Letter to the Editor

In a recent publication in the Journal of Chemical Ecology, McGugan et al. (McGugan et al. 2016) analyzed skin alkaloid profiles in the Little Devil poison frog (Oophaga sylvatica, Dendrobatidae) and investigated whether geographic variation in alkaloid profiles correlated with the availability of their arthropod prey (ants and mites). Skin alkaloids of poison frogs are not synthesized de novo by frogs, but are obtained from dietary sources and sequestered to the skin (Saporito et al. 2007, 2011a). These so-called “cleptotoxins” are synthesized by several arthropod groups, of which oribatid mites seem to be a major alkaloid source for poison frogs (Saporito et al. 2007, 2009, 2011b; Takada et al. 2005). Species from most of the major oribatid taxa—including Enarthronota, Mixonomata, Nothrina (Desmonomata s. stricto), and Brachypylina—have been represented in stomach contents of poison frogs (Rodríguez et al. 2010; Saporito et al. 2011b). As we have commented earlier on the paper of...
