Functional Ecology, Volume 39, Issue 11, Page 3255-3268, November 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract The biotic resistance hypothesis (BRH) of Elton posits that diverse communities are more resistant to biological invasions. While the effects of climatic stresses and human disturbances on community invasibility have been extensively studied individually, their combined

Integrative Conservation, Volume 4, Issue 3, Page 302-309, September 2025.We discussed the key assumptions of Distance sampling that were considered hard to meet in mountainous terrains and potential solutions for them. Our survey yielded comparable estimates from distance sampling and double‐observer survey, although the confidence interval from distance sampling was broader.

Integrative Conservation, Volume 4, Issue 3, Page 503-513, September 2025.Fire occurrence increased with proximity to roads and villages, indicating that human access and activity are major drivers of fire risk. We analyzed spatial patterns of fire in relation to human settlements. Our findings highlight the need for fire management strategies that consider accessibility and human presence in conservation planning.

, 2007 对干扰条件下古尔班通古特沙漠土壤养分空间分异特征进行了研究。分析土壤养分的变化趋势,及干扰与植被和土壤养分之间的关系。研究表明:沙漠边缘至沙漠腹地,全N、全P和全K含量、EC、总盐,可溶性离子HCO3-、SO42-及Ca2+呈增加趋势。CO32-、Mg2+、Cl-、Na+4种离子含量较低,变化规律不明显。除全K含量随公路里程呈较连续的增加外,其他养分条件在公路里程25—75km,80—125km和大于125km的范围内的变化趋势都呈现高→低→显著增高的波动过程,分析表明这种波动性的变化是由干扰造成的 ...

, 2006 古尔班通古特沙漠作为北疆冬季牧场,普遍承受牲畜的践踏干扰,研究表明:动物践踏干扰导致各种类型生物结皮的覆盖度有不同程度的降低,干扰主要集中于结皮层(0~2 cm)。微生物各类群对践踏干扰的反应具差异性,真菌与干扰的相关性最高,细菌和放线菌对干扰不敏感。践踏干扰改变了微生物各类群在垄间低地的数量垂直分布格局,但并未改变微生物区系组成。有机质对干扰不敏感,仍随土层加深而递减,在结皮层(0~2 cm ...

, 1990 对不可压缩层流二维干扰流动,本文提出一个干扰流动(IF)理论。IF理论要点为:1)干扰流动沿主流的法向被分为三层即粘性层、干扰层和无粘层,引进了法向动量交换为主导过程的干扰层概念。2)利用力学守恒律、三层匹配关系及文中引进的干扰模型,把三层的空间尺度及惯性-粘性诸力的数置级表示为单参数m的函数 ...

Dianci bileiqi, 2012 金属氧化物避雷器现场带电测试经常由于相间干扰的缘故,难以准确测量其阻性电流。以最普遍的三相直线排列的氧化物避雷器为研究对象,对其在相间干扰影响下的运行特征进行了分析,得出其全电流的误差特性,并研究了边相补偿的原理和实际应用,指出了在实际的运行环境中,要准确测得阻性电流分量是非常困难的,也是不必要的,带电测试的关键是确定阻性电流相关量的增量及其变化趋势。
