Reed Canarygrass (RCG) is an aggressive invader in aquatic ecosystems that swiftly modifies the environment and decreases biodiversity. A physical model was used to investigate the mechanisms by which RCG spreads. Experimental trials were implemented to examine feedbacks between a mid-channel patch of the flexible RCG, hydraulics, and bedform evolution...

Rubus seed characteristics; seed coat morphology, anatomy, germination requirements and dormancy were studied in order to define protocols for breaking seed dormancy. Morphological analysis of the seed coat (testa) using scanning electron microscopy (SEM) included 56 seed accessions of 10 subgenera preserved in the collections of the US Department of...
