title: Mexilhões do entre-marés como engenheiros ecossistêmicos: manutenção de comunidades de invertebrados em meio a gradientes de estresse
abstract: Species that form complex biogenic structures may increase niche space for many others and are assumed to be paramount for whole-assemblage stability and ecosystem functioning.Because they often ameliorate physical conditions, ecosystem engineering species are also predicted to become more important with environmental stress.Testing this hypothesis, however, has proven difficult because isolating facilitation effects along the entire stress gradient is challenging.Here we addressed motile invert
