"Exotic species are a big problem worldwide. While the mechanisms of invasion vary from one exotic species to the next, researchers can tease out patterns that are useful for understanding and ultimately managing invasion. A new study published in the Journal of Biogeography reveals how one team has applied an emerging method known as the phylogenetic field approach to do just that for exotic plants in Japan. The results offer critical insight into how ecology and evolution influence the dynamics of invasion. Darwin’s On the Origin of Species marked the first time biological invasion had been addressed using the principles of evolutionary ecology. But followed to their logical end, these principles yielded two contradictory hypotheses. The pre-adaptation hypothesis states that exotic species successfully colonize assemblages with native species that are ecologically similar because both require the same set of environmental conditions to thrive..."

"Giant clams are keystone species of coral reef ecosystems. Like coral, giant clams harbor a vibrant community of algae and bacteria. But unlike coral, little is known about how these microorganisms help giant clams thrive or cause them to perish. To find out, authors of a new study placed giant clams in aquariums with one or two species of coral. DNA profiling revealed that the clams were home to three distinct varieties of microbial communities, or “microbiotypes”. Interestingly, these microbiotypes weren’t altered by changes in water temperature or by the type of coral species placed near clams. But dying clams did show one trait in common—an overwhelming presence of bacteria from the vibrionaceae family, which in humans are usually associated with infection from eating undercooked seafood. What’s more, clams died most frequently around coral of the species Acropora cytherea. That suggests that Acropora cytherea could make giant clams susceptible to infection by vibrionaceae bacteria..."
