Bumblebees and pollination of endemic Onobrychis pindicola (Fabaceae) in the subalpine habitats of Pirin Mts

open access: yesBiologica Nyssana, 2018
Onobrychis pindicola subsp. urumovii Degen & Dren. is an endemic with restricted distribution on Pirin Mts. and Slavjanka Mts. (Balkan Peninsula, SW Bulgaria).

Do Mimic Hoverflies Spatially Match Their Bumblebee Models? Evidence From a Polymorphic Mimicry System

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Polymorphic Batesian mimics are often expected to track the distributions of their respective model species. We found substantial overlap among color morphs of Volucella bombylans and their putative Bombus models, while habitat suitability for Bombus lapidarius positively predicted the occurrence of all three hoverfly morphs.

Signals of Paleotemperature in the Age Structure and Seasonal Distribution of Pollination Syndromes Across a Temperate Region

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Species with wind & insect pollination syndromes show distinct age structure patterns. Splitting insect pollination into different categories show constrasting age structure. Modern flowering seasons track paleotemperature signatures. ABSTRACT Across the planet, angiosperm diversification has been shaped by palaeoclimates and biotic interactions ...

Boundary‐Only Weak Deflection by Regular Black Holes, Black‐Bounces, Wormholes, and Static Quadrupolar Spacetimes

open access: yesFortschritte der Physik, Volume 74, Issue 8, August 2026.
ABSTRACT We apply the boundary‐only isothermal formulation of finite‐distance weak gravitational deflection to regular black holes, black‐bounces, traversable wormholes, non‐asymptotically flat backgrounds, and static quadrupolar spacetimes. The methodological advance is not a new value for a known bending angle.

Chitosan‐protected dsRNA increases efficacy against Helicoverpa armigera without compromising biosafety for pollinators

open access: yesPest Management Science, Volume 82, Issue 8, Page 7746-7757, August 2026.
Chitosan/tripolyphosphate/double‐stranded RNA (dsRNA) nanoparticles enhance RNA interference efficacy of orally delivered dsRNA against Helicoverpa armigera. Nanoparticles reduce the LC50 and do not cause deleterious effects or toxicity on beneficial insects.

Social information about others' affective states in a human‐altered world

open access: yesJournal of Animal Ecology, Volume 95, Issue 8, Page 1311-1325, August 2026.
Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

Genetic differentiation and adaptive evolution of buff‐tailed bumblebees in Asia

open access: yesInsect Science, Volume 33, Issue 4, Page 1719-1736, August 2026.
This study investigates the genetic differentiation and local adaptation of the buff‐tailed bumblebee (Bombus terrestris) across its European and Asian populations. Using whole‐genome resequencing, we identified distinct genetic differences between populations, with Asian B. terrestris representing a unique genetic resource.
