Caracterización y variación espacio-temporal del néctar en anarthrophyllum desideratum (Fabaceae): Influencia del clima y los polinizadores

Boletín de la Sociedad Argentina de Botánica, 2012
En este trabajo se caracterizó el volumen, la concentración y la composición de azúcares del néctar floral en Anarthrophyllum desideratum (DC) Benth., un arbusto endémico de la estepa Patagónica polinizado por aves Passeriformes, y se evaluó su variación

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

Am 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 ...

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

Insect Conservation and Diversity, EarlyView.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Sheep and cattle grazing regimes differentially affect ground beetle and ant communities in Mediterranean cork oak woodlands

Insect Conservation and Diversity, EarlyView.
Sheep and cattle grazing significantly shape ant and ground beetle species composition in Mediterranean cork oak woodlands, promoting higher diversity by increasing habitat heterogeneity. Ground beetles and ants reflect changes in grazing regimes, with sheep‐grazed areas showing the highest diversity, highlighting their utility in ecosystem monitoring.

Against the odds: Nesting specialization and foraging ecology provide insights into climate change responses in a mountain bee

Insect Conservation and Diversity, EarlyView.
A unique high‐elevation Exoneura bee defies typical elevation‐driven declines in bee activity, nesting exclusively in dead branches of snow gums near the alpine tree line. Nesting and foraging are tightly linked to snow gum presence, with most activity occurring within 30 m of these trees. Biophysical modelling indicates the bee's thermally constrained

Non‐crop habitats and cover crops as potential ecological corridors and stepping stones for autumnal migrating hoverflies

Insect Conservation and Diversity, EarlyView.
Mass migration of hoverflies was observed near Prague city in a highly agricultural landscape, representing only the second record of hoverfly migration in the Czech Republic. This rare observation was likely driven by the need to rest, shelter and replenish energy, although most flowers had already finished blooming.

Seasonal effects of land cover and intensity of farming practices on α and β diversity of grassland arthropod communities

Insect Conservation and Diversity, EarlyView.
Land cover heterogeneity drives grassland arthropod diversity in spring, while local management intensity becomes the primary driver in autumn, revealing strong seasonal shifts in environmental influences. Landscape‐scale farming intensity significantly shapes arthropod community composition through balanced variation, demonstrating its role as an ...

Canadian boreal restored mining sites sustain diverse pollinator communities, including species of conservation concern

Insect Conservation and Diversity, EarlyView.
Revegetated mine tailing storage facilities support pollinator abundance, diversity, richness and evenness comparable to recently logged boreal forest sites. Agronomic and spontaneous revegetation strategies host similar pollinator and Bombus community structures, indicating multiple rehabilitation approaches can effectively restore pollinator habitat.
