Spatial segregation by sympatrically breeding Antarctic and Snow Petrels.
(Master thesis; Mastergradsoppgave, 2024-05-14)Sympatrically breeding species may face intense competition for resources, which can lead to various forms of segregation to mitigate competitive pressures. Segregation of space or habitats is one possible strategy, particularly when species share similar diets and foraging behaviors. This study examines the differences in space and habitat use between Antarctic and Snow Petrels (Thalassoica ... -
Motivations and Effects of Volunteer Divers Restoring Norwegian Kelp Forests
(Master thesis; Mastergradsoppgave, 2024-05-14)Kelp forests are in decline worldwide due to increasing anthropogenic pressures. Along the coastline of Northern Norway, spanning 15,000 kilometers, sea urchins have transformed the seabed from biodiverse kelp forests into barren grounds dominated by sea urchins. To address this issue, the initiative The Guardians of the Kelp engages volunteer divers in Northern Norway in monthly clearing events to ... -
Arctic Shrub Expansion: Implications for Stream Benthic Invertebrate Community Structure & Function
(Master thesis; Mastergradsoppgave, 2024-05-15)The Arctic is rapidly warming and this increase in temperature has been found to drive range expansion of tall shrubs in the Arctic tundra ecosystems. Although the consequences of shrub expansion have been studied in the terrestrial tundra, effects on tundra stream ecosystems remain understudied. Riparian tall shrubs, such as willows, can provide stream ecosystems with leaf litter and shade, enhancing ... -
