Tobin K, Gula S, Couture J, Ginzel M
J Chem Ecol . 2025 Jan; 51(1):1. PMID: 39838224
Thousand cankers disease (TCD) is a pathosystem comprised of Juglandacea spp., a pathogenic fungus Geosmithia morbida, and an insect vector, the walnut twig beetle (WTB) (Pityophthorus juglandis). Of the North...

DeLaMater D, Couture J, Puzey J, Dalgleish H
Am J Bot . 2021 Apr; 108(3):388-401. PMID: 33792047
Premise: Leaf economic spectrum (LES) theory has historically been employed to inform vegetation models of ecosystem processes, but largely neglects intraspecific variation and biotic interactions. We attempt to integrate across...

Williams L, Cavender-Bares J, Townsend P, Couture J, Wang Z, Stefanski A, et al.
Nat Ecol Evol . 2020 Nov; 5(1):46-54. PMID: 33139920
Quantifying how biodiversity affects ecosystem functions through time over large spatial extents is needed for meeting global biodiversity goals yet is infeasible with field-based approaches alone. Imaging spectroscopy is a...

Mason C, Walsh B, Keller J, Couture J, Calvin D, Urban J
Environ Entomol . 2020 Sep; 49(6):1427-1436. PMID: 32960283
Invasive herbivores can have dramatic impacts in new environments by altering landscape composition, displacing natives, and causing plant decline and mortality. One of the most recent invasive insects in the...

Cotrozzi L, Peron R, Tuinstra M, Mickelbart M, Couture J
Plant Physiol . 2020 Sep; 184(3):1363-1377. PMID: 32907885
Advancements in phenotyping techniques capable of rapidly and nondestructively detecting impacts of drought on crops are necessary to meet the 21st-century challenge of food security. Here, we describe the use...

Wang Z, Chlus A, Geygan R, Ye Z, Zheng T, Singh A, et al.
New Phytol . 2020 May; 228(2):494-511. PMID: 32463927
Foliar functional traits are widely used to characterize leaf and canopy properties that drive ecosystem processes and to infer physiological processes in Earth system models. Imaging spectroscopy provides great potential...

Li Z, Yang J, Shang B, Xu Y, Couture J, Yuan X, et al.
Sci Total Environ . 2019 Dec; 707:135935. PMID: 31869612
Tropospheric ozone (O) pollution can alter tree chemical profiles, and in turn, affect forest ecosystem function. However, the magnitude of these effects may be modified by variations in soil water...

Campos-Medina V, Cotrozzi L, Stuart J, Couture J
PLoS One . 2019 Aug; 14(8):e0219431. PMID: 31437174
Insect herbivores can manipulate host plants to inhibit defenses. Insects that induce plant galls are excellent examples of these interactions. The Hessian fly (HF, Mayetiola destructor) is a destructive pest...

Struckman S, Couture J, LaMar M, Dalgleish H
Ecol Lett . 2019 Jun; 22(9):1396-1406. PMID: 31209991
Quantitatively linking individual variation in functional traits to demography is a necessary step to advance our understanding of trait-based ecological processes. We constructed a population model for Asclepias syriaca to...

Cotrozzi L, Couture J, Cavender-Bares J, Kingdon C, Fallon B, Pilz G, et al.
Tree Physiol . 2017 Oct; 37(11):1582-1591. PMID: 29036552
Drought frequency is predicted to increase in future environments. Leaf water potential (ΨLW) is commonly used to evaluate plant water status, but traditional measurements can be logistically difficult and require...
