Question

20.2. articulate the role of relative species abundance and species richness in defining ecological diversity.
currently, the red deer population in scotland has an adverse impact on both tree and bird populations in the ecological communities within the scottish highlands. if the scots decide to reintroduce wolves into the scottish highlands, which of the following attributes of the bird populations will most likely increase?
correct answer(s)
bird abundance bird diversity
bird predators bird beak size
bird calls bird richness

Explanation:

When wolves are reintroduced, they will predate on red deer. This will reduce the red deer population. With fewer red deer, there will be less negative impact on tree populations. More trees mean more resources (like nesting sites, food from insects on trees, etc.) for birds. This will likely lead to an increase in the number of birds (bird abundance). Also, a more stable and resource - rich environment (due to reduced deer - induced stress on trees) can support a greater variety of bird species (bird richness) and overall bird diversity.

Answer:

bird abundance, bird diversity, bird richness
