Acid-base regulation and metabolite responses in shallow- and deep-living marine invertebrates during environmental hypercapnia
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:180, Doctoral thesis, 2012)Global warming is considered to be the most adverse consequence from the increasing anthropogenic emissions of CO2. However, in the marine environment additional problems related to the elevated levels atmospheric CO2 may ... -
Adaptive responses to environmental stochasticity on different evolutionary time-scales
(Doctoral theses at NTNU;2019:154, Doctoral thesis, 2019)All life on earth needs to cope with unpredictable (stochastic) environmental variation, and has evolved to do so. However, environmental conditions are currently changing not only in their average levels (e.g. warmer, ... -
Adsorption of phenanthrene to carbon nanotubes and its influence on phenanthrene bioavailability/toxicity in aquatic organisms
(Doctoral theses at NTNU;2017:323, Doctoral thesis, 2017)Carbon nanotubes (CNTs) are engineered nanomaterials (ENMs) which due to their unique properties are being incorporated into a growing number of applications. The increased production and use of CNTs increases the risk of ... -
Advancing Methods for Sampling and Analysis of Microplastics in the Marine Environment
(Doctoral theses at NTNU;2024:24, Doctoral thesis, 2024)Plastic pollution is one of many growing anthropogenic stressors in the marine environment, and its proliferation and effects are not fully understood. Research reporting abundance of plastic debris in the environment is ... -
Anthropogenic and Environmental factors driving the Human-Elephant Conflict in Myanmar
(Doctoral theses at NTNU;2022:226, Doctoral thesis, 2022)Anthropogenic activities are responsible for accelerating the depletion and deterioration of natural habitats for elephants. Habitat loss and fragmentation cause intense Human-Elephant Conflict (HEC) in multiple-use ... -
Anthropogenic and natural influence on disease prevalence at the humanlivestockwildlife interface in the Serengeti ecosystem, Tanzania
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:220, Doctoral thesis, 2012)Anthropogenic activities in ecosystems interfere with natural processes and cause habitat fragmentation and loss. Habitat fragmentation and loss restrict wildlife movement between populations consequently reducing the gene ... -
Application of Semantic Web Technology to Establish Knowledge Management and Discovery in the Life Sciences
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:56, Doctoral thesis, 2014)The last three decades has seen the successful development of many high-throughput technologies that have revolutionised and transformed biological research. The application of these technologies has generated large ... -
Arabidopsis thaliana L. adaptation mechanisms to microgravity through the EMCS MULTIGEN-2 experiment on the ISS:: The science of space experiment integration and adaptation to simulated microgravity
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:97, Doctoral thesis, 2011) -
Arabidopsis thaliana Responses to Aphid Infestation
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:193, Doctoral thesis, 2008)Interactions between plants and herbivorous insects, as they are shaped today, result from a long process of evolutionary adaptation. A whole arsenal of defence mechanisms has been developed to protect plants from a variety ... -
An assessment of field techniques to estimate lion presence and abundance
(Doctoral theses at NTNU;2022:396, Doctoral thesis, 2022)Large carnivores play a critical role in regulating ecosystems through predation and competition. Many large carnivores however have experienced a large population decline. The common causes of the decline are human related ... -
Assisted recovery of disturbed arctic and alpine vegetation : an integrated approach
(Doctoral thesis, 2003) -
Behavioural Ecology of Free-ranging and Reintroduced African Wild Dog (Lycaon pictus) Packs in the Serengeti Ecosystem, Tanzania
(Doctoral theses at NTNU;2017:154, Doctoral thesis, 2017)Worldwide, large carnivore conservation has become an increasing challenge in the face of human population growth and anthropogenic development adjacent to protected areas. African wild dogs (Lycaon pictus) range widely ... -
Behavioural effects on environmental pollution in threespine stickleback Gasterosteus aculeatus L
(Doctoral thesis, 2003)The aims of this study were to investigate the effects of known environmental contaminants on defined behavioural variables in fish, and to discuss properties of these behavioural traits that make them useful as potential ... -
Bio-optics and Ecology in Emiliania huxleyi Blooms: Field and Remote Sensing Studies in Norwegian Waters
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:337, Doctoral thesis, 2012) -
Biodiversity dynamics in urban areas under changing land-uses
(Doctoral theses at NTNU;2021:107, Doctoral thesis, 2021)Ecology goes to town Urbanisation is increasing worldwide, but as urban expansion inevitably happens at the cost of other ecosystems, understanding how this will affect biodiversity is crucial. Especially if we wish to ... -
Biofouling in the Norwegian Salmon Farming Industry
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:320, Doctoral thesis, 2013)Biofouling, the unwanted growth of organisms on submerged artificial surfaces, is ubiquitous in the marine environment and a particular problem in the salmon farming industry. In Norway, one of the most common and problematic ... -
Brood Parasitism in Asian Cuckoos: Different Aspects of Interactions between Cuckoos and their Hosts in Bangladesh
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:198, Doctoral thesis, 2011)The interaction between brood parasitic cuckoos and their hosts represents a traditional example of coevolution, whereby obligate interspecific brood parasitic cuckoos completely rely on their hosts to do their parental ... -
Bushmeat hunting in the western Serengeti: Implications for community-based conservation
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:66, Doctoral thesis, 2007)Bushmeat hunting is identified as the major threat to wildlife in sub-Saharan Africa. The trade which includes both rural and urban dwellers is linked to deforestation, and especially the development of roads, which has ... -
Carbon budget consequences of deciduous shrub expansion in alpine tundra ecosystems
(Doctoral theses at NTNU;2018:256, Doctoral thesis, 2018)Arctic and alpine tundra ecosystems are important for global carbon sequestration, as they store more than half of the global soil carbon (C), and these systems are predicted to have the greatest soil C loss following ... -
