Etudes écologique, floristique, phytosociologique et ethnobotanique de la forêt marécageuse de Lokoli, Zogbodomey - Bénin / Ecological, floristic, phytosociological and ethnobotanical studies of the swamp forest of Lokoli, Zogbodomey - Benin

Dan, Céline 29 June 2009 (has links)
Etudes écologique, floristique, phytosociologique et ethnobotanique de la forêt marécageuse de Lokoli (Zogbodomey – Bénin)<p><p>La forêt marécageuse de Lokoli, située dans le sud du Bénin est une formation non protégée, bien qu’elle soit la seule forêt marécageuse avec un cours d’eau permanent connue en Afrique de l’Ouest. Pour envisager une prise de décision de conservation et de protection de cet écosystème forestier, il est important de disposer d’une meilleure connaissance de sa flore, de sa végétation et de son fonctionnement. C’est dans ce cadre que la présente étude a été envisagée. Les données collectées concernent le milieu naturel, la structure de la forêt, la régénération naturelle des espèces et les usages faits des Produits Forestiers Non Ligneux (PFNL).<p>Le milieu naturel se compose d’un substratum acide (pH variant de 3,5 à 5,5) et argilo-sableux. Le cortège floristique de cette forêt est composé de 241 espèces réparties en 185 genres et 70 familles dont des espèces endémiques (Uapaca paludosa) ou en danger (Hallea ledermannii), Nauclea xanthoxylon, etc. <p>Sept groupements végétaux ont été identifiés (forêt primaire inondée à Alstonia congensis et Xylopia rubescens, forêt secondaire inondée à Ficus trichopoda et Spondianthus preussii et raphiale à Raphia hookeri et Anthocleista vogelii en forêt ;forêt ripicole à Alchornea cordifolia et Mitragyna inermis, savane marécageuse à Ficus asperifolia et Paullinia pinnata ;prairie marécageuse à Cyclosorus gongylodes et Polygonum pulchrum et enfin prairie marécageuse à Rhynchospora corymbosa et Ludwigia abyssinica en lisière) avec des précisions sur leurs caractéristiques floristiques, biologiques, phytogéographiques et écosociologiques. Les mésophanérophytes sont abondants en forêt alors qu’en lisière, ce sont les microphanérophytes qui sont les plus nombreux. Ces groupements constituent un refuge pour de nombreuses espèces animales dont Barboides britzi, poisson déterminé pour la première fois en 2006. D’après cette étude, on note une bonne régénération des espèces forestières malgré une recrudescence des trouées liées à l’installation de champs de Colocasia esculenta. <p>Parmi les 75 espèces, source de PFNL recensées, les produits et sous-produits issus de Raphia hookeri sont les plus exploités car ils constituent pour les populations riveraines d’importantes sources de revenus. Ces PFNL sont exploités à Lokoli pour plusieurs usages à savoir l’alimentation, l’emballage, boisson alcoolisée, recettes médicinales, construction, etc. Le nombre de pieds de Raphia hookeri saignés par an est de 15.452 par 320 exploitants dont 148 cueilleurs, 81 transformateurs et 91 commerçants ;ce qui fournit aux exploitants des revenus de l’ordre de 28.000 à 159.000 FCFA (42,7 à 242,4 euros) par mois et par exploitant, sans oublier les autres activités menées par les riverains dans cet écosystème. On note une forte pression anthropique sur cette formation qu’il est donc urgent de protéger. <p>En effet, elle dispose d’importants atouts qui militent en faveur de sa conservation. Elle abrite des espèces végétales et animales rares, endémiques, vulnérables et en danger (inscrites sur la liste rouge de l’UICN), telles que :Hallea ledermannii, Uapaca paludosa, Nauclea xanthoxylon, Cercopithecus erythrogaster erythrogaster, Cercopithecus mona, Colobus vellerosus, Ceriagrion citrinum Campion, Barboides britzi, etc. La forêt marécageuse de Lokoli joue un rôle de refuge pour toutes ces espèces qui y trouvent leur niche écologique. Sur le plan socio-économique, la FML fournit aux populations riveraines des revenus pour leur subsistance. Toutes ces potentialités font d’elle une Forêt à Haute Valeur pour la Conservation (FHVC) et elle pourrait constituer une véritable réserve de biosphère dans le Sud-Bénin.<p> <p>Ecological, floristic, phytosociological and ethnobotanical studies of the swamp forest of Lokoli (Zogbodomey - Benin)<p><p>The swamp forest of Lokoli, located in the south of Benin, is a non-protected area, although it is the only swamp forest in West Africa accompanied by a river which always contains water. To be able to make decisions concerning the conservation and protection of this forest ecosystem, it is important to have a better knowledge of its flora, its vegetation and its ecology and dynamics. It is within this framework that the present study was considered. The data that were collected relate to the natural environment, the structure of the forest, the natural regeneration of the species and the uses of the Non Timber Forest Products (NTFP).<p>The natural environment is composed of a substratum which is acid (pH varying from 3.5 to 5.5) and loamy-sandy. The floristic composition of this forest is composed of 241 plant species from 185 genera and 70 families.<p>Seven vegetation types were identified: 1. Inundated primary forest with Alstonia congensis and Xylopia rubescens; 2. Inundated secondary forest with Ficus trichopoda and Spondianthus preussii; 3. Raphia forest with Raphia hookeri and Anthocleista vogelii; 4. Riparian forest with Alchornea cordifolia and Mitragyna inermis; 5. Marshy savanna with Ficus asperifolia and Paullinia pinnata; 6. Marshy savanna with Cyclosorus gongylodes and Polygonum pulchrum; and 7. Marshy savanna with Rhynchospora corymbosa and Ludwigia abyssinica. Precise details are given on their floristic, biological, phytogeographical and phytosociological characteristics. The mesophanerophytes are abundant in forest whereas at forest edges the microphanerophytes are most numerous. These vegetation types constitute a refuge for many animal species, for example Barboides britzi, a species of fish first identified in 2006. This study noted a good regeneration of forest species, in spite of disturbance related to the installation of fields of Colocasia esculenta.<p>About 75 investigated NTFP are exploited in Lokoli for many purposes, among which food, packaging, alcoholic drinks, medicines, construction, etc. Among the listed NTFP, the products and by-products made from Raphia hookeri are the most important because they are important sources of revenue for the inhabitants of the area. The number of stems of Raphia used per year for palm wine production is 15.452 by the 320 inhabitants, including 148 gatherers, 81 transformers and 91 tradesmen. This provides to the inhabitants an income of about 28,000 to 159,000 FCFA per month and per inhabitant, without forgetting the other activities undertaken by these inhabitants. This results in a strong human pressure on the vegetation of the area which is therefore in urgent need of protection.<p>The vegetation of the Lokoli forest has important values which indicate its conservation concern. It shelters plant and animal species that are endemic and/or endangered or vulnerable according to the red list of the IUCN, such as: Hallea ledermannii, Uapaca paludosa, Nauclea xanthoxylon, Cercopithecus erythrogaster erythrogaster, Cercopithecus mona, Colobus vellerosus, Ceriagrion citrinum Campion, Barboides britzi, etc. The swamp forest of Lokoli is a refuge for all these species who find here their ecological niche. On the socio-economic level, the Lokoli forest provides to the inhabitants an income for their subsistence. The Lokoli forest in southern Benin is a forest with a high conservation value and it has the potential to become a “biosphere reserve”.\ / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

Genetic dissection reveals distinct roles for the transcription factor ZHOUPI in controlling Arabidopsis endosperm cell death and embryonic cuticle development

Xing, Qian January 2012 (has links)
Angiosperm seed development requires co-ordinated development of the embryo and a second zygotic tissue, the endosperm. In Arabidopsis thaliana, the endosperm is ephemeral and is largely consumed by the embryo during seed development. In addition to a role in embryo nutrition, it is also likely that the endosperm may play a more direct role in signalling to the embryo to regulate development. Despite their importance for embryo development, these processes are very poorly understood. The ZHOUPI (ZOU) gene provides an important tool to address these problems. Firstly, ZOU likely regulates endosperm breakdown. Whereas wild-type seed have a single layer of endosperm at maturity, zou seed has a large persistent endosperm and a correspondingly small embryo. The small zou embryo does not fill the seed so that the seed shrivels as it desiccates during maturation. Secondly, zou embryos have defects in their cuticle, so that the endosperm adheres to the embryo throughout seed development. After seed germination, zou cotyledons develop holes in their epidermis as they expand, probably due to the defects in the cuticle. ZHOUPI (ZOU) encodes a bHLH transcription factor and is expressed in the embryo surrounding region (ESR) of endosperm but not in the embryo itself. The role of ZOU in cuticle development is partly mediated by the ABNORMAL LEAF SHAPE1 (ALE1) gene. Thus, ale1 mutants also show defects in embryonic cuticle development and ALE1 is specifically expressed in ESR in a ZOU-dependent fashion. It was unclear whether the effects of ZOU upon embryo development are an indirect consequence of the persistent endosperm mechanically impeding embryo expansion, or rather reflect a more direct role of the ESR in signalling to the embryo. The main aims of this thesis were 1) to provide evidence that ZOU regulates endosperm cell death and 2) to test whether ZOU function in controlling endosperm cell death could be separated from that in embryonic epidermal cuticle development. To achieve this goal, 1) TUNEL assays were performed in the seeds to confirm the zou endosperm cell death phenotype, 2) ALE1 expression in the ESR in zou mutants was rescued using the ZOU-independent AtSUC5 promoter to investigate whether one or both of zou phenotypes were complemented, 3) Candidate ZOU target genes were validated and characterized to determine their functions in endosperm cell death and/or embryonic epidermal cuticle development. The TUNEL assays revealed that zou mutants display less DNA fragmentation in the ESR than that of the wild-type, but that zou did not have defects in cell death outside the seeds suggesting ZOU specifically regulated endosperm cell death. The AtSUC5::ALE1 transgene partially rescued zou defects in epidermal cuticle but not in endosperm cell death. This shows that the defects in the zou cuticle are not caused by the defective endosperm, rather zou has distinct, separable functions. Lastly, I characterised several novel ZOU targets and showed that RGP3 may be a direct ZOU target as it is expressed in ESR in ZOU dependent fashion, whereas RGP4 is likely indirect as it is expressed in the testa and up-regulated in zou mutants. In conclusion, ZOU has independent roles in endosperm cell death and embryonic epidermal cuticle development. Because ALE1, which largely mediates the role in cuticle development, is less widely conserved than is ZOU, the role in promoting endosperm cell death may be the ancestral function of ZOU.

A Study of Zou yan shu, Unearthed from Zhangjiashan Han Dynasty Tomb 247

Zhou, Min-hwa 07 February 2012 (has links)
From December 1983 to January 1984, 228 bamboo strips were unearthed in M247 at Jiangling, Hubei. These strips contained a collection of criminal cases called Zou Yan Shu, as well as 526 strips containing Laws of the 2nd Year. This discovery effectively patched a gap in judicature during the transition from the Qin to the Han. Beginning in 1985, a research group, Li Xueqin, and Peng Hao, began publishing the content of these strips in Wenwu. Soon scholars all over the world began researching the strips. In 2008, the Bamboo and Silk Manuscript Center at Wuhan University used infrared imaging (as well as referencing Cai Wanjin¡¦s revisions of the text and the research of other scholars) to make sense of a very muddled text. This also brought about many breakthroughs in research on the Zou Yan Shu. Now scholars understand much more concerning judicature during the Qin-Han period and how it differed from that of pre-Qin times. Despite this, few scholars have attempted a comprehensive analysis of the 22 cases found in this work. There is much research to be done on legal terminology in the text, the judiciary writing process in Zou Yan Shu, the reasons for compiling these 22 cases, knowledge of judiciary principles during Qin-Han gained from these cases, and several keys to unjust, falsified, and mistaken cases. This dissertation attempts to utilized prior understanding of the scholarly community to systematically and comprehensively analyzing all 22 cases and to explicate the meaning of the title Zou Yan Shu, judiciary terminology, the judiciary process, adjudicatory results, and reasons for the unjust, falsified, and mistaken cases. It was discovered that the purpose for this compilation was to educate law-enforcement officials and portrays the message that from receiving the initial report to apprehending and trying the criminal to gathering evidence to issuing the final judgment, if the principle ¡§all is decided by the law¡¨ is not strictly adhered to then mistakes are easily made. In addition, the way documents are written in Zhou Yan Shu is closely related to the judiciary process from the county-level all the way to the Commandant of Justice, revealing how this process worked at the various levels.

Identiteitsbeelding in poësie vir die adolessent : 'n vergelykende studie tussen 'n Afrikaanse en 'n Nederlandstalige bloemlesing / H.C. van der Walt

Van der Walt, Hester Carina January 2004 (has links)
Anthologies composed for adolescent readers are rare in both Afrikaans and Dutch. These anthologies are published at quite lengthy intervals, because they are post-publications in which already published volumes are absorbed. These anthologies are, however, to an increasing extent the medium by which readers become aware of poetry and are also introduced to different poets. For that reason it can be concluded that anthologies inform poetic taste. The empathy and love towards poetry experienced by young children in both languages are gradually replaced by an apathetic attitude towards poems and even an antipathetic attitude in general during adolescence. The first reaction to poetry is usually emotional and this indicates the way for further intellectual development. When selecting poems for the adolescent reader, the different developmental aspects affecting the adolescent and his identity development must be taken into consideration. The needs of the adolescent reader must be kept in mind. Needs in reading develop as a result of general needs that should be satisfied in the first place. Should this be the case, the need for reading would develop. In this study different theoretical points of view, namely reader-response criticism, developmental psychology, general needs and reading-related needs are used to determine the representation of identity in poems. Specific theories of poetry are used as instruments in text studies and analyses with regard to representation of identity in anthologies for adolescents. Poems in Versreise (Vermaak et al.) and Met gekleurde billen zou her gelukkiger leven zijn (Van Coillie) are analysed focusing on the representation of time and space, speaker and perspective, atmosphere and metaphorical language. For the purposes of this study analyses were conducted to evaluate and interpret the representation of identity in the texts of both anthologies. The differences and similarities between the Afrikaans and Dutch poetry texts for the adolescent had to be identified. The differences were used to determine which type of text would support the Afrikaans identity, the Dutch identity or the Flemish identity. The similarities, on the other hand, were used to determine the type of text that would not appeal to the Afrikaans, Dutch or Flemish adolescents only, but to adolescents in general. In this study method-pluralism is scientifically unavoidable. Different methods were systematically combined to support the specific methods of approach. The research was done in accordance with four methods: a synopsis of existing and appropriate theory of literature and forming of theory with regard to relevant concepts and terms; the analyses of texts in two anthologies; a summary of critical opinions stated in different reviews as well as surveys and interviews based on consultations via e-mail with the different role players, i.e. the anthology composers, illustrators and publishers. / Thesis (MA (Afrikaans en Nederlands))--North-West University, Potchefstroom Campus, 2004.
