Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Abstract BACKGROUND Downy mildew, caused by Pseudoperonospora cubensis, is one of the most destructive diseases affecting cucumber and remains difficult to manage sustainably through fungicide‐dependent control strategies. Although several resistance loci have been reported, many previously mapped regions remain too broad for efficient marker‐assisted ...

Understanding how species interactions relate to biodiversity requires linking complex interaction networks to coexistence mechanisms. In diverse communities, interactions span trophic levels and include pairwise and higher‐order effects, yet their relative importance for explaining population dynamics remains poorly understood.
