Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Climax theories in plant ecology explain the final, stable stage of vegetation succession that develops in a given geographical region.
Step 2: Detailed Explanation:
- The Mono-climax theory was proposed by the American ecologist Frederic Clements in 1916.
- Clements argued that for any given climatic region, there is only one stable, ultimate vegetation community (the climax) toward which all successional pathways eventually converge, regardless of the initial soil type or topography.
- According to this view, climate is the sole dominant factor determining the climax.
- Arthur Tansley later countered this with the Poly-climax theory, arguing that local factors like soil (edaphic) or topography can produce multiple stable climaxes in the same climatic zone.
Step 3: Final Answer:
The mono-climax theory was proposed by Clements.

Statement (II): Terminalia arjuna tree is not a regular component of forest stand and is usually worked under selection and coppice with standards.
Choose the correct answer from the options given below: - The most important single factor affecting natural regeneration of Shorea robusta is the time lag between the falling of seed and the commencement of the ________.
- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
