Biennial aerial application of Bacillus thuringiensis Berliner var. kurstaki is the most cost-effective approach of protection against spruce budworm (Choristoneura fumiferana [Clemens])

Annals of Forest Science
Key message Aerial application of Bacillus thuringiensis Berliner var. kurstaki (Btk) every second year to stands of white spruce (Picea glauca (Moench)Voss.), black spruce (Picea mariana Mill.) and balsam fir (Abies balsamea (L.) Mill.) is the most cost-

Short‐term soil responses and site conditions to inverted mounding on peatland linear features in Alberta, Canada

Restoration Ecology, EarlyView.
Abstract Introduction Seismic lines represent one of the most extensive and persistent anthropogenic disturbances in boreal peatlands, limiting forest regeneration and altering key ecosystem functions. Inverted mounding is increasingly applied to elevate planting microsites above shallow water tables, yet evidence on short‐ to medium‐term biophysical ...

TOLERANCE OF WHITE SPRUCE SEEDLINGS TO FLOODING

The Forestry Chronicle, 1964
One and two-year-old white spruce seedlings growing in trays in the laboratory were immersed in water for periods of 3½, 7, 10½, and 14 days. Total mortality resulted from the 14-day immersion period, but a small percentage of seedlings survived the shorter periods and even repeated immersions for 3½-day periods.

Tree‐Ring Oxygen Isotope Values During the Last Glacial Maximum and Insights to Future Changes in Climate

Terra Nova, EarlyView.
ABSTRACT Annual tree‐ring oxygen‐isotope values were measured from sections of two fossil logs of Picea mariana (black spruce) recovered from last glacial maximum proglacial sediment in Illinois, USA. Collectively, the specimens date from ca. 25,130 to 24,720 cal years BP.

Nutritional and reproductive dynamics of moose near their southern range limit

The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
Though southern moose (Alces alces) had relatively low seasonal fluctuations in body fat, their condition was positively associated with pregnancy and adult survival but did not influence recruitment of young. We demonstrated clear signs of nutritional limitation and unexpected patterns of reproductive performance that may be unique to moose living at ...

Bridging data gaps: Evidence‐based population assessment for an endemic amphibian of conservation concern

The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
Plethodon welleri exhibits strong seasonal shifts in elevational activity with abundance and occupancy being linked to terrain characteristics. Despite historical habitat assumptions, P. welleri occurs in a broad range of forest types across a larger elevation gradient. Photo Credit to Maxwell Ramey.
