On the morphological variability of Ichniotherium tracks and evolution of locomotion in the sistergroup of amniotes
Ichniotherium tracks with a relatively short pedal digit V (digit length ratio V/IV < 0.6) form the majority of yet described Late Carboniferous to Early Permian diadectomorph tracks and can be related to a certain diadectid clade with corresponding phalangeal reduction that includes Diadectes and its close relatives. Here we document the variation of digit proportions and trackway parameters i...
متن کاملEffect of morphological development on the locomotion function of Nile tilapia, Oreochromis niluticus during early ontogeny
This study was conducted to investigate the hydrodynamic parameters and how morphological changes affect them in Oreochromis niloticus at the National Museum of Natural History-Paris in the winter of 2020. To record fish movement, a high-speed camera (1000 fps) with a macro lens was used. The fish trajectory was taken by calculating coordinates of a center point between the two eyes and kinemat...
متن کاملGenetic Diversity of Genotypes of Durum Wheat (Triticum Turgidum L.) Genotypes Based on Cluster and Principal Component Analyses
Genetic diversity is the basis of the natural evolution of plant breeding and biological system are important components of sustainability. The aim of this study was to evaluate 116 genotypes of Triticum turgidum from seven countries in terms of morphological traits. The results showed that high significant differences among the genotypes. The correlation between gra...

متن کاملPhylogeny and morphological traits evolution of Astragalus sects. Acanthophace and Aegacantha in Iran on the basis of nrDNA ITS and rpl32-trnLUAG sequences
In this study, phylogenetic relationships and evolutionary trends of morphological characters of Astragalus sects. Acanthophace and Aegacantha were studied using nrDNA ITS and rpl32-trnLUAG datasets while Astragalus stocksii was selected as the outgroup. The phylogenetic results indicated the non-monophyly of A. sect. Acanthophace in its current circumscription due to the distant exclusion of A...
