Atmospheric CO2 forces abrupt vegetation shifts locally, but not globally.
Steven I. Higgins,Simon Scheiter +1 more
TL;DR: It is shown that tropical grassland, savanna and forest ecosystems, areas large enough to have powerful impacts on the Earth system, are likely to shift to alternative states, and increasing atmospheric CO2 concentration will force transitions to vegetation states characterized by higher biomass and/or woody-plant dominance.
Journal ArticleDOI
Predicting the Landscape‐Scale Distribution of Alien Plants and Their Threat to Plant Diversity
TL;DR: This paper used logistic regression models to predict the potential distribution of six important invasive alien plants in relation to several environmental variables and found that most alien species threaten more plant species than might be suggested by the area they are predicted to invade.
Ecology of invasive plants: state of the art.

TL;DR: A global database of 108753 trees for which stem diameter, height and crown diameter have all been measured is compiled and it is found that a single equation predicts stem diameter from these two variables across the world's forests.
Journal ArticleDOI
Three decades of multi-dimensional change in global leaf phenology
TL;DR: A comprehensive global assessment of vegetation phenology now shows that vegetation activity changed severely on 54% of the global land surface between 1981 and 2012, hindering understanding of Earth system dynamics as mentioned in this paper.
