Oceanic islands

• There is a high proportion of endemic species, increasing probability of new medicines
• They are key foundations for coral reefs, they change ocean nutrients therefore retrieving nutrients from deep seabeds
• They are important for isolation and biodiversit, the isolated location causes difficulty when species attempt to colonise.
• Many species colonise due to chance
• Species that colonise gradually evolve so they become adapted to local ecological niches
• Due to low biodiversity, there can be absent taxa
• There is a lack of mammal predators due to difficulty colonising
• There is a high exploitation of species for resources
• Introduced species are a threat due to the lack of predators. Species on the islands are not adapted to new predators
• Introduced plants can often outcompete indigenous species
• Sea level rise is a threat
• Habitat change or destruction including urban, agriculture or tourist development cause damage.
• Eradication of introduced species can conserve the habitat
• Laws/legislations can be established to conserve the habitat
• Quotas/net mesh size can be controlled preventing overexploitation
