Calls, colours, shape, and genes: a multi-trait approach to the study of geographic variation in the Amazonian frog Allobates femoralis

Abstract: Evolutionary divergence in behavioural traits related to mating may represent the initial stage of speciation. Direct selective forces are usually invoked to explain divergence in mate-recognition traits, often neglecting a role for neutral processes or concomitant differentiation in ecological traits. We adopted a multi-trait approach to obtain a deeper understanding of the mechanisms behind allopatric divergence in the Amazonian frog, Allobates femoralis. We tested the null hypothesis that geographic distanc… Show more

“…For example, A. femoralis has become a model organism for behavioral and communication research in this century. The existence of different call morphotypes has been pivotal to experiments investigating inter-population acoustic recognition [50], natural hybridization [32], acoustic signal evolution [28,51], and the information carried by distinct components of these signals [52]. The premature loss of one of these call morphotypes will undoubtedly leave an irreversible knowledge-gap that will affect many burgeoning research lines.…”

“…The characterization of A. femoralis advertisement calls recorded near Altamira adds to previous work that sampled the species' repertoire. It might influence future reappraisals of the species' biogeography (Amézquita et al, 2009) and sound signal evolution and its correlates (Santos et al, 2014), for which comprehensive data on intraspecific variation are desirable. Importantly, the recognition of the new, six-note call arrangement in the field led to concomitant DNA barcoding that associated this call morphotype to unique and distinct mitochondrial DNA haplotypes (Simões et al, 2014).The description presented in this study can therefore be used in the forthcoming years in monitoring programs to confirm whether the distribution of this lineage is restricted to forest remnants in or near sites impacted by the Belo Monte dam, on the Xingu River (Simões et al, 2014).…”

“…In this location, A. femoralis males emit calls formed by six notes, a pattern distinct from that of the typical, and geographically prevailing advertisement calls, formed by four notes (Amézquita et al, 2009;Simões et al, 2014). The evolutionary implications of call variation in A. femoralis from Altamira are vastly unknown, but no sharing of mitochondrial DNA haplotypes is detected between this group and other A. femoralis distributed in locations adjacent to the geographic boundaries of the Altamira region (Simões et al, 2014).…”
