L’accès et le partage des avantages des savoirs traditionnels en Amérique latine : comment les droits de propriété intellectuelle peuvent empêcher la biopiraterie

Ce travail se situe dans la perspective des études sur la protection des savoirs traditionnels contre la biopiraterie commise par quelques industries pharmaceutiques et cosmétiques. Malgré le débat qui s’est déroulé à ce sujet après la signature de la Convention sur la diversité biologique, ces patrimoines culturels continuent d’être largement menacés. L’étude se propose d’analyser les mécanismes capables de protéger contre la biopiraterie les savoirs traditionnels associés à la biodiversité qui intéressent l’industrie pharmaceutique, et ce, par le biais des droits de propriété intellectuelle existants aussi bien à l’échelle internationale que dans le cadre des législations nationales. Ces mécanismes sont évalués quant à leur efficacité, en vue d’en identifier les plus intéressants, susceptibles d’être adoptés soit par des pays qui ne disposent pas encore de législation en matière de protection des savoirs traditionnels soit pour être utilisés dans le cadre international. Avec cet objectif, le présent travail dressera un panorama concernant la législation du Brésil, du Costa Rica et du Pérou. En outre, seront mises en exergue par la suite les différentes conventions en lien avec les savoirs traditionnels, à savoir la Convention sur la diversité biologique, le Protocole de Nagoya, le Comité intergouvernemental de la propriété intellectuelle relative aux ressources génétiques, aux savoirs traditionnels et au folklore de l’Organisation mondiale de la propriété intellectuelle. L’analyse menée a mis en lumière un certain nombre de dispositions assez efficaces pouvant être utilisées de façon optimale par des pays ne disposant pas de législation en matière de protection des savoirs traditionnels ou encore pouvant être intégrées dans des traités internationaux en la matière, afin de rendre lesdits traités plus efficaces sur le plan pratique. Bien plus, ladite analyse démontre que l’Accord sur les aspects des droits de propriété intellectuelle qui touchent au commerce est actuellement l’accord le plus coercitif et le plus contraignant lorsque l’on veut mener une lutte efficace contre la biopiraterie. Par ailleurs, en s’appuyant sur des fondements théoriques constructivistes, notre analyse essaye de démontrer que les pays du Sud, riches en biodiversité et en savoirs traditionnels, peuvent véritablement impulser un mouvement en faveur d’une législation internationale efficace en matière de protection des savoirs traditionnels

A Pollen Chase Experiment; Examining Varying Levels of Embryonic Inbreeding Depression

A pollen chase experiment was performed upon three Costa Rican populations of Witheringia solanacea to examine the breakdown of genetically enforced self incompatibility (SI) and the extent of embryonic inbreeding depression. Self-pollen was applied in the bud, with outcross pollen applied one day later, and outcross pollinations at both intervals as a control. A variety of responses were found among the populations. BOHS readily accepted self pollen and suffered from very low inbreeding depression. Monteverde and Las Cruces both have lower fruit set with self-pollination precedence indicating that bud pollinations can overcome the self-incompatibility response and that embryonic death due to inbreeding depression causes fruit failure. The treatment:control fruit set is higher for the Las Cruces plants indicating stronger SI response Self-precedence seeds from the Las Cruces plants are likely to be outcrossed. Self-precedence seeds from Monteverde are likely selfed.

Estrutura genética populacional de Heliconius erato e Heliconius melpomene (Lepidoptera: Nymphalidae) em fragmentos de Mata Atlântica do Rio Grande do Norte

Extensive studies using molecular markers on butterflies have shown how a highly fragmented landscape may result in the reduction of gene flow among patches of habitat and, consequently, increase genetic differentiation among populations. However, little is known about Heliconius geographical structure and the effects of fragmentation on the connectivity of populations. Furthermore, findings on the effects of the population structure on the dynamics of mimicry evolution in Heliconius butterflies need to be tested in H. erato and H. melpomene specimens found in other locations other than Central and northern South Americas. For the present study, we had two motivations: (1) compare the population structure of H. erato and H. melpomene given the highly fragmented Brazil s Atlantic Forest habitat; and (2) studying population structure of co-mimics could give us insights into the dynamics of mimicry evolution. For this, we analysed the spatial structure and connectivity of eight populations of Heliconius butterflies, in a total of 137 H. erato specimens and 145 H. melpomene specimens, using nine microsatellites loci, 1144 AFLPs markers and 282 mitochondrial DNA sequences. In general, both species exhibited evidence of population subdivision but no isolation by distance indicating some extent of genetic differentiation among populations. Contrary to Kronforst & Gilbert s (2008) Costa Rican Heliconius, H. melpomene exhibited more genetic differentiation than H. erato based on nuclear markers. However, for mitochondrial DNA, H. erato populations showed more genetic differentiation than H. melpomene. Our results corroborate to other studies on Heliconius butterflies concerning the pronounced population subdivision and local genetic drift found in this genus. Nevertheless, the pattern of this differentiation varies significantly from the pattern found in studies conducted in Central America, where H. erato is generally more differentiated and structured than H. melpomene, based on nuclear markers. This different pattern may reflect different evolutionary histories of Heliconius species in Northeastern Brazil s Atlantic Forest

(Table 1) Light minerals in sand at DSDP Leg 84 holes

The Middle America active continental margin is the best-sampled active plate margin to date, having been drilled during Legs 84, 67, and 66. With nine sites drilled on the continental slope of Guatemala and an additional site drilled on the Costa Rican slope, a summary of slope sediments and sedimentary processes can be made. Sediments are easily subdivided into a thick apron of Neogene and Quaternary volcanically derived hemipelagic and turbidite mud and mudstone and a thinner, more varied assemblage of mostly Paleogene mudstone, radiolarian mudstone, and limestone. This latter assemblage may contain hiatuses or be completely lacking between slope deposits and basement. Cores from the foot of the continental slope (Core 567A-19) consist of Campanian micrite. The pre-Neogene section is much thicker and of more terrigenous provenance beneath the forearc basin landward of the forearc structural high than on the continental slope. Sedimentary processes of the Neogene and Quaternary slope sediments include reworking of hemipelagic and turbidite deposits. Redeposition by slumping, plastic flow, and turbidity current-documentable through benthic foraminiferal analysis-occurs in intracanyon and canyon settings. Erosion by slumping and by turbidity current and deposition of mud or sand in canyons and in local depressions on the continental slope and different rates of sediment accumulation result in dramatic thickness variations of lithologic units over small distances in localized pockets of sand in small filled canyons on the slope or in sediment ponds, and in high-relief basement topography. The age of sediment overlying igneous basement ranges from Cretaceous to Quaternary. Gas hydrate was visible or inferred present at every site drilled during Leg 84. Nevertheless, except for a small amount in the last core, it was not recovered in sufficient quantities to be visible at Site 568, a site specifically chosen for the study of hydrate and located near Site 496, which was abandoned during Leg 67 because of the dangerous abundance of hydrates. The association of hydrate with porous, coarser sediment results in a distribution as localized and unpredictable as the slope sands off Guatemala, which do not occur in beds coherent enough to produce acoustic reflection. Although the normal lithologic section at Sites 567 and 496 limits the volume of sediment that could be part of an accretionary prism offshore Guatemala and the volume of sediment in the Trench axis is not sufficient to argue for significant accumulation of Cocos Plate sediments, the varied lithology and attenuated thickness of pre-Neogene sediment seaward of the forearc structural high do not exclude earlier accretion from the history of the Guatemalan continental margin.

10Be data for sediments from DSDP Leg 56 and ODP Leg 170

Sediment accretion and subduction at convergent margins play an important role in the nature of hazardous interplate seismicity (the seismogenic zone) and the subduction recycling of volatiles and continentally derived materials to the Earth's mantle. Identifying and quantifying sediment accretion, essential for a complete mass balance across the margin, can be difficult. Seismic images do not define the processes by which a prism was built, and cored sediments may show disturbed magnetostratigraphy and sparse biostratigraphy. This contribution reports the first use of cosmogenic 10Be depth profiles to define the origin and structural evolution of forearc sedimentary prisms. Biostratigraphy and 10Be model ages generally are in good agreement for sediments drilled at Deep Sea Drilling Project Site 434 in the Japan forearc, and support an origin by imbricate thrusting for the upper section. Forearc sediments from Ocean Drilling Program Site 1040 in Costa Rica lack good fossil or paleomagnetic age control above the decollement. Low and homogeneous 10Be concentrations show that the prism sediments are older than 3-4 Ma, and that the prism is either a paleoaccretionary prism or it formed largely from slump deposits of apron sediments. Low 10Be in Costa Rican lavas and the absence of frontal accretion imply deeper sediment underplating or subduction erosion.

Análise da possível expansão internacional de empresas brasileiras de real estate residencial para o mercado costarriquenho, uma abordagem SWOT.

Devido ao crescimento e à experiência adquirida pelas empresas brasileiras de real estate residencial nos últimos anos, e às características próprias desse setor, os mercados internacionais poderiam ser considerados como possíveis alvos para essas empresas. Por exemplo, no mercado residencial costarriquenho, incentivos para projetos residenciais de alta densidade populacional, reformas nos processos para a obtenção dos alvarás de construção e mudanças demográficas e culturais, parecem propiciar um ambiente favorável para empresas dessa indústria. Portanto, o objetivo do presente trabalho é estudar uma possível expansão geográfica de empresas brasileiras de real estate no mercado residencial costarriquenho, a partir da estruturação de uma análise de abordagem SWOT dos elementos necessários para tal incursão. Para isso, realizou-se uma revisão bibliográfica na busca dos elementos estratégicos do ambiente interno de empresas de real estate residencial que devem ser considerados para processos de internacionalização, identificando-se 12 forças e 10 fraquezas desta revisão. Ademais, analisou-se: o mercado residencial; a macroeconomia, e as conjunturas político-legais e socioculturais da Costa Rica, na procura de fatores que devem ser tomados em conta por parte de empresas de real estate ao ingressar nesse país, distinguindo-se 24 oportunidades e 20 ameaças dessa análise. Para complementar o estudo, foi avaliada a atratividade do mercado residencial costarriquenho para receber investimentos por onze importantes empresas do setor de real estate residencial brasileiro, por meio de um questionário estruturado com os elementos identificados na primeira parte do trabalho. Os resultados mostraram que, no momento da avaliação, as empresas entrevistadas deram maior atenção ao tamanho do mercado e às características do sistema financeiro para o setor residencial, e identificaram a carência do conhecimento local e sua cultura empresarial, como os elementos que dificultariam sua internacionalização. Conclui-se sobre a possível internacionalização de empresas brasileiras de real estate residencial para o mercado da Costa Rica, que elementos desde uma perspectiva econômica racional e principalmente contingencial definem essa estratégia, não sendo viável nem vantajoso idealizar um processo de internacionalização nesse mercado, devido às atuais condições de seus mercados locais e aos elementos do ambiente interno que várias dessas empresas apresentam.

Sampling tissue for DNA analysis of trees: Trunk cambium as an alternative to canopy leaves

The number of studies of tropical tree species that use molecular tools is increasing, most of which collect leaf tissue for genomic DNA extraction. In tropical trees the canopy is not only frequently inaccessible, but also, once reached, the leaf tissue is often heavily defended against herbivory by high concentrations of anti-predation compounds, which may inhibit downstream applications, particularly PCR. Cambium tissue, accessed directly from the tree trunk at ground level, offers a readily accessible resource that is less hampered by the presence of defensive chemicals than leaf tissue. Here we describe a simple method for obtaining tissue from the cambial zone for DNA extraction and test the applicability of the method in a range of tropical tree species. The method was used successfully to extract DNA from 11 species in nine families. A subset of the DNA extracts was tested in more detail and proved to be highly suitable for AFLP analysis.

The effects of climate on the growth and physiology of tropical rainforest trees

Tropical rainforests account for more than a third of global net primary production and contain more than half of the global forest carbon. Though these forests are a disproportionately important component of the global carbon cycle, the relationship between rainforest productivity and climate remains poorly understood. Understanding the link between current climate and rainforest tree stem diameter increment, a major constituent of forest productivity, will be crucial to efforts at modeling future climate and rainforest response to climate change. This work reports the physiological and stem growth responses to micrometeorological and phenological states of ten species of canopy trees in a Costa Rican wet tropical forest at sub-annual time intervals. I measured tree growth using band dendrometers and estimated leaf and reproductive phenological states monthly. Electronic data loggers recorded xylem sap flow (an indicator of photosynthetic rate) and weather at half-hour intervals. An analysis of xylem sap flow showed that physiological responses were independent of species, which allowed me to construct a general model of weather driven sap flow rates. This model predicted more than eighty percent of climate driven sap flow variation. Leaf phenology influenced growth in three of the ten species, with two of these species showing a link between leaf phenology and weather. A combination of rainfall, air temperature, and irradiance likely provided the cues that triggered leaf drop in Dipteryx panamensis and Lecythis ampla. Combining the results of the sap flow model, growth, and the climate measures showed tree growth was correlated to climate, though the majority of growth variation remained unexplained. Low variance in the environmental variables and growth rates likely contributed to the large amount of unexplained variation. A simple model that included previous growth increment and three meteorological variables explained from four to nearly fifty percent of the growth variation. Significant growth carryover existed in six of the ten species, and rainfall was positively correlated to growth in eight of the ten species. Minimum nighttime temperature was also correlated to higher growth rates in five of the species and irradiance in two species. These results indicate that tropical rainforest tree trunks could act as carbon sinks if future climate becomes wetter and slightly warmer. ^

Derechos humanos y libertad de expresion en el contexto del TLC

La libertad de expresión, entendido como el derecho de informar y ser informado son parte esencial de nuestros derechos humanos. Cualquier circunstancia que limite esos derechos atropella la dignidad humana. Existe una abundante y explícita normativa de derechos humanos que buscan garantizar el libre ejercicio de la comunicación: instrumentos internacionales y regionales y una reiterada jurisprudencia. El derecho humano de libertad de expresión es entendido como el derecho a expresarse, buscar y recibir información. Censurar o limitar ciertas publicaciones o establecer mecanismos que restringen el acceso a información pública son formas sutiles de atropellar esos derechos. El recurrir a figuras penales como el desacato o insulto a funcionarios o delitos contra el honor podrían activarse y tornarse amenazantes para el que ejerce el periodismo. Esta sería una forma de silenciar cualquier cuestionamiento a figuras públicas en detrimento de un principio fundamental de toda democracia. Suerte parecida corre el derecho de reconocer el secreto profesional del periodista y la expresión del pluralismo. De hecho que al igual que en otros campos como el laboral, salud, alimentación, el derecho a un ejercicio digno de la comunicación también es susceptible de verse amenazado. Abstract An essential aspect of our human rights is that we have freedom to express ourselves and to be informed. There are wide and specific human rights regulations, which seek to guarantee the freedom of expression: international and national instruments and reiterative jurisprudence. Two main principles that set the foundation for freedom of expression are liberty to express oneself and liberty to obtain and search for information. Censuring or limiting certain publications, as well as setting up mechanisms to restrict people’s access to public information, are subtle ways of threatening these rights.

CONSERVACIÓN PREVENTIVA DE DOCUMENTOS

Por su carácter constitutivo y al estar frecuentemente expuestos a factores y mecanismos de alteración, los documentos en soporte de papel sufren constantes cambios en su composición física y funcional, lo cual pone en peligro la información consignada en ellos. En países de clima tropical como el nuestro, este riesgo es mucho mayor, ya que las condiciones ambientales propician la aparición más frecuente de agentes adversos a la estructura molecular del papel mismo.Por consiguiente, los funcionarios a cargo de la producción, organización y facilitación de documentos públicos y privados, así como quienes conservan materiales de índole particular, tienen la responsabilidad de crear condiciones ambientales, estructurales y administrativas propicias, con el objeto de garantizar la perdurabilidad de sus acervos documentales para las futuras generaciones.Dado que la cultura costarricense usualmente se enfoca en “apagar el fuego” cuando el incendio está en pleno desarrollo, es que se considera prioritario impulsar y propiciar políticas preventivas para que los documentos que se produzcan en las instituciones públicas, surjan y se conserven en condiciones óptimas para su conservación permanente. 

CONTROL DOCUMENTAL SOBRE GRUPOS ÉTNICOS INDÍGENAS COSTARRICENSES: 1980-2003

En Costa Rica se ha hecho poco por realizar el control documental nacional sobre grupos étnicos indígenas, esto puede ser tipificado como una debilidad, dos obras son el universo de fuentes de referencia.La necesidad de contar con el control documental sobre/de grupos étnicos indígenas costarricenses entre 1980-2003, es el propósito que persiguió esta investigación, además brindar un aporte de valor histórico, cultural y científico a aquellas personas interesadas en la temática indígena costarricense.Este control documental pretende agrupar la temática en estudio de dicho período. Es importante mencionar que en Costa Rica existen controles documentales sobre otras temáticas, no así de la temática indígena.Este control facilitará el rescate de la cultura indígena costarricense, es un aporte al control documental nacional y universal, contiene documentos de los años comprendidos entre 1980-2003, el mismo es fundamental para el acceso y disponibilidad de la información que forma parte de la actividad propia del profesional en bibliotecología, el cual se realiza dé acuerdo con las normas y criterios establecidos a nivel nacional e internacional. Además servirá y contribuirá como antecedente para futuros controles documentales sobre esta temática.
