	Tullgren funnels are used to assess species richness in leaf litter [[arthropods]]. Leaf litter samples are typically placed in Tullgren funnels to sample for soil micro- and mesofauna. The Tullgren apparatus consists of a funnel, a light source, a screen, and a receptacle into which the [[animals]] fall. The sample is placed in a funnel that is lined with a screen with the light source above; the extraction process works by desiccating the soil from above via heat lamp, forcing the fauna downward through the funnel into the sampling liquid below.

	Leaf litter packs can also consist of a mesh bag, usually with 1/4 inch openings filled with a mixture of palatable organic material like fresh leaf litter and lettuce. The size in the mesh is varied based on the size of target [[organisms\|organisms]]. The mesh is large enough so target organisms can crawl into the bag, and small enough so they generally can not leave. Leaf packs should be placed on a low spot on the ground in order to maximize capture: this is where soil is most fertile, and where moisture content is highest. A small hole is dug in the ground, into which the bag is placed and then loosely covered with [[soil\|soil]] and surrounding leaves. Marking the spot with a bag is generally recommended so that the bag can be retrieved later. The leaf pack is generally left for a 1-3 days to allow organisms to get into the bag before removal. Next, you dump the leaves out of the bag onto a plate and start looking for organisms like [[slugs]], worms, centipedes, [[mites]], and smaller organisms. You can put them on a petri dish and observe the [[soil organisms\|soil organisms]] closer under the microscope to allow you to properly identify them.

	Baermann funnels are useful for measurement of microfauna and [[microorganisms\|microorganism]] abundance and richness in a soil sample. A funnel with a small mesh or muslin lining on the inside is attached via tube to the bottom of the funnel, which is clamped shut at the bottom. When the soil is placed in the funnel, it is then filled with water. Organisms like [[nematodes\|nematodes]] will move down through the soil and water, through the mesh and into the bottom of the tube. After 24 to 48 hours, the clamp is opened, allowing the organisms to drain into a petri dish. Samples can then be identified via microscopy.

	Tullgren funnels are used to assess species richness in leaf litter [[arthropods]]. Leaf litter samples are typically placed in Tullgren funnels to sample for soil micro- and mesofauna. The Tullgren apparatus consists of a funnel, a light source, a screen, and a receptacle into which the [[animals]] fall. The sample is placed in a funnel that is lined with a screen with the light source above; the extraction process works by desiccating the soil from above via heat lamp, forcing the fauna downward through the funnel into the sampling liquid below.

	~~== Leaf Litter Pack ==~~		Leaf litter packs can also consist of a mesh bag, usually with 1/4 inch openings filled with a mixture of palatable organic material like fresh leaf litter and lettuce. The size in the mesh is varied based on the size of target [[organisms\|organisms]]. The mesh is large enough so target organisms can crawl into the bag, and small enough so they generally can not leave. Leaf packs should be placed on a low spot on the ground in order to maximize capture: this is where soil is most fertile, and where moisture content is highest. A small hole is dug in the ground, into which the bag is placed and then loosely covered with [[soil\|soil]] and surrounding leaves. Marking the spot with a bag is generally recommended so that the bag can be retrieved later. The leaf pack is generally left for a 1-3 days to allow organisms to get into the bag before removal. Next, you dump the leaves out of the bag onto a plate and start looking for organisms like [[slugs]], worms, centipedes, [[mites]], and smaller organisms. You can put them on a petri dish and observe the [[soil organisms\|soil organisms]] closer under the microscope to allow you to properly identify them.
