Shuitu Baochi Xuebao, 2017 利用遂宁水土保持试验站5个径流小区1984—2015年次降雨和径流输沙数据，基于降雨过程定量划分出4种雨型，分析了雨型对不同坡度坡耕地产流产沙的作用。结果表明：径流深与各时段最大雨强均呈极显著相关（p＜0.01），随着坡度的增加，最大相关系数所对应的雨强时段越短；冲刷量均与I平均呈极显著相关，且相关系数最大。径流深、冲刷量与雨强拟合关系均为幂函数，分别为“凸型”和“凹型”增函数，且拟合度区间分别为[0.79，0.88]和[0.90，0.97]，说明冲刷量和雨强的关系更密切 ...

Integrative Conservation, Volume 4, Issue 3, Page 334-338, September 2025.This study reports four rare events of spiders preying on vertebrates in the Xishuangbanna Tropical Botanical Garden, Southwest China. The predators included a giant golden orb‐weaver, huntsman spiders, and a wandering spider, while the prey consisted of a small bird, a blind snake, a gecko, and a tiny shrew.

Shuitu Baochi Xuebao, 2006 为了研究三峡地区花岗岩林地优先流影响因子，在长江三峡地区曲溪小流域内选定的实验坡面下部，垂直开挖了一个长度为2．9m、深度为2．60m的土壤剖面。在降雨过程中观察优先流过程，分析降雨对优先流的影响。同时对该地区的土壤物理性质和土壤渗透特性进行了测定，分析其对优先流的影响。分析结果表明，影响长江三峡花岗岩区优先流产流的降雨量在26mm（24h降雨量）以上。长江三峡库区的降雨可分为递减降雨型、均匀降雨型、突发降雨型及峰值降雨型4种类型，不同降雨类型对应的优先流过程都表现出相应的降雨过程特征 ...

Multiple global change factors alter the scaling of nitrogen to phosphorus in alpine plants
Functional Ecology, Volume 39, Issue 8, Page 2044-2055, August 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometry and allometry of nitrogen (N) and phosphorus (P) reflect nutrient absorption and dynamic allocation by plants, and can be regulated by global change factors (e.g. nitrogen enrichment, climate warming and altered precipitation). Yet, how multiple global

Predicting Democracy Support in the Middle East and North Africa
World Affairs, Volume 188, Issue 3, Fall 2025.ABSTRACT Democracy support among Arab citizens has decreased noticeably in the past decade. The Arab Barometer data demonstrates more than an average of 15–30 points drop‐in democracy support depending on the country considered. The present research utilizes the seventh wave data set offered by the Arab Barometer conducted between October 2021 and July

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

Big Cat Mortality in Subsistence Hunts in Amazonia 亚马孙雨林地区生计狩猎中的大型猫科动物致死情况研究
Wildlife Letters, Volume 3, Issue 1, Page 16-21, March 2025.We use data from a participatory biodiversity monitoring program to estimate the annual mortality of jaguars and pumas resulting from subsistence hunts in two Amazonian Extractive Reserves. We estimate that around 50 big cats are killed annually in the study area, which is consistent with an independent estimate for the same area and within the same ...

The need for carbon finance schemes to tackle overexploitation of tropical forest wildlife
Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Defaunation of tropical forests, particularly from unsustainable hunting, has diminished populations of key seed dispersers for many tree species, driving shifts in forest community composition toward small‐fruited or wind‐dispersed trees with low wood density. Such shifts can reduce aboveground biomass, prompting calls for overexploitation to
