Microclimatic changes and the indirect loss of ant diversity in a tropical agroecosystem

Recent changes in the coffee agroecosystem of Costa Rica were used to study the mechanism of biodiversity loss in transforming agroecosystems, focusing on the ground-foraging ant community. Coffee farms are being transformed from vegetationally diverse shaded agroforestry systems to unshaded coffee monocultures. We tested the hypothesis that the high-light environment and lack of leaf litter cover in the unshaded system are the determinants of the differences in ground-foraging ant diversity. Four treatments were established within the light gaps of a shaded plantation: shade, leaf litter, shade plus leaf litter, and a control (no shade or leaf litter added). Ants were sampled using tuna fish baits and light and temperature were measured. Shade and leaf litter had a significant effect on the ant fauna but probably for indirect reasons having to do with species interactions. In both shade treatments, Solenopsis geminata , the tropical fire ant, decreased significantly while the other species increased. The possibility that the physical factor changes the nature of competitive interactions between the most abundant species is discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47696/1/442_2004_Article_BF00333736.pd

The Good, the Ugly and the Dirty Harry’s of Conservation: Rethinking the Anthropology of Conservation NGOs

For the past decade, narrative portrayals of non-governmental organisations (NGOs) growing big, 'ugly', and business-minded have become common in both social science and public discourse. At a time when both engagement within NGOs as well as critical analysis from the outside has blossomed, how are the social sciences and anthropology in particular responding? This article suggests that a set of meta-narratives characterise much of the literature analysing conservation NGOs. Such narratives respectively position NGOs as doing good, turning ugly or acting pragmatically through what I label 'Dirty Harry' characteristics. While the critique of conservation NGOs offers a much needed 'reality check', it is time to revisit dichotomies of the 'good' past and the ugly present. The article reviews trends in the literature and offers a case study from the Peruvian Amazon. The final synthesis emphasises the need for a less essentialist perspective tracing heterogeneity and change of NGO activity over time

The Non-human Borderlands: Engaging with ecological justice and indigenous rights in Amazonia

Indigenous rights’ relationship to ecological justice in Amazonia has not been explicitly explored in the literature. As social scientists rarely talk about violence against non-humans, this case study of conservation in Amazonia will explore this new area of concern. Ethical inquiries in conservation also engage with the manifold ways through which human and nonhuman lives are entangled and emplaced within wider ecological relationships, converging in the notion of environmental justice, which often fails to account for overt violence or exploitation of non-humans. Reflecting on this omission, this chapter discusses the applicability of engaged social science and conservation to habitat destruction in Amazonia, and broader contexts involving violence against non-humans. The questions addressed in this chapter are: is the idea of ecological justice sufficiently supported in conservation debate, and more practical Amazonian contexts? Can advocacy of inherent rights be applied to the case of non-humans? Can indigenous communities still be considered 'traditional' considering population growth and increased consumptive practices? Concluding that the existing forms of justice are inadequate in dealing with the massive scale of non-human abuse, this chapter provides directions for conservation that engage with deep ecology and ecological justice in the Amazonian context. doi: 10.1007/978-3-030-29153-2 LinkedIn: https://www.linkedin.com/in/helenkopnina
