Hybridization has long been recognized as a fundamental evolutionary process in plants
but, until recently, our understanding of its phylogenetic distribution and biological …

Abstract With c. 24 700 species (10% of all flowering plants), Asteraceae are one of the
largest and most phenotypically diverse angiosperm families, with considerable economic …

Some of the largest impacts of climate change are expected in the environmentally
heterogeneous and species rich high mountain ecosystems. Among those, the Neotropical …

Evolutionary shifts among radiate, disciform and discoid flowerheads have occurred
repeatedly in a number of major lineages across the Asteraceae phylogeny; such transitions …

The monumental work of Olov Hedberg provided deep insights into the spectacular and
fragmented tropical alpine flora of the African sky islands. Here we review recent molecular …

Identifying the genetic architecture underlying adaptive traits is exceptionally challenging in
natural populations. This is because associations between traits not only mask the targets of …

Hybridisation is well documented in many species, especially plants. Although hybrid
populations might be short-lived and do not evolve into new lineages, hybridisaiton could …

Models of local adaptation to spatially varying selection predict that maximum rates of
evolution are determined by the interaction between increased adaptive potential owing to …

Maritime plants contain dwarf ecotypes that are adapted to exposure to strong winds
transporting salt spray. When variants differentiated from local populations are well‐adapted …

Rapid environmental change is forcing populations into environments where plasticity will
no longer maintain fitness. When populations are exposed to novel environments …
