Mountain pine beetle seasonal timing and constraints to bivoltinism (A comment on Mitton and Ferrenberg, "Mountain Pine Beetle Develops an Unprecedented Summer Generation in Response to Climate Warming")

Mountain pine beetle tree colonization typically occurs in July and August, with completion of a generation one (univoltinism) or two (semivoltinism) years later. In a 2012 publication, Mitton and Ferrenberg suggested that climate change resulted in an unprecedented generation between June and September (a summer generation), with a concomitant shift to two...

Do elevated temperature and CO₂ generally have counteracting effects on phenolic phytochemistry of boreal trees?

Global climate change includes concomitant changes in many components of the abiotic flux necessary for plant life. In this paper, we investigate the combined effects of elevated CO₂ (720 ppm) and temperature (+2 K) on the phytochemistry of three deciduous tree species. The analysis revealed that elevated CO₂ generally...

Dynamics of forest herbivory: quest for pattern and principle.

Herbivory on woody plants is highly variable in both space and time. This proceedings addresses one of its root causes, the highly intricate and dynamic relationships that exist between most herbivores and their host plants. It emphasizes that the consequences of herbivory both to the consumer and to the producer plant often balance on a razor`s edge--depending on...

Energy harvesting from wood floor vibration using a piezoelectric generator

Vibration can occur in wood floor systems as a consequence of a variety of human activities, ranging from common daily movements associated with individuals living in homes to high-intensity activities associated with sporting events that are held in large sports arenas. For example, the potential for harvesting energy from a wooden floor system in public buildings...

Ips typographus and Dendroctonus ponderosae models project thermal suitability for intra- and inter-continental establishment in a changing climate

Climate change is altering legacies of native insect-caused disturbances and contributing to non-native invasions globally. Many insect fitness traits are temperature dependent and projected climatic changes are expected to cause continued alterations in insect-caused tree mortality, with uncertain consequences for forest ecosystems and their management. Dendroctonus...

Effects of elevated CO₂ and shade on the decomposition of senesced tree foliage: impacts on microbial activity

We examined microbial respiration and carbon/nitrogen content of decomposing leaf material in microcosms used for growth studies of the treehole mosquito, Aedes triseriatus. Leaf material originated from birch and oak trees exposed to conditions of shade/sun and elevated/ambient levels of CO₂. Microbial respiration as measured...

Mountain pine beetle voltinism and life history characteristics across latitudinal and elevational gradients in the western United States

Substantial genetic variation in development time is known to exist among mountain pine beetle (Dendroctonus ponderosae Hopkins) populations across the western United States. The effect of this variation on geographic patterns in voltinism (generation time) and thermal requirements to produce specific voltinism pathways have not been investigated. The influence of...

Decay detection in red oak trees using a combination of visual inspection, acoustic testing, and resistance microdrilling

Arborists are often challenged to identify internal structural defects hidden from view within tree trunks. This article reports the results of a study using a trunk inspection protocol combining visual observation, single-path stress wave testing, acoustic tomography, and resistance microdrilling to detect internal defects. Two century-old red oak (Quercus rubra)...

Mountain pine beetle in high-elevation five-needle white pine ecosystems

Across western North America mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Curculionidae, Scolytinae), populations are growing at exponential rates in pine ecosystems that span a wide range of elevations. As temperature increased over the past several decades, the flexible, thermally-regulated life-history strategies of mountain pine beetle have allowed...

Chapter 7: Nondestructive Testing in the Urban Forest

Trees within an urban community provide measurable aesthetic, social, ecological and economic benefits. When growing normally and stably, they contribute to making a city more livable and comfortable for its inhabitants. However, as large physical structures in close proximity to people and property, their failure can cause harm. The science of tree stability analysis...

Effects of climate change on ecological disturbances [Chapter 8]

This chapter describes disturbance regimes in the Intermountain Adaptation Partnership (IAP) region, and potential shifts in these regimes as a consequence of observed and projected climate change. The term "disturbance regime" describes the general temporal and spatial characteristics of a disturbance agent (e.g., insects, disease, fire, weather, human...
