Seasonal Habitat Selection by a Threatened Ungulate in an Industrializing Boreal Landscape
Animal Conservation, EarlyView.Understanding habitat selection by Threatened wood bison in landscapes characterized by anthropogenic disturbance is important for conservation planning. During summer and winter, bison selected for linear (e.g., roads, seismic lines, pipelines) and polygonal (e.g., well sites) disturbances, unless there were high densities of linear features.

Archaeometry, EarlyView.ABSTRACT New radiocarbon determinations from rice grains and bamboo have been obtained from Non Ban Jak, Northeast Thailand. These, along with charcoal, date a late Iron Age building sequence. The results come from short‐lived species and charcoal with potential inbuilt age. We built a series of Bayesian models to obtain a reliable chronology.

The Role of Stomatal Traits and Epicuticular Wax in Resistance to Mycosphaerella fijiensis in Banana and Plantain (Musa spp.) [PDF]
Tropicultura, 1997 Three soil tillage practices - summer ploughing, autumn ploughing and chisel - have been evaluated through their effect on soil physical characteristics and on water content during three months after wheat seeding.

Investigation of Material Removal Mechanism in Grinding: A Single Grit Approach
This thesis has investigated material removal mechanisms in grinding by considering single grit workpiece interaction. The investigation was performed both experimentally and using finite element simulation.

Boreas, EarlyView.Our knowledge of the Early Upper Palaeolithic occupation in northern central Europe is very limited, and recent research at the open‐air site of Friedrichsdorf‐Seulberg in Hesse, Germany, provides important new information on the Aurignacian. The site is rather small (26.5 m2) and spatial analysis identified a central hearth with two associated ...

Conservation Biology, EarlyView.Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.
