7. Insights into the Evolution of Moth Pheromone Communication: Lessons from the European Corn Borer
Sammanfattning : Chemical communication by means of sex pheromones is central to the mating systems of a wide range of organisms. Because reproductive isolation is often based on pheromone differences, understanding how pheromones diverge is necessary for a complete comprehension of the speciation process. LÄS MER
8. Pre- and post-copulatory sexual selection in the fowl, Gallus gallus
