Beetles as floral visitors in the Magnoliaceae: an evolutionary perspective
Arthropod-Plant Interactions, 2021Due to its ancient origin in the Permian and the high proportion of beetle-pollinated taxa within ancestral magnoliid lineages, it has been hypothesized that beetles were among the first floral visitors of the proto-angiosperms on Earth. Thus, beetle-pollinated flowers have become important model systems essential for the study of the origin and ...

Plant Biology, 2017 Abstract The association between plants and flower visitors has been historically proposed as a main factor driving the evolutionary change of both flower and pollinator phenotypes. The considerable diversity in floral morphology within the tribe Antirrhineae has been traditionally related to pollinator types.

Arthropod-Plant Interactions, 2017
Animal pollination is responsible for the majority of the human food supply. Understanding pollination dynamics in agricultural systems is thus essential to help maintain this ecosystem service in the face of human disturbances. Surprisingly, our understanding of plant–pollinator interactions in widely distributed smallholder agricultural systems is ...

Global meta‐network of legume crops and floral visitors reveals abundance of exotic bees
Journal of applied entomology, 2021Legume crops (family Fabaceae, order Fabales) constitute a relevant component of the human food supply. In view of the global decline in crop production, as a result of increasing threats (such as habitat fragmentation and land use change) to pollinators,

Relative pollination effectiveness of floral visitors of Pitcairnia angustifolia (Bromeliaceae)
American Journal of Botany, 2007The effectiveness of flower visitors as pollinators will determine their potential role as selective agents on flower traits. Pitcairnia angustifolia has floral characters that would fit pollination by long‐billed hummingbirds, and they should be the most effective pollinators for this plant.

Identification of Floral Visitors ofIris nelsonii
Southeastern Naturalist, 2012Abstract Floral visitors of the homoploid hybrid species, Iris nelsonii (Abbeville Red Iris), were observed and identified in order to determine whether Abbeville Red Iris flowers are visited by similar floral visitors as its progenitor Iris species. The most common floral visitors to Abbeville Red Iris flowers were Archilochus colubris (Ruby-throated ...

Floral biology and flower visitors on subantarctic Campbell Island
New Zealand Journal of Botany, 2013Abstract Island plants often show reduced floral pigmentation and display size compared with mainland relatives, which is commonly thought to relate to a lack of specialized pollinators. Some species on New Zealand's subantarctic islands have spectacular, highly pigmented inflorescences, yet the depauperate insect fauna provides little apparent ...

Evolutionary Ecology, 2018
Floral visitor assemblages within plant populations are usually composed of different visitors, and the relative abundance of these visitors also varies. Therefore, identifying the relative strength of these floral visitors driving floral evolution within the population is an important step in predicting the evolutionary trajectory of floral traits ...

Mobile stamens enhance pollen dispersal by scaring floral visitors away
2022Summary Animal-pollinated plants have to get pollen to a conspecific stigma while protecting it from getting eaten. We provide experimental evidence that touch-sensitive stamens function in (i) enhancing pollen export and (ii) reducing pollen loss to thieves. Stamens of Berberis and
