Miocene tectonism and the separation of cis- and trans-Andean river basins: Evidence from Neotropical fishes
- J. Albert, N. Lovejoy, W. Crampton
- Biology
- 1 March 2006
The fish fauna of trans-Andean river basins in northwestern South America is ancient and diverse, including 14% (558 of 4,085) of all Neotropical teleost species and representing 88% of the orders… Expand
Miocene marine incursions and marine/freshwater transitions: Evidence from Neotropical fishes
- N. Lovejoy, J. Albert, W. Crampton
- Biology
- 1 March 2006
Abstract Amazonian rivers contain a remarkable fauna of endemic species derived from taxa that generally occur in oceans and seas. Several hypotheses have been proposed to explain the origin of… Expand

The Neotropical knifefish genus Gymnotus is the most broadly distributed and the most diverse (34+species) gymnotiform genus. Its wide range includes both Central and South American drainages,… Expand
Effects of anoxia on the distribution, respiratory strategies and electric signal diversity of gymnotiform fishes
- W. Crampton
- Biology

This paper explores the relationship between dissolved oxygen concentration and the distribu- tion and electric signal diversity of 64 species of gymnotiforms from the Teferegion of the upper Amazon… Expand
Sexual Signal Evolution Outpaces Ecological Divergence during Electric Fish Species Radiation
- M. Arnegard, P. McIntyre, +6 authors C. Hopkins
- Biology, Medicine
- The American Naturalist
- 23 July 2010
Natural selection arising from resource competition and environmental heterogeneity can drive adaptive radiation. Ecological opportunity facilitates this process, resulting in rapid divergence of… Expand
Phylogenetic systematics and historical biogeography of the Neotropical electric fish Gymnotus (Teleostei: Gymnotidae)
- J. Albert, W. Crampton, D. Thorsen, N. Lovejoy
- Biology
- 1 April 2005
Abstract Phylogenetic interrelationships of the Neotropical electric fish genus Gymnotus are documented from comparative study of phenotypic data. A data matrix was compiled of 113 phenotypic… Expand
