... ( Gasterosteus aculeatus ) sampled from four locations in northern Europe. We found that the male brain increased in size (ca. 24%) significantly more than the female brain towards breeding, and that the resulting brain SSD was similar (ca. 20%) for all populations over the breeding cycle. Our findings support...

... and threespine stickleback ( Gasterosteus aculeatus ) system, as this cestode can reach up to 92% of its fish host mass. Our results suggest that the mass burden brought by this macroparasite alone is not sufficient to cause behavioural changes in its host. Furthermore, our results show that wall-hugging...

... ). Our aim was to test whether any of the host­-response, side effect or direct manipulation hypotheses could explain the suite of behavioural changes triggered by the internal cestode parasite, Schistocephalus solidus Müller 1776, in its threespine stickleback host ( Gasterosteus aculeatus Linnaeus...

...Matthew D. McGee; Peter C. Wainwright SUMMARY Sexual dimorphism is common in nature and has the potential to increase intraspecific variation in performance and patterns of resource use. We sought to determine whether anadromous threespine stickleback, Gasterosteus aculeatus , exhibit sexual...
