    ABSTRACT
    The contribution to the study of the biodiversity of Diptera associated with the cultivated olive tree took place over a year from December 2018 to November 2019, in two stations located in the west of Algeria. The aim of this present work is to learn about the biodiversity of Diptera associated with the olive tree cultivated in the Tiaret region. Sampling frequency was on the order of one outing per month using the yellow plates and barber jars to collect the specimens. We identified 1124 individuals or 46 species belonging to 29 families. The Sciaridae family is the most representative in Ain Guesma station with a relative abundance AR% of 23%. While in the station of Oued lili the Chirinominidae family is the most captured, at 18.52%. The two stations present a great diversity of species (H ’= 3.58 Ain Guesma, H’ = 3.65 in Oued Lili). The equity of the species identified in this study is greater than or equal to 0.76.

    Diatoms diversity in Oubeïra Lake, northeastern Algeria

    ABSTRACT
    Mediterranean wetlands are currently subjected to habitat loss and degradation derived from pollution, climate change, eutrophication and the occurrence of exotic species as the most important threats, affecting numerous taxonomic groups. Different tools are being used to assess water quality conditions in these environments, including physicochemical measurements and biological indicators (fish, invertebrates, and diatoms). We aim to study the diversity and ecology of the diatom assemblage inhabiting the RAMSAR site Oubeïra Lake in northeastern Algeria, contributing to the catalogue of diatoms recorded for Algeria. The identification of the morphological characters allowed us to make an inventory of 18 genera of diatoms belonging to 13 families of diatoms. Navicula and Cymbella resulted in the most abundant genera in the two studied stations during February, June, and August over two years (2017, 2018). The diatom community is structured, with a diversity index (H) equal to ~2.30.
