    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; female choice; filial cannibalism; Gobiidae; parental care; Pomatoschistus minutus; sand goby; sexual conflict; sexual selection; Biology; Biologi;

    Sammanfattning : Natural and sexual selection and sexual conflict are forces shaping the evolution of reproductive behaviour, while constrained by factors like environment, physiology and life-history trade-offs. Parental care is costly both in terms of time and energy. LÄS MER

    Sammanfattning : I investigated the ecology and population density of the sand goby, Pomatoschistus minutus, at sub-thermocline depth in the north-western Baltic proper. Most previous research on the sand goby, and the co-occurring closely related common goby, P. LÄS MER

  7. 5. Reproductive traits in euryhaline gobies: insights into physiology, adaptations and biological invasions

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

    Sammanfattning : 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. LÄS MER
