Energetic constraints shape the diversity of feasible ecological networks

Chengyi Long, Marco Tulio Angulo, C. Brandon Ogbunugafor…·Serguei Saavedra

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

On the energetic boundaries of trophic systems

Serguei Saavedra, Chengyi Long, Sonia Kéfi…·Marco Tulio Angulo

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

Linking power, efficiency, and bifurcations in consumer-resource systems

Serguei Saavedra, Yuguang Yang, Christopher P. Kempes…·Marco Tulio Angulo

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