Bee pollination increases yield quantity and quality of cash crops in Burkina Faso, West Africa

Scientific Reports, 2017
Mutualistic biotic interactions as among flowering plants and their animal pollinators are a key component of biodiversity. Pollination, especially by insects, is a key element in ecosystem functioning, and hence constitutes an ecosystem service of ...

Origin of subgenomes in the circumboreal, allopolyploid, carnivorous plant Drosera anglica

American Journal of Botany, EarlyView.
Abstract Premise The parentage of the widespread allopolyploid Drosera anglica, a member of the carnivorous sundew genus, remains uncertain despite over 100 years of morphological, cytological, and, more recently, molecular study. Methods Using transcriptomic and genomic data from 12 species of Drosera sect. Drosera, including four D.

Studies on cross compatibility in Jasminum spp.

The Indian Journal of Agricultural Sciences, 2019
The present investigation was carried out to study the compatibility among six Jasminum species during 2016–17. Among open, self and artificial cross pollination, the open pollination resulted in maximum degree of fruit and seed set proving the open ...

Spring ephemeral Erythronium umbilicatum may not be vulnerable to phenological mismatch with overstory trees

American Journal of Botany, EarlyView.
Abstract Premise The defining life history strategy of spring ephemeral wildflowers is their avoidance of shading by trees during the brief, high‐light period before canopy leaf out. Studies suggest that spring ephemerals will experience increased light competition because canopy leaf out is more sensitive to warming than is the phenology of spring ...

Ethnoecology of pollination and pollinators

Revue d'ethnoécologie, 2015
This paper brings together three case studies on the interrelationships amongst people, pollination processes and pollinators (notably honeybees). In the palm groves of Saharan oases, the milieu and varieties of palm trees are created by horticulturalists, who fulfil themselves the role of pollinators.

The role of pollinator attracting scent in the sexually deceptive orchids Ophrys chestermanii, O. normanii and O. tenthredinifera [PDF]

, 2008
Sexual deception of male bees is one of the most remarkable mechanisms of pollination (Ackermann 1986, Proctor & al. 1996). Flowers of the orchid genus Ophrys mimic females of their pollinator species, usually bees and wasps, to attract males, which try ...

Drivers of insect herbivory resistance and tolerance to plant damage in the Brachypodium distachyon species complex

American Journal of Botany, EarlyView.
Abstract Premise Insect herbivory is a major biotic factor shaping plant populations and driving the evolution of defensive traits. Polyploidy (whole‐genome duplication) often induces substantial phenotypic and genotypic changes that may affect species interactions, including herbivory.
