...), Jamaican endemic taxa that challenge the rule that bird speciation cannot progress in situ on small islands. Our analysis shows that divergent selection acting on male bill color, a sexual ornament that is red in polytmus and black in scitulus, acts as a key reproductive barrier. We...

..., in the Ogasawara Islands, an oceanic archipelago in Japan. We find that limb length is correlated with variation in habitat structure across the islands in male lizards, but not in female lizards. We suggest that the resulting variation in sexual dimorphism is driven by exploitation of the available niche space...

... panicle density exists below which seed production decreases substantially. Practitioners should assess relative panicle density at donor sites when creating seed collection plans and may consider sites with low panicle density as priority augmentation targets. abundant center model barrier islands...

... Baker’s law posits that self-fertilization facilitates colonization, a key concept for understanding population dynamics and the evolution of sexual systems in plants. However, the prevalence of dioecious species (those with separate sexes) on oceanic islands presents a notable exception to this law...

Population genetic structure was largely consistent with the distribution of contemporary sky islands and an isolation-by-distance effect, as indicated by hierarchical analyses of molecular variance and Mantel tests, respectively. Although global cooling during the Last Glacial Maximum...

Quartz fields present specialised patchy habitats with an island-like distribution in the landscape. Oophytum oviforme grows in the south-western part, whereas O. nanum covers most...

... were more likely to be found on islands compared to non-polymorphic species. Overall, our results indicate that the association between colour polymorphism and geographic range size may not exist among web-building spiders, or be as pronounced as in other lineages. This suggests that the strength...

... regions of elevated differentiation, including a locus that may be related to each subspecies’ distinctive coat pigmentation pattern. We investigated these regions as candidate speciation islands. However, we observed no significant reduction in gene flow in these regions, nor any indications of selection...

.... Abstract The ecological and phenotypic diversity observed in oceanic island radiations presents an evolutionary paradox: a high level of genetic variation is typically required for diversification, but species colonizing a new island commonly suffer from founder effects. This reduction in population size...

The challenges posed by these termites could be especially worrying in island ecosystems. Hence, it is crucial to implement early warning systems and monitoring programs in regions...

Our study contributes to the emerging body of literature showing differentiation in genes related to bird coloration, which may mediate prezygotic isolation, before speciation is complete. Figure 1.
