  1. 6. Response of Daphnia magna from Natural Populations to Ultraviolet Radiation

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Luo Zheng; [2018]
    Keywords : Biology and Life Sciences;

    Abstract : Diel vertical migration (DVM) is performed by various zooplankton taxa. The general movement pattern of DVM has been well studied while the possible clonal differences of this movement largely remain unknown. My master thesis focus on investigating the effects of environmental stressors on Daphnia magna strains isolated from natural populations. READ MORE

  3. 7. (Toxic) effects induced by synthetic and natural microparticles on Daphnia magna : Investigating particles and mixtures

    University essay from Stockholms universitet/Institutionen för miljövetenskap och analytisk kemi

    Author : Markus Hermann; [2018]
    Keywords : Microplastic mixtures; natural particles; Daphnia magna; effect studies; risk assessment;

    Abstract : With increasing global plastics production, the amounts of fragmenting, microscopic plastic debris (microplastics, MPs) are anticipated to rise in aquatic environments. The ecological consequences of this pollution are currently unknown. READ MORE

  4. 8. Once upon a time in Germania Magna. The relation between terra sigillata and the historical events in the northwestern and northeastern Europe (1-400 CE)

    University essay from Lunds universitet/Arkeologi

  5. 9. A comparison between the effects of polylactic acid and polystyrene microplastics on Daphnia magna

    University essay from Stockholms universitet/Institutionen för miljövetenskap och analytisk kemi

    Author : Mikaela Puranen Vasilakis; [2017]
    Keywords : Microplastics; daphnia magna; bioplastics; feeding rate; reproduction; Mikroplast; daphnia magna; bioplast; födoupptag; reproduktion;

    Abstract : The effects of microplastics on zooplankton are an increasing environmental concern. Both primary microplastics that are produced as constituents of cosmetic products, as well as secondary microplastics that are formed by degradation of larger plastic debris, are ubiquitous in aquatic environments.

  6. 10. Combination of nanoparticles from polystyrene and the hormone 17alpha-ethinylestradiol (EE2) in water.

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Emma Nilsson; [2017]
    Keywords : water; nanoparticles; hormons; Plastic; Earth and Environmental Sciences;

    Abstract : Plastic materials and synthetic hormones are found in aquatic environments globally. Plastic in water can degrade to nanoparticles (NP) with special characteristics, in the environment nanoparticles and hormones have a proven effect on wildlife. READ MORE
