Behaviour of brown bears (Ursus arctos) when repeatedly approached by humans on foot
(Master thesis, 2015-07-08)Knowledge about encounters between humans and wildlife is important for conservation, management and policymaking, as well as for reducing conflict and negative interactions. There is general concern that an increased ... -
Birds living on the edge : power-line corridors influence on avian communitites in Norwegian secondary coniferous forest
(Master thesis, 2012-11-16)Power-line corridor edges differ from other edge habitats by its long shape with a high amount of edge habitat compared to open fields, and the regular maintenance clearing the corridor for forest trees not allowing ... -
Change in arthropod communities following a mass death incident of reindeer at Hardangervidda
(Master thesis, 2019)Decomposition of dead material is a vital part of ecology, and an important process in every ecosystem. Dead animals are likely to play a major part in sustaining species that specialize on scavenging. The highly nutrient ... -
Condensed tannins in senesced foliage and soil organic layer in response to fertilization in boreal forest ecosystem
(Master thesis, 2021)Anthropogenic nitrogen deposition rate in boreal forests increased over the last century and significantly impacted many parts of these ecosystems. Boreal forests contain a large amount of carbon (C), and nitrogen (N) is ... -
Dung beetle (Scarabaeidae, Scarabaeinae) communities in mountain rain forests (Tanzania): A biodiversity survey from Amani Nature Reserve and Udzungwa Mountain National Park
(Master thesis, 2015-07-30)The African dung beetles (Scarabaeidae, Scarabeinae) is the most generic and species rich of the global faunas. Dung beetles are good indicators of biodiversity and habitat disturbances. This study aimed to investigate ... -
Effects of alien plant species removal on biodiversity and species interactions in two native forest areas on Mauritius
(Master thesis, 2015-11-09)Mauritius Island is one of the world’s most severely ecologically damaged nations, with less than 5% of the original forests remaining as fragments. Yet, it sustains one of the highest tree diversities of all isolated ... -
Effects of anthropogenic disturbances on ground beetle (Coleoptera, Carabidae) communities in Afromontane forests: a comparison between habitats with different levels of disturbance in Amani Nature Reserve, Tanzania.
(Master thesis, 2014-08-05)The family of ground beetles (Coleoptera, Carabidae) is one of the most species-rich coleopteran families. Ground beetles are good indicators of habitat disturbances, and could provide valuable information for sustainable ... -
Effects of long-term experimental warming on alpine bryophytes : trends in functional traits
(Master thesis, 2019)Functional traits are becoming increasingly important tools to evaluate plant community response to climate change. Artificial warming treatments can shift community-level trait values as a consequence of intraspecific ... -
Effects of weather on summer and winter activity level of the high arctic ungulate Svalbard reindeer (Rangifer tarandus platyrhynchus)
(Master thesis, 2015-08-03)Animals are evolutionary adapted to certain weather conditions, but as the climate of the earth is changing many species may face new and significant challenges in their environment. The high-Arctic species Svalbard reindeer ... -
Evaluating wildlife cameras as a method to sample reindeer behavior
(Master thesis, 2021)Increasing amounts of infrastructure intersecting reindeer habitat in Fennoscandia also increases concern over negative effects on reindeer behavior and area use. Previous studies have shown variable results regarding area ... -
Evaluation of restoration success for semi-natural and flower meadows in the Oslo municipality
(Master thesis, 2019)While cities are often overlooked as targets for conservation, ecologists have argued that the urban environment is actually a good candidate for re-creating semi-natural meadows, since these nutrient-poor grasslands prefer ... -
GIS-modeling of riparian vegetation : a case study of ecosystem services in and along Lierelva as indicated by macroinvertebrates
(Master thesis, 2020)Lierelva is a river located in SE-Norway in Auskog-Holand municipality. It has a large drainage area and joins Lake Bjorkelangen in the south. This study has two major purposes: (1) determine the various types of riparian ... -
Interaction between Bombus terrestris and honeybees in red clover fields reduces abundance of other bumblebees and red clover yield
(Master thesis, 2016-11-17)Pollinator dependent crops have increased by 300% the last 50 years. At the same time many pollinator species are declining, including honeybees and bumblebees. Red clover is one of the crops dependent on bees for seed ... -
Parasites and people : crocodile parasite interactions in human impacted areas of Belize
(Master thesis, 2019)Despite the recorded cases of crocodilian epidemic mortalities caused by human disturbance of the environment, there still remains a lack of information to understand how anthropogenic disturbances affect crocodilian health. ... -
Prey deliveries at nests of the tawny owl (Strix aluco): diet and diel pattern
(Master thesis, 2016-03-30)I used continuous video monitoring to record prey items delivered at four tawny owl (Strix aluco) nests in Akershus county in southeast Norway during May 2014. A total of 1635.5 hours of video recordings were gathered, and ... -
Responses in fish and macroinvertebrates to channelization and restoration in two Arctic rivers
(Master thesis, 2018)The two rivers Salangselva and Kvernmoelva in Troms county, were both channelized and erosion secured during the 1980s. This stimulated agricultural activity in adjacent properties in the following years. In parallel, a ... -
Scale-specific responses of saproxylic beetles to dead wood abundance and forest characteristics
(Master thesis, 2013-07-09)Insects constitute a major part of global biodiversity. Saproxylic insects seem to be adversely affected by forest management due to the low volume of dead wood in traditionally managed forests. Studies of the relation ... -
Sea trout in Inner Oslofjorden : population biology, marine recreational fishing and spatial variation in fishing intensity
(Master thesis, 2019)Recreational fishing has been known since XV century. Nowadays, Arlinghaus and Cooke (2009) estimate, that around 10,6% of the population in studied countries participate in recreational fishing. However, marine recreational ... -
Spatio-temporal ecology of Amazonian freshwater turtles
(Master thesis, 2021)Amazonian freshwater turtles are a key component of the Amazonian waterscape and an important resource for riverine communities. However, extensive exploitation combined with habitat alteration and climate change has ... -
The influence of nest-site limitation on the species richness and abundance of bees : linking biodiversity and geology
(Master thesis, 2018)There is mounting evidence of declines in global biodiversity. Declining wild bee populations are subject to concern because bees are considered the most important pollinators worldwide, contributing to the production of ...
