Sexual Selection and the Barn Swallow
Models of sexual selection and monogamy the study organism male mating advantages benefits of mate choice determinants of tail ornament size advantages of early arrival options for unmated malesExpand
Sperm competition in birds : evolutionary causes and consequences
Birds as vehicles for sperm competition avian mating systems and sperm competition male and female reproductive systems and the fertile period sperm precedence and mechanisms of sperm competitionExpand
Why have birds got multiple sexual ornaments?
Three hypotheses are examined that may account for the presence of multiple ornaments in males of many animals, including the multiple message hypothesis, the redundant signal hypothesis, and the unreliable signal hypothesis. Expand
Sperm Competition in Fishes: The Evolution of Testis Size and Ejaculate Characteristics
It is found that both the gonadosomatic index and sperm numbers increase with intensity of sperm competition across species but that sperm length decreases, which does not fit predictions of current sperm competition theory. Expand
Sperm competition and sexual selection
This chapter discusses Sperm Competition in Birds, Sexual Selection in Spiders and Other Arachnids, and Reproduction, Mating Strategies and Sperm competition in Marsupials and Monotremes. Expand
Stressed mothers lay eggs with high corticosterone levels which produce low-quality offspring.
Maternal stress impaired offspring phenotype and viability by increasing transmission of glucocorticosteroids to the eggs, and a novel mechanism mediating early maternal effects whereby maternal stress affects offspring quality is identified. Expand

A review of available information from the literature on the relationship between developmental instability and various fitness components such as growth, fecundity, and longevity suggests that there indeed is a general negative relationship. Expand
A resolution of the lek paradox
It is shown that additive genetic variation is also higher in sexual traits, and often greater than in the same, non-sexually selected trait in females or other comparable traits in thesame species, contrary to the expectations of the lek paradox. Expand
Assessing the impact of climate variation on survival in vertebrate populations
Analysis of long‐term monitoring data at the individual scale is often the only available approach to estimate reliably demographic parameters of vertebrate populations, and statistical procedures used in these analyses are reviewed. Expand
