Hydrobiomorpha iguazu Bachmann 1988
A new species of water beetle, Hydrobiomorpha iguazu, has been described from Iguazú National Park in Argentina. This discovery highlights the unique morphological traits of the species, including its large size (21.0–22.6 mm) and distinctive features such as a subelliptical body shape, a moderately long prosternal keel, and robust meso- and metatarsal claws with conspicuous proximal teeth. The male genitalia exhibit strong sclerotization with a bifurcate apex and elongate accessory appendages, while the female's fifth abdominal ventrite has a large subtriangular glabrous area. The species is further distinguished by its short setigerous furrow on the mesotibiae of males, unlike related species. The study utilized morphological analysis and examination of type specimens to characterize this new taxon, contributing to the biodiversity documentation of UNESCO World Heritage Sites.
Territorial expansion and parasitic zoonoses: the pampas gray fox in Argentina as a case study and its educational potential for prevention
Urban expansion into natural habitats increases the risk of zoonotic disease transmission, particularly through interactions with the Pampas gray fox (Lycalopex gymnocercus), a widespread and ecologically significant wild canid in Argentina. The study highlights that habitat fragmentation, land-use changes, and human encroachment facilitate closer contact between humans and native wildlife, creating conditions for pathogen exposure. Research demonstrates that Pampas gray foxes harbor multiple helminths and protozoa, including Neospora caninum, which poses economic risks to livestock and potential public health threats. The study emphasizes the need for One Health education to prevent zoonotic transmission, advocating for integrated approaches that address human-animal interactions in rural, peri-urban, and urban settings while promoting conservation through policy changes like banning poisons and improving waste management.

By synthesizing these diverse studies, the essay underscores the need for a multidisciplinary approach to address the challenges of sustainable development in Latin America.
Frederico Freitas. Nationalizing Nature: Iguazu Falls and National Parks at the Brazil-Argentina Border.
Iguazu National Park, straddling the Brazil-Argentina border, protects one of the world's most iconic natural wonders: Iguazu Falls and a critical remnant of the Atlantic forest. Frederico Freitas' study reveals that these binational parks serve as a lens to understand the complex interplay between nature conservation, economic development, and geopolitical relationships in the region. Through meticulous comparative historical analysis, Freitas demonstrates how the parks have evolved from the 1930s to the present day, reflecting broader transformations in the Atlantic forest—once vast but now reduced to less than 10% of its original extent. The study highlights the unexpected role of these parks in shaping borderland dynamics and conservation narratives.
Detecting Deforestation Using Logistic Analysis and Sentinel-1 Multitemporal Backscatter Data
A novel method using Sentinel-1 C-band backscattering data reveals that deforestation events can be accurately detected and dated in tropical forests, such as Iguazu National Park, with an F1-score of 0.93. This approach models temporal variability in backscatter intensity using a logistic function, identifying the inflection point as the deforestation date. While effective for tropical biomes, accuracy may drop by up to 20 percentage points in temperate forests due to environmental factors like rainfall and snow. The study demonstrates the potential of Sentinel C-band data for large-scale deforestation monitoring, with a slight delay of two months in estimating event dates.
Nationalizing Nature: Iguazu Falls and National Parks at the Brazil-Argentina Border
Frederico Freitas's 'Nationalizing Nature' reveals that the creation of Iguazu Falls National Parks in Brazil and Argentina during the 1930s was driven by nationalist motives to populate a contested borderland, rather than solely for conservation. This study demonstrates how these parks, later recognized as UNESCO World Heritage Sites, successfully preserved one of the last large tracts of Atlantic Forest against extensive deforestation. Freitas's research, based on extensive archival sources and interviews with key figures, challenges conventional narratives about national park origins by highlighting their role in borderland development and later reorientation toward environmental preservation. The study also notes that depopulation efforts in these parks primarily affected recent immigrants rather than Indigenous communities, offering a nuanced perspective on the cultural construction of wilderness areas.
Beyond the “Yellowstone Model:” The Origins of National Parks in Brazil and Argentina
National parks in Brazil and Argentina emerged not as isolated conservation efforts but as products of complex interactions between conservation goals and colonial legacies. Unlike the 'Yellowstone Model,' which prioritized pristine wilderness, these parks reflected local political, social, and ecological dynamics. Kaltmeier and Freitas analyze how Iguazu National Park, straddling the Brazil-Argentina border, exemplifies this entangled history, blending indigenous land use, scientific conservation, and geopolitical interests. Their review synthesizes two books—Kaltmeier's National Parks from North to South and Freitas' Nationalizing Nature—revealing how colonial narratives shaped modern conservation practices in the region.
Description of a new species ofAuriculostoma(Digenea: Allocreadiidae) fromCharacidium heirmostigmata(Characiformes: Crenuchidae) from Argentina, using morphological and molecular data
Researchers have identified a new species of digenean flatworm, Auriculostoma guacurarii, parasitic in the intestine of Characidium heirmostigmata fish within Iguazu National Park, Argentina. This discovery is based on unique morphological traits and phylogenetic analysis, distinguishing it from four congeneric species through differences in egg size, body length, genital pore position, sucker size, and post-testicular space. The study also sequenced the partial 28S rRNA gene of a related specimen, Auriculostoma cf. stenopteri, revealing its close genetic relationship with A. guacurarii and A. tica. This is the first species in the genus to parasitize a member of the Crenuchidae family, marking it as the tenth described species within this group.
Epilogue: The Resilience of Boundaries
Despite international advocacy for integrated management, the Iguazú and Iguaçu National Parks in Argentina and Brazil have remained distinct, with national sovereignty and transboundary tensions shaping their governance. This study reveals that park officials in both countries resisted calls from UNESCO for co-management and greater integration, perpetuating separate administrative frameworks. The analysis demonstrates how historical narratives of nationalism and boundary disputes persist even within shared natural landscapes, preventing the realization of 'peace parks'—a model of integrated transboundary conservation. By examining official discourse and policy documents from the 1980s onward, the research highlights the resilience of national boundaries in environmental governance.
Introduction: Boundaries of Nature
This study challenges conventional historical narratives by shifting the focus of Atlantic forest destruction from Brazil's coast to its borderlands, particularly within Iguazú and Iguaçu National Parks. It argues that these parks, established in the 1930s as tools for nationalizing border areas, are central to understanding the shared history of deforestation involving Argentina, Brazil, and Paraguay. The research compares the two parks to other American national park models, analyzing their role in border creation and conservation while situating them within recent literature on borders. By reorienting the geographical center of this historical process, it underscores the interconnectedness of environmental degradation across these nations.
Nationalizing Nature
National parks in Latin America, including Iguazu National Park straddling the Brazil-Argentina border, have served as pivotal tools for territorial development and national identity. A study reveals that these protected areas were initially created in the 1930s to attract migrants from densely populated coastal regions to sparsely inhabited borderlands, effectively 'nationalizing' these lands. However, this approach shifted dramatically in the 1970s under military regimes, which violently evicted settlers, exposing the complex interplay between authoritarianism and conservation efforts. By analyzing nearly a century of national park history in Brazil and Argentina, the research demonstrates how conservation policies were intertwined with broader national programs aimed at frontier development and border control.
Playing Catch-Up
The establishment of Iguazu National Park in Brazil in 1939 was driven by local political activism, which leveraged the creation of a neighboring park in Argentina. This study reveals that territorial development is not solely a top-down process but involves significant collaboration between local actors and national authorities. The research examines how state governors and local politicians pushed for the park's establishment as part of Brazil's 'March to the West' campaign during the 1940s, highlighting the role of intermediary agents in shaping national policies. By analyzing historical records and political dialogues, the study underscores the dynamic interplay between local advocacy and federal decision-making in the formation of protected areas.
