Ampliamos la distribución geográfica de Ctenoblepharys adspersa (Liolaemidae), una especie de saurio endémico y amenazado del desierto peruano. Nuestro nuevo registro extiende la distribucion de esta especie en 60 km (línea recta) de la localidad más oriental previamente conocida, la Reserva Nacional de Paracas. Registramos dos tipos de hábitat nuevos para C. adspersa al interior de las estribaciones andinas e identificamos las plantas nativas asociadas a sus hábitats. Además, revisamos el estado de conservación de esta especie y los desafíos que implican su conservación, resaltando que la mayoría de las poblaciones son vulnerables a los impactos en su hábitat producto del desarrollo de infraestructura urbana y/o agrícola

El presente artículo consiste en una bitácora y divagación reflexiva a partir de la revisión y puesta en diálogo de dos proceso de investigación artística desarrollados entre los años 2014-2016 y 2019-2020, en torno al Oasis de Niebla de Alto Patache, Desierto de Atacama, Región de Tarapacá (Chile). Articulando nodos especulativos entre procesos diferidos espacial y temporalmente, el artículo busca establecer conexiones y derivas entre un primer proceso de investigación mediante metodología de trabajo de de exploración de campo, y un segundo proceso de investigación mediante metodología de análisis de crónicas y archivos históricos. De esta manera, el artículo va hilvanando preguntas y relaciones entre la calidad material, sentidos simbólicos y denominación que da nombre al fenómeno de niebla costera llamada “camanchaca”, transitando también por las nociones de desierto, frontera y visibilidad, y reflexionando sobre sus implicancias en la configuración del imaginario paisajístico en el desierto tarapaqueño.

The occasion (1987), a novel whose intrigue is located in the last decades of the 19th century, investigates the progressive disenchantment of the Santa Fe plain in the process of modernization based on the successive failures of the spiritual in its different versions -magic, mystery and fortune telling- and the deviation of certain romantic and sublime coordinates of the landscape. For this, the writing flies over and juxtaposes, among many others, Darwin's geological fiction, the theosophical and nationalist concerns of Lugones 'strange forces, Prado's expeditionary tales and Blanes' famous painting of yellow fever. Before the advance of the blind force of capitalist progress, we will try to observe how some of these heterogeneous desert fictions mutate and juxtapose, and in particular, how "magic" still resists in the precariousness of bodies.

Se describe el Xyletininae Desertinastes rotundus gen. nov. y sp. nov., de Chile, sobre la base de criterios morfológicos asociados principalmente a la forma de las antenas, del metaventrito y las características de la pilosidad.

Resumen. Se describen tres especies nuevas de Ptinidae del norte de Chile, Leptanobium atacamensis sp. nov., Leptanobium penai sp. nov. y Leptanobium trapichensis sp. nov. Se establece que la forma de las antenas y de la estructura genital del macho, particularmente la presencia/ausencia de espinas en el saco interno del lóbulo medio, son caracteres diagnósticos para diferenciar las especies del género. Adicionalmente se modifica y complementa la definición genérica original de Leptanobium y también se describe la hembra de este género.

Las representaciones territoriales han sido fundamentales en la formación de los Estados-Nación modernos. El presente trabajo analiza los modos por los que destacadas producciones cartográficas difundidas durante la formación del Estado-Nación argentino, contribuyeron a articular una imagen hegemónica del país. Específicamente, indaga los mecanismos por los cuales dichas representaciones fueron definiendo al espacio pampeano-patagónico como desierto y, consecuentemente, como un espacio diferenciado de la Nación. Considerando la tesis de que, históricamente, en Argentina la pregunta por el desierto envuelve un modo histórico y político de indagar sobre la relación con los pueblos indígenas, se reflexiona sobre los procesos de desmarcación de la mismidad argentina y marcación de la otredad indígena que dichas representaciones contribuyeron a articular. De este modo, se busca contribuir con el reconocimiento y contextualización de los procesos espacio-temporales de identificación colectiva y de control político de la diversidad sociocultural producidos históricamente en Argentina.

The Andean world is underexploited for tourism due to both the lack of infrastructure and the lack of its development as a product. Still, tourism exists and is, in some places, overwhelming. As such, it establishes itself in a double market game: 1) it offers hotel infrastructures and tours that are clearly a product for foreign tourists, and 2) it recreates a whole discourse on heritage. The Andean tourism market has three self-contained aspects, which address 1) the indigenous world, either the historical or the present, although without confusing them or making a connection between them, 2) the colonial world, and 3) a high quality natural environment. This work, based on a critical decolonial view and ethnography developed from field work, analyzes the game between discourse and social practice from the point of view of both visitors and locals, thereby recreating some of its paradoxes and contradictions. This analysis, obviously from a decolonial and political view, attempts to recover the epistemology of the south. [ABSTRACT FROM AUTHOR]

This article aims to investigate about the relationships between art, poetry, land, landscape and territory from the visual pieces of the artist, poet and teacher Mercedes Resch, a resident of Cura Malal, a rural town in the province of Buenos Aires, Argentina, a solid geographical and historical witness to the long process of national modernization that, from the beginning of the 20th century to its current neoliberal present, has exposed the land of that place to a violent patriarchal desertification campaign. The work of Mercedes Resch will allow us to explore, on the contrary, a landscape full of latent life forms that permanently resist the historical threat of the great drought. [ABSTRACT FROM AUTHOR]

Deserts, like any geographic setting, are not sites where geopolitical dramas simply unfold or "touch down"; rather, they actively constitute geopolitical orders. This article shows how taking deserts rather than states as an entry point can provide a unique lens on geopolitics, state making, and empire. Investigating the political lives of deserts requires asking how they are imagined, narrated, and connected across space and time, and with what effect. To do so, I consider one case of desert-to-desert connection: a long but little-known history of exchange between individuals and institutions in Arizona and the Arabian Peninsula. Taking one example from this history, I show how the "desert" as an environmental imaginary figured in the University of Arizona Environmental Research Laboratory's joint greenhouse and desalting plant, which was initiated in Abu Dhabi in the late 1960s. Primarily drawing from archival research in the United Arab Emirates (UAE) and Arizona, I also show how this project fit into shifting geopolitical relations in the Arabian Peninsula's colonial relations, the rise of the UAE as an independent state, and the role of experts working in the service of broader political agendas of the state and the academy, as well as their own self-interest.

Introducción y objetivos: El tránsito de vehículos sobre el terreno de áreas protegidas, constituye una amenaza al patrimonio natural que debe ser evaluada. El alto costo operativo de monitorear estas actividades hace que sea necesario desarrollar alternativas de evaluación rápidas y simples que permitan tener un primer parámetro de tendencias. Mediante freeware y técnicas básicas, se propone como caso de estudio evaluar las huellas vehiculares durante dos períodos (2004 y 2018) y su potencial impacto en la vegetación del área protegida Loma de Las Tapias, San Juan, Argentina. M&M: Empleando la zonificación florística preexistente y dos sets de imágenes satelitales (2004-2018), se cuantificaron las huellas vehiculares con una grilla, cuyos cuadros fueron categorizados según: ausencia de huellas; huellas antiguas (2004); huellas nuevas (2018) y huellas reincidentes (2004-2018) sobre las diferentes comunidades vegetales. Resultados: Actualmente, de los 223 cuadros que constituyen la grilla, solo el 35 % no posee huellas vehiculares, mientras que el 13,9 % posee únicamente huellas antiguas, el 30 % huellas reincidentes y el 21,1 % restante posee huellas vehiculares nuevas. Por lo tanto, se observa un claro incremento de huellas durante el período evaluado, que fue uniforme en todas las unidades florísticas. Conclusiones: La metodología propuesta resultó sencilla y rápida y permitió detectar el incremento de huellas en el área, estableciendo así valores de referencia para posteriores evaluaciones. El incremento de huellas observado, enfatiza la necesidad de priorizar la conservación y de incorporar nuevas capas temáticas para enriquecer la gestión del área protegida.

Uno de los temas recurrentes en la literatura argentina es la tensa relación del hombre con el desierto y sus leyes. Desde los primeros cronistas hasta los escritores románticos, la dialéctica del sujeto y el espacio fue abordada discursivamente por innumerables autores. Bajo esa perspectiva y deudor de esa tradición, César Aira irrumpe en la escena nacional con una de sus primeras obras para cuestionar y homenajear la tradición literaria decimonónica. El siguiente artículo analiza la novela Ema la cautiva (1981) en relación con los imaginarios de poder que deconstruyen la visión del desierto, los cautivos, los indios. Se intentará señalar los mecanismos de escritura utilizados por el autor para lograr mostrar una mirada novedosa e irreverente de la tradición literaria argentina del siglo XIX.

Las primeras palabras que dirige Jeremías a Israel, presentes en Jr 2, recogen importantes aspectos del libro del profeta de Anatot: alianza de Dios con su pueblo, rebeldía y rechazo de éste y consecuencias del mismo. Dentro del citado capítulo, Jr 2,1-19 forma una unidad, en la que Dios denuncia las infidelidades de Israel y rememora la perenne fidelidad que le mostró en el pasado. Así, Dios reprende a su pueblo por haberse alejado de él y haber caminado en dirección a otros dioses y le recuerda el tiempo dorado del desierto, lugar de muerte por antonomasia, en el que le hizo andar y caminar, satisfaciendo todas sus necesidades. La consideración de ambas acciones, la de Dios y la de Israel, dentro del marco de referencia en que se encuentran permite bosquejar una conclusión teológica y su consecuencia más lógica: a Dios lo puede encontrar Israel sin ponerse en movimiento, sin caminar en su búsqueda.

Background and aims: The transit of vehicles within protected areas constitutes a threat to the natural heritage that must be evaluated. The high operational cost of monitoring these activities makes it necessary to develop quick and simple evaluation alternatives that allow having a first parameter of trends. Using freeware and basic techniques, I propose a study case to evaluate the increase in vehicle traces for the period 2004-2018 and their potential impact on the vegetation of the Loma de Las Tapias protected area, San Juan, Argentina. M&M: Using pre-existing floristic zoning and two sets of satellite images (2004-2018), vehicle traces were quantified with a grid, and these squares were categorized according to: absence of traces; old traces (2004); new traces (2018) and relapsing traces (2004-2018) on the different floristic units. Results: Currently, from the 223 squares that constitute the grid, only 35% showed no vehicular traces, while 13.9% had only old ones, 30% relapsing traces and the remaining 21.1% had new vehicular traces. The increase during the evaluated period was uniform in all floristic units. Conclusions: The proposed methodology was simple and fast and allowed detecting the increase of vehicular traces in the area, establishing reference values for subsequent evaluations. The observed increase of traces emphasizes the need to focus on conservation efforts and to incorporate new thematic layers to enrich the management of the protected area. [ABSTRACT FROM AUTHOR]

During the evening of January 9th, 2020, an adult female of Sicarius thomisoides was found under a rock feeding on a gecko Phyllodactylus gerrhopygus. The observation was made at Mamiña, Tamarugal province in northern Chile. This find is the first documented case of a sicariid preying on a vertebrate. Specifically, this event corresponds to a particular case of intraguild predation, since these species are insectivorous and use similar microhabitats in northern Chile. [ABSTRACT FROM AUTHOR]

Solar radiation, winds and cover vegetation can affect nest construction decisions in birds; for example, the orientation of their entrance. In this study, the nest entrance orientation of rufous hornero (Furnarius rufus) in a subtropical desert site from Northern Argentina was examined. It was evaluated whether solar radiation and winds influence the mean orientation of nests with abundant upper vegetation cover and of those with little or no upper vegetation cover. Nests with abundant upper vegetation cover showed a randomly defined nest entrance orientation, suggesting that solar radiation and winds are not relevant in nest construction. Nests with little or no upper vegetation cover showed a non-random entrance, southeastern oriented, which would avoid direct solar radiation. Thus, nest with little or no upper vegetation cover were oriented towards prevailing southern humid winds as to increase cooling inside the nest. This work emphasizes the importance of including nest vegetation cover as a variable that may affect nest orientation. [ABSTRACT FROM AUTHOR]

The genus Liolaemus presents great diversity among the current tetrapods. It is the second genus with the highest number of valid species described of the Iguana infraorder. In this study, we described a new species of sand lizard from the coastal lomas of Quilca, La Chira and Ocoña that belongs to the subgenus Eulaemus and group of Liolaemus montanus, all in the province of Camaná, department of Arequipa, Peru. To determine the taxonomic status of this new organism, we analyzed morphological, molecular and geographical characters. The morphological characters allowed the characterization and diagnosis of the new species, the molecular data was used to make a Bayesian inference, and the geographic data served to determine potential distribution areas. This lizard diverges from the other species of the Liolaemus montanus group for its small to medium size, several sets of morphological characters, folidosis and color pattern. It is also the only species of the genus where the males have a pattern of lateral spots of rounded shape with dark border and green interior, from the armpits to the middle of the body. Additionally, the molecular phylogenetic results made with the Cyt-b gene indicate that it has no direct relationship with the phenetically similar species described for the group; nevertheless, there is a relationship with geographically close populations, which has not been properly described. Finally, it was determined that this lizard has a very marked endemism and its populations are not abundant. [ABSTRACT FROM AUTHOR]

Territorial representations have been fundamental for the formation of modern Nation-State. This article analyzes the ways some cartographic productions disseminated during the Argentine Nation-State formation and contributed to create hegemonic image of the country. More specifically, it studies the mechanisms by which those representations defined the Pampean-Patagonian region as a desert, that is to say, as a differentiated space of the nation. This work reflects on the process of unmarking Argentinian identity and marking indigenous otherness by considering the thesis in which the concept of desert in Argentina involves an historical and political way of asking about the social relationship with indigenous people. In this way, it seeks to contribute to the recognition and the historical contextualization of the Argentine space-temporal process of collective identification and control of sociocultural diversity.

Thylamys bruchi is a small and endemic marsupial from Argentina which inhabits the Monte Desert. It presents nocturnal and scansorial habits (i.e. uses terrestrial and arboreal strata) and its diet is omnivorous with a tendency to insectivory, regardless of the fluctuations in food's availability. The aim of this study was to evaluate the feeding strategy of T. bruchi seasonally, analyzing the selection of prey and the trophic niche breadth. Fieldwork was carried out at the Ñacuñan Man and Biosphere Reserve, Mendoza, during the wet and dry season of 2014 and 2016. This study focused on assessing the composition of arthropods in the diet. For this purpose, we measured prey consumption and their availability in the environment in the different seasons. T. bruchi's diet presented little seasonal variability, with 70% arthropods and 30% plant material. Eight orders and one family of arthropods were identified, with Lepidoptera being the most consumed ítem. T. bruchi selected Lepidoptera (adults and larvae) and Orthoptera in all seasons. Trophic niche breadth was greater in seasons with less prey availability and narrower when their abundance was greater. Although T. bruchi presents a generalist feeding strategy, in face of seasonal changes in prey abundance, it incorporates most of the available items and partially modifies the composition of its diet by exploiting more abundant items. This flexibility and the consumption of high energy food items such as arthropods may allow T. bruchi to survive in unfavorable and changing environments like deserts. [ABSTRACT FROM AUTHOR]

En los artículos publicados por D. F. Sarmiento en El Nacional a partir de 1855 y El tempe argentino (1858) de Marcos Sastre, la construcción del paisaje está habilitada por la consideración del Delta del Paraná Inferior como Desierto; una tabula rasa atemporal que permite hacer surgir la imaginación sobre el territorio y proyectar sobre este la configuración de un paisaje armónico con alto potencial productivo. En Apuntes sobre las islas del Delta argentino de Santiago Albarracín, la introducción de la contabilidad intenta desarticular la construcción del Delta como paraíso en la medida en que recupera un orden sucesivo para narrar los intentos de volver esta tierra productiva. Esta confrontación exhibe no solo un cuestionamiento sobre modos de representación, sino también un resquebrajamiento de una construcción armónica de paisaje basada en un orden natural, en la que la productividad es vista como una propiedad de la tierra antes que del trabajo humano.

“El desierto crece” afirma Nietzsche, pero ¿dónde está el desierto? Más allá de Chile o Argentina el paisaje de las arenas ha cobrado un sentido ético y filosófico negativo a instancias de la modernidad tardía. Öde (desierto) en alemán significa el vacío, la nada, el nihilismo. Sin embargo, tras las ruinas de la modernidad podemos encontrar otra posibilidad del desierto. Contraria a la tradición exegética se propone la desertificación ya no como metáfora del nihilismo sino, en cambio, como una configuración de lo posible tendiente a la vida, la esperanza y la escritura. El presente análisis pretende estudiar los procesos de desertificación en la poesía de Raúl Zurita y Hugo Mujica como clave para un recomenzar estético. Con la intervención poética en Atacama (“Ni pena ni miedo”, 1993), Zurita pone en diálogo el paisaje con la escritura de la memoria reciente en Chile. Por otra parte, el desierto presenta en la poética de Hugo Mujica la posibilidad del destierro, del eremita, que sólo allí, en las arenas del tiempo, encuentra el silencio. Por esta razón, en la poesía de Zurita y Mujica no es suficiente la imagen de un desierto como final, como ocaso o noche; es más bien un recomenzar desde las ruinas, un alba del desierto.

En este artículo se analizan los usos de la imagen del desierto en De itinere deserti de Ildefonso de Toledo, una obra breve, elaborada a mediados del siglo VII, en la que se destaca el ideal de austeridad y disciplina de los santos. A partir de la selección y combinación de elementos bíblicos y patrísticos, Ildefonso enfatiza la centralidad del desierto en una obra destinada a impartir instrucciones de salvación a todos los bautizados. En este marco, De itinere deserti invita a indagar los modos de construcción de la autoridad episcopal en el siglo VII en general y en el contexto toledano en particular.

El texto identifica y analiza estéticamente la presencia icónica y argumental recurrente del desierto en los filmes de Pier Paolo Pasolini. Como sitio de exposición del origen propio y de puesta a prueba de la integridad de lo humano, el desierto de Pasolini se propone como un lugar ontológico. En este análisis, la poesía y la prosa del artista italiano contribuyen a delimitar las formas y funciones estéticas del desierto en su poética cinematográfica.

Understanding and conserving mobile species presents complex challenges, especially for animals in stochastic or changing environments. Nomadic waterbirds must locate temporary water in arid biomes where rainfall is highly unpredictable in space and time. To achieve this they need to travel over vast spatial scales and time arrival to exploit pulses in food resources. How they achieve this is an enduring mystery. We investigated these challenges in the colonial-nesting Banded Stilt ( Cladorhynchus leucocephalus), a nomadic shorebird of conservation concern. Hitherto, Banded Stilts were hypothesized to have only 1-2 chances to breed during their long lifetime, when flooding rain fills desert salt lakes, triggering mass-hatching of brine shrimp. Over 6 years, we satellite tagged 57 individuals, conducted 21 aerial surveys to detect nesting colonies on 14 Australian desert salt lakes, and analyzed 3 decades of Landsat and MODIS satellite imagery to quantify salt-lake flood frequency and extent. Within days of distant inland rainfall, Banded Stilts flew 1,000-2,000 km to reach flooded salt lakes. On arrival, females laid over half their body weight in eggs. We detected nesting episodes across the species' range at 7 times the frequency reported during the previous 80 years. Nesting colonies of thousands formed following minor floods, yet most were subsequently abandoned when the water rapidly evaporated prior to egg hatching. Satellite imagery revealed twice as many flood events sufficient for breeding-colony initiation as recorded colonies, suggesting that nesting at remote sites has been underdetected. Individuals took risk on uncertain breeding opportunities by responding to frequent minor flood events between infrequent extensive flooding, exemplifying the extreme adaptability and trade-offs of species exploiting unstable environments. The conservation challenges of nest predation by overabundant native gulls and anthropogenic modifications to salt lakes filling frequencies require investigation, as do the physiological and navigational mechanisms that enable such extreme strategies.
