Abstract:

Background: In 2016, 459 dentists were registered in French West Indies and French Guyana. They represent 10% of French clinicians but they work in an environment very different from continental France. The aim of this study was to describe dental implantology practices among dentists in Guadeloupe, Martinique, and French Guyana. Materials and methods: A cross-sectional study, with questionnaires sent by email, was conducted from November 2016 to January 2017. Results: 116 practitioners answered. Respondents were all general practitioners, except two dentists who practiced only surgical procedures (not specialists). Implant surgeries were provided by 50% respondents and soft-tissue or hard-tissue grafting were provided by 34.5% of the sample. Prosthodontic procedures were carried out by 62.9% respondents. At last, 34.5% of the sample were not involved in implant services. Discussion: The proportion of dentists who performed implant procedures was similar to that reported in other international studies and French survey. The percentage of dentists not involved in implant dentistry still significant and the most frequently reported barriers were the expense of treatment, patient's difficulties to afford the treatment and the lack of knowledge. Conclusion: The practice of implant dentistry is widespread in French West Indies and French Guyana. Dental implant use was not different between clinicians of Guadeloupe, Martinique, and French Guyana. The number of dentists who received local implant training was lower in French Guyana.

Abstract:

The water scavenger beetle genus Chasmogenus Sharp, 1882 is reviewed in northeastern South America using an integrative approach that combines adult morphology and molecular data from the gene cytochrome c oxidase I (COI). Eighteen new species are described: Chasmogenus acuminatussp. nov. (Brazil, French Guiana, Guyana, Suriname), C. ampliussp. nov. (Venezuela), C. berbicensissp. nov. (Guyana), C. brownsbergensissp. nov. (Suriname), C. castaneussp. nov. (Venezuela), C. clavijoisp. nov. (Venezuela), C. cuspifersp. nov. (Venezuela), C. flavomarginatussp. nov. (Venezuela), C. gatosp. nov. (Venezuela), C. guianensissp. nov. (Suriname, Guyana), C. ignotussp. nov. (Brazil), C. ligulatussp. nov. (Suriname), C. lineatussp. nov. (Venezuela), C. pandussp. nov. (Brazil, French Guiana, Suriname), C. schmitssp. nov. (Suriname), C. sinnamarensissp. nov. (French Guiana), C. tafelbergensissp. nov. (Suriname), and C. undulatussp. nov. (Guyana). We found genetic support for an additional new species in Guyana which is currently only known from females that we refer to as Chasmogenus sp. C. We examined the holotypes of the four species previously known from the region, and found that C. occidentalis García syn. nov. and C. yukparum García syn. nov. are conspecific with C. bariorum García, 2000 and are synonymized with that species, which is here redescribed. We redescribe C. australis García and expand the range of this species to include northern Brazil, Guyana, and French Guiana. All species are aquatic, with most being associated with forested streams and forest pools. Of the 21 species, more than half (11) are only known from a single locality indicating the genus may have many more micro-endemic species yet to be discovered in the region. Characters of the male genitalia are essential for confirming the identity of some species, consequently it is not always possible to make positive identifications of unassociated female specimens based on morphology alone. Habitus images are provided as well as a revised key to the genus for northeastern South America.

Abstract:

The colonization of French Guyana encountered serious difficulties on the part of the administering power due to the impossibility of recruiting white labor. The existing documentation in the overseas archives of Aix-en-Provence and Nantes show the infeasibility of sending Europeans to repopulate Guyana. Before which the French government considered the possibility of resorting to peasants from Madeira and the Canary Islands who were better adapted to the harsh climatic conditions of the colony.

Abstract:

The ongoing treatments for the Flora of the Guianas (Guyana, Surinam, and French Guiana) and the monographic study of the tribe Sipaneeae prompted a revision of Neobertiera, discovering the distylous condition of this genus, and three undescribed species, one probably restricted to Guyana, and two probably restricted to French Guiana. Because of these novel observations and the different kinds of inflorescence of the newly described species, a generic description, with yet another amendment, a key to the species, illustrations, and material examined are presented.

Abstract:

Since its formation in 1831, the French Foreign Legion has traditionally defended French interests in the overseas regions. During its nearly two centuries of existence, it was primarily involved in the conquest and protection of colonial territories in Africa but was also deployed many times on the Asian and American continents. In the latter region, the Foreign Legion has been active since 1973, mainly in the European space centre in French Guyana, protected by the soldiers of the 3rd Foreign Infantry Regiment. The Guyana Space Centre, currently the largest spaceport of the European Union, was established in 1964 in French Guyana near the city of Kourou, making it ideal for launching space rockets due to its proximity to the Equator. The space centre, originally run by the French state, has been shared with other European Space Agency countries since 1975, launching European satellites from an area more than 7,000 kilometers from Europe. Among other projects, they enable the operation of the Union’s satellite navigation system, Galileo. For all these reasons, the protection of the space centre is a priority task, which the Foreign Legion has been effectively providing for almost 50 years with tools and methods that have been constantly renewed. The aim of this paper is to present this activity and its impact on the region and, more broadly, on the scientific and geopolitical situation in Europe.

Abstract:

A new species of Charinus Simon, 1892 is described from French Guyana, raising the number of species in the genus to48 (27 for the Neotropical region and 19 for South America). Charinus bromeliaea sp. n. is distinguished from the otherspecies in the genus by morphological characteristics and unique ecology. Adapted to live in Achmea bromeliads on gran-ite inselbergs, this species is an interesting addition to the wide range of habitats Charinus species are found in. This is also the first record of the genus from French Guyana and this record extends the geographic distribution of the genus.

(Venezuela), N. yorasp. nov. (Peru). One new synonym is proposed: N. carmona (Short, 2005) syn. nov. was determined to be a junior subjective synonym of N. chaquensis (Fernández, 1982). Novochares inornatus (d’Orchymont, 1926) is considered incertae sedis. Updated distributions and new records are provided for most previously described species in the genus. Novochares sallaei (Sharp, 1882) is considered native to the USA (Florida) and not an introduced species as previously suggested. Novochares now contains 52 species and spans the entire Neotropical region from Mexico to Argentina, including the Caribbean islands.

Abstract:

Devant l'importance des enjeux en termes de climat, de santé publique ou d'activités économiques, la brume de poussières fait l'objet d'un intérêt croissant avec de nombreuses recherches menées depuis maintenant plusieurs décennies. Les régions ultramarines françaises des Antilles et de la Guyane sont particulièrement exposées aux poussières désertiques issues du Sahara. Celles-ci sont composées de divers éléments, notamment minéraux, pouvant favoriser les impacts sanitaires néfastes de certains virus et bactéries. La brume de poussières revêt un intérêt particulier dans la prévision opérationnelle, en raison de son rôle sur la convection atmosphérique, dont la compréhension, l'observation et la modélisation nécessitent d'être approfondies. Nous mettons en exergue la fréquence de ce phénomène aux Antilles et en Guyane, dépendant majoritairement de la variabilité naturelle du climat et des oscillations climatiques, mais pouvant également être en partie lié à l'impact de certaines activités humaines (comme la désertification). Given its importance in terms of climate, public health or economic activities, dust haze is subject to a growing interest with a lot of research carried out for several decades now. The French overseas regions of the Antilles and Guyana are particularly exposed to desert dust from the Sahara, which carries various elements, in particular minerals, and can favour the harmful health impacts of certain viruses and bacteria. Dust haze is of particular interest in operational forecasting because of its role in convection, which requires further understanding, observation and modeling. Through this article, we highlight the frequency of this phenomenon in the French West Indies and Guyana, depending mainly on the natural variability of climate and the climate oscillations, but which can also be partly linked to the impact of certain human activities (such as desertification).

Abstract:

The genusRhyncholeptaBergroth, 1911 (Hemiptera: Heteroptera: Pentatomidae: Pentatominae: Chlorocorini) is redescribed and five species-group taxa are recognized, keyed, their diagnostic characters illustrated, and the distribution reviewed. Among the five taxa, two species and one subspecies are recognized as new:RhyncholeptagrandicallosagrandicallosaBergroth, 1911 (Brazil, Ecuador, French Guiana, Guyana, Peru, Suriname),Rhyncholeptagrandicallosacentroamericanasubsp. n.(Belize, Costa Rica, Guatemala, Mexico, Panama),Rhyncholeptahenryisp. n.(French Guiana),RhyncholeptameinanderiBecker & Grazia-Vieira, 1971 (Bolivia, Brazil, Ecuador, Peru), andRhyncholeptawheelerisp. n.(Guyana). The structure of the male genital capsule was found to be the only reliable character for identifying species-group taxa. For this reason, a simultaneous application has been submitted to the International Commission on Zoological Nomenclature to set aside the non-informative female lectotype ofRhyncholeptagrandicallosagrandicallosaand replace it with the male neotype suggested herein. Based on the available label data and our field experience, most of the specimens were collected by various types of light traps in or near dense forests. Adults can be collected throughout the year.

Full text

Abstract:

Litter falls and their contributions to soil nutriments were measured in five distinct facies of a mangrove in French Guyana. These facies were characterized by their distance from the sea, their floral composition (Laguncularia racemosa (L.), Avicennia germinans (L.) Stearn, Rhizophora spp.), and their structural features. Data were analyzed according to facies and to species for litters, as well as to seasons for the nutriments. This mangrove produced respectively 8.8 and 8.7 t·ha1·year1 of litter at the pioneer and senescent stages submitted to strong environmental constraint and 12.5 and 12.6 t·ha1·year1 for young and mature stages where developmental conditions are optimum. Nitrogen and carbon inputs were estimated to 1.3 × 102 and 6.4 t·ha1·year1, respectively. Litter appeared rich in phosphorous, corresponding with the high concentrations characterizing the sediments. For a given species, magnesium and calcium concentrations were constant between facies, whereas potassium and sodium concentrations varied according to the distance from the sea. Differences were perceived between species for all nutriments except sodium. Results are discussed in relation with the ecophysiological characteristics of the mangrove trees and the specific sedimentology of Guyana coast and are replaced in the perspective of an improved knowledge of the carbon and mineral balances in tropical coastal ecosystems.Key words: mangrove, French Guyana, litter, carbon balance, mineral nutriments, spatial variations.[Journal translation]

Abstract:

Abstract— Neocalyptrocalyx (Capparaceae) is a Neotropical genus that comprises eleven species that occur in the lowlands of Brazil, Guyana, French Guyana, Suriname, Venezuela, and Ecuador. The study of collections deposited in herbaria added to field observations allowed the recognition of three species as new to science, and those are formally presented here: Neocalyptrocalyx aequatoriensis, known only from eastern Ecuador, Neocalyptrocalyx atlanticum from the Atlantic Forest, and Neocalyptrocalyx polycataphyllus from the Brazilian Amazonia. Neocalyptrocalyx aequatoriensis represents the new westernmost boundary for the genus and the first generic record for Ecuador. We present diagnoses, descriptions, ink illustrations, field photos, distribution maps, notes on ecology, habitat, morphology, phenology, conservation status, and a key to distinguish the new species from related species.

Full text

Abstract:

The first new species of rhinatrematid caecilian in more than 50 years, Rhinatrema shiv sp. nov., is described from Guyana. The type series of 10 specimens differs from the only other species in the genus, R. bivittatum, in having a longer tail, different colour pattern, more acuminate and relatively shorter head, and in several features of the skull and mandible including dentition. Sequence data for 1572 aligned base pairs of mitochondrial DNA are > 15% different between the two species. Rhinatrema shiv is known only from Guyana, and R. bivittatum from French Guiana and far northeastern Brazil. The only reported specimen of the genus from Suriname is not clearly referable to either of the named species.

Recent study of the water scavenger beetle subfamily Acidocerinae in the Neotropical region has uncovered numerous undescribed species that are not able to be placed in existing genera. Here, we describe three new genera to accommodate 17 of these new species from South America: Aulonocharesgen. nov. for Aulonochareslingulatussp. nov. (French Guiana, Suriname), Aulonocharesnovoairensissp. nov. (Brazil), and Aulonocharestubulussp. nov. (Brazil, Guyana, Suriname, Venezuela); Ephydrolithusgen. nov. for Ephydrolithushamadaesp. nov. (Brazil), Ephydrolithusminorsp. nov. (Brazil), Ephydrolithusogmossp. nov. (Brazil), Ephydrolithusspiculatussp. nov. (Brazil), and Ephydrolithustelisp. nov. (Brazil); and Primocerusgen. nov. for Primoceruscuspidissp. nov. (Venezuela), Primocerusgigassp. nov. (Venezuela), Primocerusneutrumsp. nov. (Guyana, Suriname, Venezuela), Primocerusocellatussp. nov. (Venezuela), Primoceruspetilussp. nov. (Brazil), Primoceruspijiguaensesp. nov. (Venezuela), Primocerusmaipuresp. nov. (Venezuela), Primocerussemipubescenssp. nov. (Guyana), and Primocerusstriatolatussp. nov. (Suriname). The genus Ephydrolithusgen. nov. is currently known to be restricted to seepages in the mountainous regions of the Brazilian Shield. Aulonocharesgen. nov. and Primocerusgen. nov. are both currently only known from the Guiana Shield, though widespread in that region where they are associated with streams and seeps. We present differential diagnoses, maps, habitat details, and illustrations of all new genera and species here described.

Full text

Abstract:

The authors present the French concept of a mobile neurosurgical unit (MNSU) as used to provide specific support to remote military medicosurgical units deployed in Africa, South America, Central Europe, and Afghanistan. From 2001 to 2009, 15 missions were performed, for 16 patients. All but 3 of these missions (those in Kosovo, French Guyana, and Afghanistan) concerned Africa. Eleven patients were French soldiers, 3 were civilians, and 2 were Djiboutian soldiers. The conditions that MNSUs were requested for included craniocerebral wounds (2 cases), closed head trauma (7 cases), spinal trauma (5 cases), and spontaneous intracranial hemorrhage (2 cases). In 5 of the 16 cases, neurosurgical treatment was provided on site. All French soldiers and 2 civilians were evacuated to France. The MNSU can be deployed for timely treatment when some delay in neurosurgical management is acceptable.

Full text

Abstract:

The fungal pathogen Batrachochytrium dendrobatidis (Bd) which causes that amphibian disease chytridiomycosis is expanding its worldwide range from an Asian origin, infecting amphibians in a growing number of countries. Modelling the potential range of this amphibian pathogen using environmental variables and presence data could advance our understanding of at-risk areas and species in locations with limited surveillance to date. We used a species distribution model to assess Bd habitat suitability in the three Guiana’s (Guyana, Suriname, and French Guiana) in South America. The model output showed that all three countries have substantial areas where Bd could grow and proliferate, and maximum temperature of the warmest month was the top predictor of suitable Bd habitat, inversely correlated with modeled Bd occurrence. Predicted Bd infection areas in Guyana and French Guiana were large and localized whereas possible sites in Suriname were more scattered throughout the country. The areas projected as potential suitable in Suriname were mostly high elevation regions. These results could help inform efficiencies for development of a proactive monitoring program that could alert managers of novel Bd outbreaks for focused mitigation actions to forestall the spread of this amphibian disease.

Abstract:

As rehabilitation efforts in Guyana are recent, there is little information on the effect of different ecological rehabilitation protocols for Guyana’s mining sites on biogeochemical cycles and mercury mobility. This study was conducted to assess the impact of different ecological restoration protocols on soil quality with the use of soil microbial indicators and by estimating the mercury mobility. We sampled soil from six rehabilitated mining sites in French Guyana with different ecological restoration procedures. We carried out measurements of enzymatic activities and an analysis of mercury environmental speciation to assess its potential toxicity according to a mobility gradient. The results obtained in this study show that the rehabilitation of mining sites has been carried out in a heterogeneous manner and soil quality is very variable, even in nearby sites. Sites that have been rehabilitated with fabaceous species have positive soil quality indicators. In addition, the results highlight a change in mercury mobility that is 82.1% correlated after co-inertia analysis with soil texture properties, which also confirms a direct effect of rehabilitation on mercury mobility. The non-restored sites had a much higher potential of mercury mobility and toxicity than the sites where ecological restoration was successful. These results highlight the positive effect of controlled rehabilitation and ecological restoration on microbiological activities and the potential toxicity of mercury.

Abstract This article explains how safety investigators with the French Bureau of Enquiry and Analysis for Civil Aviation Safety (BEA) used chip-level recovery procedures to retrieve recorded flight data that helped them piece together the events that led up to helicopter accident that recently occurred in French Guyana. The recovered data along with eyewitness accounts and findings from an assortment of tests indicated that the failure of a capacitor filtering the output of a current generator inside the engine fuel automatic regulation system obliged the pilot to control fuel regulation manually. Although other factors were involved, as the article explains, the capacitor failure played a major role in the crash.
