An investigation into animal personality in early benthic phase European lobster (Homarus gammarus)
Gilbreath, Ashley Ann (Master thesis, 2016)Consistent individual differences in behavior, also known as animal personality, have been described across a wide range of taxa. In this study, evidence for animal personality was investigated in the European lobster, an ... -
Artificial selection on allometry: change in elevation but not slope
Egset, Camilla Kalvatn; Hansen, Thomas F; Le Rouzic, Arnaud; Bolstad, Geir Hysing; Rosenqvist, Gunilla; Pelabon, Christophe (Journal article; Peer reviewed, 2012)To what extent within-species (static) allometries constitute a constraint on evolution is the subject of a long-standing debate in evolutionary biology. A prerequisite for the constraint hypothesis is that static allometries ... -
Benefits of Multiple Mating in guppy (Poecilia reticulata)
Mathisen, Maria Kristin (Master thesis, 2013)Benefits of Multiple Mating in guppy (Poecilia reticulata) -
Distinguishing animal personality and innovation in the guppy - the effect of sex and body size
Berdal, Monica Anderson (Master thesis, 2015)How individuals within the same population show consistent differences in different behaviours, i.e. animal personalities, and how these correlate into a wider behavioural syndrome has become a hot topic in behavioural ... -
Do the invasive fish species round goby (Neogobius melanostomus) and the native fish species viviparous eelpout (Zoarces viviparus) compete for shelter?
Gullichsen, Thea Bjørnsdatter (Master thesis, 2019)Introduksjon av arter forårsaket av mennesker har økt enormt over de siste tiårene, med økende transport og handel på tvers av landegrenser. Etablering av invasive arter i et nytt miljø kan resultere i drastiske endringer ... -
Does Immune Response Influence Mate Choice in Sex Role Reversed Pipefish?
Jørgensen, Guro Øistensen (Master thesis, 2014)Vibrio sp. is the most diverse and abundant pathogenic bacteria in aquatic environments. This pathogen gets more abundant at warmer temperatures and low salinity. The Baltic Sea is more affected by climate change than ... -
Effects of an Offshore Eind Farm (OFW) on the Common Shore Crab Carcinus maenas: Tagging Pilot Experiments in the Lillegrund Offshore Wind Farm (Sweden).
Langhamer, Olivia; Holand, Håkon; Rosenqvist, Gunilla (Journal article; Peer reviewed, 2016)Worldwide growth of offshore renewable energy production will provide marine organisms with new hard substrate for colonization in terms of artificial reefs. The artificial reef effect is important when planning offshore ... -
Geographical variation in allometry in the guppy (Poecilia reticulata)
Egset, Camilla Kalvatn; Bolstad, Geir Hysing; Rosenqvist, Gunilla; Endler, John A; Pelabon, Christophe (Journal article; Peer reviewed, 2011)Variation in static allometry, the power relationship between character size and body size among individuals at similar developmental stages, remains poorly understood. We tested whether predation or other ecological factors ... -
Influence of Offshore Wind Farm on Shore Crab Carcinus maenas Population Dynamics
Meisingset, Kristine Kiplesund (Master thesis, 2013)Many governments have initiated programs of energy production from renewable sources in response to climate changes induced by gases from burning fossil fuels. Use of wind energy is considered a sustainable way of reducing ... -
Innovation as part of a wider behavioural syndrome in the guppy: The effect of sex and body size
Berdal, Monica Anderson; Rosenqvist, Gunilla; Wright, Jonathan (Journal article; Peer reviewed, 2018)Recent work on animal personalities has shown that individuals within populations often differ consistently in various types of behaviour and that many of these behaviours correlate among individuals to form behavioural ... -

Mate choice in straight-nosed pipefish (Nerophis ophidion) may be affected by increasing turbidity in the Baltic Sea
Myhren, Siri (Master thesis, 2013)Mate choice in straight-nosed pipefish (Nerophis ophidion) may be affected by increasing turbidity in the Baltic Sea -
On the relationship between ontogenetic and static allometry
Pelabon, Christophe; Bolstad, Geir Hysing; Egset, Camilla Kalvatn; Cheverud, James M.; Pavlicev, Mihaela; Rosenqvist, Gunilla (Journal article; Peer reviewed, 2013)Ontogenetic and static allometries describe how a character changes in size when the size of the organism changes during ontogeny and among individuals measured at the same developmental stage, respectively. Understanding ... -
Reduced sexual size dimorphism in a pipefish population where males do not prefer larger females
Cunha, Mario; Macedo, Nidia; Wilson, Jonathan; Rosenqvist, Gunilla; Berglund, Anders; Monteiro, Nuno (Journal article; Peer reviewed, 2019)Within a species' distribution, populations are often exposed to diverse environ‐ments and may thus experience different sources of both natural and sexual selec‐tion. These differences are likely to impact the balance ... -
Round goby (Neogobius melanostomus) - a potential threat to northern pike (Esox lucius) recruitment in the Swedish Baltic Sea coastline?
Andresen, Katrine (Master thesis, 2019)Invasive arter er en stor trussel mot akvatisk biodiversitet verden over, da de fører til sterke økologiske virkninger i akvatiske økosystemer. En svært suksessfull invasiv fiskeart er svartmunnet kutling (Neogobius ... -
Sex in murky waters: algal induced turbidity increases sexual selection in pipefish
Sundin, Josefin; Aronsen, Tonje; Rosenqvist, Gunilla; Berglund, Anders (Journal article; Peer reviewed, 2017)Algal-induced turbidity has been shown to alter several important aspects of reproduction and sexual selection. However, while turbidity has been shown to negatively affect reproduction and sexually selected traits in some ... -
Stress influence of offshore wind farms on the reproduction of the viviparous eelpout (Zoarces viviparus)
Oehninger-Storvoll, Karen-Christine (Master thesis, 2013)Okende behov for fornybar energi har skapt en økning av installasjoner for fornybar marin energi. Disse installasjonene varierer fra bølge- og tidevannskraft til offshore vindkraft. Påvirkning av offshore vindkraft på ... -
The effect of purging on sexually selected traits through antagonistic pleiotropy with survival
Bolstad, Geir Hysing; Pelabon, Christophe; Larsen, Line-Kristin; Fleming, Ian A.; Viken, Åslaug; Rosenqvist, Gunilla (Journal article; Peer reviewed, 2012)Sexually selected traits are expected to evolve to a point where their positive effect on reproductive success is counterbalanced by their negative effect on survival. At the genetic level, such a trade-off implies ...
