Look at our forum discussion — Sexual vs Asexual Reproduction differences. In order to develop conceptual clarity on pioneer species, it is imperative to understand the concept of ecological systems, the development of ecological communities, and ecological successions. Ecological systems entail the biological interactions between the different elements of the natural system and their varied interrelations.
The way this system is built determines how an ecological system will function, its basic requirements, sustainability, and prosperity. How they influence each other determines the balance of that community. Ecological succession encompasses all factors, processes, and interrelationships within a community governing its evolution over time.
Primary succession is the succession that takes place in an area where no other organism has previously lived, thrived, and reproduced. Therefore, the pioneer species in primary succession has to necessarily be a plant — a photo-auto-lithotroph. They colonize the bare substrates no soil and develop ecological communities thereafter. Thus, examples of pioneer species responsible for primary succession are limited to them.
Areas affected by major landslides, fires, volcanic eruptions, or flooding suffer apocalyptic habitat destruction.
Such areas witness even erosion of the topsoil and the layers beneath. Hence, a lot of these pioneers are nitrogen-fixing.
This re-establishment is the secondary succession. In these areas, some proportions of soil and previously occurring vegetation is remnant. These areas encounter fewer fights for resources and pioneer species here are more privileged. If asked what is a pioneer species in secondary succession , we can list out angiosperm trees and shrubs. Climax is controlled solely by the environmental factors and sometimes, by the community composition immediately preceding it.
