Tab. 1 in Is coexistence between non-native and native Erythrinidae species mediated by niche differentiation or environmental filtering? A case study in the upper Paraná River floodplain

Tab. 1. Main definitions and assertions of each theory, highlighting differences between them. Limiting similarityNiche filteringNiches of species overlap less than expected by chance (Fowler et al., 2014).Species niches overlap more than expected by chance (Fowler et al., 2014).Closely related taxa compete most strongly (MacArthur, Levins, 1967).Habitat characteristics can be viewed as filters imposed on species gene pools to select traits suited to a particular set of environmental conditions (Díaz et al., 1998). The coexistence of many species Large differences among species within a community can be due may actually more often result to weak interspecific interactions in exclusion than in coexistence (Kokkoris et al., 2002). (Herben et al., 2014) Occurs at only small spatial scales Occurs at any spatial scale (Takahashi, Tanaka, 2016). (Takahashi, Tanaka, 2016). Differences among species allow Similarities among species allow the persistence (Hutchinson the persistence (Mouillot et al., 1959; MacArthur, Levins, 1967; 2005; Mouchet et al., 2010). MacArthur, 1970).
