DOI: 10.1002/ajpa.23360
Abstract: OBJECTIVES The phrase "level of sperm competition" is used only vaguely in the primate literature. There is also little distinction between the important elements of frequency and intensity of sperm competition, largely because the two… read more here.

Multiple paternity and the number of offspring: A model reveals two major groups of species
Sign Up to like & getrecommendations! Published in 2021 at "BioEssays"
DOI: 10.1002/bies.202000247
Abstract: Parentage analyses via microsatellite markers have revealed multiple paternity within the broods of polytocous species of mammals, reptiles, amphibians, fishes and invertebrates. The widespread phenomenon of multiple paternity may have attending relationships with such evolutionary… read more here.

DOI: 10.1002/ece3.71749
Abstract: ABSTRACT In social mammals, dominance status and tenure length are often important determinants of male reproductive success. Nevertheless, alternative strategies, such as extra‐pair mating, and the active role of females in securing reproductive benefits can… read more here.

DOI: 10.1002/ece3.72230
Abstract: ABSTRACT Highly polymorphic markers like microsatellites are extensively utilized in genomic studies to analyze and infer genealogical relationships among individuals in a population. Traditional methods to identify the most likely parent among the potential known… read more here.

DOI: 10.1007/s00595-024-02959-y
Abstract: Work–life balance is often discussed in Japan. Yet surgeons find it challenging to take paternity leave because of their demanding surgical duties and a strong sense of responsibility. One Japanese male surgeon had his first… read more here.

DOI: 10.1007/s12526-017-0713-4
Abstract: The black rockfish (Sebastes schlegelii) has a viviparous reproductive pattern and long-term sperm storage. Multiple paternity is frequently reported in this species. Six polymorphic microsatellite markers were applied to genotype 23 pregnant females (11 wild… read more here.

Territoriality ensures paternity in a solitary carnivore mammal
Sign Up to like & getrecommendations! Published in 2017 at "Scientific Reports"
DOI: 10.1038/s41598-017-04820-4
Abstract: In solitary carnivorous mammals, territoriality is assumed to benefit male fitness by ensuring the exclusivity of matings within territories via mate guarding and female defence. However, this hypothesis remains empirically untested. Here, we examined this… read more here.
