Insights into the evolutionary history and widespread occurrence of antheridiogen systems in ferns. [PDF]
New Phytol, 2021 Summary Sex expression of homosporous ferns is controlled by multiple factors, one being the antheridiogen system. Antheridiogens are pheromones released by sexually mature female fern gametophytes, turning nearby asexual gametophytes precociously male. Nevertheless, not all species respond. It is still unknown how many fern species use antheridiogens,

Edaphic heterogeneity and the evolutionary trajectory of Amazonian plant communities. [PDF]
Ecol Evol, 2021 We investigated the phylogenetic structure of Amazonian fern and palm communities on edaphically distinct sites. We show that phylogenetic community structure varies along a soil base cation concentration gradient within non‐inundated Amazonian rain forests.
