Mapping functional relationships between multiple ecosystem services (ES) reveals previously unidentified areas of high ES value, which suggests that the spatial focus of planning for optimal ES provisioning may shift when relationships between several ES are considered.
The movement of F-actin filaments, which is regulated by actin-myosin interactions together with a female gamete-specific Rho-GTPase, enables migration of the Arabidopsis sperm cell nucleus towards the female nucleus; which might account for the loss of centrosomes in flowering plants.
Gamete-derived three-amino-acid-loop-extension homeodomain proteins activate zygote development in a strikingly similar manner between basal land plants and green algae, indicating an ancestral role of these transcription factors in green plants.
Research in molecular ecology and evolution is increasingly utilizing the model plant Arabidopsis thaliana, placing a spotlight on its natural history.

Following the last deglaciation in the North Atlantic, DNA evidence shows Betulaceae colonization was consistently delayed compared to Salicaceae, which may serve as an analog for modern global warming.
Aquatic animals cocultured with rice in paddy ecosystems can increase food production, improve nitrogen (N)-use efficiency, and maintain soil fertility by reducing weeds, and promoting recycle and complementary use of N.
