anth 1001 - test 2 - 8, Tarsiers and Strepsirrhines

Generally, what are the body sizes of Tarsiers?

small bodied primate species (e.g. tarsiers, lemurs, and lorises)

Where are Lorsies found?

Africa and southeast Asia

What is the diet of Lemurs and Lorises?

insectivory

What is the mating system of Tarsiers?

noyau (or monogamy)

*Tarsiers*: Southeast Asia vertical clinging and leaping 1. very large eyes 2. LEGS LONGER than arms 3. non-prehensile tail (cant grasp) 4. dry, hairy area around the nose nocturnal (large eyes associated with this) *noyau*

...

What are 2 main points of /Lemur catta/?

1. diurnal 2. multiple-male polygyny

What are the morphologies of Tarsiers? (4)

1. very large eyes (nocturnal) 2. LEGS LONGER THAN ARMS 3. non-prehensile tail 4. dry, hairy area around the nose

Where are Lemurs found?

Madagascar - Only lemurs are found in Madagascar; no other living non-human primate is on this island

Where do large bodied primates get protein from?

leaves (folivorous)

What are the only living non-human primates on the island of Madagascar?

lemurs

What is the mating system of Lemurs and Lorises?

- noyau (ie. dispersed, one-male polygeny) - most species are nocturnal - SOME species of lemurs are diurnal, perhaps because of absence of competetion with monkeys and apes (among non-human primates, only lemurs of Madagascar)

What species do suborder Strepsirrhini consist of?

Lemurs, Lorises, /Daubentonia/, /Lemur catta/

When are Tarsiers active?

Nocturnal (active at night) (large eyes are associated with nocturnality)

What do small bodied primates do to cross gaps in forest canopies? What do SOME lorsies do to cross gaps in forest canopies?

Small bodied primates (eg. lemurs, lorises, and tarsiers) are LEAPERS to cross gaps in forest canopy SOME lorises have elongated thoracic and lumbar regions; use their body as a bridge to cross gaps in forest

Where are tasiers found?

Southeast Asia

What is the locomotion of Lemurs and Lorises?

either (vertical clinging) and leaping, or running and leaping slow, cautious climbing - Small bodied primates (e.g., lemurs, lorises, and tarsiers) are leapers to cross gaps in forest canopy - Some lorises have elongated thoracic and lumbar region; use their body as a bridge to cross gaps in forest

Where do small bodied primates (Tarsiers, lemurs and lorises) get protein from?

insects (insectivorous)

What is the Locomotion of Tarsiers?

vertical clinging and leaping

What are the morphologies of Lemurs and Lorises?

1. large eyes (nocturnal) 2. legs longer than arms 3. non-prehensile tail (cant grasp) 4. moist, hairless area around nose 5. relatively smaller brain size than tarsiers and anthropoids 6. dental formula: 2, 1, 3, 3 / 2, 1, 3, 3 7. dental comb (ie. tooth comb) - only in lemurs and lorises - lower incisors and canines are bunched together - dental comb may be used for grooming and for food procurement

What are 3 main points of /Daubentonia madagascarensis/ (aye-aye?)?

1. largest insectivore 2. unique dental formula: 1,0,1,3/1,0,0,3 3. unique hand anatomy
