Phytochemicals as mediators for host range expansion of a native invasive forest insect herbivore

N Erbilgin - New Phytologist, 2019 - Wiley Online Library
Mountain pine beetle (MPB) has recently invaded jack pine forests in western Canada. This
invasion signifies a climate change‐induced range expansion by a native insect. The …

Conifer-killing bark beetles locate fungal symbionts by detecting volatile fungal metabolites of host tree resin monoterpenes

D Kandasamy, R Zaman, Y Nakamura, T Zhao… - PLoS …, 2023 - journals.plos.org
Outbreaks of the Eurasian spruce bark beetle (Ips typographus) have decimated millions of

Mechanisms of systemic resistance to pathogen infection in plants and their potential application in forestry

SK Wilson, T Pretorius, S Naidoo - BMC Plant Biology, 2023 - Springer
Background The complex systemic responses of tree species to fight pathogen infection
necessitate attention due to the potential for yield protection in forestry. Results In this paper …

Fortifying the forest: thinning and burning increase resistance to a bark beetle outbreak and promote forest resilience

SM Hood, S Baker, A Sala - Ecological Applications, 2016 - Wiley Online Library
Fire frequency in low‐elevation coniferous forests in western North America has greatly
declined since the late 1800s. In many areas, this has increased tree density and the …

Drought-mediated changes in tree physiological processes weaken tree defenses to bark beetle attack

T Kolb, K Keefover-Ring, SJ Burr, R Hofstetter… - Journal of chemical …, 2019 - Springer
Interactions between water stress and induced defenses and their role in tree mortality due
to bark beetles are poorly understood. We performed a factorial experiment on 48 mature …

Defence syndromes in lodgepole–whitebark pine ecosystems relate to degree of historical exposure to mountain pine beetles

KF Raffa, CJ Mason, P Bonello, S Cook… - Plant, Cell & …, 2017 - Wiley Online Library
Warming climate is allowing tree‐killing bark beetles to expand their ranges and access
naïve and semi‐naïve conifers. Conifers respond to attack using complex mixtures of …

Hotter droughts alter resource allocation to chemical defenses in piñon pine

AM Trowbridge, HD Adams, A Collins, LT Dickman… - Oecologia, 2021 - Springer
Heat and drought affect plant chemical defenses and thereby plant susceptibility to pests
and pathogens. Monoterpenes are of particular importance for conifers as they play critical …

Local carbon reserves are insufficient for phloem terpene induction during drought in Pinus edulis in response to bark beetle‐associated fungi

RA Thompson, SC Malone, D Peltier, D Six… - New …, 2024 - Wiley Online Library
Stomatal closure during drought inhibits carbon uptake and may reduce a tree's defensive
capacity. Limited carbon availability during drought may increase a tree's mortality risk …

Combined drought and bark beetle attacks deplete non‐structural carbohydrates and promote death of mature pine trees

N Erbilgin, L Zanganeh, JG Klutsch… - Plant, Cell & …, 2021 - Wiley Online Library
How carbohydrate reserves in conifers respond to drought and bark beetle attacks are
poorly understood. We investigated changes in carbohydrate reserves and carbon …

Colonization behaviors of mountain pine beetle on novel hosts: Implications for range expansion into northeastern North America

DW Rosenberger, RC Venette, MP Maddox… - PLoS …, 2017 - journals.plos.org
As climates change, thermal limits may no longer constrain some native herbivores within
their historical ranges. The mountain pine beetle, Dendroctonus ponderosae Hopkins, is a …
