Shade Tolerance, a Key Plant Feature of Complex Nature and Consequences
Understanding differential competitive potentials among co-occurring species mediated by shade tolerance is critical to predict ecosystem responses to global change drivers such as elevated CO2, climate change and the spread of invasive species. Expand
Tolerance to shade, drought, and waterlogging of temperate northern hemisphere trees and shrubs
Common scales of shade, drought, and waterlogging tolerance for 806 North American, European/West Asian, and East Asian temperate shrubs and trees were constructed to test the hypotheses that shade tolerance is negatively related to drought andWaterlogging tolerances, and that these correlations vary among continents and plant functional types. Expand
Refining the stress-gradient hypothesis for competition and facilitation in plant communities
The extension of the SGH presented here provides specific and testable hypotheses to foster research and helps to reconcile potential discrepancies among previous studies. Expand

A toolbox with definitions of key theoretical elements and a synthesis of the current understanding of the molecular and genetic mechanisms underlying plasticity relevant to climate change is provided to provide clear directives for future research and stimulate cross-disciplinary dialogue on the relevance of phenotypic plasticity under climate change. Expand
Novel ecosystems: theoretical and management aspects of the new ecological world order
We e xplore the issues relevant to those types of ecosystems containing new combinations of species that arise through human action, environmental change, and the impacts of the deliberate and… Expand
Plastic Phenotypic Response to Light of 16 Congeneric Shrubs From a Panamanian Rainforest
Investigation of tropical rainforest shrubs on Barro Colorado Island found a significant correlation between phenotypic plasticity and habitat affiliation, but phylogeny was not correlated with plasticity or with plant performance in any given PPFD treatment, reinforcing the hypothesis that phenotypesic plas- ticity has evolved through natural selection in this diverse genus. Expand
Quantitative estimation of phenotypic plasticity : bridging the gap between the evolutionary concept and its ecological applications
An alternative approach to quantify PP based on phenotypic distances among individuals of a given species exposed to different environments is summarized in a relative distance plasticity index (RDPI) that allows for statistical comparisons of PP between species (or populations within species). Expand
Ecological limits to plant phenotypic plasticity.
It is shown that plastic responses to abiotic factors are reduced under situations of conservative resource use in stressful and unpredictable habitats, and that extreme levels in a given abiotic factor can negatively influence Plastic responses to another factor. Expand
The effects of phenotypic plasticity and local adaptation on forecasts of species range shifts under climate change.
It is shown that when population differentiation is accounted for and dispersal is restricted, forecasts of species range shifts under climate change are even more pessimistic than those using the conventional assumption of homogeneously high plasticity across a species' range. Expand

Thermal tolerances of a large number of terrestrial ectotherm, endotherm and plant species worldwide are analysed, and it is shown that tolerance to heat is largely conserved across lineages, while tolerance to cold varies between and within species. Expand
