Temporal patterns in Saturnidae (silk moth) and Sphingidae (hawk moth) assemblages in protected forests of central Uganda
(Peer reviewed; Journal article, 2015-03-25)Forest-dependent biodiversity is threatened throughout the tropics by habitat loss and land-use intensification of the matrix habitats. We resampled historic data on two moth families, known to play central roles in many ... -
Temporal trends in shade sensitive epiphytic cryptogams residing on old trees
(Master thesis, 2013-08-22)Question: How does abandoned management affect species assemblages of shade sensitive bryophytes and lichens residing on old trees in traditionally light- open environments? Method: I examined compositional change over 20 ... -
The temporal window of ecological adaptation in postglacial lakes: a comparison of head morphology, trophic position and habitat use in Norwegian threespine stickleback populations
(Peer reviewed; Journal article, 2016-05-13)Background Studying how trophic traits and niche use are related in natural populations is important in order to understand adaptation and specialization. Here, we describe trophic trait diversity in twenty-five Norwegian ... -
Temporal constraints on reproduction and growth in a seasonal environment
(Doctoral thesis, 2021-06-16)The variety of life forms is one of the most striking phenomena that have stimulated research in evolutionary biology and ecology over recent decades. The crucial role in defining the most characteristic features of living ... -
Ten priority questions for increasing the consistency and success in hatchery production of the European flat oyster for habitat restoration
(Journal article; Peer reviewed, 2023)The European flat oyster, Ostrea edulis, once formed extensive reef habitats throughout European seas and estuaries. These reefs are now largely functionally extinct, yet interest and support for their restoration is rapidly ... -
Tenacibaculosis in Norwegian Atlantic salmon (Salmo salar) cage-farmed in cold sea water is primarily associated with Tenacibaculum finnmarkense genomovar finnmarkense
(Journal article; Peer reviewed, 2022)Skin conditions associated with Tenacibaculum spp. constitute a significant threat to the health and welfare of sea-farmed Atlantic salmon (Salmo salar L.) in Norway. Fifteen presumptive tenacibaculosis outbreaks distributed ... -
Tenacibaculosis in Norwegian farmed Atlantic salmon
(Doctoral thesis, 2018-12-06)Tenacibaculosis is a bacterial ulcerative skin disease of many economically important farmed fish species worldwide caused by members of genus Tenacibaculum. For the Norwegian salmon farming industry, however, tenacibaculosis ... -
Tenacibaculum finnmarkense sp. nov., a fish pathogenic bacterium of the family Flavobacteriaceae isolated from Atlantic salmon
(Peer reviewed; Journal article, 2016-02)A novel Gram-stain negative, aerobic, non-flagellated, rod-shaped gliding bacterial strain, designated HFJT, was isolated from a skin lesion of a diseased Atlantic salmon (Salmo salar L.) in Finnmark, Norway. Colonies were ... -
Tenkemåte hos biologistudenter En kvalitativ studie av hvordan biologistudenters tenkemåte er preget av å være vekstbasert eller fastlåst
(Master thesis, 2019-06-22)Denne studien tar sikte på å gi innsyn i hvilken tenkemåte som preger biologistudentene ved UiB. Tenkemåte i denne studien blir sett ut fra hva studentene tenker om formbarheten til intelligens og evner, og hvordan de ... -
The terrestrial invertebrate fauna of Edgeøya, Svalbard: Arctic landscape community composition reflects biogeography patterns
(Peer reviewed; Journal article, 2019-05)Colonisation and immigration history is often neglected as a factor when investigating community or species distribution patterns. However, for dynamic systems that are still reacting to large-scale environmental change, ... -
Terrestrial pollen record of recent land-use changes around nine North African lakes in the CASSARINA Project
(Peer reviewed; Journal article, 2001)Pollen analyses and related plant macrofossil records are presented from short cores from nine North African lakes in the EU-funded CASSARINA project. Terrestrial pollen reflects human impact on the vegetation and landscape ... -
A test of local adaptation to drought in germination and seedling traits in populations of two alpine forbs across a 2000 mm/year precipitation gradient
(Journal article; Peer reviewed, 2023)Seed regeneration is a critical stage in the life histories of plants, affecting species' abilities to maintain local populations, evolve, and disperse to new sites. In this study, we test for local adaptations to drought ... -
A test of migratory coupling in the salmon-trout predator-prey complex of a subarctic fjord
(Peer reviewed; Journal article, 2019)Atlantic salmon (Salmo salar) smolts are vulnerable to predators during their seaward migration. To determine whether sea trout (Salmo trutta) exhibit a coupled migration to exploit the smolt run, we tracked Atlantic salmon ... -
Testing av vaksinasjonsregimer for rognkjeks, Cyclopterus lumpus, mot Aeromonas salmonicida
(Master thesis, 2017-06-16)The salmon louse (Lepeophthheirus salmonis) is currently the most serious problem in Norwegian salmon aquaculture. The increase in prevalence of salmon lice with reduced sensitivity to several different chemicals i.e. ... -
Testing macroecological abundance patterns: The relationship between local abundance and range size, range position and climatic suitability among European vascular plants
(Journal article; Peer reviewed, 2020)Aim A fundamental question in macroecology centres around understanding the relationship between species’ local abundance and their distribution in geographical and climatic space (i.e. the multi-dimensional climatic space ... -
