The extent to which propagule pressure limits the establishment of local polyploid populations remains to be determined, because we know so little.

Individual variation in plant dispersal and fecundity increases rates of spatial spread
The highest increases in spread rates occur when variation in dispersal positively co-varies with fecundity.

Simulating the effects of local adaptation and life history on the ability of plants to track climate shifts
Local adaptation is common but not universal in plants and results from the interplay of gene flow with natural selection. Gene flow can increase local genetic variation and population size, which boost a species’...
Fruit heteromorphism and naturalization success in Asteraceae
Finding the factors that explain invasion success of species is a major objective in ecology. The combination of extensive data on fruit heteromorphism in Asteraceae and the largest global plant-naturalization database...

Low-intensity logging and hunting have long-term effects on seed dispersal but not fecundity in Afrotropical forests
Hunting and logging can alter ecological communities, but their long-term effects are seldom studied in Afrotropical forests. Tropical trees respond to environmental disturbance on timescales that usually surpass the...
Molecular phylogenetics and historical biogeography of the tribe Lilieae
Revealing the role played by the Qinghai-Tibet Plateau (QTP) for organismal diversification and biogeography of plants in the Northern Hemisphere, Huang et al. assess phylogenetic relationships and divergence time, and...
The impact of asexual and sexual reproduction on spatial genetic structure in Marchantia
Sexual reproduction requires close proximity of mates, but ensures genetic variation in the local population. Although independent of cross-pollination, asexual reproduction can however, reduce genetic variation in the...
Limited seed and pollen gene dispersal in Taxus baccata
Dispersal is crucial due to its direct impact on dynamics of a species’ distribution as well as having a role in shaping adaptive potential through gene flow. In plants forming scarce and small populations, knowledge...
Population genetics of a rare Grevillea
For conservation of rare riparian species, avoiding an impact to hydrodynamic processes, such as water tables and flooding dynamics, may be just as critical as avoiding direct impacts on the number of plants.

Island fragmentation and colonisation drove diversification of Aegean Nigella
Island organisms are generally understood to diverge through geographical (allopatric) speciation. This paradigm, however, might be too simplistic for continental islands that were connected with each other and/or the...

Diversification of an underutilised crop genus in Borneo
Recent work points to Borneo as an evolutionary and biodiversity hotspot. The genus Artocarpus (Moraceae) has many Borneo endemics, and more than a dozen underutilised crops, including breadfruit. Williams et al...
SPECIAL ISSUE: Island Plant Biology—Celebrating Carlquist’s Legacy
AoB PLANTS is pleased to announce the publication of a Special Issue titled Island Plant Biology—Celebrating Carlquist’s Legacy, edited by Anna Traveset (Mediterranean Institute for Advanced Studies), Donald Drake...
Genetic analysis of spatial overlap by invasive vines
Kartzinel et al. use genetic markers to determine the extent and overlap of genetically unique kudzu vines (Pueraria montana var. lobata) in multiple patches over 2 years, and find that, contrary to expectations...
More news on wandering plants
Natch Greyes’ Carnivorous Plants compares an earlier AoB article on a pygmy drosera with other cases of plants turning up in unexpected places.
