Carbon Stock and Environmental Variations of Typical Plantations in Mufu Mountain in Hubei Province, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.

Drought impacts on ecosystem functions of the U.S. National Forests and Grasslands: Part I evaluation of a water and carbon balance model [PDF]

open access: yes, 2015
Understanding and quantitatively evaluating the regional impacts of climate change and variability (e.g., droughts) on forest ecosystem functions (i.e., water yield, evapotranspiration, and productivity) and services (e.g., fresh water supply and carbon ...

LRRK2 as a Potential Disease‐Modifying Target in Sporadic Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract A growing understanding of the role that leucine‐rich repeat kinase 2 (LRRK2) plays in Parkinson's disease (PD) supports continued focus on this enzyme as a therapeutic target for PD. Accumulating evidence suggests that there are phenotypic, neuropathologic, and biological similarities between sporadic PD (sPD) and familial forms in which ...

Quality of life and healthcare resource utilization among adult patients with short bowel syndrome: A mixed‐methods study leveraging an integrated database

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background Short bowel syndrome (SBS) is a chronic condition requiring parenteral nutrition (PN) support and multidisciplinary management. However, disparities in access to care and standardized treatment pathways, in addition to economic burden, remain considerable for patients.

Contrasting Performance of the Remotely-Derived GPP Products over Different Climate Zones across China

open access: yesRemote Sensing, 2019
Precise quantification of terrestrial gross primary production (GPP) has been recognized as one of the most important components in understanding the carbon balance between the biosphere and the atmosphere.

Not just ‘super‐predators': human behaviour shapes wildlife behavioural responses across avoidance, tolerance and attraction

open access: yesOikos, EarlyView.
Humans are thought to have a disproportionately negative impact on wildlife and are viewed by some as the ultimate ‘super predator'. This view implies that wild animals perceive humans primarily as predators. However, a growing body of evidence shows that wildlife can have remarkable tolerance for, or even attraction to, humans.

Green public procurement of certified wood : impact on international trade and global welfare [PDF]

open access: yes, 2015
This paper investigates the impact of green public procurement (governments’ purchases) of certified wood in the EU. A spatial partial price equilibrium model is developed to analyse whether this policy impacts interregional trade flows of wood and other

Chiral Properties of Pseudoscalar Mesons on a Quenched $20^4$ Lattice with Overlap Fermions [PDF]

open access: yes, 2001
The chiral properties of the pseudoscalar mesons are studied numerically on a quenched $20^4$ lattice with the overlap fermion. We elucidate the role of the zero modes in the meson propagators, particularly that of the pseudoscalar meson.
