Plant-animal relationships are manifested through a system of interactions such as: shelter, nesting, pollination, frugivory and occupation of cavities in tree trunks; however, two of them, pollination and frugivory, are the strongest interactions within the mutualistic relationships between plants and animals, since both living organisms involved can coevolve. Therefore, it is essential to investigate and know in detail all the variables involved in these synergistic interactions in order to conserve them and guarantee their continuity over time. In the end, they will determine whether the interacting species prevail or become extinct, which is a crucial element in the conservation of wild flora and fauna. Only in this way will we be able to ensure the survival of these key species for the future.
