The Neotropical freshwater stingray Potamotrygom orbignyi (Castelnau, 1855), and other similar "reticulated" species occurring in northern South American basins, were submitted to a thorough taxonomic analysis based on an extensive external and internal morphological study. The identity of P. orbignyi and the taxonomic status of the related nominal species Potamotrygon dumerilii (Castelnau, 185...

Grain yield has a usually the low heritability, consequently to predict this trait it is recommended to use some morphological characters having a high heritability with high correlation with grain yield. To study of relationships between traits and to find out traits having the high influence on grain weight, 36 winter wheat cultivars were planted through a randomized complete block design wit...

Morphology has been the subject of several studies in Eunice specially in the context of the taxonomy and evolutionary relationships of taxa within this genus. In this study we opt for a morphometric approach comparing five species of Eunice to assess if it was possible to delimitate them by shape variables. The morphology of E. fucata, E. insularis, E. cf. ornata, E. rubra, and Eunice sp. was ...

A new species of pit crab of the genus Fizesereneia Takeda & Tamura, 1980, Fizesereneia daidai sp. nov., is described and illustrated based on specimens collected from the scleractinian corals Micromussa amakusensis and Micromussa sp. in Japan. The new species, the sixth assigned to the genus, can be separated from its congeners by having an orange posterior carapace in life, a subrectangular c...
