2024 review
Hosts and impacts of elongate hemlock scale (Hemiptera: Diaspididae): A critical review
[Review of ]. FRONTIERS IN INSECT SCIENCE, 4.
author keywords: invasive alien species; Tsuga; Abies; plant-insect interactions; forest health
TL;DR:
It is confirmed that F. externa is an oligophagous pest of members of Pinaceae, and species of Cupressaceae and Taxaceae have been reported as hosts of F. externa, but they seem unable to support population growth of this pest.

Sesquiterpene Induction by the Balsam Woolly Adelgid (Adelges piceae) in Putatively Resistant Fraser Fir (Abies fraseri)
FORESTS, 13(5).
author keywords: Fraser fir; Abies fraseri; balsam woolly adelgid; Adelges piceae; terpenoids; resistance
TL;DR:
Analysis of artificially infested Fraser fir foliage reveals that increased concentrations of four terpenoid compounds are associated with BWA infestations, and these compounds could serve as effective indicators while screening for BWA resistance in future Christmas tree breeding programs.

Physiological responses of eastern hemlock (Tsuga canadensis) to light, adelgid infestation, and biological control: Implications for hemlock restoration
FOREST ECOLOGY AND MANAGEMENT, 460.
author keywords: Carbohydrate storage; Eastern hemlock; Hemlock woolly adelgid; Invasive species; Integrated pest management; Sunlight
TL;DR:
It is found that trees experienced greater leaf-level stress in gaps and when HWA was actively feeding, and that silvicultural treatments may improve long-term health and survival of infested trees and that integration of such treatments with existing strategies is worthy of continued exploration.

Shade and Hemlock Woolly Adelgid Infestation Increase Eastern Hemlock Foliar Nutrient Concentration
FOREST SCIENCE, 64(6), 577–582.
author keywords: Adelges tsugae; eastern hemlock; foliar nutrient content; invasive species; shade
TL;DR:
The combined effects of prolonged shade with HWA infestation increased foliar [N], [P], and [K], which may be due to reduced growth causing a concentration effect, or nutrients mobilized by the plant in response to infestation.

Population isolation results in unexpectedly high differentiation in Carolina hemlock (Tsuga caroliniana), an imperiled southern Appalachian endemic conifer
Tree Genetics & Genomes, 13(5).
author keywords: Disjunct populations; Gene conservation; Inbreeding; Microsatellite; Population isolation; Rare species
TL;DR:
It is clearly demonstrated that, existing as a limited number of small and isolated populations, Carolina hemlock has insufficient gene flow to avoid widespread genetic drift and inbreeding, despite having the capacity to disperse pollen and seed relatively long distances by wind.

SCANDINAVIAN JOURNAL OF FOREST RESEARCH, 32(5), 397–405.
author keywords: Invasive insects; chemical biology; Fraser fir; Veitch fir; Adelges piceae; Myzus persicae

Elevated light levels reduce hemlock woolly adelgid infestation and improve carbon balance of infested eastern hemlock seedlings
FOREST ECOLOGY AND MANAGEMENT, 385, 150–160.
author keywords: Adelges tsugae; Invasive species; Nonstructural carbohydrates; Shade; Tsuga canadensis
TL;DR:
Although hemlock typically occurs in deeply shaded forests, the results suggest that silvicultural treatments such as forest thinning that increase light exposure may reduce HWA abundance and lead to better tree C balance, and may be an effective component of large-scale conservation and restoration strategies.

Effects of artificial defoliation on growth and biomass accumulation in short-rotation sweetgum (Liquidambar styraciflua) in North Carolina

MeSH headings : Biomass; Forestry; Herbivory; Liquidambar / growth & development; Liquidambar / physiology; North Carolina; Plant Leaves / growth & development; Plant Leaves / physiology; Plant Stems / growth & development; Plant Stems / physiology; Stress, Physiological
TL;DR:
Results indicate that sweetgum is highly resilient to single defoliations of low, moderate, and high intensity, however, during the three-year period of the study, repeated high-intensity defoliation caused significant reductions in growth and productivity that could have lasting impacts on yield throughout a harvest rotation.

Widespread inbreeding and unexpected geographic patterns of genetic variation in eastern hemlock (Tsuga canadensis), an imperiled North American conifer
Conservation Genetics, 13(2), 475–498.
author keywords: Phylogeography; Pleistocene; Migration; Population genetics; Microsatellite; Bottleneck
TL;DR:
Efforts to conserve eastern hemlock genetic material should emphasize the capture of broad adaptability that occurs across the geographic range of the species, as well as genetic variability within regions with the highest allelic richness and heterozygosity, such as the Southern Appalachians and New England, and within disjunct populations that are genetically distinct.
