    Las interacciones entre los depredadores y sus presas en el mundo real son afectadas usualmente por diversos fenómenos ecológicos actuando tanto en las presas como en los depredadores.

    La colaboración o cooperación entre los depredadores es una de esas conductas, la cual ha recibido menor atención de los investigadores que la competición entre los consumidores. Estas conductas influyen de manera importante en las dinámicas de las cadenas alimenticias o redes tróficas.

    En este trabajo, estudiaremos la influencia de la colaboración o cooperación (hunting cooperation) entre los depredadores para consumir (o capturar) a sus presas favoritas, las cuales son afectadas por un efecto Allee débil.

    The interactions between predators and their prey in the real world are usually affected by diverse ecological phenomena acting on both the prey and the predators.

    Collaboration or cooperation between predators is one of those behaviors, which has received less attention from researchers than competition among consumers. These contacts are important aspects of the dynamics of food chains and trophic webs.

    In this work, we will study the influence of collaboration or cooperation (hunting cooperation) between predators to consume (or capture) their favorite prey, which are affected by an effect Allee weak.

    We extend the results obtained in a previously published model, considering only collaboration between predators and in which the Allee effect is absent.
