Schulz A, Havill N, Marsico T, Ayres M, Gandhi K, Herms D, et al.
Ecol Lett . 2025 Feb; 28(2):e70083. PMID: 39967421
Herbivores are commonly classified as host specialists or generalists for various purposes, yet the definitions of these terms, and their intermediates, are often imprecise and ambiguous. We quantified host breadth...

Hofstetter R, Raffa K, Halevy M
J Insect Sci . 2024 Feb; 24(1). PMID: 38417130
The parasitoid wasp, Ooencyrtus kuvanae (Howard) (Hymenoptera: Encyrtidae), is a natural enemy of the spongy moth, a significant forest pest in North America. We investigated the oviposition behavior of O....

Williams G, Ginzel M, Ma Z, Adams D, Campbell F, Lovett G, et al.
Annu Rev Phytopathol . 2023 May; 61:377-401. PMID: 37253697
Society is confronted by interconnected threats to ecological sustainability. Among these is the devastation of forests by destructive non-native pathogens and insects introduced through global trade, leading to the loss...

Uden D, Mech A, Havill N, Schulz A, Ayres M, Herms D, et al.
Ecol Appl . 2022 Oct; 33(2):e2761. PMID: 36218183
Some introduced species cause severe damage, although the majority have little impact. Robust predictions of which species are most likely to cause substantial impacts could focus efforts to mitigate those...

Liu Z, Xing L, Huang W, Liu B, Wan F, Raffa K, et al.
BMC Biol . 2022 Aug; 20(1):190. PMID: 36002826
Background: Biological invasions are responsible for substantial environmental and economic losses. The red turpentine beetle (RTB), Dendroctonus valens LeConte, is an important invasive bark beetle from North America that has...

Howe M, Raffa K, Aukema B, Gratton C, Carroll A
Oecologia . 2022 Feb; 198(3):681-698. PMID: 35226183
Irruptive forest insects such as bark beetles undergo intermittent outbreaks that cause landscape-scale tree mortality. Despite their enormous economic and ecological impacts, we still have only limited understanding of the...

Malmstrom C, Raffa K
Glob Chang Biol . 2022 Jan; 6(S1):35-48. PMID: 35026937
Disturbance regimes strongly determine vegetation patterns and succession in the boreal landscape. One of the current challenges for boreal vegetation modellers is to represent disturbance agents as dynamic factors that...

Erbilgin N, Zanganeh L, Klutsch J, Chen S, Zhao S, Ishangulyyeva G, et al.
Plant Cell Environ . 2021 Oct; 44(12):3636-3651. PMID: 34612515
How carbohydrate reserves in conifers respond to drought and bark beetle attacks are poorly understood. We investigated changes in carbohydrate reserves and carbon-dependent diterpene defences in ponderosa pine trees that...

Howe M, Carroll A, Gratton C, Raffa K
Glob Chang Biol . 2021 Aug; 27(22):5786-5805. PMID: 34428326
Warming temperatures are allowing native insect herbivores to expand into regions that previously exceeded their thermal tolerance, encounter new host species, and pose significant threats to native communities. However, the...

Li Z, Rubert-Nason K, Jamieson M, Raffa K, Lindroth R
J Chem Ecol . 2021 Mar; 47(3):313-321. PMID: 33683546
Climate warming can influence interactions between plants and associated organisms by altering levels of plant secondary metabolites. In contrast to studies of elevated temperature on aboveground phytochemistry, the consequences of...
