So this came online over the weekend: My dive into the "definition" of coevolution is online ahead of publication in @journal-evo.bsky.social!
Don’t ask "when is it coevolution?" — ask "how?"

Abstract. Coevolution has come to be widely understood as specific, simultaneous, reciprocal adaptation by pairs of interacting species. This strict-sense

Interested in #virulence? Not sure what it is - or how to explain it? Just curious? 🧐🦠🧬🦋
@kayla-king.bsky.social and I just wrote a Primer for @currentbiology.bsky.social on the ecology and evolution of virulence!

Complex interactions in the life cycle of a simple parasite shape the evolution of virulence
Author summary Classical expectations on parasite evolution assume a trade-off between transmission rate and harm to the host (virulence), favoring parasites with intermediate virulence. However, rece...

Rising ocean acidity could reduce populations of phytoplankton, which may exacerbate climate warming.
More carbon dioxide in oceans could harm carbon-eating microbes, speed climate change
