During the study, environments lacking plentiful food were male-skewed, with 78 percent of sea lampreys becoming male after three years, whereas environments more conducive to growth produced only 56 percent males. Scientists predicted new hard and superhard ternary compounds September 4, The finding that a life-history trait like growth rate affects sexual development makes sense.
Slower sea lamprey growth rates during the larval phase of development may increase the odds of sea lampreys becoming male, according to a USGS study. Release Date: March 28,
