Floodplain forests represent the habitats sensitive to environmental and ecological changes. Assessing their impact on dynamics of weevil communities requires a detailed understanding of the environmental demands of each species. Therefore, we studied the epigean communities of weevils in eight similar habitats of floodplain forests during 2015–2016. The study material of Curculionoidea was obtained by pitfall trapping. We focused on a comparison of the occurrence of weevils in floodplain forests and their ecotones alongside three rivers, the Danube in Slovakia and the Tisa and Begej in Serbia. We investigated the dependence of weevil’s occurrence on plant diversity of vegetation layers, cover of vegetation layers, area and circumference of forest stands, age of forest stands, distance to the forest edge, thickness of litter layer, physical-chemical properties of soil and litter (conductivity, pH, N, P, C, H) and anthropogenic impact. Total epigeic activity of weevils showed a significant continual proportion with number of plant species in shrub vegetation layer and inverse proportion with relative content of H in soil and circuit of fragment in which we located the traps. Species richness was significantly positively related to the number of plant species in herb and negatively to stand canopy of tree vegetation layers, the area, circuit and age of forest fragment, depth of litter layer, and also to relative content of N and H in soil. Shannon diversity showed a significant continual proportion with the circuit of the fragment. Evenness was positively linked to the fragment area and circumference.

中欧洪泛区森林中象鼻虫(鞘翅目,Curculionoidea:Brentidae,Curculionidae)的土壤居住群落:与环境参数的比较相互作用

漫滩森林是对环境和生态变化敏感的栖息地。评估它们对象鼻虫群落动态的影响需要对每个物种的环境需求有详细的了解。因此,我们研究了2015-2016年洪泛平原森林的八个类似生境中的象鼻猩猩群落。Curculionoidea的研究材料是通过陷阱陷阱获得的。我们着重比较了泛滥的森林及其过渡带中的象鼻虫的发生情况,这三条河是斯洛伐克的多瑙河和塞尔维亚的蒂萨和贝杰伊这三个河流。我们调查了象鼻虫的发生对植被层植物多样性,植被层覆盖度,林分面积和周长,林分年龄,距林缘的距离,枯枝落叶层厚度,土壤和垃圾的物理化学特性(电导率,pH,N,P,C,H)和人为影响。象鼻虫的总表皮活动与灌木植被层中植物种类的数量具有显着的连续比例,而与土壤中H和相对含量的比例成反比,而我们所处的圈套地段则是碎片。物种丰富度与草本植物种类的数量呈显着正相关,与树木植被层的冠层,森林碎片的面积、,回和年龄,枯枝落叶层的深度以及土壤中氮和氢的相对含量呈显着正相关。 。香农多样性与片段的循环显示出显着的连续比例。均匀度与碎片面积和周长呈正相关。H)和人为影响。象鼻虫的总表皮活动与灌木植被层中植物种类的数量具有显着的连续比例,而与土壤中H和相对含量的比例成反比,而我们所处的圈套地段则是碎片。物种丰富度与草本植物种类的数量呈显着正相关,与树木植被层的冠层,森林碎片的面积、,回和年龄,枯枝落叶层的深度以及土壤中氮和氢的相对含量呈显着正相关。 。香农多样性与片段的循环显示出显着的连续比例。均匀度与碎片面积和周长呈正相关。H)和人为影响。象鼻虫的总表皮活动与灌木植被层中植物种类的数量具有显着的连续比例,而与土壤中H和相对含量的比例成反比,而我们所处的圈套地段则是碎片。物种丰富度与草本植物种类的数量呈显着正相关,与树木植被层的冠层,森林碎片的面积、,回和年龄,枯枝落叶层的深度以及土壤中氮和氢的相对含量呈显着正相关。 。香农多样性与片段的循环显示出显着的连续比例。均匀度与碎片面积和周长呈正相关。象鼻虫的总表皮活动与灌木植被层中植物种类的数量具有显着的连续比例,而与土壤中H和相对含量的比例成反比,而我们所处的圈套地段则是碎片。物种丰富度与草本植物种类的数量呈显着正相关,与树木植被层的冠层,森林碎片的面积、,回和年龄,枯枝落叶层的深度以及土壤中氮和氢的相对含量呈显着正相关。 。香农多样性与片段的循环显示出显着的连续比例。均匀度与碎片面积和周长呈正相关。象鼻虫的总表皮活动与灌木植被层中植物种类的数量具有显着的连续比例,而与土壤中H和相对含量的比例成反比,而我们所处的圈套地段则是碎片。物种丰富度与草本植物种类的数量呈显着正相关,与树木植被层的冠层,森林碎片的面积、,回和年龄,枯枝落叶层的深度以及土壤中氮和氢的相对含量呈显着正相关。 。香农多样性与片段的循环显示出显着的连续比例。均匀度与碎片面积和周长呈正相关。物种丰富度与草本植物种类的数量呈显着正相关,与树木植被层的冠层,森林碎片的面积、,回和年龄,枯枝落叶层的深度以及土壤中氮和氢的相对含量呈显着正相关。 。香农多样性与片段的循环显示出显着的连续比例。均匀度与碎片面积和周长呈正相关。物种丰富度与草本植物种类的数量呈显着正相关,与树木植被层的冠层,森林碎片的面积、,回和年龄,枯枝落叶层的深度以及土壤中氮和氢的相对含量呈显着正相关。 。香农多样性与片段的循环显示出显着的连续比例。均匀度与碎片面积和周长呈正相关。
