    The 12,000 kilometers of international boundaries within the Amazon’s lowland rainforest biome form the axis of a borderland region shared by the nine states of Amazonia (Figure 1). These Amazon borderlands contain high concentrations of conservation units and indigenous territories to preserve the transboundary region’s rich ecological and cultural diversity (Figures 2 & 3). However, this biocultural diversity is increasingly threatened by advancing development frontiers and a growing global demand for Amazonian resources.https://scholarship.richmond.edu/geography-posters/1004/thumbnail.jp

    Gender and Species Use in Amazonian Home Gardens: the Social and Economic Context of Biodiversity Conservation

    Home gardens, “the peridomestic area belonging to the household where members plant and/or tend useful plants” (Perrault-Archambault and Coomes 2008), are found throughout the world. However, their use and importance vary from region to region. In the Peruvian Amazon, owners use home gardens for a domestic supply of foods, craft materials, medicines, condiments, and shade (Miller and Nair 2006). With this wide range in function, reflected in species content, home gardens are very biodiverse. Home garden biodiversity may be increasingly important in a rapidly changing Amazonia (Betts et al. 2008). Thus, the sociocultural and economic factors contributing to home garden diversity warrant in-depth study. Existing data posit a direct positive relationship between female garden tenders and species diversity (Perrault-Archambault and Coomes 2008) as well as report a simultaneous increase in sales of indigenous plant products and monocropping (Perreault2005). Nevertheless, limited research exists on home gardens as reservoirs for species conservation (Ban and Coomes2004b). We hypothesize both the gender of the caretaker and market integration impact levels of species richness in home gardens, with female garden managers increasing biodiversity and market integration decreasing biodiversity as caretakers favor more marketable species.https://scholarship.richmond.edu/geography-posters/1005/thumbnail.jp

    Amazonian States Map Threatened Borderlands

    Recently, the Regional Initiative to Integrate South America has begun promoting a transboundary road that would bisect the forested borderlands and connect the two largest cities in the region, while the state governments seek to promote a direct ecological railroad alternative. Both transportation initiatives promise to alter forests and rivers and transform economies and cultures, but these projects also lack the base geographic information necessary to understand their potential transboundary impacts and benefits

    La Amazonia peruana esta clasificada como un ecosistema mega-diverso. La riqueza de especies de fauna y flora acrecienta la diversidad de la población humana. La cuenca del río Abujao está poblada por mestizos y grupos indígenas Ashéninka y Shipibo-Conibo, los cuales todavía guardan parte de sus tradiciones, conocimientos ancestrales y ecológicos. Esta investigación se realizó con la finalidad de conocer el uso de especies de mamíferos y aves silvestres, por la población indígena y mestiza en la cuenca del río Abujao. Se determinaron categorías de uso; entre las categorías determinadas predomina el mayor conocimiento de mamíferos y aves silvestres para el uso alimenticio, medicinal y comercial; relativamente pocas especies y parte de estas son para uso ritual, mágico y ornamental debido a la pérdida de conocimientos y tradiciones ancestrales. Rescatando estos conocimientos el presente trabajo tiene una gran importancia en la conservación de aves y mamíferos y el conocimiento ecológico de la Amazonía Peruana.The Peruvian Amazon is classified as one of the mega-diverse ecosystem of the world. Local populations have benefited from the uses of its richness of fauna and flora, promoting the emergence of a wide variety of uses. The Abujao river basin, located in the Peruvian Amazon, is home for mestizos and indigenous groups of Ashéninka and Shipibo-Conibo, whose traditions, and ancestral and ecological knowledge are still alive and closely related to their natural environments. This research was carried out to determine how and to what extent present groups of indigenous and mestizo in the Abujao river basin have been using the wild species of mammals and birds in their locations. Categories of its uses were determined. Among of all defined categories, the most predominant one was the use of wild animals for human consumption, traditional medicine and commercial trades. In contrast, relatively few species, in whole or part, were still used for rituals, and ornamental due to the loss of some ancestral knowledge and traditions on these uses. Revaluing this set of knowledge and uses has a great importance in the conservation of birds and mammals as well as the ecological knowledge of local populations in the Peruvian Amazon

    Invisible Occupation: Indigenous Natural Resource Management in the Peruvian Amazon

    Get PDF
    On June 5th 2009, an estimated thirty people died in a clash between governmental authorities and indigenous people near Bagua, Peru. Termed the Bagua Massacre, this event underscores the marginalized role of Indigenous Amazonians when confronting multinational commercial interests supported by the state (Shepard, 2009). The indigenous people were protesting the “Law of the Jungle,” Decree 1090, a 2009 decree assuming heavily-forested indigenous lands idle and unproductive, and providing the legal basis to privatize comunally-held forests to facilitate petroleum, biofuel, hydroelectric and logging projects. Since contact, the assumption of indigenous people unproductively managing their forested homelands has fueled colonization, deforestation, and the displacement of indigenous residents. Our research uses Global Positioning System receivers (GPS) and a Geographic Information System (GIS) to provide a snapshot of indigenous management of natural resources not only in their readily visible agricultural fields, but also beneath the forest canopy and within lakes and river courses.https://scholarship.richmond.edu/geography-posters/1007/thumbnail.jp

    Staging Parkinson’s Disease According to the MNCD (Motor/Non-motor/Cognition/Dependency) Classification Correlates with Disease Severity and Quality of Life

    Background: Recently, a novel simple classification called MNCD, based on 4 axes (Motor; Non-motor; Cognition; Dependency) and 5 stages, has been proposed to classify Parkinson's disease (PD). Objective: Our aim was to apply the MNCD classification in a cohort of PD patients for the first time and also to analyze the correlation with quality of life (QoL) and disease severity. Methods: Data from the baseline visit of PD patients recruited from 35 centers in Spain from the COPPADIS cohort from January 2016 to November 2017 were used to apply the MNCD classification. Three instruments were used to assess QoL: 1) the 39-item Parkinson's disease Questionnaire [PDQ-39]); PQ-10; the EUROHIS-QOL 8-item index (EUROHIS-QOL8). Results: Four hundred and thirty-nine PD patients (62.05 +/- 7.84 years old; 59% males) were included. MNCD stage was: stage 1, 8.4% (N = 37); stage 2, 62% (N = 272); stage 3, 28.2% (N = 124); stage 4-5, 1.4% (N = 6). A more advanced MNCD stage was associated with a higher score on the PDQ39SI (p < 0.0001) and a lower score on the PQ-10 (p < 0.0001) and EUROHIS-QOL8 (p < 0.0001). In many other aspects of the disease, such as disease duration, levodopa equivalent daily dose, motor symptoms, non-motor symptoms, and autonomy for activities of daily living, an association between the stage and severity was observed, with data indicating a progressive worsening related to disease progression throughout the proposed stages. Conclusion: Staging PD according to the MNCD classification correlated with QoL and disease severity. The MNCD could be a proper tool to monitor the progression of PD
