The Chromosomal Phylogeny of Owls (Strigiformes) and New Karyotypes of Seven Species
The phylogeny of 33 owl species is studied karyologically and seven owl species new to karyology are described.
Phylogenetic relationships in the bovid subfamily Antilopinae based on mitochondrial DNA sequences.
The tribe Antilopini is monophyletic with Antidorcas marsupialis and Litocranius walleri basal to the large genus Gazella, which would either make Gazella paraphyletic or require that the genus name Gazella be changed to Antilope.
The chromosomes of Gazella bennetti and Gazella saudiya
Seven individuals of captive Gazella bennetti were found to have chromosomal complements of 2n = 49-52, and seven captive G. saudiya had complements that revealed variation in diploid number was the result of an autosome-to-X chromosome translocation and four independent Robertsonian translocations.
Molecular genetics of endangered species
A brief discussion of definitions of species and their population subdivisions, the genetic costs and risks associated with conservation programmes focused on systematic divisions below the species level, and the use of molecular techniques to reveal taxonomic units are included.
Saudi gazelle (Gazella saudiya) is not a subspecies of Dorcas gazelle
The karyotypes of Saudi gazelle presented here vary in the numbers of metacentric chromosomes, but the cause of this variation is not yet known.
Cytochrome b Sequences from the Endangered Saudi Gazelle (Gazella Saudiya) Suggest Hybridization with Chinkara (G. bennetti)
The historical range of the now endangered Saudi gazelle ( Gazella saudiya ) is considered to have extended throughout the Arabian peninsula from Yemen to Iraq and Kuwait (Carruthers & Schwarz 1935;…
