Question

How does juniper demonstrate the concepts of disturbance and succession? What is the climax species and natural disturbance regime in this ecosystem?

Answer 1

In this ecosystem disturbance is a force the plays a vital role in shaping the structure of populations and also the character of entire ecosystems.

It consist of two types of disturbance:Minor disturbances and major disturbances.Minor disturbance includes droughts,floods and major disturbance include tsunamis,earthquake etc

Disturbance mainly causes changes in spatial designing in the ecosystems and brings morality to organisms.The disturbance mainly depends upon its frequency,size of the patches and also its intensity.

Succession is a change in an ecosystem of species over time.This change is mainly due to the composition of species that comes in series of modification in structure and function of species community

Succession involves in changes in a forested area.When the forest area is no longer grazed the seeds or grains of shrubs and trees starts growing.The species involved in the composition in the forest continues to develop until it get dominated by a stable ,self maintaining species.This group of species are called climax species or climax community.It is final stage of succession and its very stable stage that can remains for more than 100 years

Two types of succession involved primary succession and secondary succession.

Primary succession occurs in a landscape,plants invaded and a biological recovery was performed across the regions which is incapable of sustaining the life.It mainly begins in barren areas such as barren rocks.Each successive stages that modifies the habitat by the composition of soil and reducing the amount of shade.

Secondary succession which causes a disturbance in a area that is existing communities of organisms in ecological succession i.e clear cut logging operation. Common plants during this stages are raspberries ,cherry trees etc.

In climax communities the misconception are permanent and frozen in time and natural disturbances can be wind damage from a hurricane,insect attack or even logging ,forest fire etc.These disturbances make the community bck in to an earlier succession stage which result in restarting the process of ecological succession .

The time dependent responses in horizontal sediment fluxes and associated contaminant fluxes were sensitive to variability in time of disturbance and it also causes disturbance in long intervals that allow the woody plants to become large , dominant and crown fire that reduce or decrease woody plant cover.
