The systematics of the species included by STICHEL (1910) in his Cinericiifonnes section of the genus Audre Hemming, 1934 are reviewed. "Audre" guttata jaibensis, ssp.n., is described from northern Minas Gerais. The synonomizing of two taxa described by Schweitzer & Kaye, Hamearis precaria Schweitzer & Kaye, 1941, and H. precaria ab. similis Schweitzer & Kaye, 1941, with "Audre" cinericia is explained. Descriptions of the habitat and adult behavior of "Audre" guttata jaibensis are provided. |

This work studies the acute contact toxicity of oxalic acid (OA) on a honeybee polyhybrid subspecies (Apis mellifera), which is the dominant biotype in southwestern zone of Uruguay (SWZU) and the country's most important honey-producing region. We determined the mean lethal dose (LD50), as well as the no observed effect level (NOEL) and the lowest observed effect level (LOEL) values. We also estimated the total number of honeybees per hive in the test area. The aim was to assess the relationship between the maximum OA dose used in Uruguay (3.1 g OA per hive) and the toxicological parameters of honeybees from SWZU. The current dose of 3.1 g OA per hive corresponds to 132.8 OA per honeybee since determined NOEL is 400 OA per honeybee; our results indicate... |

ABSTRACT We provide an updated list of the vascular epiphytic flora occurring in native environments of Uruguay based on literature review, herbarium specimens, and fieldwork throughout the country. The catalogue provides standardized information for each species, including accepted name, synonyms used within Uruguay, epiphytic category, distribution within the country, habitat, conservation status, observations, and a voucher citation. The effort documented 73 species for the epiphytic flora of Uruguay (3 % of the flora), distributed among 29 genera and 12 families. Bromeliaceae was the richest family (17), followed by Polypodiaceae (16) and Orchidaceae (12). Tillandsia stood out as the most speciose genus with 15 species. Characteristic holoepiphytes was... |

El presente artículo es una aproximación a la situación laboral y jurídica de los afrodescendientes, esclavizados y libertos, en la frontera uruguayo-brasileña, en la segunda mitad del siglo XIX, particularmente en lo que hace a su captura y secuestro para ser vendidos como mano de obra esclavizada cuando ya estaba abolida la esclavitud en el Uruguay. A diferencia del proceso de liberación ocurrido en Montevideo y sur uruguayo, la persistencia de mano de obra servil, ya sea como esclavos reconocidos en su condición de tal o como peones contratados, formulismo legal adoptado para disfrazar su condición de esclavizados ante las leyes uruguayas, persistió hasta finales del siglo XIX en las estancias de la frontera norte y este de ese país. Con el fin del... |

The diet of Leptodactylus ocellatus (L., 1758) was studied in specimens collected at Maldonado Department (Uruguay), where monthly surveys were made between August 1998 and March 2000. A total of 143 frogs were collected, measured, sexed, and dissected, to assess stomach contents. The anurans were grouped into three age classes and four categories (considering sex and capture date). The trophic amplitude for each age class and sex-season category was quantified using Shannon-Weaver Index, and the trophic niche overlap between ages and categories by using the Pianka Index. Comparisons among treatments were made by G-tests. The most important prey items were coleopterans (IRI = 2547), and significant correlations were found between predator and prey sizes.... |

RESUMEN. Smicridea McLachlan (Trichoptera: Hydropsychidae) es el único género de Smicrideinae que se ha encontrado en la región Neotropical. De las 90 especies de tricópteros citadas para el Uruguay, sólo dos pertenecen a Smicridea: Smicridea (Rhyacophylax) atrobasis Flint y Smicridea (Rhyacophylax) dentifera Flint. En el presente trabajo se citan siete especies: Smicridea (R.) coronata Flint, Smicridea (R.) discalis Flint, Smicridea (R.) mesembrina (Navás), Smicridea (R.) pampeana Flint y Smicridea (R.) spinulosa Flint, citadas por primera vez para el Uruguay; S. (R.) atrobasis y S. (R.) dentifera, ampliando su distribución a los departamentos de Paysandú y Salto. Además, se ilustran los genitales masculinos de S. (R.) atrobasis, S. (R.) coronata y S.... |
