Question

conservationists have studied a region in biodiversity on both a genetic level and a species level for two forested areas in the southeast. a model of the size and separation of the forested areas is shown here. what solutions might the conservationists propose in order to maintain or increase the genetic diversity and the species diversity within those forested areas? select all that apply. a habitat corridors could be created to promote interactions between the two forested areas. b fencing could be installed around each area to prevent migration of the animals out of the area. c breeding programs could be used to increase the gene flow for the species within the protected areas. d nonnative species could be planted at the borders of the areas to increase the number of species in the area. e enforcement of animal hunting and tree cutting regulations to ensure that endangered species are not further reduced in number

Explanation:

To maintain/increase genetic and species diversity:

• A: Habitat corridors connect areas, enabling species migration and gene flow (boosts diversity).
• C: Breeding programs increase gene flow within protected areas (enhances genetic diversity).
• E: Enforcing hunting/tree-cutting rules prevents loss of endangered species (preserves existing diversity).
• B: Fencing restricts migration, reducing gene flow (harms diversity).
• D: Nonnative species often outcompete natives, decreasing diversity (harmful).

Answer:

A. Habitat corridors could be created to promote interactions between the two forested areas., C. Breeding programs could be used to increase the gene flow for the species within the protected areas., E. Enforcement of animal hunting and tree cutting regulations to ensure that endangered species are not further reduced in number
