摘要:

干旱、半干旱区人工固沙植被建设及管理驱动植被和土壤环境变化,强烈影响荒漠节肢动物多样性及其生态功能。然而,我们对流动沙丘转变为梭梭(Haloxylon ammodendron)林对地表节肢动物多样性的认识还很有限。以栽植梭梭和未栽植梭梭的流动沙丘为研究对象,运用方差分析和多变量分析等方法定量研究了流动沙丘建植梭梭人工林对地表节肢动物多样性的影响。结果表明:流动沙丘转变为梭梭林强烈影响地表节肢动物群落组成及多样性,这种影响还随着季节变化而变。在群落水平,梭梭人工林建植显著提高了5月和9月荒漠地表节肢动物数量和物种丰富度,还提高了9月地表节肢动物多样性。在营养功能群水平,梭梭人工林建植显著提高了5月和9月杂食性地表节肢动物数量和物种丰富度,仅在5月显著提高了捕食性地表节肢动物的数量和物种丰富度。在种水平,梭梭人工林建植显著提高了5月和9月戈壁琵甲(Blaps gobiensis)和东鳖甲属(Anatolica sp.)1种的捕获数量,但显著降低了尖尾东鳖甲(Anatolica mucronata)的捕获数量;克氏扁漠甲(Sternotrigon kraatzi)和谢氏宽漠王(Mantichorula semenowi)在梭梭人工林5月的数量显著提高,艾箭蚁(Cataglyphis aenescens)的数量则在9月显著提高。此外,研究还发现这些节肢动物种对流动沙丘或梭梭人工林生境有一定的指示性。总之,流动沙丘地表节肢动物对梭梭人工林建植的响应随着取食类型和季节变化而变,进而改变地表节肢动物群落结构及其功能。

Abstract:

Artificial sand-fixing vegetation establishment and management in arid and semi-arid regions drive significant changes in vegetation and soil environments, profoundly influencing desert arthropod diversity and ecological functions. However, our understanding of how the conversion of mobile sand dunes to Haloxylon ammodendron plantations affects ground arthropod diversity remains limited. This study compared arthropod communities between Haloxylon-planted and non-planted mobile dunes using ANOVA and multivariate analyses. Our results demonstrate that H. ammodendron afforestation significantly altered the community composition and trophic structure of ground arthropods, with these effects exhibiting distinct seasonal variations. At community level, the establishment of H. ammodendron plantations significantly increased arthropod abundance and species richness in May and September. Moreover, diversity indices of ground arthropods showed significant improvement only in September. At trophic group level, omnivores exhibited significant increased abundance and richness in both sampling periods, while predators showed significant increases only in May. At species level, Blaps gobiensis and Anatolica sp. showed positive responded patterns both sampling periods, and an opposite pattern on A. mucronata. Furthermore, Sternotrigon kraatzi and Mantichorula semenowi showed positive responded patterns only in May, and Cataglyphis aenescens showed a positive responded patterns only in September. In addition, several species demonstrated significant habitat indicator values for mobile sandy dunes or H. ammodendron plantations. Collectively, our findings demonstrate that young plantation in mobile sandy dunes induces taxon-specific and seasonally-dependent responses among ground arthropods, ultimately reshaping community structure and functional dynamics in this desert ecosystem.

Key words: mobile sandy dunes, Haloxylon ammodendron plantations, ground arthropod diversity, trophic structure, indicator species
