koala brain to body ratio

[172], One of the biggest anthropogenic threats to the koala is habitat destruction and fragmentation. Brain-to-body mass ratio, also known as the brain-to-body weight ratio, is the ratio of brain mass to body mass, which is hypothesized to be a rough estimate of the intelligence of an animal, although fairly inaccurate in many cases.A more complex measurement, encephalization quotient, takes into account allometric effects of widely divergent body sizes across several taxa. They are too thick to adapt their feeding behaviour to cope with change. The small brain is posited to be an adaptation that balances the energy restrictions imposed from its strict diet, and thus the animal cannot carry out complex behaviours and lives quite simply (4). [168], Since 1870, koalas have been introduced to several coastal and offshore islands, including Kangaroo Island and French Island. The small brain is posited to be an adaptation that balances the energy restrictions imposed from its strict diet, and thus the animal cannot carry out complex behaviours and lives quite simply (4).
