The cost of male aggression and polygyny in California sea lions (Zalophus californianus).
PLoS ONE, 2010 In polygynous mating systems, males often increase their fecundity via aggressive defense of mates and/or resources necessary for successful mating. Here we show that both male and female reproductive behavior during the breeding season (June-August ...

Fecundity, an overlooked life-history trait for coastal management of commercial molluscs?
Frontiers in Marine Science, 2023 Gonadal development in limpets is well-known. However, the integration of fecundity data on coastal management actions remains overlooked. Here, we use fecundity of two exploited limpets (Patella ordinaria and P. aspera) to demonstrate its potential as a

Heterozygote Advantage for Fecundity
PLoS ONE, 2006 Heterozygote advantage, or overdominance, remains a popular and persuasive explanation for the maintenance of genetic variation in natural populations in the face of selection. However, despite being first proposed more than 80 years ago, there remain few examples that fit the criteria for heterozygote advantage, all of which are associated with ...

Reproductive inequalities in the acanthocephalan Corynosoma cetaceum: looking beyond "crowding" effects [PDF]
, 2018 Background: At present, much research effort has been devoted to investigate overall (average) responses of parasite populations to specific factors, e.g., density-dependence in fecundity or mortality. However, studies on parasite populations usually pay

"A Method for the Estimation of Fecundability." [PDF]
Studies in Family Planning, 1975 AbstractA new method for the estimation of the mean and variance of fecundability is described. The data input required for this procedure is the distribution of the interval from marriage to first birth, or from the resumption of the conception risk after contraception to the subsequent birth.
