    Leaf:wood allometry and functional traits explain variation in growth rate of rainforest trees

    Plant growth rates drive ecosystem productivity and are a central element of a species’ ecological strategy. For seedlings grown under controlled conditions, a large body of scientific literature has identified the functional traits responsible for driving interspecific variation in growth rate. However, the chief drivers of adult growth rates under field conditions are surprisingly little […] More

    Evolutionary constraints on disparity of ericaceous pollen grains

    Flowering plants show a high diversity of pollen morphology. This diversity is assumed to reflect not only variations in the underlying design, but also stress imposed by ecological conditions related to pollen survival and germination. Both components are expected to constrain accumulation of pollen disparity. Yu et al. perform a combination of phylogeny-based and statistical […] More
