“…Orienting alongside and parallel to moving conspecifics allows animals to coordinate movement and minimize collisions (Couzin, Krause, James, Ruxton, & Franks, ). Tadpoles of other anuran species, including Anaxyrus woodhousii and Xenopus laevis , have a similar strong preference for being parallel to neighbors (Wassersug et al., ). Our annulus results thus are congruent with other published studies on social aggregations (Hemelrijk & Hildenbrandt, ; Soria, Freon, & Chabanet, ).…”

“…Some tadpole aggregations appear to be based on social attraction, particularly to kin or familiar individuals (Beiswenger, ; Blaustein & Walls, ; Branch, ; Waldman, ; Waldman & Adler, ). However, other tadpole groupings are driven by other cues, such as resource heterogeneity (e.g., Blaustein & Walls, ; Denver, Mirhadi, & Phillips, ; Wells, ) while light is an important cue for the aggregation and orientation of Xenopus larvae (Wassersug et al., ).…”

The role of biotic and abiotic cues in stimulating aggregation by larval cane toads (Rhinella marina)

Tadpoles of the cane toad (Rhinella marina) form dense aggregations in the field, but the proximate cues eliciting this behavior are not well understood. We sampled water‐bodies in the Northern Territory of Australia, finding that the density of cane toad tadpoles increased with increasing temperature. Furthermore, we conducted laboratory experiments to explore the roles of biotic factors (attraction to conspecifics; chemical cues from an injured conspecific; food) and spatially heterogeneous abiotic factors (light levels, water depth, physical structure) to identify the cues that induce tadpole aggregation. Annulus and binary choice trials demonstrated weak but significant attraction between conspecifics. Tadpoles decreased swimming speeds, but did not increase grouping in response to cues from an injured conspecific. Larvae aggregated in response to abiotic cues (high levels of illumination and proximity to physical structures) and were strongly attracted to feeding conspecifics. Overall, aggregation by cane toad tadpoles is likely driven by weak social attraction coupled with a shared preference for specific abiotic features, creating loose aggregations that are then reinforced by movement toward feeding conspecifics.

“…Daphnia and other macro-zooplankton, which, in addition to forming a large component of the diet of small instars, can also be eaten by older instars and adults, move in dense aggregations. Furthermore, the common prey of Ranatra dispar in local habitats-Anisops deanei and other notonectid species, tadpoles and small fish-all move in groups or schools through the water body (see Andorfer 1980;Wassersug 1981;Braden 1982), as well as surface-dwelling species, for example waterstriders, Gerris (see Riley 1921;Spence 1980), and whirligig beetles, Gyrinus (see Heinrich & Vogt 1980). Therefore, Ranatra dispar individuals can be exposed, on occasions, to a group of prey almost simultaneously or over a very short period.…”

‘A prey in the hand’, multi-prey capute behaviour in a sit-and-wait predator,Ranatra dispar (Heteroptera: Nepidae), the Water Stick Insect

The Water Stick Insect, Ranatra dispar, is shown to be able to capture and hold a number of prey simultaneously. Capture of prey characteristically occurs in 3 distinct patterns (Type 1, 2 and 3), each characterized by a different number of prey caught. The time since last feeding by the predator has a significant effect on whether the predator will capture more than one prey. Once feeding starts, there is a critical period during which, if an encounter takes place, the predator will attempt to capture either a second or third prey. The critical period is longer, the higher the motivation level of the predator. It is suggested that this prey-capture behaviour potentially increases the size of a meal as groups of prey move past the stationary predator.

“…This aggregation behavior can exhibit irregular distribution of individuals in constant rotation, or large compact polarized groups usually called "schools" . Schooling behavior may be the result of individual responses to the presence of other tadpoles and / or of other external stimuli (Wassersug Hessler, 1971;Beiswenger, 1975), such as cannibalism or predation (Brattstrom, 1962;Beiswenger, 1977), variations in water temperature (Brattstrom, 1962) and daylight (Brattstrom, 1962;Katz et al, 1981;Wassersug et al, 1981;Branch, 1983).…”

“…Daylight has been shown to trigger aggregative behavior (Beiswenger, 1977;Branch, 1983;Eterovick Sazima, 1999;Surova, 2006) and to influence orientation of tadpoles in ponds (Katz et al, 1981;Wassersug et al, 1981). Low water visibility in ponds caused by diminishing of daylight or by increased water turbidity negatively affects tadpole aggregations, and may even cause dispersal of tadpoles (Beiswenger, 1977;Branch, 1983).…”

The diurnal aggregation behavior in Phasmahyla cochranae tadpoles (Anura: Hylidae)

We investigated schooling behavior of Phasm ahyla cochranae including its periodicity based on periodic regression models. The school structure and differences between day and night were discussed. We found that tadpoles formed aggregative schools, which were significantly more frequent during the day than at night. During the day, from 06:30 to 18:00 h, tadpoles formed one or two polarized schools at the water surface. Based on these results and on observations of specific behaviors, we suggest that daylight may be a significant environmental factor related to schooling behavior in P. cochranae, although this hypothesis needs to be further investigated.
