Breeding systems in Tolpis (Asteraceae) in the Macaronesian islands: the Azores...
Crawford, Daniel J.; Anderson, Gregory J.; Silva, Lurdes Borges; Sequeira, Miguel Menezes de; Moura, Mónica; Santos-Guerra, Arnoldo; Kelly, John K.Plants on oceanic islands often originate from self-compatible (SC) colonizers capable of seed set by self fertilization. This fact is supported by empirical studies, and is rooted in the hypothesis that one (or few) individuals could find a sexual population, whereas two or more would be required if the colonizers were self-incompatible (SI). However, a SC colonizer would have lower heterozygosity than SI colo...
Multiplexed-shotgun-genotyping data resolve phylogeny within a very recently de...
Mort, Mark E.; Crawford, Daniel J.; Kelly, John K.; Santos-Guerra, Arnoldo; Sequeira, Miguel Menezes de; Moura, Mónica; Caujapé-Castells, JuliPremise of the study: Endemic plants on oceanic islands have long served as model systems for studying patterns and processes of evolution. However, phylogenetic studies of island plants frequently illustrate a decoupling of molecular divergence and ecological/morphological diversity, resulting in phylogenies lacking the resolution required to interpret patterns of evolution in a phylogenetic context. The curre...
