“…In this context, Engystomops and congeners breed from April to December (Ryan et al 1983), and we captured the males in our study during April. Our data indicated that E. pustulosus consumes arthropods as do most anurans (Parmelee 1999, Narvaez and Ron 2013, Womack and Bell 2020, with the exception of a few species that have been reported to prey on vertebrates such as birds, rodents, and other amphibian species (Santos et al 2004, Caicedo-Martínez et al 2021). This pattern is not surprising because invertebrates are an abundant resource in almost all ecosystems and represent an advantageous food source because of the low energetic costs associated with their capture and consumption (Taigen and Pough 1983, Biavati et al 2004, Vitt and Caldwell 2014, Pacheco et al 2017.…”

We investigated the diet of Engystomops pustulosus from a population in the Middle Magdalena River valley, including an evaluation of theeffect of body and head size on prey number and volume. We present the current state of knowledge of the diet of E. pustulosus from published information in addition to our data. We found a total of 400 prey items representing two phyla, Arthropoda and Mollusca; seven orders and nine families were detected. Arthropods, mainly insects, were the most frequent prey in the diet. Among arthropods, Acari and Isoptera were numerically dominant. We did not observe effects of body and head size on prey number and volume. The published literature of the diet of E. pustulosus included 66 prey items, among which Isoptera (termites), Acari, and Formicidae were the most common groups, suggesting dietary specialization. Prey items consumed by E. pustulosus varied among different localities; Blattodea, Orthoptera, and Thysanoptera were unique at certain localities. Further study of prey availability and diets associated with land-use changes across majorgeographic localities will contribute to a better understanding of the predator-prey interactions in these anthropogenic environments.

“…In the case of a large, aggressive resident (like A. hahneli ), avoidance behaviour might be beneficial, in order to avoid a physical encounter, physical harm or expenditure of energy (Doty, 1986; Lee & Waldman, 2002). Another possibility is that R. sirensis does not recognise the odour of A. hahneli per se, but of anurans in general, perceiving this odour as a potential threat because many larger frogs show anurophagy, including some Neotropical poison frogs (Caicedo‐Martínez et al., 2021; Measey et al., 2015; Santos & Cannatella, 2011). The odour of American bullfrogs ( Lithobates catesbeianus , Ranidae), for example, which regularly prey on smaller amphibians, is recognised and avoided by other ranids (their prey; Murray et al., 2004).…”

Olfaction is the oldest sense in the animal kingdom. It is used during a multitude of behaviours, such as the encounter of food, the detection of predators, the recognition of habitat‐related cues or the communication with conspecifics. While the use of olfaction and chemical communication has been studied widely in some animals, it is barely known in others. Anurans (frogs and toads), for example, are well known to use acoustic and visual senses, but their chemical sense is still largely understudied. Studies concerning the chemical sense in anurans have been mostly based on the use of semiochemicals in juvenile stages, while the information on adult anurans remains limited. In this study, we analysed the behavioural response of the Neotropical poison frog Ranitomeya sirensis (Sira poison frog, Dendrobatidae) when presented with the odours of prey, novel/prey‐luring fruit, habitat, conspecific faeces and heterospecifics. For this, we offered each of the odours by placing them into one of two testing tubes fixed in an arena, with the other tube left empty as a control. We then measured the time the frogs spent in the vicinity of the odour versus the control tube and calculated a response index. While the frogs did not show a significant avoidance or attraction towards most of the tested odours, they showed a strong response towards the heterospecific odour, which was significantly avoided. This is the first evidence of a poison dart frog responding towards the odours of adult heterospecific frogs. We consider potential reasons for this strong negative reaction, such as the interspecific competition avoidance hypothesis, and discuss our results in the context of other animal species being deterred or attracted by heterospecific chemical cues.
