Equilibrium and disequilibrium biodiversity dynamics: understanding biodiversity responses to environmental changes

GA ČR 25-18055S

Understanding the causes of biodiversity variation on Earth is crucial, especially given the rapid environmental changes we face today. Consensus exists that biodiversity is primarily limited by energy availability, suggesting, e.g., that current biodiversity loss is inevitable due to human appropriation of ecosystem production. However, significant gaps persist in understanding the temporal dynamics of the diversity-energy relationship. Central to this understanding is determining when biodiversity is in equilibrium and the factors driving the equilibrium /disequilibrium dynamics.

We aim to investigate these processes using the novel framework of Equilibrium Theory of Biodiversity Dynamics. We will examine states of biodiversity equilibria and disequilibria through systematic analysis across scales and taxa, focusing on underexplored moderate to small time scales. By integrating empirical data with theory and simulation models, we aim to elucidate how changes in energy availability influence biodiversity patterns, offering new insights for effective conservation strategies.
