FIGURES 11–12 in Two new species of Gyrodactylus von Nordmann, 1832 (Monogenoidea: Gyrodactylidae) parasitizing introduced poeciliids in Patagonia
FIGURES 11–12. Comparison of marginal hook hooklets among the two new species from Patagonia Argentina (solid line) and the most similar neotropical Gyrodactylus especies (broken line). 11. Gyrodactylus decemmaculati n. sp. and the overlapping hooklets. 12. Gyrodactylus breviradix n. sp. and the overlapping hooklets.

FIGURE 13. Maximum Likelihood method based on the Tamura-Nei model. The tree with the highest log likelihood (- 3376.1634) is shown and distances were estimated using the Maximum Composite Likelihood (MCL) approach, and then selecting the topology with superior log likelihood value. Branch lengths are measured as the number of substitutions per site. The analysis involved 25 nucleotide sequences.

FIGURE 14. Blue line: Distribution of pairwise distance comparisons within species of gyrodactylids (without putative new ones) and between species (red line). Black dots represent de pairwise distance of newly proposed species (intraspecific), and green dots represent the pairwise comparisons of putative species with other gyrodactylids (interespecific).

Data from: Costs and benefits of polyandry in a placental poeciliid fish Heterandria formosa are in accordance with the parent-offspring conflict theory of placentation
In viviparous species, a conflict over maternal resource allocation may arise between mothers and embryos, between siblings, and between maternal and paternal genes within an embryo due to relatedness asymmetries. We performed two experiments to study the effects of polyandry and brood relatedness on offspring growth in a placental fish (Heterandria formosa). Polyandry was beneficial as it increased the probability of pregnancy, possibly to avoid genetic incompatibility. However, females mated to four males produced offspring that had a longer maturation time than those of monandrous females. When within-brood relatedness was manipulated, the size of the newborn offspring decreased with time in low relatedness treatment, while in highly related broods offspring size was constant. Low within-brood relatedness may lead to less cooperative offspring in terms of resource extraction from the mother, which may lead to impaired development during gestation. Offspring conflict may thus reduce the benefits of polyandry in viviparous species.
