Rebuilding community ecology from functional traits.
Species abundance distributions: moving beyond single prediction theories to integration within an ecological framework.
Theoretical, empirical and statistical developments in the study of Species abundance distributions are reviewed and it is optimistic that SADs can provide significant insights into basic and applied ecological science.
The return of the variance: intraspecific variability in community ecology.

Assemblage Time Series Reveal Biodiversity Change but Not Systematic Loss
This work analyzes 100 time series from biomes across Earth to ask how diversity within assemblages is changing through time and detects systematic loss of α diversity, but community composition changed systematically through time, in excess of predictions from null models.
Warming experiments underpredict plant phenological responses to climate change
Warming experiments underpredict advances in the timing of flowering and leafing by 8.5-fold and 4.0-fold, respectively, compared with long-term observations, which introduces uncertainty into ecosystem models that are informed solely by experiments and suggest that responses to climate change that are predicted using such models should be re-evaluated.
A test of the unified neutral theory of biodiversity

Whether the zero-sum multinomial distribution fits several empirical data sets better than the lognormal distribution does not, and there is no evidence that the ZSM predicts abundancesbetter than the much more parsimonious null hypothesis.
How do traits vary across ecological scales? A case for trait-based ecology.
The lack of variance at the plot level brings substantial support to the idea that trait-based environmental filtering plays a central role in plant community assembly and supports a shift of focus from species-based to traits-based ecology.
Towards a unification of unified theories of biodiversity.

It is shown that all six unified theories use the same three rules or assertions to describe a stochastic geometry of biodiversity, and these three rules appear sufficient to explain local species abundance distributions, species-area relationships, decay of similarity of distance and possibly other patterns of biodiversity.
