Dry Climate Filters Gymnosperms but Not Angiosperms through Seed Mass
In the context of climate change in recent years, the fate of woody plant seed has an important impact on forest regeneration. Seed mass is an important reproductive strategy of plants. There are huge differences between gymnosperms (mainly conifers) and
