This was a question on the exam.
There is species A and species B. They both feed on nectar. Species A feeds only during the day and Species B feeds only during the night. There is competition between A and B as their niche overlaps slightly. Both A and B can feed during day AND night if there was no competition.
There is a graph with the x axis being Time (from day to night) and Y axis being number of Nectar visits (or nectar use).
Species A has a much higher level of nectar visits than Species B and their niches overlap slightly.
Would this be an example of niche differentiation or competitive exclusion?
I first thought niche differentiation because A and B are using the nectar at different times to avoid competition,
but at the same time, the niche of A and B overlaps slightly and species A has greater nectar use than species B.
This would be a form of asymmetric competition and competitive exclusion would sound more likely.
