Skewed weak and Pareto-tailed strong interactions accompany community diversity and complexity

Koichi Fujimoto, Taiko Arakaki, Takuya Hojo

Ecological communities display a skewed weak and Pareto-tailed strong pattern in interaction strengths that accompanies higher diversity and complexity.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

SWAPS distribution is a previously unrecognized interaction signature of ecological communities and provides a new perspective on the organization of community-level properties.

C2weakest assumption

That taxonomic conservatism of interaction strengths together with multiple interaction types beyond trophic and mutualistic ones are necessary conditions for SWAPS emergence, as demonstrated in the generalized Lotka-Volterra community assembly simulations.

C3one line summary

Empirical plant-animal network data and generalized Lotka-Volterra simulations identify SWAPS interaction distributions as a community signature that requires taxonomic constraints, multiple interaction types, and accompanies elevated diversity and complexity.
