Immunocompetence, developmental stability and wingspot size in the damselfly Calopteryx splendens L.
Calopteryx splendens males exhibit a remarkable variation in wing pigmentation both within and between populations. In this study, we examined whether the wingspots of male C.splendens are related toExpand

Courtship song and immune function in the field cricket Gryllus bimaculatus
It has been assumed that sexual ornaments have evolved to reveal males’ health and vigour for females. Choosy females may indirectly use ornaments as an indicator of the presence and effectiveness ofExpand

Condition dependence of pheromones and immune function in the grain beetle Tenebrio molitor
Summary 1. Pheromones are chemical signals that function not only as mate attractors, but may also relay important information to prospective mates. In order for the information to be reliable, theExpand

Effect of bacterial infection on antioxidant activity and lipid peroxidation in the midgut of Galleria mellonella L. larvae (Lepidoptera, Pyralidae).
Bacillus thuringiensis is one of the most widely used sources of biorational pesticides, as well as a key source of genes for transgenic expression to provide pest resistance in plants. In this studyExpand

The role of juvenile hormone in immune function and pheromone production trade-offs: a test of the immunocompetence handicap principle
The immunocompetence handicap hypothesis postulates that secondary sexual traits are honest signals of mate quality because the hormones (e.g. testosterone) needed to develop secondary sexual traitsExpand

Interspecific aggression and character displacement in the damselfly Calopteryx splendens
Problems in species recognition are thought to affect the evolution of secondary sexual characters mainly through avoidance of maladaptive hybridization. Another, but much less studied avenue for theExpand

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 theExpand

Evidence for the stress-linked immunocompetence handicap hypothesis in humans
Secondary sexual traits that develop under the action of testosterone, such as masculine human male facial characteristics, have been proposed to signal the strength of the immune system due to theExpand

Attractiveness of women's body odors over the menstrual cycle: the role of oral contraceptives and receiver sex
It is a long held assumption that women have concealed ovulation, which means that men do not know when women's menstrual cycles are in their most fertile phase. Recent empirical results haveExpand

There is more than one way to skin a G matrix
Because of its importance in directing evolutionary trajectories, there has been considerable interest in comparing variation among genetic variance–covariance (G) matrices. Numerous statisticalExpand
