  • Feeding worker and queen

    Social evolution: honey bee nurse workers rear larvae as either new queens or new workers

  • Sea Anemone

  • Larix siberica

    Siberian Larch, taken at our field site near Lake Khovsgol in north-central Mongolia.  We are analyzing tree-ring width and stable isotopes of the tree rings to reconstruct climate, and Larch responses to climate change, over the past century as the temperature in Mongolia has risen.  

  • Sensation

    The sensations of pain, itch, and touch using genetics and neurobiology.

  • Porphyrogenes peterwegii

     Pupa of the butterfly Porphyrogenes peterwegii "peering" out of its leafy nest with false eyes, which in turn mimic the eyes of a snake, thereby protecting the pupa from small feather-brained  birds.
