An integrated framework to identify and characterize regional‐scale insect dispersal
Abstract Forest pest insects cause major socio‐economic impacts, global losses of millions of dollars, and ecosystem changes. A key challenge for their management is tracing regional dispersal events critical to outbreak dynamics. We developed an integrated tracing framework for pest insects by combining isotope geolocation, ecological data, and ...

DFT calculations and ROESY NMR data for the diastereochemical characterization of cytotoxic tetraterpenoids from the oleoresin of Abies balsamea [PDF]
Eight non-carotenoid tetraterpenoids, abibalsamins C-J (3-10), were isolated from the oleoresin of Abies balsamea. Their chemical structures were determined based on analysis of 1D/2D NMR and MS data.

Abstract Peatlands play a critical role in the global carbon (C)‐climate cycle, acting as vast long‐term stores of disproportionately large quantities of C relative to their land area. In recent decades, climate‐driven shifts in fire regimes and peatland hydrophysical properties have occurred across Canada's boreal regions, increasing concerns about ...

Abibalsamins A and B, Two New Tetraterpenoids from Abies balsamea Oleoresin
Abibalsamins A (1) and B (2), two unprecedented tetraterpenoids featuring a 3,4-seco-rearranged lanostane system fused with a β-myrcene lateral chain via a [4 + 2] Diels–Alder cycloaddition, were isolated from the oleoresin of Abies balsamea.

Abstract Peatlands are known to store significant amounts of carbon (C), nitrogen (N) and phosphorus (P) globally. At the regional level, however, C stocks are often poorly assessed as peat depth variability within and among different types of individual peatlands is often ignored, and nutrient stock assessments are rare or based on limited ...

ABSTRACT Aim Unmitigated climate change will subject species to environments unlike any experienced for millions of years, creating new risks and opportunities for species, especially where niches are truncated and novel climates open previously unavailable portions of the fundamental niche.

Summary Forest health is critical for sustaining ecosystem services like carbon sequestration. Heart rot, a widespread disease in upland northern hardwood forests, may affect greenhouse gas (CO2 and CH4) fluxes, but its impacts remain poorly measured. Using non‐destructive tomography and direct gas flux measurements, we quantified the effects of heart ...
