Species Groups

Species of North American Cybaeus L. Koch (Araneae: RTA clade: Cybaeidae) are common moist-forest spiders classified in Holarctic and Californian clades. Here, in the second paper in a planned series reviewing the six Californian clade species groups, we review the species of the aspenicolens group. We recognize five species in two subgroups: the aspenicolens subgroup (Cybaeus aspenicolens Chamberlin & Ivie, C. blasbes Chamberlin & Ivie, and C. coylei Bennett spec. nov.) and the fraxineus subgroup (C. fraxineus Bennett spec. nov. and C. thermydrinos Bennett). The species of the aspenicolens group have very restricted distributions on the western slopes of the central and southern Sierra Nevada mountain range from Tuolumne County south to northern Kern County in east central California, U.S.A. Descriptions, illustrations, distribution maps, and an identification key are provided for the five species as well as a discussion of conservation issues of relevance to the group.

There is considerable divergence of opinion among authorities regarding the distribution of the practice of irrigation by the prehistoric Indians of the Southwest. Martin, Quimby, and Collier (1947, p. 168) write that the irrigation of the Hohokam of central and southern Arizona is the only known instance of canal irrigation in pre-Columbian North America. Thomas (1948, p. 10), however, writes that canal system irrigation was not limited to the area of the Hohokam but that “in many ravines and valleys in Arizona, New Mexico, Colorado, Utah and Southern California are found the remains of canal systems which tapped the natural streams and carried water to the numerous small farms.” Wittfogel (Wittfogel and Goldfrank, 1943), has assembled published evidences of irrigation in the Anasazi area, north of the Hohokam, such as its practice west of the Wasatch Mountains in the Great Basin portion of Utah, described by Steward.

AbstractSediment records from two lakes in the east-central Sierra Nevada, California, provide evidence of cooling and hydrological shifts during the Younger Dryas stade (YD; ~ 12,900–11,500 cal yr BP). A chironomid transfer function suggests that lake-water temperatures were depressed by 2°C to 4°C relative to maximum temperatures during the preceding Bølling–Allerød interstade (BA; ~ 14,500–12,900 cal yr BP). Diatom and stable isotope records suggest dry conditions during the latter part of the BA interstade and development of relatively moist conditions during the initiation of the YD stade, with a reversion to drier conditions later in the YD. These paleohydrological inferences correlate with similar timed changes detected in the adjacent Great Basin. Vegetation response during the YD stade includes the development of more open and xeric vegetation toward the end of the YD. The new records support linkages between the North Atlantic, the North Pacific, and widespread YD cooling in western North America, but they also suggest complex hydrological influences. Shifting hydrological conditions and relatively muted vegetation changes may explain the previous lack of evidence for the YD stade in the Sierra Nevada and the discordance in some paleohydrological and glacial records of the YD stade from the western United States.

Abstract This article examines an Indigenous origins narrative from central California. The text is an oral narrative about the theft of the sun by Coyote, recorded in the Central Sierra Miwok language. The article presents a formal analysis of the structure, language, and poetics of the text from the perspective of ethnopoetics, focusing on structural and lexical metaphors developed for describing the pathway of the sun. It then offers reflections on the ethnogeography and worldview presented in the text, linking it to Penutian migrations from the western Great Basin into central California’s Sierra Nevada several thousand years ago. The article also provides a general contextualization of the themes of the text in relation to California and western North American coyote stories and origins stories more generally.

Analysis Of Variation

This is a continuation of a study on geographical variation of the Elaphrus americanus Dejean species complex. This paper is devoted to E. finitimus Casey, which includes at least seven populations: White Mountains of California, Colorado Plateau, western Great Basin, western Arizona, central California, southern California, and southern Sierra Nevada. Three main groups of populations were recognized by means of numerical taxonomic analyses: White Mountains of California (one population), Intermontane (Colorado Plateau and western Great Basin), and southwestern (remaining four populations). The above groups were discerned from clustering by UPGMA (unweighted pair group using arithmetic averages) of Mahalanobis distances, and are characterized in a discriminant analysis. Other geographically distinct populations were recognized by univariate analysis of nominal characters. All seven populations are allopatric and are isolated presently from one another by vast expanses of dry regions (prairies and piñon–juniper woodlands), or by different life zones with altitude. We postulated that during the glacial phases of the Pleistocene similar barriers existed, though the gaps were narrower than at present. The reconstructed glacial ranges of these populations offer a hypothesis as to the origin of some populations, and direction of limited gene flow between some populations.

Abstract We have computed synthetic Wood-Anderson seismograms for over 1100 arrivals at 10 three-component, broadband digital stations in the UNR western Great Basin-eastern Sierra Nevada network. These represent all the available records from local earthquakes over magnitude 3.5 between 1990 and June of 1993, plus selected events of smaller magnitude. There were 77 events ranging in magnitude from 2.2 to 5.9, including four events over magnitude 5. The distances considered ranged from 15 to 600 km, with the best-represented range being from 30 to 450 km. We invert these measurements to determine distance and station corrections appropriate for a local-magnitude scale, constrained by Richter's original definition that an earthquake of ML = 3 will cause a 1-mm zero to peak deflection of the Wood-Anderson seismogram at 100 km from the epicenter. The results between 30 and 450 km were essentially independent of choice of curve-fitting parameters. In the 30- to 500-km distance region, the smooth distance-correction curves were very similar to that determined by Richter (1958), which is still used for southern California earthquakes. We propose to use Richter's distance-correction curve in reporting amplitude magnitudes from our digital network.
