In-depth characterization of intraspecific (self-limitation) mechanisms in the time-varying framework

Characterize in depth the intraspecific interaction mechanisms (self-limitation) within the time-varying generalized Lotka–Volterra (Ricker) framework with environmental covariates used to infer species interactions from abundance time series, focusing on how these self-limiting processes operate and can be parameterized and analyzed alongside interspecific interactions in the studied ecological communities.

Background

The paper develops a time-varying network model based on a generalized Lotka–Volterra (Ricker) formulation with environmental covariates to infer and analyze interspecific interactions across five ecological datasets. While the study quantifies temporal rewiring, stationarity, and structural stability primarily through interspecific links, the authors explicitly note that their analysis focused on interspecific interactions.

They identify an unaddressed component: intraspecific interactions (self-limitation), which in generalized Lotka–Volterra models are typically represented by diagonal terms and play a key role in regulating population dynamics and coexistence. The authors explicitly state that a deeper exploration of these mechanisms is left for future work, making their comprehensive characterization within the presented time-varying framework an open problem.
