Science magazine front cover. Picture of a walnut in its opened shell. The text reads "All about timing. Mating type evolution in walnuts and pecans" graphical abstract:
"In Juglans (top left) and Carya, two morphs show complementary temporal separation between male and female flowering (heterodichogamy). Mating types are controlled by two nonhomologous single-locus mechanisms that arose in the common ancestor of each genus, respectively. (Bottom left) Simplified schematic of a putative functional regulatory element at the Juglans locus. (Bottom right) Strong genotypic correlations across the Carya locus indicate a lack of recombination between two colinear haplotypes with similar gene content."

A giant snapping turtle moves across a field, with a lump of dirt on her back that has green grass growing on it.  It's comically oversized, flat on top.  Behind the turtle is what looks like a bit of forest with dry lake in the foreground, and some shore grasses in between.
