Roadside pollinator populations and the negative impact of intensive roadside vegetation maintenance

Insect Conservation and Diversity, EarlyView.
Less intensively managed roadsides had higher numbers of flower flies and bees; bee diversity was also higher in those roadsides. Community composition was similar across both management types, indicating that roadsides support a fairly homogeneous pollinator community, regardless of management.

Unequal pollinator benefits from partial mowing regimes in a field experiment

Insect Conservation and Diversity, EarlyView.
Pollinators aggregate in unmown refuges in partially mown vegetation in the first days after mowing. Up to four weeks after mowing, this initial aggregation is followed by a subsequent decline in abundance not observed in unmown locations. This decline is paired with a species richness decrease, revealing that partial mowing filters pollinator ...

Floral Trait Influence on the Foraging Decisions of a Fly Pollinator

Journal of Applied Entomology, EarlyView.
ABSTRACT Flies foraging for floral resources provide important ecosystem services through the pollination of myriad angiosperms, including many crop species. However, the specific floral cues used by fly pollinators to locate and discriminate among floral rewards and the preferences they may have for specific cues remain poorly understood.

Linking genomic variation to floral trait adaptation across species boundaries

New Phytologist, EarlyView.
Examples of floral trait divergences between sister species adapted to different pollination modes. Summary Flowers are highly diverse in shape, scent, and colour and may differ strikingly even among closely related species. Floral traits experience correlational selection favouring trait combinations that maximise plant reproduction, leading to ...

Assessment of Pollen Production, Pollen Viability, Autofertility and Paternal Success in Faba Bean (Vicia faba L.) for Better Exploitation of Grain Yield Heterosis

Plant Breeding, EarlyView.
ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

Bee Pollen Flavonoids as a Therapeutic Agent in Allergic and Immunological Disorders

Iranian Journal of Allergy, Asthma and Immunology, 2017
Bee pollen grains, as the male reproductive part of seed-bearing plants contain considerable concentrations of various phytochemicals and nutrients. Since antiquity, people throughout the world used pollens to cure colds, flu, ulcers, premature aging ...

Comparative analysis of immune responses in ovipositing and non‐ovipositing females of European earwig Analyse comparative de la réponse immunitaire avant et après la ponte chez le forficule européen

Physiological Entomology, EarlyView.
Oviposition and care decrease the total haemocyte concentration. Oviposition and care affect haemocyte type proportions. Serratia marcescens challenge does not affect the immune cell parameters. Abstract Reproduction and immunity are essential biological processes that compete for resources and energy.

Floral adaptation and modular trait evolution associated with a shift from bee to hummingbird pollination

Plant Biology, EarlyView.
By comparing floral trait variation, integration and modularity in two sister species of Neotropical Costus with a pollination shift, we show that, despite pollination syndrome divergence, both species exhibit low floral variation and functional modularity, consistent with pollinator‐driven selection on traits mediating pollen transfer efficiency and ...

Mixed‐vertebrate pollination traits and pollinators of Haageocereus acranthus (Cactaceae) in a lomas desert ecosystem of coastal Peru

Plant Biology, EarlyView.
In a lomas desert ecosystem of coastal Peru, the columnar cactus Haageocereus acranthus shows traits and interactions consistent with a mixed‐vertebrate pollination system (hummingbirds and bats), with no detectable differences between flower colour morphotypes in either traits or interactions.

A dual pollination strategy combining perfume attraction and food deception in Galeandra blanchetii E.S. Rand (Orchidaceae)

Plant Biology, EarlyView.
Galeandra blanchetii exhibits a dual‐attraction strategy: male euglossine bees are lured by floral scents as a resource, while both sexes are deceived by non‐existent nectar. Pollination only occurs when bees enter the spur to search for nectar, highlighting an evolutionary transition towards the perfume flower syndrome in Catasetinae.
