Landscape and Geography Determine Saproxylic Beetle Captures in Pheromone‐Baited Traps

Entomologia Experimentalis et Applicata, EarlyView.
Pheromone‐baited traps at 39 forest sites across southern Sweden captured 58 saproxylic beetle species, including seven Red‐listed taxa. The effect of surrounding forest cover on beetle abundance may depend on latitude and longitude: positive effects were strongest in warmer southern and eastern regions but weakened or reversed in colder northwestern ...

The Importance of the Larval Parasitoid Actia interrupta (Diptera: Tachinidae) in Low Density Eastern Spruce Budworm Populations

Entomologia Experimentalis et Applicata, EarlyView.
Actia interrupta is an important larval tachinid parasitoid during low‐density populations of the eastern spruce budworm. In the late 1980s during the outbreak collapse, Meteorus trachynotus was initially the most important species, but was replaced by A. interrupta. Host patch size and density had no impact on the parasitism rates by A.

Assessing Soil-Related Black Spruce and White Spruce Plantation Productivity

Open Journal of Forestry, 2017
This article focuses on modelling and mapping the productivity of black (Picea mariana) and white spruce (Picea glauca) plantations across the Black Brook forest management area in northwestern New Brunswick, Canada, encompassing about 200,000 ha. This effort involved establishing 3500 50 m2 survey plots, each informing about: plantation age (15 to 43 ...

Factors influencing size inequality in peatland black spruce and tamarack: Evidence from post-drainage release growth [PDF]

, 1999
1 We used tree ring analysis to determine stem radius and thus examine size variation over time in two even-aged (approximately 40-year-old) mixed populations of black spruce and tamarack established on peatlands in a boreal forest.
