WebThe diversity-resistance hypothesis proposes that high native species richness provides resistance to plant inva-sions, largely on the assumption that more species would more completely occupy niche space (Elton 1958; Levine 8r D'Antonio 1999; Kennedy et al. 2002; Tilman 2004). Empirical tests of the hypothesis have thus far been incon-sistent.

WebOct 29, 2024 · In our study, species richness as the number of native plant species, was the strongest predictor and was positively associated with exotic plant diversity. This is consistent with both facilitation at a large spatial extent (Byers and Noonburg 2003) and with mixed support for the biotic resistance hypothesis (Jeschke et al 2012). Conversely ... WebNov 21, 2024 · Finally, our fifth hypothesis (H5) that resilience and resistance traits would increase while avoidance traits would decrease with time was only partially accepted. For the low salinity levels of up to 5.5 mS cm −1 , resilience and resistance increased while avoidance decreased with time after seawater intrusion. WebAug 24, 2024 · There have been some explanatory hypotheses for how ecological adaptions and mechanistic changes that cause species to succeed, spread, and outbreak in new habitats [ 2, 3, 4 ], such as the diversity resistance hypothesis [ 5 ], empty niche hypothesis [ 6 ], enemy release hypothesis [ 7 ], and symbiotic invasion hypothesis [ … lasten peitto ja tyyny
