Wendy Valencia is the epitome of the 21st century naturalist. She enriches our community with her sensibility to natural phenomena and generosity. Looking forward to reading this highly integrative study about cycads pollination!
Wendy Valencia-Montoya and team uncover thermal infrared as one of the most ancient pollination signals uniting plants and animals. From the field to single proteins.

7/9 Wheatear coloration thus illustrates that by a modular architecture phenotypes can be decoupled within the constraints of a monogenic architecture, provided enough time for recombination. In this context, hybrid zones represent important melting pots for evolutionary tinkering.
