Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

晋西黄土区典型林地土壤水分变化特征

open access: yesShuitu Baochi Xuebao, 2021
选择晋西黄土区蔡家川流域5种典型林地(山杨×辽东栎天然次生林、人工油松×刺槐混交林、人工油松林、人工刺槐林、人工侧柏林)作为研究对象,在每块样地中心布设1个土壤水分观测点,采用TRIME-TDR土壤水分测定仪定位观测2016—2018年1—12月的土壤体积含水量,测定深度为200 cm,每20 cm为1个测层,每月分上、中、下旬进行土壤水分含量观测,分析不同林地类型土壤水分年内变化规律和土壤水分垂直变化规律。结果表明:(1)研究区不同林地土壤水分年内变化可以划分为稳定期(1—3月)、波动期(4—6月 ...

梭罗的极简主义生活智慧及其启示——基于生态幸福观的视角 [PDF]

open access: yes, 2017
极简主义原是西方一种现代艺术流派,其核心理念是崇尚简约。而作为一种生活方式的极简主义,梭罗早在19世纪就践行过:他通过对“步行”“奢侈”与“文明”的深刻反思,认为应简化人的物质需求,倡导追求精神上的自由,从而促进人与自然和谐共生。当前正处于生态危机的时代,亟需提倡这样一种极简主义的生活方式。梭罗的极简主义生活智慧对于我国的生态文明建设具有重要的启示作用,有助于实现全社会的生态幸福。2016年度教育部人文社会科学研究一般项目“马克思主义道德观与道德相对主义批判”(16YJA710028 ...

Role of forest edges and other seminatural linear landscape features in structuring wild bee habitat connectivity in intensively managed landscapes

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Pollinator conservation schemes typically focus on conserving existing, restoring degraded, or creating new wild bee habitats. Their effectiveness depends on dispersal corridors enabling habitat colonization by bees. However, the role of seminatural linear landscape structures (LLS) in connecting pollinator communities across intensively ...

大青山不同林地类型土壤特性及其水源涵养功能

open access: yesShuitu Baochi Xuebao, 2008
对内蒙古大青山4种林地类型的土壤特性、凋落物持水量及林地土壤贮水性能进行了研究。结果表明:①林地间土壤容重和孔隙度差异较大,容重大小依次为油松人工林>虎榛子灌丛林>落叶松人工林>白桦山杨天然次生林;总孔隙大小依次为白桦山杨天然次生林>落叶松人工林>虎榛子灌丛林>油松人工林;②林地间凋落物蓄积量和最大持水率差异较大,蓄积量大小依次为落叶松人工林>白桦山杨天然次生林>虎榛子灌丛林>油松人工林;最大持水率大小依次为落叶松人工林>白桦山杨天然次生林>虎榛子灌丛林>油松人工林;③依据林地总贮水量的大小 ...

Reoccurrence of Dust Storms in South Asia and Their Implications for Vegetation Health 南亚沙尘暴的再次出现及其对植被健康的影响

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.
Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

The Two Faces of Introgression in Conservation Biology 基因渗入在保育生物学中的双重面貌

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 339-344, September 2025.
Conservation biologist need to take into account the various aspects of introgression in their attempts to protect the species integrity and evolutionary potential of threatened species. To do so, they have to overcome the bias created by the Mayrian species concept that considers species as having distinct gene pools.

广东湛江红树林自然保护区及附近海岸互花米草入侵与红树林保护 [PDF]

open access: yes, 2018
对广东湛江红树林自然保护区范围内和周边区域的外来植物互花米草(Spartina alterniflora)的生长分布进行了实地调查。结果显示,雷州半岛东、西海岸均有互花米草的分布,总面积达12.6 hm~2,徐闻海安新港码头是互花米草在中国大陆分布的最南端。调查发现,互花米草和乡土红树植物的生态位重叠,虽然致密的红树林内未见互花米草的生长分布,但互花米草比乡土红树植物更耐淹水,表现为在光滩前沿低潮位仅有互花米草的分布。鉴于互花米草在雷州半岛分布范围广、生境类型多样、扩散增长迅速的现状 ...
