A number of scientific journals are running stories in their November issues about species that routinely consume alcohol as a part of their diet. Naturalists argue that it would be strange if animals were to avoid naturally-occurring sources of alcohol, such as rotting fruit. The topic got a fresh airing in specialist titles, such as Science Daily or the news pages of Phys.org, as well as UK dailies such as The Independent and The Guardian.
The impetus for the current editorial interest comes from Trends in Ecology and Evolution. The journal collates behavioural observations from past years, to make a strong argument for removing anthropocentric assumptions about alcohol and the routine overlooking of certain aspects of dietary intake in wild populations. For instance, levels of Alcohol By Value (ABV) can top 10% in over-ripe palm fruit, while ethanol can be routinely detected in 29 of Costa Rica’s 37 fruits routinely eaten by the country’s frugivores.
