Phylogeny and DNA-DNA hybridization.
Resolving the phylogeny of the hominoid primates is a test case for molecular systematic methods because, by most genetic measures, humans, chimpanzees, and gorillas are very closely related. Recently, Sibley and Ahlquist (1984) applied DNADNA hybridization techniques to infer the hominoid phylogenetic tree with humans and chimpanzees closest. Templeton (1983, 1985) argues rather that the chimp...
متن کاملSKUA – retrofitting semantics
The Semantic Web promises much for software developers, but because its claimed benefits are rather abstract, there is little obvious incentive to master its unfamiliar technology. In contrast, many ‘Social Web’ applications seem rather trivial, and not obviously useful for astronomy. The SKUA project (Semantic Knowledge Underpinning Astronomy) is implementing a service which will realise the b...
متن کاملPredation on burrowing petrels by the brown skua (Catharacta skua loÈnnbergi) at Mayes Island, Kerguelen
The diet of the brown skua (Catharacta skua loÈnnbergi) was studied at Mayes Island, Kerguelen archipelago, by collection of prey remains on 11 territories during the complete breeding cycle of the species there. In nine territories, collections were daily or every two days for a quantitative investigation of the diet. The blue petrel (Halobaena caerulea) and thin-billed prion (Pachyptila belch...
متن کاملPhylogeny and taxonomy of mesophilic Methanococcus spp. and comparison of rRNA, DNA hybridization, and phenotypic methods.
The phylogeny and taxonomy of the mesophilic methane-producing archaea of the order Methanococcales were examined by DNA relatedness, 16S rRNA sequence analysis, cellular protein patterns, and phenotypic methods. The mesophilic species Methanococcus maripaludis, Methanococcus vannielii, Methanococcus voltaei, and "Methanococcus aeolicus" formed a deep group with 5 to 30% DNA relatedness and 92 ...
متن کاملThe platypus is not a rodent: DNA hybridization, amniote phylogeny and the palimpsest theory.
We present DNA-hybridization data on 21 amniotes and two anurans showing that discrimination is obtained among most of these at the class and lower levels. Trees generated from these data largely agree with conventional views, for example in not associating birds and mammals. However, the sister relationships found here of the monotremes to marsupials, and of turtles to the alligator, are surpr...
