But despite the long period necessary to return to stability they continue to persist as systems since their parts do not change.

Resumo: Abstract According to classic ecology, resource partitioning by segregation along at least one of the three main niche axes (time, food, and space) must take place for the coexistence of species with similar ecological requirements. We used nocturnal light traps to investigate the assemblage ...

Indirect commensalism promotes persistence of secondary
... Competition between prey species can lead to an indirect mutualism between their consumers1,3,4 because a predator that reduces the density of its prey also reduces competition at the prey's trophic level, positively affecting other prey species and their respective consumers.. The 2012 study by D. ...
