Unusual chromosome numbers and polyploidy in invasive fire ant populations
(Springer, 2021-08)
Fire ants (Solenopsis invicta Buren in J Ga Entomol Soc 7:1–26, 1972), an invasive alien ant species, first spread from South America to the United States in the 1930s, the southern part of the United States by the end of ...
Molecular systematic of three species of Oithona (Copepoda, Cyclopoida) from the Atlantic ocean: Comparative analysis using 28S rDNA
(Public Library of Science, 2012-04)
Species of Oithona (Copepoda, Cyclopoida) are highly abundant, ecologically important, and widely distributed throughout the world oceans. Although there are valid and detailed descriptions of the species, routine species ...
Cytogenetic studies in the redtail catfish, Phractocephalus hemioliopterus (Bloch & Schneider, 1801) (Siluriformes, Pimelodidae) a giant fish from Amazon basin
(Pensoft, 2017-03-06)
The objective of this study was to cytogenetically analyze Phractocephalus hemioliopterus comparing the findings with other data to infer relationships among Pimelodidae species. The results revealed a diploid number of ...
Cytogenetic studies in South American species of Serjania (Sapindaceae: Paullinieae)
(Taylor & Francis Ltd, 2012-12)
Serjania Mill. (Paullinieae) is considered the most important neotropical genus of Sapindaceae due to species number and its widespread distribution. In this study, 14 species belonging to three sections were analyzed using ...
PHB-degrading Streptomyces sp. SSM 5670: isolation, characterization and PHB-accumulation
(Drishti Offset, 2014-08)
New microbial bioprospecting has become an important way to find new polyhydroxyalkanoate (PHA) producers and degraders. Poly (3-hydroxybutyrate) (PHB), the best known member of the PHAs, has received much attention because ...
25S–18S rDNA IGS of Capsicum: molecular structure and comparison
(Springer, 2012-02)
The primary and secondary structures of the intergenic spacer (IGS) between the 3′-end of 25S ribosomal RNA (rRNA) gene and the 5′-end of 18S rRNA gene are described for the cultivated chili pepper Capsicum pubescens. The ...

(PeerJ Inc., 2018-05)
We describe a new anuran species of the genus Pseudopaludicola that inhabits sandy areas in resting as associated to the Atlantic Forest biome in the state of Espírito Santo, Brazil. The new species is characterized by: ...
Culture media and temperature influence on growth and sexual reproduction of the fish pathogens Achlya racemosa and Saprolegnia ferax
(Gebruder Borntraeger, 2011-02)
Two fungal parasites isolated from the fish Odontesthes bonariensis in Argentina were identified as Achlya racemosa and Saprolegnia ferax based on morphology and ITS rDNA sequence comparison. Studies were conducted to ...
Evaluation of a plasmid-based 16S–23S rDNA intergenic spacer region array for analysis of microbial diversity in industrial wastewater
(Elsevier Science, 2004-04)
A plasmid-based 16S–23S rDNA intergenic spacer region (ISR) array was developed and optimized for analysis of microbial diversity within complex environmental samples. Plasmid probes with 16S–23S rDNA ISR inserts (800-1500 ...
The life cycle of Magnivitellinum saltaensis n. sp. (Digenea: Alloglossidiidae) in Salta Province, Argentina
(Springer, 2021-06-06)
We describe the alloglossiid trematode Magnivitellinum saltaensis n. sp., a parasite of the characiform fish Psalidodon endy, and its life cycle from Salta, northwest of Argentina. This is the first life cycle described ...
