Oikos, Volume 2025, Issue 12, December 2025.Self‐organised pattern formation creates heterogeneous growth conditions in spatially extended ecosystems and can support local functional diversity in metacommunities – sets of communities linked by dispersal. However, the mechanisms connecting emergent heterogeneity on the metacommunity scale and diversity on the local scale, and how they depend on ...

Advanced Theory and Simulations, Volume 8, Issue 9, September 2025.This study evaluates the simulation capabilities of lithium‐ion battery (LIB) electrochemical simulation software packages. The benchmark simulation results reveal the impacts of parameter sensitivity to solver performance and stability. The guidelines to troubleshooting common solver failures at high current rates lowers the steep learning curve to ...
