Ecological divergence in the silver moss Bryum argenteum: developmental, ontogenetic and life‐history trait variations across contrasting tropical ecosystems

open access: yesPlant Biology, EarlyView.
Ecotypes of the cosmopolitan moss Bryum argenteum differ markedly in growth, reproductive timing, and allocation across contrasting tropical ecosystems. These patterns reveal strong environment‐ and sex‐dependent life‐history strategies, highlighting the species as a model for studying ecological divergence in bryophytes.
