Controversial Nature

Within Australia there are 19 endemic species of Anseriformes. Six of these belong to monotypic genera, some of which remain controversial with respect to phylogenetic relationships. Sequence variation in a 307-base pair fragment of the cytochrome-b gene was compared from 23 species of waterfowl (the Cairina sequence was obtained from the literature) to elucidate further the relationships of these monotypic Australian genera. Anseranas and Dendrocygna were identified as the earliest diverged genera among the taxa examined. The remaining genera fell into two groups: (1) Tadorna, Alopochen, Chenonetta, Anas, Aythya, Cairina and Air and (2) Cygnus, Branta, Cereopsis, Biziura, Oxyura, Malacorhynchus, Stictonetta and Nettapus. The controversial nature of the last group is discussed.

Pooled Sample

AbstractSequence variation of a 1066 bp long mtDNA fragment (cytochrome b gene, adjacent part of tRNA-Thr gene) of four known-locality samples of Testudo kleinmanni (Tripolitania, Libya) and of four samples of T. werneri (Negev, Israel) is compared with additional five sequences of pet trade tortoises allegedly representing T. kleinmanni. Four haplotypes, differing in one to four mutation steps occur. The most common haplotype was shared by all known-locality samples of T. kleinmanni and three T. werneri. Sequence variation within each nominal species and in the pooled sample of T. kleinmanni, T. werneri and pet trade tortoises is the lowest known for any Testudo species. We conclude there is no support for the validity of T. werneri Perälä, 2001.
