Effects of ambient climate and three warming treatments on fruit production in an alpine, subarctic meadow community
Premise Climate change is having major impacts on alpine and arctic regions, and inter‐annual variations in temperature are likely to increase. How increased climate variability will impact plant reproduction is unclear. Methods In a 4‐year study on fruit production by an alpine plant community in n...
