Introduction to "In Focus: Global Change and Adaptation in Local Places"

ABSTRACT   In recognition of unavoidable changes that human actions are producing in our environment, the term adaptation has become ubiquitous in the environmental and climate-change literature. Human adaptation is a field with a significant history in anthropology, yet anthropological contributions to the burgeoning field of climate change remain limited. This "In Focus" section presents studies of local adaptations to climate variation and change. Each is concerned with current environmental challenges and future environmental change, and each study is placed within a wider context that includes processes of globalization and integration into market economies, formal and informal institutions, and disasters. These studies highlight the challenges involved in understanding complex adaptations under conditions of stress. They also illustrate how anthropologists engage the larger climate-change and human-adaptation discussions and enhance our ability to respond to the challenges of a changing environment.     

Introduction to "Anthropology and Human Rights in a New Key"

In this "In Focus" introduction, I begin by offering an overview of anthropology's engagements with human rights following the American Anthropological Association's (AAA) 1947 "Statement on Human Rights." After offering a rereading of the Statement, I describe the two major anthropological orientations to human rights that emerged in the 1980s and 1990s, following several decades of relative disengagement. Finally, I locate the articles in relation to this history and indicate how, when taken as a whole, they express a new key or register within which human rights can be studied, critiqued, and advanced through anthropological forms of knowledge. This "In Focus" is in part an argument for an essentially ecumenical anthropology of human rights, one that can tolerate, and indeed encourage, approaches that are both fundamentally critical of contemporary human rights regimes and politically or ethically committed to these same regimes.     

Introduction to "Moral Economies, State Spaces, and Categorical Violence"

By studying and writing about social revolutions and popular protest, James Scott has provided anthropologists and social theorists with a wide-ranging analytical vocabulary for speaking about peace and its inseparable twin—violence. His particular area of expertise has been the arts of repressive peace, and the artfulness of those who elude or defy such silencing technologies. The publication of The Moral Economy of the Peasant in 1976 initiated the first interactions between Scott's unique brand of political theory and anthropology in the shared topical space of peasant studies and the shared geographic space of Asian studies. The authors of this "In Focus" have assembled this special collection to celebrate and evaluate those and subsequent interactions covering a quarter of a century and spanning the publication of at least three other books: Weapons of the Weak (1985), Domination and the Arts of Resistance (1990), and Seeing Like a State (1998).     

On Nanognathia,a New Gnathostomulid Genus from the East Coast of the United States

In continuation of a series of papers describing new representatives of the phylum Gnathostomulida from the east coast of North America, the monotypic genus Nanognathia is presented. It is distinguished by small size, grouped epidermal inclusions on the ventral body surface, and flattened basket-type jaws with long teeth of which one is developed as a terminal tooth. Together with the structure of the reproductive system, these characteristics place Nanognathia within the suborder Scleroperalia, family Onychognathiidae.     

Afterword to "Anthropology and Human Rights in a New Key": The Social Life of Human Rights

In this article, I argue for an ethnographic approach to human rights that recognizes the plural and fragmentary nature of the international rights regime and the ideological promiscuity of rights talk. Instead of determining in advance the social or political character of rights, anthropologists could profitably draw from the insights of early-20th-century "legal realists" and look closely at the underlying assumptions and hidden practices of political and legal processes. Studying the "social life of human rights" would involve focusing on, inter alia, the performative dimensions of human rights, the dynamics of social mobilization, and the attitudinal changes of elite and nonelite social actors towards formulations of "rights" and "justice," both inside and outside the legal process. I conclude with a review of recent anthropological research on human rights epistemology and evaluate its implications for human rights policy.     

Culture change and epidemiological patterns among the Hagahai,Papua New Guinea

The role of introduced epidemic disease in highland New Guinea is considered in light of recent debate concerning pre-contact adaptations. Seroepidemiological studies of the Hagahai, a small isolated group of hunterhorticulturalists in the fringe highlands of Papua New Guinea, document the recent introduction of mumps, hepatitis B, specific types of influenza, and rotavirus. Results are related to ethnographic findings, detailing past levels of intergroup contact and recent changes in settlement patterns, travel, feasting, health care, and other cultural factors. Data suggest that intergroup disease transmission is greatly increased decades before officially recorded time of contact and that mortality levels documented soon thereafter are not indicative of the pre-contact adaptation.     

The Potential Impact of Agricultural Management and Climate Change on Soil Organic Carbon of the North Central Region of the United States

Soil organic carbon (SOC) represents a significant pool of carbon within the biosphere. Climatic shifts in temperature and precipitation have a major influence on the decomposition and amount of SOC stored within an ecosystem. We have linked net primary production algorithms, which include the impact of enhanced atmospheric CO₂ on plant growth, to the Soil Organic Carbon Resources And Transformations in EcoSystems (SOCRATES) model to develop a SOC map for the North Central Region of the United States between the years 1850 and 2100 in response to agricultural activity and climate conditions generated by the CSIRO Mk2 Global Circulation Model (GCM) and based on the Intergovernmental Panel for Climate Change (IPCC) IS92a emission scenario. We estimate that the current day (1990) stocks of SOC in the top 10 cm of the North Central Region to be 4692 Mt, and 8090 Mt in the top 20 cm of soil. This is 19% lower than the pre-settlement steady state value predicted by the SOCRATES model. By the year 2100, with temperature and precipitation increasing across the North Central Region by an average of 3.9°C and 8.1 cm, respectively, SOCRATES predicts SOC stores of the North Central Region to decline by 11.5 and 2% (in relation to 1990 values) for conventional and conservation tillage scenarios, respectively.     

Estimates of Disease Effects on Soybean Yields in the United States 2003 to 2005

Research must focus on management of diseases that cause extensive losses, especially when funds for research are limited. Knowledge of the losses caused by various soybean diseases is essential when prioritizing research budgets. The objective of this project was to compile estimates of soybean yields suppressed due to diseases for each soybean-producing state in the US from 2003 to 2005. The goal was to provide this information to help funding agencies and scientists prioritize research objectives and budgets. Yield suppression due to individual diseases varied among regions in the US, and the total of soybean yields suppressed due to diseases in the US varied among years. Soybean cyst nematode suppressed US soybean yield more during 2003 to 2005 than any other disease. Phytophthora root and stem rot, sudden death syndrome, and seedling diseases ranked in the top four on the list of diseases that suppressed soybean yield during these years. This is the first report of soybean yield suppression due to Asian soybean rust in the United States.     

The Contribution of Mangrove Expansion to Salt Marsh Loss on the Texas Gulf Coast

Landscape-level shifts in plant species distribution and abundance can fundamentally change the ecology of an ecosystem. Such shifts are occurring within mangrove-marsh ecotones, where over the last few decades, relatively mild winters have led to mangrove expansion into areas previously occupied by salt marsh plants. On the Texas (USA) coast of the western Gulf of Mexico, most cases of mangrove expansion have been documented within specific bays or watersheds. Based on this body of relatively small-scale work and broader global patterns of mangrove expansion, we hypothesized that there has been a recent regional-level displacement of salt marshes by mangroves. We classified Landsat-5 Thematic Mapper images using artificial neural networks to quantify black mangrove (Avicennia germinans) expansion and salt marsh (Spartina alterniflora and other grass and forb species) loss over 20 years across the entire Texas coast. Between 1990 and 2010, mangrove area grew by 16.1 km², a 74% increase. Concurrently, salt marsh area decreased by 77.8 km², a 24% net loss. Only 6% of that loss was attributable to mangrove expansion; most salt marsh was lost due to conversion to tidal flats or water, likely a result of relative sea level rise. Our research confirmed that mangroves are expanding and, in some instances, displacing salt marshes at certain locations. However, this shift is not widespread when analyzed at a larger, regional level. Rather, local, relative sea level rise was indirectly implicated as another important driver causing regional-level salt marsh loss. Climate change is expected to accelerate both sea level rise and mangrove expansion; these mechanisms are likely to interact synergistically and contribute to salt marsh loss.     

Influence of hurricanes on coastal ecosystems along the northern Gulf of Mexico

Available literature indicates that hurricanes do not generally produce long-term detrimental impacts to unmodified coastal systems and that they often provide net benefits along the U.S. Gulf Coast. While there is normally initial erosion from hurricanes, they also often result in a large influx of inorganic sediments, creating new wetlands and contributing to the maintenance of existing wetlands. The formation of washover deposits is disastrous where cultural development has occurred, but in natural areas these deposits are part of the natural cycle of shoreline development and contribute to habitat diversity and productivity. Abundant rainfall typically associated with hurricanes often results in large increases of sediment and nutrient inputs into coastal estuaries, leading to both short-term and long-term increases in productivity. Rainfall during tropical disturbances accounts for a significant part of total precipitation along the northern gulf. The immediate impact of hurricanes may be to reduce populations of some species but these populations generally recover rapidly. Overall, productivity in natural systems seems to be increased by periodic hurricanes. Hurricane impacts are often severe and long lasting in wetlands that have been modified by human impacts such as semi- or complete impoundments.     

Sea-level rise and drought interactions accelerate forest decline on the Gulf Coast of Florida, USA

Sea-level rise threatens low-lying coastal ecosystems globally. In Florida, USA, salinity stress due to increased tidal flooding contributes to the dramatic and well documented decline of species-rich coastal forest areas along the Gulf of Mexico. Here, we present the results of a study of coastal forest stand dynamics in thirteen 400 m² plots representing an elevation gradient of 0.58–1.1 m affected by tidal flooding and rising sea levels. We extended previously published data from 1992–2000 to 2005 to quantify the full magnitude of the 1998–2002 La Niña-associated drought. Populations of the dominant tree species, Sabal palmetto (cabbage palm), declined more rapidly during 2000–2005 than predicted from linear regressions based on the 1992–2000 data. Dramatic increases in Juniperus virginiana (Southern red cedar) and S. palmetto mortality during 2000–2005 as compared with 1995–2000 are apparently due to the combined effects of a major drought and ongoing sea-level rise. Additionally, coastal forest stands continued to decline in species richness with increased tidal flooding frequency and decreasing elevation. Stable isotope (H, O) analyses demonstrate that J. virginiana accesses fresher water sources more than S. palmetto . Carbon isotopes reveal increasing δ ¹³C enrichment of S. palmetto and J. virginiana with increased tidal flooding and decreased elevation, demonstrating increasing water stress in both species. Coastal forests with frequent tidal flooding are unable to support species-rich forests or support regeneration of the most salt-tolerant tree species over time. Given that rates of sea-level rise are predicted to increase and periodic droughts are expected to intensify in the future due to global climate change, coastal forest communities are in jeopardy if their inland retreat is restricted.     

Production of goniodomin A by the planktonic, chain-forming dinoflagellate Alexandrium monilatum (Howell) Balech isolated from the Gulf Coast of the United States

The chain-forming dinoflagellate Alexandrium monilatum has been reported to be associated with widespread discolored water and increased fish mortality in the Mississippi Sound and off the eastern and western coasts of Florida. Previous studies over the last 60–70 years have determined that A. monilatum produces a harmful substance(s) that is predominantly contained in the cell mass as exhibited by apparent increased toxicity when the organism cytolyses. The current research in our lab corroborated earlier research demonstrating that A. monilatum produces a lipophilic toxin, unlike its Alexandrium relatives noted for their production of saxitoxin-like toxins. Using sophisticated chemical, chromatographic, and analytical techniques, we have successfully purified and identified the molecular structure of the toxin produced by A. monilatum. We utilized a 500 MHz NMR to carry out a number of experiments (i.e., ¹H, ¹³C, COSY, HSQC, and HMBC) to unambiguously determine the molecular structure of the toxin. In addition, we report mass analysis of the toxin utilizing electrospray ionization-mass spectrometry (ESI-MS), matrix-assisted laser desorption ionization-time of flight-mass spectrometry (MALDI-TOF-MS), and Q-TOF mass spectral techniques. The toxin is representative of a polyether macrolide with an empirical formula of C₄₃H₆₀O₁₂. This toxic compound is shown to be identical to a Japanese tidepool toxin identified as goniodomin A, which is produced by another Alexandrium species.     

Unmanaged Care: The Need to Regulate New Reproductive Technologies in the United States

In the aftermath of allegations of the misuse of human eggs in the United States, questions are being raised about whether profitable reproductive services should continue to function in a free market under the aegis of physicians or should be regulated. Other countries in which reproductive technologies are employed to a significant degree have developed regulations governing their use, many as a result of recommendations made by inter-disciplinary commissions that solicited public input. Policy makers in the United States have been reluctant to regulate reproductive technologies, however, because their use is politically controversial, they want to whittle down government, some do not consider infertility an illness, and some believe regulation would interfere with the right to reproduce. Yet the unfettered use of reproductive technologies can create such harms as lack of informed consent, providing procedures not medically indicated for financial gain, practice by unqualified personnel, injury to patients and donors, failure to screen donated gametes, and inadequate medical record keeping. Americans place special value on the welfare of children and those who bring them into the world. Such values can outweigh individual procreative liberty when new reproductive technologies are at issue. Although the optimal course would be to establish a regulatory body to govern reproductive technologies, this is not politically feasible now. The newly established National Bioethics Advisory Commission provides a forum in which issues surrounding reproductive technologies should be addressed at this time in the United States.     

Population Structure of Clinical and Environmental Vibrio parahaemolyticus from the Pacific Northwest Coast of the United States

Vibrio parahaemolyticus is a common marine bacterium and a leading cause of seafood-borne bacterial gastroenteritis worldwide. Although this bacterium has been the subject of much research, the population structure of cold-water populations remains largely undescribed. We present a broad phylogenetic analysis of clinical and environmental V. parahaemolyticus originating largely from the Pacific Northwest coast of the United States. Repetitive extragenic palindromic PCR (REP-PCR) separated 167 isolates into 39 groups and subsequent multilocus sequence typing (MLST) separated a subset of 77 isolates into 24 sequence types. The Pacific Northwest population exhibited a semi-clonal structure attributed to an environmental clade (ST3, N = 17 isolates) clonally related to the pandemic O3:K6 complex and a clinical clade (ST36, N = 20 isolates) genetically related to a regionally endemic O4:K12 complex. Further, the identification of at least five additional clinical sequence types (i.e., ST43, 50, 65, 135 and 417) demonstrates that V. parahaemolyticus gastroenteritis in the Pacific Northwest is polyphyletic in nature. Recombination was evident as a significant source of genetic diversity and in particular, the recA and dtdS alleles showed strong support for frequent recombination. Although pandemic-related illnesses were not documented during the study, the environmental occurrence of the pandemic clone may present a significant threat to human health and warrants continued monitoring. It is evident that V. parahaemolyticus population structure in the Pacific Northwest is semi-clonal and it would appear that multiple sequence types are contributing to the burden of disease in this region.
