Their fishery should be based on intimate knowledge of their ecology and biology.Feeding habits of the endemic Mochokid Synodontis koensis were assessed in the Sassandra River (Cote d’Ivoire) in relation to the study zone, the specimen sex and size, and the season.Of the 303 stomachs examined, 49 were empty (16%). The fluctuation of the vacuity index indicated that S. koensis feeds more at night. The diet consisted mainly of plant detritus and chironomid larvae. The statistical analysis of the feeding according to the study zones, the sex of fish and the seasons does not show any significant difference between regimes, whereas significant ontogenic shifts in diet were observed.1 aYao, S, S1 aKouame, K, A1 aOuattara, N, I1 aBi, Goore1 aKouamelan, E, P  uhttp://links.isiglobalnet2.com/gateway/Gateway.cgi?GWVersion=2&SrcAuth=mekentosj&SrcApp=Papers&DestLinkType=FullRecord&DestApp=WOS&KeyUT=00028088870000400600nas a2200121   4500008004100000245005100041210004700092260001500139520023100154100001600385700001600401856006100417       2010                        eng d00aThe status and distribution of freshwater fish0 astatus and distribution of freshwater fish  c2010/00/013 aFamily Total Number of endemics Number of threatened taxa CYPRINIDAE 34 22 11 CICHLIDAE 16 3 3 12 0 3 MORMYRIDAE 9 0 5 BAGRIDAE 8 0 2 ALESTIIDAE 8 0 1 CITHARINIDAE 6 0 2 CYPRINODONTIDAE 5 3 1 SCHILBEIDAE 4 0 1 SALMONIDAE 3 3 11 aYahyaoui, A1 aMelhaoui, M  uhttp://data.iucn.org/dbtw-wpd/edocs/2010-039.pdf#page=2602121nas a2200133   4500008004100000245007500041210006900116260001500185300001200200520146100212100002801673700002601701856026001727       2010                        eng d00aMorphology of the Gas Bladder in Sea Catfishes (Siluriformes: Ariidae)0 aMorphology of the Gas Bladder in Sea Catfishes Siluriformes Arii  c2010/00/01  a59 - 683 aThe morphology of the gas bladder and associated structures in sea catfishes (Siluriformes: Ariidae) is studied. The most simple gas bladder, exclusive to Galeichthys Valenciennes, is apple-shaped with weakly developed internal trabeculae, has smooth walls externally and a short Mullerian window associated with a broad, short Mullerian ramus that is firmly attached to Baudelot’s ligament and supracleithrum. Most genera of Ariidae have a cordiform bladder with well-developed trabeculae, smooth walls externally, an elongate Mullerian window and an elongate Mullerian ramus with an acute tip that is free from the Baudelot’s ligament and supracleithrum. Sciades proops (Valenciennes) and S. parkeri (Traill) have a similar gas bladder but with a well-developed secondary chamber. Other genera of Ariidae also have a cordiform bladder with well-developed trabeculae and elongate Mullerian window, but with lateral diverticula present as shallow rounded bulges or blister-like swellings along the peripheral margins of the bladder. The degree of development of lateral diverticula varies among and within species, with Osteogeneiosus Bleeker having the most highly-developed diverticula. Bagre pinnimaculatus (Steindachner) and Bagre bagre (Linnaeus) have unusual depressed gas bladders with complex network of internal trabeculae. The implications of gas bladder morphology for the taxonomy and phylogenetic relationships of the family are discussed.1 aMarceniuk, Alexandre, P1 aBirindelli, Jose, L O  uhttp://apps.isiknowledge.com/InboundService.do?Func=Frame&product=WOS&action=retrieve&SrcApp=Papers&UT=000281327500004&SID=3FMnoFdAmP2HF26KDo8&Init=Yes&SrcAuth=mekentosj&mode=FullRecord&customersID=mekentosj&DestFail=http%3A%2F%2Faccess.isiproducts.com%2F01541nas a2200133   4500008004100000245010200041210006900143260001500212300001400227490000700241520100400248100002301252856013201275       2010                        eng d00aA NEW SPECIES OF THE CATFISH NIGERIUM FROM THE PALAEOGENE OF THE TILEMSI VALLEY, REPUBLIC OF MALI0 aNEW SPECIES OF THE CATFISH NIGERIUM FROM THE PALAEOGENE OF THE T  c2010/00/01  a571 - 5940 v533 aThe phosphate deposits of the Tilemsi Valley, Republic of Mali, West Africa, are well known for their rich fossil vertebrate fauna including fishes, crocodilians, snakes and mammals. Despite this, the exact age of the deposits has been in some doubt. Here, a new species of catfish, Nigerium tamaguelense sp. nov., is described from the phosphate deposits at Tamaguelelt, Tilemsi Valley, based on a large collection of 29 well-preserved crania. The crania are compared with the known species of Nigerium, N. wurnoense White and N. gadense White. The genus Nigerium is reviewed and now placed in the family Claroteidae based on a combination of three derived characters. Nigerium is compared with other African fossil catfish genera and the fossil record of catfish families in Africa is reviewed. The new evidence presented here shows the Claroteidae to be the earliest occurring catfish family in Africa. Evidence is also presented for an Early Eocene age for the phosphate deposits at Tamaguelelt.1 aLongbottom, Alison  uhttp://onlinelibrary.wiley.com/doi/10.1111/j.1475-4983.2010.00946.x/abstract;jsessionid=2324B382003E44EA6DD501E5A3A54754.d02t0102130nas a2200229   4500008004100000245005900041210005800100260004200158300001100200490000600211520141300217100002201630700002201652700002301674700001701697700002201714700002001736700002201756700002301778700002001801856007901821       2010                        eng d00aPhenex: Ontological Annotation of Phenotypic Diversity0 aPhenex Ontological Annotation of Phenotypic Diversity  bPublic Library of Sciencec2010/00/01  ae105000 v53 aBackground: Phenotypic differences among species have long been systematically itemized and described by biologists in the process of investigating phylogenetic relationships and trait evolution. Traditionally, these descriptions have been expressed in natural language within the context of individual journal publications or monographs. As such, this rich store of phenotype data has been largely unavailable for statistical and computational comparisons across studies or integration with other biological knowledge.Methodology/Principal Findings: Here we describe Phenex, a platform-independent desktop application designed to facilitate efficient and consistent annotation of phenotypic similarities and differences using Entity-Quality syntax, drawing on terms from community ontologies for anatomical entities, phenotypic qualities, and taxonomic names. Phenex can be configured to load only those ontologies pertinent to a taxonomic group of interest. The graphical user interface was optimized for evolutionary biologists accustomed to working with lists of taxa, characters, character states, and character-by-taxon matrices.Conclusions/Significance: Annotation of phenotypic data using ontologies and globally unique taxonomic identifiers will allow biologists to integrate phenotypic data from different organisms and studies, leveraging decades of work in systematics and comparative morphology.1 aBalhoff, James, P1 aDahdul, Wasila, M1 aKothari, Cartik, R1 aLapp, Hilmar1 aLundberg, John, G1 aMabee, Paula, M1 aMidford, Peter, E1 aWesterfield, Monte1 aVision, Todd, J  uhttp://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.001050001626nas a2200193   4500008004100000245007800041210006900119260001500188300001400203490000700217520092700224100001601151700002001167700002801187700002001215700002101235700001901256856015701275       2010                        eng d00aThe early/late Pliocene ichthyofauna from Koro-Toro, Eastern Djurab, Chad0 aearlylate Pliocene ichthyofauna from KoroToro Eastern Djurab Cha  c2010/00/01  a241 - 2510 v433 aThis is the first extensive study of a freshwater fish fauna from the Pliocene site of Koro-Toro (Chad), aged 3.58 +/- 0.27 Ma. The assemblage includes an abafish (Mormyriformes, Gymnarchidae: Gymnarchus), a tigerfish (Characiformes, Alestidae: Hydrocynus), six different catfishes (Siluriformes, Ariidae: Carlarius; Bagridae: Bagrus; Claroteidae: Clarotes and Auchenoglanis; Mochokidae: Synadontis; Clariidae: Clarias or Heterobranchus), perciform fishes (Perciformes, Latidae: Lates sp. ef. niloticus, and Cichlidae indet.), and a pufferfish (Tetraodontidormes, Tetraodontidae: Tetraodon). The diversity is relatively low when compared with other Chadian Neogene sites. This is probably mostly explained by the wind erosion of the outcrops being responsible for the lack of minute remains. However, we recognize that the aquatic environment recorded corresponds to open waters.

The Phenoscape project aims to represent these complex and detailed descriptions with rich and formal semantics that are amenable to computation and integration with phenotype data from other fields of biology. This entails reconceptualizing the traditional free-text characters into the computable Entity-Quality (EQ) formalism using ontologies.Methodology/Principal Findings: We used ontologies and the EQ formalism to curate a collection of 47 phylogenetic studies on ostariophysan fishes (including catfishes, characins, minnows, knifefishes) and their relatives with the goal of integrating these complex phenotype descriptions with information from an existing model organism database (zebrafish, http://zfin.org). We developed a curation workflow for the collection of character, taxonomic and specimen data from these publications. A total of 4,617 phenotypic characters (10,512 states) for 3,449 taxa, primarily species, were curated into EQ formalism (for a total of 12,861 EQ statements) using anatomical and taxonomic terms from teleost-specific ontologies (Teleost Anatomy Ontology and Teleost Taxonomy Ontology) in combination with terms from a quality ontology (Phenotype and Trait Ontology). Standards and guidelines for consistently and accurately representing phenotypes were developed in response to the challenges that were evident from two annotation experiments and from feedback from curators.Conclusions/Significance: The challenges we encountered and many of the curation standards and methods for improving consistency that we developed are generally applicable to any effort to represent phenotypes using ontologies. This is because an ontological representation of the detailed variations in phenotype, whether between mutant or wildtype, among individual humans, or across the diversity of species, requires a process by which a precise combination of terms from domain ontologies are selected and organized according to logical relations. The efficiencies that we have developed in this process will be useful for any attempt to annotate complex phenotypic descriptions using ontologies. We also discuss some ramifications of EQ representation for the domain of systematics.1 aDahdul, Wasila, M1 aBalhoff, James, P1 aEngeman, Jeffrey1 aGrande, Terry1 aHilton, Eric, J1 aKothari, Cartik, R1 aLapp, Hilmar1 aLundberg, John, G1 aMidford, Peter, E1 aVision, Todd, J1 aWesterfield, Monte1 aMabee, Paula, M  uhttp://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.001070801608nas a2200193   4500008004100000245009900041210006900140260001500209300001600224490000800240520096500248100001801213700001301231700001301244700001501257700001401272700001801286856011001304       2010                        eng d00aFunctional study of the pectoral spine stridulation mechanism in different mochokid catfishes.0 aFunctional study of the pectoral spine stridulation mechanism in  c2010/00/01  a1107 - 11140 v2133 aMochokidae are able to produce pectoral spine stridulation sounds. During sound production, high speed videos were used to study the pectoral fin movements to identify the mechanisms involved. A call consisted of a series of pulses and occurred during a spine sweep, which was in fact made up of a series of jerky movements. The morphology of the pectoral spines and associated muscles was also observed in different species. The contractions of adductor profundus and superficial adductor allows adduction and abduction movements (sweep) of the spine, respectively. Simultaneously, the contraction of the arrector ventralis or the arrector 3 of the pectoral spine allows the pulling and pressing the ridges of the dorsal process, against the rough lateral face of the spinal fossa. This results in the rubbing of the ridges of the dorsal process, producing sounds. In Synodontis the analogy for sound production would be a brake shoe pressing against a wheel.1 aParmentier, E1 aFabri, G1 aKaatz, I1 aDecloux, N1 aPlanes, S1 aVandewalle, P  uhttp://eutils.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&id=20228347&retmode=ref&cmd=prlinks00771nas a2200145   4500008004100000245009600041210007000137260005700207520024800264100002000512700001500532700001800547700001600565856004400581       2010                        eng d00aContribution à la connaissance de l’ichtyofaune de l’Inkisi au Bas-Congo (RD du Congo)0 aContribution à la connaissance de l ichtyofaune de l Inkisi au B  bSociété fran{\c c}aise d’ichtyologiec2010/00/013 aAmphiliidae Amphilius zairensis Skelton, 1986 x Doumea alula nichols & griscom, 1917 xxxx x Phractura brevicaudata boulenger, 1911 x Mochokidae batesii boulenger, 1904 x congicus boulenger, 1920 x Euchilichthys guentheri (Schilthuis, 1891) xxx1 aLunkayilakio, W1 aVreven, EJ1 aVandewalle, P1 aMutambue, S  uhttp://orbi.ulg.ac.be/handle/2268/6776202391nas a2200145   4500008004100000245014500041210006900186260001500255300001400270490000700284520176100291100002002052700001602072856015702088       2010                        eng d00aThe bony anatomy of Chadian Synodontis (Osteichthyes, Teleostei, Siluriformes, Mochokidae): interspecific variations and specific characters0 abony anatomy of Chadian Synodontis Osteichthyes Teleostei Siluri  c2010/00/01  a173 - 2310 v323 aThe genus Synodontis Cuvier, 1816 (Siluriformes, Mochokidae) numbers about 120 species and is exclusive to the freshwater of Africa except Maghreb and Cape Province It is one of the most widespread catfish of African freshwater The Synodontis fossil record covers the last 18 Myr and most of the Synodontis fossil hones are found in a disarticulated state The identification of the fossils at a specific level is so far impossible, because we lack an osteological study of the species.
