ACCRONYMES IUCN International Union for the Conservation of Nature OMVG The Gambia River Basin Development Organization OMVS Organization for the Development of the Senegal River INTRODUCTION The Gambia River Basin Development Organization (OMVG), which includes The Gambia, Guinea, Senegal and Guinea-Bissau, looks to further improve the socio-economic integration of the four member states through the development and management of resources in the Gambia basin, Kayanga (Senegal), Geba (Guinea Bissau), Koliba (Guinea), and Corubal (Guinea Bissau). The project’s objective is to increase the agro forestry and pastoral yield, streamline the procurement of natural resources and improve infrastructure and Social Services. It also seeks to reduce poverty on a sustainable basis and improve the conditions of the populations established in the Gambia River basin. OMVG has committed to an important infrastructure project to reduce the energy deficit of its member countries. The project includes hydroelectric dams in Senegal (Sambangalou) and in Guinea (Kaleta) with regional integration of power grids in the four countries. The bigger of the two projects is the Sambangalou dam, which will have a 400 Gigawatt (GWh) capacity. In addition to the dams and power stations in Senegal and Guinea, the construction of 225 kilovolt (kV) power lines connecting the plant and the four countries is included in the project. In order to mitigate the impact of constructing the Sambangalou dam, OMVG has partnered with Wetlands International and the International Union for the Conservation of Nature (IUCN) with the objective of conserving biodiversity in the Gambia River basin within the framework of the demonstration project. The biodiversity gap assessment has provided basic information for species’ development and monitoring. Biodiversity conservation will also enable the development of eco-tourism. This local development will move forward via the training of targeted community groups to raise awareness of the importance of biodiversity conservation. Thus, this module on freshwater fish is destined for trainers and for the monitoring of biodiversity, especially once the Sambangalou dam is functional, in relation to the creation of an observatory. The information issuing from this biodiversity monitoring will serve as a support to future habitat construction projects and approved plans for species conservation. Wetlands International, in collaboration with IUCN, has implemented a program entitled "Integration of Freshwater Biodiversity in Africa’s Development Process: Mobilization of Information and Demonstration Sites. The Gambia River Basin Development Organization (OMVG) which is composed of The Gambia, the Republic of Guinea, Guinea Bissau and Senegal, plans to build a dam on the Sambangalou site. The construction of this dam will involve a significant disturbance to biodiversity as proven by the impact studies conducted by OMVG. In order to mitigate the negative impact of this project, and to simultaneously improve those that are positive, Wetlands International Africa, in partnership with the IUCN- Species Survival Commission and the OMVG Organization, through Phase 2 entitled "Demonstration Project of the Gambia River (West Africa)" within the program "Integration of Freshwater Biodiversity in Africa’s Development Process: Mobilization of Information and Demonstration Site" agree on the implementation of a plan to monitor the biodiversity of freshwater ecosystems in the Gambia River basin. In order to get important information on all ecosystems and especially on key species and habitats, it is important that all stakeholders are given the tools to undertake the monitoring of biodiversity in general and of key species related to this specific project. As for the various challenges and issues at this point in time, it is appropriate to provide training on the adapted monitoring methods. Thus, Wetlands International Africa decided to develop a training module for trainers on freshwater fish. GOALS AND OBJECTIVES OF THE MODULE This module is designed for the state’s technical services, NGOs and local communities of the Gambia River Basin to implement in a practical manner a preliminary monitoring plan of freshwater biodiversity of the Gambia River basin. It offers a precise and operational methodology to monitor the status and dynamics of freshwater crabs. The development of this type of course involves choices that must eventually be adjusted in the field. Ultimately, this course will enable the : • Strengthening of the capacities of trainers in the monitoring of species for the conservation of species biodiversity • Evaluation of the educational means and training plan for targeted groups • Provision of information on the impacts of the construction of the Sambanganlou hydroelectric dam Arius parkii (FAO, fishbase) MODULE CONTENT This module is for the training of trainers who will be able to disseminate widely within the communities or other targeted groups the need for the conservation of the biological diversity of the Gambia River basin and to adapt to changes resulting from the establishment of the Sambangalou dam. The training aims to teach participants the concepts of biological diversity conservation, the identification of monitored species, collection of biological, environmental and socio-economic data and the archiving of data for in-depth analysis and processing by the observatory. The training module on fish requires 28 hours of course work distributed as follows: • General information on the Gambia River Basin ecosystems

    Phylogenetic Relationships Within the Speciose Family Characidae

    Oliveira et al. BMC Evolutionary Biology 2011, 11:275 http://www.biomedcentral.com/1471-2148/11/275 RESEARCH ARTICLE Open Access Phylogenetic relationships within the speciose family Characidae (Teleostei: Ostariophysi: Characiformes) based on multilocus analysis and extensive ingroup sampling Claudio Oliveira1*, Gleisy S Avelino1, Kelly T Abe1, Tatiane C Mariguela1, Ricardo C Benine1, Guillermo Ortí2, Richard P Vari3 and Ricardo M Corrêa e Castro4 Abstract Background: With nearly 1,100 species, the fish family Characidae represents more than half of the species of Characiformes, and is a key component of Neotropical freshwater ecosystems. The composition, phylogeny, and classification of Characidae is currently uncertain, despite significant efforts based on analysis of morphological and molecular data. No consensus about the monophyly of this group or its position within the order Characiformes has been reached, challenged by the fact that many key studies to date have non-overlapping taxonomic representation and focus only on subsets of this diversity. Results: In the present study we propose a new definition of the family Characidae and a hypothesis of relationships for the Characiformes based on phylogenetic analysis of DNA sequences of two mitochondrial and three nuclear genes (4,680 base pairs). The sequences were obtained from 211 samples representing 166 genera distributed among all 18 recognized families in the order Characiformes, all 14 recognized subfamilies in the Characidae, plus 56 of the genera so far considered incertae sedis in the Characidae. The phylogeny obtained is robust, with most lineages significantly supported by posterior probabilities in Bayesian analysis, and high bootstrap values from maximum likelihood and parsimony analyses.

    Mitochondrial DNA, 2011; Early Online: 1–9 DNA barcoding discriminates freshwater fishes from southeastern Nigeria and provides river system-level phylogeographic resolution within some species CHRISTOPHER D. NWANIa, SVEN BECKERb, HEATHER E. BRAIDb, EMMANUEL F. UDEc, OKECHUKWU I. OKOGWUa, & ROBERT HANNERb aDepartment of Applied Biology, Ebonyi State University, Abakaliki, Nigeria, bDepartment of Integrative Biology, Biodiversity Institute of Ontario, University of Guelph, Guelph, Ontario, Canada, and cFisheries and Aquaculture, Ebonyi State University, Abakaliki, Nigeria (Received 17 August 2010; revised 28 October 2010; accepted 28 October 2010) Abstract Background and aims: Fishes are the main animal protein source for human beings and play a vital role in aquatic ecosystems and food webs. Fish identification can be challenging, especially in the tropics (due to high diversity), and this is particularly true for larval forms or fragmentary remains. DNA barcoding, which uses the 50 region of the mitochondrial cytochrome c oxidase subunit I (cox1) as a target gene, is an efficient method for standardized species-level identification for biodiversity assessment and conservation, pending the establishment of reference sequence libraries. Materials and methods: In this study, fishes were collected from three rivers in southeastern Nigeria, identified morphologically, and imaged digitally. DNA was extracted, PCR-amplified, and the standard barcode region was bidirectionally sequenced for 363 individuals belonging to 70 species in 38 genera. All specimen provenance data and associated sequence information were For personal use only. recorded in the barcode of life data systems (BOLD; www.barcodinglife.org). Analytical tools on BOLD were used to assess the performance of barcoding to identify species. Results: Using neighbor-joining distance comparison, the average genetic distance was 60-fold higher between species than within species, as pairwise genetic distance estimates averaged 10.29% among congeners and only 0.17% among conspecifics.

Hilton1 and Sébastien Lavoué2,3 The bony-tongue fishes, Osteoglossomorpha, have been the focus of a great deal of morphological, systematic, and evolutio- nary study, due in part to their basal position among extant teleostean fishes. This group includes the mooneyes (Hiodontidae), knifefishes (Notopteridae), the abu (Gymnarchidae), elephantfishes (Mormyridae), arawanas and pirarucu (Osteoglossidae), and the African butterfly fish (Pantodontidae). This morphologically heterogeneous group also has a long and diverse fossil record, including taxa from all continents and both freshwater and marine deposits. The phylogenetic relationships among most extant osteoglossomorph families are widely agreed upon. However, there is still much to discover about the systematic biology of these fishes, particularly with regard to the phylogenetic affinities of several fossil taxa, within Mormyridae, and the position of Pantodon. In this paper we review the state of knowledge for osteoglossomorph fishes. We first provide an overview of the diversity of Osteoglossomorpha, and then discuss studies of the phylogeny of Osteoglossomorpha from both morphological and molecular perspectives, as well as biogeographic analyses of the group. Finally, we offer our perspectives on future needs for research on the systematic biology of Osteoglossomorpha. Keywords: Biogeography, Osteoglossidae, Paleontology, Phylogeny, Taxonomy. Os peixes da Superordem Osteoglossomorpha têm sido foco de inúmeros estudos sobre a morfologia, sistemática e evo- lução, particularmente devido à sua posição basal dentre os peixes teleósteos.

Twenty-six characters derived from comparisons of osseous structures among some aplocheiloid fi shes provided evidence supporting hypotheses of relationships among three western African genera (Callopanchax, Scriptaphyosemion and Archiaphyosemion), as proposed in recent molecular analysis. The clade comprising Callopanchax, Scriptaphyosemion and Archiaphyosemion is supported by a laterally displaced antero-proximal process of the fourth ceratobranchial. The sister group relationship between Callopanchax and Scriptaphyosemion is supported by a constriction on the posterior portion of the parasphenoid, an anterior expansion of the hyomandibula, a rectangular basihyal cartilage, an anterior pointed process on the fi rst vertebra, and a long ventrally directed hemal prezygapophysis on the preural centrum 2. Monophyly of Callopanchax is supported by a convexity on the dorsal margin of the opercle, a long interarcual cartilage, and long neural prezygapophyses on the anterior caudal vertebrae. > Key words Killifi shes, Callopanchax, Africa, Osteology, Annual fi shes.
