In biology, a climax community is a vegetation community that is the final stage of a successional process, the end result of which is a stable ecosystem in which all available niches are filled by species well adapted to the environment. A climax community is therefore an ecologically mature community that is in equilibrium with its environment, and is able to sustain itself over the long term without undergoing significant changes.
The concept of a climax community was first proposed by the ecologist Frederic Clements in the early 20th century, who believed that plant communities underwent a series of predictable stages of development, culminating in a stable, self-sustaining ecosystem. This idea has since been modified and refined by other ecologists, who have recognized that ecosystems are often more complex and dynamic than Clements' model suggests. Nonetheless, the concept of a climax community remains an important one in ecology, as it helps to provide a framework for understanding the long-term stability and resilience of ecosystems.
Climax communities can be found in a variety of different ecosystems, including forests, grasslands, and wetlands. In a forest ecosystem, for example, the climax community might be a mature hardwood forest, with a diverse mix of tree species that are well adapted to the local climate and soil conditions. Similarly, in a grassland ecosystem, the climax community might be a tallgrass prairie, with a mix of grasses, wildflowers, and other herbaceous plants that are adapted to the local climate and soil conditions.
There are several factors that can influence the development of a climax community, including climate, soil type, and the presence of disturbance events such as fires, hurricanes, or drought. For example, in a forest ecosystem, the type of trees that dominate the climax community will depend on the local climate, with warmer, drier climates tending to support more drought-resistant species, and cooler, wetter climates supporting species that are more tolerant of moisture. Similarly, the type of grasses and other plants that dominate a grassland climax community will depend on the local soil type and climate, with different species being better adapted to different conditions.
Overall, the concept of a climax community is an important one in ecology, as it helps to provide a framework for understanding the long-term stability and resilience of ecosystems. By understanding the factors that influence the development of climax communities, ecologists and conservationists can work to protect and preserve these important ecosystems, ensuring that they remain healthy and productive for future generations.
Climax Community
The correct answer is B. A climax community is the final stage of succession, remaining relatively unchanged until destroyed by an event such as fire or human interference. In a closed-canopy forest, little light hits the ground. It gets recolonized after the destruction. After a disturbance, new species of plants and animals might occupy the habitat. Explanation: Gradually larger and larger plants involve the environment alongside a decent variety of animals.
What could possibly change a climax community? A once thriving climax community is destroyed, leaving the area devoid of life. Primitive communities are common in areas undergoing primary succession. Mangrove forests are dependent on hurricanes to remove colonizing species that without disturbance have the potential to outcompete mangroves. Climate conditions determine what sort of plant communities can survive, leading to the complex ecological relationships and widely varied niches that are the definition of a climax community. In the forest, there are complex ecological relationships for predators and their prey and a wide variety of niches for all plant and animal species. In soil, the rhizosphere, fecal matter, and decomposing plant tissue are important examples of this type of habitat Blackwood and Paul, 2003.
So, on reaching climax, the net productivity becomes stable. Eventually, enough soil forms and enough nutrients become available such that a climax community, like a forest, is formed. Primary succession Succession on newly exposed substrates such as a sandbar or rubble at the foot of a receding glacier. The interested reader is referred to Ehrlich and Roughgarden 1987 and Blackburn and Gaston 2003 for a discussion of these issues. What is an example of a climax species? Complete answer: The climax community remains stable as long as the environment remains unchanged. Hint: During succession over the rocks, the lichen gets replaced by forests.
The process commences wiā¦ primary succession , primary succession prisere A succession initiated on a newly produced bare area e. A climax community is the last stage in succession, a stage where an ecosystem reaches a stable state. The sequence of seres for a given region is often fully predictable, both with respect to the general types of population expected at each sere and to seral durations. Enrichment phenomena increase available nutrients, such as by release from litter layers and humic materials through burning. If the original physical environment is sand then the sequence of seres includes: soil- forming organisms bacteria, lichens, mosses, fungi , annual grasses, perennial grasses, shrubs, and trees Fig.
It is an ecological community that has reached the final stage of ecological succession. This is the generalāand admittedly simplifiedāidea of succession, and this large forest and all the critters that call it home is the climax community. Examples Though a true climax community is difficult to achieve in nature, there are a few examples we can observe. Which is an example of a climax ecosystem? How does a climax community differ from a successional community? This allows fugitive species to depend entirely on the presence of minor habitats with relatively quick turnover rates. However, a moderate level of disturbance, physical or biotic, results in the highest species numbers Figure 12.

Ecological succession is the appearance and disappearance of communities in regular succession in a particular area until a final stable community emerges. He was among the first to consider that plants go through a process of inhabitation in an environment beginning with simple, shallow-rooted plants and eventually maxing out with vascular plants best suited for the climate of the area of inhabitation. Why are climax communities rare in the world? In Queensland, Australia, the Daintree Rainforest is another example of a climax community. Disturbances to Climax Communities There are many things that can disturb or even destroy a climax community. Complex community interactions between plants, animals and decomposers have established themselves to cycle energy and nutrients.
What is an example of a climax community? [Solved!]
According to this theory, climate is only one of the several factors, any of which may have a controlling influence on the structure and stability of the climax. The rocky face of a mountain that suddenly has moss growing on it or volcanic rock that breaks down enough to allow for tiny plants to become established are examples of primary succession. While primary succession can last thousands of years, secondary succession may take less than a century because of slightly more hospitable resources. Ecological succession is not guaranteed to stop in any area due to the possibility of natural disasters, climate change, and disease. According to this theory, climax communities are patterns of populations varying according to the total environment.
This could be a natural disaster, like a major fire, or human interference. Approximately how long does it take secondary succession to reach a climax community? For example, the structure of a metapopulation e. Whereas the mono-climax theory allows for only one climatic climax in a region and the poly-climax theory allows several climaxes, the climax-pattern hypothesis allows a continuity of climax types varying gradually along environmental gradients and not clearly separable into discrete climax types. Species coexistence was only thought possible with minimal niche overlap Cody, 1981; Diamond, 1978; Hutchinson, 1959. Each plant species survives on its own merit and not as part of a common goal of a diverse climax community. What are two things that can disrupt a community? What is the end stage of the climax? How does climax community differ from immature community? But they break down if it is not, and there is little evidence so far that they are. Disturbance Major alternations in vegetation due to events such as wildfires, hurricanes, landslides, and human clearing.
Everything in the climax community is stable and balanced. This end stage is called the climax, and the plants, animals, and other organisms that live in this ecosystem are called the climax community. How long does it take to reach a climax community? The initial model of a single climax community has been shown to be inaccurate. If previously cultivated land is the starting condition, i. The climax community is when a stable state is reached, where there is high biodiversity and a number of new species. Weaver and Clements 1937 have described a number of stages through which an area covered by deep water is transformed into a forest. The time required for soil development and recovery of soil populations such as decomposers and mycorrhizal symbionts can often delay recovery of plant communities Allen et al.
In a climax community, the plants and animals are in balance with each other and their environment. They have high species diversity, and transfer of energy is in the form of complex food webs, not simple food chains. This community is unique not only because it is so large, but also because it spans so much of the continent that it reaches the coast in certain places. Examples of climax species include the white spruce Picea glauca , coast redwood Sequoia sempervirens , etc. How is a climax community different than a primitive community? So, the changes that occur due to the succession in that area are known as sere. The idea of a climax community is not currently accepted by many ecologists, the scientists who specialize in ecology.
