Geographic meristic variation in Diplophos taenia Günther (Salmoniformes: Gonostomatidae)

Deep Sea Research and Oceanographic Abstracts, 1972
Abstract Examination of over 500 specimens of the mesopelagic gonostomatid fish Diplophos taenia Gunther revealed a striking but puzzling variability in central tendency of longitudinally arranged meristic characters. Attempts at correlation of this variation with various physical and biological oceanographic parameters revealed a highly ...

Epidermal fine structure of the teleost Esox americanus (esocidae, salmoniformes)

Journal of Ultrastructure Research, 1974
The epidermis of Esox americanus consists of filament-containing cells, secretory cells, and occasional chloride cells. The filament-containing cells are the most numerous with three distinct types belonging to basal, mid and surface layers. These cells have predominately a structural role, although the surface cells probably contribute to the ...

Spawning ofGalaxias fasciatusGray (Salmoniformes: Galaxiidae)

New Zealand Journal of Marine and Freshwater Research, 1982
Abstract For the first time Galaxias fasciatus Gray were observed spawning. The spawning sites were among flooded terrestrial vegetation along the margins of a stream during the peak of a flood. Spawning appeared to be a communal event and the fish were vulnerable to eel (Anguilla dieffenbachii) predation at the time.

Revalidation and redescription of Brachymystax tsinlingensis Li, 1966 (Salmoniformes: Salmonidae) from China

Zootaxa, 2015
Brachymystax tsinlingensis Li, 1966 is revalidated and redescribed. It can be distinguished from all congeners by the following combination of characteristics: no spots on operculum; gill rakers 15-20; lateral-line scales 98-116; pyloric caeca 60-71. Unique morphological characters and genetic divergence of this species are discussed.

Evolutionary Homoplasy among Species Flocks of Central Alpine Coregonus (Teleostei: Salmoniformes)

Copeia, 2005
Evolution of phenotype and mode of speciation were examined for 19 Coregonus populations within and among eight lakes in the Central Alpine region of Europe. These populations reflect a mosaic of morphological, ecological, and life history traits, and thus represent numerous forms (qualitatively described according to relative body size and ecology ...

A Revison of the Genus Paragalaxias Scott (Salmoniformes : Galaxiidae)

Australian Journal of Marine and Freshwater Research, 1978
Paragalaxias dissimilis (Regan), which has not been reported since description from 'New South Wales' in 1905, is shown to be a senior synonym of P. shannonensis Scott, 1935, from Great Lake, Tasmania. Two new species of Parugalaxias, one from Great Lake and another from Arthurs Lake nearby, are described.

Molecular phylogeny and biogeography of the Tasmanian and New Zealand mudfishes (Salmoniformes : Galaxiidae)

Australian Journal of Zoology, 1997
The phylogenetic affinities of the diadromous Tasmanian mudfish, Galaxias cleaveri , have long been problematic. Some systematists have suggested that this species is closely related to the morphologically similar but non-diadromous New Zealand mudfish genus, Neochanna , while others argued that the similarities represent convergent evolution.

Comparative morphometry and phenetics of the genera of esocoid fishes (Salmoniformes)

Zoological Journal of the Linnean Society, 1987
Using shape data derived from the externa] body morphometry of esocoid fishes in which the effects of size were standardized, a close relationship of Umbra and Novumbra is supported. Dallia is provisionally associated with these but some data contradicted this. Esox is distantly associated with all of these.
