General laws of biodiversity: Climatic niches predict plant range size and ecological dominance globally | PNAS
A longstanding question in ecology asks whether or not species that achieve large
geographic ranges also have large climatic niche breadths. Using ...

V. pleased to have this out in Ecology @esajournals.bsky.social - evidence for limiting similarity vs. pre-adaptation (Darwin's naturalisation conundrum) vary across very fine spatial scales and when using phylogenetic vs. functional metrics!

Evidence for environmental filtering and limiting similarity depends on spatial scale and dissimilarity metrics
Darwin's theory of natural selection provides two seemingly contradictory hypotheses for explaining the success of biological invasions: (1) the pre-adaptation hypothesis posits that introduced speci....

DYK mussels use a lifelike lure to attract fish, which are hosts for their parasitic larvae?
