  • 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.

  • Structure of Tropical River Food Webs Revealed by Stable Isotope Ratios
    OIKOS 96: 46–55, 2002 Structure of tropical river food webs revealed by stable isotope ratios David B. Jepsen and Kirk O. Winemiller Jepsen, D. B. and Winemiller, K. O. 2002. Structure of tropical river food webs revealed by stable isotope ratios. – Oikos 96: 46–55. Fish assemblages in tropical river food webs are characterized by high taxonomic diversity, diverse foraging modes, omnivory, and an abundance of detritivores. Feeding links are complex and modified by hydrologic seasonality and system productivity. These properties make it difficult to generalize about feeding relation- ships and to identify dominant linkages of energy flow. We analyzed the stable carbon and nitrogen isotope ratios of 276 fishes and other food web components living in four Venezuelan rivers that differed in basal food resources to determine 1) whether fish trophic guilds integrated food resources in a predictable fashion, thereby providing similar trophic resolution as individual species, 2) whether food chain length differed with system productivity, and 3) how omnivory and detritivory influenced trophic structure within these food webs. Fishes were grouped into four trophic guilds (herbivores, detritivores/algivores, omnivores, piscivores) based on literature reports and external morphological characteristics. Results of discriminant function analyses showed that isotope data were effective at reclassifying individual fish into their pre-identified trophic category. Nutrient-poor, black-water rivers showed greater compartmentalization in isotope values than more productive rivers, leading to greater reclassification success. In three out of four food webs, omnivores were more often misclassified than other trophic groups, reflecting the diverse food sources they assimilated. When fish d15N values were used to estimate species position in the trophic hierarchy, top piscivores in nutrient-poor rivers had higher trophic positions than those in more productive rivers.

Guabine, Hoplias malabaricus. [http://upload.wikimedia.org/wikipedia/commons/thumb/3/34/Hoplias_malabaricus1.jpg/800px- Hoplias_malabaricus1.jpg , downloaded 13 November 2012] TRAITS. The guabine, Hoplias malabaricus, is also known as wolf-fish or tahira in Trinidad and Tobago (Phillip & Ramnarine 2001). This freshwater fish can grow up to 40 cm in length and can weigh more than 1.5 kg (Kenny 2008). The shape is cylindrical and it has a large mouth since it is a predatory creature. The name wolf-fish was given to the guabine due to the presence of the dog-like teeth. When bitten, the jaws of this fish are locked onto the prey (Kenny 2008). The coloration of the guabine fish is usually dark brown or grey as seen in Fig.1 above with either darker vertical stripes or a single horizontal stripe on the body (Wikipedia, 2012) so that they can camouflage and hunt better. The fish can be identified and distinguished from other species by the shape of the under-jaw where a V-shape is formed when the inside jaw lines come to the front of the fish (Cousins 2011). The juvenile stages of the guabine resemble the adult forms with the exception of the size where the juveniles are more slender than the adults. According to Cousins (2011), the females have a bigger build than the males. UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour ECOLOGY.

Yarrow, Hoplerythrinus unitaeniatus. [http://inpn.mnhn.fr/espece/cd_nom/461169, downloaded 1 April 2015] TRAITS. A freshwater fish that grows to a maximum length of 25cm; males and females are alike. They have an elongated body shape with the mouth terminally positioned (Fig. 1). They have one dark lateral stripe along their body, one dorsal fin, one anal fin and paired pectoral and pelvic fins (Luna, 2015). Hoplerythrinus unitaeniatus is capable of aerial respiration (breathing air) as well as brachial respiration (in water, using gills) (Alkins, 1981). DISTRIBUTION. Hoplerythrinus unitaeniatus is distributed throughout the swamps, creeks and flooded savannas of South and Central America (Fig. 2). It has been located in Trinidad, Guyana, Suriname, São Francisco, French Guiana, Ecuador, Brazil, and Argentina (Mol, 2012). HABITAT AND ACTIVITY. Hoplerythrinus unitaeniatus is a freshwater fish that prefers waters with slow currents (Fig. 3). The yarrow can survive in temperatures of 23-27°C in a pH range of 5.6-7.8 (Luna, 2015). This fish is able to use oxygen in the air to respire, and can be UWI The Online Guide to the Animals of Trinidad and Tobago Ecology seen swimming to the surface to breathe. It can survive in water with low oxygen content and even out of water for prolonged periods of time (Mol, 2012). FOOD AND FEEDING. This fish is an omnivore feeding on mostly aquatic invertebrates and some fish (Luna, 2015).

  • Highlights Contrasting Karyotype Evolution Among Congeneric Species

Molecular Cytogenetics (2015) 8:56 DOI 10.1186/s13039-015-0161-4 RESEARCH Open Access Comparative cytogenetics in the genus Hoplias (Characiformes, Erythrinidae) highlights contrasting karyotype evolution among congeneric species Ezequiel Aguiar de Oliveira1,2, Luiz Antônio Carlos Bertollo1, Cassia Fernanda Yano1, Thomas Liehr3 and Marcelo de Bello Cioffi1* Abstract Background: The Erythrinidae fish family contains three genera, Hoplias, Erythrinus and Hoplerythrinus widely distributed in Neotropical region. Remarkably, species from this family are characterized by an extensive karyotype diversity, with 2n ranging from 39 to 54 chromosomes and the occurrence of single and/or multiple sex chromosome systems in some species. However, inside the Hoplias genus, while H. malabaricus was subject of many studies, the cytogenetics of other congeneric species remains poorly explored. In this study, we have investigated chromosomal characteristics of four Hoplias species, namely H. lacerdae, H. brasiliensis, H. intermedius and H. aimara. We used conventional staining techniques (C-banding, Ag-impregnation and CMA3 -fluorescence) as well as fluorescence in situ hybridization (FISH) with minor and major rDNA and microsatellite DNAs as probes in order to analyze the karyotype evolution within the genus. Results: All species showed invariably 2n = 50 chromosomes and practically identical karyotypes dominated only by meta- and submetacentric chromosomes, the absence of heteromorphic sex chromosomes, similar pattern of C-positive heterochromatin blocks and homologous Ag-NOR-bearing pairs. The cytogenetic mapping of five repetitive DNA sequences revealed some particular interspecific differences between them. However, the examined chromosomal characteristics indicate that their speciation was not associated with major changes in their karyotypes.
