1. Neuromolecular and behavioural profile of teleosts : - effects of boldness, agonistic behaviour and reproductive status
Sammanfattning : This thesis investigates if boldness is reflected in the function of brain histaminergic system in zebrafish (Danio rerio). Moreover, behavioural differences in AB line, spiegeldanio (spd) line and wild caught strain of zebrafish have also been explored apart from the winner-loser effect in AB and spd fish. LÄS MER

4. Drosophila Sensory Neuroethology
Sammanfattning : Animals, like humans, need to perceive their surroundings via their senses in order to make sensible behavioral decisions, reproduce successfully, and survive. Animals are equipped with audition, vision, thermosensation, hygrosensation, mechanosensation, magnetoception, gustation, and olfaction, which detects physical and chemical changes in their habitats.

5. Behavioural, physiological and morphological correlates of life-history in killifishes − a macroevolutionary approach
Sammanfattning : Life-histories commonly evolve along a continuum from short-lived and fecund, to long-lived and less fecund. Because life-history traits are mostly components of reproduction and survival, understanding the causes and consequences of life-history variation is at the core of evolutionary biology. LÄS MER
