You are a consultant for the government on the small island nation of Aggielandia in the south Pacific, which has a total forested area of 80km². The government is considering a proposal for growth of the tourism industry on the island that would convert an 75% of the island into habitat that is unusable by forest-dependent species. Armed with the current species-area curve for forest-dwelling lizards in Aggielandia, estimate the number of species that would go extinct if the proposal goes forward. Number of forest dependent species 25 20 15 10 20 S=CA0.23 40 60 Area (km²) 80 100

You are a consultant for the government on the small island nation of Aggielandia in the South Pacific, which has a total forested area of 80 km². The government is considering a proposal for the growth of the tourism industry on the island that would convert 75% of the island into habitat that is unusable by forest-dependent species. Armed with the current species-area curve for forest-dwelling lizards in Aggielandia, estimate the number of species that would go extinct if the proposal goes forward. **Graph Explanation:** - **Horizontal Axis (X-axis):** Represents the Area in square kilometers (km²) from 0 to 100. - **Vertical Axis (Y-axis):** Represents the Number of forest-dependent species from 0 to 25. - **Data Points:** Black squares plotted on the graph, showing the number of species relative to the forested area. - **Curve:** A dotted line representing the species-area relationship, indicating how the number of species increases with the area. - **Equation:** \( S = cA^{0.23} \) - This is the species-area relationship formula, where \( S \) is the number of species, \( c \) is a constant, and \( A \) is the area. Based on this graph and curve, you can estimate the impact on species if the forested area is significantly reduced due to the proposed tourism development.
