Human-Environment Observatory (OHM) Oyapock Guyane, France © D. Davy © D. 0 40mi TERRITORY FRENCH Cayenne The study area stretches along both banks of the Oyapock river, a natural border GUYANA between French Guiana and Brazil. The OHM is located entirely within the tropical rainforest, and includes the communities of Ouanary, Saint-Georges-de- St-Georges-de-l’Oyapock l’Oyapock Camopi on the French side, and the vast community of Oiapoque on Oïapoque the Brazilian side. Almost half of this area is in French and Brazilian conservation Camopi areas (Guiana Regional Natural Park, Guiana Amazonian Park, Cabo Orange National Park and Tumucumaque National Park). Sparsely populated, this area is Oyapock BRAZIL Amapá in the process of being opened up to the outside world with the recent opening of two roads that reach all the way to the river. The construction of a transborder CREATION river bridge should further accelerate these changes. July 2008 SOCIAL-ECOLOGICAL FRAMEWORK Tropical forest socio-ecosystem organised around the Oyapock river that forms the boundary between France (French Guiana) and Brazil (state of Amapá) and characterised by relative isolation. DISRUPTING EVENT Construction of a bridge over the Oyapock and opening up of the area to external influences. KEY TOPICS © D. Davy • Social economic impact • Environment, health • Biodiversity • Anthropisation processes © D. Davy SOCIAL-ECOLOGICAL ISSUES Construction of a bridge between the communities of Saint-Georges-de-l’Oyapock and Oiapoque constitutes a very significant modifying event for the area. This infrastructure does not necessarily bring the neighbouring populations closer together, since they have long used the river to meet and exchange; however, the bridge could well strengthen the area as a transit and control zone between Brazil and French Guiana, with countless consequences in terms of mixing of the populations, pressure on the land and forests, impacts on the river, etc. The OHM aims to identify and monitor the key processes which will influence the human population and its environment, their interactions and their dynamics. © A.

Since the identification of Zika virus (ZIKV) in Brazil in May 2015, the virus has spread throughout the Americas. However, ZIKV burden in the general population in affected countries remains unknown. Methods. We conducted a general population survey in the different communities of French Guiana through individual inter- views and serologic survey during June–October 2017. All serum samples were tested for anti-ZIKV immunoglobulin G antibodies using a recombinant antigen-based SGERPAxMap microsphere immunoassay, and some of them were further evaluated through anti-ZIKV microneutralization tests.

Historical Setting of the Guianan Plant Heritage The Guianas are embedded high in the green shoulder of northern South America, an area once known as the "Wild Coast". They are the only non-Latin American countries in South America, and are situated just north of the Equator in a configuration with the Amazon River of Brazil to the south and the Orinoco River of Venezuela to the west. The three Guianas comprise, from west to east, the countries of Guyana (area: 83,000 square miles; capital: Georgetown), Surinam (area: 63, 037 square miles; capital: Paramaribo) and French Guiana (area: 34, 740 square miles; capital: Cayenne). Perhaps the earliest physical contact between Europeans and the present-day Guianas occurred in 1500 when the Spanish navigator Vincente Yanez Pinzon, after discovering the Amazon River, sailed northwest and entered the Oyapock River, which is now the eastern boundary of French Guiana.

The aim of the present study was to describe HIV knowledge, risk and the level of stigma among inhabitants of this border area. Methods: A cross-sectional study was conducted among 621 inhabitants over 18 years of age in the border cities of Saint-Georges-de-l’Oyapock in French Guiana and Oiapoque in Brazil. It was conducted between October 2017 and February 2018. An anonymous standardized questionnaire was filled out by culturally-trained mediators, then analyzed using STATA 12. Results: Almost half (45.9%) of the individuals had a low education level. Participants whose native language was Portuguese or French demonstrated better HIV knowledge than other populations, notably native Amerindian and creole-speaking people. HIV risk behavior was more frequent in men and in younger age groups. People with good HIV knowledge reported having performed more HIV tests in the last year than participants with poor knowledge. The stigma level was high and reported in 74.8% of respondents.

Gm and Km Allotypes in Wayampi, Wayana and Emerillon Indians from French Guiana
L ANNALS OF HUMAN BIOLOGY, 1994, VOL.'.21, NO. 4, 335-345 Gm and Km allotypes in Wayampi, Wayana and Emerillon Indians from French Guiana J. M. DUGOUJONP,E. GUITARDP,M. T. SENEGAS?,P. GRENANDSand E. BOIS* TCentre de Recherches sur le Polymorphisme Génétique des populations humaines, Toulouse, France $Département Société, Urbanisme, Développement, Paris, France *Unité de Recherches d'Epidémiologie Génétique, Paris, France Received 16 April 1993; revised II November 1993 Summary. We have studied 506 Amerindians from three French Guiana groups: 194 Wayampi, living in Trois-Sauts, and 100 in the Camopi area; 47 Emerillon also living in the Camopi area and 165 Wayana on the Litani and Maroni rivers. All samples were tested for Glm(1,2,3,17), G3m(5,6,10,11,13,14,15,16,21,24,28) and Km(1) by the classical method of hemaglutination inhibition. The phenotype and haplotype distributions are presented and have been subjected to factorial correspondence analysis. Two Gm haplotypes are common: Gm1*37;21,28,and Gm1,2,17;21,28,but with an important variation in frequency. A rare haplotype, probably the result of a genetic anomaly: Gm1,17;21R>28,is frequent in the Emerillon (17%). These populations show no evidence of Black or Caucasian admixtures. 1. Introduction The allotypic markers of human immunoglobulins (Ig) are inherited differences located on the heavy chains of IgG (Gm), IgA (Am), IgE (Em) and light chain Kappa (Km). Each epitope is restricted to one of the IgG (IgGl, IgG2 and IgG3) or IgA (IgA2) subclasses and found on the constant regions (CHI, CH2, or CH3 domains).

French Reaction to the Menace from Cabanos and Bonis Within the Litigious Territory Between Brazil and French Guiana (1836-1841)1
125 French reaction to the menace from Cabanos and Bonis within the litigious territory between Brazil and French Guiana (1836-1841)1 Reação francesa às ameaças de Cabanos e Bonis no território litigioso do Amapá (1836-1841) DOI: http://dx.doi.org/10.1590/2236-463320161408 Débora Bendocchi Alves Instituto de História Ibérica e Latinoamericana (IHILA) Faculdade de História da Universidade de Colônia, Colônia, Alemanha [email protected] Abstract: This article will analyze an historical episode that occurred between 1836 and 1841 during the French occupation of the disputed territory located between Brazil and French Guiana. I intend to consider two regional factors that influenced the decision of both the Cayenne Government and the metropolitan government to build military forts in the region. Such factors are the Cabanagem and the attempts of black Bonis to settle in Lower Oiapoque. I will go on to show that the French withdrawal from Amapá Lake in 1840, but not from the post on the right bank of the Oiapoque River, was due not only to international and diplomatic factors but also had regional causes. Notwithstanding the French government's interests in expanding the territory of its South American colony, I want to draw attention to the threats - real or fictitious - of Cabanos, from Brazil, and black Bonis, from Dutch Guiana. 1 This article forms part of a research project funded by Gerda Henkel Foundation (Germany) about the region of the French-Brazilian Boarding between 1840-1900. It is a revised and extended version of my participation at the ANPUH 2015 XXVIII National History Symposium, held in Florianópolis.

Conviviality After the Inauguration of the Oyapock River Bridge
LabEx DRIIHM Dispositif de Recherche Interdisciplinaire sur les Interactions Hommes-Milieux CNRS - Observatoires Hommes-Milieux - Investissements d'avenir Projet de recherche Building bridges: Conviviality after the inauguration of the Oyapock River Bridge Session 2017 Project type Projet OHM OHM(s) involved OHM Oyapock Keywords Brazil French Guiana Oyapock River Bridge Ethnography Anthropologie, Sociologie The inauguration of the Oyapock River Bridge has been delayed several times for a variety of reasons. Now that the final constructions on the Brazilian side are underway, the opening is expected to take place in the course of the year 2017. Yet what happens once the bridge opens? While most politicians have high hopes for regional cooperation, the majority of the local residents are more skeptical, worrying about unequal rights to border crossings (with Brazilians being disadvantaged) and the loss of jobs (particularly those related with fluvial transportation). The proposed project aims to go beyond these speculations by studying the immediate aftermath of the inauguration of the Oyapock River Bridge. How will the opening of the bridge impact on the everyday life of the people living in Saint-Georges, Oiapoque and the larger region? From an ethnographic perspective, this project will supplement research already carried out both by OHM Oyapock researchers and by the author himself. Leader Fabio Santos Fabio Santos is a PhD Researcher at the International Training Group "Between Spaces" (Freie Universität Berlin). He holds an M.A. in Sociology from Freie Universität Berlin and a B.A. in European Ethnology and Cultural History and Theory from Humboldt-Universität Berlin. His areas of interest are postcolonial studies, the sociology of space, ethnographic methods, and questions of conviviality..

DELPRETE1* 1Herbier de Guyane, Institut de Recherche pour le Développement (IRD), UMR AMAP, Boite Postale 165, 97323 Cayenne Cedex, French Guiana, France; e-mail: [email protected] *Author for correspondence Abstract Utricularia julianae, a new species from the savannas near the Oyapock River, French Guiana, is here described and illustrated. The new species is most similar to U. tenuissima, from which it can be easily distinguished by the leaves and stolons apparently lacking (vs. leaves few and on the stolons, the stolons few or lacking, in U. tenuissima), traps ellipsoid, 0.3 mm long, with 4–5 capilliform appendages (vs. ovoid, 0.3–0.8 mm long, with 1 dorsal and 2 ventral slender appendages), corolla upper lip limb deeply bilobed (vs. broadly ovate to round), spur saccate, perpendicular to the lower lip (vs. spur narrowly cylindrical, parallel to the lower lip), among other characters. In addition, the capsules of U. julianae and U. tenuissima are unique within the genus, by being very narrowly ovoid, dehiscing by a single longitudinal slit, and with a placenta projecting outside the dehisced capsule. On the basis of their numerous morphological similarities and their peculiar capsule shape and dehiscence, the new species is tentatively placed within sect. Martinia, which P.
