Free Bachelor of Science in Forestry: Wildlife Ecology and Habitat Preservation Questions and Answers

Question 1

What is the term used to describe the process of returning something to its historical location with the identical species, their original abundance, and the same patterns of occurrence?

Accepted Answer

Restoration

Answer

Ecological restoration is the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed, aiming to return it to a state resembling its historical condition. This includes re-establishing the original species composition, their natural abundance, and the ecological processes and patterns that existed prior to disturbance. It goes beyond mere conservation by actively repairing and rebuilding ecosystems.

Question 2

Interactions between abiotic and biotic factors

Accepted Answer

Ecology

Answer

Ecology is the scientific study of the relationships between living organisms (biotic factors) and their physical environment (abiotic factors), as well as the interactions among organisms themselves. It examines how these factors influence the distribution, abundance, and dynamics of life on Earth. An ecosystem, on the other hand, is a specific community of living organisms interacting with their non-living environment.

Question 3

What are the repercussions of population decline, the intrusion of non-native species, novel or modified species interactions, disrupted succession, alterations in ecosystem functions, and the loss of ecological stability?

Accepted Answer

Effects of ecological degradation

Answer

Ecological degradation refers to the deterioration of an ecosystem's health, integrity, and capacity to provide services, often resulting from human activities. The listed repercussions—population decline, invasive species, altered interactions, disrupted succession, and loss of stability—are all direct indicators and consequences of such degradation. While related to biodiversity loss and environmental change, "effects of ecological degradation" most comprehensively describes this suite of negative impacts on ecosystem structure and function.

Question 4

Capability to rapidly revert to pre-disturbance conditions

Accepted Answer

Resilience

Answer

Resilience, in an ecological context, is the capacity of an ecosystem to absorb disturbance and reorganize while undergoing change, so as to retain essentially the same function, structure, identity, and feedbacks. Specifically, it refers to the speed and extent to which an ecosystem can recover and return to its pre-disturbance state after being disrupted. This ability to bounce back is crucial for ecosystem health and persistence.

Question 5

The capability to withstand alterations away from pre-disturbance conditions

Accepted Answer

Resistance

Answer

Ecological resistance is the ability of an ecosystem or community to resist or prevent changes in its structure, composition, or function when subjected to a disturbance. It describes how much a system can withstand before it begins to change significantly. A highly resistant ecosystem will show minimal alteration even when faced with considerable stress or disturbance.
