Organosolv Fractionation of Softwood Biomass for Biofuel and Biorefinery Applications

open access: yesEnergies, 2017
Softwoods represent a significant fraction of the available lignocellulosic biomass for conversion into a variety of bio-based products. Its inherent recalcitrance, however, makes its successful utilization an ongoing challenge.

Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

open access: yesOikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Dendrochronological analysis of the roof of the Nanebevzetí Panny Marie and Sv. Ondřeje church in Staré Hobzí

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2004
The work deals with dendrochronological analysis of the roof truss of parish church in the locality of Stare Hobzi. The dendrochronological analysis gave an integrated view on a complicated development of this building and it helped us to restore the ...

Bioclimatic, demographic and anthropogenic correlates of grizzly bear activity patterns in the Greater Yellowstone Ecosystem

open access: yesOikos, EarlyView.
Plasticity of diel activity rhythms may be a key element for adaptations of wildlife populations to changing environmental conditions. In the last decades, grizzly bears Ursus arctos in the Greater Yellowstone Ecosystem (GYE) have experienced notable environmental fluctuations, including changes in availability of food sources and severe droughts ...

Integrated morphological and physiological plasticity of root for improved seedling growth in Cunninghamia lanceolata and Schima superba under nitrogen deficiency and different NH4+-N to NO3−-N ratio

open access: yesFrontiers in Plant Science
ContextRoot plasticity is an important physiological mechanism for trees to adapt to nitrogen (N) deficiency and the unequal distribution of ammonium nitrogen (NH4+-N) and nitrate nitrogen (NO3−-N) for promoting growth.

Importance of far-infrared mapping in a spiral galaxy: AKARI observation of M81

open access: yes, 2010
The importance of the far-infrared (FIR) mapping is demonstrated for a face-on spiral galaxy, M81, by analyzing its imaging data at 65, 90, and 140 {\mu}m taken by AKARI.

What does coexistence mean? Insight from place‐based trajectories of pastoralists and bears encounters in the Pyrenees

open access: yesPeople and Nature, EarlyView.
Abstract The recovery of large carnivores in Europe raises issues related to sharing landscape with humans. Beyond technical solutions, it is widely recognized that social factors also contribute to shaping coexistence. In this context, scholars increasingly stress the need to adopt place‐based approaches by analysing how humans and wildlife interact ...

Potential drivers of fast growth in Paulownia

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Trees in the genus Paulownia play a crucial role in sustainable forestry, rural economic development, and carbon mitigation due to their rapid growth, exceptional hardwood properties, and prominent carbon sequestration capacity. This review highlights the societal value of Paulownia trees and synthesizes several potential drivers of extraordinarily ...

Efficient, Reversible Lead Adsorption in a Thiol‐Decorated Zirconium‐Metal–Organic Framework

open access: yesSmall, EarlyView.
A thiol‐decorated Zr‐MOF, Zr‐DMSA, efficiently captures Pb(II) from water via mixed S/O chelation enabled by flexible “dangling” ligands, as revealed by solid‐state NMR and pair distribution function analyses. Treatment with 1 M HCl fully reverses Pb binding, regenerating the material for up to 10 consecutive adsorption–desorption cycles.

Printed Liquid Metal–Solid Metal Hybrid Electrodes for Stabilizing Liquid Platinum–Gallium Droplets During Electrocatalysis

open access: yesSmall, EarlyView.
A printed liquid‐metal catalyst platform is developed by confining Pt‐in–Ga liquid metal droplets within a tungsten nanoparticle matrix on porous Mo substrates. This architecture suppresses liquid metal droplet agglomeration and leaching, enabling durable and highly active electrocatalysis for both HER and CO2RR, with Pt‐dependent active motifs ...
