1. 1. The effect of the COVID-19 lockdown on the spatial ecology of moose in an area with high recreational activity

   Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

   Författare :Maximilian Dörr; [2024]
   Nyckelord :Moose; Alces alces; habitat selection; tourism; human disturbance; activity; movement; speed; seasons; Covid-19; pandemic;

   Sammanfattning : In diverse landscapes, the coexistence of wildlife habitat requirements and human land use often leads to conflicts, posing challenges for sustainable species management. Recreational activities, especially in sparsely populated areas, frequently disturb wildlife behavior, necessitating a comprehensive assessment of anthropogenic impacts on habitats. LÄS MER

3. 2. Fungal Effects on Tree Growth in a Primary Succession

   Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :August Hedberg; Julian Säflund; [2023]
   Nyckelord :primary succession; succession; ectomycorrhiza; saprotroph; tree growth; Pinus sylvestris; soil fungi;

   Sammanfattning : In the Boreal zone, ectomycorrhiza is the most common mycorrhiza found among trees and helps with nitrogen and nutrient uptake. Most research on mycorrhiza, its effect, and community development are done on secondary succession (succession in an ecosystem after a disturbance) such as after a clearcut. LÄS MER

4. 3. Effects of soil factors on pioneer bryophyte species composition

   Master-uppsats, Lunds universitet/Examensarbeten i biologi

   Författare :Dora Mijić; [2023]
   Nyckelord :Biology and Life Sciences;

   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.

5. 4. Beetle Diversity – Land Sparing or Land Sharing? : the effects of timber extraction and restoration method on saproxylic beetle assemblages in mature managed pine forests

   Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Ella Amnéus; Sebastian Hjelström; [2023]
   Nyckelord :Saproxylic Beetles; Ecological Restoration; Deadwood; Biodiversity; Boreal Forest; Fire Ecology; Land-sparing; Land-sharing; Conservation Management;

   Sammanfattning : The impoverishment of saproxylic beetle communities is a growing concern for management of boreal forest biodiversity. Past research has found active restoration methods, such as creating deadwood and conducting prescribed burnings, to have a short-term positive effect on the species richness and compositional diversity of saproxylic beetle assemblages.

7. 5. Increased carbon sequestration of actively restored tropical forests in Sabah, Malaysia : a comparison of natural regeneration and active restoration

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Johan Engström; [2023]
   Nyckelord :Degraded tropical forest; Active restoration; Carbon sequestration; Natural regeneration; Enrichment planting; Biomass accumulation;

   Sammanfattning : As restoration with assisted natural regeneration and enrichment planting becomes a more important and popular method to restore ecosystem services and mitigate negative climate effects, these treatments and their effectiveness is heavily debated. There are three main groups of opinions regarding restoration, one is that humans actively need to help nature recover and the second is that nature itself does a better job without our help and the third is somewhere in between.
