1. 6. Modelling the effects of substituting pollinators in decline

   Kandidat-uppsats, Lunds universitet/Matematik LTH

   Författare :Axel Eriksson; [2023]
   Nyckelord :pollinators; plants; mutualism; competition; equilibrium populations; Mathematics and Statistics;

   Sammanfattning : While pollination is essential for many plant species and ecosystem functions, pollinator populations worldwide are declining. This decline is largely due to abiotic changes in the environment: climate change and other anthropogenic impacts, such as pesticides and land use change. LÄS MER

3. 7. Ekologisk funktionalitet i Malmö : En jämförande undersökning av biodiversitet i Varvsparken & Strandparken

   Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

   Författare :Emma Flokén; Sofia Maria Cato; [2023]
   Nyckelord :Urban biodiversity; ecological functionality; trees; birds; vegetation; Urban biodiversitet; ekologisk funktionalitet; inventering; fåglar; träd; vegetation;

   Sammanfattning : Ett stort hot mot biologisk mångfald är urbaniseringen, då utbyggnad av städer leder till attplatser som tidigare utgjort viktiga habitat ersätts av hårdgjorda ytor, byggnader och mänskligaktivitet. Det finns ett nytt tankesätt inom stadsplanering, nämligen förtätning. LÄS MER

4. 8. Pollinator communities on a landscape complexity gradient in southern Sweden

   Magister-uppsats, SLU/Dept. of Ecology

   Författare :Hanna Olsson; [2023]
   Nyckelord :pollinator; bumblebee; rough pasture; semi-natural pasture; unimproved grazing; landscape complexity;

   Sammanfattning : Investigating how pollinator populations are affected by land use changes is crucial for predicting their persistence in the landscape and thereby the persistence of the significant service they provide to crop production. Pollinator populations are subjected to multiple threats, particularly overall intensification of cropping systems and landscape simplification. LÄS MER

5. 9. Competition between managed honeybees and wild bumblebees - Quantifying dietary overlap in semi-natural grasslands

   Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Författare :Emma Rosberg; [2023]
   Nyckelord :Earth and Environmental Sciences;

   Sammanfattning : The decline of bees, such as bumblebees, over the last decades raises concerns as they are key pollinators in both agricultural and natural ecosystems. One proposed cause for the decline of wild bees is competition for food resources with managed honeybees. LÄS MER

7. 10. ​Malmö municipality employees’ relation with nature in the context of flowering plants, pollinators and ecosystem services : An investigation of goals and conflicts within municipality work

   Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

   Författare :Andrea Håkansson; Hanna Takkinen; [2023]
   Nyckelord :;

   Sammanfattning : Cities are facing a loss of green areas that are important for reasons such as the support of pollinators. Pollination of flowering plants is a part of the concept of ecosystem services and is beneficial for humans in providing food security and the upkeep of urban ecosystems. LÄS MER
