Avaliação de impactos
1. Redução no desempenho de indivíduos da biota nativa
Resposta: Não
2. Declínio no tamanho populacional de espécie nativa
Resposta: Sim
Mecanismos selecionados: (2) Predação
Evidências por mecanismo
\"Domestic dogs have contributed to 11 vertebrate extinctions (Table 1) and are a known or potential threat to 188 threatened species worldwide. This includes 96 mammal (33 families), 78 bird (25 families), 22 reptile (10 families), and three amphibian (three families) species (Fig. 1a; Table A1). Of these threatened species, 30 are classed as Critically Endangered (two of which are classed ‘possibly extinct’), 71 Endangered, and 87 Vulnerable (Table A1). Predation is the most frequently reported impact, followed by disturbance, disease transmission, competition, and hybridisation (Fig. 1b).\" (Revisão de Doherty et al. 2017).
