Background Most tropical and subtropical plants are biotically pollinated, and insects are the
major pollinators. A small but ecologically and economically important group of plants …

Since Darwin, the diversity of flowers has been attributed to selection by pollinators.
Although pollinators commonly act as selective agents on floral traits, determining the extent …

We present an integrative model predicting associations among epiphytism, the tank habit,
entangling seeds, C 3 vs. CAM photosynthesis, avian pollinators, life in fertile, moist …

Molecular phylogenetic studies have become a major area of interest in plant systematics,
and their impacts on historical biogeographic hypotheses are not to be disregarded. In …

Most studies of plant community assembly have focused on how the abiotic aspects of a
habitat (eg soil moisture or mineral composition) or direct interactions among plants in a …

The unparalleled biodiversity found in the American tropics (the Neotropics) has attracted
the attention of naturalists for centuries. Despite major advances in recent years in our …

Abstract Gesneriaceae (ca. 3400 species) is a pantropical plant family with a wide range of
growth form and floral morphology that are associated with repeated adaptations to different …

Much of what we know about speciation comes from detailed studies of well‐known model
systems. Although there have been several important syntheses on speciation, few (if any) …

Abstract The Cape region of South Africa is one of the most remarkable hotspots of
biodiversity with a flora comprising more than 9000 plant species, almost 70% of which are …

It has been proposed frequently, from Darwin's time onwards, that specialized pollination
increases speciation rates and thus the diversity of plant species (ie clade species richness) …
