青藏高原东缘不同林龄云杉林冬季土壤呼吸特征

open access: yes, 2009
采用动态密闭气室红外CO2分析法(IRGA),连续定位测定青藏高原东部4种不同恢复阶段的人工云杉林和原始云杉林在冬季(2007.11.01~2008.03.31)的土壤呼吸,用挖壕沟法同步区分土壤自养呼吸和异养呼吸,并同步测定土壤5cm温度和水分.结果表明,土壤5cm温度与冬季土壤呼吸速率具有显著的正指数相关关系,土壤含水量与冬季土壤呼吸的相关性不明显.亚高山针叶林冬季土壤呼吸温度系数Q10值为3.1803~6.5469,不同年龄阶段针叶林的Q10值大小依次为:35a人工云杉林>47a人工云杉林 ...

Genetic diversity of the critically endangered Blue‐crowned laughingthrush (Garrulax courtoisi) 极度濒危的蓝冠噪鹛 (Garrulax courtoisi) 的遗传多样性

open access: yesWildlife Letters, Volume 2, Issue 2, Page 73-82, June 2024.
Molecular markers are widely used in conservation genetics of wildlife. A total of 15 novel microsatellite loci with high polymorphism of Blue‐crowned laughingthrush were developed in this study. The genetic diversity level of wild individuals was higher than two captive populations including Ocean Park Hong Kong and Nanchang Zoo. The genetic diversity

Conservation and mitigation approaches for human–gray wolf (Canis lupus) conflicts in Shigar Valley, Northern Pakistan 巴基斯坦北部希加尔河谷地区人与灰狼(Canis lupus)冲突的保护与缓解方法

open access: yesWildlife Letters, Volume 2, Issue 1, Page 33-43, March 2024.
Human–carnivore conflicts are major global challenges. In Northern Pakistan, the conflict between humans and gray wolves poses a significant threat to their populations, primarily due to livestock predation. This study in the Shigar valley from 2019 to 2021 revealed a link between higher altitudes and more wolf attacks on livestock.

1736~1999年西安与汉中地区年冬季平均气温序列重建

open access: yes, 2003
基于现代气象资料所建立的西安、汉中地区冬季降雪天数与年冬季平均气温之间的相关关系 ,根据清代档案所记载的西安与汉中地区冬季降雪日数 ,恢复了西安与汉中地区 1736~ 1910年的年冬季平均气温 ,重建了 1736~ 1999年西安与汉中地区年冬季平均气温序列。序列分析表明 ,这两个地区年冬季平均气温变化趋势一致 :18世纪和 2 0世纪为暖期 ,19世纪为冷期 ,且 2 0世纪的增暖趋势明显。与利用树轮重建的镇安初春 (3~ 4月 )温度序列对比分析表明 :西安 ...
