Integrative Conservation, Volume 3, Issue 3, Page 168-182, September 2024.Using long‐term field data, we examined the impact of severe droughts on the health, reproductive success, and behavior of the critically endangered Verreaux's sifaka (Propithecus verreauxi) in Madagascar's seasonally dry tropical forest. Despite reduced availability of high‐quality foods, sifaka exhibited stable body condition and reproductive success,

Shuitu Baochi Xuebao, 2018 为探究滇中高原优势群落常绿阔叶林植被对降雨雨滴动能的影响，于2016年和2017年5—9月，在天然降雨条件下运用自计雨量计和滤纸色斑法，通过定位监测磨盘山常绿阔叶林林外降雨和林内穿透雨特征及其雨滴特性，针对不同降雨条件研究了常绿阔叶林对雨滴动能等特征的影响。结果表明：林外的雨滴个数比林内降雨的雨滴个数多61.7%；随着雨量的增大，雨滴直径分布规律也呈逐渐增大的趋势；在小雨条件下，

Wildlife Letters, Volume 2, Issue 2, Page 83-89, June 2024.In this study, we show that environmental food availability influences wildlife detection probability when using food baits. We sampled small mammals in Borneo with live traps baited with fruit before, during and after the rainforest experienced a mast fruiting event, which drastically altered environmental food availability.

Shuitu Baochi Xuebao, 2018 研究降雨与降雨侵蚀力的时空变化特征及其原因对流域土壤侵蚀监测、评估、预报和治理具有重要意义。以干旱半干旱的渭河流域为研究对象，采用Mann-Kendall检验分析了降雨与降雨侵蚀力的变化趋势；采用启发式分割法对流域降雨量与降雨侵蚀力进行了变异诊断；采用交叉小波分析探究了ENSO（厄尔尼诺-南方涛动）、北极涛动、太阳黑子与降雨以及降雨侵蚀力的联系。结果表明：（1）降雨和降雨侵蚀力均呈下降趋势；（2）华山站和西吉站的降雨量存在变异点，华山站和临洮站的降雨侵蚀力存在变异点 ...

Shuitu Baochi Xuebao, 2020 为研究在长时间降雨侵蚀过程中北京褐土坡面侵蚀特征及其水动力学机制，通过室内人工模拟降雨试验，分别在60，90 mm/h雨强下对褐土坡面进行连续10场次降雨试验，探讨了坡面侵蚀过程中的产流产沙特征及其与水动力学参数间的关系。结果表明：（1）在雨强及次降雨量较一致的条件下，随降雨场次增加坡面次降雨产流量变动较小，而次降雨产沙量变化较大，60，90 mm/h雨强下次降雨产沙量的变异系数为23.94%和59.88%，且第10场降雨的产沙量仅为第1场降雨的59.74%和22.28%；（2）连续降雨条件下 ...

Shuitu Baochi Xuebao, 2022 侵蚀性降雨是引起喀斯特黄壤坡面水土流失的主要动力因子。采用贵州省遵义市浒洋水流域2018—2020年4个径流小区92次侵蚀性降雨产流产沙实测数据,研究次降雨条件下,裸露坡面和块石出露小区对产流产沙的影响。结果表明:(1)侵蚀性降雨可以分为A、B、C 3类,A类降雨是造成喀斯特黄壤坡面土壤侵蚀的主要雨型。侵蚀性降雨的标准为次降雨量＞6.6 mm或I30＞3.6 mm/h。(2)裸露坡面63.27%的侵蚀性降雨径流深＜0.4 mm,66.30%的侵蚀性降雨土壤流失量＜1 g/m2 ...

Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Reintroduced populations are typically considered to progress through establishment, growth, and regulatory phases. However, most reintroduction programs do not monitor intensively enough to test this conceptual model. We studied population indices derived from track activity of 4 threatened species (greater bilby [Macrotis lagotis], burrowing

Shuitu Baochi Xuebao, 2017 通过对山西省长治市白马小流域的1个标准小区和4个植物措施小区近5 a（2006—2010年）的降雨和径流泥沙观测，研究太行山土石山区的降雨特征以及不同类型降雨对典型植物措施小区径流泥沙的影响。结果表明：（1）太行山土石山区侵蚀性降雨主要集中于5—8月份，7—8月份侵蚀性降雨次数占侵蚀性降雨总次数的54.55%，侵蚀性降雨量占侵蚀性降雨总量的61.19%，故该时期是防治水土流失的关键时期；（2）径流量R与降雨量P、最大30 min降雨强度I30、降雨量和最大30 min降雨强度的乘积PI30呈正相关且在0.

Shuitu Baochi Xuebao, 2020 为研究雨型对华北土石山区坡面土壤侵蚀的影响，通过室内人工模拟降雨试验，以华北土石山区主要土壤类型黄土性褐土和石灰性褐土为研究对象，设计次降雨中平均降雨强度和降雨量相同的3种不同降雨类型（均匀型、增加型、减弱型对应的降雨强度组合分别为60，30~60~90，90~60~30 mm/h），分析不同雨型下华北土石山区坡面产流产沙的变化规律。结果表明：（1）不同雨型的产流时间与起始阶段降雨强度呈负相关，增加型降雨的坡面产流时间最长，且分别为均匀型和减弱型的1.98，4.15倍；减弱型降雨的总径流量和总侵蚀量最大，

Wildlife Letters, Volume 2, Issue 1, Page 17-22, March 2024.Temminck's pangolin faces conservation threats, mainly habitat fragmentation, poaching, and trafficking. The study assessed the ecology, status, and distribution of Temminck's pangolin in Hwange National Park and directly sighted seven specimens. Biotic and abiotic factors influence pangolin distribution inside and outside protected areas.
