Tropical Rainforest A.k.a Wet Equatorial / lowland equatorial evergreen rainforest / tropical moist broadleaf forest By Ryan Asensio Loryn Smith Molly Jerzy
Location • Queensland National Parks (NE Australia)
Climate • Average • Temperature: 70F • Precipitation: 103 in (262 cm) • Influences on climate: • Position of sun • Earth’s rotation (Winds) Iquitos, Peru
Plant Adaptation • Epiphytes • Attach to canopy trees to get sunlight • Absorb moisture from air • Get nutrients from dust • Kapok Tree • Tall to catch sunlight • Spines from trunk to discourage damage • Plank-like buttresses • Bromeliads • Waxy leaves • Leaves arranged in bowl • Release CO2 at night to conserve H2O
Animal Adaptation • Proboscis Monkey • Nose used to amplify “honks” • Long arms to move about trees • Complex stomach to digest leaves • Two-toed sloth • Claws to grip trees • Algae grows in grooves of hair • Complex stomach to digest leaves • Toco Toucan • Wide tail for balance • Bill disperses heat • Nest in holes in trees
SOIL AND CHEMICAL CYCLING YEAH! • Soil quality is very poor • 1-2 inches humus, beneath is clay • Organic matter is broken down and reabsorbed quickly • Water quality • Nutrients low (high demand of orgs.) • High B.O.D (concentrated # of orgs.)
Economic Value Slide • Medicinal value • 37% of prescribed in U.S. • <5% tested for medicinal value • CO2 absorption (1 ton/ha) • Oxygen production • 20% from Amazon basin • FRUITS! Yeah! • 3,000 types of fruit (estimated) • Only 200 used in U.S.
Human Disturbance • Clearing for farmland (poor soil->erosion) • Subsistence & commercial • Hydroelectric Dams • Brazil- causes flooding • Pollution • Urbanization • Hunting/Poaching • Alien Species • Tourism
EEEEK! DEFORESTATION! • http://rainforests.mongabay.com/deforestation_alpha.html

Bengal Tiger Panthera tigris tigris
Characteristics • Located: The Bengal Tiger is mostly found in India, Bangladesh, Nepal, Bhuton, and Burma.
Characteristics cont’d… • Range: They will travel several miles to find prey and will also stray from their marked territory for it. • Migrate?: No • Disperse?: Between 18 months and 2 years the Bengal Tiger cubs will leave their mother and find their own territory.
Characteristicscont’d… • Niche: The Bengal Tiger is the largest cat and a territorial predator.
Characteristics cont’d… • Eating Habits: Bengal Tigers are equipped to hunt down and kill their pray fast. Their eating habits range from termites to elephant calves but they mainly eat prey weighing in 45lbs. For example, tapirs, hog deer, takin, etc.
Characteristics cont’d • How do they live?: Bengal Tigers are nocturnal. They are also very solitary and do not like to share hunting grounds and they need large home ranges in which to hunt. • Tigers usually have several dens within their home ranges and uses whichever one is more convenient.
Characteristics cont’d… • Habitat: The Bengal Tiger primary lives in mangrove forests in India and Bangladesh. • Size/conditions needed: The Bengal Tiger’s territory is about 250 miles in size. They also need an ample food supply to properly mate and feed their young.
Causes of Endangerment • The Bengal Tiger is endangered because of man. Poachers hunt tigers for their fur and different body parts which are sold illegally in markets. • Bengal Tigers are believed to have mystical, magical powers by ancient cultures and that is another reason why poachers still hunt them today.
Level of Endangerment • Their current level of endangerment is that the Bengal Tiger is endangered. • It is at a high risk because even though there was a law passed to help protect the tigers, they are still getting killed by humans everyday. • There are about 1,800 tigers left.
Status of Bengal Tigers • India has an extensive conservation program at the Corbett National Park, where there are over 100 Bengal Tigers. • Tiger conservation programs are also in place in Ranthambore National Park, and Kanha National Park in India. Along with the World Wildlife Fund (WWF), India has set up "Project Tiger" a nationwide project to help the preservation and conservation of tigers in the wild.
Endangered Species Act -Came into effect in 1973 -The United States authorized it when President Richard Nixon signed it on December 28, 1973.
Provisions of the law: 1-authorizes the determination and listing of species as endangered and threatened 2-prohibits unauthorized taking, possession, sale, and transport of endangered species 3-provides authority to acquire land for the conservation of listed species, using land and water conservation funds 4-authorizes establishment of cooperative agreements and grants-in-aid to States that establish and maintain active and adequate programs for endangered and threatened wildlife and plants 5-authorizes the assessment of civil and criminal penalties for violating the Act or regulations 6-authorizes the payment of rewards to anyone furnishing information leading to arrest and conviction for any violation of the Act or any regulation issued there under
Enforcement of the law: Who enforces the law? - The U.S. Fish and Wildlife Service (FWS) - The National Marine Fisheries Services (NMFS) • How is the law Enforced? • - you could be arrested without warrant for any violations to this law
Changes to the law: The list of endangered species is always changing. Animals can go from being endangered to being perfectly fine, and some can go from being fine to endangered, we’ll never know what is going to happen next
How this law applies to our endangered species… The Bengal Tiger = ENDANGERED!
