The repeated adaptation of oceanic threespine sticklebacks to fresh water has made it a
premier organism to study parallel evolution. These small fish have multiple distinct …

Members of the Diplostomoidea mature in amniotes and employ vertebrates, annelids and
molluscs as second intermediate hosts. Diplostomoid life cycles generally follow a three …

Tapeworms (Cestoda) represents a species rich (about 5000 species) group of flatworms
(Neodermata) parasitizing all groups of vertebrates including humans, with about 1000 …

Hamilton and Zuk proposed a good-genes model of sexual selection in which genetic
variation can be maintained when females prefer ornaments that indicate resistance to …

Altered thermal regimes associated with climate change are impacting significantly on the
physical, chemical, and biological characteristics of the Earth's natural ecosystems, with …

Thanks to high species diversity and a broad range of speciation mechanisms, cichlid fishes
represent a textbook model in evolutionary biology. They are also of substantial economic …

Recent research provides accumulating evidence that the evolutionary dynamics of host–
parasite adaptations strongly depend on environmental variation. In this context, the three …

Gnotobiotic models have had a crucial role in studying the effect that commensal microbiota
has on the health of their animal hosts. Despite their physiological and ecological diversity …

It is well established that parasites can have profound effects on the behaviour of host
organisms, and that individual differences in behaviour can influence susceptibility to …

Global expansion in fish production and trade of aquatic ornamental species requires
advances in aquatic animal health management. Aquatic parasite cultures permit diverse …
