Folkbiology of freshwater fish
Cognition, 2006Cross-cultural comparisons of categorization often confound cultural factors with expertise. This paper reports four experiments on the conceptual behavior of Native American and majority-culture fish experts. The two groups live in the same general area and engage in essentially the same set of fishing-related behaviors.

Speciation in Freshwater Fishes
Annual Review of Ecology, Evolution, and Systematics, 2014The extraordinary species richness of freshwater fishes has attracted much research on mechanisms and modes of speciation. We here review research on speciation in freshwater fishes in light of speciation theory, and place this in a context of broad-scale diversity patterns in freshwater fishes.

Freshwater fishes of northern Australia
Zootaxa, 2017Northern Australia is biologically diverse and of national and global conservation signicance. Its ancient landscape contains the world’s largest area of savannah ecosystem in good ecological condition and its rivers are largely free-flowing. Agriculture, previously confined largely to open range-land grazing, is set to expand in extent and to focus ...

DNA barcoding Indian freshwater fishes
Mitochondrial DNA Part A, 2015DNA barcoding is a promising technique for species identification using a short mitochondrial DNA sequence of cytochrome c oxidase I (COI) gene. In the present study, DNA barcodes were generated from 72 species of freshwater fish covering the Orders Cypriniformes, Siluriformes, Perciformes, Synbranchiformes, and Osteoglossiformes representing 50 genera

As stressed in chapter III, Tasmania possesses both an abundance of fresh water and a diversity of freshwater environments. Nevertheless, the native freshwater fish fauna is relatively small and it is also unbalanced in composition. There are about twenty-three species of native fish which are commonly found in fresh water or are dependent on it for ...

Abstract This chapter focuses on cold adaptation in freshwater fish, and especially how predicted climate change may alter the winter environment and conditions in streams and lakes, and how selected freshwater fish are likely to respond. Consequently, geographical research is restricted to high latitude regions in northern North America ...

Geriatric Freshwater and Marine Fish
Veterinary Clinics of North America: Exotic Animal Practice, 2020As pain management finally becomes accepted for this last of the vertebrate taxa, fish medicine is finally reaching the sophistication of other vertebrates. The diseases of aging fish in captivity therefore need to be addressed. The degenerative organ/tissue changes and neoplasias of fish deserve the same diagnosis and treatments of their terrestrial ...

New Zealand has a small freshwater fish fauna, by any standard of comparison. A precise enumeration is not yet possible as some taxonomic problems remain to be resolved, but there are about 30 native species. Eight families are represented, none of which is endemic.
