人工藻结皮形成过程中表土非降雨型水分吸收的变化情况 [PDF]

open access: yes, 2010
在干旱、半干旱地区,表土非降雨型水分吸收对于植物、生物结皮以及一些小型动物都起着非常重要的作用.本研究对库布齐沙漠中各种水分吸收类型进行了调查,并对人工结皮形成过程中水分吸收的变化进行了跟踪监测.结果发现,在实验区,从空气中吸收的水分占表土水分吸收量的25.07%~39.83%,其主要是通过水汽吸附机制进行.相比之下,表土从深层土壤吸收的水分更多,大约占到水分吸收量的60.17%~74.93%.人工结皮的形成促进了表土水分的吸收,但吸收水分的增加并非在接种后或结皮形成后立即表现出来,而是在结皮形成后 ...

Are Galliformes of the High Himalayas Well Protected? Identifying Conservation Priority Areas Using an Assemblage‐Level Approach 高喜马拉雅地区的鸡形目鸟类是否得到了有效保护?利用群落水平方法确定优先保护区域

open access: yesIntegrative Conservation, EarlyView.
This study investigates distribution patterns of Galliforms in the Indian Himalayas, focusing on factors influencing their occurrence, regions of high diversity and endemism, and their overlap with protected areas. Our study highlights the need for assemblage‐level conservation strategies in high Himalaya which primarily relies on snow leopard‐focused ...

Morphological and Molecular Characterization of Eimeria saudiensis From Arabian Oryx (Oryx leucoryx) Held in Captivity in the Sultanate of Oman 阿曼苏丹国圈养阿拉伯羚羊 (Oryx leucoryx) 体内沙特艾美球虫 (Eimeria saudiensis) 的形态学与分子特征

open access: yesWildlife Letters, EarlyView.
Eimeria saudiensis represents a genus of apicomplexan parasites capable of inducing coccidiosis in Arabian oryx. Our research concentrated on the morphological and molecular investigation of Eimeria spp. in the captive oryx herd in Oman. The therapeutic and management practices employed at the Mammals Breeding Center were reassessed to diminish ...

Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China

open access: yesWildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

古尔班通古特沙漠人工林土壤水分及其影响因素 [PDF]

open access: yes, 2009
通过2004年2~12月对古尔班通古特沙漠南缘2年生人工梭梭和沙拐枣混交林内3条典型坡面土壤水分进行了系统监测与研究。结果表明:人工林土壤水分状况受季节性降水、人工林种植密度、地形因子的影响而出现明显的时空分异。在空间上将土壤水分变化划分为三层,0~30cm为活跃层,30~60 cm为次活跃层,60~120 cm为相对稳定层。通过主成分分析,得出地形因子、种植密度对0~30 cm土层土壤水分的影响次序为坡度>坡向>种植密度>高程,30~60 cm土层为坡向>种植密度>坡度>高程,60~120 ...
