6. Genetic response to pollution in sticklebacks; natural selection in the wild
Sammanfattning : The last century, humans have been altering almost all natural environments at an accelerating rate, including the Baltic Sea that has highly eutrophicated areas and many coastal industries such as Pulp-mills. For animals living in a habitat that changes there are basically two alternatives, either to cope with the change or become locally extinct. LÄS MER
7. Morphological and functional effects of insulin signaling and the bHLH transcription factor Dimmed on different neuron types in Drosophila
Sammanfattning : In Drosophila, the insulin signaling pathway is at the interface between dietary conditions and control of growth and development, reproduction, stress responses and life span. Eight insulin like peptides (Dilp1-8), an insulin tyrosine kinase receptor (dInR) and its downstream components, as well as a relaxin-like receptor type (Lgr3) form the core of this signaling.

8. Regulation of insulin signaling and its developmental and functional roles on peptidergic neurons in the Drosophila central nervous system
Sammanfattning : In Drosophila, eight insulin-like peptides (DILP1-8) are produced and secreted in different locations. They regulate many aspects of development and physiology, such as organism growth, metabolic homeostasis, reproduction, stress resistance and life span. LÄS MER
9. The sensory morphology of insect pollinators : From structure to behaviour and ecology
Sammanfattning : Insect pollinators play an important role in balancing our ecosystems and maintaining plant and food diversity. Due to anthropogenic activities such as global warming, habitat loss and degradation, pesticides, and pathogens, many pollinator populations have been undergoing drastic declines in recent decades.

10. Reproductive physiology of the female three-spined stickleback, Gasterosteus aculeatus
Sammanfattning : Reproduction in vertebrates, including fishes, is under control of the brain-pituitary-gonad (BPG) axis. The female three-spined stickleback, Gasterosteus aculeatus, produces egg clutches at intervals of a few days and spawns them in a nest built by male. LÄS MER
