A population of rabbits with typical variations of traits lives in a meadow with a
depression that runs through the middle. overtime, the depression fills with water
and becomes a river, separating the one population into two over a period of
several years. This is an example of:<\/p>\n\n\n\n

species present and the relative abundance of the species present?
a. biodiversity index
b. species evenness
c. shannon’s index
d. hardy-weinberg index
e. species richness – correct answerc. Shannon’s index
Loblolly pine requires a minimum temperature to grow and thrive. Under current
