Crocodilians move for many reasons (Lang 1987. In Webb, Manolis and Whitehead [Ed.], Wildlife Management: Crocodiles and Alligators, pp. 273-294. Surrey Beatty & Sons, Chipping Norton, New South Wales). Caiman crocodilus yacare occur in high densities in seasonally flooded habitats in the Brazilian Pantanal (Coutinho and Campo 1996. J. Trop. Ecol. 12:741-747), and food shortages during the dry season have the potential to influence movement. As Santos et al. (1966. Herpetol. J. 6:111-117) mentioned large number adults and tadpoles of Pseudis paradoxa (or soaps) in diet of caiman in the brackish ponds, here I report changes in caimans density potentially linked to changes in soap density in a lake in the Brazilian Pantanal. Observations were made on the Nhumirim Ranch (18 59'S, 56 40'W), Mato Grosso do Sul, Brazil over the period 1989-1999. During night surveys, caiman were counted and soap densities were estimated. One alkaline lake (pH of 9.0-9.9) generally had relatively few (10-34) caiman during each of 20 times it was surveyed. Only two surveys recorded high densities of caiman (>500), but each coincided with high densities of P. paradoxa. In each case, I estimated soap densities on the edge of the lake to be > 100 adults and large tadpoles/m2. On 10 April 1999, we marked 20 caimans of the several hundred present in the lake during the soap eruption. After 150 days, one marked female was recaptured in a river area 5 km away and the total number of caiman we detected in the lake was reduced to 20. These observations suggest that caiman move in response to change in prey density. I thank Sandra Santos and Max Pinheiro for help with surveys in 1989 and Henrique de Jesus, Jose Augusto Silva and Vandir Silva for assistance with capture of caiman.
