1. Restaurering av grässandhedar genom aktiv markstörning - en jämförelse av florans kolonisation av plöjningar och sandblottor på Revingefältet utanför LundMaster-uppsats, Lunds universitet/Examensarbeten i biologi
Sammanfattning : The conservation value of sandy habitats for a flora and fauna adapted to open, light, dry, warm, and often nutrient-poor conditions, is well recognized. Today this environment is threatened by lack of disturbance, fragmentation and exploitation, acidification and increased levels of nitrogen and phosphorus. LÄS MER
- Master-uppsats, Lunds universitet/Examensarbeten i biologi
Sammanfattning : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.

3. The effects of the exploiters (non-pollinating insects) on mutualistic interactions between the plant and its pollinatorMaster-uppsats, Lunds universitet/Examensarbeten i biologi
Sammanfattning : Mutualistic interactions between, for example, plants and pollinators play a crucial role in maintaining the biodiversity of ecosystems, while non-pollinating insects (exploiters) that exploit plants are commonly thought to have destabilizing effects. The long-term, i.e. LÄS MER
4. “What’s the buzz with bilberries?” – Bilberry pollinator community structure and function in relation to forest type and habitat structureMaster-uppsats, Lunds universitet/Examensarbeten i biologi
Sammanfattning : Over the last century, Swedish forests have undergone rapid land-use change due to intensification of management practices for timber production and the introduction of monocultures, which have resulted in considerable habitat loss and negative impacts to biodiversity. Insects form a significant component of forest biodiversity, yet forest-dwelling pollinators remain understudied, and little is known about how management strategies affect forest insect pollinator communities.

- Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi
Sammanfattning : With an increasing global temperature, at rates twice as fast as the global average in the northern boreal forests, an increasing wildfire frequency is to be expected. Previous studies have shown that forest areas in Eurasia with high risk of wildfires today are expected to more than double in size in the following 30 years. LÄS MER
