FEDERAL GRAZING REFORM AND AVOIDABLE RISK [PDF]

Recent rangeland reform attempts have increased ranchers'Â’ uncertainty of retaining grazing permits on federal land. This uncertainty is analyzed with a model of grazing on federal land.

Harnessing Phase Separation for the Development of High‐Performance Hydrogels

Advanced Science, EarlyView.
ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...

Grazing intensity significantly affects belowground carbon and nitrogen cycling in grassland ecosystems: a meta-analysis

, 2017
Livestock grazing activities potentially alter ecosystem carbon (C) and nitrogen (N) cycles in grassland ecosystems. Despite the fact that numerous individual studies and a few meta-analyses had been conducted, how grazing, especially its intensity ...

Non‐Equilibrium Synthesis of Whitlockite Assisted by Localized H2O Vapor Pressure

Advanced Science, EarlyView.
A carbon substrate acts as a microheater during intense pulsed light irradiation, enabling rapid heating and cooling for whitlockite formation. In contrast to conventional white ceramic synthesis with weak photothermal response, this platform concentrates thermal energy locally and promotes phase‐selective crystallization under ultrafast ...

The ecological effects of grazing by the White Rhino (Ceratotherium simum simum) at a landscape scale [PDF]

, 2005
In this thesis I generated hypotheses concerning the top down effect of grazing ungulates on grass communities and fire behavior from work done within grazing exclosures in Hluhluwe iMfolozi Park.

Theretofore Highest Efficiency in Vacuum‐Deposited Organic Solar Cells Originating From Triarylamine‐Based Small‐Molecule Donors Containing Fused Heterocycle Units

Advanced Science, EarlyView.
Fused‐ring engineering unlocks record efficiency in vacuum‐deposited organic solar cells. By replacing linear π‐bridges with fused‐ring analogues in triarylamine‐based donors, we achieve enhanced molecular planarity, red‐shift optical absorption, minimize energy loss and optimized phase separation.

Grazing strategy shifts mitigate the negative effects of drought on grassland productivity in Inner Mongolia

Ecological Indicators
To mitigate grassland degradation, China has implemented a series of grazing-centered protection policies. However, how different grazing policies regulate grazing intensity to influence the effects of drought on grassland productivity in Inner Mongolia ...
