New Phytologist, Volume 247, Issue 3, Page 1117-1128, August 2025.Summary Environmental changes and their effects are among the most pressing topics of today's ecological research. Shrublands, although widespread across the globe, remain understudied in this respect. We conducted a global meta‐analysis of 81 shrubland sites subjected to experimental warming, shifts in precipitation (e.g.

Integrative Conservation, Volume 4, Issue 2, Page 188-204, June 2025.We assessed the distribution of 14 threatened agamid lizard species using Species Distribution Modeling to identify hotspots for these species' conservation. Based on the results, high‐priority areas of threatened agamids were projected to occur specially in the wet zone.

Gongye shui chuli, 2020 通过在原水解酸化池中安装弹性填料并增加泥水分离池，将CASS池剩余污泥排放至水解酸化池等改造措施，采用复合水解酸化-CASS组合工艺处理高比例印染废水。改造后的运行结果表明，复合水解酸化池显著提高了废水的可生化性，BOD5/COD能稳定达到0.4左右，并使得后续的CASS工艺极大提升了对废水中有机污染物的去除率。改造后的系统出水稳定，达到《城镇污水处理厂污染物排放标准》（GB 18918-2002）一级A排放标准。

Using the IUCN Environmental Impact Classification for Alien Taxa to inform decision‐making
Conservation Biology, Volume 38, Issue 2, April 2024.Abstract The Environmental Impact Classification for Alien Taxa (EICAT) is an important tool for biological invasion policy and management and has been adopted as an International Union for Conservation of Nature (IUCN) standard to measure the severity of environmental impacts caused by organisms living outside their native ranges.

Jingshui jishu【目的】目前我国在农村生活污水治理工作方面已经取得了很大的提高与成效，但也不可避免存在许多问题，其中我国农村大量建成的单一厌氧池普遍存在氨氮去除率低的问题。【方法】对此，本文以增城区某农污站点为试点，将厌氧池改造为厌氧-好氧(AO)工艺并进行处理效果及经济分析。【结果】改造后出水氨氮的平均去除率由13.64%的提高至67.00%;化学需氧量(COD)平均去除率由63.14%提高至82.28%;悬浮物(SS)平均去除率由60.69%提升至76.15%;总磷及总氮去除率也分别达到了93.
