The validity of taxa around Microsporum canis was evaluated by a combination of phenetic and molecular methods. Morphological and physiological features were compared with results of sequencing of the internal transcribed spacer (ITS) region of the ribosomal operon, polymerase chain reaction (PCR) fingerprinting and amplified fragment length polymorphism (AFLP) analysis. The seven species inves...

Taxa in the Banksia spinulosa Sm. complex (Proteaceae) have populations with sympatric, parapatric and allopatric distributions and unclear or disputed boundaries. Our hypothesis is that under biological, phenetic and diagnosable species concepts that each of the currently named taxa within the Banksia spinulosa complex is a separate species. Based on specimens collected as part of this study, ...

An AFLP data set comprising 95 accessions from 20 species of Lactuca s.l. (sensu lato) and related genera was generated using the primer combinations E35/M48 and E35/M49. In phenetic analyses of a data subset, clustering with UPGMA based on Jaccard's similarity coefficient resulted in the highest cophenetic correlation, and the results were comparable to those of a principal coordinates analysi...

A bacterial strain, DC-186(T), isolated from home-made compost, was characterized for its phenotypic and phylogenetic properties. The isolate was a Gram-negative rod that was able to grow at 15-36 degrees C and pH 5.5-8.0. Strain DC-186(T) was positive in tests for catalase, oxidase and beta-galactosidase activities and aesculin hydrolysis. The predominant fatty acids were the summed feature C(...

Parsimony analysis of characters derived from an electrophoretic survey of allozyme variation in the sceloporine sand lizards indicates that Uma is outside of a clade formed by the rest of the sand Uzards and that Cophosaurus and Holbrookia share a more recent common ancestor with one another than either does with Callisaurus. Previous electrophoretic studies used phenetic clustering based on g...
