Testate amoebae have a great potential for use in scientific researches due to their ecological characteristics such as abundance, wealth, and generation time. In this way, this study aimed to present a scientometric analysis to describe the evolution of the different advances in researches on testate amoebae and identify a temporal pattern in this evolution. The literature review was based on papers indexed by Thomson Reuters (www.isiwebofknowledge.com) and SciVerse Scopus (www.scopus.com). In total 562 papers were examined. Results showed a pattern of evolution in scientific studies, most with ecological approach with descriptive and predictive designs. At the global level, researches on testate amoebae progressed in both the number of articles published... |

The blackfin goosefish is included in a prized fish category, representing valuable fishery resource worldwide. The aim of this study was to identify the Anisakidae larvae parasitizing this fish species, considering the hygienic-sanitary and public health importance of these parasites infecting specimens of the blackfin goosefish, Lophius gastrophysus Miranda-Ribeiro, 1915 (Lophiidae), purchased from markets in the municipalities of Cabo Frio, Niterói, Duque de Caxias and Rio de Janeiro; parasitological indices and sites of infection are presented. From March 2000 to December 2005, 87 specimens of Lophius gastrophysus were investigated for helminths. Seventeen fish (19.5%) were parasitized with larvae of anisakid nematodes. Anisakis simplex,... |

Lagoons are considered protected areas because these systems play a key ecological role. However, the extraction of macrophyte Schoenoplectus californicus is held for manufacture of handcrafts, being an alternative income for riverbank communities. This study evaluated the impact of S. californicus experimental cutting on benthic macroinvertebrates trough a field experiment. Macroinvertebrates were sampled at 1, 12, 26 and 60 days after the macrophyte cutting in demarked plots (1 m²), as well at control plots. The families number was not statistically different (ANOVA, p > 0.05), but the total density of invertebrates, and the density of Ceratopogonidae were significant (ANOVA, p < 0.05) for interaction between sampling date and treatment. A... |

The southern State of Rio Grande do Sul (RS) is the main rice producer in Brazil with a 60% participation of the national production and 86% participation of the region. Rice culture irrigation system is done by flooding, which leads to soil salinization, a major environmental constraint to production since it alters the plants’ metabolism exposed to this type of stress. The indica cultivar, widely used in RS, has a higher sensitivity to salinity when compared to that of the japonica cultivar in other physiological aspects. Current research analyzes enzymes expression involved in salt-subjected indica and japonica rice cultivars’ respiration. Oryza sativa L. spp. japonica S.Kato (BRS Bojuru, IAS 12-9 Formosa and Goyakuman) and Oryza sativa L. spp. indica... |

The goal of present study was to evaluate the effects of diabetes on quantitative parameters of Leydig cells. Twelve adults Wistar rats were divided in: 1) Diabetic Group (DG), which was induced by a single intraperitoneal injection of streptozotocin (60 mg kg-1 of body weight); and 2) Control Group (CG), which received citrate buffer intraperitoneal. After eight weeks of diabetic induction, the animals were weighted, anesthetized and testicles were removed and routinely processed to paraffin embedded. Body weight (40%) and testicular weight (18%) of diabetic rats were significantly lower than control group. Diabetic rats showed an increase in interstitial compartment but the tubular compartment did not differ. The individual volume of Leydig cells and... |

Periphytic algal community in artificial and natural substratum in a tributary of the Rosana reservoir (Corvo Stream, Paraná State, Brazil). This study evaluated the heterogeneity in periphytic algal community, under the influence of time colonization on artificial substratum. We also examined which abiotic variables most influenced the community in natural and artificial substratum. Egeria najas Planchon was used as natural substratum, and a plastic plant, as artificial. This experiment was carried out in a lateral arm from Rosana Reservoir, formed by Corvo Stream (Paranapanema river basin), in the period from November 21st to December 12nd, 2003, characterized as a warm and rainy period. Changes in species composition were assessed using the similarity... |

The objective of this study was to quantify argyrophillic, argentaffin and insulin immunoreactive endocrine cells in the different segments of the small intestine of Didelphis aurita and measure probable differences in the number of these cells between adult and post-pubertal animals. Biological material consisted of ten male and female opossums specimen, divided in two groups according to weigh. The utilized staining techniques were Grimelius, modified Masson-Fontana and direct immunoperoxidase. Results indicated a predominance of argyrophillic cells in the small intestine of opossums from class 1 and 2, with an average of 52.58 and 56.15 cells mm-2, respectively; of which, the average number of total endocrine cells, argyrophillic and argentaffin cells... |
