Singing to impress: the importance of developmental stress
Notice bibliographique
Résumé
It was the aim of our review (Spencer and MacDougall-Shackleton, this issue) not only to describe the evidence in favor of the developmental stress hypothesis (DSH) but also to place this hypothesis in what we believe to be an appropriate wider context of the evolution of other indicators of developmental stability. We are heartened by the many comments that agree with us with respect to our attempt to widen the influence of this hypothesis and drive future work. We also agree that it is becoming more evident from a large body of work that it is important to take developmental conditions into account when measuring the effects of environmental changes on adult performance, a difficult task when studying natural populations. Although there is a large body of empirical evidence in favor of the DSH, we highlight that there are several questions that still remain unanswered. Studies to date have merely focused on the long-term effects of developmental stress on song signal quality, and we currently do not know the relative importance of genes and environment in shaping signal quality during development (Buchanan et al. 2004). Kvarnemo (this issue) suggests that we assert it does not matter whether the resultant sexual signal is representative of “good genes” and an ability to cope well with stress or a lack of stress during development. In contrast, we feel that this is an important issue, merely one that is hard to disentangle empirically and that has received little attention in the past. It is hard to imagine a natural environment without any stressors at all, but developmental environments will differ in their “stressfulness” through a variety of different routes, such as parental provisioning or anthropogenic disturbance. Individuals are thus almost certain to vary in the level of stressors they experience and in their ability to cope with them. It thus remains unclear, in the developmental stress framework, whether song signals the indirect benefits of developmental stability, the potential direct benefits derived from a benign developmental history, or both. There has been a great debate within the realms of sexual selection research concerning the relative importance of both direct and indirect benefits in driving the evolution of exaggerated secondary sexual traits, and this is bound to continue. We are enthusiastic about the possibility of researchers in different areas taking up this challenge to further our knowledge of the interaction between genes and the environment in maintaining sexual signals and agree wholeheartedly that this is an area that requires further work (Kasumovic, this issue; Swaddle, this issue; Kvarnemo, this issue).

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
