  author={Kory M Evans and William G. R. Crampton and James S. Albert},
  journal={Neotropical Ichthyology},
This paper provides a taxonomic revision of the Neotropical electric fish genus Sternarchella, with redescriptions of seven valid species and descriptions of two new species. A maximum parsimony analysis of 76 morphological characters from seven ingroup and seven outgroup taxa recovered a non-monophyletic Sternarchella, in which a clade comprising two species with a ventral mouth (S. orinoco + S. sima) is the sister group to a clade comprising seven species that possess a terminal or superior… Expand
Molecular phylogeny of the ghost knifefishes (Gymnotiformes: Apteronotidae).
This work presents a phylogenetic hypothesis based on molecular sequence data from three mitochondrial genes (16S, coi, cytb) and four nuclear loci that corroborate previous phylogenetic hypotheses with the placement of Orthosternarchus+ Sternarchorhamphus sister to all other apteronotids, a non-monophyletic Apterontotus, and a sister relationship between Stern Archorhynchus and the Navajini.

Checklist of the freshwater fishes of Colombia: a Darwin Core alternative to the updating problem
Updating the current checklist is a fundamental requirement to ensure its incorporation in the decision-making process with regard to the conservation of Colombian aquatic species and ecosystems, which are facing transformation processes as a result of activities such as mining, construction of hydroelectric plants, expansion of the agricultural frontier and subsequent deforestation.

Specialized specialists and the narrow niche fallacy: a tale of scale-feeding fishes
A stark contrast is recovered between the feeding morphology of scale-feeding and non-scale-feeding taxa, with lepidophagous fishes displaying some paedomorphic characters through to adulthood. Expand
Checklist of the ichthyofauna of Mamirauá Sustainable Development Reserve, Middle Solimões, Amazonas, Brazil: high richness in a large protected area of Western-Central Amazonia
Abstract: The present study reviews the records of occurrences of fish species found in the Mamirauá Sustainable Development Reserve (MSDR). The reserve is located in a large section of the middleExpand
Bony Patchwork: Mosaic Patterns of Evolution in the Skull of Electric Fishes (Apteronotidae: Gymnotiformes).
This work constructs a time-calibrated phylogeny for a clade of Neotropical electric fishes and uses three-dimensional geometric morphometrics to investigate patterns of mosaic evolution in the skull and jaws and finds strong support for a developmental, three-module hypothesis that consists of the face, braincase, and mandible. Expand
Ecomorphology of Neotropical Electric Fishes: An Integrative Approach to Testing the Relationships between Form, Function, and Trophic Ecology
The results indicate that selection is driving the evolution of mandible shape and performance toward specialization on different trophic ecologies in riverine-adapted electric fishes from a region with high seasonal variability; the Amazon River. Expand
The changing course of the Amazon River in the Neogene: center stage for Neotropical diversification
The origins of the modern Amazon River are hypothesized to be linked with that of mega-wetland landscapes of tropical South America, which have persisted over about 10% northern South America under different configurations for >15 million years. Expand


Magosternarchus, a New Genus with Two New Species of Electric Fishes (Gymnotiformes: Apteronotidae) from the Amazon River Basin, South America
A new group of predaceous apteronotid electric fishes is described from recent trawl collections made in large, white- and black-water river channels of the Amazon Basin in Brazil and shared features of the ethmoid and jaw bones, mesopterygoid, opercle, gillrakers, basibranchials, and infraorbital laterosensory canal suggest that Magosternarchus is most closely related to Sternarchella.

Sternarchella calhamazon n. sp., the Amazon's Most Abundant Species of Apteronotid Electric Fish, with a Note on the Taxonomic Status of Sternarchus capanemae Steindachner, 1868 (Gymnotiformes, Apteronotidae)
A new species of apteronotid electric fish is described from the Brazilian and Peruvian Amazon that conspicuously differs from its congeners in caudal peduncle shape, electric organ size and shape, hemal spine elongation above the anal fin, and arrangement of intermuscular bones adjacent to the electric organ.

A new species of electric knifefish, genus Compsaraia (Gymnotiformes: Apteronotidae) from the Amazon River, with extreme sexual dimorphism in snout and jaw length
The genus Compsaraia represents one of at least three phylogenetically independent cases of snout elongation and at least four cases of jaw elongation within the Apteronotidae, and suggests the influence of both sexual and trophic functional influences on the evolution of head morphology. Expand

Evolutionary convergence of body shape and trophic morphology in cichlids from Lake Tanganyika
It is hypothesized that trophic ecology may be a key factor promoting morphological differentiation, and postulate that similar body shape and feeding structures have evolved multiple times in independent lineages, enabling taxa to invade similar adaptive zones. Expand
