Large male mating advantage in natterjack toads, Bufo calamita: sexual selection or energetic constraints?
Article Abstract:
The effect of male body size on mating success was studied in natterjack toads during two breeeding seasons with different temporal patterns of reproductive activity. Results show that larger males mate more than smaller males. The female sexual preference can not be explained by size-related acoustic variables. However, longer chorus attendance is correlated well with male mating success. Small males may not be able to visit the breeding sites more often due to energy limitations since toads do not feed during the breeding period.

Lateralized agonistic responses and hindlimb use in toads
Article Abstract:
Research was conducted to examine the hypothesis that visual lateralization and motor preferences exist in toad species as in higher vertebrates. Lateralized visual behavior was observed in the South American cane toads, Bufo marinus, which displayed a tendency to strike with their tongue at toads they see in their left visual field. Three species of toad also exhibited hindlimb preferences for contact righting. Results provide strong evidence that behavioral lateralization in toads is not limited to handedness.

In search of water: orientation behaviour of dehydrated natterjack toads, Bufo calamita
Article Abstract:
Research describing the ability of natterjack toads to find water is presented. In an experimental environment the toads show wide discrepancies in water finding ability and rely on a multisensory orientation system.
