Comprehensive characterization of glial cells in the urochordate Ciona intestinalis
(Doctoral thesis, 2021-05-31)There are two main classes of cells that are present in the nervous system: neurons and glia. Neurons are the signalling units of the nervous system and are responsible to transmit electrical and chemical signals to other ... -
Plant traits and vegetation data from climate warming experiments along an 1100 m elevation gradient in Gongga Mountains, China
(Journal article; Peer reviewed, 2020)Functional trait data enhance climate change research by linking climate change, biodiversity response, and ecosystem functioning, and by enabling comparison between systems sharing few taxa. Across four sites along a ... -
Forest fragmentation modifes the composition of bumblebee communities and modulates their trophic and competitive interactions for pollination
(Journal article; Peer reviewed, 2020)Understanding the effects of landscape fragmentation on global bumblebee declines requires going beyond estimates of abundance and richness and evaluating changes in community composition and trophic and competitive ... -
Negative impacts of the sea lice prophylactic emamectin benzoate on the survival of hatchery released salmon smolts in rivers
(Journal article; Peer reviewed, 2020)Emamectin benzoate (EB) is a prophylactic pharmaceutical used to protect Atlantic salmon (Salmo salar) smolts migrating out of rivers and into the ocean against sea lice parasites. Randomized control trials comparing the ... -
Large annual variation in the amount of skipped spawning for female Northeast Arctic haddock Melanogrammus aeglefinus
(Journal article; Peer reviewed, 2020-10)Although the phenomenon of skipped spawning has been described in numerous fishes, time-series are scarce. We used the presence of post-ovulatory follicles in histological gonad slides from females not developing oocytes ... -
The development of early pioneer neurons in the annelid Malacoceros fuliginosus
(Journal article; Peer reviewed, 2020)Background Nervous system development is an interplay of many processes: the formation of individual neurons, which depends on whole-body and local patterning processes, and the coordinated growth of neurites and synapse ... -
New insights into the early mechanisms of epileptogenesis in a zebrafish model of Dravet syndrome
(Journal article; Peer reviewed, 2020)Abstract Objective: To pinpoint the earliest cellular defects underlying seizure onset (epileptogenic period) during perinatal brain development in a new zebrafish model of Dravet syndrome (DS) and to investigate potential ... -
Propensity for risk in reproductive strategy affects susceptibility to anthropogenic disturbance
(Journal article; Peer reviewed, 2020)Animals initiate, interrupt, or invest resources in reproduction in light of their physiology and the environment. The energetic risks entailed in an individual’s reproductive strategy can influence the ability to cope ... -
Plasma-derived exosome-like vesicles are enriched in lyso-phospholipids and pass the blood-brain barrier
(Journal article; Peer reviewed, 2020)Exosomes are vesicles involved in intercellular communication. Their membrane structure and core content is largely dependent on the cell of origin. Exosomes have been investigated both for their biological roles and their ... -
Evaluation of a eukaryote phylogenetic microarray for environmental monitoring of marine sediments
(Journal article; Peer reviewed, 2020)Increased exploitation of resources in sensitive marine ecosystems emphasizes the importance of knowledge regarding ecological impacts. However, current bio-monitoring practices are limited in terms of target-organisms and ... -
Ecological adaptation in Atlantic herring is associated with large shifts in allele frequencies at hundreds of loci
(Journal article; Peer reviewed, 2020)Atlantic herring is widespread in North Atlantic and adjacent waters and is one of the most abundant vertebrates on earth. This species is well suited to explore genetic adaptation due to minute genetic differentiation at ... -
Heads and tails: The notochord develops differently in the cranium and caudal fin of Atlantic Salmon (Salmo salar, L.)
(Journal article; Peer reviewed, 2020)While it is well known that the notochord of bony fishes changes over developmental time, less is known about how it varies across different body regions. In the development of the Atlantic salmon, Salmo salar L., cranial ... -
The Day-to-day Supply Responses of a Limited-entry Mixed Fishery
(Journal article; Peer reviewed, 2021)Small-scale fishers’ short-run supply decisions are understudied, often because of data limitations. We utilize a unique dataset of daily catches and prices from a mixed-species trawl fishery in Taiwan, characterized by ... -
Aquaculture-driven evolution: distribution of pyrethroid resistance in the salmon louse throughout the North Atlantic in the years 2000–2017
(Journal article; Peer reviewed, 2020)The parasitic salmon louse, and its documented resistance to chemotherapeutants, represents the most persistent environmental challenge to global salmonid aquaculture. We used a genetic marker associated with pyrethroid ... -
Structure and functioning of four North Atlantic ecosystems - A comparative study
(Journal article; Peer reviewed, 2020)The epi- and mesopelagic ecosystems of four sub-polar ocean basins, the Labrador, Irminger, Iceland and Norwegian seas, were surveyed during two legs from Bergen, Norway, to Nuuk, Greenland, and back to Bergen. The survey ... -
Density-dependent consequences of size-selective induced life-history changes to population fitness in medaka (Oryzias latipes)
(Journal article; Peer reviewed, 2020)There is an increasing concern about the potential for size-selective harvest to impair population persistence. Yet little is known about the relative contribution of the evolutionary (shifts in life history) and demographic ... -
Stoichiometric consequences of size-selective mortality: An experimental test using the Japanese medaka (Oryzias latipes)
(Journal article; Peer reviewed, 2020-07-01)The determinants of intraspecific stoichiometric variation remain difficult to elucidate due to their multiple ori- gins (e.g. genetic vs. environmental) and potential interactive effects. We evaluated whether two size-selected ... -
Body size adaptions under climate change: Zooplankton community more important than temperature or food abundance in model of a zooplanktivorous fish
(Journal article; Peer reviewed, 2020)One of the most well-studied biogeographic patterns is increasing body size with latitude, and recent body size declines in marine and terrestrial organisms have received growing attention. Spatial and temporal variation ... -
The transcriptomic response of adult salmon lice (Lepeophtheirus salmonis) to reduced salinity
(Journal article; Peer reviewed, 2021)Salmon lice (Lepeophtheirus salmonis) are marine parasitic copepods living on salmonids and are challenging for salmon aquaculture. One of several treatment methods is the application of freshwater to the fish which can ... -
Global phylogeography suggests extensive eucosmopolitanism in Mesopelagic Fishes (Maurolicus: Sternoptychidae)
(Journal article; Peer reviewed, 2020)Fishes in the mesopelagic zone (200–1000 m) have recently been highlighted for potential exploitation. Here we assess global phylogeography in Maurolicus, the Pearlsides, an ecologically important group. We obtained new ...
