This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The pupal cocoons of two southern African wild silkmoth species, Gonometa postica and G. rufobrunnea (Lepidoptera: Lasiocampidae), are composed of high quality silk and have potential as a commercially viable resource. However, limited ecological research has been done on these species, and their population dynamics is especially poorly known. A steady and predictable supply of cocoons is paramount to the economic sustainability of a wild silk industry. There is thus an urgent need for documenting and understanding the population dynamics of southern Africa's Gonometa species. Here, the temporal and spatial variation of pupal (and thus cocoon) abundance, as well as associated natural enemies, are described for both Gonometa species for the first time. The larval parasitoid species emerging from parasitised pupae were quantitatively associated with species-specific emergence holes, making field-identification of these species possible. Eleven sites in total were sampled, over four generations, across the region where both species have historically reached high population densities. Apparent spatial synchrony in pupal abundance found between sites suggests that climate is responsible for observed population size fluctuations. As predicted from their life history traits, temporal variability was lower than expected for classically eruptive species. Gonometa species thus have an intermediate position on the population dynamics gradient. In turn, the responses of natural enemies were not predictable from Gonometa species defensive traits, but appear to be mediated by between-species cocoon strength differences. Using data on the number of G. postica pupae per tree and associated parasitism at several sites, the importance of the degree of spatial explicitness in the quantification of aggregation and the detection of density dependence was illustrated. The spatially explicit method gave different results and more information regarding the spatial pattern of pupal abundance and parasitism than non- and semi-explicit methods. Similarly, the detection of density dependence in parasitism rates was affected by the use of spatially explicit data, with the spatial explicit approach giving different and more biologically informative results than traditional, non-spatially explicit methods. This has marked implications for previous insect-host - parasitoid studies aimed at detecting density dependence. The variability in cocoon size, a surrogate for larval performance, adult fecundity and silk yield, revealed that gender, followed by species, contributed most to observed size differences, with no clear differences between generations or localities. Finally, the between-host plant and withinhost plant distribution ofG. postica and G. rufobrunnea pupae was quantified, chiefly investigating the deterministic nature of the choice of pupation site. The distribution of both species at these scales was found to be markedly non-random, with pupae generally preferring specific tree characteristics and micro-sites. These results now provide the basis for recommending an appropriate utilisation strategy for southern Africa's wild silk moths. Based on the spatial and temporal variability in pupal abundance observed, a constant and predictable cocoon supply for natural harvesting is unlikely. Long-term, broad-scale documentation of Gonometa species population cycles may make it possible to predict cocoon availability in the future. Until such research is done, it is recommended that the current practise of only collecting cocoons from which moths have emerged be continued. Simultaneously, artificial rearing and seeding as alternative utilisation strategies should be experimentally explored based on the information gathered and patterns identified here.

Available in PDF, EPUB and Kindle. Book excerpt: Materials play a central role in society. Beyond the physical and chemical properties of materials, their cultural properties have often been overlooked in anthropological studies: finished products have been perceived as ‘social’ yet the materials which comprise them are considered ‘raw’ or natural’. The Social Life of Materials proposes a new perspective in this interdisciplinary field. Diverting attention from the consumption of objects, the book looks towards the properties of materials and how these exist through many transformations in a variety of cultural contexts.Human societies have always worked with materials. However, the customs and traditions surrounding this differ according to the place, the time and the material itself. Whether or not the material is man-made, materials are defined by social intervention. Today, these constitute one of the most exciting areas of global scientific research and innovation, harboring the potential to act as key vehicles of change in the world. But this ‘materials revolution’ has complex social implications. Smart materials are designed to anticipate our actions and needs, yet we are increasingly unable to apprehend the composite materials which comprise new products.Bringing together ethnographic studies of cultures from around the world, this collection explores the significance of materials by moving beyond questions of what may be created from them. Instead, the text argues that the materials themselves represent a shifting ground around which relationships, identities and powers are constantly formed and dissolved in the act of making and remaking.

Book Synopsis The Material Subject by : Urmila Mohan
Download or read book The Material Subject written by Urmila Mohan and published by Routledge. This book was released on 2020-11-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Material Subject emphasises how bodily and material cultures combine to make and transform subjects dynamically. The book is based on the French Matière à Penser (MaP) school of thought, which draws upon the ideas of Mauss, Schilder, Foucault and Bourdieu, among others, to enhance the anthropological study of embodiment, practices, techniques, materiality and power. Through theoretical sophistication and empirical field research, case studies from Europe, Africa and Asia bring MaP’s ideas into dialogue with other strands of material culture studies in the English-speaking world. These studies mediate different scales of engagement through a sensori-motor, affective and cognitive focus on practices of making and doing. Examples range from the precarity of professional divers in French public works to the gendered subjectivity of female carpet weavers in Morocco, from the ways Swiss watchmakers transmit craft knowledge to how Hindu devotees in India make efficacious use of altars, and from the enskilment of Paiwan indigenous people in Taiwan to the prestige of women’s wild silk wrappers in Burkina Faso. The chapters are organised according to domains of practice, defined as 'matter of' work and technology, heritage, politics, religion and knowledge. Scholars and students with an interest in material culture will gain valuable access to global research, rooted in a specific intellectual tradition.
