Cedrus libani: A promising tree species for Central European forestry facing climate change?

Considering climate change, the discussion intensifies whether and to what extent exotic tree species should be taken into account for forest cultivation, especially when indigenous species are no longer able to fulfill essential forest functions. In this ...

Two ancient human genomes reveal Polynesian ancestry among the indigenous Botocudos of Brazil

Jeffrey David Jensen

Summary Understanding the peopling of the Americas remains an important and challenging question. Here, we present 14C dates, and morphological, isotopic and genomic sequence data from two human skulls from the state of Minas Gerais, Brazil, part of one of ...

Reconstructing Evolving Tree Structures in Time Lapse Sequences

Pascal Fua, Engin Türetken, Raphael Sznitman, Jan Kybic, Przemyslaw Rafal Glowacki, Miguel Amável Dos Santos Pinheiro, Daniel Lebrecht

We propose an approach to reconstructing tree structures that evolve over time in 2D images and 3D image stacks such as neuronal axons or plant branches. Instead of reconstructing structures in each image independently, we do so for all images simultaneous ...

Nitrogen limitation and microbial diversity at the treeline

Alexandre Buttler, Julien Roy, Aurélie Thébault

Tree growth limitation at treeline has mainly been studied in terms of carbon limitation while effects and mechanisms of potential nitrogen (N) limitation are barely known, especially in the southern hemisphere. We investigated how soil abiotic properties ...

Glacial-interglacial dynamics of Antarctic firn columns: Comparison between simulations and ice core air-δ15N measurements

Jérôme Chappellaz

Correct estimation of the firn lock-in depth is essential for correctly linking gas and ice chronologies in ice core studies. Here, two approaches to constrain the firn depth evolution in Antarctica are presented over the last deglaciation: outputs of a fi ...

High-resolution glacial and deglacial record of atmospheric methane by continuous-flow and laser spectrometer analysis along the NEEM ice core

Jérôme Chappellaz, Daniele Romanini

The Greenland NEEM (North Greenland Eemian Ice Drilling) operation in 2010 provided the first opportunity to combine trace-gas measurements by laser spectroscopic instruments and continuous-flow analysis along a freshly drilled ice core in a field-based se ...

The Antarctic ice core chronology (AICC2012): An optimized multi-parameter and multi-site dating approach for the last 120 thousand years

Jérôme Chappellaz

The deep polar ice cores provide reference records commonly employed in global correlation of past climate events. However, temporal divergences reaching up to several thousand years (ka) exist between ice cores over the last climatic cycle. In this contex ...

Uranium-series dating and growth characteristics of the deep-sea scleractinian coral: Enallopsammia rostrata from the Equatorial Pacific

Anders Meibom

The deep-sea coral, Enallopsammia rostrata, a member of the Dendrophylliidae family, is a major structure-forming species that creates massive dendroid colonies, up to 1 m wide and 0.5 m tall. Living colonies of E. rostrata have been collected using the PI ...

Climate- and human-induced hydrological change since AD 800 in an ombrotrophic mire in Pomerania (N Poland) tracked by testate amoebae, macro-fossils, pollen, and tree-rings of pine

Mariusz Lamentowicz

This high-resolution, multiproxy, palaeoenvironmental study of the Slowinskie Blota raised bog in N Poland, 10km from the Baltic Sea, covering the last 1200 years reveals different aspects of environmental change in a range of spatial scales from local to ...

Studying sulfur functional groups in Norway spruce year rings using S L-edge total electron yield spectroscopy

Christian Ludwig, Rudolf Paul Wilhelm Jozef Struis

Profiles of the major sulfur functional groups in mature Norway spruce wood tissue have been established for the first time. The big challenge was the development of a method suitable for sulfur speciation in samples with very low sulfur content (
