Evolution of fruit and seed traits during almond naturalization
Journal of Ecology, Volume 110, Issue 3, Page 686-699, March 2022., 2022 Almond naturalization is consistent with strong directional selection on fruits and seeds, leading to smaller and more toxic seeds encased in harder endocarps. Accordingly, we propose that feralization of this crop is, at least to some degree, driven by adaptive evolution of dispersal and recruitment traits.

Ecology and Evolution, Volume 12, Issue 2, February 2022., 2022 Frogs have evolved terrestrial eggs many times, offering an excellent opportunity to assess traits that may facilitate aquatic‐to‐terrestrial transitions. Our results suggest the importance of physiological adaptations and physiological plasticity during early life stages, specifically the early onset of urea excretion, its upregulation under dry ...
