1. 1. Pollinator communities on a landscape complexity gradient in southern Sweden

   University essay from SLU/Dept. of Ecology

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

   Abstract : 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. READ MORE

3. 2. POLLINATION ECOLOGY OF PEDICULARIS SCEPTRUM-CAROLINUM : An investigation on flower visits in northern Sweden

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

   Author : Johan Närvä; [2022]
   Keywords : Pedicularis sceptrum-carolinum; Pollination; Pollination ecology; Pollinators; Bumblebees.;

   Abstract : Pedicularis sceptrum-carolinum is threatened in much of its geographic range. As it reproduces vegetatively only to a limited extent, the species relies heavily on pollinators for reproduction. One aspect often overlooked in restoration efforts is the pollination ecology of flowering plants and their pollinators. READ MORE

4. 3. Eternal sunshine on the flower-spotted ground : Investigating diel rhythms during midnight sun on high-Arctic pollinators

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

   Author : Emma Limosa Djurberg; [2021]
   Keywords : High Arctic; Svalbard; Spitsbergen; insects; diel rythms; midnight sun; adaptation; foraging;

   Abstract : With over 600 articles about terrestrial invertebrates in Svalbard we still lack basic knowledge about pollinator-plant interactions in this part of the high-Arctic. It has never before been investigated how the activity of pollinators varies over a 24-hour timeframe in the high Arctic. READ MORE

5. 4. Intercropping oats with annual clovers : effects on yields and aspects of biodiversity

   University essay from SLU/Dept. of Ecology

   Author : Anna Douhan Sundahl; [2021]
   Keywords : intercropping; cover cropping; pollinators; natural predators; weeds; clover; oats;

   Abstract : The use of fertilizers, pesticides and herbicides has contributed to greatly increase the crop yields per hectare. Humanity has become reliant on artificial inputs overshadowing usage of resources from ecosystem services that we continue to weaken further, by using agricultural practises decreasing landscape and species diversity.

6. 5. Flower-visiting insects benefit from forest in the surrounding landscape

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

   Author : Emilia Sundell; [2021]
   Keywords : Apoidea; clear-cut; Coleoptera; forest; Hymenoptera; landscape composition; Lepidoptera; Syrphoidea;

   Abstract : Habitat loss and fragmentation due to agricultural practices are causing worrying declines in insect diversity and biomass. Agricultural intensification, among other things, have led to a decline in semi-natural grasslands. Forest in the surrounding landscape can have a positive effect on species abundance in grasslands.
