Context Consistency and Seasonal Variation in Boldness of Male Two-Spotted Gobies
Magnhagen, Carin; Wacker, Sebastian; Forsgren, Elisabet; Myhre, Lise Cats; Amundsen, Trond; Espy, Elizabeth (Journal article; Peer reviewed, 2014)In order to attribute the behaviour of an animal to its personality it is important to study whether certain behavioural traits show up consistently across a variety of contexts. The aim of this study was to investigate ... -
Effects of Nest Spacing on Nest Occupation, Mating Success and Mating Behaviour in the Two-spotted Goby (Gobiusculus flavescens)
Mück, Isabel Magdalena (Master thesis, 2011)I investigated hoe different spacing of breeding sited affects different aspects of mating behaviour in the two-spotted goby. I found that clumped nest spacing affects nest occupations and reproductive success negatively. ... -
Elevated CO2 affects embryonic development and larval phototaxis in a temperate marine fish
Forsgren, Elisabet; Dupont, Sam; Jutfelt, Fredrik; Amundsen, Trond (Journal article; Peer reviewed, 2013)As an effect of anthropogenic CO2 emissions, the chemistry of the world’s oceans is changing. Understanding how this will affect marine organisms and ecosystems are critical in predicting the impacts of this ongoing ocean ... -
Sex roles and sexual selection: Lessons from a dynamic model system
Amundsen, Trond (Journal article; Peer reviewed, 2018)Our understanding of sexual selection has greatly improved during the last decades. The focus is no longer solely on males, but also on how female competition and male mate choice shape ornamentation and other sexually ... -
Territoriality and nest competition in the two-spotted goby (Pomatoschistus flavescens)
Gavriilidi, Ioanna Aikaterini (Master thesis, 2019)Intra-sexual competition plays an important role in the evolutionary process of sexual selection. Male-male competition over resources that are essential for mating success may prevent unsuccessful competitors from breeding. ... -
The effect of body size on intrasexual competition in the coral reef fish Chrysiptera cyanea
Ness, Miriam Horstad (Master thesis, 2015)Intrasexual competition is considered important in driving selection on morphological traits, and the role of body size in male-male competition is well studied in a wide range of animals. In coral reef fishes however, ...
