Responses of two understory herbs, <i>Maianthemum canadense</i> and <i>Eurybia macrophylla</i>, to experimental forest warming: Early emergence is the key to enhanced reproductive output

Global warming might improve fitness of herbaceous species in deciduous forests, mainly by advancing their spring emergence. However, other impacts of global warming such as drier soils in the summer might partly reduce the carbon gain associated with early emergence.
