Abstract The southern pine beetle (SPB) (Dendroctonus frontalis Zimmermann) is the most economically important pest of southern pine forests. Beetles carry fungal cells within specialised cuticular structures, called mycangia. Little is known about the mycangia...

Fuel dynamics and its implication to fire behavior in loblolly pine dominated stands after southern pine beetle outbreak
Abstract Southern pine beetle (SPB) (Dendroctonus frontalis Zimm) outbreaks and wildfire occurrence in recent decades has triggered growing concerns regarding their possible interactions. However, few studies have quantified the fuel characteristics of SPB-killed...
Spatio-temporal dynamics of a tree-killing beetle and its predator
Abstract Resolving linkages between local-scale processes and regional-scale patterns in abundance of interacting species is important for understanding long-term population stability across spatial scales. Landscape patterning in consumer population dynamics may be...
Cost sharing for pre-commercial thinning in southern pine plantations: Willingness to participate in Virginia’s pine bark beetle prevention program
Abstract Forest management that reduces southern pine beetle (SPB) risk benefits not only the landowners, but all who draw benefits from southern pine forests, including other owners whose risk is reduced by landscape-wide efforts. One such practice is pre-commercial...
Temperatures experienced by wood-boring beetles in the under-bark microclimate
Abstract Most studies of under-bark microclimate have been restricted to observations of a few coniferous trees in wooded locations. The findings of these studies may not generalize to deciduous hardwood trees, or to trees in urban environments. We addressed this...
Evaluation of phenological indicators for optimizing spring southern pine beetle (Coleoptera: Curculionidae: Scolytinae) trapping surveys
Abstract Since 1987, as many as 16 southeastern US states participate in a 4 wk. annual spring Dendroctonus frontalis (Zimmerman) (Coleoptera: Curculionidae) trapping survey. The purpose of the survey is to assess the current D. frontalis outbreak potential, and...

Ecological Impacts of Southern Pine Beetle
Abstract The southern pine beetle (SPB) is the most important biotic disturbance in southern pine forests and causes extensive changes to the forest environment. In this chapter we provide an overview of the ecological impacts of the SPB on forest conditions (the...
Amphibian and reptile responses to thinning and prescribed burning in mixed pine-hardwood forests of northwestern Alabama, USA
Abstract We evaluated the response of amphibians and reptiles to two levels of prescribed burning and three levels of thinning using a field experiment consisting of a before–after, control-impact, and factorial complete block design over a four year period in the...
