Resumen
Una de las mayores poblaciones de cocodrilos de Costa Rica se encuentra en el río Tempisque. La especie está amenazada por la pérdida de hábitat y la cacería, sin embargo, sus poblaciones han crecido debido a la protección otorgada por ley. El estudio se realizó en Guanacaste, Costa Rica. Se hizo una caracterización del conocimiento popular, actividades realizadas y percepciones de 374 residentes de la zona de estudio. Se encontró que el 55% piensa que el cocodrilo es abundante, 70% cree que las poblaciones han aumentado. Las actividades más peligrosas efectuadas son principalmente la recreación, natación y pesca artesanal. Entre ellas se encontraron diferencias significativas entre las proporciones de respuesta (X2: 71, n: 10, p <0.0001). Estas actividades se realizan diariamente (25%), semanalmente (30%), mensualmente (18%), anualmente (10%). No se reconocen los riesgos de ataque ni la densidad de cocodrilos en el río. Así mismo, se muestra una falta de conocimiento acerca la historia natural y ecología de la especie. Las razones de ataque son: la agresividad de los animales y su densidad, encontrándose diferencia entre las respuestas sobre las razones del ataque (X2: 35, n:8 p <0.0001). En general, la percepción de cocodrilo es desfavorable.
One of the largest populations of crocodiles in Costa Rica is located at the Tempisque River. The species is threatened by habitat loss and poaching; but its populations have grown due to the protection given by law. The research was conducted in Guanacaste, Costa Rica. We made a characterization of popular knowledge, activities and perceptions of 374 residents of the study area. It was found that 55% believe that the crocodiles are abundant, 70% believe that populations have increased. The most dangerous activities done are recreation, swimming and fishing. There are significant differences between the proportions of response (X2: 71, n = 10, p <0.0001 X2). These activities are done daily (25%), weekly (30%), monthly (18%) and annually (10%). The risk of attack and the crocodile’s density in the river are not recognized. Also, a lack of knowledge about the natural history and ecology of the species is shown. The reasons for attacks are: the aggressiveness of the animals and their density. There are differences in the responses on the reasons of the attacks (X2: 35, n 8 p <0.0001). Generally, the crocodile perception is unfavorable.
