And if deserts aren't the first steps in the evolution of an ecosystem who's peak development is made up of say, hardwoods for example, then what would … They are stable for a long time, with the same species maintaining their population . In wetter climes, plants compete for light so we see a high percentage of ground cover for light interception. I've never seen a desert before.I've been reading a little about old growth forests and found this illustration, which outlines the progression of an ecosystem to climax community:When I first saw this, I thought that deserts were the first couple of sequences in this progression, with, for example, trade wind deserts being the first "pioneer" sequence, and cacti deserts being an example of the second or third sequence.
Bacteria or seeds of colonizing species find a foothold where a microclimate offers a pocket of increased moisture and protection. the community will constantly evolve and change. I thought that desert plants would evolve over time, dying and enriching the soil, making bigger plants that would change the climate of the region, and so on until those deserts were dense forest and no longer arid and dry.

Q. The desert climate (in the Köppen climate classification BWh and BWk), is a climate in which there is an excess of evaporation over precipitation. it goes through a major change called "climax" every few hundred years. And if deserts aren't the first steps in the evolution of an ecosystem who's peak development is made up of say, hardwoods for example, then what would those first steps be called and when did they happen? When a stable community, which is not the climatic or edaphic climax for the community, is maintained by the disturbance of man or his domestic animals, it is called as dis-climax (disturbance climax) or anthropogenic subclimax (man- generated).

I assume right after the Pleistocene, but what would they have been like?Succession does look like the topic I should read about.

She holds a Master of Science in wildlife management from Iowa State University.

if one species dies, a new species will fulfill the same role.

Precipitation can vary among deserts as well, from arid climates with no precipitation, to those with an annual wet season, to semi-arid ecosystems that receive slightly more precipitation.
Who is behind … Climax communities represent species assemblages that are relatively stable, unless the ecosystem is perturbed. Desert biomes, defined by low annual precipitation, cover one-fifth of the planet. Covering 14.2% of earth's land area, hot deserts are the most common type of climate on earth after polar climate. There are losts of lions tigers and bears that rome the land. She was once charged by a grizzly bear while on the job.Climate change and other factors have led to increased fire frequency in many desert areas. Under the umbrella term desert are some of the hottest and coldest places on Earth.

Primary Desert … 900 seconds . But I just read an article mentioning that the Sonoran Desert is a climax community. Directed by Ram Gopal Varma.

Resistance to invasion and resilience in the face of fire depend on water and resource availability and the speed with which native communities become reestablished.Desert ecosystems can be disturbed by fire, flash flood scouring or land clearing.

The couple runs for their life and reaches a small town only to know there are more dangerous situations are in store for them. If the disturbance is great enough, secondary succession may produce an entirely different climax ecosystem. The climax community of a grassland is very big and scary. This is expressed as leaf area index - the total area of photosynthetic leaf area divided by the area of ground surface. For example, in the southwestern deserts of North America, it can take 76 years to establish perennial plant cover and 215 years for full ecosystem recovery. We also usually see a vertically structured community and a …
