A prospective study evaluating the correlation between local weather conditions, pollen counts and pruritus of dogs with atopic dermatitis

open access: yesVeterinary Dermatology, Volume 35, Issue 5, Page 500-507, October 2024.
Abstract Background Canine atopic dermatitis (cAD) is a hereditary, generally pruritic and predominantly T‐cell‐driven inflammatory skin disease, involving an interplay between skin barrier abnormalities, allergen sensitisation and microbial dysbiosis.

人工红壤坡面对超大雨强降雨的响应过程

open access: yesShuitu Baochi Xuebao, 2017
为了研究人工红壤坡面对超大雨强降雨的响应过程,利用人工模拟降雨系统和变坡土槽,分别采用140,160,190 mm/h的雨强和10°,15°,20°,25°的坡度,对经过简单人工处理的红壤坡面在超大雨强降雨条件下的产流产沙响应过程进行了试验。结果表明:经过简单人工处理的红壤坡面在140~190 mm/h超大雨强下的土壤侵蚀模数明显低于50~120 mm/h雨强下未进行相应处理的坡面,细沟发育较为缓慢,对坡面土壤的处理方式能够有效提高坡面的抗侵蚀能力。在同雨强下,随着坡度的增加,产流时间先延长后缩短 ...

Demographic and net primary productivity dynamics of primary and secondary tropical forests in Southwest China under a changing climate 气候变化背景下中国西南热带原始林和次生林的群落和净初级生产力动态研究

open access: yesIntegrative 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

泾河南小河沟流域自然降雨特性

open access: yesShuitu Baochi Xuebao, 2017
采用德国HSC-OTT Persivel32激光雨滴谱探测仪监测南小河沟流域自然降雨的雨滴谱,分析不同雨型自然降雨雨滴特征及其分布规律,并分析了降雨特性各要素间的相互关系。结果表明:(1)该区自然降雨雨滴直径集中在0.3~1.5 mm,与黄土高原利用传统的滤纸色斑法测定结果基本一致,但略小于东北和闽南地区 ...

Moving beyond the pathology of policies pushing species toward extinction: The case of spectacled flying foxes in Australia 摆脱将物种推向灭绝的政策症候——以澳大利亚眼镜狐蝠为例

open access: yesIntegrative Conservation, Volume 3, Issue 2, Page 87-103, June 2024.
Some extinctions can be prevented if impediments to protection of threatened species are overcome. Policies and practices have failed endangered species and biodiversity conservation is fraught with impediments such as rhetorical adoption, policy dismantling, circumvention of legislative obligations, and deliberate ignorance of scientific evidence ...

不同降雨强度下地面坡度对红壤坡面土壤侵蚀过程的影响

open access: yesShuitu Baochi Xuebao, 2011
通过室内模拟降雨试验,研究了不同降雨条件下地面坡度对红壤坡面产流过程和侵蚀过程的影响,结果表明,红壤坡面起始产流时间随坡度的增加有所提前,但不明显,坡面起始产流时间的早晚主要受降雨强度控制;坡面径流量随雨强的增大而增大,随坡度的变化比较复杂,在雨强为50mm/h时,径流量随坡度的增加而减小,在雨强为75mm/h时,径流量随坡度的增加先增大后减小;不同降雨强度下各坡度的侵蚀产沙率都是在降雨初期急剧上升,随后以指数下降,形成一个向左倾斜的曲线。坡度对坡面侵蚀产沙的影响随雨强的增大而增强 ...

More problems sampling wildlife with baits: Environmental food resources influence trapping rates 使用诱饵进行野生动物采样的若干问题:环境中的食物资源会影响诱捕率

open access: yesWildlife 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.

移动降雨条件下坡面产流产沙过程试验研究

open access: yesShuitu Baochi Xuebao, 2017
通过对降雨移动方向上不同雨强和降雨历时的研究,揭示移动降雨坡面产流产沙关系及其变化规律,采用2个降雨移动方向(沿径流向上和向下移动)、2个雨强(1.35,2.75 mm/min)和2个降雨历时(60,120 min)在室内进行模拟移动降雨试验,分析不同降雨移动方向、不同雨强和降雨历时坡面产流产沙特征。结果表明:(1)向上移动降雨,相同历时(相同雨强)条件下,大雨强(长降雨历时)初始产流时间为140 s(240 s),比小雨强(短降雨历时)提前165 s(65 s)。(2)向下移动降雨,雨强越大 ...
