Amazing article by @jamesnieh.bsky.social ! Looking forward to reading his new book- The Language of Bees!

Science needs failure
Perhaps “failure” is even too strong a term. Research takes different and unexpected paths, but when something goes fundamentally wrong, it can feel like a punch in the gut.

How do 🐝 evaluate costs & benefits of foraging w/in 🌸mimicry systems? Turns out 🐝 attend more to costs than to benefits, similar to animals in other contexts! For more, read our new pub in @behavecol.bsky.social ! doi.org/10.1093/behe... therusselllab.net/wp-content/u... @jentomology.bsky.social

Bees attend primarily to aversive costs, not pollen rewards, to avoid exploitation by floral mimics
We varied the benefits and costs of flower mimics and models (rewardless flowers and rewarding flowers, respectively) and investigated how bees responded.

Heard of the haplodiploid hypothesis (=¾ relatedness hypothesis)? It’s long been a staple of biology textbooks – you may’ve run into it in Intro Biology, Genetics, Evolution, or Behavior. It’s also been very influential on social evolution theory, yet surprisingly, it long remained untested.🧵
