What is Adaptation? “...the way in which a species becomes better suited to living in its environment.” 2
Movement • There are many different methods of movement • Different habitats present different problems to movement that need to be overcome • Specialists vs. Generalists Leopard seal – aquatic specialist 3 Good in water... ...cumbersome on land
Why move? Common warthog fleeing from cheetah American pika collecting food 4 Grass snake hatchlings dispersing Radiated tortoises mating
Bornean orangutan Snow leopard Rainforest River Desert Which habitat? Polar Ocean Woodland Mountains Open grassland Red squirrel Nile crocodile 5
Bornean orangutan Snow leopard How are they adapted to move in their habitat? Red squirrel Nile crocodile 6
Adaptations to moving on land Movement on Land • Things to think about: • Speed vs. agility • Move to catch prey or to escape predators • Land may be open or have obstacles such as trees • Moving over different substrates e.g. sand, snow, mud 7
Cheetah • Open plains specialist • Adapted for speed
Spanish ibex • Rocky habitat specialist • Adapted for agility 9
Polar bear • Habitat generalist – can move over land and in water • Adapted to polar habitat 10
Legless movement • Movement without limbs • Adapted to overcome friction 11 Sidewinder Leopard slug
Adaptations to arboreal movement Arboreal Movement • Things to think about: • Forested areas may not be continuous • Moving from one tree to another • Balance and grip
Fossa • Habitat generalist – can move quickly through trees as well as • on the ground • Adapted to jump between branches 13
White-handed gibbon • Master of agility • Adapted to swing between branches 14
Sugar glider • Arboreal specialist • Adapted to glide between trees 15
Adaptations to aquatic movement Aquatic Movement • Things to think about: • Friction – causing drag • Buoyancy – saline vs. freshwater • Currents and tides 16
Great white shark • Aquatic specialist • Adapted for speed 17
Spotted handfish • Aquatic specialist • Two different methods of moving through water 18
Adaptations to aerial movement Aerial Movement • Things to think about: • Overcoming friction • Use of air currents • Hot air vs. cold air 19
Peregrine falcon • Common swift • Aerodynamic body shape • Adapted for speed 20
California condor • Aerial movement using thermals • Adapted for gliding 21
Wild Journey • - You will be given an ‘Adaptations for Movement’ worksheet. • - Write in the adaptations that each species has for moving through its natural habitat. • Once you have finished the worksheet, you can begin your ‘Wild Journey’ • Get into groups of 5 or less • Each group will need: • 1x Wild Journey board game • 5x Species characters - use as your playing pieces on the board • 5x Species fact files - explains how your particular species is • adapted to moving through its natural habitat • 1x Rules sheet - read before beginning the game
If you land on your natural habitat square: roll the dice again. • If you land on your least suitable habitat square: miss a go!
