Mineral nutrient stoichiometry of Hedera seeds
Analysis of variability in mineral allocation to seeds has rarely been considered in relation to allometric patterns and deviations from the allometric trajectory. Obeso examines the

Co-adaptation of seed dormancy and flowering time
Time from seed dispersal to germination and time from germination to flowering are two key life history traits that determine fitness and coexistence of weeds in

Thermotolerance in pondweeds
Molecular-based studies of thermotolerance have rarely been performed on wild plants, although this trait can be critical for summer survival. Amano et al. use a

Seed quality at tree species’ altitudinal limits
The low-temperature range limit of tree species may be determined by their ability to produce and disperse viable seeds, with processes such as flowering, pollen

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

Model of myxospermous seed-mucilage expansion
Myxospermy, the ability of a seed to produce mucilage upon hydration, is reported to provide important functional advantages to various aspects of seed ecology. Using data

PHAN and compound leaf morphology
For both simple and compound leaves, a MYB domain transcription factor PHANTASTICA (PHAN) plays an important role in establishing the adaxial domain in the leaf. Zoulias

New taxonomy of Brachypodium distachyon
The model grass species Brachypodium distachyon has three cytotypes that are currently regarded as part of a single species. Catalán et al. combine analysis of phenotypic

Passerine pollination in a winter-flowering tree
Birds can be alternative pollinators for winter-flowering plants outside the tropics where low temperatures limit insect activity. Feng et al. observe pollinator visitation to loquat

Ontogeny constrains sprouting in Quercus
Evidence suggest that suppressed bud burst and thus epicormic shoot emergence (sprouting) are controlled by water–carbohydrate supplies to entire trees and buds. Morisset et al.

Progenitor–derivative speciation in Pozoa
Progenitor–derivative speciation occurs when an isolated peripheral population diverges from the ancestral condition and forms a derivative species. López et al. find evidence of this
