FOR201H1 Lecture Notes - Lecture 4: Diurnality, Beetle, Poison Dart Frog
Document Summary
Lecture 5 tropical forest vertebrates: overview of diversity and ecology. Among them there are deep evolutionary diversity. Just discovered in south east asia in 2017: tapanuli orangutan (pongo taoanulienses ) Distinct in terms of genetics and morphology. Galagos, pottos, tarsiers: restricted to the paleotropics. Frugivorous: fruit eating, majority of primates, more active. More complicated digestive system (such as multiple stomaches). Less active, staying to digest most of the time. Folivorous monkeys can be very abundant, since there are a lot of leaves in forests. Genetics and morphology based species split imply these species do not interbreed. Mammals that are ecological engineers: they construct their own habitats. Rodents: the most speciose group of tropical mammals. Bats: the most abundant group of tropical mammal. Bats are important fruit dispersers and pollinators. They are also great for controlling insect population. Latin america: maned wolf, cougar, jaguar, spectacled bear. Se asia: leopard, clouded leopard, sun bear, sloth bear, dhole, tiger.
