  1. 1. Effect of suspended sediment on embryos and larvae of the cold‐water coral Lophelia pertusa

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Charlie Havsblad; [2022-09-13]
    Keywords : Lophelia pertusa; Desmophyllum pertusum; suspended sediment; embryo; larvae;

    Abstract : The cold-water coral Lophelia pertusa (syn. Desmophyllum pertusum) provides importanthabitats in deep-sea ecosystems, allowing for a biodiversity similar to that of tropical coral reefs. READ MORE

  3. 2. The effect of gut microbiota and insecticide resistance on host plant preferences and voracity of the cotton fly, Spodoptera littoralis

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

    Author : Vaida Dzemedzionaite; [2021]
    Keywords : Insecticide resistance; gut microbiota; insect pest; host plant preference; sustainable agriculture;

    Abstract : To counteract pesticide resistance development, it is crucial to understand why and when it evolves. Additionally, to inform the farmers about this term and provide advices on efficient pest management strategies to prevent pesticide resistance. READ MORE

  4. 3. Friends with benefits? - Does gut microbiota of Spodoptera littoralis affect insecticide resistance and are there any costs of insecticide resistance development?

    University essay from SLU/Dept. of Plant Protection Biology

    Author : Sarah Heithausen; [2021]
    Keywords : insecticide resistance development; gut microbiota; gut symbiont-mediated resistance; trade-off effects; fitness costs; symbiosis; survival; life-history traits; fecundity;

    Abstract : The insect gut microbiota has many important functions for insects such as detoxification of host plant toxins. Recently there has been a growing interest on the effect of insect gut microbiota on insecticide resistance development. Insecticide resistance is a growing concern for food security and sustainable agriculture. READ MORE

  5. 4. Valorisation of organic waste : effect of the feeding regime on process parameters in a continuous black soldier fly larvae composting system

    University essay from SLU/Dept. of Energy and Technology

    Author : Bram Dortmans; [2015]
    Keywords : organic waste management; animal feed; waste-to-biomass conversion rate; larval survival rate; waste reduction compost maturity;

    Abstract : Municipal solid waste- and especially organic solid waste management has be- come a major challenge in both developing and developed countries and is often related to the spread of diseases. At the same time, an increase in the demand for animal feed protein causes disturbances in (marine) ecosystems and nutrient recy- cling in soils is unsatisfactory in many places. READ MORE

  6. 5. Local adaptation of larval life history in the moor frog Rana arvalis across a landscape mosaic

    University essay from Institutionen för biologisk grundutbildning; Populationsbiologi och naturvårdsbiologi

    Author : Monique Lustenhouwer; [2012]
    Keywords : rana arvalis; moor frog; growth rate; local adaptation; life history; landscape mosaic; predation;

    Abstract : Growth rate is an important life history trait, which impacts fitness indirectly through its effect on the age and size at maturity, as well as directly through costs associated with accelerated growth such as increased predation risk. Genetic variation and plasticity in growth are widespread in nature, and local adaptation of growth rate may evolve due to divergent selection in different environments, for example related to predation risk, temperature or time constraints.
