Simulated Effects of Two Fire Regimes on Bighorn Sheep: The San Gabriel Mountains, California, USA

Simulated Effects of Two Fire Regimes on Bighorn Sheep: The San Gabriel Mountains, California, USA

In the San Gabriel Mountains of southern California, USA, bighorn sheep (Ovis ca- nadensis) occupy winter-spring ranges domi- nated by chaparral vegetation for at least four months each year. Chaparral is a fire-adapted community characterized by moderate-to-long fire return intervals that are separated by in- tense crown fires; such fires reduce shrub can- opy cover and result in an ephemeral (Biswell et al. 1952, Hanes 1971, Keeley and Davis 2007) and highly nutritious herbaceous forage crop (Biswell et al. 1952, Taber and Dasmann 1958) that enhances habitat quality for bighorn sheep by increasing nutrient availability and visual openness (Holl et al. 2004, Bleich et al. 2008). Between fires, plant succession leads to increases in shrub height and canopy cover, both of which reduce habitat suitability by re- stricting access and the ability of those special- ized ungulates to detect predators.

Regional mapping of the crustal structure in Southern California

Regional mapping of the crustal structure in Southern California

Final discussion focuses on the relatively simple seismic velocity structure derived for the southern end of our transect beneath the southern part of Santa Clarita Valley and the San Fernando Pass areas. As shown on the geologic cross section the structure is much more com- plex than that of the seismic velocity model. Most notable is a lack of any signature for the San Gabriel fault, nor the Santa Susana-Sylmar thrust system. Nor is there any expression of the considerable basement relief beneath the Neogene strata of the area that is documented by drill hole data. In addition to the problem of poor resolution at the extremities of our seis- mic model, the most viable explanation for this is that upper plate crystalline rocks above the Vincent thrust of this region are also highly fractured and hydrated, and thus yield seismic ve- locities in a range below those of coherent basement rocks and overlapping with those of clastic sedimentary rocks. Such a textural state is born out by observations of crystalline rocks which constitute the western end of the San Gabriel Mountains, and which project westwards beneath the adjacent San Fernando Pass area. As noted earlier the history of upper plate crystalline rock fracturing, hydration and attenuation began during or shortly after initial schist underthrusting, and has been accentuated by Neogene to Recent extensional, strike-slip and compressional de- formations. The effects of this near pervasive textural and structural degradation of much of the Southern California region crystalline basement are well expressed along the entire length of our transect by their consistently low P-wave velocities as compared to what is known to typify texturally and structurally coherent continental basement rocks.

Naturalization of Sequoiadendron giganteum (Cupressaceae) in Montane Southern California

Naturalization of Sequoiadendron giganteum (Cupressaceae) in Montane Southern California

For nearly a century the United States Forest Service, established in 1905 with Gifford Pinchot (1865–1946) as its first Chief, actively planted areas with species that were alien to the area. Burns and Sauer’s (1992: 49) history of the Forest Service and other agencies introducing non-native conifer species to the San Gabriel Mountains is illustrative: The Forest Service planted in the Angeles National Forest (established 1892) about 100,000 seedlings of conifer species yearly in 1907 and the next few years in an ineffective attempt to reforest the San Gabriels. ‘‘Direct seeding was tried but quickly abandoned as futile.’’ Burns and Sauer tabulated 44 conifer species and three hybrids alien to the area, for a total of about 647,000 seedlings planted: Pinus attenuata with 377,000 plantings and P. halepensis Mill. with 64,300 head the list; Sequoiadendron giganteum with 22,900 plantings ranks eighth. However, none of the 47 taxa listed ‘‘are invading adjacent natural habitats’’ of chaparral and montane forest. After fires, only P. canariensis C.Sm. resprouted, and only P. attenuata estab- lished seedlings, but these were ‘‘too few … to restore the stands.’’

Genome wide association study to identify genetic determinants of severe asthma

We then went on to assess the contribution of previously identified asthma susceptibility loci in patients with severe disease reported by the recent GABRIEL study. 14 As the GABRIEL study is currently the largest published association study investigating the genetic determinants of asthma, we aimed to determine if these signals also contribute to disease susceptibility in our severe asthma cohort. Individuals in AUGOSA were included in the total case subjects in the GABRIEL study. However, as they only constitute a relatively Figure 1 Quantile e quantile plot and

Symbolic Deterritorialization: The Case of Gabriel Orozco

Symbolic Deterritorialization: The Case of Gabriel Orozco

In a global context the artistic production has developed its critical processes from the inclusion and participation of audience in the works of art. Somehow the expansion and compression of space-time is reflected in the characteristics of many artists whose work is based on the occupying, mapping and reinterpreting of the spaces that they appropriate. This article tries to analyze the spatial and temporal turn defined by the works of artist Gabriel Orozco, The individual and collec- tive memories, spaces of history, politics and culture are signified by the act of symbolic deterrito- rialization and reterritorialization. The article also analysed the phenomenological and material treatment of objects of Gabriel Orozco in his temporal frequency and perceptual reinterpretation in the context of cultural and political globalization in order to confront symbolic deterritorializa- tion as a resource of his artistic production.

In Memoriam: Gabriel Wilner

In Memoriam: Gabriel Wilner

I met Gabriel for the first time in July 1965. I was an assistant to Professor Charles Chaumont who, in addition to teaching international law at my university, was Secretary General of the Curatorium of the Academy of International Law in The Hague. The previous year, the Curatorium decided to hire what was at the time known as a “Tutorial Associate” (the title was subsequently changed to “Director of Studies”) in order to assist the professors who were invited to teach during the summer sessions in the preparation of their seminars. Gabriel was hired for the 1964 session. The experience was successful, and the following year the Curatorium decided to appoint a second Tutorial Associate. Professor Chaumont asked me if I would be interested. I answered affirmatively, although I was working on a book at the time and wished to devote the summer vacation to finishing it. Professor Chaumont assured me that the task was not very demanding and that I would have plenty of free time to work on my book. Moreover, the prospect of spending six summer weeks in this pleasant seaside city was attractive in itself, and the job seemed interesting. So I accepted.

"Il nostro moderno Algardi": Giuseppe Maria Mazza, scultore bolognese tra Sei e Settecento

"Il nostro moderno Algardi": Giuseppe Maria Mazza, scultore bolognese tra Sei e Settecento

quell’inventario si riferisce invece alla terracotta raffigurante lo stesso soggetto che oggi si conserva nel Museo Internazionale delle Ceramiche di Faenza e che riporta sul retro le iniziali di Alessandro Fava. A tre anni di distanza Giuseppe torna a confrontarsi con lo stesso soggetto, nello stesso materiale ma con dimensioni maggiori e inserendo alcune varianti nell’iconografia e nella postura del santo. Se nella precedente prova Giovanni Battista era descritto da un’iconografia più articolata che lo individuava simbolicamente nel ruolo di ultimo profeta e primo santo e quindi anello intermedio tra il Vecchio e il Nuovo Testamento, in questa terracotta la descrizione iconografica appare svolgersi secondo tradizione: al serpente sul retro che procede tortuosamente sul basamento e alla lucertola che si arrampica sulla roccia, presenti anche nella terracotta di Faenza, si aggiunge l’agnello, accostato al fianco sinistro del santo che lo sostiene con la mano. In entrambe le terrecotte il Battista è figurato seduto su di una roccia, nudo sino alla cintola, con in vita un drappo pesante bordato di pelliccia, ma la postura in cui è ritratto il santo di Palazzo Venezia appare maggiormente complessa e forzata in particolare nella parte superiore del corpo. La posizione e la tornitura delle gambe risulta simile, anche se qui sono maggiormente distanziate e la destra appare più flessa, il busto in torsione si piega sull’addome, le braccia, entrambe mutile, compiono movimenti contrapposti: il braccio destro era sollevato nel gesto di ostensione tipico del precursore, mentre il braccio sinistro porta la mano, ancora visibile, a protezione dell’agnello (oggi acefalo e mutilo della zampa posteriore sinistra), che si appoggia con le zampe anteriori sulla gamba del santo. Quest’opera che si qualifica come un’esercitazione di studio, rivela un progresso nella formazione dello scultore verso un maggiore naturalismo che si evidenzia nella resa plastica del modellato così come nella definizione del volto. Ad esempio i muscoli intercostali sono in risalto ma i contorni appaiono meno rigidi e secchi delle precedenti prove; il volto, dai tratti simili a quello del San Giovanni Battista di Faenza (nella forma, nelle labbra piccole e carnose e nella prominenza del mento piccolo e arrotondato) è però maggiormente caratterizzato in senso realistico e rivela una minuziosa indagine dal vero: nelle rughe asimmetriche che solcano la fronte, nella peluria dell’arcata sopraccigliare, negli occhi, in cui sono incisi la pupilla
