Tree Physiological, Physical, and Chemical Characteristics Related to Spruce Beetle Colonization: Engelmann versus Blue Spruce

Creator:

Ott, Daniel S.

Abstract:

Blue spruce (Picea pungens) and Engelmann spruce (Picea engelmannii) experience varying levels of spruce beetle (Dendroctonus rufipennis (Kirby)) colonization, yet the underlying differences and mechanisms resulting in lower colonization for blue spruce are not known. Both spruce species have important roles in subalpine ecosystems where examining changes in mortality, distribution,...

Interactions Between Wild Bee Communities and Douglas-fir Beetle (Dendroctonus pseudotsugae) Populations in Douglas-fir (Pseudotsugae menziezii) Forests of the Intermountain West

Creator:

Foote, Gabriel G.

Abstract:

This work combines both applied and basic research regarding previously undescribed relationships between two ecologically and economically important insect groups in coniferous forests, bark beetles (Coleoptera: Curculionidae, Scolytinae) and wild bee (Hymenoptera: Apiformes) communities in Western North America. Across the continent, native bark beetle outbreaks are key drivers of structural...
