Birth of the Marimacho: Modernismo's Trans* Cultural Productions in Latin America
<p><em>Birth of the Marimacho: Modernismo’s Trans* Cultural Productions in Latin America </em>is a Horizon Marie Skłodowska Curie Action 2022-funded project under grant number 101103095.<em> </em>This research analyzes the representations of a radical gender embodiment in early-twentieth-century Latin American literature, medical science, and visual culture: the ‹‹marimacho››. In the Hispanic tradition, <em>marimacho </em>is the umbrella notion that may refer to a sexist slur as much as a modern form of non-binary gender, a transmasculine identification, or a lesbian sexual identity. This project examines the aesthetic construction of this hybrid, counter-cultural, and gender-dissident figure in an extensive cultural repertoire that includes novels, plays, silver films, leaflets, medical studies, prison and mental hospital records, poems, newspaper, and tabloid articles from the period 1880-1930.</p> <p>Data collection aims to assemble a corpus of published and unpublished sources held in print and digital archives and special collections in Latin America and Europe. These sources are copyright-free and are available through open access in university digital repositories, national archives, and research institutes in Germany, France, Mexico, Spain, and Argentina. The main purpose of the data collected and presented in this critical reference data base is to analyze its content through the methodologies of literary studies and gender theory concerning the main research questions of the project outlined in the original proposal. Some of the research questions that inform this project are:</p> <p>1) What gendered formats, systems of racial classification, and mechanisms of sexual exclusion did modernista & avant-garde writers use to construct the <em>marimacho</em> (butch women/ early forms of transmasculinities/lesbian populations) but also the <em>maricón</em>(the fairy) as public enemies of national morals?</p> <p>2) How and why did writers engage with tropes of world literary traditions—notions of Greek love, vampirism, primitivism, orientalism, teratology, and sexual inversion— to define the <em>marimachos</em> and <em>maricones</em> as dangers to bourgeois society?</p> <p>3) What aesthetic practices such as clothing, hair, makeup, fashion, fragrance, tattooing, sports, dancing, poetics, and musical performances did queer women, non-binary peoples, and trans* men use to contest naturalized notions of femininity and masculinity?</p> <p>This research seeks to increase the understanding of the region’s politics of gender and sexuality during the so-called positivist era (1880-1930), that is, before the solidification of LGBTQ activism, pride literature, and minority social movements of the Global 1960s. In the period of modernization that this project covers, there was a reaction against new gender dynamics led by cosmopolitan networks of feminism and the discreet homosexual liberation movements of the turn of the century. In response, the keepers of gender normativity created the <em>marimacho</em> as a monster version of conventional masculinity. Today, examining this response of the late 19<sup>th</sup> and early 20<sup>th</sup> centuries is crucial to understand the current anti-LGBT hatred in socio-political discourse.</p> <p><strong> </strong></p> <p><strong> </strong></p> <p><strong> </strong></p>
Unique functional diversity during early Cenozoic mammal radiation of North America
<p>Mammals influence nearly all aspects of energy flow and habitat structure in modern terrestrial ecosystems. However, anthropogenic effects likely have altered mammalian community structure, raising the question of how past perturbations have done so. We use functional diversity to describe how the structure of North American mammal communities changes over the past 66 Ma, an interval spanning the rebound radiation following the K/Pg and several subsequent environmental disruptions including the PETM, the expansion of grassland, and the onset of Pleistocene glaciation. For 264 fossil communities, we examine three aspects of ecological function: functional evenness, functional richness, and functional divergence. Shifts in functional diversity are significantly related to major ecological and environmental transitions. All three measures of functional diversity increase immediately following the extinction of the non-avian dinosaurs, suggesting that high degrees of ecological disturbance can lead to synchronous responses both locally and continentally. Otherwise, the components of functional diversity respond differently to environmental changes and are decoupled for the last ~56 million years.</p>
Defoliator outbreaks track with warming across the Pacific coastal temperate rainforest of North America
<p>The biogeography of irruptive insect herbivores is determined by host availability and climate conditions. As such, outbreak distributions are sensitive to climatic change, especially across large latitudinal gradients. Here, we investigate the outbreak distributions of two understudied defoliators, hemlock sawfly (Hymenoptera; <em>Neodiprion tsugae</em>) and western blackheaded budworm (Lepidoptera; <em>Acleris gloverana</em>), that have both recently impacted the greatest land area recorded across the Pacific coastal temperate rainforest since the establishment of aerial survey programs. We compiled polygon-based estimates of insect damage collected by aerial observers, forest inventory, and downscaled climatic data to develop gridded estimates of bioclimatic conditions across the extent of the Pacific coastal temperate rainforest, including the continental United States, British Columbia, and Alaska. We leveraged these data to develop ensemble machine learning models with the goal of predicting the outbreak distribution of each insect. In this manuscript we: (1) describe the historical patterns of defoliator outbreaks, (2) identify and describe climatic conditions associated with outbreaks in both species, and (3) assess whether historic outbreaks have tracked geographic shifts in climate conditions across the region. We demonstrate that outbreaks of hemlock sawfly and western blackheaded budworm have been observed across the Pacific coastal temperature rainforests of North America in each decade since the establishment of the Canadian and United States aerial survey programs. The distribution of outbreaks by both insects were best explained by host availability, a limited range of spring, summer, and winter temperatures, and minimum precipitation. Finally, we demonstrate that outbreaks have tracked the poleward shift in suitable climate over the last century. This study establishes a baseline understanding of the climatic constraints and biogeographic patterns of historic sawfly and budworm outbreaks across the Pacific coastal temperate rainforest and emphasizes the overarching importance of climate in driving the irruptive dynamics of these defoliator species.</p>
