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. -

Xiphophorus Hellerii Yucatan
Xiphophorus hellerii Yucatan In 1975 the Berlin aquarist Günter Daul collected during a holiday trip in Mexico some swordtails in the state of Quintana Roo and brought them to his homeplace successfully. This strain was called later erronously Xiphophorus hellerii Yucatan. However, the state of Yucatan is located west of Quintana Roo. Thus the strain should be named correctly Xiphophorus hellerii Quintana Roo; but the fish has been illustrated so often in the aquarium literature under the name of Xiphophorus hellerii Yucatan that a correction would lead only to unnecessary confusion. For all who are interested in the history of the fish we suggest the (German written) article: Wagenknecht, U. (2012): Der Yucatan-Schwertträger. Viviparos 1/2012: 26-29 (online here: http://www.lebendgebaerende- aquarienfische.de/media/files/Wagenknecht%20(2012)%20Der%20Yucatan-Schwerttraeger.pdf). It is very interesting that this population has survived as a pure strain now for 38 years in the tanks of hobbyist. The genetics of this polychromatic variety are also very interesting. There do exist rather yellow-bellied females and rather white-bellied females. If one crosses a male that has much red colours with a yellow-bellied female, the offspring is pure red males and yellow-bellied females. If one crosses a rather blue-green male of the strain with a white-bellied females, they also breed pure. However, hobbyists usually breed with mixed schools to preserve the genetic variability of the strain. Occasionally we have this interesting variety of wild swordtail as German bred in stock. For our customers: the fish have code 476753 on our stocklist. -
Species Composition and Invasion Risks of Alien Ornamental Freshwater
www.nature.com/scientificreports OPEN Species composition and invasion risks of alien ornamental freshwater fshes from pet stores in Klang Valley, Malaysia Abdulwakil Olawale Saba1,2, Ahmad Ismail1, Syaizwan Zahmir Zulkifi1, Muhammad Rasul Abdullah Halim3, Noor Azrizal Abdul Wahid4 & Mohammad Noor Azmai Amal1* The ornamental fsh trade has been considered as one of the most important routes of invasive alien fsh introduction into native freshwater ecosystems. Therefore, the species composition and invasion risks of fsh species from 60 freshwater fsh pet stores in Klang Valley, Malaysia were studied. A checklist of taxa belonging to 18 orders, 53 families, and 251 species of alien fshes was documented. Fish Invasiveness Screening Test (FIST) showed that seven (30.43%), eight (34.78%) and eight (34.78%) species were considered to be high, medium and low invasion risks, respectively. After the calibration of the Fish Invasiveness Screening Kit (FISK) v2 using the Receiver Operating Characteristics, a threshold value of 17 for distinguishing between invasive and non-invasive fshes was identifed. As a result, nine species (39.13%) were of high invasion risk. In this study, we found that non-native fshes dominated (85.66%) the freshwater ornamental trade in Klang Valley, while FISK is a more robust tool in assessing the risk of invasion, and for the most part, its outcome was commensurate with FIST. This study, for the frst time, revealed the number of high-risk ornamental fsh species that give an awareness of possible future invasion if unmonitored in Klang Valley, Malaysia. As a global hobby, fshkeeping is cherished by both young and old people. -

Brown (Head of Department) August 2004 Major Subject: Wildlife and Fisheries Sciences iii ABSTRACT The Role of Piscivores in a Species-Rich Tropical River. (August 2004) Craig Anthony Layman, B.S., University of Virginia; M.S., University of Virginia Chair of Advisory Committee: Dr. Kirk O. Winemiller Much of the world’s species diversity is located in tropical and sub-tropical ecosystems, and a better understanding of the ecology of these systems is necessary to stem biodiversity loss and assess community- and ecosystem-level responses to anthropogenic impacts. In this dissertation, I endeavored to broaden our understanding of complex ecosystems through research conducted on the Cinaruco River, a floodplain river in Venezuela, with specific emphasis on how a human-induced perturbation, commercial netting activity, may affect food web structure and function. I employed two approaches in this work: (1) comparative analyses based on descriptive food web characteristics, and (2) experimental manipulations within important food web modules.
