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
Evidências por mecanismo
“For plants grown in the large columns, wild oat plant weight decreased with increasing numbers of yellow starthistle plants, but the differences were not significant for either 2005 (ANOVA, P 5 0.20, Figure 3) or 2006 (ANOVA, P 5 0.86). (…) When the number of yellow starthistle increased, wild oat final height decreased. Wild oat started to senesce shortly after reaching final height.”

2. Declínio no tamanho populacional de espécie nativa
Resposta: Sim

\"Yellow starthistle infestations may reduce wildlife habitat and forage, displace native plants, and decrese native plant and animal diversity (Sheley and Larson 1994). Dense infestations also threaten natural ecosystems and nature reserves by fragmenting sensitive plant and animal habitat (Scott and Pratini)\" (DiTomaso et al. 2006) \"Yellow starthistle can occur in dense monocultures (fig. 8) (see Stand Structure) that displace native plants; decrease native plant and animal diversity; reduce native wildlife habitat and forage; and alter water cycles, soil microbial community composition, and soil nutrient availability [17,25,62,64,139,264].\" (Innes 2021)
