Just as humans may go out five minutes early to avoid a talking neighbor, or leave work late to avoid a rude colleague, carnivorous mammals may also deliberately avoid other species
Researchers installed 73 infrared trigger sensor cameras at three locations in Sabah, Malaysia, the third largest island in the world, and monitored this time niche division intermittently for more than 6 years
Miyabi Nakabayashi, assistant professor and lead author of the Graduate School of Advanced Science and Engineering at Hiroshima University, said: “About 20% of the world’s mammals are at risk of extinction, mainly due to threats such as habitat loss and overexploitation
Nakabayashi said that one of the main obstacles in effectively and realistically solving the problem of reducing the rate of endangered species is the lack of basic ecological information about mammals in Indochina
Nakabayashi said: "Information about the temporal activity patterns of animals is essential to assess the response to human disturbance and implement appropriate protective measures
The researchers collected 37,379 photos during approximately three years of active time
In the data set, the researchers identified 9 different carnivores with a sample size of more than 10, and classified their activity patterns according to the time of day
Some animals that are more closely related show significant temporal separation, including two wild cats, one of them likes to be active at night and the other likes to be active during the day
Researchers also found that tourism may have an impact on mammalian behavior
Nakabayashi said: "The potential benefits of ecotourism may include reducing threats to wildlife
The researchers also recommend a two to three-year study, using at least 10 cameras, to collect more data on the activities of predators
Nakabayashi said: "The current information is too limited and fragmented to understand the basic behavior of mammals, which may affect the progress of assessing and improving the endangered status
