Here we describe an eight-year-old miniature schnauzer (MS) dog from Brazil with Persistent Mullerian Duct Syndrome (PMDS) and the single base pair substitution in AMHR2 exon 3, first detected this breed USA. This finding is evidence of mutation dissemination to South America. In PMDS, a type XY Disorder Sex Development (DSD), dogs male karyotype external phenotype also have uterus, oviducts, cranial vagina internally. Approximately half PMDS MS are unilaterally or bilaterally cryptorchid...
Sapajus nigritus (Primates: Cebidae) is endemic of the Atlantic Forest, occurring from Southeastern and Southern regions Brazil to Northeastern Argentina. This species plays a role in two ecosystem services: seed dispersal through endozoochory insect population control agricultural plantations forest environments. Fruits invertebrates represent approximately 90% their diet, there large number insects diet S. urban conserved areas. However, it known that diversity decreases anthropized Our...
The classification of capuchin monkeys represents one the greatest taxonomical controversies within primates. high variability presented by species, observed mainly in coat coloration, makes captive animals difficult. objective present study was to analyze patterns constitutive heterochromatin 26 individuals kept a screening center wild Rio de Janeiro state, Brazil, and correlate them with phenotypic characteristics, order improve management captivity. Metaphasic chromosomes were obtained...

 Estudos sobre primatas muitas vezes requerem captura utilizando armadilhas ou dardos tranquilizantes. Entretanto, mesmo empregando a metodologia adequada, podem ocorrer injúrias devido ao estresse. Nosso objetivo foi relatar um caso de agressão durante conjunta dois macacos-prego (Sapajus nigritus) em armadilha, resultando na morte deles. Os foram capturados armadilha Tomahawk Reserva Biológica Poço das Antas, Silva Jardim, RJ, Brasil. O incidente registrado por câmera trap. Ao...
