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 ...

European Journal of Entomology, 2006 A thioredoxin-like protein (txl) gene was cloned from the bumblebee, Bombus ignitus. The B. ignitus txl (Bitxl) gene spans 1777 bp and consists of three introns and four exons coding for 285 amino acid residues with a conserved active site (CGPC).

Global Change Biology Communications, Volume 1, Issue 3, September 2026.We show that impacts of agriculture on arthropod biodiversity are notably less negative in Europe than in other regions, which we find is driven by a degraded baseline, a selection bias of reference sites, and novel species compositions in agriculture that favour widespread habitat generalists and non‐native species.

Dispersion of Bumblebee Bombus Semenoviellus Skorikov (Hymenoptera, Apidae) in Poland
Journal of Apicultural Science, 2020 The aim of the study is to present all distribution sites of Bombus semenoviellus in Poland reported between 1988 and 2019. The increase of species dispersion was concluded, especially in the central part of the country, as well as the occurrence in the ...

Journal of Applied Entomology, Volume 150, Issue 8, Page 1017-1024, September 2026.ABSTRACT Climate change and environmental disasters can jointly impact species distributions and ecosystem stability, including pollinators and the resources they rely on. We used occurrence and climate data to predict the distribution of Apis mellifera in the Doce River Basin, south‐east Brazil, under baseline and future scenarios (2050).
