Data from: Experimental inhibition of a key cellular antioxidant affects vocal communication
1.There is substantial interest of evolutionary ecologists in the proximate mechanisms that modulate vocal communication. In recent times, there has been growing interest in the role of oxidative stress as a mediator of avian song expression. 2.Here we tested whether the experimental inhibition of the synthesis of a key cellular antioxidant (glutathione) reduces song rate metrics of male European starlings (Sturnus vulgaris). We measured the effect of our treatment on total song rate and on its two components, undirected and nest-box oriented song, outside the breeding season. 3.Treated males that did not own a nest-box (subordinate males likely to be of lower quality) suffered increased oxidative stress relative to untreated males, while treated males that owned a nest-box (dominant males likely to be of higher quality) did not. Treated non-owners also reduced their undirected song rate, whereas treated nest-box owners did not suffer any reduction in song rate. 4.Our results revealed that inhibition of a key cellular antioxidant results in decreased vocal communication in a social vertebrate, and that this effect is dependent on its social status (nest-box owner versus non-owner). 5.This work provides support for the hypothesis that acoustic signals may honestly convey information about the individual oxidative status and capacity to regulate the oxidative balance. Our findings raise the possibility of hitherto unexplored impacts of oxidative stress on fitness traits in social species.
The impact of parasitic infection on acoustic communication and mate choice in two torrent frogs with nonlinear vocalization
<p><span>For frogs with linear vocalization, Hamilton and Zuk's hypothesis indicated that parasites adversely affect male sex characters and </span><span>parasite infection can result in sexual signals that are less intense or conspicuous than in healthy individuals, which causes females to prefer unparasitized over parasitized males. </span><span>In order to investigate the effects of parasite infection on vocal characteristics and mate choice in frogs, which can emit nonlinear phenomena calls (NLP). The calls of the two species of torrent male frog, namely the concave-eared torrent frog </span><span>(<em>Odorrana</em> <em>tormota</em>)</span><span> and the large odorous frog </span><span>(<em>Odorrana</em> <em>graminea</em>), </span><span>were recorded, and several vocal parameters (calling duration, calling rate, average fundamental frequency, NLP duration and NLP content) and parasite intensity were analyzed in detail. The results revealed a negative relationship between calling rate and parasite intensity and a positive relationship between NLP content and parasite intensity. Furthermore, the effects of parasite intensity on amplectant showed that parasite intensity from amplexed pairs was higher than that of solo males in the vicinity of the amplexus. This might be because both male frogs with higher parasite intensity can emit calls with higher NLP content, and it has been shown that females have a preference for high NLP content. </span><span>This study confirms that parasites can influence the NLP content in both torrent frog' calls, which in turn affects the host' mate choice. The current study suggests effects of parasite infection on mate choice in host frogs might be influenced by vocal manner, which provides new insight into the parasite-host relationship.</span></p>
