Integrative approaches to understanding angiosperm origins and diversity
The rise of angiosperms should be studied as part of the global increase in biodiversity.
Fire-timing in relation to reproduction and mast-seeding cycles
In experimental studies, rainfall-stimulated Triodia pungens masting precipitated a large but transitory spike in soil seedbank size and burning populations 6 months after this event triggered mass recruitment.
Endosperm development and hybrid seed failure in wild tomatoes
The overall results suggest that near-complete hybrid seed failure can evolve fairly rapidly and without apparent divergence in reproductive phenology/biology.
Shaping the cline of floral calyx lobe length in Asarum
Divergent selection may have driven the calyx lobe length variation in series Sakawanum taxa, although the underlying mechanism is still not clear.
Carbohydrate storage and leaf biomass scaling in meadow plants
These findings imply that storage in herbs is probably governed by factors other than just the disturbance regime applied once in a growing season.
Hypericum hybrids trapped in their polyploid gene pool
The underlying genetic causes of the switch to apomixes are not yet fully understood, but in Hypericum there is good evidence for the existence of ‘apomictic factors’.
Biogeographic history and climatic niche evolution of Japanese endemic primroses
Climatic changes and historical orogenies during the Quaternary might have played a significant role in determining the speciation and diversification patterns of primroses in Japan.
Nitrogen to phosphorus ratio as a threshold for nutrient limitation in plants (Meta-analysis)
These findings highlight that canonical N:P thresholds have the potential to introduce a large uncertainty when used to detect plant nutrient limitations, suggesting that the error risks should be cautioned in future studies.
Phylogenetic and functional signals in ovular secretions of gymnosperms
This study reinforces the antiquity of insect–plant pollination mutualisms in Gnetophyta, which have a fossil record beginning in the Triassic.
