Insufficient Chilling Effects Vary among Boreal Tree Species and Chilling Duration
Frontiers in Plant Science, 2017 Insufficient chilling resulting from rising winter temperatures associated with climate warming has been an area of particular interest in boreal and temperate regions where a period of cool temperatures in fall and winter is required to break plant ...

Spruce budworm feeding and oviposition are stimulated by monoterpenes in white spruce epicuticular waxes [PDF]
Insect Science, 2016 AbstractMonoterpenes, source of the distinctive odor of conifers, are generally considered plant defensive compounds. However, they are also known to act as long‐range insect attractants, as they are volatile and permeate forest airspaces. Moreover, they are lipid soluble and can be absorbed into plant epicuticular waxes.

Applications in Plant Sciences, EarlyView.Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

White spruce limestone ecotypes
The Forestry Chronicle, 1974 White spruce provenances from soils with limestone parent material, and non-limestone parent material were planted on calcareous and non-calcareous soils. The limestone provenances grew the most on calcareous soils: the non-limestone provenances grew the most on non-calcareous soils. Limestone ecotypes have evolved by natural selection.

Carbon Energy, EarlyView.ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Carbon Energy, EarlyView.ABSTRACT Hard carbon (HC) is currently the predominant anode material for sodium‐ion batteries; however, its practical application is still limited by insufficient initial Coulombic efficiency (ICE) and plateau capacity. Meanwhile, conventional HC production relies on energy‐intensive carbonization processes with considerable carbon emissions. Here, an

Frontiers in Forests and Global Change, 2021 Drought stress associated with warm temperatures is causing increased mortality and reduced growth of trees in drier portions of the boreal forests of western Canada with both warming and drought expected to increase over the coming decades.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope
