Abstract

Abstract The aim of the research was to study the diversity of hoverflies (Syrphidae: Diptera) living in areas under the influence of heavy metal emissions (Cd, Zn and Pb). Although the area of the Olkusz Ore-bearing Region (OOR), where the research was partially conducted, belongs to the contaminated regions, where a relatively high species richness of Syrphids has been noted. During the research period, a total of 1,180 syrphids, belonging to 165 species were caught, which constitutes 39.76% of all the Polish Syrphidae fauna. These species represented all the trophic groups with the dominance of zoophagous species (48.48%); however, the most numerous (quantitatively abundant) were saprophagous. Among the collected syrphids, common and numerous species, such as: E. arbustorum (LINNAEUS, 1758), E. tenax (LINNAEUS, 1758), Episyrphus balteatus (DE GEER, 1776) and S. pipiens (LINNAEUS, 1758), as well as rare species such as Callicera aenea (FABRICIUS, 1777) (NT), Chalcosyrphus piger (FABRICIUS, 1794) (DD), Epistrophe ochrostoma (ZETTERSTEDT, 1849) (VU), Orthonevra geniculata (MEIGEN, 1830) (DD), Rhingia rostrata (LINNAEUS, 1758) (DD), Sphegina sibirica STACKELBERG, 1953 (LC) and Spilomyia diophthalma (LINNAEUS, 1758) (NT), were noted. Eleven of the collected species have been included in the Polish Red List of Endangered Species. Melangyna ericarum (COLLIN, 1946) is recorded as a new one among the Polish fauna. Numerous observations did not indicate that the area covered by the study was characterised by a significantly lower species diversity compared to other sites. In fact, the samples taken were usually characterised by a relatively high biodiversity. The obtained results may suggest that anthropogenic activities, including those leading to environmental pollution with heavy metals and to a strong transformation of natural habitats, do not completely destroy biodiversity, and in some cases leave space for nature to create habitats where even rare species of organisms such as Syrphidae can develop.

受重金属（Cd、Zn、Pb）污染地区的悬停蝇（夜蛾科：直翅目）

摘要本研究的目的是研究生活在重金属排放（Cd、Zn和Pb）影响下的地区的气垫蝇（夜蛾科：直翅目）的多样性。尽管部分进行研究的Olkusz含矿区（OOR）属于受污染地区，但已注意到该地区的Syrphids物种丰富度相对较高。在研究期间，共捕获了1180只共有165种的Syrpids，占波兰Syrphidae动物群的39.76%。这些物种代表了以浮游动物为主的所有营养类群（48.48%）；然而，数量最多（数量丰富）的是食腐动物。在收集到的同形目中，常见的和众多的物种，如：熊果木（LINNAEUS，1758）、金龟子（LINNAUEUS，1758，注意到膝原痣（MEIGEN，1830）（DD）、玫瑰鼻（LINNAEUS，1758）（DD。收集到的11种物种已被列入波兰濒危物种红色名录。在波兰动物群中，黑腹女蛛（Melangyna ericarum，COLLIN，1946）是一种新的动物。大量观察结果并没有表明，与其他地点相比，该研究覆盖的区域的物种多样性明显较低。事实上，采集的样本通常具有相对较高的生物多样性。所获得的结果可能表明，人类活动，包括那些导致重金属污染环境和自然栖息地发生强烈变化的活动，并没有完全破坏生物多样性，在某些情况下，为大自然创造栖息地留下空间，即使是像水貂科这样的稀有生物也可以在那里发展。

期刊介绍： Folia Horticulturae is an international, scientific journal published in English. It covers a broad research spectrum of aspects related to horticultural science that are of interest to a wide scientific community and have an impact on progress in both basic and applied research carried out with the use of horticultural crops and their products. The journal’s aim is to disseminate recent findings and serve as a forum for presenting views as well as for discussing important problems and prospects of modern horticulture, particularly in relation to sustainable production of high yield and quality of horticultural products, including their impact on human health.
