AbstractThe xystodesmid milliped tribe Sigmocheirini occupies a band along the western slope of the Sierra Nevada Mountains and eastern fringe of the San Joaquin Valley from Placer to Kern counties, California. It is comprised of two genera, Sigmocheir Chamberlin, with three species occurring from Placer to Tulare counties, and the monotypic Ochthocelata gen. n., the sole component, O. adynata sp. n., occurring in northern Kern County. The species of Sigmocheir display a distinctive, trimaculate pigmentation pattern with yellow middorsal and paranotal spots; the coloration of O. adynata is unknown. Sigmocheir calaveras Chamberlin is a senior name for S. dohenyi Chamberlin, the spelling of which was subsequently corrected to danehyi and assigned to the new genus, Tuolumnia, a synonym of Sigmocheir. Sigmocheir furcata sp. n. is proposed for forms from the northern generic range. The southernmost species is S. maculifer (Chamberlin), comb. n., transferred from Harpaphe Cook. The Sigmocheirini are related to the sympatric tribe Xystocheirini; relationships within Sigmocheir are hypothesized as maculifer + (calaveras + furcata).

Abstract Fire officials are dismayed when victims of wildfire blame fire fighters and others responsible for fire management for damage resulting from uncontrolled fires. This is in spite of the fact that wildfire damage is a consequence of dynamic interactions among natural factors (wind, temperature, location of wildfire, topography, etc.) and human factors (past land management, promptness of firefighting activities, extent of homeowners' defensible space, etc.). Fire and land managers do not typically understand why and how the victims arrive at such oversimplified, and in some cases inaccurate, conclusions about wildfire causation. Attribution theory in social psychology provides a framework for understanding the mechanisms of these blaming processes. In this study, both quantitative and qualitative approaches were used to explore how people who live in wildfire hazard zones and experienced wildfire, perceive the causes of wildfire damage. In the spring of 1999, a prefire survey was conducted in the western slope of the Sierra Nevada Mountains, an area where numerous wildfires are recorded nearly every year. This was followed by a postfire survey in two communities that actually experienced a fire that season. In addition, qualitative interviews were carried out in these two affected communities. Results suggest that people who experienced wildfire tended to attribute the cause of wildfire damage to factors associated with fire officials and nature and did not attribute fire damage to their own actions (or inactions). The implications of these attributions are discussed as are recommendations for future fire education and communication. West. J. Appl. For. 19(3):184–194.

Abstract To understand the influence of the Sierra Nevada on the water cycle in California the authors have analyzed low-level winds and water vapor fluxes upstream of the mountain range in regional climate model simulations. In a low Froude number (Fr) regime, the upstream low-level wind disturbances are characterized by the rapid weakening of the crosswinds and the appearance of a stagnation point over the southwestern foothills. The weakening of the low-level inflow is accompanied by the development of along-ridge winds that take the form of a barrier jet over the western slope of the mountain range. Such upstream wind disturbances are either weak or nonexistent in a high-Fr case. A critical Fr (Frc) of 0.35 inferred in this study is within the range of those suggested in previous observational and numerical studies. The depth of the blocked layer estimated from the along-ridge wind profile upstream of the northern Sierra Nevada corresponds to Frc between 0.3 and 0.45 as well. Associated with these low-level wind disturbances are significant low-level southerly moisture fluxes over the western slope and foothills of the Sierra Nevada in the low-Fr case, which result in significant exports of moisture from the southern Sierra Nevada to the northern region. This along-ridge low-level water vapor transport by blocking-induced barrier jets in a low-Fr condition may result in a strong north–south precipitation gradient over the Sierra Nevada.
