Sewn boats in the Qatar Museums collection, Doha: baggāras and kettuvallams as records of a western Indian Ocean technological tradition

open access: yesInternational Journal of Nautical Archaeology, Volume 49, Issue 2, Page 371-405, September 2020., 2020
Abstract Vernacular sewn boats from southern Iran and Kerala, India, in the collection of Qatar Museums are documented and their construction described. The Iranian baggāras are unique preservations of sewn boats from the Arabian‐Persian Gulf, notable for their previously undocumented keel‐garboard sewing technique and extensive use of bitumen coatings.

中国喀斯特植被分类系统

open access: yes, 2021
我国喀斯特地貌分布广泛,是全球喀斯特集中分布区面积最大且岩溶发育最强烈的典型区域。喀斯特植被物种组成独特,生物多样性丰富,群落结构复杂,植被类型极其丰富。该文对已发表的喀斯特植被类型和近期的调查资料进行系统整理,依据《中国植被志》的分类原则,在群系尺度上编制了中国喀斯特植被分类系统,包括3个植被型组、13个植被型和554个群系。探讨了喀斯特植被的分类系统与原有分类系统的衔接,并依据相关资料,对喀斯特生境专性群系进行了识别和判定,以期为喀斯特区域的石漠化治理 ...

漓江流域喀斯特森林土壤碳氮磷储量分布特征及其影响因素

open access: yesShuitu Baochi Xuebao, 2023
以探明漓江流域喀斯特森林土壤的碳氮磷储量分布为目的,为保护漓江流域脆弱的喀斯特生态系统提供理论依据。在漓江上中下游各流域段的典型喀斯特森林共设置20 m×20 m的15块天然林样方,对森林植被进行每木检尺调查,采用五点采集法采集0-20,20-40 cm土层土壤,分析土壤碳氮磷储量空间分布情况及驱动因子作用途径,量化各类生物和非生物因子对区域喀斯特森林土壤养分储量分布格局形成的作用贡献。结果表明:(1)漓江流域喀斯特森林土壤碳氮磷储量平均分布表现为上游>下游>中游,在漓江流域喀斯特森林土壤中碳、氮 ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

贵州茂兰喀斯特地区隐纹花松鼠秋季食性分析

open access: yes, 2022
隐纹花松鼠(Tamiops swinhoei)广布于我国南方各省且十分常见,但对其食性与生态研究却罕有报道,为进一步开展其觅食生态学研究,通过高通量测序技术测定贵州荔波茂兰喀斯特地区的隐纹花松鼠个体样本的胃容物。结果表明:从茂兰喀斯特地区的隐纹花松鼠胃容物中鉴定出植物7门73科109属,动物8门82科120属。其中,植物主要包括壳斗科(Fagaceae)、樟科(Lauraceae)、平藓科(Neckeraceae)、山茱萸科(Cornaceae)、胡桃科(Juglandaceae)和毛茛科 ...

Habitat Fragmentation in Urbanized Landscapes Favors Bird Species With Darker Plumage

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Using long‐term breeding bird survey data from 30 remnant woodlot patches within a rapidly urbanizing landscape in southwest China, we demonstrate that species with darker plumage are more likely to persist in highly fragmented habitats. The pattern is slightly more pronounced in males than in females.

Divergences in Leaf Economic Traits Among Five Congeneric Tree Species in a Subtropical Forest

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
Knowledge of how congeneric species co‐occur in a community differ in leaf economic traits, will advance the understandings of factors that contribute to the coexistence of closely related species in sympatry, especially in the karst forests of southwestern China that are generally rich in biodiversities. Here, we addressed this question and found that

Feedback on Escape Behavior of Birds Under Different Hunger Pressure

open access: yesEcology and Evolution, Volume 15, Issue 1, January 2025.
The balance between risk and benefit for birds in the face of external stress is highly significant. Our research has revealed that birds with heightened hunger pressure were more inclined to undertake greater risks when confronted with external stress, consequently increasing their foraging opportunities. ABSTRACT The risk of predation has always been
