...For example, females are larger than males in many fish species, perhaps because of the requisite energetic burdens of producing massive amounts of roe, and elevated testosterone increases body size. Thus, as Mank writes: "The benefits of increased body size to roe production and mate selection may, at l...NSF funds biofertilizer research at Rutgers-Camden
