Data from: Parents face quantity-quality tradeoffs between reproduction and investment in offspring in Iceland
How to optimally allocate time, energy and investment in an effort to maximize one's reproductive success is a fundamental problem faced by all organisms. This effort is complicated when the production of each additional offspring dilutes the total resources available for parental investment. A...
