“…Video and animation techniques represent an increasingly popular and frequently used tool to investigate principles of sexual selection (Mehlis, Bakker, & Frommen, ), aggression (McGinley & Taylor, ), visual communication (e.g. species and kin recognition: Macedonia et al., ; Van Dyk & Evans, ), anti‐predator responses and boldness (Fischer et al., ), social perception (Watanabe & Troje, ) and shoaling preferences (Nakayasu & Watanabe, ). Such techniques include the use of photographs, videos, 2‐D animations, 3‐D animations and 3‐D models (reviewed in Baldauf, Kullmann, & Bakker, ; Woo & Rieucau, ) and have been used to investigate intra‐ and interspecific behavioural responses in taxonomically‐diverse taxa, including birds (Moravec, Striedter, & Burley, ), mammals (Campbell, Carter, Proctor, Eisenberg, & de Waal, ), reptiles (Macedonia et al., ), arachnids (Uetz, Clark, Roberts, & Rector, ) and fishes (Mazzi, Künzler, & Bakker, ).…”

Virtual stimuli represent an increasingly popular tool in the study of animal behaviour. Modern techniques have the potential to simplify and improve traditional experiments using live stimuli. However, the increasing availability of diverse techniques is associated with problems and limitations. Although many new methods have been developed, their validation remains largely untested. In the present study, we therefore performed two experiments to test whether 2‐D animations of predators and conspecifics elicit biologically appropriate behavioural responses in male rainbow kribs, Pelvicachromis pulcher. Individual responses towards a sympatric natural fish predator, Parachanna obscura, were tested using live predators and still colour photographs, animated using PowerPoint©. Compared to control trials (empty aquarium and white computer screen, respectively), individuals decreased their activity in response to both live and animated predators. We found no difference in activity between live and animation trials. Further, we tested individual aggression (frequency of aggressive behaviours) exhibited towards live and animated conspecifics. Individual aggressive behaviours shown towards live and animated conspecifics were positively correlated. Moreover, an individual's mean distance towards the opponent was a suitable proxy for individual aggression permitting the facilitation and standardisation of an individual's aggression through the use of a tracking software compared with the more laborious, traditional manual assessment. Our results show that simple, inexpensive animation techniques have the potential to provide an easy‐to‐apply and useful technological advance in animal behaviour research.

“…Microhabitat motion (Ord et al, 2007;Ord & Stamps, 2008), predation (Leal & Rodriguez-Robles, 1997), and species recognition (Ord & Martins, 2006;Macedonia et al, 2015) are all important drivers that shape anole display behavior and which might be impacted by interspecific competition. For instance, the commonly observed perch use divergence resulting from interspecific competition in Anolis lizards (Williams, 1972(Williams, , 1983Stuart et al, 2014;Dufour, Herrel & Losos, 2017) might induce new microhabitat pressures in terms of predation, light or motion background environment.…”

Invasive species are a global threat to biodiversity. Cases where the invasion has been tracked since its beginning are rare, however, such that the first interactions between invasive and native species remain poorly understood. Communication behavior is an integral part of species identity and is subject to selection. Consequently, resource-use and direct interference competition between native and invasive species may drive its evolution. Here, we tested the role of interactions between the recently-introduced invasive lizard Anolis cristatellus and the native Anolis oculatus on variation in behavior and communication in Calibishie (Dominica). From May-June 2016, we filmed 122 adult males of both species displaying in banana farms under two contexts (allopatry and sympatry). We then recorded i) the proportion of time spent displaying and ii) the relative frequency of dewlap versus push-up displays. To control for habitat variation, we measured and compared the habitat characteristics (canopy cover and habitat openness) of 228 males in allopatry and sympatry. While the habitat characteristics and total display time did not differ between the contexts for the two species, the proportion of display-time spent dewlapping by A. cristatellus decreased in sympatry. The display of A. oculatus did not differ between the contexts, however. Shifts in microhabitat use, predation pressure, or interspecific interference are potential factors which might explain the behavioral changes in display observed in A. cristatellus. This study highlights the role of behavioral traits as a first response of an invasive species to recent competition with a closely-related native species.PeerJ reviewing PDF |
