Pollinator-mediated interactions between plant species may affect the composition of angiosperm communities. Floral colour signals should play a role in these interactions, but the role will arise from the visual...

Functional traits of vascular plants colonizing alpine cushions
Global warming threatens species living in the highest and coldest areas. Alpine cushion plants are potentially endangered by stronger species expanding from lower elevations. This can be inferred from their ecological...
Pollination quantity and purity
If you share a pollinator with another plant species in your location, is it a good idea to flower at the same time? You can only use pollen from another plant in the same species. If a bee arrives loaded with another...

Positive and negative interactions on a dioecious grass species performance
Dioecious plants are of particular concern in view of global environmental changes because reproductive females are more sensitive to abiotic stresses, thus compromising population viability. Positive interactions with...
Mating system, ploidy and competition in Capsella species
Capsella is a model genus for studying the transition from outcrossing to selfing, with or without change in ploidy levels. The genomic consequences and changes in reproductive traits (selfing syndrome) associated with...

Modelling the interaction between light competition and herbivore feeding patterns
Plants usually compete with neighbouring plants for resources such as light as well as defend themselves against herbivorous insects. This requires investment of limiting resources, resulting in optimal resource...
A generic individual-based model (IBM) tool to disentangle plant interactions in forage legumes
Louarn and Faverjon develop a generic model to account for the growth and development of herbaceous legume species with contrasting above- and below-ground architectures. The individual-based model (IBM) integrates...
Subtle variation in shade avoidance responses has profound consequences for plant competitiveness
There is limited knowledge on how variation in plastic responses plays a role in determining plant competitiveness. To address this issue, Bongers et al. combine experimentations and simulation modelling to test...
Native species respond differently to nitrogen addition and disturbance
Nitrogen deposition and fire regime suppression are key drivers of vegetation change in urbanising grasslands. In the natural grasslands that surround Melbourne, Australia, some native species have become rarer...
Linking invasive–native plant competition to foraging and nutrient conditions
The effects of the competition between invasive and native plants have rarely been linked with root foraging behaviour. Chen et al. performed a competition experiment with two invasive-native species pairs (Bidens...
Contrasting soil-texture niches, competitive abilities, and coexistence
When closely related plant species occur in the same region, their distributions at small spatial scales are expected to depend on whether they have evolved different tolerances to variation in the environment. Whether...

The benefits of sleeping in
The early bird catches the worm, but does the frost catch the early plant? A new article in AmJBot says there are advantages for a plant to germinate late.

Stress or Strain Gradient Hypothesis?
The Stress Gradient Hypothesis (SGH) proposes that competition prevails in undisturbed and productive environments, and shifts to facilitation in disturbed or stressful environments. Yet the environmental condition...
Light competition suppresses couch grass more efficiently than nutrient competition
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...
