Smaller plants are the main drag on both seed production and synchrony in their populations.

Explaining seed bank size of an invasive shrub
Bakker et al. find a positive relationship between plant size (V) and seedbank size (S), the SV relationship, using the invasive shrub Ulex europaeus as an example. Bigger plants produce more seeds and ultimately...

What drives germination and seedling survival in an Afrotropical forest?
Hunting in otherwise intact tropical forests removes organisms from some trophic levels, which can change population and community dynamics at other levels. The preferred game species can be dispersers of seeds (e.g...

Geographical variation in damage tolerance: the case of oaks and weevils
The assertion that plants at lower latitudes should be better defended against enemies has a long historical basis but is still controversial. In the current study, Bogdziewicz et al. explore the interaction among holm...
Intra-specific facilitation promotes the recruitment of a desert shrub
In stressful environments, nurse elements, such as shrubs or rocks, facilitate plant recruitment by providing less severe environments for seed germination and seedling survival. As seedlings develop, however, they may...

Shade tolerance, fruiting phenology and Janzen-Connell effects in Amazonian palms
Differences in shade-tolerance and fruiting phenology life history traits may explain variation in the strength of Janzen-Connell effects across whole communities.

Seed dormancy cycling and mortality in Arabidopsis thaliana
The contribution of variation in seed bank dynamics to local adaptation is not well studied. Postma et al. investigated the extent to which genetic and environmental factors affect dormancy cycling and mortality of...
Rainwater in cupulate bracts repels seed herbivores in a bumblebee-pollinated alpine flower
The discovery of new adaptations of organisms to various environments always reminds us how little we know about nature. For example, rainwater surrounding sexual organs has been noted in several flowering plant groups...
Effects of pollination limitation and seed predation on female reproductive success of a deceptive orchid
For many species of conservation significance, multiple factors limit reproduction. In a new study published in AoB PLANTS, Walsh et al. examined the contribution of plant height, number of flowers, number of stems, as...
Seed predator satiation and seedling recruitment
Isoglossa woodii (Acanthaceae) exhibits population-wide synchrony in reproduction and mortality. Tsvuura et al. invoke predator satiation and facilitation of seedling establishment as explanations for masting and...
