Establishment of Pinus wallichiana on a Himalayan glacier foreland: stochastic distribution or safe sites?
(Peer reviewed; Journal article, 2006)The establishment of tree seedlings in primary succession is thought to occur only after an adequate reserve of nutrients has accumulated in the soil. Individuals of Pinaceae are sometimes reported to grow on very recently ... -
Estimating Fish Densities from Single Fish Echo Traces
(Peer reviewed; Journal article, 2009)Estimating mean fish density per unit area has been done by counting single fish echo traces with a split beam echo sounder system in the open sea. A data program has been written that scans the acoustic signals for echo ... -
Estimating genetic diversity in a domesticated population of Norwegian Atlantic salmon (Salmo salar) using genomic data
(Master thesis, 2017-12-15)New developments of high throughput sequencing technologies have allowed for breeders to assess values related to loss of genetic diversity in domesticated animals on a genomic level for better accuracy than the pedigree ... -
Estimating global artisanal fishing fleet responses in an era of rapid climate and economic change
(Journal article; Peer reviewed, 2023)There is an urgent need to assess the extent to which the global fishing enterprise can be sustainable in the face of climate change. Artisanal fishing plays a crucial role in sustaining livelihoods and meeting food security ... -
Estimating unreported catches in Norwegian fisheries
(Doctoral thesis, 2022-06-27)A discard ban for fish was introduced in Norway in 1987, which requires that all commercial catches must be landed and reported. In theory, this regulation creates a full record of total removals from all fisheries. However, ... -
Estimation of discards in the commercial trawl fishery for Northeast Arctic cod (Gadus morhua L.) and some effects on assessment
(Master thesis, 2001)Discarding of small fish has been and still is a large problem in many fisheries. It is a problem because most of the discarded fish die and are a direct loss to the biomass of the stock. When discards occur and it is not ... -
Et Killing the Winner-studie av visuelle og taktile organismer i Svartehavet
(Master thesis, 2016-06-01)I løpet av de to siste tiårene har det blitt rapportert om trender som tyder på at det er en økning i manetblomstringer i flere store marine økosystemer. Parallelt med den økende oppblomstringen av maneter er det også ... -
Et longitudinelt studium av utvalgte gjellepatogener assosiert med gjellesykdom hos oppdrettslaks i Vest-Norge.
(Master thesis, 2015-01-08)Studien var en longitudinel undersøkelse av forekomst av gjellepatogener. En populasjon av høstutsatt Atlantisk laks på Vestlandet ble fulgt gjennom ett år i sjø (oktober 2013 - september 2014). Det ble utført månedlige ... -
The European Forest Plant Species List (EuForPlant): Concept and applications
(Journal article; Peer reviewed, 2022)Question When evaluating forests in terms of their biodiversity, distinctiveness and naturalness, the affinity of the constituent species to forests is a crucial parameter. Here we ask to what extent are vascular plant ... -
Evaluating effort regulation in mixed fisheries: a Monte Carlo approach
(Peer reviewed; Journal article, 2019)This paper evaluates whether effort regulation could achieve the goal of protecting low-abundance species in mixed fisheries. We construct a two-species bio-economic model and compare the stock abundance ratio in the end ... -
Evaluating primary (cry1Ab) and secondary effects (deoxynivalenol) of GM maize when fed to zebrafish (Danio rerio). Investigating growth, intestinal mRNA and white blood cell differentiation
(Master thesis, 2012-06-01)Several of the plants which are currently being used in fish feed in Norway today, are being genetically modified (GM) around the world. The use of GM plants is increasing worldwide, and whether these are safe to use in ... -
Evaluating the Representation of Community Colleges in Biology Education Research Publications following a Call to Action
(Journal article; Peer reviewed, 2022)Interest in biology education research (BER) has been growing over the last two decades, yet few BER publications focus on community colleges, which serve a large percentage of the undergraduate student population and a ... -
Evaluating the suitability of RAS culture environment for rainbow trout and Atlantic salmon: A ten-year progression of applied research and technological advancements to optimize water quality and fish performance
(Doctoral thesis, 2020)Over the last several decades, recirculating aquaculture systems (RAS) have become a viable technology for the production of high-value food-fish. In Norway, for example, many Atlantic salmon smolt farms are now using RAS, ... -
Evaluating the utility of a Novel Harvest Control Rule in the management of long-lived sporadically recruiting species through Management Strategy Evaluation
(Master thesis, 2019-08-16)Fish species that exhibit sporadic recruitment, late maturity and that are long-lived, can be difficult to manage. The issue arises from the high variability in stock dynamics. Where there are significant interannual ... -
An evaluation of 0-group abundance indices of Barents Sea fish stocks
(Peer reviewed; Journal article, 2009-01-23)The International 0-group fish survey in the Barents Sea (1965-2002) aimed to give initial indication of the recruiting year class strengths. Since 2003 the 0-group survey has been a part of a Joint Norwegian-Russian ... -
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 ... -
Evaluation of black soldier fly larvae meal as a functional feed ingredient in Atlantic salmon (Salmo salar) under farm-like conditions
(Journal article; Peer reviewed, 2023)Atlantic salmon (Salmo salar) were fed diets containing black soldier fly larvae (BSFL) meal at two inclusion levels for 13 months in open sea-cages. BSFL meal replaced plant-based ingredients and dietary insect meal ... -
Evaluation of harvest control rules: simple one-parameter versus complex multi-parameter strategies
(Master thesis, 2004)Harvest control rules (HCR) are sets of well-defined rules that can be used for determining annual fish catch quotas or effort. If a management policy can be expressed as a HCR, then the HCR provides means to determine the ... -
