  1. 1. System ecology of legumes mixes in ley production : impact on pollinating insects and further implications for production in northern Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Philippe Simon; [2023]
    Keywords : Ley production; Nitrogen fixation; Pollination ecology;

    Abstract : The population and diversity of pollinating insects in Europe are declining, partly due to lossof habitat. In agricultural landscapes, farming practices with more intensified land use haveincreased. In Swedish agricultural habitats, most ley production is dominated by grass and red clover (Trifolium pratense). READ MORE

  3. 2. Differences in plant trait distribution in semi-natural grassland habitats of Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Viivi Vepsäläinen; [2020]
    Keywords : Plant traits; semi-natural grassland habitats; landscape openness; landscape ecology;

    Abstract : Habitat type has been suggested to be a major factor contributing to differencesin plant trait distribution of grassland habitats. Land use changes in agricultural landscapes have affected the available habitats and the dispersal ability of plants, which may effect plant trait diversity of agricultural landscapes. READ MORE

  4. 3. Importance of bumble bee community evenness for crop pollination : a simulation analysis of Swedish red clover seed production

    University essay from SLU/Dept. of Ecology

    Author : Vivek Babu; [2018]
    Keywords : bumble bee; Bombus; community; evenness; biodiversity-ecosystem function; diversity-stability; diversity-productivity; overyielding; productivity; stability; biodiversity; selection effect; species asynchrony; portfolio effect;

    Abstract : The red clover seed production systems are dependent on pollinators for increase in red clover seed yield and its stability. When compared to domesticated honey bees, the wild bumble bees are highly efficient in pollinating the red clover crop due to its relatively longer tongue length. Longer dependence on single pollinator species i.e. READ MORE

  5. 4. Homogenization of tomato and apricot juice concentrate and a sensory analysis of its effect

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Ulrich Hermann Koppmaier; [2018]
    Keywords : Homogenization; Fruit juice; Fruit juice concentrate; Tomato; Apricot; sensory analysis; food engineering; livsmedelsteknik; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : Juice homogenization is mostly done to create smaller fiber particles, which reduces the sedimentation velocity to a lower level. So far, fruit juice concentrate is diluted to juice before it is homogenized. READ MORE

  6. 5. Biodiversitet som förebyggande åtgärd : IPM-strategier för grönsaksodling på friland

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

    Author : Yenny Leijon; [2017]
    Keywords : IPM; biodiversitet; hortikultur; nyttodjur; grönsaker; habitatmanipulering; landskapsdiversitet; ekosystemtjänster;

    Abstract : Biodiversiteten i odlingslandskapen är på stadig nedgång, bland orsakerna till detta finns användandet av kemiska växtskyddsmedel och årlig jordbearbetning. Att biodiversiteten minskar är ett hot mot vår framtida odling i dessa landskap då vi är beroende av mångfalden för ett uthålligt produktionssystem. READ MORE
