Tropical understory communities are highly diverse, and plants in these environments must optimize functional traits to ensure ecological and evolutionary success. Campany et al. survey the ecophysiology of two spore bearing vascular plant groups, Selaginella and ferns, in a lowland Costa Rican tropical forest understory. Selaginella in shade has higher chlorophyll levels and lower light […] More
Evaluation of a generic biomass partitioning model demonstrates accurate temporal patterns of biomass and nitrogen partitioning. More
Earlier this year we reported on how it looked like bladderworts were farming their food, as much as hunting it. A paper submitted before those came out adds to the story, by examining the ‘trophic level’ of bladderwort and butterwort prey. More
Functional–structural plant models (FSPMs) explicitly describe individual plant architecture, making this approach suitable for unravelling plant–plant interactions in complex canopies. Barillot et al. developed a comprehensive FSPM accounting for the interactions between plant architecture, light, soil nitrogen and the metabolism of carbon and nitrogen. The model is evaluated by simulating the functioning of post-anthesis wheat […] More
Predicting the effects of climate change on tree species and communities is critical for understanding the future state of our forested ecosystems. In a recent study published in AoB PLANTS, Rodgers et al. used a fully factorial precipitation by warming experiment in an old-field ecosystem in the northeastern United States to study the climatic sensitivity […] More
The plant that was almost loved to death returns to its former partner. More
You might be surprised that it has any positive effects, but anthropogenic Nitrogen has been boosting the nutrients for sugar maples in Michigan. But these benefits are likely to be lost in the future due to rising CO2 concentrations. More
Plant regrowth in response to defoliation relies on efficient nitrogen use. Roche et al. find that remobilisation of water soluble carbohydrate stores in leaves of perennial ryegrass (Lolium perenne) is coordinated with nitrogen availability to support efficient N assimilation into amino acids in leaf and sheath tissues. Spatiotemporal changes in cytokinin content in response to […] More
Tillering is an important agronomic trait for rice population quality and grain production. In a recent study published in AoB PLANTS, Wang et al. found that nitrogen fertilizer application increased the number of rice tillers, but not every tiller contributed equally to the overall yield. Heterogeneity in tiller yield of rice increased with increasing nitrogen […] More
Partially mycoheterotrophic nutrition is a widespread trophic strategy in green-leaved Orchidaceae species in forest habitats. Owing to the light limitation of their habitats, many forest orchids meet carbon demands though autotrophy, and by tapping into the nutritional reserves provided by mycorrhizal fungi. Schiebold et al. analysed the food webs of 12 taxa in the orchid […] More
Competitive crops are important for sustainable cropping systems. For perennial weeds, below-ground organs, for instance rhizomes for couch grass, constitute the best measure of a crop’s long term suppressive capabilities. Ringselle et al. found that the type of competition (primarily for light or nutrients) utilised by a crop influences both the suppression rate and the […] More
Based on a mechanistic approach, the CN-Wheat model simulates the fluxes of carbon (C) and nitrogen (N) metabolites in wheat plants after anthesis. Barillot et al. show that the CN-Wheat model can be used to predict allocation and dynamics of C and N resources among culm organs in conjunction with observations from field experiments. CN-Wheat […] More
