Adaptations : The Prickly Pear Cactus • Conserves water by not having leaves • Fleshy stems store water and swell during rain. • Has spikes to deter grazers • Toxic calcium oxalate under the skin. Only woodrats and javalinas can metabolise this chemical without harm to kidneys.. Engelmann’s Prickly Pear
Adaptations : Creosote Bush • Contains toxic chemicals makes most animals ill if they eat the leaves. • Resins on the leaves reduces water loss by evaporation • Bright yellow flowers attract large variety of pollinating insects.
Adaptations : Organ Pipe Cactus • Large number of branches increase the surface area: to maximise food production • Grows near rocks and cliff edges to receive their heat radiation at night. • Flowers only bloom at night: they use bats to pollinate the blossoms.
Adaptations : Mesquite Tree • Mature trees can produce up to 11kg of fruit , containing over 140,000 seeds ! • The flowers attract many different pollinators, including sixty species of bees. • Many birds, insects and mammals eat the beans
Adaptations : Hummingbird • Its food is nectar from flowers, tiny insects, and sugar water. • Hummingbirds burn food so fast they often eat 1.5 to 3 times their body weight in food per day • To conserve energy, it can go into a sleep-like state known as "torpor."
Adaptations : Hummingbird • Hummingbirds migrate in response to hormonal changes that are triggered by the changing length of a day. • They prepare for migration by putting on a lot of fat. They may double their body weight.
Adaptations : Gila Woodpecker • Sharp and strong beak to get at insects and to make out nest holes • Beak is also used to to hammer out its ‘territory’ signals. • Strong claws and short legs enable it to climb trees • Lives in nest cavities of trees.
Adaptations : Cardinal • Male cardinals vigorously defend their territory. They have even been known to attack their own reflections in mirrors and windows! • Females dull colours help to camouflage them from predators • Males bright colours help to attract a mate. Female Cardinal
Adaptations : The Saguaro Cactus • Can absorb up to 95% of its total weight in water when it rains. • Pleats between the ribs allow the stem to swell when water is absorbed. • Shallow root system covers a large area for maximum absorption of water. • Can live up to over 175 years
Adaptations : Agave (Century Plant) • A waxy coating with a powdery surface seals the leaf against evaporation and also reflects up to 75% of the incoming heat • Absorbs carbon dioxide at night, to be stored for photosynthesis during the day. • Flowers smell like rotting meat : this attracts bats (pollinators) Blooms only once then dies Its life is between 5-25 years
