DOI: 10.1002/ajb2.1013
Abstract: PREMISE OF THE STUDY Heterostyly, the reciprocal positioning of stigmas and anthers in different floral morphs, has long been thought to promote intermorph pollination. However, extensive intramorph pollination occurs commonly in heterostylous species, leading to… read more here.

DOI: 10.1002/ajb2.1275
Abstract: PREMISE Evolutionary transitions among floral morphologies, many of which provide evidence for adaptation to novel pollinators, are common. Some trumpet-shaped flowers are among the largest flowers in angiosperms, occurring in different lineages. Our goal was… read more here.

DOI: 10.1002/ajb2.1447
Abstract: PREMISE Water-pollination (hydrophily) is a rare but important pollination mechanism that has allowed angiosperms to colonize marine and aquatic habitats. Hydrophilous plants face unique reproductive challenges, and many have evolved characteristic pollen traits and pollination… read more here.

Pollen competition in hybridizing Cakile species: How does a latecomer win the race?

DOI: 10.1002/ajb2.16035
Abstract: Abstract Premise Hybridization between cross‐compatible species depends on the extent of competition between alternative mates. Even if stigmatic compatibility allows for hybridization, hybridization requires the heterospecific pollen to be competitive. Here, we determined whether conspecific… read more here.

DOI: 10.1002/ajb2.16128
Abstract: PREMISE OF THE STUDY The role of pollinators in evolutionary floral divergence has spurred substantial effort into measuring pollinator-mediated phenotypic selection and its variation in space and time. To estimate pollinator-mediated selection it is necessary… read more here.

DOI: 10.1002/ajb2.16160
Abstract: PREMISE Fire induces flowering in many plant species worldwide, potentially improving reproductive fitness via greater availability of resources, as evident in flowering effort, and improved pollination outcomes, as evident by seed set. Post-fire increases in… read more here.

Beyond P:O ratios: evolutionary consequences of pollinator dependence and pollination efficiency for pollen and ovule production in angiosperms.

DOI: 10.1002/ajb2.16177
Abstract: PREMISE The relative per-flower production of ovules and pollen varies broadly with angiosperm mating systems, with outcrossing types commonly producing more pollen grains per ovule than selfing types. The evolutionary causes of this variation are… read more here.

DOI: 10.1002/ajb2.16181
Abstract: PREMISE OF THE STUDY Linum suffruticosum shows variation in pollinator fit, pollen pick up, and local pollinators that predict pollen deposition rates. The species often co-flowers with other Linum species using the same pollinators. We… read more here.

Asymmetric reproductive interference: The consequences of cross‐pollination on reproductive success in sexual–apomictic populations of Potentilla puberula (Rosaceae)
Sign Up to like & getrecommendations! Published in 2018 at "Ecology and Evolution"
DOI: 10.1002/ece3.3684
Abstract: Abstract Apomixis evolves from a sexual background and usually is linked to polyploidization. Pseudogamous gametophytic apomicts, which require a fertilization to initiate seed development, of various ploidy levels frequently co‐occur with their lower‐ploid sexual ancestors,… read more here.

Abstract: Abstract Wildflower strips (WFS) are increasingly used to counteract the negative consequences of agricultural intensification. To date, it is poorly understood how WFS promote flower visitation and pollination services in nearby insect‐pollinated crops. We therefore… read more here.
