Ants prefer salty snacks to sugary ones, at least in inland areas that tend to be salt-poor, according to a new study published this week in the journal Proceedings of the National Academy of Sciences.
Ecologists from the University of California, Berkeley, the University of Arkansas at Little Rock (UALR) and the University of Oklahoma tested the salt versus sugar preferences of ants from North, Central and South America, using ant populations at varying distances from the ocean. While ocean spray and storms can spread salt tens of miles from the coast, areas farther inland are often deprived of salt, and the researchers suspected they might find different taste choices between coastal and inland ants.
