  1. 1. Biodiversity of aquatic invertebrates in urban ponds: effects of land use

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Roberta Hedberg; [2019]
    Keywords : ;

    Abstract : Urban ponds have the potential to hold large abundance and diversity of aquatic invertebrates, which could maintain an overall high biodiversity in the urban landscape. Little is known about how aquatic systems, such as ponds, are affected by the fast rate of urbanisation caused by an increasing human population together with the expansion of cities. READ MORE

  3. 2. Towards a sustainable pest management of the invasive bug Halyomorpha halys in Trentino province, Italy

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Damiano Moser; [2019]
    Keywords : Brown Marmorated Stink Bug; H. Halys; hemiptera; biotremology; Semi-Structured Interview; Thematic Analysis; invasive species; stakeholder perception;

    Abstract : Some invasive insects are agricultural pests, like the brown marmorated stinky bug (BMSB), an extremely phytophagous pentatomids. The lack of efficient low-impact control strategies makes this insect extremely dangerous for agricultural crops. In Italy, the first established populations of BMSB were found in 2012. READ MORE

  4. 3. Evaluating six crop mixes used for game fields in southwest Sweden : biomass production, fallow deer preference and species diversity

    University essay from SLU/Dept. of Ecology

    Author : Elin Grönberg; [2011]
    Keywords : arthropods ; biomass production; biomass consumption; crop mix; Dama dama; fallow deer; game field; species diversity index;

    Abstract : Game fields are one way to divert animals away from sensitive areas, create shelter and forage, and also to increase the biological diversity. In this study I investigated how the plant composition in six different crop mixes used for game fields affected the biomass production, biomass consumption and biological diversity at the Koberg estate in southwestern Sweden.
