CLADOGENESIS AND LOSS OF THE MARINE LIFE-HISTORY PHASE IN FRESHWATER GALAXIID FISHES (OSMERIFORMES: GALAXIIDAE) [PDF]
Evolution, 2001 Switches from migratory (diadromous) to nonmigratory (freshwater) life histories are known to have occurred repeatedly in some aquatic taxa. However, the significance of the loss of diadromy as an initiator for speciation remains poorly understood. The rivers of New Zealand's South Island house a species flock of recently derived nonmigratory galaxiid ...

Global Patterns and Gaps in Research on Salinity Tolerance of Inland Fishes
Fish and Fisheries, Volume 27, Issue 2, Page 400-411, March 2026.ABSTRACT Freshwater salinization is an emerging threat impacting approximately one‐third of the world's freshwater bodies. However, the salinity tolerance of many inland fishes remains understudied, despite being a crucial factor in determining species distributions and fitness.

Mitochondrial DNA Part B, 2016 Complete mitochondrial genome sequences were determined for two lineages ("CEQ" and "SEQ") of the Australian smelt, Retropinna semoni. Both mitogenomes contain the typical vertebrate arrangement of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and control region.
