Pollination by long-proboscid horseflies and its implications for reproductive isolation among coflowering Satyrium orchids in South Africa. [PDF]

open access: yesAm J Bot
Abstract Premise Floral adaptations to pollinators can drive lineage diversification and promote coexistence of species. We investigated the reproductive biology of Satyrium longicolle, a South African orchid that we hypothesized to belong to a long‐proboscid horsefly pollination guild and examined overlap of pollinators and floral traits among ...

The dual crisis: Climate change simultaneously drives pollinator decline and Pest outbreaks

open access: yesAgricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Plant Reproductive Success Mediated by Nectar Offered to Pollinators and Defensive Ants in Terrestrial Bromeliaceae

open access: yesPlants
Most plants produce floral nectar to attract pollinators that impact pollination and seed production; some of them also secrete extrafloral nectar harvested by insects that may influence the plant reproductive success.

Frequency and Severity of Allergic Reactions to Non‐Mandatory Labelled Allergenic Foods—Data From Two Large European Cohorts

open access: yesAllergy, EarlyView.
In two large European cohorts, 589 reactions to non‐mandatory labelled plant‐based foods were identified with sunflower seed, pine nut, pea and lentil as the most frequent triggers. Reaction severity was not different between mandatory and non‐mandatory labelled allergenic foods. Their frequency and rising trends (e.g., fenugreek, pumpkin seed) support

Anatomy and Histology of the Midgut of Atopozelus opsimus (Heteroptera: Reduviidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Atopozelus opsimus Elkins, 1954 (Heteroptera: Reduviidae) preys on forest and agricultural pests but also feeds on extrafloral nectar; however, its alimentary canal is poorly understood. The aim was to describe the anatomy and histology of the A. opsimus midgut. The alimentary canal of female and male A.

Metabolic and transcriptomic analyses of nectaries reveal differences in the mechanism of nectar production between monocots (Ananas comosus) and dicots (Nicotiana tabacum)

open access: yesBMC Plant Biology
Background Nectar is offered by numerous flowering plants to attract pollinators. To date, the production and secretion of nectar have been analyzed mainly in eudicots, particularly rosids such as Arabidopsis.

Taxonomic and functional diversity of urban bees of the world

open access: yesConservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

From research to conservation: Site selection for habitat restoration of a narrowly distributed and critically endangered butterfly

open access: yesConservation Science and Practice, EarlyView.
This study focuses on the conservation of a rare butterfly in northwestern Italy threatened by woody encroachment. Using field data, topography, and remote sensing, we modelled habitat suitability and connectivity. A 0.6‐ha site was selected for restoration, illustrating how predictive models can guide targeted conservation actions.

Plant Domestication Affects the Oviposition Behavior and Performance of Ganaspis kimorum, a Parasitoid of Drosophila suzukii

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
In this study, we investigated the effects of blueberry domestication on the oviposition behavior and performance of Ganaspis kimorum, a parasitoid of Drosophila suzukii. Domestication of blueberries reduced the oviposition‐searching behavior of the parasitoid but enhanced parasitoid performance, including offspring performance. Additionally, blueberry

Impact of Host and Food Availability on Life‐History Traits in Six Egg Parasitoid Species of the Genus Trichogramma

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...
