The paper quantifies ecosystem degradation by calculating energetic and monetary deficits needed for regeneration, showing nonlinear relationships and significant economic costs in African savannas.

The paper investigates memory effects in ecological systems, showing they enhance stability and short-term recovery but delay full restoration.

The paper shows that food-web architecture determines whether predator advantage supports or undermines collective persistence, with omnivory playing a key role.

This paper develops a geometric framework to show how energetic constraints shape ecological network diversity, revealing a unimodal relationship between energy supply and biodiversity.

The paper develops a method to estimate biodiversity risk metrics from species-area relationships using empirical data from forest censuses.

This paper models how temperature affects species coexistence in pairwise competition, finding that symmetric thermal performance curves maximize coexistence at their intersection temperature.

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 links power, efficiency, and bifurcations in consumer-resource systems using mathematical models and shows how ecological principles can be formalized and tested.

The paper forecasts biodiversity changes in a lake plankton community using abiotic and biotic predictors, showing that temperature and biotic interactions are key for accurate long-term predictions.

The paper derives a general sustainability rule using allometric scaling laws and tests it against ethnographic data from hunter-gatherer societies, finding consistent alignment with predicted sustainability corridors.

The paper shows that ecological systems develop in a sequenced order from fast-to slow-growing taxa due to environmental resistance minimization, supported by theoretical and empirical evidence.
