La pérdida de biodiversidad en la agricultura moderna ha traído como consecuencia el debilitamiento de los servicios ecosistémicos asociados y el aumento del uso de insumos químicos. La agroecología señala que es posible diseñar y manejar agroecosistemas sustentables que minimicen o eliminen el uso de insumos químicos. Uno de ellos es el control por enemigos naturales como, por ejemplo, a través de los murciélagos. Su presencia y actividad pueden tener un lugar importante en las estrategias en el fortalecimiento del Potencial de Regulación Biótica (PRB). El PRB puede definirse como la capacidad potencial de un agroecosistema para mantener reguladas las poblaciones de plagas a través de sus funciones ecológicas. En la provincia de Buenos Aires los murciélagos son exclusivamente insectívoros, y juegan un papel fundamental en áreas naturales como reguladores de las poblaciones de insectos. Evaluar la capacidad de un sistema para favorecer su presencia y actividad requiere del desarrollo de indicadores sencillos que puedan ser aplicados en fincas. Se construyeron indicadores basados en a) la estructura del sistema y b) el manejo de los productores; y se comprobó su utilidad en tres fincas ubicadas en la Pampa Ondulada (Buenos Aires). La diversidad y abundancia de los murciélagos capturados coincidieron con los valores de los indicadores, señalando que estos últimos resultan ser buenos estimadores de las condiciones necesarias para su presencia y actividad. Esto permite desarrollar estrategias de manejo que favorezcan a los murciélagos como controladores biológicos.

Conti: One of the main conclusions of the Wolf-Rayet symposium in Buenos Aires was that Wolf-Rayet stars are evolutionary products of massive objects. Some questions:–Do hot helium-rich stars, that are not Wolf-Rayet stars, exist?–What about the stability of helium rich stars of large mass? We know a helium rich star of ∼40 MO. Has the stability something to do with the wind?–Ring nebulae and bubbles : this seems to be a much more common phenomenon than we thought of some years age.–What is the origin of the subtypes? This is important to find a possible matching of scenarios to subtypes.

History Of

This paper interrogates the history of same-sex dancing among women in Buenos Aires' tango scene, focusing on its increasing visibility since 2005. Two overlapping communities of women are invoked. Queer tangueras are queer-identified female tango dancers and their allies who dance tango in a way that attempts to de-link tango's two roles from gender. Rebellious wallflowers are women who practice, teach, perform, and dance with other women in predominantly straight environments. It is argued that the growing acceptance of same-sex dancing in Argentina is due to the confluence of four developments: 1) the rise of tango commerce, 2) innovations of tango nuevo, 3) changing laws and social norms around lesbian, gay, bisexual, and transgender rights, and 4) synergy between queer tango dancers and heterosexual women who are frustrated by the limits of tango's gender matrix. The author advocates for increased alliances between rebellious wallflowers and queer tangueras, who are often segregated from each other in Buenos Aires' commercial tango industry.

Pablo Neruda's Transnational Modernist Networks: Colombo-Madrid-London-Buenos Aires (1927–1933)

Standing Question

This article positions Pablo Neruda's poetry collection Residence on Earth I (written between 1925–1931 and published in 1933) as a ‘text in transit’ that allows us to trace the development of transnational modernist networks through the text's protracted physical journey from British colonial Ceylon (now Sri Lanka) to Madrid, and from José Ortega y Gasset's Revista de Occidente (The Western Review) to T. S. Eliot's The Criterion. By mapping the text's diasporic movement, I seek to reinterpret its complex composition process as part of an anti-imperialist commitment that proposes a form of aesthetic solidarity with artistic modernism in Ceylon, on the one hand, and as a vehicle through which to interrogate the reception and categorisation of Latin American writers and their cultural institutions in a British periodical such as The Criterion, on the other. I conclude with an examination of Neruda's idiosyncratic Spanish translation of Joyce's Chamber Music, which was published in the Buenos Aires little magazine Poesía in 1933, positing that this translation exercise takes to further lengths his decolonising views by giving new momentum to the long-standing question of Hiberno-Latin American relations.

From the Tower of London to the Thomas More Society of Buenos Aires: “Give me thy grace, good Lord, to set the world at nought”

Almost All

The Thomas More Society of Buenos Aires begins or ends almost all its events by reciting in both English and Spanish a prayer written by More in the margins of his Book of Hours probably while he was a prisoner in the Tower of London. After a short history of what is called Thomas More’s Prayer Book, the author studies the prayer as a poem written in the form of a psalm according to the structure of Hebrew poetry, and looks at the poem’s content as a psalm of lament.
