Abstract The current and cascading effects of global change challenges the interactions both between animal individuals (i.e. social sexual behaviour) environment they inhabit. Amphibians are an ecologically diverse class with a wide range behaviours, making them compelling model to understand potential adaptations animals faced human-induced rapid environmental changes (HIREC). Poison frogs (Dendrobatoidea) particularly interesting system, as display behaviours that shaped by conspecific interactions, thus offering tractable system investigate how closely related species may respond impacts HIREC. Here, we discuss on poison frog behaviour, future this group face in response such change. We pay special attention parental care territoriality, which emblematic clade, consider different flexibly adapt increasingly frequent anthropogenic stress. More specifically, hypothesise some parents increase clutch attendance distance travelled for tadpole transport) HIREC scenarios more generalist oviposition deposition fare positively than their less flexible counterparts; predict latter either increased competition resources limited or will be forced expand natural preferences. Likewise, human-driven habitat alteration disrupt acoustic visual communication systems due noise pollution and/or surrounding light environment. highlight need empirical research combining behavioural ecology conservation better species’ vulnerability efficiently focus efforts.

Vocalizations are one of the most important communication modalities in amphibian biology, and advertisement call is type vocalization mostly emitted by anurans (frogs toads). In present study, we carried out a scientometric analysis species Colombia to determine state knowledge this science country. We recorded number descriptions its trend throughout more than 60 years; addition, identified how many there with described per taxonomic family, geographic units threat status. According our review, between 1958 June 30 2021, at least 296 studies have been published that describe 307 (of 785 country); only 130 come from recordings individuals Colombian populations. Leptodactylidae Hylidae families highest percentage whose has (84.6% 68.4%, respectively). On contrary, Bufonidae (19.5%) Craugastoridae (12.9%) exhibit low calls.

Despite an increase recent two decades, findings still reveal notable gaps calls anurans, which constitutes incentive develop future research on subject. Finally, based meta-analysis, highlight some recommendations hope stimulate new ecoacoustics, using as study model.

ABSTRACTStudying intraspecific geographic variation in communication signals represents a good approach to understand the evolution of species diversification animals. The poison frog Andinobates bombetes (Dendrobatidae) exhibits spectral traits its advertisement call. However, it is still unknown whether there concomitant temporal call traits, and somehow linked differences warning coloration (red yellow morphs). We analyzed calls recorded from 100 males belonging twelve populations A. bombetes: nine bearing red coloration, three one. After controlling for eventual effects temperature body size we found both yet such was unrelated between populations. Previous research indicated that properties this can be explained by acoustic abiotic environment. Nonetheless, positive relationship distance divergence also supports role genetic drift signaling bombetes.KEYWORDS: Acoustic communicationanuraDendrobatidaegeographic variationpolytypism AcknowledgmentsWe thank Corporación Serraniagua, especially C.
