The colubrid snake Chironius fuscus (Colubridae) is a widely distributed species in South America, exhibiting a disjunct distribution associated to rainforests of Amazonia and Eastern Brazil (from Pernambuco to Paraná States). In this study, we present new distributional data from Paraná state and extend the known range to the state of Santa Catarina. We also present meristic and morphometric data of the southernmost populations of the species. © 2012 Check List and Authors.

After the description in the 19th century of two hummingbird species currently allocated to the genus Stephanoxis, Peters (1945) merged both taxa into a single species without providing any rationale. Here we re-evaluate the taxonomy and species limits of the representatives of this genus based on an extensive number of specimens. We demonstrate these taxa are better treated as full species under both the Biological and Phylogenetic Species Concepts due to their well-defined range and plumage patterns and reciprocally diagnosability. They have distinct, allopatric distributions segregated by a 160 km gap between the Serra do Mar, to the east, and Serra de Paranapiacaba, to the west, in the state of São Paulo. Stephanoxis species have ranges which are congruent with other montane bird species' suggesting shared vicariance events during preterit interglacial periods.

Bibimys is a genus still poorly known in its basic aspects, such as systematics, natural history and geographic distribution. In Brazil, only Bibimys labiosus is recorded, with occasional records spread in time and space. This paper presents four new localities of the species in Araucaria Forest, Parana state, extending its distribution 150 km southwards. Additionally, a map of the known distribution of the species in Brazil and in Araucaria Forest is provided. The records point toward the lack of knowledge about basic aspects of the small nonflying mammal fauna in the plateau regions of Brazil. © 2015 Check List and Authors.

The Brown-backed Parrotlet [Touit melanonotus (Wied, 1820)] is a rare forest species restricted to the Brazilian Atlantic Forest, and is included in the endangered category for species threatened of extinction. As there is a lack of knowledge about the species' natural history and occurrence, new observations can provide helpful information for parrotlet conservation. Here we reevaluate the first record for the species and present new records for the state of Paraná (southern Brazil). The vocalizations previously attributed to T. melanonotus, and which were used to infer its occurrence in the state, were examined by spectrogram analysis. These were actually found to be vocalizations of the Red-capped Parrot [Pionopsita pileata (Scopoli, 1769)], representing a case of misidentification. Even so, the Brown-backed Parrotlet occurs with some regularity in the state of Paraná, as shown by 12 records spread through seven localities spanning the entire Paraná coast. The Brown-backed Parrotlet was recorded mostly in lowland areas, and as these forest types suffer intense pressures, conservation efforts aiming the species preservation should focus in the maintenance of these habitats.

The increasing number of quantitative assessments of homogenization using citizen science data is particularly important in the Neotropics, given its high biodiversity and ecological peculiarity, and whose communities may react differently to landscape changes. We looked for evidence of taxonomic homogenization in terrestrial birds by investigating patterns of beta diversity along a gradient of human-altered landscapes (HAL), trying to identify species associated with this process. We analyzed bird data from 87 sites sampled in a citizen science program in the south Brazilian Atlantic Forest. Regional-scale taxonomic homogenization was assessed by comparing beta diversity among sites in different HALs (natural, rural or urban landscapes) accounting for variation derived from geographical distance and zoogeographical affinities by georeferencing sites and determining their position in a phytogeographical domain. Beta diversity was calculated by multivariate dispersion and by testing compositional changes due to turnover and nestedness among HALs and phytogeographical domains. Finally, we assessed which species were typical for each group using indicator species analysis. Bird homogenization was indicated by decreases in beta diversity following landscape changes. Beta diversity of rural sites was roughly half that of natural habitats, while urban sites held less than 10% of the natural areas beta diversity. Species composition analysis revealed that the turnover component was important in differentiating sites depending on HAL and phytogeography; the nestedness component was important among HALs, where directional species loss is maintained even considering effects of sampling effort. A similar result was obtained among phytogeographical domains, indicating nested-pattern dissimilarity among compositions of overlapping communities. As expected, a few native generalists and non-native urban specialists were characteristic of rural and urban sites. We generated strong evidence that taxonomic homogenization occurs in the south Brazilian Atlantic Forest as a result of a directional and nested species loss, with the resultant assemblages composed of few disturbance-tolerant birds.

Herein we provide a list of reptiles from Parque Estadual de Itapuã, a conservation unit of integral protection located in the municipality of Viamão, state of Rio Grande do Sul, southern Brazil and inserted in the domains of the Pampa Biome. The study was carried out from February 2003 to July 2004. We recorded 39 species: 23 snakes, eight lizards, four testudines, three amphisbaenians and one crocodilian. Through the knowledge of the species in the area, we justify the importance of preserving this important natural remnant. © 2012 Check List and Authors.

The reptile fauna of some localities in Paraná is still poorly known. Most surveys were conducted in the central-north, central-south, and eastern regions of the state. Herein, we present a list of squamate reptiles from the Mauá Hydroelectric Power Plant along the Tibagi River, in the central-east region of Paraná. Samplings occurred from March 2010 to April 2015. We recorded 34 species: 24 snakes, eight lizards, and two amphisbaenians. Our work adds new knowledge about the reptilian fauna of the central-east region of Paraná. © 2015 Check List and Authors.

Lists of reptiles of localities in Paraná are still scarce and restricted to three works, developed in the central-north and eastern regions of the state. Herein we present a list of reptiles of the Complexo Energético Fundão-Santa Clara, located in the central-south region of Paraná. The study was carried out from May 2010 to March 2012. We recorded 31 species: 20 snakes, seven lizards, two amphisbaenians and two testudines. We hope through this work contribute to a greater knowledge of the reptilian fauna of the central-south region of Paraná. © 2015 Check List and Authors.
