  1. 1. Fishy behavior persistent effects of early-life exposure to 17α-ethinylestradiol

    University dissertation from Örebro : Örebro university

    Author : Kristina Volkova; Örebro universitet.; Södertörns högskola.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Endocrine disruptors; anxiety; stress behavior; transgenerational effects; 17α-ethinylestradiol; developmental exposure; social behavior; fish;

    Abstract : The synthetic estrogen 17α-ethinylestradiol (EE2) is an endocrine disrupting chemical (EDC) of concern due to its persistent nature and widespread presence in the aquatic environment. In mammals, effects of developmental EDC exposure on reproduction and behavior not only persist to adulthood after discontinued exposure, but are also inherited by several consecutive unexposed generations.

  2. 2. Pheromonal Mediated Behaviour and Endocrine Responses in Salmonids The impact of Cypermethrin, Copper, and Glyphosate

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Abstract : The effects of cypermethrin, copper and glyphosate on the endocrine system and subsequent response to female pheromones were investigated in mature male brown trout (Salmo trutta) parr.  Responses measured were the amount of strippable milt, blood plasma levels of both an androgen (11-ketotestosterone (11-KT)) and a progestin (17α,20β-dihydroxy-4-pregnen-3-one (17,20b-P)), and behavioural changes.

  3. 3. Endocrine disruption in fish Effects of 17α-ethinylestradiol exposure on non-reproductive behavior, fertility and brain and testis transcriptome

    University dissertation from Huddinge : Södertörns högskola

    Author : Tove Porseryd; Södertörns högskola.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 17α-ethinylestradiol; endocrine disrupting chemical; fish; behavior; fertility; transcriptome; RNA sequencing; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : Aquatic environments are the end recipient for most anthropogenic chemical pollutants. One common chemical pollutant found in the aquatic environment is 17α-ethinylestradiol (EE2), a synthetic estrogen used in contraceptive pills. READ MORE

  4. 4. Aquatic organisms on the pill - effects on different organizational levels

    University dissertation from Department of Biology, Lund University

    Author : Per Hallgren; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; EDC; EE2; 17α-ethinylestradiol; fish; zooplankton; gastropods; population growth rates; direct and indirect effects; somatic growth; invertebrates;

    Abstract : Communities are composed of organisms that interact with each other and with the non-biological environment. There are also anthropogenic pollutants in the environment that also interact with the organisms. READ MORE

  5. 5. Hitting the mark studies of alterations in behaviour and fertility in ethinyl estradiol-exposed zebrafish and search related biomarkers

    University dissertation from Örebro : Örebro university

    Author : Nasim Reyhanian Caspillo; Örebro universitet.; Södertörns högskola.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Endocrine disrupting compounds; 17α-ethinylestradiol; fertility; anxiety; behaviour; zebrafish; biomarkers; stress;

    Abstract : In this thesis, we have analysed the effects of EE2 on non-reproductive behaviours and fertility. We have showed that two doses of EE2 in male adult short-term exposures evokes opposite behaviours in the novel tank test. READ MORE
