Scale-dependent effects of host patch traits on species composition in a stickleback parasite metacommunity.

abstract：:Plant reproductive phenology-the timing of reproduction-is shifting rapidly with global climate change. Many studies focus on flowering responses to climate, but few investigate how postflowering processes, such as how quickly plants develop from flowering to seed dispersal, respond to environmental factors.
