Information about symbiotic relationships and mutualism in the rainforest. Section 3 concentrates on the diversity of the tropical rainforest. Symbiosis- the interaction between two organisms that benefits one or both Mutualism- when both organisms in the symbiotic relationship benefit from the. Symbiotic relationships appear to be the rule and not the exception in the rainforest All tropical rainforests are characterized by tremendous biological.

The fungi normally contain insecticides as a defense mechanism, but when in the garden, they degrade these toxic compounds, removing them from the fungal tissue eaten by the ants.

Recently, it has been realized that the ant-fungal association is even more complex. But when the garden is stressed, or if the ants are removed, the Escovopsis fungi explode in numbers and overwhelm the fungal garden. Then the ant population will decline due to lack of food, at least until another garden can be established. It appears that still other compounds produced by the ants may act to inhibit the growth of alien bacteria and fungi which might invade the garden, although the exact roles of these secretions are not yet known Ariniello, ; Currie, Certain Passifloraceae plants have odd relationships with Heliconiine butterflies.

The butterflies lay their eggs on the tips of the plant shoots which the caterpillars like to eat.

When there are no eggs on the shoots, the plant produces yellow nectaries which mimic eggs, or other structures stipules which look like young caterpillars. Very common are highly specific relationships between a pollinator species and a plant, such as those between figs and their wasp pollinators.

Figs are dioecious, that is, they have separate male and female plants.

The male dies, and the female wasp leaves the fruit, picking up pollen from the male flower within the fig. She then flies to another tree which has young figs, and enters a fruit.

If the fig is female, and contains female flowers, pollen on her body will fertilize them; seeds will subsequently form. To survive in the rain forest, it is often useful to have some help from a species with which you are not competing. Symbiotic relationships are often broad, such as pollination of plants by insects in return for nectar.

They may also involve just two species with specific benefits, or one species with several relationships in a complex series of interactions. Types of Symbiotic Relationships Many symbiotic relationships in the rainforest are broad, across several species, such as when insects pollinate plants and get pollen or nectar as food in return. Other symbiotic relationships only involve two species and are unique.

For example certain rain forest caterpillars secrete a sweet chemical on their backs that a specific species of ant will eat. In return, the ants will protect the caterpillars. Some organisms rely on several different relationships with different species, receiving and producing benefits in each one.

For example, a Brazil nut tree relies on the orchid bees for pollination and attracts them with nectar. The tough seed pods can only be opened by a ground-dwelling rodent called an agouti that eats some of the nuts and buries others, some of which eventually become new Brazil nut trees.

Sciencing Video Vault Examples of Mutualism in Tropical Rainforest Ecosystems The complex web of interactions among the species of the rain forest often involves insects, plants and primitive organisms such as fungi. Ants are especially likely to form various symbiotic relationships.

When the capuchin monkey feeds on nectar in these flowers by lapping it up, it gets pollen on its face - which it eventually transfers to other flowers in the process of feeding on them. In this way, the trees provide the capuchin species with food, while the capuchin monkey facilitates pollination of flowers of this tree. Commensalism The relationship between ecitoninae - the New World army ants, inhabiting the rainforest floor, and antbirds - small dull-colored South American bird species, is the best example of commensalism.

These army ants are notorious for their tendency to take on anything that comes in their path while they march the forest floor. The antbirds, on the other hand, follow this swarm of ants, and feed on whatever is left behind after the ants are done with their share.

The ants manage to shake the floor as they march, which causes the insects on the forest floor to fly out. These insects are they happily snapped up by the antibirds.
