Our examine demonstrates how animals can use robust and predictable environmental cues, such as the lunar cycle, to inform behavioral choices 44 , 45 Finally, we suggest that efforts be increased to study tropical species that present contrasting ecological traits from these in temperate regions, in order that administration and conservation methods within the tropics are informed by the most effective available and relevant data quite than much less applicable temperate zone information.
