Physiological changes observed in farmed Atlantic salmon (Salmo salar L.) with nephrocalcinosis
(Peer reviewed; Journal article, 2022)There is a growing concern for fish health and welfare in the salmon industry in Norway. Nephrocalcinosis, described as mineral deposits within the kidney, is increasingly observed. However, little is known about its ... -
Physiological Characterization of Protocerebral Neurons in the Olfactory Network of the Moth, Heliothis virescens
(Master thesis, 2011)In the sensory systems of insects, the primary olfactory centre in the antennal lobe has been one of the major areas of interest for the last two decades. Considerable progress has been made in understanding this earlier ... -
Physiological constraints to climate warming in fish follow principles of plastic floors and concrete ceilings
(Journal article; Peer reviewed, 2016-05-17)Understanding the resilience of aquatic ectothermic animals to climate warming has been hindered by the absence of experimental systems experiencing warming across relevant timescales (for example, decades). Here, we ... -
Physiological plasticity and evolution of thermal performance in zebrafish
(Doctoral theses at NTNU;2020:68, Doctoral thesis, 2020)Climate change is increasing mean and extreme temperatures globally. For aquatic ectotherms, such as fish, increasing temperatures will directly affect their thermalperformance and challenge their upper thermal limits. ... -
Phytoplankton community succession and dynamics using optical approaches
(Peer reviewed; Journal article, 2020)The phytoplankton in coastal regions are responding to constant environmental changes, thus the use of proxies derived from in situ frequent time-series observations and validated from traditional microscopic or pigment ... -
Phytoplankton spring bloom mapping in coastal areas using Autonomous Underwater Vehicle (AUV) and optical approaches
(Master thesis, 2022)Fytoplankton danner oppblomstring over mesoskalaen (ofte <37 000 km2), og derfor er studier som har forskjelling oppløsning i tid og rom nødvendige. Ved å kombinere informasjon fra flere instrumentbærende plattformer, ... -
Phytotoxic Effects of Catnip (Nepeta meyeri Benth.) on Early Growth Stages Development and Infection Potential of Field Dodder (Cuscuta campestris Yunck)
(Peer reviewed; Journal article, 2022)Dodder (Cuscuta campestris Yunck.) is one of the most devastating parasitic plants, which reduces quantity and quality of crops. The inhibitory effect of catnip (Nepeta meyeri Benth.) extracts on germination and some ... -
Pigmentation and Spectral Absorbance Signatures in Deep-Water Corals from the Trondheimsfjord, Norway
(Journal article; Peer reviewed, 2012)The pigmentation and corresponding in vivo and in vitro absorption characteristics in three different deep-water coral species: white and orange Lophelia pertusa, Paragorgia arborea and Primnoa resedaeformis, collected ... -
Pigmentation in deep water corals
(Master thesis, 2009) -
Pigmentation in the Arctic deep-sea amphipods Eurythenes gryllus and Anonyx sp.
(Master thesis, 2009) -
Pinngortitaq – a place of becoming
(Journal article; Peer reviewed, 2019)Arctic ecosystems are on the verge of changes that are unprecedented in both magnitude and velocity. We stress that statements of a changing climate and environment have ambiguous definitions in both theoretical and ... -
Pixelwise immersion factor calibration for underwater hyperspectral imaging instruments
(Journal article; Peer reviewed, 2024)In situ spectral reflectance initially captured at high spatial resolution with underwater hyperspectral imaging (UHI) is effective for classification and quantification in oceanic biogeochemical studies; however, the ... -
Plaintive Cuckoo Nestling Adaptations and Development in Common Tailorbird Nests - Costly Child Custody
(Master thesis, 2015)Avian brood parasitism represents a suitable system for studying coevolution, as parasite and host engage in an escalating arms race. The parasite develops adaptations to overcome host defences, and in addition develops ... -
Plaintive cuckoos do not select tailorbird hosts that match the phenotypes of their own eggs
(Journal article; Peer reviewed, 2016)Laying a mimetic egg is important for a brood parasite to succeed in defeating the defenses of a host that can recognize and reject nonmimetic foreign eggs. Several recent studies suggest that common cuckoos ( Cuculus ... -
Plankton responses to ocean acidification: The role of nutrient limitation
(Journal article; Peer reviewed, 2018)In situ mesocosm experiments on the effect of ocean acidification (OA) are an important tool for investigating potential OA-induced changes in natural plankton communities. In this study we combined results from various ... -
Planktonic and Parasitic Sea Lice Abundance on Three Commercial Salmon Farms in Norway Throughout a Production Cycle
(Peer reviewed; Journal article, 2021)The present article reports the densities of planktonic sea lice (Lepeophtheirus salmonis and Caligus elongatus) in three Atlantic salmon (Salmo salar) localities, and the relationship between the abundance of adult sea ... -
Planktonundersøkelser i Jonsvatnet. Årsrapport 2020
(NTNU Vitenskapsmuseet naturhistorisk notat;, Research report, 2021)I 2020 ble det gjennomført innsamlingsrunder av zoo- og phytoplankton 7 ganger fra begynnelsen av juni til månedsskiftet september/oktober med to innsamlinger med ca. 14 dagers intervall i juni, juli og august samt en ... -
Plant Biology: Plants Turn Down the Volume to Respond to Cell Swelling.
(Peer reviewed; Journal article, 2020)Turgor manipulation to induce plant cell swelling is one of the classic experiments undertaken in biology courses in schools and at universities. However, only now do we start to understand the molecular mechanisms responsible ... -
Plant cell wall integrity maintenance in model plants and crop species-relevant cell wall components and underlying guiding principles
(Journal article; Peer reviewed, 2019)The walls surrounding the cells of all land-based plants provide mechanical support essential for growth and development as well as protection from adverse environmental conditions like biotic and abiotic stress. Composition ... -
Plant clustering generates negative plant–soil feedback without changing the spatial distribution of soil fauna
(Peer reviewed; Journal article, 2023)The spatial distribution of resources affects ecological processes at all levels of biological organization. However, it remains to be tested how the spatial configuration of belowground resources affects the community ...
