Book Review of Plains Earthlodges: Ethnographic and Archaeological Perspectives Edited by Donna C. Roper and Elizabeth P. Pauls

Nomadic Plains peoples such as the Cheyenne and Sioux have become the stereotypical image of North American Indians in general. In contrast to the hunting and gathering lifestyle of these groups, however, many Plains tribes lived in settled villages and grew extensive garden crops through much of the past millennium. These groups developed a habitation distinctly characteristic of the Plains village way of life-sturdy, earth-covered timber structures known as earth lodges. The remains of thousands of these structures dot the landscape of the Central and Northern Plains. Lodges of various forms persisted from about 1000 CE into the twentieth century. Particularly characteristic of the Pawnee, Arikara, Mandan, and Hidatsa, earthlodges were also adopted by several other Plains tribes. In this well-illustrated volume eight authors offer nine essays that explore the earth lodge as a subject warranting archaeological and anthropological research in its own right and from numerous perspectives.

An Investigation of Wild Bee Diversity and Abundance in Plots Managed by The Nature Conservancy in South-Central Nebraska and of Beneficial Arthropods Associated with Native Nebraska Flora

Insect pollination is an essential ecosystem service, and bees are the principal pollinators of wild and cultivated plants. Habitat management and enhancement are a proven way to encourage wild bee populations, providing them with food and nesting resources. I examined bee diversity and abundance in plots managed by The Nature Conservancy near Wood River, NE. The plots were seeded with 2 seed mixes at 2 seeding rates: high diversity mix at the recommended rate, high diversity mix double the recommended rate, Natural Resources Conservation Service (NRCS) conservation planting (CP) 25 mix at one-half the recommended rate, and NRCS CP25 mix at the recommended rate. I measured wild bee abundance and diversity, and established a database of wild bees associated with the plots. I also compared genus richness and abundance among the plots using and aerial net and blue vane traps to collect bees. Significant differences were not observed in genus richness and diversity among the plots; however, plot size and the ability of blue vane traps to draw bees from a long distance may have influenced my results. In 2008, 15 genera and 95 individual bees were collected using an aerial net and in 2009, 32 genera and 6,103 individual bees were collected using blue vane traps. I also studied the beneficial insects associated with native Nebraska flora. Seventeen species of native, perennial flora were established in 3 separate plots located in eastern Nebraska. I transplanted four plants of each species in randomized 0.61 m x 0.61 m squares of a 3.05 m x 9.14 m plot. Arthropods were sampled using a modified leaf blower/vacuum. Insects and other arthropods were identified to family and organized into groups of predators, parasites, pollinators, herbivores, and miscellaneous. Associations between plant species and families of beneficial arthropods (predators, parasites, and pollinators) were made. Pycnanthemum flexuosum Walter attracted significantly more beneficial arthropod families than 7 other species of plants tested. Dalea purpurea Vent and Liatris punctata Hook also attracted significantly fewer beneficial arthropod families than 4 other species of plants tested. In total, 31 predator, 11 parasitic, 4 pollinator, 31 herbivore, and 10 miscellaneous families of arthropods were recorded.

Immatures of Dicrepidius Eschscholtz, 1829 and Dipropus Germar, 1839 (Elateridae, Elaterinae, Ampedini: Dicrepidiina)

The larva of Dicrepidius ramicornis (Palisot de Beauvois) and pupa of Dipropus brasilianus (Germar) are described. The larva of D. brasilianus is redescribed. The immatures of both species are illustrated. Comparisons among the known larvae of Dipropus species and between the two genera are presented. A provisional key to Dicrepidiina genera with known larvae is provided.

Establishment of the bacterial fecal community during the first month of life in Brazilian newborns

OBJECTIVE: The establishment of the intestinal microbiota in newborns is a critical period with possible long-term consequences for human health. In this research, the development of the fecal microbiota of a group of exclusively breastfed neonates living in low socio-economic conditions in the city of Sao Paulo, Brazil, during the first month of life, was studied. METHODS: Fecal samples were collected from ten neonates on the second, seventh, and 30th days after birth. One of the neonates underwent antibiotic therapy. Molecular techniques were used for analysis; DNA was extracted from the samples, and 16S rRNA libraries were sequenced and phylogenetically analyzed after construction. A real-time polymerase chain reaction (PCR) was performed on the samples taken from the 30th day to amplify DNA from Bifidobacterium sp. RESULTS: The primary phylogenetic groups identified in the samples were Escherichia and Clostridium. Staphylococcus was identified at a low rate. Bifidobacterium sp. was detected in all of the samples collected on the 30th day. In the child who received antibiotics, a reduction in anaerobes and Escherichia, which was associated with an overgrowth of Klebsiella, was observed throughout the experimental period. CONCLUSION: The observed pattern of Escherichia predominance and reduced Staphylococcus colonization is in contrast with the patterns observed in neonates living in developed countries.

Strategies for Multivessel Revascularization in Patients with Diabetes

BACKGROUND In some randomized trials comparing revascularization strategies for patients with diabetes, coronary-artery bypass grafting (CABG) has had a better outcome than percutaneous coronary intervention (PCI). We sought to discover whether aggressive medical therapy and the use of drug-eluting stents could alter the revascularization approach for patients with diabetes and multivessel coronary artery disease. METHODS In this randomized trial, we assigned patients with diabetes and multivessel coronary artery disease to undergo either PCI with drug-eluting stents or CABG. The patients were followed for a minimum of 2 years (median among survivors, 3.8 years). All patients were prescribed currently recommended medical therapies for the control of low-density lipoprotein cholesterol, systolic blood pressure, and glycated hemoglobin. The primary outcome measure was a composite of death from any cause, nonfatal myocardial infarction, or nonfatal stroke. RESULTS From 2005 through 2010, we enrolled 1900 patients at 140 international centers. The patients' mean age was 63.1 +/- 9.1 years, 29% were women, and 83% had three-vessel disease. The primary outcome occurred more frequently in the PCI group (P=0.005), with 5-year rates of 26.6% in the PCI group and 18.7% in the CABG group. The benefit of CABG was driven by differences in rates of both myocardial infarction (P<0.001) and death from any cause (P=0.049). Stroke was more frequent in the CABG group, with 5-year rates of 2.4% in the PCI group and 5.2% in the CABG group (P=0.03). CONCLUSIONS For patients with diabetes and advanced coronary artery disease, CABG was superior to PCI in that it significantly reduced rates of death and myocardial infarction, with a higher rate of stroke.

Fauna e Flora do Brasil (especialmente do Mato Grosso) segundo Joseph Barbosa de Sáa (1769): (Dialogos geograficos, coronologicos, polliticos, e naturais, escripos [sic] por Joseph Barbosa de Sáa nesta Villa Reyal do Senhor Bom Jesus do Cuyaba – Manuscrito 235 da Biblioteca Pública do Porto)

Joseph Barbosa de Sáa (? – 1775), mais conhecido por seus escritos sobre a história do estado do Mato Grosso, Brasil, completou em 1769 um volumoso (408 fólios) e erudito manuscrito, intitulado “Dialogos geograficos, coronologicos, polliticos e naturais”, que nunca foi publicado na íntegra. Esse manuscrito está depositado na Biblioteca Pública do Porto (manuscrito no. 235), em Portugal. Dez capítulos desse manuscrito tratam dos produtos naturais do Brasil (acima de mil, quase a metade sendo animais), observados por Sáa ao longo da costa do Rio de Janeiro, em São Paulo, sul de Goiás e especialmente no Mato Grosso, sendo a primeira monografia sobre a história natural deste último estado. Esses capítulos são aqui transcritos e comentados.
