Projecting the impacts of climate change to an entire endemic flora is complicated by scarce and variable distribution data.
Relevant research focusing on the paediatric setting is still scarce, of variable quality and predominantly focuses on Latino populations in the USA [ 26- 29], indicating further research needs in Europe.
Food resources available to vultures in the Canary Islands before the arrival of domestic animals were scarce and variable since they would have consisted only of the remains of seabirds and sea mammals, or of rodents [ 50, 52].
