ESPM 111 Ecosystem Ecology. Succession. • Primary Succession. – After severe disturbance that re move or bury products of the ecosystem. • Secondary Succession. – After disturbance on a vegetated site. Most above ground live biomass may be disturbed but soil organic matter and plant propagules remain. • Gap Phase Succession.

Primary succession describes the establishment of new ecosystems through the colonization of barren substrates (Odum, 1969). Bacteria are typically the first colonizers, which initiate key processes that enable ecosystem establishment and provide resources for fungi, plants, and animals to colonize later.

This way, students have a visual record of how succession works and have fun while they create the record. Begin by giving a short explanation of succession and defining the two main types of succession: primary and secondary succession. Give students a template on which they can draw their successional timeline and colored pencils or crayons.

s of ecological succession: primary succession and secondary suc-cession. In primary succession, a site that is initially absent of species becomes colonized for the very first time. In secondary succession, a site that supports an existing assemblage of s ecies experiences a disturbance that changes the composition of spe-cies.

Abstract. Over time scales of thousands to millions of years, and in the absence of rejuvenating disturbances that initiate primary or early secondary succession, ecosystem properties such as net primary productivity, decomposition, and rates of nutrient cycling undergo substantial declines termed ecosystem retrogression.

There are two types of ecological succession – primary and secondary succession. Primary succession is the establishment of a community in an area of bare rock that does not have topsoil. For example, suppose a lava flow alters an ecosystem. The lava hardens to form bare rock. Usually, lichens begin to grow on the rock first. Because lichens and …
