Abstract: The repeated evolution of novel life histories correlating with ecological variables offer opportunities to test scenarios of convergence and determinism in genetic, developmental, and metabolic features. Here we leverage the diversity of aplocheiloid killifishes, a clade of teleost fishes that contains over 750 species on three continents. -

The Catalog of Fishes database (http://research.calacademy.org/ichthyology/catalog) on which this study is based, has been maintained for 25 years and includes information on more than 50,000 available species names of fishes, with more than 31,000 of them currently regarded as valid species. New marine species are being described at a rate of about 100–150 per year, with freshwater numbers slightly higher. In addition, over 10,000 generic names are available ones of which 3,118 are deemed valid for marine fishes (as of Feb. 19, 2010). This report concentrates on fishes with at least some stage of their life cycle in the sea. The number of valid marine species, about 16,764 (Feb. -

These species are considered closely related to M. dapazi from the same region, with which they share the presence of a rudimentary interarcual cartilage and a dark reddish brown distal margin on the male anal fin. The group comprising M. dapazi and the three new species is here named as the M. dapazi species group.

Taxonomy of the Seasonal Killifish Genus Neofundulus in the Brazilian Pantanal (Cyprinodontiformes: Rivulidae)
65 (1): 15 – 25 © Senckenberg Gesellschaft für Naturforschung, 2015. 4.5.2015 Taxonomy of the seasonal killifish genus Neofundulus in the Brazilian Pantanal (Cyprinodontiformes: Rivulidae) Wilson J.E.M. Costa Laboratory of Systematics and Evolution of Teleost Fishes, Institute of Biology, Federal University of Rio de Janeiro, Caixa Postal 68049, CEP 21944-970, Rio de Janeiro, Brasil; wcosta(at)acd.ufrj.br Accepted 19.ii.2015. Published online at www.senckenberg.de / vertebrate-zoology on 4.v.2014. Abstract On the basis of fish collections made between 1991 and 2014, four species of the seasonal killifish genusNeofundulus are reported to occur in the Brazilian Pantanal, Paraguay river basin: N. parvipinnis, endemic to the Cuiabá and São Lourenço river drainages, in the northern portion of the Pantanal; N. rubrofasciatus, new species, from the Miranda river drainage, N. aureomaculatus, new species, from the Aqui- dauana river drainage, both in the south-eastern portion of the Pantanal; and N. paraguayensis, occurring in the Paraguay and Nabileque river floodplains, in the southern part of the Pantanal. The new species are diagnosed by unique colour patterns, and a combination of morphological characters states indicating that they are more closely related to N. parvipinnis and N. splendidus than to N. paraguayensis. Key words Aplocheiloid killifishes, Biodiversity, Pantanal wetland, Paraguay river, Systematics. Introduction The Brazilian Pantanal, also known as Pantanal de Mato Neofundulus has been known for a few papers in Grosso, is a vast wetland region, about 140,000 km2, the scientific literature. Until 1988, knowledge about comprising a tectonic depression along the left margin Neofundulus was restricted to the original descriptions of the Paraguay river. -

If any one can help him that would be great. There is some news on the killifish front which may interest some. There are several new specie names and a few new discoveries. News New classification and species names Five new South American Annuals have been described. These are Cynopoecilus fulgens, C. intimus, C. nigrovittatus and C. multipapillatus. A Nematolebias papilliferus has also been described. The genus Nematolebias has also been redefined and now only contains Nematolebias papilliferus and whitei.

Effects of Deforestation on Headwater Stream Fish Assemblages in the Upper Xingu River Basin, Southeastern Amazonia

Our goal was to test the hypotheses that deforestation affects the abundance, richness, and taxonomic structure of headwater stream fish assemblages in the Upper Xingu River Basin, in Southeastern Amazonia. Standardized sampling surveys in replicated first order streams demonstrated that deforestation strongly influences fish assemblage structure. Deforested stream reaches had twice the fish abundance than reference stream reaches in primary forests. These differences in assemblage structure were largely driven by increases in the abundance of a handful of species, as no influence of deforestation on species richness was observed. Stream canopy cover was the strongest predictor of assemblage structure, possibly by a combination of direct and indirect effects on the provision of forest detritus, food resources, channel morphology, and micro-climate regulation. Given the dynamic nature of change in land cover and use in the region, this article is an important contribution to the understanding of the effects of deforestation on Amazonian stream fish, and their conservation.

Trophic Strategy of Atlantirivulus Riograndensis (Cyprinodontiformes: Rivulidae), a Non-Annual Rivulid Threatened by Extinction, in a Perennial Environment, Brazil)
Neotropical Ichthyology, 14(1): e150068, 2016 Journal homepage: www.scielo.br/ni DOI: 10.1590/1982-0224-20150068 Published online: 14 April 2016 (ISSN 1982-0224) Trophic strategy of Atlantirivulus riograndensis (Cyprinodontiformes: Rivulidae), a non-annual rivulid threatened by extinction, in a perennial environment, Brazil) Laísa Wociechoski Cavalheiro and Clarice Bernhardt Fialho1 Rivulidae includes non-annual fish of perennial habitats and annual fish of temporary wetlands. The objective of this research was to investigate the trophic strategy of Atlantirivulus riograndensis in a perennial environment. Sampling occurred in an environmental conservation unit in the Pampa biome, Brazil. Quantification of the diet followed the volumetric method. Consumption of autochthonous material as the main food source of the species followed the pattern of Rivulidae. Species is zooplanktonic when young. Food spectrum is broadened and insectivorousness increases with ontogeny, revealing a specialist trend in the feeding strategy of A. riograndensis. The most diverse feeding occurs in the spring and summer seasons in which the presence of larger fish was more frequent than in other seasons. The increased consumption of microcrustaceans in the fall was related to smaller individuals, captured in greater quantities in this post-reproductive period. The lowest diversity of dietary items occurs during the winter and may reflect the lower diversity of food resources available in this season or the transition from juvenile to adult diet, with consumption of autochthonous Diptera by medium sized fish. Rivulidae inclui peixes não anuais de habitats perenes e peixes anuais de alagados temporários. O objetivo desta pesquisa foi investigar a estratégia trófica de Atlantirivulus riograndensis em um ambiente perene. -

Abstract Melanorivulus rubroreticulatus, new species, is described on the basis of material collected in the lower section of the Xingu river drain- age, Brazilian Amazon. It is a member of a group endemic to the region encompassing the southern Amazonas river tributaries and the Parnaíba river basin. The new species is distinguished from other congeners of this group by the presence of broad red bars on the caudal fin in males, bars often interconnected to form reticulations, and short red bars contrasting with intense light blue ground colour on the anal-fin base. It represents the northern-most record for the group, besides being the only species occurring in the Amazon rain forest and possibly is also the smallest one, barely surpassing 25 mm of standard length. Key words Amazon forest, Biodiversity, Killifish, Systematics, Taxonomy. Introduction Melanorivulus COSTA, 2006 is a killifish genus compris- ron-like pattern with vertex below body midline. Here ing over 40 small species occurring in a vast portion of we describe a new species of this group collected in the tropical South America (COSTA, 2011).
