Consistent male-male paternity differences across female genotypes.
In a recent paper, we demonstrated that male-female genetic relatedness determines male probability of paternity in experimental sperm competition in the Peron's tree frog (Litoria peronii), with a more closely related male outcompeting his rival. Here, we test the hypothesis that a male-male difference in siring success with one female significantly predicts the corresponding difference in sir...
متن کاملFemale reproductive synchrony predicts skewed paternity across primates
Recent studies have uncovered remarkable variation in paternity within primate groups. To date, however, we lack a general understanding of the factors that drive variation in paternity skew among primate groups and across species. Our study focused on hypotheses from reproductive skew theory involving limited control and the use of paternity "concessions" by investigating how paternity covarie...
متن کاملConsistent neuroanatomical age-related volume differences across multiple samples.
Magnetic resonance imaging (MRI) is the principal method for studying structural age-related brain changes in vivo. However, previous research has yielded inconsistent results, precluding understanding of structural changes of the aging brain. This inconsistency is due to methodological differences and/or different aging patterns across samples. To overcome these problems, we tested age effects...
متن کاملA self-consistent approach to paternity and parental effort.
We review the relationship between optimal parental effort and paternity, and emphasize the need for a self-consistent approach. A fundamental consistency condition is what we refer to as the conservation of paternity. Every offspring has exactly one father. If a male has a paternity of less than unity, then another male or other males must have gained the lost paternity. Our approach also emph...
متن کاملSexual Selection in the Water Spider: Female Choice and MaleMale Competition
When selection acts differently on the body size of males and females, their adult sizes may diverge. The resulting sexual size dimorphism (SSD) covers an astounding range across taxa, with extreme examples in both directions (see Fairbairn et al. 2007). Generally, in most sexually reproducing animals, females are the larger sex (Andersson 1994; Fairbairn et al. 2007), which is mainly explained...
