Why do some organisms within a single species have many offspring, while others have relatively few? A new study led by University of Minnesota researcher Emilie Snell-Rood finds that access to some nutrients may be a star player in shaping traits related to fitness such as fecundity and eye size over the long term. Given drastic increases in the availability of many nutrients due to the widespread use of fertilizers and road salts, the finding has important implications for agriculture and ecology.
