1. Adaptations
= An inherited trait that increases an organism’s ability to survive and reproduce

2. Can be: Structural - Behavioral
a physical trait that aids an organism in competing for resources (eg. stronger or faster) or evading predators
Behavioral
a behavior that increases an organisms ability to survive or find a mate

3. STRUCTURAL ADAPTATION EXAMPLES
Plants that use pollinators often use the ‘bullseye’ pattern to attract bees, butterflies, etc.
This pattern has
evolved many times
Example: black-
eyed Susan

4. CACTUS PLANTS
Cactus plants in the desert have leaves specially designed to:
Store water
Tolerate long periods of dehydration without harm to tissues

5. Desert Animals Structural Modifications to dissipate heat
long appendages (legs, ears, etc.), or small "bodies" (e.g., whole body, leaves, etc.) that radiate heat.

6. California Kingsnake
Adaptations to consume its favorite food – Rattlesnakes!
Hinged jaw – consume food larger than its own head
Tolerance to rattlesnake venom

7. Dendrobates – or poison dart frogs
Some species have skin that is extremely poisonous – even to the touch
Bright markings warn predators they are poisonous

8. Lady Slippers Orchids Petal has evolved into pouch
Aroma of orchids makes flies act intoxicated
Have so much fun – move to second pouch = pollination!

9. BEHAVIORAL ADAPTATIONS
EXAMPLES

10. Blue-footed Boobies Blue feet used in their elaborate mating ritual
Male struts around female, raising one foot at time, whistling, bringing sticks as ‘gifts’

11. Prairie Dogs Example of a social animal
Build huge tunnel ‘town’ to evade heat & escape predators
Adaptation to make a range of vocalizations
Bark = warning
Rasp = impending attack
Scream = pain
