Última EFECTOS ECOTOXICOLOGICOS DEL CARTAP SOBRE POECILIA RETICULATA "GUPPY'' (POECILIDAE) Y PARACHEIRODON INNESI "NEON TETRA'' (CHARACIDAE) Gayana Iannacone,Jose; Onofre,Roxana; Huanqui,Olga. Se evaluó el impacto ecotoxicológico del insecticida carbámico cartap (1,3 di (carbamoytio)-2-dimetiloaminopropano) usado para el control de plagas agrícolas y como molusquicida de vectores de importancia en Salud Pública, sobre dos especies de peces del ecosistema acuático continental: Poecilia reticulata (Peters 1859) "guppy" (Poecilidae) y Paracheirodon innesi (Myers 1936) ``Neon Tetra" (Characidae). Ellos fueron utilizados como organismos no destinatarios en ensayos de corta duración, para determinar el impacto toxicológico del cartap. Para ambas especies de peces se evaluó el porcentaje de mortalidad, y dos respuestas subletales: el incremento del movimiento opercular y el nado extraño. A 3 h de exposición para P. reticulata, se encontró un valor de... Tipo: Journal article Palavras-chave: Bioensayo; Cartap; Insecticida; Paracheirodon; Poecilia.

A new species of the genus Poecilia Bloch & Schneider, 1801 is recorded from El Salvador. Morphological and meristic data of P. marcellinoi n. sp. and of the sympatric P. salvatoris Regan, 1907 are analysed. Intra- and interspecific variation are compared and correlated with environmental and interspecific influences. A high degree of character displacement is observed in populations from stable freshwater habitats. In habitats with presumed marine influences, this character displacement is counteracted by ecological stress. Based on the evidence presented, subspecific separation of observed ecotypes from literature is rejected.

Ano: 1995 URL: http://www.repository.naturalis.nl/record/504455 Molecular and taxonomic characterisation of introduced specimens of Poecilia reticulata in the lower Paraguay River basin (Cyprinodontiformes: Poeciliidae) Neotropical Ichthyology Rosso,Juan J.; Rosso,Franco del; Mabragaña,Ezequiel; Schenone,Nahuel F.; Avigliano,Esteban; Astarloa,Juan M. Díaz de. ABSTRACT Poeciliids comprise around 300 species inhabiting the fresh and brackish waters of the Americas and Africa. Poecilia reticulata is native to Northeastern South America and Trinidad and Tobago. In this paper, introduced specimens of P. reticulata collected in the lower Paraguay River in Argentina, were characterized by means of molecular and taxonomic approaches. We further explore, by means of DNA Barcoding, the singularity of the genetic identity of these specimens. Ocurrence of P. reticulata in the lower Paraguay River represents the first record of this species in Argentina. Thirteen individuals of P. reticulata were collected. DNA barcoding showed that all five specimens sampled belong to a single mitochondrial lineage, which was also present...
