MO · Moderado
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
Mecanismos selecionados: (1) Competição,(12) Impactos indiretos via interações com outras espécies
Evidências por mecanismo
\"Agrostis capillaris, Bromus tectorum, Cirsium arvense and marginally significantly also Lupinus polyphyllus all suppressed the other species richness more in the invaded rather than native ranges. (...) For all species native to Europe and invasive in North America (Agrostis capillaris, Bromus tectorum and Cirsium arvense), the richness of native species in the invaded range decreased with increasing cover of the dominant (Table 2 and Fig. 1)\" (Hejda et al. 2017)
\"We found significantly higher pollinator visitation rate to resident species in plots where C. arvense was absent compared to when it was present (Table 2A; Fig. 2)\" (Daniels and Arceo-Gómez 2020)
