Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

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

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.

Comparative phylogenies and host specialization in the alder ectomycorrhizal fungi Alnicola, Alpova and Lactarius (Basidiomycota) in Europe

BMC Evolutionary Biology, 2011
Background Mycorrhizal fungi form intimate associations with their host plants that constitute their carbon resource and habitat. Alnus spp. (Betulaceae) are known to host an exceptional species-poor and specialized ectomycorrhizal (ECM) fungal community

Holocene shoreline displacement and the impact of the Storegga tsunami on Hinnøya, northern Norway

Boreas, EarlyView.
The Holocene relative sea‐level (RSL) history of Norway's largest island, Hinnøya, has been investigated in detail, using sediment records from 25 isolation basins. The sediments were analysed for macrofossil and phytoplankton content, which served as the basis for identifying marine–lacustrine transitions, that is isolation contacts. Terrestrial plant

Triterpenoids and Sterols from the Stem of Burk

Natural Product Communications, 2006
The chemical constituents of the stem of Alnus formosana Burk. were investigated and sixteen known compounds, composed of eleven triterpenoids and five sterols, were isolated and characterized from the n-hexane- and chloroform-soluble fractions of the ...

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

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 ...

Prioritizing site groups for intrinsic biodiversity assets using complementarity and not just rarity

Conservation Science and Practice, EarlyView.
Conservation practitioners rightfully focus on at‐risk species when valuing biodiversity assets and prioritizing spatial units. We compared and combined numbers of at‐risk species with four other community metrics using surveys of vascular plants at wetlands in a preserve network in Illinois, USA.

Comparison of habitats and range overlap of Alnus crispa and Alnus rugosa.

, 1993
The purpose of this paper was to compare Alnus rugosa (A. incana) and Alnus crispa (A. viridis). These Alnus species are similar in successional pattern and they overlap in habitat range.

Distinct Patterns of Symbiosis-Related Gene Expression in Actinorhizal Nodules from Different Plant Families

Molecular Plant-Microbe Interactions, 2003
Phylogenetic analyses suggest that, among the members of the Eurosid I clade, nitrogen-fixing root nodule symbioses developed multiple times independently, four times with rhizobia and four times with the genus Frankia.
