Resumen

Ecological interactions such as those involving arthropod predators and parasitoids and their prey or hosts provide evidence for selective pressures influencing small vertebrate populations, and are key to understanding the many connections that shape food webs in tropical rainforests. Here, we document 15 predator-prey interactions involving different types of arthropod predators and vertebrate prey including frogs, lizards, snakes, and a mammal. Documented also are three cases of fly myiasis in frogs, and provide further evidence of a commensal relationship involving a tarantula and a narrow-mouthed frog in lowland Amazonian Peru.
