanding evolutionary history.
Estimating effective population size (Ne) is important for theoretical and practical applications in evolutionary biology conservation. Nevertheless, estimates of Ne organisms with complex life-history traits remain scarce because the challenges associated estimation methods. Partially clonal plants capable both vegetative (clonal) growth sexual reproduction are a common group which discrepancy between apparent number individuals (ramets) genetic (genets) can be striking, it unclear how this...
Abstract Enabling food security requires access to a broad range of genetic resources facilitate crop breeding. This need is increased in climate change scenario, which will require the production novel crops adapted new conditions. However, many major have reduced diversity due bottlenecks that they experienced during their domestication and subsequent Crop wild relatives (CWRs) remain underexploited plant breeding programmes, mostly because lack knowledge cross-compatibility with crops. In...
Abstract Obtaining informative data is the ambition of any genomic project, but in nonmodel species with very large genomes, pursuing such a goal requires surmounting series analytical challenges. Double‐digest RAD sequencing routinely used organisms and offers some control over volume obtained. However, recovered not always an indication reliability sets, quality checks are necessary to ensure that true artefactual information set apart. In present study, we aim fill gap existing between...
Climate change poses a considerable challenge for coffee farming, due to increasing temperatures, worsening weather perturbations, and shifts in the quantity timing of precipitation. Of actions required ensuring climate resilience coffee, changing crop itself is paramount, this may have include using alternative species. In study we use multidisciplinary approach elucidate identity, distribution, attributes, two minor species from East Africa: Coffea racemosa C. zanguebariae . Using DNA...
In plants capable of clonal reproduction, demographic and ecological investigations are essential for understanding the factors contributing to population diversity. The perennial, orchid Cypripedium calceolus has a variable status in Europe Asia, being threatened with extinction some countries abundant others. Estonia, thriving populations can be observed different biogeographical regions. aim this study was characterize genetic diversity differentiation Estonian populations, by comparing...

Societal Impact Statement Digitized molecular data are vital to numerous aspects of scientific research and genetic resource use. The Convention on Biological Diversity currently refers this as “Digital Sequence Information” (DSI), a term not widely adopted by science lacking clear definition. There concerns over the access resources absence benefit sharing provider countries. Open DSI might exacerbate this, which is leading increasing policy interventions restricted DSI. We analyze current...

We test different methodological approaches clarify relationships hypothesize divergence times for section. The inferred phylogenetic hypothesis shows that is eastern Mediterranean western Asian in origin a clear East/West split occurred early diversification Several species are not sharply separated and, from morphological...
Abstract Ecologically dominant species are primary determinants of ecosystem function, especially in grassy ecosystems, but the history and biology ecosystems Madagascar poorly understood compared to those Africa. Loudetia simplex is a C4 perennial grass that adapted fire common across It also widespread central what often thought be human-derived grasslands, leading us question how recently L. arrived it spread Madagascar. To address this, we collected population genetic data for 11 nuclear...
Abstract The split between conservation science and real‐world application is an ongoing issue despite several calls for unification. Researchers are empowered to partially bridge the research‐implementation gap by making their findings more accessible. Cypripedium calceolus most recognizable orchid of European flora, currently facing habitat change fragmentation, in addition threats from collectors illegal traders. Although studies have focused on ecological genetic features species, a...
The present investigation investigated the genetic structure of a monophyletic group endemic species belonging to Genista ephedroides group: G. bocchierii, cilentina, demarcoi, dorycnifolia, ephedroides, gasparrinii, insularis, numidica, tyrrhena subsp. tyrrhena, pontiana and valsecchiae, all distributed in western Mediterranean. Using seven plastid microsatellites, 16 populations (288 individuals) were screened. Haplotype fixation was observed particular for most Tyrrhenian taxa (i.e....
