Current observations of insular species response to climate change generally report geographic range shifts/reductions for species and vegetation associations in addition to resulting impacts on local ecology . These include changes in plant/animal phenology and resulting community alterations such as for the common Mediterranean island species Quercus ilex  and Ficus carica . Species have been shifting greater distances to access not only suitable climate conditions but also, by association, suitable breeding conditions and seasonal food. Examples include: migratory birds such as Coturnix coturnix now having earlier spring arrival dates in the Mediterranean compared to six decades ago and the increased mortality of the iconic Argyroxiphium sandwicense  as result of warmer drier trends at Hawaiian high altitudes . There have also been die-offs of some species from temperature extremes  within the Pacific islands .
