A phylogenetic analysis of the major groups of catfishes (Teleostei: Siluriformes) using rag1 and rag2 nuclear gene sequences.
TLDR
Higher-level relationships among catfishes were investigated by parsimony, maximum likelihood and Bayesian analyses of two nuclear genes across 110 catfish species representing 36 of 37 families and Conorhynchos, confirming monophyly of Siluriformes, of most siluriform families and of a number of multifamily groups.

Balancing hydropower and biodiversity in the Amazon, Congo, and Mekong
TLDR
To achieve true sustainability, assessments of new projects must go beyond local impacts by accounting for synergies with existing dams, as well as land cover changes and likely climatic shifts, and call for more sophisticated and holistic hydropower planning. Expand
Molecular systematics of the African electric fishes (Mormyroidea: teleostei) and a model for the evolution of their electric organs.
TLDR
A reconstruction of electrocyte evolution on the basis of the best-supported topology suggests that electrocytes with penetrating stalks evolved once early in the history of the mormyrids followed by multiple paedomorphic reversals to electrocyces with non-penetrating stalks. Expand
A comprehensive multilocus phylogeny for the wood-warblers and a revised classification of the Parulidae (Aves).
TLDR
A summary phylogenetic hypothesis is provided that will be broadly applicable to investigations of the historical biogeography, processes of diversification, and evolution of trait variation in this well studied avian group. Expand
Discovery of African roots for the Mesoamerican Chiapas catfish, Lacantunia enigmatica, requires an ancient intercontinental passage
TLDR
Fossil-calibrated, relaxed-clock molecular analyses estimate lacantuniid divergence between 75 to 94 mya, after separation of Africa and South America, and find that Lacantunia is derived from within a multi–family clade of African freshwater catfishes. Expand
Simultaneous analysis of five molecular markers provides a well-supported phylogenetic hypothesis for the living bony-tongue fishes (Osteoglossomorpha: Teleostei).
TLDR
Maximum parsimony analysis of combined and equally weighted characters from the five molecular markers and Bayesian analysis provide a single, well-supported, hypothesis of osteoglossomorph interrelationships and show the group to be monophyletic. Expand
Phylogenetic relationships of the mockingbirds and thrashers (Aves: Mimidae).
TLDR
Re reconstructions based on mitochondrial and nuclear DNA sequence markers show that an early bifurcation separated the Mimidae into two clades, the first of which includes North and Middle American taxa plus a small radiation that likely occurred largely within the West Indies and the Toxostoma thrasher clade. Expand
Sexual Signal Evolution Outpaces Ecological Divergence during Electric Fish Species Radiation
Natural selection arising from resource competition and environmental heterogeneity can drive adaptive radiation. Ecological opportunity facilitates this process, resulting in rapid divergence ofExpand
DISCOVERY AND PHYLOGENETIC ANALYSIS OF A RIVERINE SPECIES FLOCK OF AFRICAN ELECTRIC FISHES (MORMYRIDAE: TELEOSTEI)
TLDR
A species flock of riverine mormyrid fishes from west‐central Africa is described in which electric signals may play a role in the reproductive isolation of sympatric species and selection on EOD waveforms as mate recognition signals may be involved in the radiation of these fishes. Expand
Redescription of Orthosternarchus tamandua (Boulenger, 1898) (Gymnotiformes, Apteronotidae), with reviews of its ecology, electric organ discharges, external morphology, osteology, and phylogenetic
TLDR
This paper redescribes the apteronotid fish Orthosternarchus tamandua, the only species of its genus, and describes and illustrates the osteology of O. tamandUA, and clarifies many aspects of its skeleton. Expand
