Drivers and consequences of partial migration in an alpine bird species
(Master thesis, 2020)1. Partial migration, where parts of a population migrate between winter and summer (breeding) areas and the rest remain year-round resident, is a common phenomenon across several bird species. However, both drivers and ... -
Drivers for phytoplankton community dominance of nuisance microalga Gonyostomum semen (Ehrenberg) Diesing in two South-Eastern Norwegian lakes : a paleolimnological approach
(Master thesis, 2018)Gonyostomum semen (Ehr.) Diesing has during the last decades expanded its distribution and increasingly started to dominate phytoplankton communities in Northern Europe, and particularly in Scandinavia. Several studies ... -
Drivers of bat activity and habitat use in boreal forest
(PhD thesis;2024:29, Doctoral thesis, 2024)Bat species in Fennoscandia make up approximately 20% of the terrestrial mammal wildlife and are all reliant on forest habitats to some extent throughout their annual cycle. However, there is a lack of knowledge on ecological ... -
Drivers of the diversity and distribution of wild bees in a species poor region
(PhD Thesis;2016:23, Doctoral thesis, 2020-11-13)Bee diversity is declining globally. On a European scale, roughly 10% of the species are considered threatened, but the number may be even higher. The threatened status of bees depends on both the taxonomic and spatial ... -
Dry Calcareous Grasslands - Using Monitoring Methods to Detect Effects From Management Actions
(Master thesis, 2023)1. The grim fact is that biodiversity in ecosystems across the globe are rapidly declining due to anthropogenic activities. On the other hand, focus on actions that may halt this loss is on the rise. Ecological restoration ... -
