    • Rainfall seasonality predicts the germination behaviour of a tropical dry-forest vine 

      Martins, Adriana A.; Opedal, Øystein Hjorthol; Armbruster, William Scott; Pelabon, Christophe (Journal article; Peer reviewed, 2019)
      Seed dormancy is considered to be an adaptive strategy in seasonal and/or unpredictable environments because it prevents germination during climatically favorable periods that are too short for seedling establishment. ...
