Abstract: Marine biodiversity in French Guiana is strongly influenced by the amagon River waters of the river Amazon, which constitute a major structuring factor for the estuarine, coastal, and shelf marine ecosystems. Moreover, the marked seasonal and interannual variabilities play important roles in the stability or fluctuations in the environmental parameters that influence biodiversity at the ecological, population, and genetic levels. Previous and ongoing studies of the marine and littoral biota relate mostly to commercial marine species, protected species in danger of extinction and, specially, to the biodiversity and functioning of local coastal and littoral ecosystems such as estuaries, mudflats, sandy beaches and, particularly, littoral mangroves. A more integrated approach involving local, regional, and international scientific collaboration is needed for a better assessment and understanding of marine biodiversity. Such studies would benefit from international cooperation that would allow the gathering of new information and the comparison of previous data, the organization of common oceanographic surveys, the homogenisation of analytical protocols, and also favour the exchange of scientists and postgraduate students for a real transfer of ideas, techniques, and know-how. Moreover, research on the comparative biodiversity of analogous littoral and marine ecosystems in different parts of South America would allow a more accurate estimate of marine biodiversity on a continental scale. La biodiversidad marina en la Guyana Francesa está fuertemente influenciada por los aportes amazónicos, los cuales constituyen un factor estructurante de los ecosistemas estuarianos, costeros y de plataforma continental. Además, debido a las cambiantes condiciones meteorológicas y oceanográficas, la variabilidad estacional e inter-anual puede jugar un rol importante en la estabilidad o la modificación de los parámetros medio-ambientales que afectarían la biodiversidad ecológica, poblacional y genética de los ecosistemas locales. Los estudios llevados a cabo sobre la biología de las especies marinas y litorales se refieren principalmente a especies de interés comercial, especies protegidas en peligro de extinción, y sobre todo a las características del funcionamiento de ciertos ecosistemas costeros y litorales característicos como los estuarios, bancos de fango, playas de arena, y sobre todo los manglares. La idea de estudios o series de estudios mejor coordinados entre sí a nivel regional e internacional, emerge como una necesidad para una mejor estimación y comprensión de
Symbolic legacies of slavery in Guyana
Alvin O. Thompson
New West Indian Guide , 2008,
Abstract: Focusses on the commemoration and symbolic functions of the slavery past in the Americas, with a particular focus on Guyana. Author explains that while symbolic representations of the legacies of slavery increased in the Americas since the 1960s, the nationalist government under Forbes Burnham since 1970 went further in using the slavery past as its ideological foundation. He discusses how this relates to Guyana's history and ethnic development of 2 main, often opposed groups of African- and Indian-descended groups, calling on their respective slavery or indenture past in emphasizing their national significance. He further describes slavery-related symbolic representations promoted under Burnham, specifically the 1763 slave revolt led by Cuffy, presented as first anticolonial rebellion aimed at liberation, and as a precursor to the PNC government, and other slave rebellions and rebels, such as led by Damon in 1834. He points out how some Indian-Guyanese found that Indian heroes were sidelined in relation to these. Author then describes how the annual commemoration of Emancipation Day continues to refer to the martyrdom of these slave rebels, along with other discursive connections, such as regarding reparations. He also pays attention to the activities of nongovernmental organizations in Guyana up to the present in commemorating the slavery past, often with broader African diaspora connections.
Identification and Classification of Earthworm Species in Guyana
Abdullah Adil Ansari,Preeta Saywack
International Journal of Zoological Research , 2011,
Abstract: Earthworms are very important organisms, they are both environmentally and economically beneficial and hence their correct identification and classification is very vital. Taxonomy aims to classify organisms based on their similarities and differences. The present study was carried out during the year 2006-2007 at University of Guyana, Georgetown focusing on identification and classification of local earthworm species of Guyana and comparison with a known non-native species (California red). The earthworms were collected (using hand sorting method), cultured and then carefully examined (worms were washed with water, preserved in 10% formalin solution). The two species studied were identified based on their external morphology and internal anatomy as well as their ecological features. The California red earthworm was grouped under the family Lumbricidae and identified as Eisenia foetida, while the local species was grouped under the family Eudrilidae and identified as Eudrilus eugenia.

Abstract: Se realiza un estudio retrospectivo de la incidencia de las fracturas mandibulares en relación con el total de las fracturas maxilofaciales atendidas en la República de Guyana durante el a o 2001 debido a su alta presentación en nuestro quehacer diario, con el objetivo de determinar el comportamiento de estas lesiones y su relación con la edad, sexo, etiología y área mandibular vulnerable. Las variables estudiadas fueron sexo, edad, causa de la fractura y región afectada. Las fracturas mandibulares ocuparon el 56,6 % del total de fracturas maxilofaciales y fue más frecuente en los hombres ( 89,5 %). Los grupos etáreos de mayor incidencia fueron de 25 a 34 y de 35 a 44 a os, con el 30,6 %. La causa más común de fracturas mandibulares fue la agresión personal ( 68,6 %) y la región anatómica más afectada el ángulo mandibular ( 67,4 %). A retrospective study of the incidence of mandibular fractures in relation to the total of maxillofacial fractures attended in the Republic of Guyana during 2001 was conducted taking into account its high ocurrence in our daily practice in order to determine the behavior of these injuries and its connection with age, sex, etiology and vulnerable mandibular area. The variables studied were sex, age, cause of the fracture and affected region. The mandibular fractures accounted for 56.6 % of the total of maxillofacial fractures and they were more frequent in men (89.5 %). The age groups with the highest incidence were from 25 to 34 and from 35 to 44 years old, accounting for 30.6 %. The most frequent cause of mandibular fracture was personal aggression (68.6 %) and the commonest anatomical region was the mandibular angle (67.4 %).

Abstract: Since our last report in 2003, we document the discovery of an additional seven species of Inocybe from Dicymbe (Fabaceae) forests of Guyana in northeastern South America. Of these, five are described as new: I. enigmatica, I. lepidotella, I. magnifolia, I. marginata, and I. rhodella. Two additional species described originally from Brazil and Venezuela, I. amazoniensis and I. lasseri, respectively, are reported as new records for Guyana. This raises the number of Inocybe species reported from Guyana to eleven. Molecular identifications of ectomycorrhizal root tips of species of Dicymbe and Aldina (Fabaceae) match five of the known Inocybe species from Guyana. An additional eight Inocybe ITS sequences distinct at the species level were detected from ectomycorrhizal root tips of Fabaceae in Guyana but at present match no known morphological species represented in regional or global sequence databases. A revised key to species of Inocybe from Guyana is presented together with illustrations of new taxa. Data from examination of types of I. amazoniensis and I. matrisdei are presented, as well as supplementary reports of I. epidendron and I. pulchella, both originally described from Guyana. Desde nuestro último reporte en 2003, documentamos el descubrimiento de siete especies adicionales de Inocybe en bosques de Dicymbe (Fabaceae) en Guyana, en el norte de Sudamérica, de las cuales cinco son especies nuevas: I. enigmatica, I. lepidotella, I. magnifolia, I. marginata e I. rhodella, dos son especies descritas originalmente de Brasil y Venezuela: I. amazoniensis e I. lasseri, respectivamente y son nuevos registros para la región. Esto eleva el número de especies de Inocybe registradas para Guyana a once. Identificaciones moleculares de puntas de raíces ectomicorrizadas de Dicymbe y Aldina (Fabaceae) coinciden con cinco de las especies de Inocybe conocidas de Guyana. Adicionalmente se detectaron ocho secuencias de ITS distintas a nivel de especie que se obtuvieron a partir de puntas de raíces ectomicorrizadas de Fabaceae, estas secuencias no coinciden con ninguna especie morfológica representada en las bases de datos, tanto regionales como mundiales. Se presenta una clave taxonómica de las especies de Inocybe de Guyana, con ilustraciones de los nuevos taxones. Así como datos de los tipos de I. amazoniensis e I. matrisdei y material suplementario de I. epidendron e I. pulchela, estas últimas originalmente descritas de Guyana.

Behind the banner of culture? Gender, ‘race,’ and the family in Guyana
D. Alissa Trotz
New West Indian Guide , 2003,
Abstract: Suggests that the family plays a role in the production of gendered and racialized differences in the Caribbean. Author focuses especially on Guyana, and the differences between Afro- and Indo-Guyanese. First, she revisits earlier scholarly works on the Caribbean family, limited to domesticity and feminist responses. She stresses that representations of the Caribbean family serve(d) the imperatives of governance, and the social stratification, from colonial times to the present. She indicates how the Indo-Caribbean women as submissive housewives thus became opposed to the image of the Afro-Caribbean women as working matriarchs. She further discusses the historic development of the family and women's role therein among Indians in Guyana since indentureship, highlighting the strong influence of colonial manipulation.
