Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

open access: yesBoreas, 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]

open access: yesNew 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.

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

open access: yesBoreas, 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 ...

Modern pollen rain of an upland area: implications of pollen dispersal for interpreting palaeoenvironmental records

open access: yesBoreas, 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

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia 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

open access: yesEntomologia 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.
