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 …

The marine‐freshwater boundary is a major biodiversity gradient and few groups have
colonised both systems successfully. Fishes have transitioned between habitats repeatedly …

The Afrotropics house a diverse freshwater ichthyofauna with> 3000 species, almost all of
which are endemic. Recent progress in dated phylogenetics and palaeontology of several …

Freshwater habitats make up only∼ 0.01% of available aquatic habitat and yet harbor 40%
of all fish species, whereas marine habitats comprise> 99% of available aquatic habitat and …

Habitat shifts are implicated as the cause of many vertebrate radiations, yet relatively few
empirical studies quantify patterns of diversification following colonization of new habitats in …

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 …

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 …

Adaptive radiations are typically triggered when a lineage encounters a significant range of
open niche space (ecological opportunity), stemming from colonisation of new areas …

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 …
