Trait‐Based Prediction of Extinction Risk and Conservation Strategy for Traditional Chinese Medicinal Plants in China 基于性状的中药植物灭绝风险预测与保护策略研究

open access: yesIntegrative Conservation, EarlyView.
Our research allows us to understand the predictors of extinction risk in traditional Chinese medicinal (TCM) plant species with known threat status, and incorporate this knowledge to predict other TCM plants with unknown conservation status in China so as to improve the overall effectiveness of conservation strategies.

Existence of nontrivial solutions for a quasilinear Schrodinger equations with sign-changing potential

open access: yesElectronic Journal of Differential Equations, 2014
In this article we consider the quasilinear Schrodinger equation where the potential is sign-changing. We employ a mountain pass argument without compactness conditions to obtain the existence of a nontrivial solution.

Experimental Assessment of the Effects of Substrate Choice on the Duration of Chemical Signals in Fecal Scent‐Marks of Free‐Ranging Iberian Wolves

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Chemical communication, typically based on feces, urine, and glandular secretions, often deposited as substrate scent marks, plays a key role in social organization and communication among many mammals, especially carnivores. This study assesses experimentally whether the type of substrate chosen for fecal deposition and the temperature ...

The Art of Reception: Field Visits as Microcosms for Development Interventions of Non‐Governmental Organisations in Uganda

open access: yesJournal of International Development, EarlyView.
ABSTRACT Field visits are common phenomena with non‐governmental organisations in Uganda. During these visits, Ugandan national staff guide visitors on series of meetings and interactions in the field. Following an actor‐oriented approach and drawing on ethnographic data on 14 field visits, this paper understands the field visit as a microcosm for the ...

Assessing Climate Change Impacts on Runoff Variability and Extremes in China Using High‐Resolution Simulations

open access: yesInternational Journal of Climatology, EarlyView.
Future runoff in China shows strong regional and seasonal disparities, with the Southeast basin seeing the largest increase in annual runoff. Wetter summers and drier winters are expected in the south, whilst the northwest will face the opposite. Over 56% of regions are expected to experience more extreme high runoff, and over 40% face intensified low ...
