Realizamos un estudio comparativo de los patrones de actividad del jaguar y el puma dentro de un mosaico de áreas protegidas (AMR) y en un rancho ganadero (CR) en Pantanal, Brasil, para comprender mejor sus patrones de actividad en estos paisajes. Presumimos que los patrones de actividad del jaguar y el puma estarían sesgados al período nocturno en la ganadería, pero no en las áreas protegidas. Utilizamos datos de cámaras trampa analizados a través de un enfoque de densidad kernel no paramétrico para explorar las relaciones temporales interespecíficas e intraespecíficas entre estas especies en ambos sitios. Obtuvimos 71 registros independientes de jaguar y 29 de puma en AMR, y 85 registros independientes de jaguar y 26 de puma en CR. Los patrones de actividad de jaguares y pumas
difirieron entre sitios, siendo ambos catemerales en AMR, pero nocturnos en CR con superposiciones de moderadas a altas, de acuerdo con nuestra hipótesis. En general, nuestros datos sugieren que la ganadería no es incompatible con la existencia de jaguares y pumas, sino que moldea su patrón de actividades.
