  • 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.

MONGDONG Conservation International Indonesia Marine Program, Jl. Dr. Muwardi No. 17, Renon, Denpasar 80235 Indonesia E-mail: [email protected] Abstract A new species of gobiid fish, Vanderhorstia dawnarnallae, is described from West Papua Province, Indonesia, on the basis of two male specimens, 39.1 and 39.2 mm SL. Diagnostic features include 13 dorsal-fin and anal- fin segmented rays, third dorsal-fin spine long and filamentous, 47–49 lateral scales, body scales mostly cycloid, posteriormost scales of caudal peduncle finely ctenoid, and scales absent on head and nape region. Color in life is pale greyish to yellowish white with 5 mid-lateral clusters of blue-margined yellow spots with one or two vertical rows of 3–5 blue-margined yellow spots between clusters. The new species is most similar to Vanderhorstia phaeosticta from the western Pacific Ocean, but differs most notably in lacking pronounced sexual dichromatism.

This paper documents the diet of 71 fish species (among the 140 recorded) and compares the taxonomic and trophic structure of fish assemblages between four lake types. The diet analysis was conducted to determine five trophic guilds: algivores/iliophages, herbivores, zooplanktivores, invertivores and piscivores. The taxonomic and trophic structures of the fish assemblages were not similar in the different lake types of the Mamore´ River. The trophic structure of assemblages showed a coarse pattern of dominance of algivores/iliophages Key words: Bolivia; river floodplain; tropical and invertivores, but different situations were observed in relative freshwater fishes; distribution pattern; diet abundance of the trophic groups in relation to the spatial position of the lakes (except for piscivores).

  • Social Behaviour and Mating System of the Gobiid Fish Amblyeleotris Japonica
    Japanese Journal of Ichthyology 魚 類 学 雑 誌 Vol.28,No.41982 28巻4号1982年 Social Behaviour and Mating System of the Gobiid Fish Amblyeleotris japonica Yasunobu Yanagisawa (Received March 26,1981) Abstract The behaviour,social interactions and mating system of the gobiid fish Amblyeleotris japonica,that utilize the burrows dug by the snapping shrimp Alpheus bellulus as a sheltering and nesting site,were investigated at two localities on the southern coast of Japan.The fish spent most of their time in the area near the entrance of the burrow in daytime.Movements were limited to an area of about three metres in radius from the entrance.Aggressive encounters occurred between adjacent individuals sometimes resulting in changes of occupation of burrows. Males were more active in pair formation,whereas females were rather passive.Paris were usually maintained for several days or more,but some of them broke up without spawning.All the males that successfully spawned were larger ones that were socially dominant,and they re- mained within the burrow for four to seven days after spawning to care for a clutch of eggs. Variation in social interactions and burrow-use was recognized between two study populations and was attributed to the differences in predation pressure and density of burrows. A number of species of Gobiidae are known history and pair formation of the shrimp to live in the burrows of alpheid shrimps in Alpheus bellulus are described.In this study, tropical and subtropical waters(Luther,1958; the behaviour,social interactions and mating Klausewitz,1960,1969,1974a,b;Palmer,1963; system of its partner fish Amblyeleotris japonica Karplus et al.,1972a,b;Magnus,1967;Harada, are investigated and analyzed.

The sampling was conducted from 2012 to 2013 during the dry season. Fish were collected with dip nets and seine nets in 22 streams of 1st to 3rd order. Sampling resulted in 3035 specimens belong- ing to 117 species, 27 families and six orders. The most abundant species were Bryconops aff. melanurus, Hemigrammus belottii, and Hemigrammus analis. Four undescribed species were recognized, one of which is known only from the area of this study.

  • On the Trophic Organization of Fish Communities

Short term effects of 'Ificurui Dam (Amazonia, Brazil) on the trophic organization of fish communities Bernard de Mérona", Geraldo Mendes dos Santosb& Raimunda Gonçalves de Almeidac 'IRD, Centre de Cayenne, B.P 165, 97323, Cayenne Cedex, France (e-mail: merona@ cayenae.ird.j?) "INPA, CPBA., C.f?478, 69083, Manaus, Ani, Brazil UFRN Campus Universitário, 59000, Natal, Rn, Brazil Received 3 March 2000 Accepted 1August 2000 Key words: tropic, large river, resource availability, trophic structure, diet plasticity Synopsis A dam on a river course induces numerous changes in the aquatic environment both in the newly formed reservoir and in the river downstream. These changes modify the food resources available to fishes. As a consequence, fish communities undergo rapid transformations particularly in terms of trophic organization. Tucm' Dam, closed on the Tocantins River, Brazil, in September 1984, formed a large reservoir of approximately 220Okm'. Analyses of fish stomach contents were performed before and after the completion of the dam in the downstream section of the river as well as in the reservoir. Resource availability was seen through the relative contribution of food items in supporting the biomass. Main changes caused by the dam consisted of an increase in fishes as a food resource and of a parallel decrease of sediment both in the reservoir and in the downstream part of the river. In addition, in the downstream section, the relative contribution of plankton as a food resource diminished after dam closure. We identified 8 feeding regimes before dam closure.
