Présentation : With about 2500 species distributed all around the world, the tropical family Annonaceae is among the largest families of Angiosperms, and one of the largest ones with woody species. It is well represented in the three Guianas (Guyana, Suriname, French Guiana), with 140 species distributed in 1..
African names for American plants
No full textAfrican slaves brought plant knowledge to the New World, sometimes applying it to related plants they found there and sometimes bringing Old World plants with them. By tracing the linguistic parallels between names for plants in African languages and in communities descended from African slaves, pieces of the African slaves’ plant knowledge remain embedded in New World cultures. Ethnobotanist Tinde van Andel describes how such work has spawned new collaborations between botanists and linguists
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The history of the rice gene pool in Suriname: circulations of rice and people from the eighteenth century until late twentieth century
No full textAlongside the trans-Atlantic slave trade, plant species travelled from Africa to the Americas and back. This article examines the emerging rice gene pool in Suriname due to the global circulation of people, plants and goods. We distinguish three phases of circulation, marked by two major transitions. Rice was brought to the Americas by European colonizers, mostly as food on board of slave ships. In Suriname rice started off as a crop grown only by Maroon communities in the forests of the Suriname interior. For these runaway slaves cultivating several types of rice for diverse purposes played an important role in restoring some of their African culture. Rice was an anti-commodity that acted as a signal of protest against the slave-based plantation economy. After the end of slavery, contract labourers recruited from British India and the Dutch Indies also brought rice to Suriname. These groups grew rice as a commodity for internal and global markets. This formed the basis of a second transition, turning rice into an object of scientific research. The last phase of science-driven circulation of rice connected the late-colonial period with the global Green Revolution.</jats:p
The Diverse Uses Of Fish-Poison Plants In Northwest Guyana
No full textAlthough prohibited by law, fish
poison plants are still widely used by indigenous tribes in Guyana. The latest ethnobotanical
collections date from the first half of the 20th century and, from recent anthropological studies,
it cannot be deduced whether the same species are still used today. The present study attempts
to clarify the taxonomy and ethnobotany of the fish poisons, in particular those containing
rotenone, currently used by Amerindians in northwest Guyana. Specimens were collected from
11 species known to be ichthyotoxic, both from wild and cultivated sources. It was found that
fish poisons not only serve as a quick method of providing food in times of shortage, but also
play an important role in magic rituals and traditional medicine. Particularly striking was the
use of Lonchocarpus spp. and Tephrosia sinapou in the treatment of cancer and AIDS. Further
ethnobotanical and pharmacological research should focus on the medicinal applications of
rotenone-yielding plants
