Interspecific Variations in Interplant Communication and Ecological Characteristics in Trees.

Plants evolve diverse communication systems in adapting to complex and variable environments. Here, we examined the relationship between plant architecture, population density and inter-plant communication within tree species. We tested the hypothesis that trees of species with complex architecture or high population density (high population density: HPD) communicate among conspecifics via volatiles.

Adaptive radiation of the genus in the Bonin Islands revealed through double-digest restriction site-associated DNA sequencing analysis.

The Bonin Islands, comprised of the Mukojima, Chichijima, and Hahajima Islands, are known for their isolated and distinctive habitats, hosting a diverse array of endemic flora and fauna. In these islands, adaptive radiation has played a remarkable role in speciation, particularly evident in the genus that is represented by three species: and exclusive to the Chichijima Islands, and , distributed across the entire Bonin Islands. Notably, exhibits multiple ecotypes, differing in leaf hair density, flowering time, and tree size.
