Question

Which one or more options is/are example(s) of niche partitioning between species?

• A. Temporal separation of activity
• B. Diet specialization
• C. Hybridization
• D. Vertical stratification of foraging heights

Hint:

The BSC is powerful for studying living, sexually reproducing organisms but fails for asexual organisms, fossils, and cases with frequent hybridization. Always consider alternative species concepts (morphological, phylogenetic, ecological) in such contexts.

Answer 1

The Correct Option is A, B, D

Step 1: Define niche partitioning.
Niche partitioning is a process by which coexisting species minimize competition by using different resources, or the same resource in different ways, times, or spaces. This promotes coexistence in an ecosystem.

Step 2: Evaluate options.
(A) \emph{Temporal separation of activity.}
Yes — if two species are active at different times of the day or seasons (e.g., one nocturnal, one diurnal), they avoid direct competition. (B) \emph{Diet specialization.}
Yes — if species focus on different food types or prey sizes, they reduce dietary overlap and competition. (C) \emph{Hybridization.}
No — hybridization is interbreeding between species and does not reduce competition for resources; in fact, it blurs species boundaries rather than partitioning niches. (D) \emph{Vertical stratification of foraging heights.}
Yes — many bird and insect species partition habitats vertically (canopy vs understory vs ground), reducing direct competition. Final Answer:\quad \(\boxed{\text{(A), (B), and (D)}}\)
