Early land plants: Plentiful but neglected nutritional resources for herbivores? [PDF]
Ecol Evol, 2022 In this paper, we explore the unknown reason(s) why herbivores rarely seem to attack early land plants like mosses and ferns. Our study, in which we looked at the performance of an arthropod and a gastropod on 15 species of such plants, yields surprising results that disqualify some of the common notions about early land plants.
