The Limbs of Lepidosiren Paradoxa [PDF]
Nature, 1894 DR. GUNTHER, in his valuable work, “The Study of Fishes,” says of Natterer's Lepidosiren from the Amazons, “It is one of the greatest desiderata of natural history collections.” In fact, only seven years ago the opinion was current that Natterer had been deceived by specimens of Protopterus imported from Africa, or that in some way African specimens ...

RNA‐Mediated Gene Duplication and Retroposons: Retrogenes, LINEs, SINEs, and Sequence Specificity
International Journal of Evolutionary Biology, Volume 2013, Issue 1, 2013., 2013 A substantial number of “retrogenes” that are derived from the mRNA of various intron‐containing genes have been reported. A class of mammalian retroposons, long interspersed element‐1 (LINE1, L1), has been shown to be involved in the reverse transcription of retrogenes (or processed pseudogenes) and non‐autonomous short interspersed elements (SINEs ...

Bony fish genomes: Status and gaps
Journal of Fish Biology, EarlyView.Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Respiratory Properties of Blood and Pattern of Gas Exchange in the Lungfish Neoceratodus forsteri (Krefft) [PDF]
, 1966 Blood respiratory properties and gas exchange patterns have been studied in the lungfish Neoceratodus. O2 - Hb dissociation curve reveals a high affinity for O2 (P50 of 11 mm Hg at PCO2 3.5 mm Hg).
