Abstract We studied the effect of relative parental investment on potential reproductive rates (PRRs) to explain sex differences in selectivity and competition in the dart-poison frog Dendrobates pumilio. We recorded the reproductive behavior of this species in a Costa Rican lowland rainforest for almost 6 months. Females spent more time on parental care than males, and `time out' estimates suggest that PRRs of males are much higher than than those of females, rendering females the limiting sex… 

Population differences in female resource abundance, adult sex ratio, and male mating success in Dendrobates pumilio

The results of this study suggest that ecological variables such as resource availability have a great impact on the mating system and sexual selection through their effect on population structure.

This study resolves an apparent paradox, the negative correlation between mating frequency and reproductive success (=number of produced tadpoles) of individual males in one breeding season.

Territory size as a main driver of male-mating success in an Amazonian nurse frog (Allobates paleovarzensis, Dendrobatoidea)

In polygamous mating systems, it is most often males that compete for the opposite sex, using strategies to provide access to as many females as possible. Females, on the other hand, constitute the

Variation in Male Calling Behaviour and Relation to Male Mating Success in the Strawberry Poison Frog (Dendrobates pumilio)

The data of this study suggest that, in anurans, endurance rivalry contributes more to variation in male mating success than does female choice based on male characteristics.

Spatial distributions of male and female strawberry poison frogs and their relation to female reproductive resources

It is concluded that males did not defend tadpole-rearing sites for females, consistent with the general assumption that female distribution is influenced by resource distribution and that male distribution depends on female distribution.


The findings comply with the notion that female poison frogs prefer to mate with good callers because calling performance is a reliable predictor of offspring quality.

Only distance matters – non-choosy females in a poison frog population

The results suggest that females of O. pumilio prefer the closest calling male in the studied population, and hypothesize that the sampling tactic in this population is affected by a strongly female biased sex ratio and a low variance in traits of available males due to strong male-male competition, preventing low quality males from defending a territory and mating.

Opportunity for Sexual Selection and Effective Population Size in the Lek-Breeding European Treefrog (Hyla arborea).

It is concluded that the lek-breeding system of treefrogs impacts only weakly the patterns of genetic diversity on sex-linked genes and the ability of natural populations to resist genetic drift.


It is demonstrated that a large body size in male L. kuhlii seems to have evolved through intrasexual selection (male-male competition by physical combat) in the context of a resource-defense polygyny mating system.

Mating status correlates with dorsal brightness in some but not all poison frog populations

Overall the results imply that brightness differences among individuals of the same color morph may actually affect reproductive success in some populations of strawberry poison frogs.



Sexual selection and intra-femalecompetition in the green poison-dart frog, Dendrobates auratus

Behavioral, ecological, and molecular genetic analyses of reproductive strategies in the Amazonian dart-poison frog, Dendrobates ventrimaculatus

First field and genetic studies of the reproductive strategies of the Amazonian dart-poison frog Dendrobata vtntrimaculatus suggest that reproductive parasitism may be common in this species.

Sexual selection and the potential reproductive rates of males and females

It is shown that among species where males care for the young, the sex with the higher potential reproductive rate competes more intensely for mates than thesex with the lower potential rate of reproduction.

Potential Reproductive Rates and the Operation of Sexual Selection

This framework for relating sex differences in mating competition to the operational sex ratio, potential reproductive rates, and parental expenditure differs from Triver's concept of the relation between parental investment and mating competition in three ways.

Reproductive phenology and age structure of Dendrobates pumilio in northeastern Costa Rica

To determine seasonality in reproduction and age structure, a sample of 468 individuals was dissected and the conditions of gonads, reproductive tracts, and vocal slits were examined, finding no obvious seasonal trends in patterns of overall abundance.

A technique for deducing the general direction of sexual competition which does not involve direct measurement of operational sex ratio is outlined, and it is stressed that it is important to use the population mean values for relative times out and not the maximum possible value for an individual.

Vocalizations in the Territorial Behavior of the Frog Dendrobates pumilio

The concept of reproductive effort and its relation to the evolution of life histories of lizards is studied and the results show similarities to that of birds and mammals.

Sex differences, sex ratios and sex roles

A new model of mate choice is developed which shows that OSR theory can be used to integrate the effect of sex differences in both mating rate and variation in mate quality to predict the direction ofmate choice.
