🕷️Warming increased predator abundance, but only reduced decomposition via trophic cascades at low arthropod diversity. High arthropod diversity weakened top-down effects and maintained detritivore abundance and decomposition👇

Social norms are unwritten rules backed by social sanctions. If child sexual abuse isn’t met with strong, collective consequences, we don’t have a social norm against it.

Yes, we CAM! First evidence of CAM photosynthesis in a carnivorous plant
Evidence for weak, facultative CAM is reported for the first time in a carnivorous plant, i.e., in Mexican representatives of Pinguicula (Lentibulariaceae).

Oh, I love this. A new species of sea anemone was discovered recently that parks itself on top of a hermit crab shell like a hat. It seems to feed partly off the crab's faeces, but it also excretes a hard shell that extends the crab's home. In return, it's carried around the seafloor like a king.
