Una biodiversidad reducida y un número alto de endémicos caracterizan los ecosistemas insulares. Especies nativas y endémicas de islas son consideradas más vulnerables que las especies continentales a la invasión de especies exóticas y a cambios en el hábitat. El efecto de reemplazar bosque nativos por plantaciones exóticas de especies maderables fue estudiado en el montaje de especies nativas y endémicas de hormigas. La hipótesis principal consistió en que las especies endémicas y nativas eran más vulnerables a cambios en el hábitat que las especies de hormigas exóticas. Sin embargo, se encontró que las hormigas nativas fueron más numerosas y diversas, tanto en bosques nativos como en las plantaciones exóticas. También apareció un número alto de dos especies endémicas dentro de plantaciones de exóticas, mientras sólamente una especie de hormiga exótica Hypoponera opacipeps fue relativamente abundante, particularmente en bosque nativo. En conclusión, las especies de hormigas exóticas no dominaron las comunidades estudiadas, ni tampoco parecieron impactarse negativamente las especies nativas y endémicas por el reemplazo del bosque.
