A large English population of the temperate tuberous Greater Butterfly-orchid, Platanthera chlorantha, was monitored through a 16-year period. Each June number flowering plants counted and 60 were measured in situ for four morphological traits, selected both ease measurement their contrasting contributions to life history species. Trait data tested annually pairwise combinations individual plants, before mean values throughout study period regressed cross-correlated against each other local meteorological parameters. Labellar spur length proved be more constrained than either flower or stem height, rarely yielded statistically significant correlations with whereas three remaining traits reliably showed modest but correlations. Mean coefficients variation differed only modestly among years few any meaningful trends. Spring rainfall insolation had no detectable effect on that June; instead, they impacted trait expression during following year, presumably as result differential resourcing replacement tubers formed previous year. High spring year t-1 increased leaf area height t, widely fluctuating highest immediately those characterised by relatively dry and/or sunny springs.

However, the molecular basis of traits unclear. Here, compared with wild citrus species/ ‐related genera, content 43 bioactive metabolites their derivatives increased pummelo. Furthermore, we assembled genome sequence variety purposes long history, ‘Huazhouyou‐tomentosa’ (HZY‐T), at chromosome level size 349.07 Mb.

Using metabolome transcriptome six developmental stages HZY‐T ‘Huazhouyou‐smooth’ (HZY‐S) fruit peel, generated regulatory networks derivatives. We identified novel MYB transcription factor, CmtMYB108, as regulator flavone pathways. Both mutations expression CmtMYB108 , which targets genes PAL phenylalanine ammonia‐lyase FNS synthase ), displayed differential between species.

Abstract Background and Aims Biogeographical relationships between the Canary Islands north-west Africa are often explained by oceanic dispersal geographical proximity. Sister-group Canarian eastern African/Arabian taxa, ‘Rand Flora’ pattern, rare among plants have been attributed to extinction of north-western African populations. Euphorbia balsamifera is only representative species this pattern that distributed in Africa; it also one few present all seven islands. Previous studies placed populations E. as sister populations, but relationship was based on herbarium samples with highly degraded DNA. Here, we test hypothesis sampling new continental populations; expand examine dynamics island colonization diversification. Methods Using target enrichment genome skimming, reconstructed phylogenetic within its disjunct relatives. A single nucleotide polymorphism dataset obtained from sequences used infer population genetic diversity patterns. We convolutional neural networks discriminate alternative scenarios. Key Results The results confirmed Rand Flora sister-group western adenensis Eritreo-Arabian region recovered an eastern–western structure Convolutional supported a scenario east-to-west colonization, followed extinctions Lanzarote Fuerteventura recolonization Tenerife Gran Canaria; signal admixture recovered.

The narrow-headed vole, collared lemming and common vole were the most abundant small mammal species across Eurasian Late Pleistocene steppe-tundra environment.

Urbanization is hypothesized to isolate populations and restrict dispersal, leading reduced genetic diversity increased differentiation. We tested this hypothesis in specialist herbivorous insects of milkweed, positing that higher dispersal ability would mitigate the negative effects urbanization on drift gene flow, these vary with city size. In study, we collected 383 milkweed from urban rural sites Toronto, Canada, five surrounding cities. Using ddRADseq, generated 145,000 SPNs for monarchs, 10,000 SNPs beetles, 6,000 weevils quantify diversity, demographic history population structure. Contrary our hypotheses, results indicated no effect or Genetic measured as π, varied between 0.0013 0.0044 across species, vs. component, but monarchs having >2 X compared beetles weevils. Similarly, differentiation was generally low, FST varying 0.01 0.28, there are consistent trends among samples any three species. However, analyses revealed a decline effective size all sampled beginning around last glacial maximum intensifying over past 1,000 years. Our findings suggest both have not been major factor reducing flow increasing milkweed's insect populations. Instead, historical events such climatic change since maximum, large-scale anthropogenic disturbance general, had more pronounced impact demography. These highlight importance considering combined natural long-term processes when studying genetics context urbanization.

Abstract Today, sustainable water use has become a critical policy area, as dynamics such increasing global demand, scarcity, and climate change directly affect agricultural production. In this study, the role of psychological social factors in explaining water-saving behaviors production was examined based on Norm Activation Model (NAM); model extended with environmental concern (EC) variable. Within scope field study carried out Konya province, relationships between farmers' "Awareness Results", "Situational Responsibility", "Effectiveness Outputs", "Ability", "Guilt", "Pride" emotions personal norms (PN) effect PN saving (WCB) were measured. addition, direct indirect effects EC both WCB analyzed. Structural equation modeling performed using SmartPLS revealed that NAM increased its explanatory power by approximately 2.5% compared to original model. The findings show determining support efficient plays an essential individual behavioral changes developing strategic recommendations for policymakers. points sensitivity normative approaches should be taken into account interventions aimed at sustainability management policies irrigation practices.

Abstract Understanding the importance of ligand patterning in biological processes requires precise control over molecular positioning and spacing. While DNA origami structures offer nanoscale precision biomolecule arrangement, their applications are limited by challenges related to structural stability, scalability, surface area. Here, we present a straightforward rapid stamping technique for transferring oligonucleotide patterns onto surfaces, visualized using DNA-PAINT super-resolution microscopy quantitatively assess efficiency across different stamp types. Unlike traditional top-down methods that require specialized equipment, our provides an accessible, self-assembled platform patterning, with versatility various substrates via modifiable pattern-transfer oligonucleotides. We demonstrate reliable, efficient, pattern transfer at single-molecule resolution, enabling new opportunities study distance-dependent processes, including receptor activation, multivalent binding, enzymatic cascades broader spatial scales detection techniques. The use passivated limits non-specific interactions unpatterned areas enables interaction between target patterned biomolecules. Our method advances combining nanotechnology imaging techniques, expanding access cost-effective analytical approaches potentially multiplexed live measurements.
