Species diversity and phylogenetic systematics of American knifefishes (Gymnotiformes, Teleostei).

Balancing hydropower and biodiversity in the Amazon, Congo, and Mekong
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

The figures suggest that the conservation status of South American freshwater fish faunas is better than in most other regions of the world, but the marine fishes are as threatened as elsewhere. Expand
Major Biogeographic and Phylogenetic Patterns
Miocene tectonism and the separation of cis- and trans-Andean river basins: Evidence from Neotropical fishes
Among families of freshwater teleosts from northwestern South America, species diversity is significantly correlated with a minimum number of cis-/trans-Andean clades, which indicates that the relative species diversity and biogeographic distributions of Amazonian fishes were effectively modern by the late Middle Miocene.

Annelida and Arthropoda are Not Sister Taxa: A Phylogenetic Analysis of Spiralian Metazoan Morphology
This study presents a new analysis of 141 independently assembled characters, purported to represent the current state of knowledge of metazoan morphology and embryology, and results in robust support of the Eutrochozoa hypothesis. Expand
Miocene marine incursions and marine/freshwater transitions: Evidence from Neotropical fishes
It is speculated that unique ecological and biogeographic aspects of the Miocene upper Amazonian wetland system, most notably long-term connections with marine systems, facilitated the evolutionary transition from marine to freshwater habitats. Expand
Diversity and Phylogeny of Neotropical Electric Fishes (Gymnotiformes)
Phylogeny, biogeography, and electric signal evolution of Neotropical knifefishes of the genus Gymnotus (Osteichthyes: Gymnotidae).
- N. Lovejoy, Kristie Lester, W. Crampton, F. Marques, J. Albert
- Biology, Medicine
- Molecular phylogenetics and evolution
Phylogenetic optimization of electric signal waveforms indicate that the ancestral state in Gymnotus is a multiphasic (4+phases of alternating polarity) condition, and independent phase loss has occurred in multiple lineages. 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
