Immunocompetence, developmental stability and wingspot size in the damselfly Calopteryx splendens L.
TLDR
The results suggest that the size of wingspot is an indicator of male quality in C.splendens, and the nylon implant encapsulation rate was positively correlated with the density of haemocytes in the haemolymph.
Courtship song and immune function in the field cricket Gryllus bimaculatus
TLDR
It seems possible that by preferring males according to their courtship song, females might benefit by increasing the parasite resistance of their offspring by choosing males with high immunocompetence.
The role of juvenile hormone in immune function and pheromone production trade-offs: a test of the immunocompetence handicap principle
TLDR
The results reflect a general mechanism by which the immunocompetence handicap hypothesis may work in insects and suggest that JH, which is involved in the control of reproduction and morphogenesis, also plays a central role in the regulation of a trade–off between the immune system and sexual advertisement in insects.
Evidence for the stress-linked immunocompetence handicap hypothesis in humans
TLDR
Positive relationships between testosterone, facial attractiveness and immune function (antibody response to a hepatitis B vaccine) in human males are shown and some preliminary evidence that these relationships are moderated by naturally co-occurring cortisol is presented.
Condition dependence of pheromones and immune function in the grain beetle Tenebrio molitor
TLDR
The results show that pheromones are condition-dependent signals, the quantity of which females use in their mate choice, and the production of the phersomones is affected by the condition of the male.
Attractiveness of women's body odors over the menstrual cycle: the role of oral contraceptives and receiver sex
TLDR
The results indicate that men can use olfactory cues to distinguish between ovulating and nonovulating women, and the contrasting results between pill users and nonusers may indicate that oral contraceptives demolish the cyclic attractiveness of odors.
Foliar Phenolics are Differently Associated with Epirrita autumnata Growth and Immunocompetence
The quality of available food may affect insect herbivores directly (via growth and survivorship) and/or indirectly (by modifying insect vulnerability to parasitoids and pathogens). We examined the
An analysis of trade‐offs in immune function, body size and development time in the Mediterranean Field Cricket, Gryllus bimaculatus
TLDR
The results indicate that there is no single trait that can be termed ‘immunocompetence’ and that an understanding of trade-offs between the different types of immune function and life-history traits will require a more detailed analysis of the physiological basis of the traits.
Parasite stress and pathogen avoidance relate to distinct dimensions of political ideology across 30 nations
TLDR
It is found that national parasite stress and individual disgust sensitivity relate more strongly to adherence to traditional norms than they relate to support for barriers between social groups, which suggests that the relationship between pathogens and politics reflects intragroup motivations more than intergroup motivations.
