Spatiotemporal studies of black spruce forest soils and implications for the fate of C [PDF]

, 2012
Post-fire storage of carbon (C) in organic-soil horizons was measured in one Canadian and three Alaskan chronosequences in black spruce forests, together spanning stand ages of nearly 200 yrs.

Room‐Temperature Magnetic Skyrmions and Intrinsic Anomalous Hall Effect in a Nodal‐Line Kagomé Ferromagnet MnRhP

Advanced Science, EarlyView.
MnRhP has been identified as a novel kagomé magnet that hosts magnetic skyrmions above room temperature and exhibits a large intrinsic anomalous Hall effect. The latter originates from Berry curvature associated with gapped nodal lines, establishing MnRhP as a promising platform for exploring high‐temperature topological phenomena in both real and ...

Ambient new particle formation parameter indicates potential rise in future events [PDF]

, 2009
Atmospheric new particle formation is a general phenomenon observed over coniferous forests. So far nucleation is described as a function of gaseous sulfuric acid concentration only, which is unable to explain the observed seasonality of nucleation ...

Thermally Modulated Specular Phonon Transport in a High‐Debye‐Temperature Diamond Nanobeam

Advanced Science, EarlyView.
Thermal transport in single‐crystal diamond nanobeams is measured from 140 to 300 K using electro‐thermal micro‐suspended structures. The thermal conductivity shows an increasing deviation from Boltzmann transport predictions assuming fully diffuse boundary scattering at lower temperatures.

Effects of Temperature and Water Availability on Northern European Boreal Forests

Frontiers in Forests and Global Change, 2020
Boreal forests are warming faster than the rest of the planet. Do the benefits of higher temperatures and longer growing seasons for forest productivity exceed the negative effects of more frequent dry spells and heat waves, shifting precipitation ...

Ecophysiological Models of Forest Stand Dynamics [PDF]

, 1991
It is well known that woodlands play a crucial role in stabilizing the natural environment. They greatly influence and regulate hydraulic cycles, and thus the flow of waters and local humidity conditions.

Can forest management based on natural disturbances maintain ecological resilience? [PDF]

, 2006
Given the increasingly global stresses on forests, many ecologists argue that managers must maintain ecological resilience: the capacity of ecosystems to absorb disturbances without undergoing fundamental change.
