Tempo and Mode of Diversification in the Neotropical Fish Superfamily Anostomoidea (Ostariophysi : Characiformes)
Neotropical characiform fishes form one of the most diverse freshwater ichthyofauna in the world. Knowledge of evolutionary processes that generated and maintain the immense characiform lineage and morphological diversity is still poorly understood. When did characiform lineages diversify? How have major geological and environmental changes affected diversification? Why are some clades seemingly more morphologically diverse than others? I examine the characiform superfamily Anostomoidea to address these broader questions of Neotropical diversification. The abundant Neotropical freshwater fish superfamily Anostomoidea contains two clades with seemingly disparate evolutionary strategies. The f...
Checklist of Marine and Estuarine Fishes from the Alaska-Yukon Border, Beaufort Sea, to Cabo San Lucas, Mexico
"Abstract: This paper is a checklist of the fishes that have been documented, through both published and unpublished sources, in marine and estuarine waters, and out 200 miles, from the United States-Canadian border on the Beaufort Sea to Cabo San Lucas, Mexico. A minimum of 241 families and 1,644 species are known within this range, including both native and nonnative species. For each of these species, we include maximum size, geographic and depth ranges, whether it is native or nonnative, as well as a brief mention of any taxonomic issues. Keywords: eastern North Pacific Ocean, taxonomy, species, inventory"--Page 7.

Fishes of the Salish Sea
Fishes of the Salish Sea is the definitive guide to the identification and history of the marine and anadromous fishes of Puget Sound and the Straits of Georgia and Juan de Fuca. This comprehensive three-volume set, featuring striking illustrations of the Salish Sea's 260 fish species by noted illustrator Joseph Tomelleri, details the ecology and life history of each species and recounts the region's rich heritage of marine research and exploration. Beginning with jawless hagfishes and lampreys and ending with the distinctive Ocean Sunfish, leading scientists Theodore Wells Pietsch and James Orr present the taxa in phylogenetic order, based on classifications that reflect the most current sc...
