In Central Argentina grows a tree which can produce flowers with different sexual characteristics? Why? Is there an advantage to changing your sex life if you're a plant?
The genus Boechera (Brassicaceae) is comprised of both sexual and apomictic species, permitting comparative analyses of meiotic disturbances and parthenogenesis. Hybridization, polyploidy and environmental adaptation...
In moss-dominated regions of the Western Antarctic Peninsula, dramatic climate features have profoundly impacted moss biology and terrestrial ecology. In a study focused on the effects of six-years of passive warming on...
Roughly half of the species of bryophytes have separate sexes (dioecious) and half are hermaphroditic (monoecious). This variation has major consequences for the ecology and evolution of the different species. In some...
A revelation concerning amber-encased plant material suggests current sexual reproduction in angiosperms may have changed little in over 100 million years.
Mechanisms enabling the maintenance of sexual and apomictic modes of seed formation in sympatry are poorly understood. Dobeš et al. study populations of Potentilla puberula representing various combinations of five...
Studies have suggested that plant sexual reproduction is particularly vulnerable to climate change, and a number of ecologically and evolutionarily relevant genes have recently been identified. Shimizu et al. consider...
A key factor of pollen-tube attraction to an ovule is that it is species-specific, and recently a family of secreted proteins with attractant properties has been discovered in Torenia fournieri. Kanaoka et al. study...
`Apomixis is not prevalent in a high-alpine ecosystem Apomixis (agamospermy) is expected to provide selective advantages in high alpine environments, where conditions tend to be unfavourable for sexual reproduction of...
