Cascadu, Flat-Head Or Chato
UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour Callichthys callichthys (Flat-head Cascadu or Chato) Family: Callichthyidae (Plated Catfish) Order: Siluriformes (Catfish) Class: Actinopterygii (Ray-finned Fish) Fig. 1. Flat-head cascade, Callichthys callichthys. [“http://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=335”, Downloaded 10th October 2011] TRAITS. Was first described by Linnaeus in 1758 and was named Silurus callichthys. They generally reach a maximum length of 20 cm and can weigh up to 80g.(Froese and Pauly, 2001) The females are generally larger and more robust as compared to the males. The Callichthys callichthys is an elongated catfish with a straight or flattened belly profile. It also has a broad flattened head and a body which is almost uniform in breath with some posterior tapering which beings after dorsal fin. (Figure 2) Its body consists of 2 rows of overlapping plates or scutes. Approximately 26 – 29 scutes seen on the upper lateral series and 25 – 28 scutes seen on the lower lateral series. The fins are rounded and the fish also has a total of 6-8 soft dorsal rays. It also has 2 pairs of maxillary barbles near its mouth and small eyes. The fish has an inferior type mouth ( Berra, 2007). The Callichthys callichthys is dark olive green in colour to a grey brown as seen in Figure 1, with the males having a blue to violet sheen on its flanks. ECOLOGY. Callichthys callichthys is a freshwater organism which is primarily riverine in habitat (Arratia, 2003). Only 2 families of catfishes are found to colonise marine habitats UWI The Online Guide to the Animals of Trinidad and Tobago Behaviour (Arratia, 2003). -

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. -
Direct and Indirect Effects of the Guppy, Poecilia Reticulata, on the Structure and Function of Stream Ecosystems in the Norther
DIRECT AND INDIRECT EFFECTS OF THE GUPPY, POECILIA RETICULATA, ON THE STRUCTURE AND FUNCTION OF STREAM ECOSYSTEMS IN THE NORTHERN RANGE MOUNTAINS OF TRINIDAD by TROY NATHANIEL SIMON (Under the Direction of Catherine M. Pringle) ABSTRACT We are currently in the middle of the sixth mass extinction, thus predicting the ecological consequences of species loss from communities is a high priority research topic. Additionally, characterizing the ecosystem impact of macroconsumers has strong conservation implications, given the global trend in biodiversity loss toward higher trophic levels. The goal of this dissertation was to use Trinidadian guppies in the mountain streams of Northern Trinidad as a model system to explore several potentially important direct and indirect ecosystem effects of macroconsumers, which we have little understanding of in natural systems. This collection of studies utilizes both localized exclusion of macroconsumers using underwater electric fences within pools, as well as the natural reach-scale exclusion of guppies above and below barrier waterfalls to examine the ecosystem-level effects of macroconsumers. Results show that local adaptation of guppy populations, to the absence of large piscivores in higher elevation streams, shifted their top-down effects from reducing macroinvertebrate standing stock biomass, to reducing primary producer standing stock biomass. Additionally, the consumptive and non-consumptive effects guppies had similar but opposing effects on algal growth and biomass, which resulted in strong treatment effects from excluding guppies on primary algae. Finally, the loss of omnivorous guppies from a macroconsumer assemblage can alter the strength of top down effects of the remaining macroconsumer community on an important ecosystem-level process at both local- and landscape-scales. -

Animal Biodiversity and Conservation, 38.2: 241–252, Doi: https://doi.org/10.32800/ abc.2015.38.0241 Abstract A new species of Bryconamericus (Characiformes, Stevardiinae, Characidae) from the Pacific coast of northwes- tern Ecuador, South America.— A new species of Bryconamericus (Characiformes, Characidae, Stevardiinae) is described from the Pacific coast of northwestern Ecuador, South America. The new species is distinguished from all congeners by the presence in males of bony hooks on the caudal fin rays (vs. absence). The different layers of pigment that constitute the humeral spots have differing degrees of development and structure that are independent of each other. Brown melanophores are distributed in a thin, vertical, superficial layer of the epithelium (layer 1) and in another deeper (layer 2) that overlaps the first and is centered over the lateral–line. B. ecuadorensis has a horizontally oval or elliptical shape layer 2 pigment in the anterior humeral spot (vs. a rectangular or circular layer 2). The new species further differs in having an anterior extension of the caudal peduncle spot (vs. no anterior extension of the caudal peduncle spot) and by having a dark lateral stripe overlaid by the peduncular spot and by the regularly distributed pigmentation on scales on the sides of the body (vs. -

Alburnoides emineae, from Beyazsu Stream (south-eastern Euphrates River drainage), is distinguished from all species of Alburnoides in Turkey and adjacent regions by a combination of the following characters (none unique to the species): a well developed ventral keel between pelvic and anal fins, commonly scaleless or very rarely 1–2 scales covering the anterior portion of the keel; a deep body (depth at dorsal-fin origin 31–36% SL); 37–43 + 1–2 lateral-line scales, 13½–15½ branched anal-fin rays; number of total vertebrae 41–42, modally 41, comprising 20–21 abdominal and 20–21 caudal vertebrae. Alburnoides velioglui, from Sırlı, Karasu, Divriği and Sultansuyu streams (northern and northeastern Euphrates River drainages), is distinguished by a poorly developed ventral keel, completely scaled; a moderately deep body (depth at dorsal-fin origin 24–29% SL); 45–53 + 1–2 lateral-line scales, 11½ –13½ branched anal-fin rays; number of total vertebrae 41–42, modally 42, comprising 20–22 abdominal and 20–21 caudal vertebrae. -
Reconstruction of Oligocene and Neogene Freshwater Fish Faunas—An Actualistic Study on Cypriniform Otoliths
Reconstruction of Oligocene and Neogene freshwater fish faunas—an actualistic study on cypriniform otoliths TANJA SCHULZ−MIRBACH and BETTINA REICHENBACHER Schulz−Mirbach, T. and Reichenbacher, B. 2006. Reconstruction of Oligocene and Neogene freshwater fish faunas—an actualistic study on cypriniform otoliths. Acta Palaeontologica Polonica 51 (2): 283–304. Fossil utricular otoliths (= lapilli) from cypriniform fishes have long been recorded from European Oligocene and Neo− gene freshwater and oligohaline sediments. Until now, their determination was limited to the family level owing to the lack of morphological investigations on lapilli of Recent cypriniforms. The present study introduces a terminology for the lapillus morphology that is based on the lapilli of 134 specimens of 20 cyprinid and one balitorid species. It is demon− strated that the lapillus has valuable characters for taxonomic classification. As a result, fossil lapilli from Oligocene and Miocene continental deposits from the western Mediterranean, the Swiss and the South German Molasse Basin, the Mainz Basin, and additionally from Anatolia could be determined. Nine species were identified: aff. Abramis sp. vel aff. Alburnus sp., aff. Alburnoides sp., aff. Barbus sp., cf. Leuciscus sp., Palaeoleuciscus sp., Palaeotinca moeddeni sp. nov., Palaeotinca sp. 1, aff. Phoxinus sp., and aff. Rutilus sp. vel aff. Scardinius sp. Our study includes the oldest record of a Phoxinus−related and a Palaeotinca species from Europe. Additionally, aff. Abramis sp. vel aff. Alburnus sp. and aff. Alburnoides have been identified as fossils for the first time. The determination of the fossil lapilli has been supported by means of pharyngeal teeth, with the exception of aff. Abramis sp. -
