Avaliação histórica recuperada de registros do SIGEEI. A estrutura e os campos foram preservados; a confirmação permanece pendente.
Identificação e síntese
Nomenclature and linkage
The original assessment name is preserved. The accepted name and synonyms support discovery and reconciliation without overwriting the historical EICAT record.
Taxonomia registrada
Classificação canônica recuperada da integração com o GBIF. O sistema explicita os níveis que a própria resposta do GBIF não informa.
Avaliação de impactos
1. Redução no desempenho de indivíduos da biota nativa
Resposta: Sim
Evidências por mecanismo
Mussels may modify the nutritional quality of sediments (Mistri, Modugno & Rossi, 2003), have the potential to affect the resident fauna (Crooks, 2001), and render the environment within or under mats unsuitable to adults of other species and/or larval recruitment, through diminishing the depth of the redox potential discontinuity layer, suppressing growth and affecting survival (Morton, 1974; Creese et al., 1997; Crooks, 1998)

2. Declínio no tamanho populacional de espécie nativa
Resposta: Sim
Mecanismos selecionados: (1) Competição,(10) Impacto físico no ecossistema
Evidências por mecanismo
The existence of significantly more macrofaunal invertebrates outside mussel mats may be related to space or food. Because mussels are so dense within the mats, there is little physical space for other species to inhabit and only smaller species or those which are able to readily move through the byssal threads (e.g., errant polychaetes) can live in the habitat created by M. senhousia.

In addition, the anoxic sediment trapped in or under mussel mats may not be a suitable environment for other animals

3. Extinção local de população nativa
Resposta: Não
4. Reversibilidade da extinção local após remoção do táxon
