Despite clinical importance and frequent occurrence of sinus disease, little is known about the size of paranasal sinuses and their communication in ponies and small horses. To examine the shape and volume of the paranasal sinuses and evaluate the sinonasal communication, three-dimensional (3D) reconstructions of computed tomography (CT) datasets of 12 healthy adult Shetland ponies were performed and analysed.

Anurans are the most suitable vertebrate group to see the development and also evolution in the skull, compared to other terrestrial vertebrates as they show highly derived morphology. For this reason, the cranium of anurans has been widely used for analyzing e.g., development and integration, evolutionary history, phylogenetic relationships, sexual dimorphism; and for taxon determination. We applied geometric morphometric techniques and then multivariate statistical analyses to see the skull size and shape variations in closely related Bufo species (B. bufo and B.

The health status of Pelophylax ridibundus species living in anthropogenic pollution sources in Erzurum (Turkey) were investigated. Firstly, heavy metal concentrations in liver of the frog species, and in water and sediment samples taken from the habitats of the frogs were determined by instrumental analysis. Secondly, morphometric (fluctuating asymmetry-FA, hepatosomatic indexHSI) and erythrometric analyses were performed to reveal the health status of the frogs in the areas. Our study provides the first morphometric datas on the frog in Turkey.

Micromorphological characteristics of 13 Trifolium species, which are grown in the province of Bolu, were examined using a scanning electron microscope (SEM). The morphological characteristics determined from the study were subjected to morphometric analyses and their variation spectrums were defined. Tricolporate pollen grains showed two pollen shapes, prolate and subprolate, according to equatorial view. The smallest size of polar axis length (18.00 μm) was found in T. micranthum Viv. from section Chronosemium Ser.; the largest (88.95 μm) was found in T. hirtum All.

Recent morphological analyses of vertebrae in patients with scoliosis have revealed three-dimensional (3D) deformities in the vertebral bodies. However, it remains controversial whether these deformities are secondary changes caused by asymmetrical vertebral loading or primary changes caused by aberrant asymmetrical vertebral growth.

A detailed evaluation focusing on the fibrocartilage layers in the anterior cruciate ligament (ACL) insertion is necessary to consider regeneration of the insertion. This study examined the development of the fibrocartilage layers in the ACL tibial insertion in rabbits by quantitative morphometric evaluations based on histological and immunohistochemical analyses.

An image analysis technique is well suited for the collection of data concerning the shape and size of the seeds. Such morphological data is often used for establishing the distinctness of new varieties. Seed morphometric characters like seed length, breadth, length to breadth ratio (seed shape) and thousand seed weight were determined for hundred rice genotypes by using Biovis image analyser.
