Active or passive? Specific-leaf-area plasticity responses
Liu et al. conducted a meta-analysis to test the hypothesis that shade-induced increases in specific-leaf-area (SLA) indicate an adaptive plant response to

Phylogenetic insights into the evolution of Saxifragales habitat shifts
Species-level phylogeny and habitat evolution data are applied to the hyper-diverse angiosperm clade Saxifragales to reveal that habitat shifts are very rare. Saxifragales lineages

Boron toxicity tolerance mediated by H2 during rice seed germination
Boron (B) is essential for plant growth, but hazardous when present in excess. Hydrogen gas (H2) possesses antioxidant properties. Wang et al. investigate B-induced biological

Terrestrial predators and nutritional trade-off in Bromeliaceae
Bromeliads occur in many oligotrophic environments, due to the evolution of leaf trichomes, epiphytism, and CAM metabolism. Among bromeliads, Tillandsioideae possess the most derived features related

Shading and litter depth mediate the effects of soil fertility on starflower distribution
Copeland and Harrison test the relative importance of abiotic and biotic variables on distribution of a common herb species, starflower (Trientalis latifolia, Myrsinaceae), in the Klamath-

Germination responses to pre-dispersal light and post-dispersal cues
Should seeds respond to their parents’ environments or their own? Leverett et al. hypothesize that germination would respond more strongly to a post-dispersal vegetative canopy
