Morphological study of the male genital organs of Gracilinanus microtarsus

Abstract: Gracilinanus microtarsus is one of the smallest marsupials on earth. Since it spreads seeds, it has great ecological relevance. However, its reproduction data, especially those related to the anatomy of its reproduction apparatus, are scarce in the literature. Current analysis describes the male genital organs of six adult specimens of G. microtarsus. Macroscopic studies were undertaken on dissected organs, whereas histological studies were performed by inclusion technique in paraffin and by hematoxylin and eo… Show more

“…Gracilinanus microtarsus is one of the smallest marsupials on Earth, measuring between 20 and 25 cm long, with the tail making more than a half of its length (LIMA et al, 2013). Specimens of the species have body mass average between 10 and 44 grams and exhibit nocturnal and arboreal habits (EISENBERG; REDFORD, 1999;CÁCERES et al, 2008;LOBO et al, 2014).…”

“…Members of research group have made morphological comparative studies related with digestory organs in omnivorous wild mammals as Nasua nasua (SANTOS et al, 2010;SOUZA et al, 2012), Procyon cancrivorus , Didelphis marsupialis , Callithrix jacchus, C. penicillata and C. geoffroyi (BERTASSOLI et al, 2013) in order to establish possible morphological pattern between the species.…”

“…Similarmente ao que ocorre na maioria dos marsupiais, as glândulas sexuais acessórias de Metachirus são a próstata e as glândulas bulbouretrais (Rodger & Hughes 1973, Setchell 1977, Temple-Smith 1984Tyndale-Biscoe & Renfree 1987, Dawson et al 1988, Ribeiro & Nogueira 1982, Nogueira 1989, Martinelli 1990, Costa et al 1994, Costa 1995, 1996, Barros et al 2003, Cruz et al 2011a, 2011b, Nogueira 2012, Lima et al 2013.…”

“…Em marsupiais americanos já estudados a próstata é bem desenvolvida, do tipo disseminada e possui três segmentos distintos (cranial, médio e caudal), em cor, diâmetro e extensão (Chase 1939, Ribeiro1981, Martan 1983, Garcia & Gonçalves 1984, Martinelli 1990, Costa 1995, 1996, Carvalho 1996, Barros et al 2003, Lima 2013. Devido às diferenças de segmentação da próstata entre marsupiais americanos e australianos (Rodger & Hughes 1973, Dawson et al 1988, tornou-se difícil comparar os segmentos prostá-ticos entre os dois grupos.…”
