“…However, the significance of such behavior may be unrelated to mating. Several studies showed that anurans use celestial light as a cue for orientation (Ferguson et al, 1967;Ferguson et al, 1968;Landreth and Christensen, 1971). It is possible that our experimental design revealed a similar effect and females used the light for some form of orientation unrelated to the localization of specific mates.…”

The visual ecology of nocturnal anurans is poorly understood, but there is growing evidence that vision plays a role in important behaviors such as mate choice. While several recent studies have demonstrated that females are responsive to visual cues when selecting mates, the forces responsible for these preferences are unknown. We investigated the responsiveness of female gray treefrogs, Hyla versicolor, to video playbacks of calling conspecific males in which we varied attributes of the vocal sac, a conspicuous visual characteristic of calling males and a target of female choice in other species. Females responded surprisingly strongly to the video playbacks, but did so indiscriminately with respect to variation in vocal sac characteristics. We followed up on these results with a series of additional tests that examined female responses to abstract stimuli. Females continued to respond to such stimuli, leading us to conclude that their behavior was related to a generalized phototactic response. Because of this, we were unable to make conclusions regarding female preferences for vocal sac characteristics. Nonetheless, our results are significant in two respects. First, we illustrate that despite much effort into improving video playback methodologies, challenges remain, and we offer our experimental design as a method to ensure that appropriate conclusions can be drawn from such studies. Second, we argue that the female phototactic response has potentially significant behavioral implications and in general the consequences of anuran visual preferences deserve further investigation.

“…Greenberg, 1976). Spatial orientation and navigation are common, complex features of amphibian and reptilian recognition behavior (see, e.g., Oe Rosa & Taylor, 1982;Ferguson, Landreth, & McKeown, 1967;Landreth & Ferguson, 1968;Murphy, 1981). Althoughsuchphenomena are quite likely dependent on the operation of mechanisms similar to releaser-induced recognition, their complexity currently defies analysis and will not 00 further discussed.…”

This review evaluates the bases of the widely held assumption that amphibians and reptiles possess impoverished learning abilities. ProceduraHy defined forms of learning (instrumental conditioning, Pavlovian conditioning and autoshaping, imprinting, and social learning) are reviewed, as weH as evidence for the involvement of learning in various behavioral phenomena, including aversive stimulus and predator avoidance, noxious and palatable food recognition, conditioned aversion formation, search image, conspecific recognition, habitat recognition, and cultural transmission of stimulus recognition. The evidence reviewed suggests that amphibian and reptilian learning, for the most part, consists of a releasing-stimulus-induced redirection of innately organized released responses. Amphibians and reptiles appear to learn what stimulus to respond to rather than how to respond to a particular stimulus.

SUMMARYWe introduce the normalized spatial median as an estimator of location for rotationally symmetric distributions on the hypersphere. We investigate some of its asymptotic properties and use them to obtain confidence regions for the modal direction of a distribution on the hypersphere. These results are then applied to the von Mises-Fisher distribution and to a contamination model. It is seen that the normalized spatial median can perform more efficiently than the normalized mean in presence of outliers.
