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. -

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. -

Diet-Morphology Relationships of Some Fish Species in the Cross River Estuary, Southeast Nigeria
International Journal of Fisheries and Aquaculture Research Vol.3, No.2, pp.10-29, July 2017 Published by European Centre for Research Training and Development UK (www.eajournals.org) DIET-MORPHOLOGY RELATIONSHIPS OF SOME FISH SPECIES IN THE CROSS RIVER ESTUARY, SOUTHEAST NIGERIA James P. Udoh1* and Imaobong E. Ekpo2 Department of Fisheries and Aquatic Environmental Management, Faculty of Agriculture, University of Uyo, Uyo, Nigeria. ABSTRACT: Fish exploit the diversities of food organisms and habitats in their aquatic environments according to their structural morphology and feeding habits, hence its ecological roles and functions. Six morphological measurements and dietaries of 582 stomachs of eleven (11) species in the Cross River estuary, Nigeria, were examined from August-December, 2014 to establish interrelationship of diet and morphology. TrophLab® estimated the trophic level (TL) for each species. Dietaries reveal 3 to 11 food items on which basis species were grouped into three functional trophic guilds: omnivore (6 species), detritivore-algivore (2 species) and carnivore (3 species). Positive linear relationship was established between total length (TL) 2 and mouth area (MA) (r = 0.31 - 0.96; p < 0.5; r > 0.5 in Cynoglossus senegalensis and Liza falcipinnis, r2 < 0.5 for other species) except in the cichlid Ethmalosa fimbriata (r = 0.000267; p = 0.9997). Higher relationships were established in mouth area (MA) and mouth dimensions (MV and MH) with trophic levels (TLs) among species within same trophic guild than when non- related species were combined: detritivore (r2 = 1.00), carnivore (r2 = 0.91), omnivore (r2 = 0.4348), and all species combined (r2 = 0.1414). -

Dept of Animal Science & Fisheries. Faculty of Agriculture,Univ of Port Harcourt (Uniportt) 2.Dept of Animal and Environmental Biology. Uniport 3.Dept of Fisheries & Marine, Fac of Agric., Imo State Polytechnic, Umuagwo *Corresponding author: [email protected] Abstract Fish species of Oguta Lake were sampled for seven months to acertain present status. The catch consisted of 5 orders, 15 families, 21 genera and 28 species. Bagridae, Characidae, Anabantidae, Citharinidae and Notopteridae were dominant families in terms of numbers; in terms of species, Cichlidae was most dominant ( 5 species). In descending order number of species identified were: three each, for Mormyridae, Characidae and Mochokidae; and a species or two for each of the remaining 11 families, indicating that there could be high risk of complete wipe out of such families under sudden adverse environmental conditions. As a potential source of socio-economic development to surrounding communities the anthropogenic activities on this lake should be defined in order to forestall the gradual and continuous loss of its useful services. The root crop cassava (Manihot sp.) cottage industry can be sited by the lake to stop its direct processing within the lake. Domestic waste should not be dumped directly into the lake as well. -

Ichthyofauna Diversity of Lake Asejire: Ecological Implications
Vol. 5(10), pp. 248-252, Oct, 2013 International Journal of Fisheries and DOI: 10.5897/IJFA13.0379 ISSN 1991-637X©2013 Academic Journals Aquaculture http://www.academicjournals.org/IJFA Full length Research paper Ichthyofauna diversity of Lake Asejire: Ecological implications Ipinmoroti, Mabel Omowumi Department of Renewable Resources, College of Agricultural Science, Olabisi Onabanjo University, Ago–Iwoye, Ogun State, Nigeria. Accepted 19 August, 2013 The natural diversity of most aquatic systems has witnessed various changes in stock diversity and abundance resulting from structural changes in habitat, food composition and uncontrolled exploitation. These have altered the ecology of the fish resources with the disappearance of some species and dominance of others. This study seeks to identify the ecological implication of the stock diversity and abundance in Lake Asejire. Lake Asejire is a 525 ha man-made lake on river Osun one of the major rivers that drain the western part of Nigeria. Fish samples were collected for a period of 24 months using gillnets of between 25 and 187.5 mm mesh sizes. Data obtained were analyzed using inferential statistics and descriptive analysis of means, frequencies and percentages. Seventeen families identified and grouped into trophic levels. Herbivores were 63.03 and 60.35%; carnivore 31.05 and 30.65% and omnivores were 5.91 and 8.99% by biomass in the first and second year respectively. The herbivores were dominated by the cichlids, heterotis and cyprinids; carnivores by bagrids, characids, channids and Lates while mormyrids, synodonts and clarids constitute the omnivores. Seasons had no effect on the population and number of the carnivores. -

Tempo and Mode of Lineage and Morphological Diversification in a Hyperdiverse Freshwater Fish Radiation (Teleostei: Characiformes)
AN ABSTRACT OF THE DISSERTATION OF Michael D. Burns for the degree of Doctor of Philosophy in Fisheries Science presented on April 17, 2018. Title: Tempo and Mode of Lineage and Morphological Diversification in a Hyperdiverse Freshwater Fish Radiation (Teleostei: Characiformes) Abstract approved: ________________________________________________ Brian L. Sidlauskas Characiform fishes form one of the most diverse freshwater fish clades in the world. Comprising more than 2000 species and distributed primarily in South America and Africa, characiforms vary dramatically in their ecomorphology. However, the evolutionary processes responsible for the immense ecomorphological diversity remains unknown. Recently, a study postulated that the unparalleled ecomorphological diversification arose through an ancient adaptive radiation, as evidenced by the clear segregation of morphological traits, such as body shape, among different trophic and habitat groups. However, no formal macroevolutionary analyses have been conducted on the entire order of Characiformes and the mechanism responsible for the diversity remains unknown. Here, I conduct a macroevolutionary analysis of body shape diversification to determine if Characiformes evolved through an adaptive radiation. I estimated the first time-calibrated molecular phylogeny for the order Characiformes, assembled the first ever geometric morphometric body shape dataset, and compiled an exhaustive trophic ecology database. In my second chapter, I combined these datasets to test whether body shape adapted -
