“…In 2005, the privately owned Montfort Bat Cave Sanctuary on Mindanao Island, south of the Philippines, opened for tourism. The five-chambered cave hosts the world's largest known colony of the Geoffroy's Rousette Fruit Bat, Rousettus amplexicaudatus, with an estimated 1.8-2 million individuals [76].

Bats - Disease-Prone but Beneficial

Belief systems of people have always been closely related to animals, which are symbolized in traditional narratives. Sociocultural definitions of animals as “good or evil” have persisted throughout the history of human beings. In the West, bats are often perceived as evil spirits, Vampires, and harbingers of death, while some cultures across the Asia-Pacific region associate bats with good fortune. Here, we review documented narratives and surveys from around the world and our ethnographic observations from Europe to analyze beliefs associated with bats. We explore the role that bats play in traditional narratives and the likely reasons for their salience, including their connections with the extraordinary and supernatural. Finally, we discuss shortly the need of education to change attitudes toward bats. In North America, education has had some effect as more people have started to understand how useful bats truly are and how few cases of bat-born rabies transmission to humans there have been in the United States and Canada . It remains to be seen, however, how effectively the further education efforts could halt or even reverse the decline of the bats around the world. It is also noted that bat tourism has a potential to conserve bat populations while providing social and economic benefits to local people in host communities.

“…We conducted a field observation on the Island of Samal located within the Gulf of Davao in the southern part of the Philippine Archipelago at the world's largest colony of the Geoffroy's Rousette (Rousettus amplexicaudatus, Chiroptera: Pteropodidae) (estimated population at present 2 million) (Carpenter at al. 2014) (Figure 1A) in the Monfort Bat Cave (7 o 09'53"N, 125 o 41'31"E).…”

“…Monfort Bat Cave is a relatively small cave with an approximate size of 150-metre length with an average 3 metres high and 5 metres wide. The cave system can be accessed through its horizontal entrance (opening #1) and four vertical openings (Carpenter at al. 2014).…”

Predation of bats in their roosts has previously only been attributed to a limited number of species such as various raptors, owls, and snakes. However, in situations where due to overcrowding and limited roost space, some individuals may be forced to roost in suboptimal conditions, such as around the entrances of caves and may thus be vulnerable to predation by species which would normally be unlikely to predate bats whilst roosting inside caves.

“…This was done by three people individually and averages were calculated. Besides that, photographs (camera model DSC-HX1, Sony, Tokyo, Japan) were taken in each cave representing different roosting densities and bats on the photographs were counted (Carpenter et al 2014). The average of visual and photographic counts was used for analysis.…”

Explaining diversity patterns in dark waters – a study of aquatic caves in Yucatán, Mexico

et al. 2019

In the tropics, limestone caves in karstic areas are known for their unique biodiversity. However, many caves remain unstudied and little is known about underlying gradients that determine diversity and biomass in aquatic microhabitats. Here, we sampled zooplankton and benthos in a set of 12 aquatic caves, locally called closed cenotes in Yucatán, Mexico. Our aim was to explain diversity patterns and differences in biomass with particular attention for correlations between bat colony characteristics and other biota. Compared with caves that support photosynthesis, diversity was low with an average of four planktonic and two benthic species in these dark caves. Undetectable phosphorus concentrations in the water suggest this nutrient is limiting. Several associations hint at a potential link between bat abundance and functional guild composition, water quality and aquatic biota. As such, more bats were linked to higher nitrate concentrations. Yet this was not translated to higher invertebrate biomass, probably since phosphorus is limiting. Overall, the trends found in this survey suggest that bats could be important as fertilizers of the caves although mechanistic links that mediate the flux of nutrients need to be confirmed experimentally.
