  2. 1. Reproductive traits in euryhaline gobies: insights into physiology, adaptations and biological invasions

    Author : Leon Green; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sperm; Reproduction; Life-history Strategies; Local Adaptation; Fish; Invasion Biology; Salinity;

    Abstract : Organisms are adapted to reproduce in their specific environment by a range of different traits. For many animals, reproduction is tied to specific conditions, that trigger or enable the reproductive events. This thesis deals with traits associated with reproduction, their functions and interactions with the environment. READ MORE

  4. 2. Female coloration, egg carotenoids and reproductive success: gobies as a model system

    Abstract : In two-spotted gobies (Gobiusculus flavescens), females develop an orange belly as they approach sexual maturity. Toward the end of the single breeding season, males become rare and females compete for spawnings. Nest-holding males then prefer females with more colourful bellies and this trait has been suggested to act as a female ornament. READ MORE
