Irruption of herbivore populations due to the extirpation of predators has led to dramatic changes in ecosystem functioning worldwide. Herbivores compete with other species for their primary source of nutrition, plant biomass. Such competition is typically considered to occur between species in closely related clades and functional groups but could also occur with detritivores that consume senescent plant biomass. In this stud...

Environmental forces and biotic interactions, both positive and negative, structure ecological communities, but their relative roles remain obscure despite strong theory. For instance, ecologically similar species, based on the principle of limiting similarity, are expected to be most competitive and show negative interactions. Specious communities that assemble along broad environmental gradients afford the most power to test...

For the majority of plant species in the world, we know little about their functional ecology, and not even one of the most basic traits—the species’ growth habit. To fill the gap in availability of compiled plant growth‐form data, we have assembled what is, to our knowledge, the largest global database on growth‐form as a plant trait. We have, with extensive error checking and data synthesis, assembled a growth‐form database...

The leaf economics spectrum (LES) has revolutionized the way many ecologists think about quantifying plant ecological trade‐offs. In particular, the LES has connected a clear functional trade‐off (long‐lived leaves with slow carbon capture vs. short‐lived leaves with fast carbon capture) to a handful of easily measured leaf traits. Building on this work, community ecologists are now able to quickly assess species carbon‐captur...
