The present note extends the distribution of annual killifish Austrolebias periodicus, a endangered species, endemic of the Pampas region, in Ibicuí River basin, state of Rio Grande do Sul, southern Brazil. This information is needed to develop conservation strategies for this species and its habitat, which are at high risk due to the expansion of rice production and exotic forests in southern Brazil.

The two endemic, endangered species, Bacch­aris hypericifolia (Asteraceae) and Hypericum salvadorense (Hypericaceae), were known only for the Rio Grande do Sul state, in Brazil. In this paper we report two new occurrences of these species in Santa Catarina, expanding their geographic distribution to the north. Baccharis hypericyfolia and H. salvadorense were collected in areas of PPBio (Programa de Pesquisa em Biodiversidade) project. These novelties evidence the presence of knowledge gaps regarding the flora and little collecting effort in the grasslands from Southern Brazil.

<p>The Sinos River Basin (SRB) is located in the northeastern region of the state of Rio Grande do Sul (29º20' to 30º10'S and 50º15' to 51º20'W), southern Brazil, and covers two geomorphologic provinces: the southern plateau and the central depression. It is part of the Guaíba basin, has an area of approximately 800 km<sup>2</sup> and contains 32 counties. The basin provides drinking water for 1.6 million inhabitants in one of the most important industrial centres in Brazil. This study describes different water quality indices (WQI) used for the sub-basins of three important streams in the SRB: Pampa, Estância Velha/Portão and Schmidt streams. Physical, chemical and microbiological parameters assessed bimonthly using samples collected at each stream source were used to calculate the Horton Index (HI), the Dinius Index (DI) and the water quality index adopted by the US National Sanitation Foundation (NSF WQI) in the additive and multiplicative forms. These indices describe mean water quality levels at the streams sources. The results obtained for these 3 indexes showed a worrying scenario in which water quality has already been negatively affected at the sites where three important sub-basins in the Sinos River Basin begin to form.</p>

Abstract: The Brazilian Atlantic Forest is one of the world’s most biodiverse biomes, with large numbers of endemic and threatened species. However, this biome has suffered extensive deforestation and habitat fragmentation, with a drastic reduction of its original vegetation cover. The compilation of data on the occurrence patterns of anurans and their natural history is important for the development of effective conservation strategies. Here, we present the results of a survey of the anuran fauna of Parque Estadual do Papagaio Charão (PEPC) in Rio Grande do Sul state, southern Brazil, providing information on species endemism, conservation status, and reproductive modes. We collected data on the local anurans between March 2018 and February 2019 using active searches and pitfall traps. We recorded 26 anuran species distributed in seven families, with eight different reproductive modes. The largest number of species (20) was found at the forest edge, followed by the interior of the forest and open area, each with 16 species. The most abundant species were Leptodactylus plaumanni (41.7% of records), Physalaemus cuvieri (27.1%), and P. carrizorum (16.5%). Greater species richness and abundance were recorded during the rainier months, while temperature influenced only the abundance of the anurans. Rhinella henseli, Rhinella icterica, Vitreorana uranoscopa, Aplastodiscus perviridis, Boana curupi, Boana leptolineata and Proceratophrys brauni are all endemic to the Atlantic Forest. Melanophryniscus devincenzii is classified as Endangered by the IUCN, and Proceratophrys bigibbosa as Near Threatened. Boana curupi is considered to be Endangered in Rio Grande do Sul state, and Vulnerable in Brazil, while V. uranoscopa is Near Threatened in Rio Grande do Sul. Our findings emphasize the importance of protected areas, such as the PEPC, for the maintenance of anuran populations and communities in the Mixed Rainforest formations of southern Brazil.

The present study records for the first time the small cichlidae fish Laetacara dorsigera (Heckel, 1840) at Uruguay River basin and state of Rio Grande do Sul, southern Brazil, previously known from Amazon, Paraná and Paraguay River basins. Although the ichthyofauna of Uruguay River basin is relatively well known, this record suggests that there are still unexplored environments, such as wetlands, where there may be species not yet reported, and found in other hydrographic systems.
