Wildfire Emissions From European Boreal Fuels: Effects of Fuel Type and Moisture Content
Fire and Materials, EarlyView.ABSTRACT The increasing severity of wildfires poses significant challenges through the release of greenhouse gases and other harmful gases and particles. Although field measurements exist, there is a lack of systematic data collection to understand the influence of moisture content on the particle and gas emissions of boreal fuels, particularly for ...

Journal of Quaternary Science, EarlyView.ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Land Degradation &Development, EarlyView.ABSTRACT The main aim of the study was to assess the toxicity of ash generated in household furnaces through the combustion of materials most commonly burned in individual households. The toxicity tests were conducted using plant bioassays with cress (Lepidium sativum), mustard (Sinapis) and sorghum (Sorghum) seeds.

Genetics and Breeding of Black Spruce and Red Spruce
The Forestry Chronicle, 1969 This review emphasizes findings that are of value for early application in tree breeding and silviculture. Black spruce and red spruce are closely related genetically and hybridize where their ranges overlap, particularly in the Maritime Provinces.

Taxonomic revision of the genus Tzveleviochloa (Poaceae, Aveninae) in India
Nordic Journal of Botany, EarlyView.The taxonomy of Tzveleviochloa in India is revised based on morphological evidence, comprehensive observations of herbarium specimens and field records, and several botanical explorations in the study area. The accepted diversity is increased from two to five species, including two recently described species. The genus is distributed in the Western and

Oikos, EarlyView.Many key ecosystem functions are affected by plant roots and their traits. However, understanding of the patterns in, and drivers of, root traits lags far behind equivalent knowledge of above‐ground tissues, particularly in boreal old growth forests. We surveyed community‐level root traits across 11 old growth forests spanning a wide latitudinal range ...

Reindeer grazing induces spatial and functional shifts in root systems of boreal pine forests
Oikos, EarlyView.The spatial distribution of roots, laterally and vertically, is critical for nutrient and water uptake and for driving root‐associated carbon inputs and turnover. Large herbivores, such as reindeer, influence ecosystems belowground by altering aboveground vegetation composition and soil microclimate.
