    Greeff, Jaco M. (Jacobus Maree); Newman, D.V.K. (Duncan Victor Kimberlin) (Elsevier, 2024-01)
    In some species, females vary in the numbers of times they mate. While polyandry will always be beneficial to a male that mate with a previously mated female, the effect on female fitness is unclear. From females' perspective, ...
