Abundant habitats and niches Canopy: Emergents: highest trees ( ft tall) no branches at low levels Buttresses Umbrella-shaped canopy Middle Layer ( ft tall) Reduces light below Lower Layer ( ft tall) High humidity, lack of air movement
Buttresses: woody flanges thin bark; protective thorns and spikes Large leaves in lower layer Drip tips
Shrub layer: woody seedlings; palms < 3% light Ground layer Herbs and ferns Very humid, dark (<1% light) 1/3 ppt intercepted
lianas: woody climbers epiphytes (“air plants”) Stranglers Heterotrophic plants (non- photosynthetic) Saprophytes Parasites
lianas
Abundant and diverse decomposers
stranglers
Some strategies: Adaptation to arboreal Bright colors Loud sounds Fruit diets Diurnal patterns Highly specialized : 3 toed sloth feeds only on Cecropia tree
