Animal pollinators mediate gene flow among plant populations, but in contrast to well‐studied topographic and (Pleistocene) environmental isolating barriers, their impact on population genetic differentiation remains largely unexplored. Comparatively investigating how these multifarious factors drive microevolutionary histories is, however, crucial...

Heteranthery, the presence of distinct stamen types within a flower, is commonly explained as functional adaptation to alleviate the ‘pollen dilemma’, defined as the dual and conflicting function of pollen as pollinator food resource and male reproductive agent. A single primary hypothesis, ‘division of labour’, has been central in studies on heter...
Evolutionary shifts from bee to vertebrate pollination are common in tropical mountains. Reduction in bee pollination efficiency under adverse montane weather conditions was proposed to drive these shifts. Although pollinator shifts are central for the evolution and diversification of angiosperms, we lack experimental evidence of the ecological pro...

Angiosperm flowers have diversified in adaptation to pollinators, but are also shaped by developmental and genetic histories. The relative importance of these factors in structuring floral diversity remains unknown. We assess the effects of development, function and evolutionary history by testing competing hypotheses on floral modularity and shape...

Floral adaptation to a single most effective functional pollinator group leads to specialized pollination syndromes. However, adaptations allowing for pollination by two functional groups (bimodal pollination systems) remain a rarely investigated conundrum. We tested whether floral scent and nectar traits of species visited by two functional pollin...

The tremendous diversity of angiosperm flowers has most likely evolved primarily in connection with their manifold pollinators. A particularly interesting topic located at the interface of pollination ecology and floral evolution is the occurrence of so-called pollinator shifts, i.e., the shift from one functional group of pollinators to another (e.g., from bees to birds). This project focuses on a group of Central- and South American plants (the tribe Merianieae) belonging to the melastome family (Melastomataceae). The Merianieae include bee-, bat-, hummingbird- as well as passerine pollinated species. Using high resolution x-ray computed tomography combined with geometric morphometrics, we aim at analyzing in detail the differences in floral traits associated with different functional groups of pollinators. In addition, using a population genetic approach, we will assess gene flow and pollination efficiency in the different pollination systems.
