  1. 21. Examining the Link between Temperature and Flight Phenology in Hoverflies (Diptera: Syrphidae) Using Swedish Citizen Science Data

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Malin Magnusson Rundqvist; [2021]
    Keywords : climate change; hoverfly; phenology; pollinator; Sweden; Syrphidae;

    Abstract : Global warming is causing a general trend of rising temperatures worldwide. Simultaneously there is also a decline in populations of pollinators all over the world. Therefore, it is important to examine the effect warming temperatures might have on different pollinator species. READ MORE

    Abstract : Efterfrågan på pollinerade produkter från jordbruket ökar i takt med jordens befolkning. Samtidigt hotas pollinatörers existens av mänsklig omvandling av deras livsmiljöer och ett varmare klimat. READ MORE

  4. 23. Pollineringsplaner : ett nytt verktyg i kampen för biologisk mångfald?

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Keywords : pollinering; pollineringsplan; biologisk mångfald; ekosystemtjänst; planering; grönplan; GIS; ekologi; landskapsekologi;

    Abstract : Minskningar i pollinatörspopulationer är något som har observerats såväl globalt som nationellt. Detta innebär dels ett hot mot den biologiska mångfalden och dels en ekonomisk risk då många kommersiella grödor till varierande grad är beroende av pollinering. READ MORE

  5. 24. Insect pollination of faba beans, Vicia faba : the abundance and foraging behaviour of different pollinators and their effect on crop yield

    University essay from SLU/Dept. of Ecology

    Author : Ylva Johansson; [2020]
    Keywords : honeybee; Apis mellifera; bumblebees; B. pascuorum; B. hortorum; B. lucorum; B. terrestris; B. ruderatus; B. cryptarum; B. distinguendus; B. lapidarius;

    Abstract : Faba beans, Vicia faba is known as a self-pollinating crop, however significant yield increases have been found in plants visited by honeybees and bumblebees. The bees either make positive visits, entering the flower and transferring pollen between different flowers resulting in cross-pollination, or negative visits, piercing the flower to “steal” nectar or collect nectar from extrafloral nectaries.

  6. 25. 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
