'Some selection-based theories propose that genome streamlining, favoring smaller genome sizes, is advantageous in nutritionally limited environments, particularly under P-limitation. To test this prediction, we conducted several experimental evolution trials on clonal populations of a facultatively asexual rotifer that exhibits intraspecific variation in genome size.'
