1. Researchers studying snow monkeys in Japan found that they rely on aquatic insects for nutrition during winter, especially when food is scarce.
2. The number of aquatic insect species decreased significantly in February last year due to higher temperatures causing upstream snowmelts and rising river levels, making it difficult for the monkeys to access their food source.
3. Assistant Professor Masaki at the University of Tsukuba suggests that increased and localized temperature rises caused by climate change may alter the environment and affect the feeding habits of winter snow monkeys, indicating potential impacts on their behavior.
