“…Still, it has limitations because it only gives a picture of the environment at the sampling time (Zinsou et al 2016). The physicochemical components of water can play a pivotal role in the biology of a species and the structure and dynamics of the entire biocenosis (Thakur et al 2013;Enkhnasan and Boldgiv 2020). Therefore, it is necessary to understand the requirements of the living being in terms of temperature, salinity, transparency, dissolved oxygen, and different xenobiotics present in the environment as they intervene essentially as explanatory factors of the biological conditions.…”

“…Therefore, it is necessary to understand the requirements of the living being in terms of temperature, salinity, transparency, dissolved oxygen, and different xenobiotics present in the environment as they intervene essentially as explanatory factors of the biological conditions. The influence of the environment on species diversity is significant (Enkhnasan and Boldgiv 2020). According to Loucif et al (2020), the lake studied is currently in eutrophication.…”

Abstract. Mounira H, Fatiha BS, Noureddine S. 2023. Impact of physicochemical parameters of water on the biodiversity of the invertebrate fauna from Echatt Lake (Northeast Algeria). Biodiversitas 24: 258-268. Algeria is a case study of biodiversity ignorance. To date, there are neither complete inventories for any taxa nor atlas across the country! Yet, Algeria is of great importance for global biodiversity. The coastal area of Algeria is part of the global biodiversity hotspot which is the Mediterranean perimeter and has several regional red spots of biodiversity. Biodiversity provides raw material resources necessary for living beings' survival and maintaining atmospheric quality, climate regulation, water quality, and soil fertility. In addition, macrobenthic fauna is an important provider of aquatic ecosystems. The present study aimed to determine the biodiversity of the invertebrate community from Echatt Lake (Northeast Algeria) located in a protected area classified by Ramsar in 1983, and to evaluate the impact of anthropogenic activities using water physicochemical parameters on their structure and function. Samples were collected monthly over one year (January 2019-December 2019) at four selected stations, and 2,861 specimens were collected. The identified species (16 species) belong to 9 families: Naucoridae, Hydrophilidae, Notonectidae, Pleidae, Corexidae, Eylaidae, Pionidae, Daphniidae, and Copepoda. Seven physicochemical parameters (temperature, hydrogen potential, electrical conductivity, hydrometric title, alkalimetric title, complete alkalimetric titer, and turbidity) of the water were also determined in each station to evaluate their influence on the abundance and distribution of the invertebrate fauna. The pH and the apparent turbidity influence the invertebrate fauna, while the richness was relatively low at stations 2 and 4, located near anthropogenic sources of pollution. The data obtained permitted us to evaluate the possible impact of anthropogenic activities on the biodiversity of invertebrates.
