The process of plant speciation often involves the evolution of divergent ecotypes in
response to differences in soil water availability between habitats. While the same set of traits
is frequently associated with xeric/mesic ecotype divergence, it is unknown whether those
traits evolve independently or if they evolve in tandem as...

The cultivated strawberry, Fragaria Xananassa, is one of the youngest domesticated plants.

His 1766 “Natural History of Strawberries” is an extraordinary work...
While there is a persistent inverse relationship between latitude and species diversity across many taxa and ecosystems, deviations from this norm offer an opportunity to understand the conditions that contribute to large-scale diversity patterns. Marine systems, in particular, provide such an opportunity, as marine diversity does not always follow a...
