Abstract

The composition and spatial distribution of macroinvertebrates in the Damsa reservoir have been analysed. Also, reservoir water was evaluated with water quality index (WQI). Damsa reservoir is significant for both biodiversity and recreation in the region. Except for the winter season, the lake water is of good quality for WQI. There is pollution in the lake in terms of phosphorus, especially for winter. In terms of phosphate, all of the stations are mezotrophic for the OECD; however, Stations 4 and 5 are eutrophic for the Türkiye Surface Water Quality Management Regulation (the others are mezotrophic). Community variation and status of benthic macroinvertebrate were evaluated with Ecological Status Class Assessment Tools (ESCATs) indices which have been widely used in the literature. In the present study, 1062 individual benthic macroinvertebrates from 11 orders and 17 families were collected. A total of 46 macroinvertebrates taxa were identified. The first three dominant groups are Oligochaeta (42.66%), Hemiptera (Micronecta scholtzi, 23.07%) and Chironomidae (19.67%).

用小型水库(土耳其达姆萨)中的大型无脊椎动物和水质指数评估水质
分析了达姆萨水库中大型无脊椎动物的组成和空间分布。此外,还用水质指数(WQI)对水库水进行了评估。达姆萨水库对该地区的生物多样性和娱乐活动都具有重要意义。除冬季外,湖水水质指数(WQI)良好。湖中存在磷污染,尤其是在冬季。就磷酸盐而言,根据经合组织(OECD)标准,所有监测站均为弱营养型;但根据土耳其地表水水质管理条例,4 号和 5 号监测站为富营养型(其他监测站均为弱营养型)。底栖大型无脊椎动物的群落变化和状态采用文献中广泛使用的生态状态等级评估工具(ESCATs)指数进行评估。本研究收集了 11 目 17 科 1062 个个体的底栖大型无脊椎动物。共鉴定出 46 个大型无脊椎动物类群。前三个主要类群分别是偶蹄目(42.66%)、半翅目(Micronecta scholtzi,23.07%)和摇蚊科(Chironomidae,19.67%)。

期刊介绍: Ecohydrology is an international journal publishing original scientific and review papers that aim to improve understanding of processes at the interface between ecology and hydrology and associated applications related to environmental management. Ecohydrology seeks to increase interdisciplinary insights by placing particular emphasis on interactions and associated feedbacks in both space and time between ecological systems and the hydrological cycle. Research contributions are solicited from disciplines focusing on the physical, ecological, biological, biogeochemical, geomorphological, drainage basin, mathematical and methodological aspects of ecohydrology. Research in both terrestrial and aquatic systems is of interest provided it explicitly links ecological systems and the hydrologic cycle; research such as aquatic ecological, channel engineering, or ecological or hydrological modelling is less appropriate for the journal unless it specifically addresses the criteria above. Manuscripts describing individual case studies are of interest in cases where broader insights are discussed beyond site- and species-specific results.
