Abstract Evidence suggests that hurricanes can influence the evolution of organisms, with phenotypic traits involved in adhesion, such as toepads arboreal lizards, being particularly susceptible to natural selection during strong storms. To investigate this idea, we quantified trait variation before and after Hurricanes Irma Maria (2017) forest urban populations Puerto Rican lizard Anolis crist...

the brush-tailed mice of the genus calomyscus are distributed in the mountains of central asia and the middle east. the genus calomyscus represents five nominate species from iran (c. bailwardi, c. grandis, c. hotsoni, c. urartensis and c. elburzensis). in total 64 specimens from four species of calomyscus were studied for morphometric analyses the morphological differences among 10 populations...

In this study, it was aimed to examine the relationship between morphometric-geometric features of meatus acusticus externus, bulla tympanica and tuba auditiva cranium shape, age, gender race characteristics in os temporale region terms clinical-anatomical approach outer ear middle regions dogs’ skull. a total 110 dog's were studied. The bones photographed three different views with camera. mor...

Morphometric analysis of biogenic recording structures within marine organisms has applications in stock assessment, taxonomics, and ecomorphological studies, with shape variation markedly influenced by both genetics the surrounding environment. Geometric morphometrics (GM) is an alternative approach to “traditional” method collecting linear measurements applying multivariate statistical method...

Modularity has been suggested to be connected to evolvability because a higher degree of independence among parts allows them to evolve as separate units. Recently, the Escoufier RV coefficient has been proposed as a measure of the degree of integration between modules in multivariate morphometric datasets. However, it has been shown, using randomly simulated datasets, that the value of the RV ...

Quantifying integration and modularity of evolutionary changes in morphometric traits is crucial for understanding how organismal shapes evolve. For this purpose, comparative studies are necessary, which need to take into account the phylogenetic structure of interspecific data. This study applies several of the standard tools of geometric morphometrics, which mostly have been used in intraspec...

Using classic morphometric techniques to examine the head and thorax of Triatoma specimens, researchers identified a possible taxonomic problem involving T. arthurneivai (Lent & Martins) and T. wygodzinskyi (Lent). A recent geometric morphometric study indicated that the insects captured outside the Serra do Cipó region, State of Minas Gerais, Brazil, were T. wygodzinskyi. The misidentification...

Several studies investigating macroevolutionary skull shape variation in fossil reptiles were published recently, often using skull reconstructions taken from the scientific literature. However, this approach could be potentially problematic, because skull reconstructions might differ notably due to incompleteness and/or deformation of the material. Furthermore, the influence of intraspecific v...
