Limiting similarity hypothesis
Nettetaccording to phylogenetic limiting similarity, species more closely related in evolutionary time are more ecologically similar and compete more strongly than distant relatives. … Nettet29. mar. 2024 · Using an analytical approach similar to that developed in previous studies (Sugihara et al., 2003; Mouillot et al., 2007; Hidasi-Neto et al., 2024), our results (i.e., negative relationship between SSA and DIFT) are more consistent with the environmental filtering hypothesis than with the limiting similarity hypothesis (which would be …

Nettetplant species. The limiting similarity hypothesis predicts that invasive species are less likely to establish in commu - nities of species holding similar functional traits. Likewise, Darwin s naturalization hypothesis states that invasive spe - cies closely related to the native community would be less successful. NettetLimiting similarity (informally "limsim") is a concept in theoretical ecology and community ecology that proposes the existence of a maximum level of niche overlap between two given species that will allow continued coexistence.. This concept is a corollary of the competitive exclusion principle, which states that, controlling for all else, two species …
Nettet29. jun. 2024 · While the ‘limiting similarity’ hypothesis states that species with more similar traits would compete more strongly and that more dissimilar species are more likely to coexist (MacArthur and Levins 1967), several authors questioned this hypothesis and pointed out the importance of fitness differences (described by ‘trait hierarchy’) rather … Nettet17. jul. 2024 · One key aspect to consider is that the limiting similarity hypothesis assumes that resources are limited, thus leading to biotic filtering through competition …

Given their great morphological similitude and close phylogenetic relationship (i.e., niche retention), these species will have similar ecological requirements and are expected to have strong competitive …

The principle maintains that two species with the same ecological niches cannot … Se mer It is of note that the theory of limiting similarity does not easily generate falsifiable predictions about natural phenomenon. However, many studies have tried to test the theory by making the highly suspect assumption that character displacement can … Se mer As proposed by MacArthur and Levins in 1967, the theory of limiting similarity is rooted in the Lotka–Volterra competition model. This model describes two or more populations with logistic dynamics, adding in an additional term to account for their biological interactions. … Se mer The key weakness of the theory of limiting similarity is that it is highly system specific and thus difficult to test in practice.
