Drosophila pseudoobscura and D. persimilis are a sister species pair that have been used as model for studies of reproductive isolation speciation almost 100 years owing to their close evolutionary history, well characterized genetic differences, overlapping geographic distribution. There extensive analyses both pre- post-zygotic isolation, including courtship divergence, conspecific sperm precedence (CSP) how reinforcement by natural selection may or not act strengthen in sympatry. Post-zygotic explore the underlying mechanics isolation; inversions give rise initial events misexpression key genes typically found within inversion regions render hybrid offspring unfit inviable. We aim here present history between this pair, looking at field has developed over last century identifying open questions gaps literature.

Introduction Different ecotypes exhibit distinct life histories and occupy various environmental conditions for local adaptation. Coilia nasus , an anadromous fish, resides in offshore waters of the Pacific Northwest reproduces connected rivers lakes, including middle-lower Yangtze River. Populations C. have differentiated into two ecotypes: migratory landlocked. Methods This study examined spatiotemporal distributions these their habitats by analyzing DNA collected from Poyang Lake Tai during 2020–2021. Results A total 157 eDNA samples were obtained, with 62 yielding positive results, 23 39 Lake. The population exhibited seasonal movements Lake, entering River-Poyang channel spring, migrating southward summer, returning to autumn. In contrast, spatial distribution landlocked remained relatively stable throughout seasons. Partial least squares structural equation modeling (PLS-SEM) analysis indicated that patterns not significantly associated factors. was affected lower water turbidity reduced conductivity. Discussion findings suggest temporal variations primarily reflect its reproductive history. Conversely, resembles resident fish populations is mainly influenced a preference higher quality. results imply differences adaptation may contributed formation ecotypes. also shows effectiveness technology assessing dynamics.

Abstract In flowering plants, pollen-pistil interactions can serve as an important barrier to reproduction between species. As the last before fertilization, these reproductive organs are both complex and for determining a suitable mate. Here, we test whether differences in style length generate post-mating prezygotic mechanical five species of perennial Phlox wildflowers with geographically overlapping distributions. We perform controlled pairwise reciprocal crosses three long styles two short assess crossing success (seed set). find that heterospecific seed set is broadly reduced compared conspecific cross reveal striking asymmetry different lengths. To determine mechanism underlying this asymmetric isolating pollen tube growth vitro vivo . demonstrate tubes short-styled do not grow enough reach ovaries long-styled also have smaller within diameter highly correlated length. Our results support hypothesis small lacks resources access species, resulting asymmetrical, reproduction. Such mechanisms, combined additional incompatibilities, may be particularly closely related geographic proximity share pollinators.

Abstract Sperm morphology varies considerably among species. traits may contribute to speciation if they diverge fast in allopatry and cause conspecific sperm precedence upon secondary contact. However, their role driving prezygotic isolation has been poorly investigated. Here we test the hypothesis that, early process, female promiscuity promotes a reduction overlap length distributions songbird populations. We assembled data set of 20 pairs populations with known distributions, published estimate divergence time, an index derived from extrapair paternity rates or relative testis size. found that diverged more rapidly promiscuous Faster between was caused by lower variance trait species, not faster mean lengths. The reduced is presumably due stronger stabilizing selection on mediated competition. If divergent optima causes sympatry, which remains be shown empirically, promote isolation, rapid songbirds.

Abstract Postmating prezygotic (PMPZ) traits play an important role in mating success, especially species where gametes from multiple males compete. Despite this, the effect of system transitions, and attendant shifts intensity sexual selection, on specific PMPZ their underlying loci is still poorly understood. Here we assessed differences pollen tissue-specific gene expression (in leaf, pollen, style) between two closely related plant with different systems— Solanum lycopersicum (selfing) & pennellii (outcrossing). We focused known roles tube growth rate, including pectin methylesterases (PMEs) inhibitors (PMEIs), in- vitro in-vivo rates. Among observed species, found that domain pollen-biased genes was much narrower selfing S. compared to outcrossing , for most reproductive PMEs PMEIs.

Identifying the presence and strength of reproductive isolating barriers is necessary to understand how species form then remain distinct in face ongoing gene flow. Here we study isolation at two stages speciation process closely related mushroom-feeding Drosophila recens D. subquinaria. We assess three that occur after mating, including number eggs laid, proportion laid hatched, adult offspring from a single mating. First, all are present between females subquinaria males, which late but still produce fertile daughters through flow can occur. There no evidence for geographic variation any these traits, concurrent with patterns behavioral isolation. Second, strong geographically distant conspecific populations subquinaria, early show genetic differentiation asymmetric discrimination. The reduction asymmetric, consistent isolation, suggests evolution postmating prezygotic due cascade reinforcement against mating recens. In summary, not only may help maintain they also drive earliest within
