Morph-based resistance against Schistocephalus solidus in three-spined sticklebacks (Gasterosteus aculeatus) selected under different infection- and predation regimes
(Master thesis, 2013-06-07)The morphology of a host may have an effect on its resistance against parasites. Two geographically separated and morphologically divergent populations of three-spined sticklebacks (Gasterosteus aculeatus, Linnaeus, 1758) ... -
Morphine enhances doxorubicin-induced cardiotoxicity in the rat
(Peer reviewed; Journal article, 2014-09)Interventions to reduce the cardiotoxicity of doxorubicin are clinically relevant. Pharmacological preconditioning mimicking ischemic preconditioning has been demonstrated with morphine and represents an acceptable clinical ... -
Morphogenesis underlying the development of the everted teleost telencephalon
(Peer reviewed; Journal article, 2012-09-18)Background: Although the mechanisms underlying brain patterning and regionalization are very much conserved, the morphology of different brain regions is extraordinarily variable across vertebrate phylogeny. This is ... -
Morphological and functional modifications of the gastrointestinal tract during metamorphosis in Atlantic halibut (Hippoglossus hippoglossus)
(Doctoral thesis, 2014-04-23)Metamorphosis in flatfish is the transition from a symmetrical larva to an asymmetrical juvenile stage, allowing the organism to utilize new resources in a different habitat and thus providing an evolutionary advantage. ... -
Morphological and genetic variation in Hanleya nagelfar and Hanleya hanleyi (Mollusca: Polyplacophora) in the Northern European Atlantic and the phylogenetic position of Hanleyidae based on nuclear and mitochondrial genes
(Master thesis, 2010-04-23)Large specimens of the spongivore Hanleya nagelfar (Mollusca: Polyplacophora) differ noticeably from the smaller congeneric H. hanleyi, but many scientists have reported that small specimens are very similar and perhaps ... -
Morphological and genetic variation in North Atlantic synaphobranchid eels in relation to species diagnostics
(Master thesis, 2009)Synaphobranchus eels are difficult to identify at species level. A literature study of previous taxonomic work on these species revealed several inconsistencies concerning the diagnostic characters of Synaphobranchus kaupii ... -
Morphological filter detector for image forensics applications
(Journal article; Peer reviewed, 2020)Mathematical morphology provides a large set of powerful non-linear image operators, widely used for feature extraction, noise removal or image enhancement. Although morphological filters might be used to remove artifacts ... -
Morphological investigations of posttraumatic regeneration in Timarete cf. punctata (Annelida: Cirratulidae)
(Journal article; Peer reviewed, 2015-08-06)Introduction: Annelids exhibit great regenerative abilities, which are mainly used after injury or during reproduction. These lophotrochozoans thus represent excellent models for regeneration research. However, detailed ... -
Morphological ontogeny of Galumna flagellata Willmann (Acari: Oribatida: Galumnidae)
(Journal article; Peer reviewed, 2021)The morphological ontogeny of Galumna flagellata Willmann, 1925 is described and illustrated. The juveniles of this species are light brown, with prodorsal setae of medium size or long and barbed, and bothridial seta ... -
Morphological Ontogeny, Ecology, and Biogeography of Fuscozetes fuscipes (Acari, Oribatida, Ceratozetidae)
(Journal article; Peer reviewed, 2024)The systematic status of Fuscozetes Sellnick, 1928, is not clear in the literature. Therefore, the morphological ontogeny of F. fuscipes (C.L. Koch, 1844), the type species of this genus, was investigated and compared with ... -
Morphological properties of the axon initial segment-like process of AII amacrine cells in the rat retina
(Journal article; Peer reviewed, 2021)Signal processing within the retina is generally mediated by graded potentials, whereas output is conveyed by action potentials transmitted along optic nerve axons. Among retinal neurons, amacrine cells seem to be an ... -
A morphological study of the parasitic barnacle, Anelasma squalicola (Lovén, 1844)
(Master thesis, 2016-06-30)Objectives and Summary The pedunculate barnacle, Anelasma squalicola, is found parasitizing various squaloid sharks of the family Etmopteridae. Its peduncle has been modified to bury in the flesh of its host, and has ... -
Morphology and life history divergence in cave and surface populations of Gammarus lacustris (L.)
(Peer reviewed; Journal article, 2018-10-25)Cave animals provide a unique opportunity to study contrasts in phenotype and life history in strikingly different environments when compared to surface populations, potentially related to natural selection. As such, we ... -
Morphology control in modulated synthesis of metal-organic framework CPO-27
(Peer reviewed; Journal article, 2019)The CPO-27/MOF-74 series is among the most investigated metal-organic frameworks because of their usefulness in a diverse range of applications. For specific applications, it will be important to control the shape and size ... -
Morphology of the nervous system of monogonont rotifer Epiphanes senta with a focus on sexual dimorphism between feeding females and dwarf males
(Peer reviewed; Journal article, 2019-08-07)Background: Monogononta is a large clade of rotifers comprised of diverse morphological forms found in a wide range of ecological habitats. Most monogonont species display cyclical parthenogenesis, where generations of ... -
The morphology of the threespine stickleback and its relation to predators and parasites, from three lakes in western Norway
(Master thesis, 2011-06-01)We studied the three-spined stickleback (Gasterosteus aculeatus) in three different lakes, with respect to morphology (Dorsal spine numbers and pelvis), distribution and relationship to the parasites Schistocephalus solidus ... -
Morphometric Relationships as Indicators of Sexual Maturation in Atlantic Salmon (Salmo salar)
(Master thesis, 2023-09-01)This study aimed to identify morphometric relationships in fish that could serve as indicators for status on sexual maturation in Atlantic salmon (Salmo salar). To achieve this, 250 salmon were netted out and individually ... -
Morphomolecular alterations in the skin mucosa of Atlantic salmon (Salmo salar) after exposure to peracetic acid-based disinfectant
(Journal article; Peer reviewed, 2020)Peroxygen-based chemotherapeutants are commonly used in treating ectoparasitic infections in fish. A majority of relevant studies address the effects of these substances on the targeted causative agents, but little is known ... -
