Analyses of historical and current threats indicate that IAS and disease have been the primary drivers of insular extinctions in modern history . Impacts of IAS on islands are projected to increase with time due to synergies between climate change and other traditional drivers such as increasing global trade, tourism, agricultural intensification, overexploitation and urbanisation . Changing climate conditions may not necessarily increase the rate of IAS introductions but is expected to improve chances of IAS establishment via  altering IAS transport and introduction mechanisms,  increasing the impacts and distributions of existing IAS and  altering the effectiveness of existing control strategies . These are likely to enhance IAS impacts on islands including: restructuring of ecological communities leading to declines and extinctions/extirpations in flora and fauna, habitat degradation, declining ecosystem functioning, services and resilience and, in extreme cases, potential community homogenisation  . Given the high degree of endemicity within oceanic islands and their associated vulnerabilities, such exacerbation by changing climate poses a serious threat to decreasing global biodiversity  .
