“…Bats from Guam's only remaining colony are suspected to forage up to 10-12 km from their roosting site. Wiles and Glass (1990) provide evidence of inter-island movements. On rare occasions, groups of 50-300 bats fly 60-80 km between Rota and the neighbouring islands of Guam and Aguijan.…”

“…In total, there were 240 bats in early April and 508 bats in mid-May. The sudden increase was probably due to immigration from Rota (Wiles and Glass, 1990). In 1981-82, the colony increased from an estimated 600 at the end of 1981 to 780-850 in 1982.…”

“…Populations of P. mariannus on a number of the Mariana Islands have never been identified to subspecies level. Recently, Wiles and Glass (1990) questioned the validity of distinguishing two subspeciesof P. mariannus in the Mariana Islands. This was based on the evidence of movements of P. mariannus between islands, which would facilitate gene flow through the chain.…”

“…(Wiles et al, 1989) indicated that there were fewer than 10 bats on Aguijan. However, approximately 300 bats were seen in 1988 (Wiles and Glass, 1990). The population declined to about 50 bats in 1989 (Stinson et al, 1992).…”

Nipah virus, member of the Paramyxoviridae family, is classified as a Biosafety Level-4 agent and category C priority pathogen. Nipah virus disease is endemic in south Asia and outbreaks have been reported in Malaysia, Singapore, India, and Bangladesh. Bats of the genus Pteropus appear to be the natural reservoir of this virus. The aim of this study was to investigate the genetic diversity of Nipah virus, to estimate the date of origin and the spread of the infection. The mean value of Nipah virus N gene evolutionary rate, was 6.5 × 10(-4) substitution/site/year (95% HPD: 2.3 × 10(-4)-1.18 × 10(-3)). The time-scaled phylogenetic analysis showed that the root of the tree originated in 1947 (95% HPD: 1888-1988) as the virus entered in south eastern Asiatic regions. The segregation of sequences in two main clades (I and II) indicating that Nipah virus had two different introductions: one in 1995 (95% HPD: 1985-2002) which correspond to clade I, and the other in 1985 (95% HPD: 1971-1996) which correspond to clade II. The phylogeographic reconstruction indicated that the epidemic followed two different routes spreading to the other locations. The trade of infected pigs may have played a role in the spread of the virus. Bats of the Pteropus genus, that are able to travel to long distances, may have contributed to the spread of the infection. Negatively selected sites, statistically supported, could reflect the stability of the viral N protein.

Geographical distribution pattern and interisland movements of Orii's flying fox in Okinawa Islands, the Ryukyu Archipelago, Japan

The study of mobile animals such as flying foxes in insular habitats involves clarifying the population status on each island and determining the factors affecting movement patterns among the islands in their distributional range. We visited 25 of the Okinawa Islands and documented the number of Orii's flying foxes Pteropus dasymallus inopinatus from August 2005 to May 2006. We also conducted a monthly road census on the main island (Okinawa-jima Island) and six adjacent islands from June 2006 to January 2007 and counted the number of fruit-bearing trees of the bats' four main food plants. The results of classification and regression tree analysis suggested that distance from the main island was a primary factor in determining the distribution pattern and population size of this flying fox, whereas island area, number of plant species, and food availability did not directly affect population size. The number of flying foxes on each island tended to decrease with an increase in distance from the main island; no flying foxes existed on islands [30 km away from the main island. On the other hand, the results of the monthly census showed that the population size on each island fluctuated seasonally. Individuals may move between islands in response to seasonal changes in food availability. In conclusion, the distribution and abundance of Orii's flying foxes in the Okinawa Islands may be determined by the rate of immigration/emigration, depending on each island's distance from the main island. Seasonal changes in food availability may act as a trigger for interisland movement, but that movement may be restricted by island connectivity.
