Gradient distributions of nitrogen and organic carbon in the soils from inland to tidal flat in the Yellow River Delta [PDF]

, 2014
黄河三角洲是我国典型的通过黄河冲积泥沙填海造陆形成的近代沉积区。区域受到黄河冲积、沉积等自然过程和农业耕种熟化等人类活动的双重影响。本研究通过在黄河三角洲地区内陆到河口海湾不同距离采集典型土壤类型剖面发生层样品，探讨土壤有机碳、总氮等生源要素的空间分布规律，为阐明我国典型海岸带地区陆源碳、氮的输送及循环特征提供基础依据。研究结果表明，黄河三角洲内陆与河口地区呈现出完全不同的土壤碳、氮分布规律。表层土壤碳、氮含量在黄河沿岸及三角洲南部均表现出由陆向海逐级递减的空间分布特征 ...

Effect of primate protection on threatened and endemic vertebrates, plants, ecosystem services, and future climate refugia

Conservation Biology, Volume 39, Issue 5, October 2025.
Abstract Primates, 69% of which are threatened with extinction, are the third most specious order of mammals. We used primates as model taxa to examine the umbrella effects of primates on ecosystem services and the protection of other vertebrates and seed plants in Yunnan Province, China.

晋西黄土区退耕还林后土壤入渗特征及土壤质量评价

Shuitu Baochi Xuebao, 2021
为研究晋西黄土区退耕还林后不同植被覆盖下土壤的入渗特征及土壤质量评价，采用野外双环入渗法测定土壤的入渗特征，并测定不同地类土壤的容重、孔隙度、有机质、全氮等指标，使用相关性分析研究不同类型植被覆盖下土壤的入渗性能及其与土壤理化性质的相关关系，并将各地类的土壤理化性质进行主成分分析。结果表明：（1）植被类型对于土壤渗透速率影响较大，表现为天然次生林>刺槐×油松混交林>刺槐纯林>油松纯林>灌木林地>苹果园地>荒草地>农田（玉米地）。（2）退耕还林后，不同植被类型的土壤理化性质差异显著（P灌木林地>苹果园地 ...

Vegetation dominantly shapes the elevational patterns of archaeal and protistan communities and their ecological functions in the Hengduan Mountains, Tibetan Plateau

Functional Ecology, Volume 39, Issue 9, Page 2327-2341, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract While elevational patterns of soil bacterial and fungal communities in mountain ecosystems have been well documented, the assembly processes of soil archaeal and protistan communities, and their linkage with ecosystem multifunctionality (EMF), remain poorly understood ...

Tree mycorrhizal associations regulate relationships between plant and microbial communities and soil organic carbon stocks at local scales in a temperate forest

Functional Ecology, Volume 39, Issue 6, Page 1550-1566, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests store substantial amounts of soil organic carbon (SOC), but SOC stocks differ strongly between forest ecosystems dominated by arbuscular mycorrhizal (AM) or ectomycorrhizal (EcM) fungi.

Indian Pangolin in Lamjung Requires Urgent Attention 尼泊尔拉姆琼县地区的印度穿山甲急需关注

Wildlife Letters, Volume 2, Issue 4, Page 204-213, December 2024.
This study documented the first evidence of the Indian pangolin in Lamjung district, Nepal, finding three burrows and rescue evidence in Simalchaur Naringhat Community Forest. The burrows identified at an elevation of 530 m and characterized by moderate crown and ground cover (26%–50%), a 25° slope, and predominantly red soil, are indicative of a ...

Changing plant phosphorus acquisition strategies in relation to altered soil phosphorus fractions after wetland drainage

Functional Ecology, Volume 38, Issue 11, Page 2433-2446, November 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phosphorus (P) acquisition strategy is considered to be an intrinsic driver behind plant succession. However, variations in plant P acquisition strategies in connection to soil P fraction changes after wetland drainage remain unclear.
