Integrative Conservation, Volume 4, Issue 4, Page 641-651, December 2025.Key Largo woodrats are a small and endangered island species, whose individuals tend to occur in family groups. Isolation from mainland populations, predation, and habitat fragmentation have caused genetic drift, leading to low overall diversity. Here, we found that a major category 4 hurricane promoted genetic diversity in the Key Largo woodrat ...

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 3, Issue 3, Page 230-243, September 2024.Tropical secondary forest at early sucessional stage had higher diamter growth rate and mortality rate, however, these forests also are more risked to droughts and high temperatures. Rising temperatures and more frequent droughts may decrease the carbon sink capacity of tropical forest ecosystems. Abstract Tropical forests are major carbon sinks on the

Shuitu Baochi Xuebao, 2023 降雨能够改变土壤水分状况进而促进林木蒸腾,然而场降雨量及其持续时间对林木树干液流及其环境控制机制的影响尚不明确。为此,在华北半干旱半湿润区的北京市顺义区共青林场,选取位于河岸生态系统不受土壤水分胁迫的欧美杨(Populus×euramericana)人工林为研究对象,在2019年和2021年生长季,使用TDP热扩散法测量树干液流,同步监测气象及土壤含水量等环境因子。根据对该区长期(2016—2017年、2019年和2021年)降雨数据统计分析结果,将2次降雨脉冲间隔超22.5 ...

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, 2021 为探讨自然环境要素对典型干旱事件的响应与路径，以2019年厄尔尼诺极端干旱事件为背景，在气象站观测数据基础上识别出1个干旱年份（2019年）和1个正常年份（2013年），使用landsat8影像反演了哈尼梯田区2个年份的地表温度（TEM）、土壤水分（TVDI）、植被覆盖（NDVI）、地表水体（NDWI）等自然环境要素数据，进一步探讨了哈尼梯自然环境要素对极端干旱事件的响应状态、相互作用、影响路径等问题。结果表明：哈尼梯田区在极端干旱事件下气温增加了约2℃，植被指数下降了约0.04，土壤水分指数增加了约0.

Process analysis of a heavy rainfall happened in Wenzhou in August, 2014(2014年8月发生于温州市的一次大暴雨过程分析)
Zhejiang Daxue xuebao. Lixue ban, 2015 对2014年8月19日08：00至20日08：00温州市大暴雨过程做技术总结.通过对500 hPa环流分析，利用欧洲中心850 hPa和1 000 hPa细网格风场产品以及雷达拼图、实况雨量分析发现，该次过程为高空槽和低层偏南风急流控制下的系统性强降水，降水的时空分布极不均匀.该次降水过程分为19日白天和夜间2个时段，19日白天的暴雨过程由低层850 hPa中尺度辐合线所造成，辐合线上，有较强的风速辐合.19日夜间的暴雨过程由1 000 hPa风向和风速的辐合造成.该次降水过程降水时段集中、雨强强 ...
