Athlete’s foot is a skin disease, usually starting between the toes or on the bottom of the feet, which can spread to other parts of the body. It is caused by a fungus that commonly attacks the feet, because the wearing of shoes and hosiery fosters fungus growth. The signs of athlete’s foot are dry scaly skin, itching, inflammation, and blister

Station 2

Termites are nature's recyclers, breakingdown and returning to the soil the cellulose containing materials of fallen trees anddecaying wood. Termites derive nutrition fromwood and other cellulose materials.They cannot digest the cellulose themselves.Instead they are dependent on one-celledprotozoa in their stomachs that break downthe cellulose into simpler compounds that thetermites can use as food

STATION 3Once considered a parasite of southern climates,the heartworm (Dirofilaria immitis) is now recognizedas a major, global pest affecting dogs, wolves,coyotes, and foxes. A mosquito serves as theintermediate host for the larval stage of the worm.Adult heartworms can reach 12 inches in length andcan remain in the dog’s heart for several years.Female heartworms bear live young – thousands ofthem in a day. The worms grow and multiply,infesting the chambers on the right side of the heartand the arteries in the lungs. They can also lodge inthe veins of the liver and the veins entering theheart.

STATION 4

Epiphytes, or air plants, grow everywhere but canbe found mainly on the branches, trunks, and eventhe leaves of trees. The name 'epiphyte' comesfrom the Greek word 'epi' meaning 'upon' and'phyton' meaning 'plant'. Epiphytes grow on sidesof tall trees in an attempt to be closer to thesunlight. They have no roots, and collect waterand nutrients from the air. They begin their life inthe canopy from seeds or spores transported thereby birds or winds.

Cerambycid beetle

STATION 5

Pseudoscorpions are small, predaceous arthropods, mostly lessthan 1 centimeter is length. These scorpion like animals havepincers (chelicera) like scorpions, but lack a sting.Pseudoscorpions are common, but usually overlooked becauseof their small size and because they are concealed in the soil orunder the bark of trees.

A few species of pseudoscorpions disperse by concealingthemselves under the wing covers (elyatra) of large beetles suchas the cerambycid beetle. The pseudoscorpions gain theadvantage of being dispersed over wide areas whilesimultaneously being protected from predators. The beetle is,presumably, unaffected by the presence of the hitchhikers.

STATION 6

In many bee-pollinated flowers, there is aregion of low ultraviolet reflectance near thecenter of each petal. This pattern is invisibleto humans because our visual spectrum doesnot extend into the ultraviolet. Bees, however,can detect ultraviolet light. The contrastingultraviolet pattern (called a nectar guide) helpsa bee quickly locate the flower's center. Thisadaptation benefits both the flower (moreefficient pollination) and the bee (rapidcollection of nectar).

Station 7 _____ barnacle/whale Barnacles create a home site by attaching themselves to whales. This neither harms nor benefits the whales. _____ mistletoe/spruce tree Mistletoe extracts water and nutrients from spruce tree to the tree’s detriment. _____ yucca plant/ yucca moth Yucca flowers are pollinated by yucca moths. The moths lay their eggs in the flowers where the larvae hatch and eat some of the developing seeds. Both species benefit. _____ hermit crab/ snail shell Hermit crabs live in shells made and then abandoned by snails. This neither harms nor benefits the snails. _____ cowbird/ buffalo As buffalos walk through grass, insect become active And are seen and eaten by cowbirds. This neither harms nor benefits the snails.

Station 8 _____ mouse/ flea A flea feeds on a mouse’s blood to the mouse’s detriment. _____ wrasse fish/ black sea bass Wrasse fish feed on the parasites found on the black sea bass’s body. Bothe species benefit. _____ deer/ tick ticks feed on deer blood to the deer’s detriment. _____ cuckoo/warbler A cuckoo may lay eggs in a warbler’s nest. The cuckoo’s Young will displace the warbler’s young and will be raised by the wa

Station 9 _____ honey guide bird/ badger Honey guide birds alert and direct badgers to be bee hives. The badgers then expose the hives and feed on the honey first. Then the honey guide birds eat. Both species benefit. _____ hookworms/ humans Hookworms enter the human body by burrowing into the skin of feet. Once in the skin they enter the bloodstream and travel to the small intestine where they attach to the walls and begin to drink the person’s blood and weaken the victim. _____ kapoc trees/ orchids Types of orchids grow high on branches of tall Kapok trees of the jungle. This adaptation allows the orchid to receive enough sunlight to perform its photosynthesis but the kapok tree is unaffected. _____lichen algae/lichen fungus Lichens are close associations of fungi and algae. The fungi hold the water supply and the algae perform photosynthesis and manufacture the carbohydrates for both.

Station 10 _____ acacia tree/ants In the jungle of South America live a thorn tree called an acacia. A species of ant eat secretions of the acacia, drink its sap, and raise its young in the hollow thorns. The ants also keep competing vines from growing near the acacia tree and they help repel any insects that would damage the acacia tree. _____ moose / tapeworm In the flesh of the moose are cysts (dormant stage) of a worm that makes the muscles of the moose stiff and sore. If the moose is killed and eaten raw, the predator species will develop a form of tapeworm. _____ lactobacilli/ humans Lactobacilli are a type of bacteria that live in our lungs and destroy many microorganisms that enter our respiratory system. They are highly adapted to living in our lungs and can’t survive in many other habitats. _____ soybeans/ bacteria Soybeans require nitrogen from their environment. This nitrogen is provided by bacteria that live in special root nodules. In return, the bacteria receive some of the sugar (carbohydrate) manufactured by the soybeans.
