Long-Term Changes in Southern Utah Upland Shrub Communities: A Study in Repeat Photography

To evaluate long-term range conditions in southern Utah, 1,879 repeat photographs were made on the Dixie and Fishlake National Forests, and adjoining lower elevation BLM and private lands. Repeat photographs were also made in Zion National Park, Cedar Breaks National Monument, and Bryce Canyon National Park where livestock grazing has been prohibited for many years. Of the total, 926 photo-pairs depict sagebrush (Artemisia spp.) communities and 471 depict mountain brush associations (Cercocaprus ledifolius, C. mountanus, Amelamchier utahensis, Quercus gambelii, Prunus virginiana). Sagebrush decreased in 261 photosets, increased in 386 and remained unchanged in 279, while mountain brush decreased in 10 photopairs, increased in 440, and showed no change in 21. Sagebrush increased on all sites that had been treated and planted to crested wheatgrass (Agropyron desertorum) during the 1950s to 1960s. Most of the decline in sagebrush was due to invasion by pinyon (Pinus spp.) and/or juniper (Juniperus spp.), while an absence of fire is the most likely reason mountain brush increased. The observed changes have major implications for wildlife, and especially mule deer (Odocoileus hemionus) where sagebrush winter ranges have been lost or where mountain brush has grown beyond the reach of browsing animals. All repeat-photosets and descriptive text have been placed on Utah State University’s Extension website and can be accessed at http://extension.usu.edu.rra

Management Philosophies and Lodging Success: An Exploratory Study

This research investigates the impact of lodging professionals’ management philosophy practices on career success. The study assesses the practice of management philosophies by lodging professionals and examines if these practices differ among respondent groups, as well as explores the influence of executive philosophies on career success. Findings indicate that differences exist among respondent groups based on age, property affiliations and position. Moreover, executives who instill in employees customer-centeredness and engage in open sharing of information with employees experience relatively high monetary success. However, results suggest that lodging professionals’ practices of these management philosophies are not rewarded until reaching senior status

Parallel hippocampal-parietal circuits for self- and goal-oriented processing

The hippocampus is critically important for a diverse range of cognitive processes, such as episodic memory, prospective memory, affective processing, and spatial navigation. Using individual-specific precision functional mapping of resting-state functional MRI data, we found the anterior hippocampus (head and body) to be preferentially functionally connected to the default mode network (DMN), as expected. The hippocampal tail, however, was strongly preferentially functionally connected to the parietal memory network (PMN), which supports goal-oriented cognition and stimulus recognition. This anterior-posterior dichotomy of resting-state functional connectivity was well-matched by differences in task deactivations and anatomical segmentations of the hippocampus. Task deactivations were localized to the hippocampal head and body (DMN), relatively sparing the tail (PMN). The functional dichotomization of the hippocampus into anterior DMN-connected and posterior PMN-connected parcels suggests parallel but distinct circuits between the hippocampus and medial parietal cortex for self- versus goal-oriented processing

A somato-cognitive action network alternates with effector regions in motor cortex

Motor cortex (M1) has been thought to form a continuous somatotopic homunculus extending down the precentral gyrus from foot to face representation
