Unofficial Histories: A Vision of Anthropology from the Margins

Initially given as the Presidential Address at the 100th Meeting of the AAA, this article examines the contributions women and minority anthropologists who have struggled to gain a place at the center of the discipline. Despite 25 years of scholarship on women and minorities, anthropology needs to go further in terms of paying attention to their pioneering efforts and the breadth of their scholarship. The article explores four currently important areas of creativity: (1) the transformation of field research through problem-oriented participant observation and "native anthropology," as exemplified by George Hunt, the young Margaret Mead, Delmos Jones; (2) the evolution of more dialogical forms of ethnographic writing, as pursued by Elsie Clews Parsons, Gladys Reichard, Ella Deloria, and Zora Neale Hurston; (3) sources of critique, as embodied in the work of Ruth Benedict and Michelle Rosaldo; (4) forms of activism, engaged in by Anita McGee, Benedict, Mead, and Alfonzo Ortiz.     

American Anthropology in the Middle Decades: A View from Hollywood

North American anthropology had an earlier interest in studies of the United States and in critical approaches than is often recognized. Such interests were pursued before World War II but were set aside during the war and in anthropology's postwar expansion. This perspective on anthropological history was inspired by the work of Hortense Powdermaker, specifically the disjunction between her 1930s research in segregated Mississippi and her pioneering study of Hollywood in the late 1940s. Reexamining that study highlights the theoretical framework that led to omissions in her account of Hollywood, while her explanation of movie content invites a more diachronic approach. Parallels between the history of the movies and that of cultural anthropology from the 1930s through the 1960s suggest how both were shaped by the Depression, World War II, and the Cold War.     

The Humanity of Animals and the Animality of Humans: A View from Biological Anthropology Inspired by J. M. Coetzee's Elizabeth Costello

In his novel Elizabeth Costello (2003), J. M. Coetzee's title character espouses philosophical perspectives on cruelty and the human condition in a series of fictionalized lectures. In particular, she takes on the question of human cruelty to animals. As novelist, Coetzee relies on lyrical statements about the nature of cruelty, analogies between the atrocities of fascism and factory farms, and ethical elitism to address these issues. In this article, I use anthropological data to investigate such constructed notions of "human cruelty" and "human nature." I end with a discussion of cross-cultural variation in animal use by humans and of the current animal rights movement. The goal of this article is to engage, anthropologically, perspectives on cruelty in human natures and our relations with other animals.     

"Describing our whole experience": the statistical philosophies of W. F. R. Weldon and Karl Pearson

There are two motivations commonly ascribed to historical actors for taking up statistics: to reduce complicated data to a mean value (e.g., Quetelet), and to take account of diversity (e.g., Galton). Different motivations will, it is assumed, lead to different methodological decisions in the practice of the statistical sciences. Karl Pearson and W. F. R. Weldon are generally seen as following directly in Galton’s footsteps. I argue for two related theses in light of this standard interpretation, based on a reading of several sources in which Weldon, independently of Pearson, reflects on his own motivations. First, while Pearson does approach statistics from this “Galtonian” perspective, he is, consistent with his positivist philosophy of science, utilizing statistics to simplify the highly variable data of biology. Weldon, on the other hand, is brought to statistics by a rich empiricism and a desire to preserve the diversity of biological data. Secondly, we have here a counterexample to the claim that divergence in motivation will lead to a corresponding separation in methodology. Pearson and Weldon, despite embracing biometry for different reasons, settled on precisely the same set of statistical tools for the investigation of evolution.     

"And This Is How You Shall Ask": Linguistics, Anthropology, and Education in the Work of David Smith

This article celebrates the life and work of David M. Smith, former Council on Anthropology and Education president and founder of the University of Pennsylania Ethnography in Education Research Forum, tracing his contributions to the fields of linguistics, anthropology, and education through the dual lens of his ten research principles and Walt Whitman's life advice. David Smith's pioneering efforts helped push disciplinary boundaries and generate innovations in sociolinguistics, pidgin and creole linguistics, ethnography and education, sociocultural studies of literacy, and Indigenous studies.     

A novel membrane-bound flavocytochrome c sulfide dehydrogenase from the colourless sulfur bacterium Thiobacillus sp. W5

A novel membrane-bound sulfide-oxidizing enzyme was purified 102-fold from the neutrophilic, obligately chemolithoautotrophic Thiobacillus sp. W5 by means of a six-step procedure. Spectral analysis revealed that the enzyme contains haem c and flavin. SDS-PAGE showed the presence of two types of subunit with molecular masses of 40 and 11 kDa. The smaller subunit contains covalently bound haem c, as was shown by haem staining. A combination of spectral analysis and the pyridine haemochrome test indicated that the sulfide-oxidizing heterodimer contains one molecule of haem c and one molecule of flavin. It appeared that the sulfide-oxidizing enzyme is a member of a small class of redox proteins, the flavocytochromes c, and is structurally most related to the flavocytochrome c sulfide dehydrogenase of the green sulfur bacterium Chlorobium limicola. The pH optimum of the enzyme is 8.6. At pH 9, the V _max was 2.1 ± 0.1 μmol cytochrome c (mg protein)^–1 min^–1, and the K _m values for sulfide and cytochrome c were 1.7 ± 0.4 μM and 3.8 ± 0.8 μM, respectively. Cyanide inhibited the enzyme by the formation of an N-5 adduct with the flavin moiety of the protein. On the basis of electron transfer stoichiometry, it seems likely that sulfur is the oxidation product. Received: 15 October 1996 / Accepted: 7 January 1997     

Vegetation and climate changes during the last 21 000 years in S.W. Africa based on a marine pollen record

A high resolution marine pollen record from site GeoB1023, west of the northern Namib desert provides data on vegetation and climate change for the last 21 ka at an average resolution of 185 y. Pollen and spores are mainly delivered to the site by the Cunene river and by surface and mid-tropospheric wind systems. The main pollen source areas are located between 13°S and 21°S, which includes the northern Namib desert and semi-desert, the Angola-northern Namibian highland, and the north-western Kalahari. The pollen spectra reflect environmental changes in the region. The last glacial maximum (LGM) was characterised by colder and more arid conditions than at present, when a vegetation with temperate elements such as Asteroideae, Ericaceae, and Restionaceae grew north of 21°S. At 17.5 ka cal. B.P., an amelioration both in temperature and humidity terminated the LGM but, in the northern Kalahari, mean annual rainfall in the interval 17.5-14.4 ka cal. B.P. was probably 100–150 mm lower than at present (400–500 mm/y). The Late-glacial to early Holocene transition includes two arid periods, i.e. 14.4–12.5 and 10.9–9.3 ka cal. B.P. The last part of the former period may be correlated with the Younger Dryas. The warmest and most humid period in the Holocene occurred between 6.3 and 4.8 ka cal. B.P. During the last 2000 years, human impact, as reflected by indications of deforestation, enhanced burning and overgrazing, progressively intensified.

Styles of Reasoning in Early to mid-Victorian Life Research: Analysis:Synthesis and Palaetiology

To better understand the work of pre-Darwinian British life researchers in their own right, this paper discusses two different styles of reasoning. On the one hand there was analysis:synthesis, where an organism was disintegrated into its constituent parts and then reintegrated into a whole; on the other hand there was palaetiology, the historicist depiction of the progressive specialization of an organism. This paper shows how each style allowed for development, but showed it as moving in opposite directions. In analysis:synthesis, development proceeded centripetally, through the fusion of parts. Meanwhile in palaetiology, development moved centrifugally, through the ramifying specialization of an initially simple substance. I first examine a community of analytically oriented British life researchers, exemplified by Richard Owen, and certain technical questions they considered important. These involved the neurosciences, embryology, and reproduction and regeneration. The paper then looks at a new generation of British palaetiologists, exemplified by W.B. Carpenter and T.H. Huxley, who succeeded at portraying analysts’ questions as irrelevant. The link between styles of reasoning and physical sites is also explored. Analysts favored museums, which facilitated the examination and display of unchanging marine organisms while providing a power base for analysts. I suggest that palaetiologists were helped by vivaria, which included marine aquaria and Wardian cases. As they became popular in the early 1850s, vivaria provided palaetiologists with a different kind of living and changing evidence. Forms of evidence, how they were preserved and examined, and career options all reinforced each other: social and epistemic factors thus merged.     

Loss of the gene for the alpha subunit of ATP synthase (ATP5A1) from the W chromosome in the African grey parrot (Psittacus erithacus)

This study describes the results of an analysis using Southern blotting, the polymerase chain reaction, and sequencing which shows that the African grey parrot (Psittacus erithacus) lacks the W-chromosomal gene for the alpha subunit of mitochondrial ATP synthase (ATP5A1W). Additional evidence shows that in other psittacines a fragment of the ATP5A1W gene contains five times as many nonsynonymous nucleotide replacements as the homologous fragment of the Z gene. Therefore, whereas in these other psittacines the corresponding ATP5A1Z protein fragment is highly conserved and varies by only a few, moderately conservative amino acid substitutions, the homologous ATP5A1W fragments contain a considerable number of, sometimes highly nonconservative, amino acid replacements. In one of these species, the ringneck parakeet (Psittacula krameri), the ATP5A1W gene is present in an inactive form because of the presence of a nonsense codon. Other changes, possibly leading to an inactive ATP5A1W gene product, involve the substitution of arginine residues by cysteine in the ATP5A1W protein of the mitred conure (Aratinga mitrata) and the blue and gold macaw (Ara ararauna). The data suggest also that although the divergence of the psittacine ATP5A1W and ATP5A1Z genes preceeded the origin of the psittacidae, this divergence occurred independently of a similar process in the myna (Gracula religiosa), the outgroup used in this study.

Electrophoretic study and genetic affinity in theCampanula elatines andC. fragilis (Campanulaceae) rock-plants group from Italy and W. Jugoslavia

Variability and genetic divergence of 11 field populations of seven species of theCampanula elatines andC. fragilis rock-plants group from the Mediterranean and pre-Alpine areas have been studied by starch-gel electrophoretic techniques.Campanula isophylla, C. elatines, C. elatinoides, C. fragilis subsp.fragilis and subs.cavolinii, C. garganica were collected in Italy, whilstC. fenestrellata subsp.istriaca andC. portenschlagiana came from W. Jugoslavia. Twelve enzymatic loci for each population were genetically analysed: PGI-1 and 2, PGM-2, IDH-1 and -2, SKDH, ME, ADH, GOT-2, MPI-1 and -2, SOD-1. The genetic distances among the above mentioned entities have been calculated by Nei's index and depicted in a dendrogram.     

Heterosexual interactions in laboratory-housed stumptail macaques (Macaca arctoides): observations during the menstrual cycle and after ovariectomy.

Heterosexual interactions of pairs of stumptail macaques (Macaca arctoides) were studied in relation to the female menstrual cycle and after ovariectomy. Five intact male and 10 tubal-ligated female macaques were observed in laboratory pair tests of 20-mins duration, and data were obtained on various male and female behaviors. Each male was tested with the same two females during four 40-day observation periods. Males were tested daily and females were tested every other day. After two 40-day testing periods, one female partner of each male was ovariectomized and the other was sham-operated. Blood was collected regularly from the females during the course of observation and serum levels of estradiol and progesterone were determined by radioimmunoassay. The midcycle peak of estradiol was observed to occur approximately 18 days prior to menses. A distinct secondary peak in estradiol was observed to occur during the luteal phase of all cycles examined. Of 28 different male and female behaviors studied only female presentation to male sexual contact showed a significant midcycle peak related to the endogenous estradiol surge. After ovariectomy a significant decrease in the frequency of several male copulatory behaviors was observed, but most males continued to copulate regularly with their spayed partners throughout the period of this study. Thus, the pattern of copulatory behavior observed in stumptail macaques over the cycle of the female partner and subsequent to ovariectomy differs from that observed in other macaque species studied in the laboratory. It is concluded that cyclical fluctuations in the level of ovarian hormones are not significantly related to measures of sexual interactions in laboratory tests of this species, although the maintenance of copulation and associated behaviors at high levels depends to some degree upon the ovary.     

Limitation to Photosynthesis in Water-stressed Leaves: Stomata vs. Metabolism and the Role of ATP

Decreasing relative water content (RWC) of leaves progressivelydecreases stomatal conductance (g_s), slowing CO₂ assimilation(A) which eventually stops, after which CO₂ is evolved. In somestudies, photosynthetic potential (A_pot), measured under saturatingCO₂, is unaffected by a small loss of RWC but becomes progressivelymore inhibited, and less stimulated by elevated CO₂, below athreshold RWC (Type 1 response). In other studies, A_pot andthe stimulation of A by elevated CO₂ decreases progressivelyas RWC falls (Type 2 response). Decreased A_pot is caused byimpaired metabolism. Consequently, as RWC declines, the relativelimitation of A by g_s decreases, and metabolic limitation increases.Causes of decreased A_pot are considered. Limitation of ribulosebisphosphate (RuBP) synthesis is the likely cause of decreasedA_pot at low RWC, not inhibition or loss of photosynthetic carbonreduction cycle enzymes, including RuBP carboxylase/oxygenase(Rubisco). Limitation of RuBP synthesis is probably caused byinhibition of ATP synthesis, due to progressive inactivationor loss of Coupling Factor resulting from increasing ionic (Mg²⁺)concentration, not to reduced capacity for electron or protontransport, or inadequate trans-thylakoid proton gradient (pH).Inhibition of A_pot by accumulation of assimilates or inadequateinorganic phosphate is not considered significant. DecreasedATP content and imbalance with reductant status affect cellmetabolism substantially: possible consequences are discussedwith reference to accumulation of amino acids and alterationsin protein complement under water stress.     

Eimeria procyonis sp. n., an Isospora sp., and a Redescription of E. nuttalli Yakimoff and Matikaschwili, 1932 (Protozoa: Eimeriidae) from the American Raccoon (Procyon lotor)

SYNOPSIS. Thirty-two of 48 raccoons examined were infected with a previously undescribed species of Eimeria which is herein named E. procyonis. Of the 32 infected animals, 10 also harbored E. nuttalli and 1 had Isospora sp. oocysts.
The ellipsoid to ovoid oocysts of E. procyonis measured 23.4 × 18.0 (16–29 × 13–24) μm; its sporocysts measured 12.1 × 9.3 (11.5–15 × 7–10) μm, each containing a slightly flattened substiedal body. The sporocyst residuum consisted of numerous scattered granules each ∼1 μm in diameter. The oocyst wall was double-layered. The outer layer appeared rough and pitted, measuring 1.5 μm, except at the micropyle where it was 1 μm thick.
The oocysts of the Isospora sp. measured 16.8 × 13.7 (16–18.5 × 12.5–15.5) μm. The wall consisted of a single layer ∼0.5 μm thick. The sporocysts measured 11.2 × 9.1 (9.5–11.5 × 8–10) μm, and each contained 4 elongate sporozoites. The oocysts of E. nuttalli measured 17.5 × 13.6 (12-21 × 11-15) μm, with a smooth single-layered wall approximately 0.7 μm thick. The sporocysts measured 12.2 × 7.1 (9-13 × 5.5–11) μm. Each sporocyst had a thin, dark, Stieda body and the sporocyst residuum consisted of many fine granules.     

The Status of Knowledge of the Genus Ecdyonurus in the Iberian Peninsula,with Description of Two New Species of the E. venosus Group from Spain (Ephemeroptera: Heptageniidae)

As a result of studies of material of Ecdyonurus from Spain, nymphs and adults of two new species, E. baeticus sp. n. and E. olgae sp. n., are described. Three species described by Navás must be considered as nomina dubia (E. diversus Navás, 1923, E. excelsus Navás, 1927 and E. fluminum var. speciosus Navás, 1915). Variability in adults of E. venosus is figured and discussed.     

Conservation of translation initiation sites based on dinucleotide frequency and codon usage in Escherichia coli K-12 (W3110): non-random distribution of A/T-rich sequences immediately upstream of the translation initiation codon.

Dinucleotide frequencies are useful for characterizing consensus elements as a minimum unit of nucleotide sequence because the neighborhood relations of nucleotide sequences are reflected in dinucleotides. Using a consensus score based on dinucleotide frequencies and intra-species codon usage heterogeneity, denoted by the Z1 parameter, we report the relationship between nucleotide conservation at the translation initiation sites of genes in the Escherichia coli K-12 genome (W3110) and codon usage in its downstream genes. Significant positive correlations were obtained in three regions centered at -13, -4, and +7, which correspond to the Shine-Dalgarno element, the A + T element immediately upstream of the translation initiation site, and the downstream box, respectively.     

Maintenance of the shore-level size gradient in the marine snail Tegula funebralis (A. Adams): Importance of behavioral responses to light and sea star predators

The intertidal gastropod, Tegula funebralis (A. Adams) exhibits a shore-level size gradient with mean shell size increasing in a down-shore direction. Snails transferred to zones where they do not usually occur migrated back towards their original zone, thus re-establishing a size gradient and implying differential movement among size classes. Both large (≥2.1 cm shell width) and small (≤ 1.77 cm) snails were photonegative on a horizontal surface and geonegative in the laboratory; there were no statistical differences between size classes. Light, however, inhibited upward, or caused downward, movement of large snails on vertical surfaces. Small snails were unaffected, ranging higher on illuminated vertical surfaces than large snails. Both sizes exhibited similar distributions in the dark. In an experimental chamber providing both emersed and immersed surfaces, T. funebralis established vertical size gradients when the chamber was illuminated from above. It is suggested that light is an important factor in the formation and maintenance of Tegula's shore-level size gradient.In response to water-borne chemicals derived from the sea star Pisaster ochraceus (Brandt), large snails moved up vertical surfaces in greater proportion than small. In response to contact with the predator, large snails moved away faster than small and individuals collected from crevices in the field moved away slower than those collected from open rock faces. Although predation may select for a size gradient in Tegulafunebralis, it is unlikely that responses to predatory sea stars directly and proximally cause or maintain them over the short term.
