Remote Sensing of the Tautra Ridge: An Overview of the World’s Shallowest Cold-Water Coral Reefs
(Peer reviewed; Journal article, 2022)On the Tautra Ridge – a 39-100 m deep morainic sill located in the middle of the Trondheimsfjord, Norway – some of the world’s shallowest known occurrences of the scleractinian cold-water coral (CWC) Desmophyllum pertusum ... -
Repeatability and Flexibility in the Migration Strategies of an Arctic Seabird
(Master thesis, 2016)The strategy of migration has evolved independently in many animal groups, but it is most widely and well developed in birds. Migrating species are expected to be severely affected by human induces climate change, and the ... -
Repeatability in isotopic signatures is linked to consistent individual migration strategies and individual specialization in a long-distance migratory seabird
(Master thesis, 2018)Animal populations can consist of specialized individuals with different foraging strategies. There could be several advantages for specialized individuals, such as higher foraging efficiency, breeding success and survival. ... -
Repeatable individual variation in migration timing in two anadromous salmonids and ecological consequences
(Journal article; Peer reviewed, 2020)Consistent individual differences in behavior have been demonstrated for many animals, but there are few studies of consequences of such repeated behavior in the wild. We tested consistency in migration timing to and from ... -
Repeatable Territorial Aggression in a Neotropical Poison Frog
(Peer reviewed; Journal article, 2022)Intra-specific aggressive interactions play a prominent role in the life of many animals. While studies have found evidence for repeatability in boldness, activity, and exploration in amphibians, we know relatively little ... -
Representation of pheromones, interspecific signals, and plant odors in higher olfactory centers; mapping physiologically identified antennal-lobe projection neurons in the male heliothine moth
(Journal article; Peer reviewed, 2014)The arrangement of anatomically separated systems for information about general and pheromone odorants is well documented at the initial levels of the olfactory pathway both in vertebrates and insects. In the primary ... -
Reproductive and migratory challenges inflicted on migrant brown trout ( Salmo trutta L. ) in a heavily modified river
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:136, Doctoral thesis, 2012) -
Reproductive strategies in Scandinavian brown bears
(Doctoral thesis, 2003)Denne avhandlingen tar for seg noen sentrale aspekt ved reproduktive strategier hos brunbjørn. Første del tar for seg strategier for foreldreomsorg og hvordan disse påvirker størrelsen og overlevelsen på avkommet. Deretter ... -
Requirements Elicitation On Integrating Clinical Guidelines To Electronic Patient Record: An Empirical Study
(Master thesis, 2012)There is little research on the requirements elicitation of integrating of clinical guidelines and electronic patient record while in this master project I managed to use different methods to collect and elicit requirements ... -
Research on sablefish (Anoplopoma fimbria) suggests that limited capacity to increase heart function leaves hypoxic fish susceptible to heat waves
(Peer reviewed; Journal article, 2021)Studies of heart function and metabolism have been used to predict the impact of global warming on fish survival and distribution, and their susceptibility to acute and chronic temperature increases. Yet, despite the fact ... -
Research progress on gut health of farmers teleost fish: a viewpoint concerning the intestinal mucosal barrier and the impact of its damage
(Journal article; Peer reviewed, 2020) -
Resident bird species track inter-annual variation in spring phenology better than long-distance migrants in a subalpine habitat
(Journal article; Peer reviewed, 2022) -
Resource allocation under stress: mechanisms and strategies in a long-lived bird
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:25, Doctoral thesis, 2014)The marine environment is currently undergoing critical modification in the wake of global climate change. Marine animals are, consequently, expected to experience increasing periods of nutritionally stressful conditions. ... -
Resource utilization by the Kori bustard in the Serengeti ecosystem
(Journal article; Peer reviewed, 2019)This study aimed to understand the movement behaviour and utilization distributions of Kori bustards in space and time in the Serengeti ecosystem. A total of 14 individuals were tracked with the aid of GPS (Geographical ... -
Resources for fish feed in future mariculture
(Journal article; Peer reviewed, 2011)ABSTRACT: There is a growing concern about the ability to produce enough nutritious food to feed the global human population in this century. Environmental conflicts and a limited freshwater supply constrain further ... -
Responding to the weather: energy budgeting by a small mammal in the wild
(Journal article; Peer reviewed, 2019)Energy conservation is paramount for small mammals because of their small size, large surface area to volume ratio, and the resultant high heat loss to the environment. To survive on limited food resources and to fuel their ... -
Responses in the bacterial community structure to waste nutrients from aquaculture: an in situ microcosm experiment in a Chilean fjord
(Journal article; Peer reviewed, 2017)Chilean salmon farms release inorganic nutrients excreted by the fish into the surrounding water in Patagonian fjords. The objective of this experiment from the Comau Fjord (42.2° S) in southern Chile was to study how ... -
Responses in the microbial food web to increased rates of nutrient supply in a southern Chilean fjord: Possible implications of cage aquaculture
(Journal article; Peer reviewed, 2014)ABSTRACT: Cage fish farms release the inorganic nutrients ammonium (NH4) and phosphate (PO4) into the surrounding water. The objectives of this experiment from the Comau fjord (42.2° S) in southern Chile was to study how ... -
Responses of neurogenesis and neuroplasticity related genes to elevated CO2 levels in the brain of three teleost species
(Journal article; Peer reviewed, 2017)The continuous increase of anthropogenic CO2 in the atmosphere resulting in ocean acidification has been reported to affect brain function in some fishes. During adulthood, cell proliferation is fundamental for fish brain ... -
A retrospective investigation of feather corticosterone in a highly contaminated white-tailed eagle (Haliaeetus albicilla) population
(Peer reviewed; Journal article, 2023)Exposure to persistent organic pollutants (POPs), such as organochlorines (OCs) and polybrominated diphenyl ethers (PBDEs), is associated with adverse health effects in wildlife. Many POPs have been banned and consequently ...
