This study compares structural properties of ecological networks globally, showing degree distribution explains network structure better than connectance, with environmental factors affecting food webs more than other interaction types.

The paper identifies a simple metric, self-regulation loss (SL), that predicts species stability in ecological communities despite their complexity.

The paper shows that emergent coexistence in ecological communities arises from dense networks of indirect effects in species-rich models with pairwise interactions, revealing a limit to reductionist explanations.

This study shows that biotic-abiotic feedbacks can generate nutrient spatial heterogeneity in a plant-herbivore model through varying dispersal, foraging, and recycling behaviors.

This study shows response diversity drives community stability in food webs, with food web structure playing a secondary role.

The paper develops a thermodynamic framework to determine the energetic boundaries of trophic systems and shows how these boundaries limit food-chain length.

The paper introduces a dynamic contribution metric to assess species' functional roles in ecosystems, showing that rare species can be crucial due to biotic interactions.

The paper introduces a Julia package for simulating temporal dynamics of ecological networks with diverse interaction types and environmental drivers.

The paper clarifies that the sublinear growth model does not resolve the species coexistence paradox because it relies on unrealistic assumptions about growth rates at low abundance.

This study identifies three types of multistability in dryland plant communities driven by facilitation and competition under varying stress levels.

The paper estimates the distance to degradation points in dryland ecosystems from images, validated on simulated landscapes and applied to a global dataset to identify fragile sites.

The paper models plant-soil feedbacks and herbivory to show how tannin evolution is driven by soil nitrogen dynamics and mycorrhizal associations in unproductive environments.
