Climate stresses and monetary resources seem to lead to different collective adaptations. However, the reference to adaptation and to ambiguous collective dimensions appears premature; populations may entertain nothing more than shared adaptiveness. At this point, the intricacy of the underlying evolutionary processes (cultural selection, fitness-utility decoupling) very much obscures any ...

Vocally trained actresses are expected to have more vocal economy than nonactresses. Therefore, we hypothesize that there will be differences in the electroglottogram-based voice economy parameter quasi-output cost ratio (QOCR) between actresses and nonactresses. This difference should remain across different levels of intensity. A total of 30 actresses and 30 ...

Superparasitism in solitary parasitoids results in fatal competition between the immature parasitoids, and consequently only one individual can emerge. In the semisolitary ovicidal parasitoid Echthrodelphax fairchildii (Hymenoptera: Dryinidae), two adults can emerge under superparasitism with a short interval (<24 h) between the first and second ovipositions. We determined the female ...

Because birds' acoustic signals function in antagonistic interactions between males and in female attraction, a majority of vocalisations are loud. In contrast, some birds, additionally produce soft vocalisations in escalated agonistic and sexual contexts. Nevertheless, the relationship between the acoustic parameters of such signals and their function is not clear. ...
