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/ece3.4628
Abstract: Abstract Whether the ovarian fluid (OF) represents a selective environment influencing cryptic female choice was tested using an external fertilizer experiencing intense sperm competition and large effects of OF on sperm swimming behavior—the Arctic charr… read more here.

DOI: 10.1007/s00383-019-04598-8
Abstract: Objective To determine the effect of tobacco consumption on paternity rates in men with a history of cryptorchidism. To compare the paternity rates between formerly unilateral, bilateral cryptorchid smokers, and nonsmokers. Methods A retrospective cohort… 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.

DOI: 10.1016/j.jflm.2018.02.003
Abstract: National and international reports regarding the paternity testing activity scarcely include information from Mexico and other Latin American countries. Therefore, we report different results from the analysis of 3005 paternity cases analyzed during a period… read more here.

DOI: 10.1016/j.jpurol.2019.10.008
Abstract: INTRODUCTION Spermatic cord torsion (SCT) may lead to organ loss and can potentially influence fertility. Long-term effects of SCT are not fully investigated. OBJECTIVE The purpose was to evaluate paternity rates in adults who have… 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.

DOI: 10.1071/zo18006
Abstract: Abstract. Genetic mating systems described for squamate reptiles range from primarily monogamous to completely polygynandrous. The presence of female multiple mating is almost ubiquitous among squamates and even occurs, albeit at a low rate, in… read more here.
