摘要

对地中海浅海湖泊(土耳其伊兹密尔的Golcuk湖)的大型底栖无脊椎动物群落进行了研究，以(a)描述底栖动物群落的年际和空间变异，(b)将群落可能的变化与环境条件联系起来，(c)评价湖泊生态状况对群落指数的响应。在2年期间(2008年6月至2010年3月)，在6个地点对底栖生物群落进行了季节性采样。此外，在同一时期监测了每个站点的低代谢水质变量。戈尔库克湖底栖动物十分有限，仅有4个类群16种。主要底栖动物种类为hammonipotamothrix，占底栖动物总数的72%以上。深度、溶解氧、pH、电导率、透明度和水温是影响群落指数的主要环境因子。戈尔丘克湖底栖生物群落受到人为干扰的影响，其组成向更宽容的分类群转变，也反映了湖泊富营养化到富营养化的特征

Assessment of a Shallow Montane Lentic Ecosystem (Lake Golcuk, Izmir, Turkey) Using Benthic Community Diversity

The macrobenthic invertebrate community of a shallow Mediterranean lake (Lake Golcuk, Izmir, Turkey) was studied in order to (a) describe the intra-annual and spatial variability in benthic communities, (b) relate possible community changes to environmental conditions and (c) evaluate the responses of the lake’s ecological status on community indices. The benthic assemblage was sampled seasonally at six sites during a period of 2 years (June 2008-March 2010). Additionally, hypolimnetic water quality variables were monitored over the same period at each site. The benthic fauna of Lake Golcuk was found to be very limited with 16 species belonging to four taxonomic groups. Potamothrix hammoniensis was the dominant benthic species and represented more than 72% of the total benthic fauna. Depth, dissolved oxygen, pH, conductivity, transparency, and water temperature seemed to be the main environmental factors affecting community indices. Benthic communities are affected by human disturbances in Lake Golcuk shifting their composition to more tolerant taxa, reflecting also the eutrophic to hypertophic character of the lake

期刊介绍： Cessation. Ekoloji is an international journal that focuses on papers that report results from original research on all disciplines engaged in the field of environmental research. We welcome articles that cover the entire spectrum of environmental problems and environmental pollutants, whether chemical, biological or physical. Its coverage extends to all environmentally related issues: air and water pollution, solid waste, noise, recycling, natural resources, ecology and environmental protection. It includes articles on basic and applied environmental pollution research, including environmental engineering and environmental health. All types of pollution are covered, including atmospheric pollutants, detergents, fertilizers, industrial effluents, metals, mining wastes, oil, pesticides, plastics, radioactive materials and sewage. It also includes research papers on ecological and environmental issues such as climate change, biodiversity. The primary criteria for publication are scientific quality and ecological/environmental significance. The journal will be read and contributed to by biologists, applied ecologists, environmental scientists, natural resource specialists, environmental engineers, environmental health specialists, agro-ecologists, veterinaries, agricultural engineers, landscape planners and designers. The journal welcomes full "research papers" and short "research notes", only in the English language.
