Nov 22, Many species of ants live in symbiosis with plants, and both partners in Squamellaria is made up of epiphytic species that grow on trees. Tillandsia bourgaei growing on an oak tree in Mexico. An epiphyte is an organism that grows on the surface of a plant and derives its moisture and. An example of a beneficial, plant-plant relationship familiar to many gardeners is For example, mosses can be epiphytic, growing harmlessly on tree trunks.

Reproduction is a benefit of living high in the tree canopies. Wind, insects, and birds are all important factors in reproduction of most plants. The canopy is the liveliest place in the rainforest with hundreds of birds and thousands of insects.

The more organisms that come in contact with the epiphyte, the more likely that it will be pollinated and its seeds distributed. The wind is also very important to most epiphytes.

Orchid epiphytes have adapted to have hundreds of thousands of seeds that measure in microns that are able to float in the air over long distances and find a landing spot in another tree. Micro-ecosystems Epiphytes make up a huge part of the biodiversity in a rainforest. Not only do epiphytes account for a large portion of foliage in rainforest, they also support other plants and organisms. Every epiphyte is a microhabitat, in which there can be a food web of arthropods and other animals.

Non-vascular epiphytes such as bryophytes, liverworts, and mosses, can be a home for many arthropods. Young forests will accumulate dense coverings of these epiphytes on the bark and on the branches.

In old growth forests, epiphytic mats are formed from years of growth and the accumulation of particles and dead tissue. These mats tend to contain insects including mites, springtails, beetles, ants, moth larvae, thrips, bark lice, wasps, and spiders.

The insects thrive while living in the epiphytes in the rain forest canopy, but when they die they help to supply the epiphytes with nutrients and minerals Yanoviak An example of a vascular epiphyte that can host a microhabitat is a tank bromeliad. Tank bromeliads have stiff upturned leaves that create a cup that collects and holds water. Some tank bromeliads have been found to hold up to two gallons of water when completely full in which the plant can use as a water supply and a source of nutrients.

Being able to collect water is important to the plant, but the small pool of water is also important to many unique species that depend on the bromeliad. Frogs, mosquitoes, flat worms, insects, snails, salamanders, and crabs can all be found inside the water of a tank bromeliad. Some poison dart frogs use the plant to raise their young due to pooled water and supply of insects and larvae. The female frog lays her eggs on the forest floor, and when the eggs hatch she carries the tadpoles up to the epiphyte.

Epiphytes are also a home to ants, including the stinging ant. Certain Bromeliad epiphytes contain chambers that are connected by holes and tunnels. The chambers give a place for the stinging ants to live, store food, and reproduce. Not only do the ants benefit from the situation, but the bromeliad benefits too. The ants protect the plant from insects and animals that would eat the leaves and also supply the plant with nutrients.

Wastes from the ant colony decay and the bromeliad is able to absorb the nutrients so that it can live and grow in the canopy. Another group of animals that are greatly benefited by epiphytes are birds because of the many resources that epiphytes have to offer. Resources that epiphytes provide are flowers, nectar, fruits, insects, water, and material to use to build nests.

It was found that over species of birds use epiphytes to obtain food and nutrients.


Frugivores, insectivores, and nectarivores all rely on epiphytes for food along with many species of birds that use epiphytes for nesting. The most common birds that use epiphytes are tanagers Thraupidae and hummingbirds Trochilidae. A study showed that 60 percent of birds in an area used epiphytes in foraging, showing that epiphytes are responsible for supplying a large amount of food to bird species Nadkarni Researching the Canopy Even with systems to explore the rain forest canopy that have been developed through the years, it is extremely hard to explore the canopy.

By using platforms, cranes, walkways, and ropes, scientists have tried to explore the huge amount of diversity contained in the forest crown and in the epiphyte layers. The most efficient way off finding what arthropods that are supported in the tree canopy and in the epiphytes is by fogging. Insecticide is sprayed into the canopy, killing arthropods and causing them to fall off of leaves and branches to the ground where they are collected.

With this method, researchers are able to test many sites that would be challenging to test other ways, but can pose many problems too. Only part of the insect population makes it down to the bottom of the trees.

Studies show that many small insects caught in the epiphytes and populations are never documented Yanoviak To get more accurate measures of the epiphytes and the organisms that rely on them, researchers must be able to reach the canopy themselves. The tree casts shade, providing habitat for a shade-loving groundcover, and the groundcover in turn keeps more deep-rooted and competitive grasses at bay. One interesting group of plants are the epiphytes.

Relatively rare in temperate regions, epiphytes are quite common in tropical rainforests. An epiphyte is a plant that grows on another plant, neither harming nor helping it. For example, mosses can be epiphytic, growing harmlessly on tree trunks. More exclusively epiphytic plants are the bromeliads and some orchids.

Bromeliads are plants that commonly grow high in the branches of tropical rainforest trees. They are often found in the joint where a branch meets the trunk; there, fallen plant debris collects, providing a source of nutrients to the bromeliad. Some species of bromeliad have cup-shaped leaf rosettes.

The cup fills with water during the frequent rains, and the plant is able to use this supply to fill its water needs. Though bromeliads perch in the branches, they do no harm to the tree. They simply perch there, high in the canopy, where light is more plentiful than on the forest floor. Epiphytic orchids can also be found perched in trees in the rainforest; like bromeliads, they collect nutrients from organic debris.
