Proglacial lake records of Holocene glacier behaviour and catchment processes in Slettedalen, Northeast Greenland

Journal of Quaternary Science, EarlyView.
ABSTRACT Constraining Arctic catchment response to Holocene climate change is vital for understanding future environments. We present detailed sedimentological, geochemical and grain size end‐member analysis of two Holocene (~7.0 ka to present) lake sequences, S1 and S2, close to Zackenberg, Northeast Greenland.

A new, ~4500‐year varve record and high‐resolution tephrochronology from lake Hämälänlampi, eastern Finland, provides age constraints for the Furnas C and the Glen Garry/Askja A‐2000 eruptions

Journal of Quaternary Science, EarlyView.
ABSTRACT The northern European distal cryptotephra framework is constantly developing both in terms of identification of new tephra horizons and improved age constraints for the already well‐established tephra marker horizons. However, many prehistoric tephra layers have only been dated by the radiocarbon method, with its inherent problems.

Predicting Snow Density

, 2013
Snow density is an important measure in hydrological applications. It is used to convert snow depth to the snow water equivalent (SWE). A model developed by Sturm et al. (2010) predicts the snow density by using snow depth, the snow age and a snow class defined by the location.

Development of Selective Plane Illumination Surface Enhanced Raman Scattering Spectral Microscopy for Improved Cellular Imaging

Journal of Raman Spectroscopy, EarlyView.
Selective plane illumination (SPI) is combined with SERS spectral imaging to reduce background, improve image contrast, and enable improved spectroscopy from molecules on the surface of nanoparticles. This approach provides improved imaging and spectroscopy from nanoparticles in complex environments, such as biological cells.

Concentration and composition of condensed tannins in leaves from fodder trees and shrubs in Pakistan

JSFA reports, EarlyView.
Abstract Background The lack of dependable, high‐quality forage and animal feedstuffs in many areas of the world hampers livestock production. In these regions, farmers often rely on native fodder tree and shrub leaves as a forage source for their animals with little or no information available on nutritional factors of these feedstuffs.

Density‐dependent habitat selection in plains bison

The Journal of Wildlife Management, EarlyView.
Using GPS collar data, we tested whether habitat selection of plains bison in Grasslands National Park, Canada, was density dependent. Bison selected for areas of high vegetation productivity far from human activity when population density was low and increased use of lower productivity habitat closer to disturbance as density increased.
