Melanocytes in the testes of Eupemphix nattereri (Anura, Leiuperidae): Histological, stereological, and ultrastructural aspects
(Wiley-Blackwell, 2007-07-01)
Ectothermic vertebrates have a well-developed system of melanin-containing cells, which localize in several organs and tissues and compose an extracutaneous pigmentary system. This research aimed at characterizing histological ...
Spermiogenesis and sperm ultrastructure as sources of phylogenetic characters. The example of characid fishes (Teleostei: Characiformes)
(2020-11-01)
Fish sperm morphology is quite diverse. In the last decades our and other studies on Teleostei, mainly on Ostariophysi with emphasis in the Characiformes, have showing that the features of these spermatozoa can be used in ...
