Important Parasite

The mistletoe Psittacanthus macrantherus Eichl. (Loranthaceae) is an important parasite of pines (Pinus spp., Pinaceae) in Mexico (1). It has been reported to parasitize Pinus engelmannii Carr., P. herrerai Mart., P. lawsonii Roezl ex Gord. & Glend., P. lumholtzii Robins & Fern., P. oocarpa Schiede, and P. pseudostrobus Lindl. (1). During July 2005, we found this mistletoe parasitizing P. devoniana Lindl. and Quercus castanea Nee near Route 40 in Sinaloa, Mexico approximately 12 km west of El Palmito (23°30′N, 105°07′W, elevation 1,900 m). The mistletoe was common in P. devoniana, and some trees were severely infected (>10 plants per tree). However, no mortality associated with mistletoe infection in P. devoniana was observed. Only one infected tree of Q. castanea was observed in this area and it was not severely infected. We also observed this mistletoe on P. douglasiana Mart. along Route 40 west and east of El Palmito, but no specimens were collected because plants were very high in the crowns of the infected trees. To our knowledge, this is the first report of this mistletoe parasitizing P. devoniana, P. douglasiana, and Q. castanea (1). Specimens of Psittacanthus macrantherus from P. devoniana and Q. castenea have been deposited at the Deaver Herbarium (ASC), Northern Arizona University, Flagstaff (Accession Nos. 79534 and 79535).

This case chronicles the beginnings of an enrollment management transformation currently underway at The Extended Campuses of Northern Arizona University. After flat enrollments for three plus years, the organization executed a phased plan to alter the university’s enrollment trajectory. A complete reorganization, an intentional effort to operationalize enrollment marketing best practice, and the establishment of a data-driven organization comprise the foundations of the first phase of the plan. While specific to Northern Arizona University, the case will also highlight six foundations for initiating any enrollment management transformational journey.

Blended Course

Facetiously described as the “third generation” of distance learning, blended learning is now the new kid on the block in the deployment of technology to support teaching and learning. Its versatility as a pedagogical strategy for creating learner-centered instruction lies in the capacity to exploit the potentials of both the traditional face-to-face instruction and online learning modality in order to provide students with multiple pathways of learning. Yet, developing a blended course to take advantage of these duo capabilities is a monumental challenge for faculty. This chapter presents an analysis of approaches and models employed by faculty at Northern Arizona University to develop and deliver two blended courses as part of the institution's strategy of using technology to enhance undergraduate student engagement and retention. The analysis shows that a multimodal approach that infuses technologies and media and a proactive institutional policy in favor of blended learning, coupled with strategic faculty development, provides the best pathway to developing robust blended courses that are truly learner-centered.

Statistical Summary

The Public Utility District No. 2 of Grant County, Washington, USA, in collaboration with the National Renewable Energy Laboratory and Northern Arizona University, conducted an analysis of the impact wind integration on their hydropower dominant generation system. Wind power penetration levels of 12 MW (2.0%), 63.7 MW (10.4%) and 150 MW (24.6%) were considered. For the 2006 study year, a statistical summary of the changes in the regulation and load following requirements expected due to wind variability was conducted. The results demonstrated that the impact of wind power upon minute-to-minute regulation requirements is small, and small to modest on the load following requirements. However, changes in the distribution of load following hourly changes could result in infringement upon system constraints. A chronological simulation of preschedule (i.e. day ahead) planning was therefore conducted indicating an increased incidence of constraint “exceedences.” The nature of the increase in exceedences is presented and discussed.

Common Parasite

The mistletoe Psittacanthus angustifolius Kuijt (Loranthaceae) is a common parasite of pines in Honduras (2). In March we observed this mistletoe parasitizing a pine that Farjon and Styles (1) have classified as Pinus tecunumanii Eguiluz & J. P. Perry 4 km south of Jitotol, Chiapas, Mexico. The taxonomy of this host in Chiapas is controversial as Perry (3) classifies the Chiapas populations of this pine as Pinus oocarpa var. ochoterenai Martinez. We also observed P. angustifolius on P. oocarpa Schiede 4 km north of Jitotol. In addition, we found this mistletoe parasitizing Pinus maximinoi H. E. Moore approximately 15 km west of Ocosingo, Chiapas. In Guatemala, we observed P. angustifolius on P. oocarpa at several locations north and south of La Cumbre, Department Baja Verapaz. This mistletoe appears to be less common in Chiapas and Guatemala than it is in Honduras. We did not observe this mistletoe damaging its pine hosts in Mexico or Guatemala. This is the first report of P. angustifolius in both Mexico and Guatemala and the first report of this mistletoe on Pinus tecunumanii (or Pinus oocarpa var. ochoterenai). Specimens of P. angustifolius from the above pine hosts have been deposited at the Deaver Herbarium, Northern Arizona University, Flagstaff. References: (1) A. Farjon and B. Styles.
