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

Sex differences in the repeatability of boldness over metamorphosis
Consistent individual differences in boldness have been identified in many species and can have important effects on fitness. In most animals, juveniles face different costs and benefits ofExpand

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

Parasitism, predation and the evolution of animal personalities.
Trade-offs between behavioural traits promoting high life-history productivity and mortality may fuel the evolution of animal personalities. We propose that parasites, including pathogens, imposeExpand

Integrating behaviour with life history: boldness of the field cricket, Gryllus integer, during ontogeny
Summary 1. According to a recent hypothesis, personality traits should form integrative pace-of-life syndromes with life-history traits. Potential life-history traits that explain personalityExpand

Differing virulence of Aphanomyces astaci isolates and elevated resistance of noble crayfish Astacus astacus against crayfish plague.
Crayfish plague epidemics (caused by Aphanomyces astaci) have been causing population collapses among native European crayfish stocks since the late 1800s. Recent indirect and direct evidence hasExpand

Do pheromones reveal male immunocompetence?
Pheromones function not only as mate attractors, but they may also relay important information to prospective mates. It has been shown that vertebrates can distinguish, via olfactory mechanisms,Expand

Male dominance and immunocompetence in a field cricket
Female preference for dominant males has been found in many species, and it is generally thought that winners of male-male competition are of superior quality. Success in contests probably depends onExpand

A behavioural syndrome in the field cricket Gryllus integer: intrasexual aggression is correlated with activity in a novel environment
Behavioural syndromes, or suites of correlated behaviours across different contexts and situations, have recently drawn attention from evolutionary biologists. In the field cricket Gryllus integer,Expand
