Ants on flowers: Protective ants impose a low but variable cost to pollination, moderated by location of extrafloral nectaries and type of flower visitor

open access: yesJournal of Ecology, Volume 113, Issue 8, Page 2187-2198, August 2025.
Individuals who engage in multiple mutualisms often have to pay indirect costs because of the interference of one mutualism on another. We found that protective ants had a low but variable impact on pollination, especially on the flower visitation by bees and when EFNs are close to inflorescences.

On the success of a swindle: pollination by deception in orchids [PDF]

open access: yes, 2018
A standing enigma in pollination ecology is the evolution of pollinator attraction without offering reward in about one third of all orchid species. Here I review concepts of pollination by deception, and in particular recent findings in the pollination ...

Rocksitter Flies (Lauxaniidae: Cestrotus) are Key‐Pollinators of Ceropegia pulchellior—A Threatened and Localised South African Endemic With Foetid‐Scented Flowers

open access: yesJournal of Applied Entomology, Volume 149, Issue 6, Page 888-900, July 2025.
ABSTRACT Short‐tongued saprophilous flies are a diverse but under‐appreciated group of pollinators, which are particularly important for flowers in the subtribe Stapeliinae (Apocynaceae‐Asclepiadoideae‐Ceropegieae). This clade of plants is characterised by repeated shifts between tubular kettle‐trap and open non‐trap flowers and chemical mimicry (of ...

Butterflies, bumblebees and hoverflies are equally effective pollinators of Knautia arvensis (Caprifoliaceae), a generalist plant species with compound inflorescences

open access: yesJournal of Applied Entomology, Volume 149, Issue 5, Page 685-696, June 2025.
Abstract Plant‐pollinator interactions exist along a continuum from complete specialisation to highly generalised, that may vary in time and space. A long‐held assumption is that large bees are usually the most effective pollinators of generalist plants.

Time of flowering and fertilisation of quince varieties

open access: yesInternational Journal of Horticultural Science, 1999
Literature dealing with flowering and fertilisation of quince is scarce. Most controversial and scanty are informations on observations of self- and cross-pollination.

The spatial distribution of a hummingbird‐pollinated plant is not strongly influenced by hummingbird abundance

open access: yesAmerican Journal of Botany, Volume 112, Issue 5, May 2025.
Abstract Premise Many angiosperms have evolved specialized systems that promote pollination by specific taxa. Therefore, plant distributions may be limited by the local abundance of their specialist pollinators. In eastern North America, Lobelia cardinalis is thought to be pollinated solely by Archilochus colubris, the only hummingbird species found in
