The Chirostoma "humboldtianum" group includes seven silverside species considered as a monophyletic assemblage because of their high genetic and morphological similarities. The group includes five moderately large species, "peces blancos" (117-300 mm standard length--SL) and two smaller species, "charales" (70-142 mm SL). These species are of great economical, cultural and ichthyological intere...

Morphology has been the subject of several studies in Eunice specially in the context of the taxonomy and evolutionary relationships of taxa within this genus. In this study we opt for a morphometric approach comparing five species of Eunice to assess if it was possible to delimitate them by shape variables. The morphology of E. fucata, E. insularis, E. cf. ornata, E. rubra, and Eunice sp. was ...

Although many of the goals and concepts of qualitative morphological analysis and morphometrics are similar, systematists have largely rejected the use of morphometric methods in phylogenetic analysis on a variety of grounds. This review finds that (1) the concepts of a cladistic character and a morphometric variable are essentially identical, (2) morphometric methods can be instrumental in dis...

The aim of this exploratory study was to explore impact of organized physical activities on the latent structure of some morpho-functional variables. Discrimination between group of athletes (167 entities, aged 22.4 years) and group of non-athletes (150 entities, aged 25.7 years) has been explored in latent structure of 12 morphometric variables, 4 physiological variables and 7 hematological va...

In 65 patients with primary invasive ductal breast carcinoma the relation between classic prognosticators describing the extent of disease (lymph node metastases and tumour size) and newer promising morphometric and DNA flow cytometric prognostic factors was studied. There was no relation between DNA ploidy, lymph node state, and tumour size. Tumours with a mitotic activity index of more than 1...
