Plastid sequences are a cornerstone in plant systematic studies and key aspects of their evolution, such as uniparental inheritance absent recombination, often treated axioms. While exceptions to these assumptions can profoundly influence evolutionary inference, detecting them require extensive sampling, abundant sequence data, detailed testing. Using advancements high-throughput sequencing, we analyzed the whole plastomes 65 accessions Picea, genus ∼35 coniferous forest tree species, test...
Summary Scots pine is the foundation species of diverse forested ecosystems across Eurasia and displays remarkable ecological breadth, occurring in environments ranging from temperate rainforests to arid tundra margins. Such expansive distributions can be favored by various demographic adaptive processes interactions between them. To understand impact neutral selective forces on genetic structure pine, we conducted range‐wide population analyses 2321 trees 202 populations using...
Hybridizing species such as oaks may provide a model to study the role of selection in speciation with gene flow. Discrete species' identities and different adaptations are maintained among closely related oak despite recurrent This is probably due ecologically mediated at few key genes or genomic regions. Neutrality tests can be applied identify so-called outlier loci, which demonstrate locus-specific signatures divergent candidate for further study.
Plant mitogenomes can be difficult to assemble because they are structurally dynamic and prone intergenomic DNA transfers, leading the unusual situation where an organelle genome is far outnumbered by its nuclear counterparts. As a result, comparative mitogenome studies in their infancy some key aspects of evolution still known mainly from pregenomic, qualitative methods. To help address these limitations, we combined machine learning silico enrichment mitochondrial-like long reads...
Summary Understanding the origin and distribution of genetic diversity across landscapes is critical for predicting future organisms in changing climates. This study investigated how adaptive demographic forces have shaped population structure Pinus densata , a keystone species on Qinghai‐Tibetan Plateau (QTP). We examined genomic range P. using exome capture sequencing. applied spatially explicit tests to dissect impacts allele surfing, geographic isolation environmental gradients...
The application of stable hydrogen isotope (δD) techniques has swiftly advanced our understanding animal movements, but this progression is dominated by studies birds and relatively long‐distance, north–south migrants. This dominance reflects the challenge incorporating multiple sources error into geographic assignments nature spatially explicit δD models, which possess greater latitudinal than longitudinal resolution. However, recent progress in likelihood‐based that incorporate isotopic...
Summary Stable hydrogen isotope (δD) methods for tracking animal movement are widely used yet often produce low resolution assignments. Incorporating prior knowledge of abundance, distribution or patterns can ameliorate this limitation, but data lacking most species. We demonstrate how observations reported by citizen scientists be to develop robust estimates species distributions and constrain δD developed a Bayesian framework refine isotopic migrant origins conditional on models...
Many birds have advanced their spring migration and breeding phenology in response to climate change, yet some long‐distance migrants appear constrained adjustments. In addition, bird species with long generation times those higher trophic positions may also be less able track climate‐induced shifts food availability. Migratory of prey therefore particularly vulnerable change because: 1) most are long‐lived relatively low reproductive capacity, 2) many feed predominately on insectivorous...
Oaks (Quercus: Fagaceae) commonly interbreed yet retain their morphological, genetic and ecological distinctiveness. Post-zygotic isolation mechanisms, such as ecologically dependent selection on adaptive loci, may therefore limit introgression. To test this hypothesis, we quantified hybridization divergence across the contact zone of four red oaks (Quercus section Lobatae) in Great Lakes region North America using a suite 259 amplified fragment length polymorphisms 27 genic genomic...
Taxonomic relationships between North American red oak species (Quercus section Lobatae) are not well resolved using genetic and morphological markers. Phenotypic plasticity, recent divergence, hybridization may all contribute to the unclear boundaries in oaks. We applied twenty-eight genomic gene-basedmicrosatellites, including outlier loci with potential roles reproductive isolation adaptive divergence species, natural populations of four monophyletic interfertile species: Quercus...

Abstract Conserving biodiversity is a global imperative, yet our capacity to quantify and understand species occurrences has been limited. To help address this challenge, we develop novel monitoring approach based on deep sequencing of airborne eDNA. When applied 34-year archive weekly filters from an aerosol sampling station in northern Sweden, methods enabled robust detection over 2,700 genera across all domains life estimates eDNA catchment areas. Reconstructed time series revealed...

Abstract Non-invasive sampling is an important development in population genetic monitoring of wild animals. Particularly, the collection environmental DNA (eDNA) which can be collected without needing to encounter target animal, facilitates analysis cryptic and threatened species. One method that has been applied these types sample capture enrichment overcomes issue high proportions exogenous (non-host) from lower quality samples. We tested whether mitochondrial sampled feeding traces...
