“…In contrast to our data, the diet of P. oxyrhynchus from a forest-savannah ecotone in central Ivory Coast was less diverse and mainly consisted of spiders and orthopterans [21]. These differences might be due to differing prey availability and/or other environmental conditions [37,38].…”

“…This difference between maximal oxygen supply and the metabolic cost of basic physiological maintenance (aerobic scope) allows an organism to devote energy to additional functions, such as locomotion and reproduction (Carey, 1979). Temperature is a well‐documented environmental cue that affects anuran calling activity (see review in Duellman & Trueb, 1986). High levels of humidity and rainfall decrease the risk of desiccation during breeding activity, since anurans have highly permeable skin (Blaustein, Wake, & Sousa, 1994).…”

Understanding the temporal dynamics of communities is crucial to predict how communities respond to climate change. Several factors can promote variation in phenology among species, including tracking of seasonal resources, adaptive responses to other species, demographic stochasticity, and physiological constraints. The activities of ectothermic vertebrates are sensitive to climatic variations due to the effect of temperature and humidity on species physiology. However, most studies on temporal dynamics have analyzed multi‐year data and do not have resolution to discriminate within‐year patterns that can determine community assembly cycles. Here, we tested the temporal stability and synchrony of calling activity and also how climatic variables influence anuran species composition throughout the year in a metacommunity in the Atlantic Forest of southern Brazil. Using a multivariate method, we described how the relationship between species composition and climatic variables changes through time. The metacommunity showed a weak synchronous spatial pattern, meaning that species responded independently to environmental variation. Interestingly, species composition exhibited a nonstationary response to climate, suggesting that climate affects species composition differently depending on the season. The species‐climate relationship was stronger during the spring, summer, and winter, mainly influenced by temperature, rainfall, and humidity. Thus, temporal community dynamics seem to be mediated by species life‐history traits, in which independent fluctuations promote community stability in temporally varying environments.

“…The authors described the call as territorial, and suggested a distress call function, because they were emitted while the individual were being held by the researcher (Vilaça et al 2011). Contrastingly, distress calls are characterized by loud, explosive calls emitted in response to disturbance or potential predators (Duellman and Trueb 1986), thus all the characteristics described in Vilaça et al (2011) lead us to conclude that they presented the species release call. Release calls are emitted by males when they are inappropriately clasped by males, or by females when they are unreceptive, which affirms this type of call as a signal for sex recognition (Wells 2007;Liao and Lu 2009).…”

“…The release call is a signal produced by the frog when it is inappropriately clasped by another frog (Duellman and Trueb 1986;Wells 2007;Gollmann et al 2009;Toledo et al 2014). There are also males that emit release calls during physically aggressive interactions (Bastos and Haddad 1995;Brunetti et al 2015).…”

Anurans emit a variety of acoustic signals in different behavioral contexts during the breeding season. The release call is a signal produced by the frog when it is inappropriately clasped by another frog. In the family Phyllomedusidae, this call type is known only for Pithecophus ayeaye. Here we describe the release call of four species: Phyllomedusa bahiana, P. sauvagii, Pithecopus rohdei, and P. nordestinus, based on recordings in the field. The release calls of these four species consist of a multipulsed note. Smaller species of the Pithecopus genus (P. ayeaye, P. rohdei and P. nordestinus), presented shorter release calls (0.022-0.070 s), with higher dominant frequency on average (1508( .8-1651, when compared to the bigger Phyllomedusa (P. bahiana and P. sauvagii) (0.062-0.107 s; 798.7-1071.4 Hz). For phyllomedusid species, the release call might indicate a phylogenetic signal, because species of the same genus have similar acoustic traits.
