Out of the ordinary : Anne Ryan and collage

Anne Ryan (1889-1954) was an active member of New York’s vibrant avant-garde art community during the tumultuous period marked by World War II. Ryan participated in the famed 1951 “Ninth Street Show,” and was an early member of Betty Parsons’s legendary stable of artists. She is not widely known today, however, and her influence is rarely acknowledged. Ryan is primarily known for her abstract collages—works that are frequently linked to Abstract Expressionism.

Modernist Success in a Postmodern Failure: Jackson Pollock and Abstract Expressionism, the Avant-Garde and the Ascension of Late Capitalism, Art after 1945

It is hard to imagine the magnitude of the events at the end of World War II. The thought produced in the face of a myriad of deaths is almost unfeasible sixty years after the fact, but the energy was integral to the changing social landscape. Because of the country's prominence in and fortitude after the war, the U.S. was left responsible for reshaping and rejuvenating the international landscape that was destroyed by the years of brutal fighting and vile contestation. The American establishment was granted a major opportunity to establish itself amongst the global leaders. Such a grand responsibility must account for the multiplicity of thought that arises in such a decisive moment. In order to align the Abstract Expressionist art movement with the intersection of the intense, multifaceted thought developed during the postwar period, the following will discuss the political, philosophical, economic, and art historical overlap that occurred in the mid to late 1940s in the hopes of illustrating the fertility yet lingering problems associated with the restructuring of the world with America at the helm. In this way, the duration of the Abstract Expressionist moment will be better understood for both its triumphs and downfalls.

Bat survey of the lower Juruena River and five new records for the state of Mato Grosso, Brazil

ABSTRACT The northern Brazilian state of Mato Grosso is considered an important biogeographical region, but has many sampling gaps. Apart from the well-documented non volant mammal community in the region, the bat fauna still poorly recorded. The aim of this study was to record the bat species of Juruena National Park, northern Mato Grosso, Brazil. Nineteen sites were sampled using mist-nets placed at ground level and near potential bat roosts. We collected 115 individuals belonging to 35 species and five families, which increased the number of species known for Mato Grosso´s Amazon from 86 to 91. The five new records were: Peropteryx kappleri, Peropteryx leucoptera, Lonchorhina inusitata, Tonatia saurophila, and Artibeus concolor. Our results pointed out the necessity of more studies in order to better estimate the bat diversity in northern Mato Grosso.

Tometes camunani (Characiformes: Serrasalmidae), a new species of phytophagous fish from the Guiana Shield, rio Trombetas basin, Brazil

Uma espécie nova de Serrasalmidae, Tometes camunani, é descrita para as drenagens superiores da bacia do rio Trombetas, estado do Pará, Brasil. A espécie nova distingue-se dos congêneres pela presença de uma ligeira concavidade no neurocrânio na altura do frontal (vs. concavidade ausente, perfil dorsal do neurocrânio reto). Também pode ser adicionalmente distinguido dos seus congêneres por possuir dentes com a cúspide central mais alta e cume agudo (vs. cúspide central mais baixa e com cume arredondado em T. trilobatus), a boca terminal (vs. boca orientada para cima em T. lebaili), e 12-26 espinhos pré-pélvicos (vs. 0-9 em T. makue). A espécie nova é estritamente reofílica, como as demais espécies de Tometes, e ocorre exclusivamente nas zonas encachoeiradas dos rios de escudo, biótopos complexos, frágeis e ameaçados por ações antropogênicas. Uma chave de identificação para as espécies do grupo Myleus é apresentada.

Description of a new species of Ituglanis (Siluriformes: Trichomycteridae) from Serra dos Carajás, rio Tocantins basin

Uma espécie nova de Ituglanis é descrita da bacia do rio Tocantins, Pará, Brasil. Ituglanis ina, espécie nova, é facilmente diferenciada das congêneres por apresentar uma barra vertical escura sobre a base dos raios da nadadeira caudal (vs. sem barras na base da nadadeira caudal); e por apresentar linha lateral seguida por uma linha de diminutos neuromastos até a região do flanco, abaixo da nadadeira dorsal, ou até o pedúnculo caudal (vs. sem neuromastos após a linha lateral). Ituglanis ina distingue-se, também, por uma combinação de caracteres relacionados ao padrão de coloração e morfologia. Comentários sobre o relacionamento das espécies e grupos de espécies de Ituglanis são apresentados.

A new species of Scinax Wagler, 1830 (Anura: Hylidae) from the middle Amazon river basin, Brazil

Uma nova espécie de hilídeo do gênero Scinax é descrita e ilustrada. O novo táxon foi encontrado na Amazonia, região norte do Brasil, municípios de Maués e Careiro da Várzea, Estado do Amazonas. A nova espécie é caracterizada pelo tamanho moderado (machas com media de comprimento rostro-cloacal de 36.3mm); corpo robusto; mancha axiliar e inguinal grande, laranja bordeada de preto; e saco vocal bilobado. Essa nova espécie foi encontrada em floresta primária e secondária sobre ramos de arbustos e árvores sobre ou próximo a poças permanentes ou áreas alagadas.

Closer to life : the work of sari dienes

Like many of her female contemporaries, artist Sari Dienes’s contributions to the art historical dialogue have been largely overlooked in favor of her male counterparts. Often seen as a mentor and mother figure to neo-Dada artists Jasper Johns and Robert Rauschenberg, Dienes was an active member of the New York avant-garde circle surrounding composer/choreographer duo John Cage and Merce Cunningham in the 1950s and 1960s. These social relationships are central to the existing discourse on Sari Dienes, while her work remains little discussed. The fact that her dynamic, ever-changing style lacked aesthetic consistency was commonly lamented by notable figures such as Betty Parsons, however, I argue that Dienes’s diverse oeuvre is unified by her philosophies on art and life. The unification of art and life, denoted clearly by Dienes’s use of the found object, experimentation and chance happenings, and sensory experience, marks her as an innovator and catalyst in the neo-Dada movement as well as in other experimental art endeavors that took place in the aftermath of Abstract Expressionism.

State Space Analysis of Forest Fires

This paper studies forest fires from the perspective of dynamical systems. Burnt area, precipitation and atmospheric temperatures are interpreted as state variables of a complex system and the correlations between them are investigated by means of different mathematical tools. First, we use mutual information to reveal potential relationships in the data. Second, we adopt the state space portrait to characterize the system’s behavior. Third, we compare the annual state space curves and we apply clustering and visualization tools to unveil long-range patterns. We use forest fire data for Portugal, covering the years 1980–2003. The territory is divided into two regions (North and South), characterized by different climates and vegetation. The adopted methodology represents a new viewpoint in the context of forest fires, shedding light on a complex phenomenon that needs to be better understood in order to mitigate its devastating consequences, at both economical and environmental levels.

Ommatius nanciae, a new species from Ecuador (Diptera, Asilidae, Ommatiinae)

A new species of Phrixotrichus (Araneae, Theraphosidae) from southwestern Argentina and new distributional data for P. vulpinus

ABSTRACT A new species of Phrixotrichus Simon, 1889, P. pucara sp. nov., is described and illustrated based on a male from Pucará river, Neuquén province, Argentina. Male can be distinguished from all other species of the genus by the presence of a long strong spine on inner face of prolateral branch of tibial apophysis; also, it differs from P. scrofa (Molina, 1788) and P. vulpinus (Karsch, 1880) by a serrated prolateral keel of the male palpal bulb. Male resembles P. jara Perafán & Pérez-Miles, 2014 but can be distinguished by the uniform color on dorsal cephalothorax and by the palpal organ morphology being wider on the bulb base and embolus shorter and thicker, with the tip of embolus not so directed retrolaterally and prolateral keel bearing a serrated edge with three teeth. Additionally, P. vulpinus is reported for the first time for Argentina along with new distributional data.
