A review of plant phenolics and endozoochory
Ecology and Evolution, Volume 14, Issue 9, September 2024.Phenolic compounds, vital secondary metabolites in plants, evolved to protect against UV radiation and oxidative stress during their transition to terrestrial environments. In modern plants, phenolics serve primarily as defense mechanisms against pathogens and herbivores, while also influencing seed dormancy and viability.

Season, prey availability, sex, and age explain prey size selection in a large solitary carnivore
Ecology and Evolution, Volume 14, Issue 3, March 2024.Season, prey availability, and age influence the size of prey selected by pumas across six sites in North and South America. The optimal prey size for pumas appears context‐dependent, although evidence suggests it is smaller than predicted by ecological theory.
