Évaluation des effets de l’entaillage de l’érable à sucre sur la production de bois d’oeuvre

The Forestry Chronicle, 2023
La demande croissante des produits confectionnés à partir de la sève d’érable amène à revoir les objectifs de production pour certains peuplements qui étaient jusqu’à présents destinés à une production prioritaire de bois d’oeuvre d’érable à sucre (Acer ...

Variation in Climate Shapes Seedling Recruitment Along Resource Gradients in a Northern Hardwood Forest

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Seedling counts over 26 years revealed that wetter‐site temperate tree species struggle to recruit in warmer, drier years, whereas drier‐site species are more climate‐tolerant. Shadier forests buffered seedlings from heat and drought. Local soils and canopy cover strongly shaped outcomes, revealing considerable differences among species in climate ...

Facile synthesis of water-soluble carbon nano-onions under alkaline conditions

Beilstein Journal of Nanotechnology, 2016
Carbonization of tomatoes at 240 °C using 30% (w/v) NaOH as catalyst produced carbon onions (C-onions), while solely carbon dots (C-dots) were obtained at the same temperature in the absence of the catalyst.

Warming influences nutrient removal in mesocosms across different substrates

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Climate change is increasing stream temperatures globally, likely impacting stream ecosystem processes. We conducted a stream warming experiment at the Notre Dame Experimental Mesocosm Facility using N = 24 recirculating mesocosms to examine the effect of warming on biofilm colonization of organic and inorganic substrata and rates of nutrient ...

Phenolic Glycosides from Sugar Maple (Acer saccharum) Bark

, 2016
Four new phenolic glycosides, saccharumosides A–D (1–4), along with eight known phenolic glycosides, were isolated from the bark of sugar maple (Acer saccharum). The structures of 1–4 were elucidated on the basis of spectroscopic data analysis.

The Biodiversity of Microfungi Isolated from the Bark of the Sugar Maple (Acer saccharum)

, 2022
The Sugar Maple (Acer saccharum) is a keystone species in Eastern North America. Despite this, taxonomic surveys enumerating the fungal populations of the bark of this tree species are lacking.

Variations of the mechanical properties of Acer saccharum roots [PDF]

Journal of Experimental Botany, 1999
Longitudinal and transverse variations in the compressive strength σ c and stiffness measured in bending and torsion (E and G, respectively) were determined for wood samples removed from three old lateral roots of a large sugar maple Acer saccharum L.

Towards weather‐based forecasting of annual seed production in six European forest tree species

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Synthesis and applications: Seed production can be predictable with a promising degree of accuracy for six European tree species in the year prior to seed rain, if combined with on‐site monitoring of seeds, phenology, and weather. This holds value for seed harvesters, nurseries and forest managers, and may inform orchard management and public health ...

Predation on Artificial Caterpillars Varies With Vertical Stratification but Not Light Gradients in a Sugar Maple Temperate Forest

Entomologia Experimentalis et Applicata, Volume 174, Issue 6, Page 559-569, June 2026.
Predation pressure varies vertically, with highest arthropod predation in the understory and highest bird predation in the canopy. Light availability differs across vertical strata, but predation patterns are more strongly influenced by height and forest structure than by light gradients.

Distribution of Eutypella Canker in Sycamore Is Driven by Proximity to Infected Forest Sites, High Precipitation and Moderate Temperatures

Forest Pathology, Volume 56, Issue 3, June 2026.
ABSTRACT Eutypella parasitica, the causal agent of Eutypella canker on maple species, is an invasive forest pathogen recently introduced to Europe. Due to the wide distribution of susceptible Acer species, further spread across European forests is expected.
