Effect of primate protection on threatened and endemic vertebrates, plants, ecosystem services, and future climate refugia

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract Primates, 69% of which are threatened with extinction, are the third most specious order of mammals. We used primates as model taxa to examine the umbrella effects of primates on ecosystem services and the protection of other vertebrates and seed plants in Yunnan Province, China.

Ecological Restoration of Rubber Monocultures: Strategies for Biodiversity and Ecosystem Recovery in Tropical Regions 题目:如何将橡胶林恢复为多样森林?

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 345-353, September 2025.
Restoration of monoculture in protected and marginal areas can be organized into two phases (1) identification and prioritization of restoration sites based on remote sensing or field survey then assessing degradation level, and (2) implementation of appropriate restoration interventions.

Reoccurrence of Dust Storms in South Asia and Their Implications for Vegetation Health 南亚沙尘暴的再次出现及其对植被健康的影响

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.
Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

Effects of Shifting Cultivation on the Western Hoolock Gibbon (Hoolock hoolock) in Western Myanmar 刀耕火种对缅甸西部西部白眉长臂猿 (Hoolock hoolock) 的影响摘要

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 503-513, September 2025.
Fire occurrence increased with proximity to roads and villages, indicating that human access and activity are major drivers of fire risk. We analyzed spatial patterns of fire in relation to human settlements. Our findings highlight the need for fire management strategies that consider accessibility and human presence in conservation planning.

水土保持林有效覆盖率及其确定方法的研究

open access: yesShuitu Baochi Xuebao, 1996
水土保持林有效覆盖率是水土保持林建设中的一个重要指标。该术语虽出现较早且已被逐渐采用,但由于缺乏严格的定义和统一确定标准,以至水土保持林有效覆盖率数值从30%~75%,这严重影响了水土流失区林业生产的宏观决策。通过对水土保持林系统的详细分析,定义了水土保持林有效覆盖率为在一定防护范围内的土壤流失量等于允许流失量时的森林覆盖率:ae-bF=SLA。并指出有效覆盖率的确定涉及2个方面、3个步骤;水土保持林有效覆盖率为时间和空间的函数。此外还以黄土高原水土流失区为例,介绍了水土保持林有效覆盖率的确定方法。

Interdependencies between Indigenous peoples, local communities, and freshwater systems in a changing Amazon

open access: yesConservation Biology, Volume 39, Issue 3, June 2025.
Abstract Globally, Indigenous peoples and local communities (IPs and LCs) are fighting for the recognition of their knowledge and decision‐making authority in freshwater conservation. In the Amazon, decision‐making around freshwater management and conservation has often overlooked Indigenous and local knowledge (ILK) and the connections between ...

黄土高原水土保持建设的环境效应

open access: yesShuitu Baochi Xuebao, 2003
水土保持是黄土高原生态恢复和重建的基础,但在有效拦蓄径流和泥沙的同时,水土保持建设改变了水分和养分的静态分布格局和动态循环过程,并由此对区域的环境产生影响。分析了水土保持建设对水文环境和土壤环境的影响及其研究动态。不同水保措施都能在一定程度上调节和控制水文过程,改善流域的水质,提高土壤的质量,提高土壤的含水率;而人工林草植被不同程度地减少了土壤含水率。同时对黄河断流以及土壤干层与水土保持建设的关系进行了探讨。

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition

open access: yesAntipode, Volume 57, Issue 3, Page 830-861, May 2025.
Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.
