The analysis of morphology is crucial to the study of phylogeny in many ancient and modern organismal groups. Recently a number of arguments have been made in favor of regarding certain kinds of morphometric variables as putatively homologous characters and allowing them to participate, along with other non-morphometric variables, in parsimony-based cladistic analyses. These arguments rest on t...

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...

Objective- Postoperative pain management in patients that undergone arthroscopy is one of the most important procedures for their rehabilitation. Analgesic injection intra-articularly can facilitate pain control in such patients. The aim of this study was to evaluate the effects of ketamine on articular cartilage in rat model. Design- Experimental study. Animals- Twenty Wistar Rats Procedure...

Morphometric correlation networks of cortical thickness, surface area, and gray matter volume have statistically different structural topology. However, there is no report directly describing their correlation patterns in view of interregional covariance. Here, we examined the characteristics of the correlation patterns in three morphometric networks of cortical thickness, surface area, and gra...

watershed is regarded as a very complex system of natural, social, economic and ecological dimensions and like any similar systems, exploitation of its resources requires a comprehensive and coordinated planning and management. given the importance of watershed management projects for the development and management of natural resources, the enhancement of the efficiency of these activities is e...

this study was carried out in order to determine the leave characteristics of some chestnut genotypes in the central black sea region of turkey and also to determine whether the leaf morphometric characteristics could be used for differentiation of genotypes. in this study, seven chestnut (castanea sativa mill.) genotypes (sa5-1, se 3-12, se 21-2, se 21-9, 552-8, 556-7 and 556-8) and one cultiv...

The black-striped pipefish, Syngnathus abaster, is a species of the Syngnathidae family. This study provides data on the morphometric, meristic and genetic structuring of the Caspian Sea pipefish, Syngnathus abaster. Eight morphometric characteristics based on total length and five morphometric characteristics based on standard length were analyzed. A total of 50 specimens were collected in bra...
