1. Brain Aromatase in the guppy, Poecilia reticulata : Distribution, control and role in behaviour
Sammanfattning : Oestrogens are produced by aromatisation of androgens by the aromatase enzyme. In the vertebrate brain this synthesis has vital functions in nerve protection, cell proliferation and nerve development during injury respectively brain development. LÄS MER
2. Neuroestrogen and male reproductive behaviour in the guppy
Sammanfattning : .... LÄS MER
3. Brain morphology and behaviour in the guppy (Poecilia reticulata) : Effects of plasticity and mosaic brain evolution
Sammanfattning : Understanding how brains have evolved and subsequently culminated in the huge variation in brain morphology among contemporary vertebrate species has fascinated researchers for many decades. It has been recognized that brain morphology is both genetically and environmentally determined. LÄS MER
4. The link between brain size, cognitive ability, mate choice and sexual behaviour in the guppy (Poecilia reticulata)
Sammanfattning : Competition over access for mates has led to the evolution of many striking examples of morphological traits and behaviour in animals. The rapid development of the sexual selection field in recent decades have dramatically advanced our understanding of what traits make individuals more successful in attracting mates and how preferences for mates evolve over time. LÄS MER
5. A comparison of the magnitudes of genetic variation of some quantitative characters in salmon (Salmo salar L.) and guppy (Lebistes reticulatus)
Sammanfattning : .... LÄS MER
