Rivulus berovidesi, a new killifish species, is described from a small stream in Sierra de Cajalbana, northwestern Cuba. It is readily distinguished from Rivulus cylindraceus Poey by the combination of an exclusive color pattern and meristic characters such as a d-type frontal scalation pattern (versus e-type pattern in Rivulus cylindraceus). The current diagnosis of Rivulus berovidesi based on...

Genus Scardinius (Cypriniformes, Actinopteri) belongs to the family Leuciscidae, subfamily Leuciscinae, and it includes 10 species. Phylogenetic morphometric research conducted so far have shown a great taxonomic complexity within this genus. Therefore, aim of was determine morphological diversity contribute clarification relationships status S. dergle plotizza. For purpose specimens plotizza w...

Morphological characteristics such as meristic counts and body shape have long been used in stock identification. Fifty striped seabream, Lithognathus mormyrus, individuals were sampled from the south Black Sea between January 2020 November 2020. Morphometric characteristics given percentage of total length (TL%). Species identification differences sexes seabream analyzed by different statisti...

landmark based geometric morphometrics and comparison of meristic characters was used to understand potential differences between populations of waspi in mashkil and mokran basins. 97 specimens of waspies were caught (64 from mashkil river and 33 from sarbaz river). 14 landmarks were digitized on pictures taken from left side of specimens and meristic characters were counted. data were analyzed...
