Effects of environment, life-history and phylogeny on germination strategy of 789 angiosperms species on the eastern Tibetan Plateau

Germination strategies vary widely among species and significantly influence individual fitness and community diversity. Germination strategies are known to be influenced by environmental conditions, life-history traits and evolutionary history, but how these factors influence germination across spe...

Germination strategies are known to be influenced by environmental conditions, life-history traits and evolutionary history, but how these factors influence germination across species under natural conditions is poorly understood.
