Nocturnal Lepidopterans as Essential Pollinators of Aspidosperma pyrifolium (Apocynaceae), a Keystone Tree in the Caatinga Dry Forest

Journal of Applied Entomology, Volume 150, Issue 3, Page 351-363, April 2026.
ABSTRACT Pollination is a key ecosystem service, yet most studies focus on diurnal interactions, often overlooking nocturnal pollinators such as hawkmoths and settling moths. In arid environments, nocturnal pollination plays a crucial role in maintaining native plant species of high biocultural value, as seen in the Caatinga dry forest.

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

American Journal of Botany, Volume 113, Issue 2, February 2026.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Self-fertility studies of some sweet cherry (Prunus avium L.) cultivars and selections

International Journal of Horticultural Science, 2004
Fruit set of two sweet cherry cultivars (Alex' and 'Stella' ) and four Hungarian selections have been studied over two years following open pollination, unassisted self-pollination (autogamy) and artificial self-pollination (geitonogamy).

Unusual patterns of hybridization involving two alpine Salvia species: Absence of both F1 and backcrossed hybrids

Frontiers in Plant Science, 2022
Natural hybridization plays an important role in speciation; however, we still know little about the mechanisms underlying the early stages of hybrid speciation. Hybrid zones are commonly dominated by F1s, or backcrosses, which impedes further speciation.

Functional Significance of Labellum Pattern Variation in a Sexually Deceptive Orchid (Ophrys heldreichii): Evidence of Individual Signature Learning Effects. [PDF]

PLoS ONE, 2015
Mimicking female insects to attract male pollinators is an important strategy in sexually deceptive orchids of the genus Ophrys, and some species possess flowers with conspicuous labellum patterns.

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

Biological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Data from: Consequences of multiple inflorescences and clonality for pollinator behavior and plant mating

, 2014
Angiosperms engage in distributed reproduction, producing sex organs in multiple flowers on one or more inflorescences, including on different physical individuals of clonal plants.

Breeding system of the Iberian endemic shrub Colutea hispanica (Leguminosae)

Anales del Jardín Botánico de Madrid, 2009
Plant breeding systems have been viewed as mechanisms to promote outcrossing in order to increase genetic variability and prevent inbreeding depression.

Floral Color Change Mediated by Pollen Input–Output and Its Manipulation of Pollinator Foraging Behavior in Heterostylous Plant Arnebia guttata (Boraginaceae)

Ecology and Evolution, Volume 15, Issue 12, December 2025.
The inducement, functions of flower color change (FCC) and its ecological effects have been studied by controlling pollination, accurate statistics of pollen transfer and visiting behavior in a typical distylous species. The results showed that limiting pollen input–output can delay fading time of spots, adding fake spots to old flowers can improve ...
