The evolution and maintenance of elaborate secondary sexual characters in males have been the subject of intense interest since Darwin's time. [...] Key Method We examined whether individuals with larger horns were less likely to be infected with parasites, and had lower parasite loads and stronger immune systems. In males, horn size was significantly negatively correlated with the number of different parasites infecting an individual (parasite richness), the likelihood of infection with strongyle nematodes and…Expand

Condition- and parasite-dependent expression of a male-like trait in a female bird
TLDR
Examining the effects of season, age, condition, and parasites on the size of supra-orbital combs displayed by female red grouse Lagopus lagopus scoticus provides a better understanding of proximate mechanisms behind the expression of a male-like trait in females and discusses its possible function as a female ornament.
Nematode–coccidia parasite co-infections in African buffalo: Epidemiology and associations with host condition and pregnancy
TLDR
The results suggest that demographic and seasonal variation may mediate the effects of parasites, and their interactions, on the distribution and fitness costs of infection.
Sex, War, and Disease: The Role of Parasite Infection on Weapon Development and Mating Success in a Horned Beetle (Gnatocerus cornutus)
TLDR
The sum of morphological, competition, and immunological data indicate that during a life history stage where no new resources are acquired, males allocate their finite resources in a way that increases future mating potential.
Patterns of parasitism in the cooperatively breeding meerkat: a cost of dominance for females
TLDR
Compared with subordinates, dominant meerkats may experience increased exposure to directly transmitted parasites, and the increased susceptibility of dominant females may reflect energy allocation for preferentially maintaining dominance and breeding status over parasite defense.
Caution on the assessment of intestinal parasitic load in studying parasite-mediated sexual selection: the case of Blackbirds coccidiosis.
TLDR
Data on oocyst output of Isosporaturdi in the faeces of blackbirds (Turdus merula) is presented to illustrate the importance of developing methods that are relevant for a particular model system, instead of relying on existing methods that may work in other systems.
Parasite insight: assessing fitness costs, infection risks and foraging benefits relating to gastrointestinal nematodes in wild mammalian herbivores
TLDR
Three elements of parasitism from the host's perspective are reviewed: fitness costs of infection, risks of infection during foraging and benefits of nutritious pasture, and the trade-off between infection risk and nutritional benefit generated by avoidance of contaminated patches.
A Novel Test of the Immunocompetence Handicap Hypothesis
The immunocompetence handicap hypothesis (ICHH) provides an explanation for the display of honest secondary sex characters as influenced by androgen levels, the immune system and its response, and…
Within guild co-infections influence parasite community membership: a longitudinal study in African Buffalo.
TLDR
Within guild co-infections were the strongest predictors of haemoparasite infections in the buffalo; but that seasonal and host characteristics also had important effects, suggesting a role for interactions among parasites infecting a single tissue type in determining infection patterns.
Both candidate gene and neutral genetic diversity correlate with parasite resistance in female Mediterranean mouflon
TLDR
This study suggests that factors likely to impact genetic diversity and allelic frequencies, including global changes, are also expected to impact parasite resistance, and in particular suggests that different parasite classes are impacted by different genetic drivers.
Behavioral Effects of Parasitism in Animals
Abstract Parasites are found in and on all living organisms. The ways in which a parasite manipulates the behavior of the host to its own advantage are wide ranging and are summarized in this…

TLDR
Data supported by an alternate route Hamilton & Zuk’s hypothesis on parasite-driven sexual selection that conspicuous male plumages of birds could be reliable signals of parasite resistance in a passerine bird.
Parasitism, Host Immune Function, and Sexual Selection
TLDR
The multivariate analyses demonstrating strong effect sizes of immune function in relation to the expression of secondary sexual characters, and for species with male parental care as compared to those without, suggest that parasite resistance may be a general determinant of parasite-mediated sexual selection.
Testosterone, immunocompetence, and honest sexual signaling in male red grouse
TLDR
It is suggested that comb size honestly indicates immunocompetence and males' ability to cope with certain parasites and females could thus benefit from choosing mates based on the expression of this sexual trait.
INTRASPECIFIC VARIATION IN PLUMAGE COLORATION REFLECTS IMMUNE-RESPONSE IN GREAT TIT (PARUS-MAJOR) MALES
TLDR
The view that brighter males signal low parasitation intensity as a result of their superior immunity is favoured, as it is well known that the number and proportions of different types of leucocytes reflect the health status of individuals, as these cells quickly respond to stress and infectious diseases.
Sexual ornamentation relates to immune function in male red grouse Lagopus lagopus scoticus
TLDR
The findings suggest that comb size relates to immune function rather than T. tenuis parasite infection intensity, and males with bigger combs are likely to be of higher phenotypic quality because they are more immunocompetent and might be better able to cope with the detrimental effects of parasites.
Secondary sexual characters and female quality in primates
TLDR
Results imply that sexual swelling size does not indicate female quality in a semifree-ranging colony of mandrills, and that males do not allocate mating effort as a function of swelling size.
Antlers honestly advertise sperm production and quality
TLDR
Red deer antlers could signal male fertility to females, the ability to avoid sperm depletion throughout the reproductive season and/or the competitive ability of ejaculates, and a global measure of relative antler size and complexity is associated with relative testes size and sperm velocity.
Female plumage spottiness signals parasite resistance in the barn owl (Tyto alba)
TLDR
This study is the first one showing that a heritable secondary sexual characteristics displayed by females reflects parasite resistance, and suggests that the ability to resist parasites covaries with the extent of female plumage spottiness.
Female choice for parasite-free male satin bowerbirds and the evolution of bright male plumage
TLDR
Data did not show the predicted relationship between parasite numbers with plumage quality that is needed to support the bright male hypothesis, nor did it show the inverse correlation between male condition and parasite numbers that is predicted by both the brightmale and correlated infection hypotheses.

Abstract A new model for the evolution of horns in female bovids postulates that females mimic male secondary sexual characters to buffer their male offspring against the aggression of dominant…
