Sexual Size Dimorphism in Rays and Skates (Elasmobranchii: Batoidea). [PDF]
Ecol EvolInterspecific trends in sexual size dimorphism are superficially similar in batoids to sharks, but are underlain by different modes of evolution. Selection for substantial SSD in batoids seems to be weaker than in sharks. This may be due to differences in the strength of fecundity selection.

Molecular and morphological analyses reveal phylogenetic relationships of stingrays focusing on the family Dasyatidae (Myliobatiformes). [PDF]
PLoS ONE, 2015 Elucidating the phylogenetic relationships of the current but problematic Dasyatidae (Order Myliobatiformes) was the first priority of the current study. Here, we studied three molecular gene markers of 43 species (COI gene), 33 species (ND2 gene) and 34

Species boundaries in the Himantura uarnak species complex (Myliobatiformes: Dasyatidae) [PDF]
Molecular Phylogenetics and Evolution, 2013 Samples of the 'Himantura uarnak' species complex (H. leoparda, H. uarnak, H. undulata under their current definitions), mostly from the Coral Triangle, were analyzed using nuclear markers and mitochondrial DNA sequences. Genotypes at five intron loci showed four reproductively isolated clusters of individuals.
