Effects of land use change on macroinvertebrate community composition in upper reaches of the Chehel-Chai chatchment, Iran
Urbanization of catchment regions is a major cause of freshwater ecosystem degradation worldwide. As catchments become more developed and river ecosystems become increasingly engulfed in various land use activities, there is a growing need to understand these impacts on freshwater ecosystems.

Urbanization of catchment regions is a major cause of freshwater ecosystem degradation worldwide. As catchments become more developed and river ecosystems become increasingly engulfed in various land use activities, there is a growing need to understand these impacts on freshwater ecosystems. Macroinvertebrate are extensively used as indicators of ecosystem health and have been an instrument tool in ecosystem monitoring and management. Five stations with different types of land use (reference station, forest, recreational, agricultural, urban area) of Chehel Chai River, Iran were sampled in 2018. A total of 2040 macroinvertebrate belonging to 6 orders from 12 families were identified. The highest abundance was related to the diversity of the Ephemeroptera (Batidae). According to the results, the abundance of macroinvertebrate was significantly different in the seasons and sampling stations. The maximum value of diversity indices was measured to the Shannon index (S1= 1.06, autumn), Simpson's Index (S1= 0.63, autumn), Margalef richness (S1= 0.9, spring) and Pielou's index (S3= 0.92, summer).
