1

Carnivora

~ order
~ carnivores e.g. cats, dogs, lions
~ distinctive skull structure
~ mostly meat eaters, some herbivores

2

Perissodactyla

~ order
~ odd-toed ungulate e.g. rhino, tapir, horse
~ herbivores w/ specialised digestion
~ hoofed mammals
~ walk on tiptoe

3

Artiodactlya

~ order
~ eye-toed ungulate e.g. hippos, deer, antelopes, cattle
~ herbivores w/ specialised digestion
~ hoofed mammals
~ walk on tiptoe

4

Monogamy

~ 1 male + 1 female
~ tends to occur in hunting species (male cares for offspring)

5

Polygamy

multiple mating

6

Polyandry

1 female + multiple males

7

Polygyny

1 male + multiple females

8

Name the 3 types of polygyny.

~ female defence polygyny
~ resource defence polygyny
~ scramble competition polygyny

9

Polygynandrous

multiple males + multiple females

10

Name the important influences for social systems.

~ diet, habitat + density
~ predation pressure
~ social foraging/hunting
~ thermoregulatory benefits
~ breeding constraints

11

Name the important influences for mating systems.

~ gestation + lactation (length for females)
~ diet, habitat + density

12

Solitary life

good option if territories/resources are easily defended

13

Semi-solitary

many mammals form temporary groups under certain conditions
e.g. reproduction, protection, warmth

14

Sociality

~ mammals live in groups al year round
~ often w/ limited cooperation
~ some social behaviours
~ individuals breed independently

15

Communal breeding

~ stable group
~ cooperation is advantageous
~ offspring care is shared

16

Cooperative breeding

~ non-breeders benefit from helping e.g. there is breeding constraints (food)
~ rare in mammals
~ restricted to carnivores, primates + rodents
~ reproductive suppression - only 1 female breeds

17

Eusociality

non-breeding females are sterile
~ breeding females (queens) + worker specialisation
~ only 2 spp.
e.g. naked mole rat

18

Mammals are...

viviparous = give birth to live young
endothermy = warm-blooded
