Identification of a female sex pheromone in Carcinus maenas
Despite major progress in our understanding of animal signaling systems, the identification of chemical signals in aquatic organisms is still in its infancy. Exemplary for this is the lack of structural knowledge of crustacean sex pheromones despite their initial description in crabs almost 40 yr ago. We hypothesized that species in which the reproductive event is linked to a short window of ma...
متن کاملIntraspecific Variation in Female Sex Pheromone of
The codling moth, Cydia pomonella L. (Lepidoptera, Tortricidae), is a major pest of apple, pear and walnut orchards worldwide. This pest is often controlled using the biologically friendly control method known as pheromone-based mating disruption. Mating disruption likely exerts selection on the sexual communication system of codling moth, as male and female moths will persist in their attempt ...
متن کاملA kinetic study of muscle pyruvate kinase from Carcinus maenas.
mantle coincided with the time when the greatest shell shoot was measured (Table 1, day 40). Our results support the view that, at least in mantle tissue, there is a direct correlation between shell formation and carbonic anhydrase activity. A major function of the gill is gaseous exchange, and the fact that gill carbonic anhydrase activity follows a similar pattern of change to that of new she...
متن کاملAsymmetry and fighting performance in the shore crab Carcinus maenas.
Fluctuating asymmetries (left-right differences in symmetric traits) can be negatively related to fitness parameters in a number of biological systems. Hence, it has been suggested that symmetric individuals should outcompete asymmetric individuals during intraspecific agonistic encounters. However, there is a lack of experimental evidence for such a relationship. We investigated the relationsh...
متن کاملAgonistic behaviour and biogenic amines in shore crabs Carcinus maenas.
To investigate the role of certain neurohormones in agonistic behaviour, fights were staged between pairs of size-matched male shore crabs Carcinus maenas, and blood samples were taken immediately after the contests had been resolved. Samples were also taken from these crabs at rest (before and after fighting) and after walking on a treadmill. A control group of crabs also had samples taken on ...
