Boreas, EarlyView.Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

As old as the mountains: the radiations of the Ericaceae [PDF]
New Phytologist, 2014 SummaryMountains are often more species‐rich than lowlands. This could be the result of migration from lowlands to mountains, of a greater survival rate in mountains, or of a higher diversification rate in mountains. We investigated this question in the globally distributed family Ericaceae, which includesc.

Boreas, EarlyView.Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Boreas, EarlyView.A long‐term perspective on landscape evolution is critical for understanding past land‐use activity, land cover–climate feedbacks and, notably, for establishing a factual basis for conservation. Fossil pollen analysis provides a means to achieve this. Biases pertaining to pollen productivity, pollination processes and basin size, however, mean there is

Entomologia Experimentalis et Applicata, EarlyView.Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems
Entomologia Experimentalis et Applicata, EarlyView.We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.
