Mating Systems and Strategies

This book presents the first unified conceptual and statistical framework for understanding the evolution of reproductive strategies and offers a method for quantifying how the strength of sexual selection is affected by the ecological and life history processes that influence females' spatial and temporal clustering and reproductive schedules.

Reproduction in Reef Fishes

Criteria for the Diagnosis of Hermaphroditism in Fishes

The strongest indicators of protandry are transitional individuals whose gonads contain degenerating testicular tissue and developing ovarian tissue, and experimental production of transitional or sex-reversed individuals through manipulation of the social system may identify both protogyny and prot andry.

Associations between body size, mating pattern, testis size and sperm lengths across butterflies

The results suggest that sperm competition in butterflies selects for increased investment in spermatogenesis, and specifically longer fertilizing sperm, which are not selected to be minimally sized to maximize numbers for a purely raffle-based sperm competition mode.


It is argued that a much broader understanding of the “relative importance” of multiple causal processes will be gained by striving to understand how the contribution of each process is modified by other processes than by attempting to quantify the "importance" of eachprocess.

Size‐dependent resource allocation and sex allocation in herbaceous perennial plants

It is found that if female fitness gain is a linear function of resource investment, then a fixed amount of resources should be allocated to male function, and to post‐breeding survival as well, for individuals above a certain size threshold.

Variable Pelagic Fertilization Success: Implications for Mate Choice and Spatial Patterns of Mating

Fertilization success was measured in the bluehead wrasse, Thalassoma bifasciatum, a tropical reef fish with external fertilization of pelagic eggs, and data suggest that females may gain fertilizations by selecting partic- ular locations or periods of calmer water conditions to spawn.

Sex Allocation in Hermaphroditic Sea Basses

A broader view of local mate competition that includes aspects of sperm competition and the dynamics of fertilization should ultimately provide more accurate predictions of sex allocation in hermaphroditic organisms.
