The Tree of Life and a New Classification of Bony Fishes
- Ricardo Betancur-R, R. Broughton, +21 authors G. Ortí
- Biology, Medicine
- PLoS currents
- 18 April 2013
The tree of life of fishes is in a state of flux because we still lack a comprehensive phylogeny that includes all major groups. The situation is most critical for a large clade of spiny-finned… Expand
Phylogenetic classification of bony fishes
- R. Betancur-R, E. Wiley, +5 authors G. Ortí
- Biology, Medicine
- BMC Evolutionary Biology
- 6 July 2017
BackgroundFish classifications, as those of most other taxonomic groups, are being transformed drastically as new molecular phylogenies provide support for natural groups that were unanticipated by… Expand
Morphology, Taxonomy, and Phylogeny of Triassic Pholidophorid Fishes (Actinopterygii, Teleostei)
- G. Arratia
- Biology
- 1 November 2013
ABSTRACT
This study presents the first comprehensive revision of ‘pholidophoriform’ fishes, which are a key taxon for understanding the early diversification of teleost fish. Systematic revisions… Expand
Vertebral column and associated elements in dipnoans and comparison with other fishes: Development and homology
- G. Arratia, H. Schultze, J. Casciotta
- Biology, Medicine
- Journal of morphology
- 1 November 2001
A vertebral column consisting of a persistent notochord and ossified arcocentra is the primitive condition for Gnathostomata; it still persists in primitive actinopterygians and sarcopterygians.… Expand
Multi-locus phylogenetic analysis reveals the pattern and tempo of bony fish evolution
- R. Broughton, Ricardo Betancur-R, C. Li, G. Arratia, G. Ortí
- Medicine, Biology
- PLoS currents
- 16 April 2013
Over half of all vertebrates are “fishes”, which exhibit enormous diversity in morphology, physiology, behavior, reproductive biology, and ecology. Investigation of fundamental areas of vertebrate… Expand
Jaws and teeth of american cichlids (Pisces: Labroidei)
- J. Casciotta, G. Arratia
- Biology, Medicine
- Journal of morphology
- 1 July 1993
The morphology of the upper, lower, and pharyngeal jaws is very similar among American cichlids. Common conditions are: (1) the presence of a premaxillary dentigerous arm shorter than the ascending… Expand
Development and diversity of the suspensorium of trichomycterids and comparison with loricarioids (Teleostei: Siluriformes)
- G. Arratia
- Biology, Medicine
- Journal of morphology
- 1 August 1990
Studies of ontogenetic series of trichomycterids and other catfishes reveal that the suspensorium of siluroids is highly specialized; several synapomorphies separate siluroids from other teleosts. In… Expand
Identifying patterns of diversity of the actinopterygian fulcra
- G. Arratia
- Biology
- 1 May 2009
Arratia, G. 2009. Identifying patterns of diversity of the actinopterygian fulcra. — Acta Zoologica (Stockholm) 90 (Suppl. 1): 220‐235 Fin rays, scutes or ridge scales, and fulcra have been… Expand
