    In this study, the bryophyte flora of Ermenek Valley (Karaman, Mersin) was investigated. In a total 163 taxa belonging to 27 families and 64 genera were determined by identifying the bryophyte specimens collected from 33 stations at different habitats and different vegetation periods between the years 2019 and 2020. Marchantiophyta, 10 taxa belonging to 8 families and 10 genera, Bryophyta, 153 taxa belonging to 19 families and 54 genera are represented. Among them, 39 taxa are new records for C12 grid square and, also Fissidens gymnandrus is recorded for the second time from Turkey. While Pottiaceae (44 taxa) and Brachytheciaceae (26 taxa) two largest families in the study area, Ptychostomum (11 taxa), Syntrichia and Grimmia (10 taxa) are the most species rich genera. Taxa in the floristic list, along with ecological characteristics and life forms were given.Bu ├žal─▒┼čmada, Ermenek VadisiÔÇÖnin (Karaman, Mersin) briyofit floras─▒ ara┼čt─▒r─▒lm─▒┼čt─▒r. 2019 ve 2020 y─▒llar─▒ aras─▒nda vejetasyonun farkl─▒ d├Ânemlerinde 33 istasyonun farkl─▒ habitatlar─▒ndan toplanan briyofit ├Ârnekleri te┼čhis edilerek 27 familya ve 64 cinse ait toplam 163 takson tespit edilmi┼čtir.

    The Isatis species has antibacterial, anticancer and antiviral properties and these important endemic plants grow widely in various parts of Anatolian-Turkey. In the present study, the antioxidant activities of Isatis floribunda Boiss. ex Bornm. flower and root extracts were determined with total antioxidant activity, free radical scavenging activity, ferric ion reducing power, and cupric ion reducing antioxidant capacity assay. The total phenolic compounds and flavonoids were also examined for the extracts. The antimicrobial activities of the extracts were investigated by using the disc diffusion and microdilution-broth methods against human and fish pathogen microorganisms. The phenolic composition of I. floribunda root methanolic extract was analyzed by high performance liquid chromatography (HPLC). The major component in the extract was cholorogenic acid (1980.20 ╬╝g/g). The cytotoxic effect of the methanolic root extract was also tested on human breast cell (MCF12A). The results showed that I. floribunda could be used as a natural source in the food and feed industry and clinical and food chemistry, and that the antimicrobial agents could be used against human and fish pathogens

    Karaman Erkul, Seher (Aksaray, Yazar)A taxonomic revision of the genus Oxytropis DC. (Leguminosae) in Turkey is presented. According to the recent literature, the genus had 13 taxa in Turkey; however, at the end of our studies the number was reduced to 11. It was determined that Oxytropis engizekensis Duman & Vural is a synonym of O. persica Boiss., and O. fominii Grossh. is a synonym of O. argyroleuca Bornm. Red List categories of the taxa were re-evaluated according to our results based on IUCN Red List categories. The Red List categories of O. pallasii Pers. and O. pilosa (L.) DC., which are ascribed as DD in the Red Data Book of Turkish Plants, were collected and defined in new threat categories after this study. In addition, phytogeographical areas for O. pallasii, O. pilosa, O. albana Steven, and O. lazica Boiss. are suggested here
