“…The widespread occurrence of these SMGs among dendrobatoids adds a new dimension to studies of the reproductive biology of these frogs, which, for decades, have investigated acoustic, visual, and tactile cues in courtship, mating, and parental care across the diversity of Aromobatidae (e.g., Allobates : Castillo‐Trenn & Coloma, 2008; Costa & Dias, 2019; Juncá, 1998; Lima et al, 2002; Montanarin et al, 2011; Rocha et al, 2018; Roithmair, 1994; Souza et al, 2017; Stückler et al, 2019; Zimmermann, 1989; Anomaloglossus : Bourne et al, 2001; Pettitt et al, 2012; Juncá, 1998; Mannophryne : Dole & Durant, 1974; Greener et al, 2020; Wells, 1980a; Rheobates : Lüddecke, 1999) and Dendrobatidae (e.g., Ameerega : Costa et al, 2006; Forti et al, 2013; Roithmair, 1994; Colostethus : Wells, 1980b; Dendrobates : Rojas & Pašukonis, 2019; Summers, 1992, 2014; Wells, 1978; Epipedobates : Zimmermann, 1989; Hyloxalus : Lötters et al, 2000; Quiguango‐Ubillús & Coloma, 2008; Oophaga : Crump, 1972; Dreher & Pröhl, 2014; Limerick, 1980; Jungfer, 1985; Jungfer et al, 1996; Silverstone, 1973; Summers, 1992; Yang et al, 2019a, 2019b; Paruwrobates : Myers & Burrowes, 1987; Phyllobates : Zimmermann, 1989; Zimmermann & Zimmermann, 1985; Ranitomeya : Caldwell, 1997; Caldwell & Oliveira, 1999) but have almost entirely overlooked the possible role of chemical cues (but see Forester & Wisnieski, 1991; Korbeck & McRoberts, 2005; Schulte, 2016; Schulte & Lötters, 2014; Schulte and Rössler, 2013; Schulte et al, 2011).…”
