Hakea drought resistance determined by climate factors rather than functional traits
Cavitation resistance appears to be genetic, making it useful as a predictor of drought resistance.

Are a few, large seeds or many, small seeds a better strategy for a plant?
For the first time, estimates of comparative seed yield and number for over 800 annuals and their predictor equations have been produced and the ecological importance of these regenerative traits has been illustrated.

Where do halophytes grow? Influence of elevation, flooding, and salinity in a non-tidal saltmarsh
Unpredictability means that the traits needed to survive in seasonally flooded marshes are different to tidally flooded marshes.

Simulating the effects of local adaptation and life history on the ability of plants to track climate shifts
Local adaptation is common but not universal in plants and results from the interplay of gene flow with natural selection. Gene flow can increase local genetic variation and population size, which boost a species’...

Arabidopsis halleri: a model system for studying population differentiation and local adaptation
Whilst studies on Arabidopsis thaliana have generally been highly molecular and/or genetic in nature, most studies using A. halleri have addressed adaptation and variation in adaptive traits in the species’ natural...
Modelling reveals how fire and water shape the life strategies of Pinus halepensis
Is it better to grow fast, or to grow slowly and invest in the future? Structural Equation Modeling reveals that Pinus halepensis cannot decide.

Evolution of mating system, life history, and photosynthetic physiology in Clarkia
In the western United States, Clarkia (Onagraceae) taxa vary in mating system, life history, and photosynthetic physiology. Self-fertilizing taxa bloom earlier in the year and have higher rates of photosynthesis than...

Sex-specific morphology and physiology in Ceratodon purpureus
Separate sexes and biased sex ratios are common in bryophytes, yet little is known about how fine-scale, sex-specific morphological traits are correlated with physiology and population sex-ratios. Slate et al. analysed...
Intra-specific variation in Arabidopsis functional strategies
Considerable intra-specific variation in functional strategies can occur within a single plant species. C-S-R theory was developed to classify functional strategies (competitive, stress tolerant, ruderal) in different...
Whole-plant organisational traits and ecological strategies in sunflowers
While trait-based plant ecology attempts to use small numbers of organ-level traits to predict ecological strategies, there is a major gap between organ-level ecophysiology and plant fitness in an environmental context...
Variation in outcrossing and photosynthetic rates in Clarkia reveals independent evolutionary transitions
Adaptive hypotheses to explain the evolution of self-fertilisation in plants are well-characterised, but alternative evolutionary pathways are underexplored. The mating systems and photosynthetic rates of some sister...
Seed dormancy distribution and ecology
In sea beet, Beta vulgaris ssp. maritima, seed dormancy largely controls germination timing, is highly heritable and varies geographically; climate might select for this trait. Wagmann et al. assess geographical...
Root traits and decomposition rates
Fine-root decomposition is an important determinant of nutrient and carbon cycling in grasslands, but little is known about the factors controlling interspecific root decomposition. By studying 18 Mediterranean...
