“…Moreover, conservation strategies are currently urgent, as anthropogenic threats have already caused large reductions of certain populations, driving species toward local or global extinctions [5,6]. Despite those dramatic threats, bat semen preservation for assisted reproduction has seldom been addressed as an appropriate method for species and genetic conservation [7][8][9]. Such an approach would, however, appear most applicable in species breeding poorly in captivity and for which ex situ conservation is not a reasonable option.…”

“…However, methods have already been developed for other mammals of similar size and for flying-fox species [15,7]. After the collection, adequate ejaculate processing should provide suitable samples for subsequent analyses or utilization.…”

“…A roost on the outskirts of Boonah, 80 km south-west of Brisbane, was of particular interest because of its proximity to multiple case properties, and because the variable roost size and species composition suggested a dynamic population. In August and September 2011, we used mist-nets (18 m wide and 4 m deep) hoist between two 12 m aluminium masts to capture black flying-foxes at dusk or dawn as they, respectively, left or returned to the roost (de Jong et al 2005;Epstein and Field 2011). Our focus on black flying-foxes reflected increasing evidence that this species is an epidemiologically important in HeV transmission (Smith et al 2014;Goldspink et al 2015).…”

Landscape Utilisation, Animal Behaviour and Hendra Virus Risk

Hendra virus causes sporadic fatal disease in horses and humans in eastern Australia. Pteropid bats (flying-foxes) are the natural host of the virus. The mode of flying-fox to horse transmission remains unclear, but oro-nasal contact with flying-fox urine, faeces or saliva is the most plausible. We used GPS data logger technology to explore the landscape utilisation of black flying-foxes and horses to gain new insight into equine exposure risk. Flying-fox foraging was repetitious, with individuals returning night after night to the same location. There was a preference for fragmented arboreal landscape and non-native plant species, resulting in increased flying-fox activity around rural infrastructure. Our preliminary equine data logger study identified significant variation between diurnal and nocturnal grazing behaviour that, combined with the observed flying-fox foraging behaviour, could contribute to Hendra virus exposure risk. While we found no significant risk-exposing difference in individual horse movement behaviour in this study, the prospect warrants further investigation, as does the broader role of animal behaviour and landscape utilisation on the transmission dynamics of Hendra virus.

“…The lactation period may extend from seven weeks to four months. In seasonally breeding bats, reproductive season is demonstrated by changes in the morphology of reproduc tive tracts (de Jong et al, 2005;Miguel et al, 2005). A recent study on Rousettus leschenaultii (fulvous fruit bat) showed that this species has a human like menstrual cycle which lasted for 33 days (Xiaoping et al, 2007).…”

Seasonal variation in the reproductive tract of the Indian flying fox, Pteropus giganteus (Brünnich, 1782)

Seasonal variation in the reproductive tract of Pteropus giganteus was studied at 13 sites of the Pothwar Plateau and Islamabad Capital Territory. Ninety-three dead specimens were collected from roosts, orchards and home-based small cultivations of fruit trees. In males, seasonal differences in testis length, testis width, cauda epididymidis length and penis length were recorded. Positive correlations were found between body weight, body length and all parameters of male reproductive tract. Sig nificant monthly variations in testes conditions (viz. flaccid and turgid) were observed. In females, seasonal variation in reproductive tract weight, ovary length, ovary width, uterus length and uterus width were seen. In females, a strong relationship of body weight with total body length and female reproductive tract parameters were found. In flying foxes' population of Pothwar, first mating was observed in December-January and second in June-July, suggesting two mating seasons in winter and summer.
