Fishes (Elasmobranchii and Actinopterygii) of Picãozinho reef, Northeastern Brazil, with notes on their conservation status

Zootaxa, 2007
Shallow reefs on the northeastern coast of Brazil are rich, productive and diverse environments, with great ecological and economical importance. Picãozinho is located 1,500 m off the coast of João Pessoa city, Paraíba state, NE Brazil. The aim of this work is to provide an updated list of the reef fishes of Picãozinho, based on a survey of ...

Stomach contents of the Early Jurassic fish †Lepidotes Agassiz, 1832 (Actinopterygii, Lepisosteiformes) and their palaeoecological implications

Historical Biology, 2019
Ginglymodian fishes formed one of the most dominant actinopterygian lineages during the Mesozoic, occurring in fully marine to freshwater depositional environments. However, although commonly preserved in Mesozoic strata around the world, there is little

Comparative Analysis of the Organization of the Catecholaminergic Systems in the Brain of Holostean Fishes (Actinopterygii/Neopterygii)

Brain, Behavior and Evolution, 2019
Living holosteans, comprising 8 species of bowfins and gars, form a small monophyletic group of actinopterygian fishes, which are currently considered as the sister group to the enormously numerous teleosts and have largely been neglected in neuroanatomical studies.

Ray-finned fishes (Actinopterygii)

2009
Abstract Actinopterygii, or ray-Anned Ashes, are one of the two major lineages of osteichthyan vertebrates, the other being Sarcopterygii (1). 7ere are more than 26,890 species of actinopterygian Ashes and the group has diversiAed into a wide range of marine and freshwater habitats (2).

Isozymes of soluble malate dehydrogenase (s-MDH) in fishes of the subclasses chondrichthyes and actinopterygii

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1990
Abstract 1. 1. A recopilation of species of fishes used for the study of s-MDH isozymes was made. 2. 2. s-MDH of most fishes was shown to be codified by two gene loci. However, there are fishes with a more complex pattern, with s-MDH composed of subunits codified in three or four gene loci. 3. 3.
