Actinopterygii (ray‐finned fishes) and E lasmobranchii (sharks, skates and rays) represent
more than half of today's vertebrate taxic diversity (approximately 33000 species) and form …

Background Fish classifications, as those of most other taxonomic groups, are being
transformed drastically as new molecular phylogenies provide support for natural groups …

The bony-tongue fishes, Osteoglossomorpha, have been the focus of a great deal of
morphological, systematic, and evolutionary study, due in part to their basal position among …

Classification of the tremendous diversity of ray-finned fishes (Actinopterygii) began with the
designation of taxonomic groups on the basis of morphological similarity. Starting in the late …

There is ongoing debate as to whether fish body size will decrease with global warming and
how these changes may impact dispersal ability and speciation rate. Theory predicts that …

One of the most remarkable types of migration found in animals is diadromy, a life-history
behaviour in which individuals move between oceans and freshwater habitats for feeding …

Migration independently evolved numerous times in animals, with a myriad of ecological
and evolutionary implications. In fishes, perhaps the most extreme form of migration is …

The Clupeiformes, including among others herrings, anchovies, shads and menhadens are
ecologically and commercially important, yet their phylogenetic relationships are still …

Abstract Aim The South American fish fauna is renowned for its extraordinary diversity. The
majority of this diversity is restricted to few major clades that have ancient associations to …

Biotic and abiotic forces govern the evolution of trophic niches, which profoundly impact
ecological and evolutionary processes and aspects of species biology. Herbivory is a …
