Cold Code: The global initiative to DNA barcode amphibians and nonavian reptiles

DNA barcoding facilitates the identification of species and the estimation of biodiversity by using nucleotide sequences, usually from the mitochondrial genome. Most studies accomplish this task by using the gene encoding cytochrome oxidase subunit I (COI; Entrez COX1). Within this barcoding framework, many taxonomic initiatives exist, such as those specializing in fishes, birds, mammals, and fungi. Other efforts center on regions, such as the Arctic, or on other topics, such as health. DNA barcoding initiatives exist for all groups of vertebrates except for amphibians and nonavian reptiles. We announce the formation of Cold Code, the international initiative to DNA barcode all species of these 'cold-blooded' vertebrates. The project has a Steering Committee, Coordinators, and a home page. To facilitate Cold Code, the Kunming Institute of Zoology, Chinese Academy of Sciences will sequence COI for the first 10 specimens of a species at no cost to the steward of the tissues. © 2012 Blackwell Publishing Ltd.

Global sampling reveals low genetic diversity within Compsopogon (Compsopogonales, Rhodophyta)

Twenty-five specimens of the freshwater red alga Compsopogon were collected from locations in North America, South America, Europe, Asia, Australasia and Oceania, and from an aquarium, with the goal of determining genetic diversity among specimens and ascertaining the number of phylogenetic species. Specimens were morphologically identified as having either the 'caeruleus' morphology, with regular polyhedral cortical cells, or the 'leptoclados' morphology, with irregular cortical cells with rhizoidal outgrowths. The 'leptoclados' morphology has been used by some researchers to distinguish the genus Compsopogonopsis from Compsopogon, or at least to distinguish C. leptoclados from other Compsopogon species. Sequence data for the rbcL gene and cox1 barcoding region were obtained for most specimens. In addition, SSU and partial LSU (barcode) rDNA were explored for a few specimens, but all sequences were identical. For the 25 newly generated and eight previously published rbcL gene data, there were seven unique haplotypes, but the sequence divergence was very low (≤7 bp, ≤ 0.7%). One haplotype was widespread, represented by 21 specimens from diverse locations in all regions sampled. Likewise, the 22 new and one previously published cox1 barcode region sequences yielded seven unique haplotypes with little sequence divergence (≤13 bp, ≤ 2.0%). One haplotype was widespread, being shared among 16 specimens from all regions. The combined molecular and morphological data showed no genetic differentiation between the 'caeruleus' and 'leptoclados' morphologies. The ubiquitous distribution of Compsopogon in tropical/subtropical regions and its low genetic variation are probably facilitated by the alga's ability to tolerate a wide range of stream conditions and its propagation via asexual spores. Given the findings of previous culture-based studies, morphometric research and field observations, coupled with the results of our study, we conclude there is only a single monospecific genus worldwide and that the species is correctly called C. caeruleus, since this is the oldest validly published name; all other previously described species of Compsopogon and Compsopogonopsis are synonyms. © 2013 British Phycological Society.

The tourism sector and the global economic crisis: development implicatins for the Caribbean

Over the past two years the global economy has experienced substantial economic turmoil, resulting in severe economic contraction. While there has been a recent return to growth, this situation has impacted all economic sectors worldwide. In the highly tourism-dependent region of the Caribbean, the impact of the global economic crisis has been most notable on the tourism sector, which, from the early 1990s, became the key driver of economic growth for the region. The eventual emergence of this sector reflects an economic development history which was previously underpinned by the export of agricultural commodities, and subsequently by the adoption of the import substitution industrialization model as promulgated by Arthur Lewis. This was further stimulated by spectacular economic contraction in Caribbean economies during the 1980s as a result of changes in the global terms of trade for commodities, generally low levels of competitiveness for manufactured goods, as well as weak institutional and governance frameworks. Ultimately, many economies began to reflect fiscal and balance of payments constraints. By the end of the 1990s, too, evidence of declining competitiveness even in the tourism sector began to become apparent particularly when evaluated under the framework of the Butler Tourism Area Life- Cycle (TALC) model. The recent economic crisis, therefore, provides an opportunity to reflect on the overall approach to economic development in the Caribbean, and to assess the implications of the region’s response to the crisis. This analysis makes the case for the future development of the sector to be based on two broad strategies. The first is to deepen the integration of the tourism sector into the broader economy through the diversification of the regional tourism product, as well as the enhancement of linkages with other sectors, while the second is to expand the tourism sector into a total service economy through the introduction of new services. Considering linkages, the development of clusters and value chains to support the tourism sector is identified with respect to agriculture and food, handicraft, and furnishings. Among the new services identified are education, wellness, yachting and boating, financial services, and information and communications technologies (ICT). This overall strategy is deemed to be better suited to the macroeconomic realities of the Caribbean, where high labour costs and other structural rigidities require a high-valued specialty tourism product in order to sustain the sector’s global competitiveness.

A cultura ribeirinha entre o saber local e o saber global numa visão etnomatemática

Esta dissertação é o resultado de uma pesquisa que teve como objetivo analisar como um grupo de ribeirinhos, moradores da ilha João Pilatos (Ananindeua - PA), relaciona os conhecimentos ministrados no curso de formação para empreendedores rurais com os conhecimentos que possui da tradição ribeirinha e, em especial, os conhecimentos matemáticos. A parte empírica dessa pesquisa aconteceu em dois lugares e em momentos diferentes: o primeiro deles ocorreu na ilha João Pilatos, onde foram coletadas informações sobre o histórico das comunidades existentes na ilha, sobre os afazeres do cotidiano e sobre as práticas de pesca, de plantio, de coleta na floresta, de preparação do carvão e sobre a comercialização desses produtos. Nesse momento, os únicos recursos utilizados foram caderno e caneta para anotações e a técnica da escuta e do diálogo. O segundo momento ocorreu no curso de formação para empreendedores rurais ministrado pelo SENAR (Serviço Nacional de Aprendizagem Rural). Nesse local, minha participação no grupo estava restrita a escutar e olhar os gestos e expressões faciais de todos os presentes. Em função disso, a observação seguida de anotações foram as técnicas utilizadas durante esse período. Após o curso, foram realizadas entrevistas semi-estruturadas com os sujeitos dessa pesquisa com o objetivo de complementar as anotações feitas durante o curso. A Sociologia e a Etnomatemática foram as bases teóricas utilizadas na organização e análise das informações de campo. No campo da sociologia, busquei Antony Giddens, Renato Ortiz e Georges Balandier para analisar o fenômeno da globalização econômica e social sobre a cultura ribeirinha e Berger & Luckmann com a sua teoria "A construção social da realidade" para analisar o cotidiano e a produção de conhecimento na vida cotidiana. No campo da Etnomatemática, utilizei a Etnomatemática numa abordagem D'Ambrosiana e as pesquisas da área. Ao final das análises, no que diz respeito à matemática, percebi que ter domínio sobre os cálculos e fórmulas dessa área do conhecimento não era condição suficiente para que os sujeitos da pesquisa alcançassem o objetivo do curso, uma vez que tanto para os empreendedores quanto para os ribeirinhos a matemática era uma forma de ver e explicar o mundo que tinha significados específicos de cada contexto. A partir desse conflito cultural, é possível indicar que os sujeitos da pesquisa atingiriam o objetivo do curso e estabeleceriam o maior número de relações entre a matemática escolar e os saberes da tradição se a matemática estudada, no curso, fosse ressignificada no contexto ribeirinho. Como consequência da primeira análise, também é possível concluir que, mediante a concepção atualmente existente no ambiente escolar que separa e não apenas distingue os valores culturais, que considera a produção de conhecimentos proveniente apenas de ambientes acadêmicos científicos e que esses tipos de conhecimentos devem ser socializados de forma disciplinar, as possibilidades de um maior número de relações entre os saberes da tradição cultural e da tradição científica têm mais chances de ocorrer em ambientes não escolares.

Luxation injuries in primary teeth: a retrospective study in children assisted at an emergency service

ABSTRACT: The purpose of this study was to analyze luxation injuries in children between the ages of 0 and 5 years treated at an emergency service department. A total of 1,703 records, corresponding to a period of 10 years at the Emergency Center of the Baby Clinic at Londrina State University, Brazil, were analyzed. The age, gender, etiologic factors, type of injury, injured teeth, treatment and time interval between injury and treatment were determined for each patient. Of the examined records, 409 patients met the study criteria and included a total of 679 injured teeth. Statistical analyses were carried out using the chi-square test with the level of significance set at 5%. Trauma incidence was higher in boys (57.0%) and in children less than two years of age (40.3%). Falling while walking or running was the most predominant etiologic factor (37.7%), and the most prevalent type of injury was subluxation (32.6%). Luxation injuries decreased with increasing age (p = 0.045). Treatment usually occurred within the first 1-15 days and was significantly associated with the type of trauma (p = 0.041). "Monitor only" was the treatment most frequently observed (74.0%). In conclusion, more luxation injuries were found in younger children, predominantly in boys. Falls resulting from walking or running were the etiologic factor most observed, with subluxation as the most common type of trauma. Treatment usually occurred within the first 15 days after the injury. Despite the severity of these injuries, "monitor only" was the eligible treatment.
