If anyone sees this question can they help me out? When studying the genetic diversity of a bird species on an island compares to that on the mainland what best describes the relationship between the two populations of birds on the mainland and the island

(A) the mainland population will have increased genetic diversity due to a reduction in competition from the birds that flew to the island

(B) the island population will have reduced genetic variability due to a smaller gene pool present in the foundinh members of the island population

(C) the island population will have increaed genetic variability since the birds have acess to increased food supplies that are not present on the mainland

(D) the mainland population will have decreased genetic diversity because the founding members of the island population were those with the greatest evolutionary fitness

Chinese privet is a plant that is native to china. over 150 years ago, chinese privet was introduced to the united states as a fast-growing shrub that serves as an excellent privacy hedge. with no natural herbivore, chinese privet quickly established itself and spread in natural areas throughout the southeast and eastern seaboard of the united states. its dominance in these areas has jeopardized the survival of native plant species. chinese privet provides evidence that introducing non-native organisms can cause environmental damage integrated pest management strategies will not decrease chinese privet populations american gardeners can easily control the spread of chinese privet non-native plant species have type i survivorship curves
