Obsidian Source

Using x-ray fluorescence (XRF) analysis from nearly 2,300 sourced obsidian artifacts in western Wyoming, southwestern Montana, and eastern Idaho, we demonstrate regional diachronic changes in access to and preference for particular obsidian sources throughout the West. We focus on both (I) long-term patterns of obsidian use that may inform us about the timing of precontact migrations of Numic (Shoshone) speakers into the Rocky Mountains and (2) the extent to which later contact among Native inhabitants and European immigrants was a mechanism for reducing elements of precontact mobility and exchange in the postcontact era. We view indigenous responses to contact in the study area as an active, strategic process with measurable material consequences. Despite a well-documented increase in mobility among local Native groups as a result of the introduction of the horse, our study demonstrates a restriction and reduction in Historic period source use in western Wyoming. We propose that changes in obsidian source use are a reflection of ethnogenesis and development of ethnographic bands as a response to culture contact among indigenous inhabitants and with Europeans.

Contrasting research approaches to managing mistletoes in commercial forests and wooded pasturesThis minireview is one of a collection of papers based on a presentation from the Stem and Shoot Fungal Pathogens and Parasitic Plants: the Values of Biological Diversity session of the XXII International Union of Forestry Research Organization World Congress meeting held in Brisbane, Queensland, Australia, in 2005.

Inundative Biological Control

Many mistletoe species are pests in agricultural and forest ecosystems throughout the world. Mistletoes are unusual “weeds” as they are generally endemic to areas where they achieve pest status and, therefore, classical biological control and broad-scale herbicidal control are usually impractical. In North American coniferous forests, dwarf mistletoe ( Arceuthobium spp.) infection results in major commercial losses and poses a public liability in recreation settings. Hyperparasitic fungi have potential as biological control agents of dwarf mistletoe, including species which attack shoots, berries, and the endophytic systems of dwarf mistletoe. Development of an inundative biological control strategy will be useful in situations where traditional silvicultural control is impractical or undesirable. In southern Australia, farm eucalypts are often attacked and killed by mistletoes ( Amyema spp.) in grazed landscapes where tree decline and biodiversity loss are major forms of land degradation. Although long-term strategies to achieve a balance between mistletoe and host abundance are promoted, many graziers want short-term options to treat severely infected trees. Recent research has revisited the efficiency and efficacy of silvicultural treatments and selective herbicides in appropriate situations. The results of recent research on these diverse management strategies in North America and Australia are summarized.
