Ecological stoichiometry of mountain pine beetle, its mutualist fungi, and the disease white pine blister rust in whitebark pine By Diana Six, Hannah Alverson and Lorinda Bullington Research Gate October 22, 2025 Category: Forestry Ecological stoichiometry can help clarify how symbionts and other co-occurring organisms mediate nutrient deficiencies for hosts.

I. INTRODUCTION Bark beetles are natural disturbance agents that drive the structure and function of conifer forests worldwide. However, in the Anthropocene they are causing unprecedented tree mortality (Hlásny, Zimová & Bentz, 2021). Despite their importance, we lack a comprehensive understanding of bark beetles in a broader community ecology context. Here, we focus on ‘true’ tree-killing bark beetles and their symbiotic fungal partners that can cause outbreaks in their native habitat.

By Dominick A. DellaSala, David Lindenmayer and Diana Six, The Revelator Over the past few years, many decisionmakers and forest managers have increasingly called for “active management” of natural forests — human intervention via mechanical thinning and other forms of commercial logging and road building — in response to increasing wildfires, beetle outbreaks and intense storms. Many activists oppose these methods, saying they do more harm than good.
