DOI: 10.1002/ajb2.1158
Abstract: PREMISE OF THE STUDY Nursery pollination systems can range from obligate to facultative. In a system where generalists provide substantial pollination service, an important question is whether the cost of seed predation outweighs the benefit… 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/ajb2.16144
Abstract: The movement of pollen grains from anthers to stigmas, often by insect pollinator vectors, is essential for plant reproduction. However, pollen is also a unique vehicle for viral spread. Pollen-associated plant viruses reside on the… read more here.

Abstract: PREMISE Animal-pollinated plants face a high risk of pollen loss during its transfer. To limit the negative effect of pollen losses by pollen consumption and heterospecific transfer, plant species may adjust and stratify their pollen… 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.

Plasticity in floral longevity and sex-phase duration of Lobelia siphilitica in response to simulated pollinator declines.

DOI: 10.1002/ajb2.1837
Abstract: PREMISE Pollinator declines can reduce the quantity and quality of pollination services, resulting in less pollen deposited on flowers and lower seed production by plants. In response to these reductions, plant species that cannot autonomously… read more here.

Adaptation to lower latitudes and lower elevations precedes the evolution of hummingbird pollination in western North American Penstemon.

DOI: 10.1002/ajb2.1857
Abstract: PREMISE A switch in pollinator can occur when a plant lineage enters a new habitat where the ancestral pollinator is less common and a novel pollinator is more common. Since pollinator communities vary according to… read more here.

Pollinator parasites and the evolution of floral traits
Sign Up to like & getrecommendations! Published in 2019 at "Ecology and Evolution"
DOI: 10.1002/ece3.4989
Abstract: Abstract The main selective force driving floral evolution and diversity is plant–pollinator interactions. Pollinators use floral signals and indirect cues to assess flower reward, and the ensuing flower choice has major implications for plant fitness.… read more here.

DOI: 10.1002/ece3.8619
Abstract: Abstract Understanding how urbanization alters functional interactions among pollinators and plants is critically important given increasing anthropogenic land use and declines in pollinator populations. Pollinators often exhibit short‐term specialization and visit plants of the same… read more here.

DOI: 10.1002/ece3.8847
Abstract: Abstract Pollinator behavior is an important contributor to plants speciation, yet how variation in pollinator behavior causes variation in reproductive isolation (RI) is largely uncharacterized. Here I present a model that predicts how two aspects… read more here.
