Dados de reprodução de Platyrrhinus lineatus em estudo de longo prazo no Estado do Rio de Janeiro (Mammalia, Chiroptera, Phyllostomidae)

Abstract

ABSTRACT. Data on reproduction of Platyrrhinus lineatus in a long-term sampling study in the state of Rio de Janeiro (Mammalia, Chiroptera, Phyllostomidae). Based on a large bat sampling we analyzed the reproductive biology of Platyrrhinus lineatus (E. Geoffroy, 1810) in the Atlantic Forest, southeastern Brazil. The bats were captured with mist nets from 1989 and 2005, in 27 of the 41 different localities sampled. The beginning of reproductive season was estimated 30 days before the date of capture of the first pregnant female. For determination of the end of the reproductive time we used the date of the capture of the last lactating female, added by 40 days. The total of 688 adult bats was analyzed, of which 58.3% were females.

Biology of Vampyressa pusilla (Wagner) in Rio de Janeiro State, southeastern Brazil (Mammalia, Chiroptera, Phyllostomidae)

“…Pedro et al (1997) found a pregnant female in October in southern São Paulo State. The capture of pregnant females in April and August suggests a large breeding season as recently described for Platyrrhinus lineatus (E. Geoffroy, 1810) (Costa et al, 2007). The breeding season of V. pusilla is similar to other frugivorous species at the same latitude (e.g.…”

“…The breeding season of V. pusilla is similar to other frugivorous species at the same latitude (e.g. Taddei, 1976;Mello and Fernandez, 2000;Costa et al, 2007), with maximum peak of capture of reproductive females in the rainy months and a smaller one in the early dry season (see Mello and Fernandez, 2000).…”

Reproductive biology of Artibeus fimbriatus Gray 1838 (Chiroptera) at the southern limit of its geographic range

“…Other species of the Artibeus genus, including A. lituratus and A. jamaicensis Leach, 1821, also show seasonal reproduction, with the highest rates of pregnancy observed during the warmest seasons in Panama (Fleming et al 1972;Bonaccorso 1978), Venezuela (Sosa & Ramoni-Perazzi 1995) and in different localities of Brazil (Taddei 1976;Willig 1985;Reis 1989). This pattern has also been observed for other species of the Phyllostomidae family, such as Uroderma bilobatum Peters, 1866, Carollia perspicillata Linnaes 1758 (Fleming et al 1972), Sturnira lilium (E. Geoffroy, 1810) and Platyrrhinus lineatus E. Geoffroy, 1819 (Estrada & Coates-Estrada 2001;Stoner 2001;Costa et al 2007). …”

“…In Costa Rica, A. jamaicensis was reported to have a 9-month reproduction period. In southeast Brazil, Sturnira lilium was reported to have an 11-month reproduction period (Godoy et al 2014) and Platyrrhinus lineatus presented a 10-month reproduction period (Costa et al 2007). …”

Reproductive biology of the bat Sturnira lilium (Chiroptera, Phyllostomidae) in the Atlantic Forest of Rio de Janeiro, southeastern Brazil

“…For each individual we recorded the following parameters: age, distinguishing juveniles from adults through epiphysis ossification (Anthony, 1988); fur color; sex; and reproductive condition -males were classified as having scrotal or abdominal testes, and females were classified as sexually inactive, with palpable fetus or lactant (Zortéa, 2003;Esbérard, 2012). We classified the females that were simultaneously pregnant and post-lactating, with hairless swollen nipples, without milk secretion, and without a palpable fetus as being in the second reproductive cycle (Costa et al, 2007). Up to 1997, the animals were marked with a tattoo plier and from 1998 on with plastic necklaces with colored cylinders (Esbérard and Daemon, 1999).…”
