Molecular mechanisms of Charcot-Marie-Tooth neuropathy linked to mutations in human myelin protein P2
(Peer reviewed; Journal article, 2017-07-26)Charcot-Marie-Tooth (CMT) disease is one of the most common inherited neuropathies. Recently, three CMT1-associated point mutations (I43N, T51P, and I52T) were discovered in the abundant peripheral myelin protein P2. These ... -
Molecular phylogenies challenge the classification of Polymastiidae (Porifera, Demospongiae) based on morphology
(Peer reviewed; Journal article, 2016)Polymastiidae Gray, 1867 is a worldwide distributed sponge family, which has a great significance for understanding of the demosponge deep phylogeny since the former order Hadromerida Topsent, 1894 has been recently split ... -

(Peer reviewed; Journal article, 2011-04-08)Background: The Astrophorida (Porifera, Demospongiaep) is geographically and bathymetrically widely distributed. Systema Porifera currently includes five families in this order: Ancorinidae, Calthropellidae, Geodiidae, ... -
The molecular regulation of molting in the salmon louse (Lepeophtheirus salmonis)
(Doctoral thesis, 2021-12-10)The salmon louse, Lepeophtheirus salmonis, is a copepod and an ectoparasite that infects salmonids in the Northern hemisphere. At present, salmon louse infestations are the biggest threat to the health and welfare of wild ... -
Molecular systematics of the long-snouted deep water dogfish (Centrophoridae, Deania) with implications for identification, taxonomy and conservation.
(Journal article; Peer reviewed, 2021-01-20)According to the most recent taxonomical revision, the deep-sea dogfish genus Deania encompasses four species. Three of them, D. calcea, D. profundorum, and D. hystricosa, occur in the North Atlantic. Whilst D. profundorum ... -
Molecular tools for the detection and identification of Ichthyobodo spp. (Kinetoplastida), important fish parasites
(Peer reviewed; Journal article, 2012-12)Ichthyobodo spp. are ectoparasitic flagellates of fish that may cause disease (ichthyobodosis), a common problem affecting the aquaculture industry worldwide. Ichthyobodosis in farmed fish is often associated with a range ... -
Monitoring litter and microplastics in Arctic mammals and bird
(Journal article; Peer reviewed, 2022)Plastic pollution has been reported to affect Arctic mammals and birds. There are strengths and limitations to monitoring litter and microplastics using Arctic mammals and birds. One strength is the direct use of these ... -
Monitoring of microplastic pollution in the Arctic: Recent developments in polymer identification, quality assurance and control (QA/QC), and data reporting
(Journal article; Peer reviewed, 2022)The pollution of the environment with plastics is of growing concern worldwide, including the Arctic region. While larger plastic pieces are a visible pollution issue, smaller microplastics are not visible with the naked ... -
Monsters in the dark: Systematics and biogeography of the stygobitic genus godzillius (crustacea: Remipedia) from the lucayan archipelago
(Journal article; Peer reviewed, 2021)Remipedia is a stygobitic group commonly associated with coastal anchialine caves. This class consists of 12 genera, ten of which are found within the Lucayan Archipelago. Herein, we describe a new species within the genus ... -
More than what they eat: uncoupled biophysical constraints underlie geographic patterns of herbivory
(Journal article; Peer reviewed, 2022)Herbivory rates have classically been hypothesized to decrease from the tropics towards higher latitudes because the more benign abiotic conditions in tropical systems foster greater ecosystem complexity including greater ... -
More warm-adapted species in soil seed banks than in herb layer plant communities across Europe
(Journal article; Peer reviewed, 2023)Responses to climate change have often been found to lag behind the rate of warming that has occurred. In addition to dispersal limitation potentially restricting spread at leading range margins, the persistence of species ... -
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) ... -
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 ... -
