“…So, the temporal changes in environmental characteristics in the site surveyed in the present study may be regarded as more remarkable, when compared to the homogeneous wetlands in southeastern Brazil [27] [28]. Interestingly, Fieker et al [32] found higher richness of waterbird species during the rainy season, but in grasslands that become much drier in the dry season and therefore do not provide suitable habitats for waterbirds, differently from what was observed in Ribeira lagoon. All in all, the seasonal patterns found in the present study highlight the influence of rainfall in waterbird assembly structure in coastal lagoons in southeastern Brazil.…”

We provide a list of bird species for Ribeira lagoon, a protected area in Rio de Janeiro, southeastern Brazil. Data were obtained in monthly surveys in points along a continuous transect, between August 2008 and July 2009, and 21 ad libitum observations. In total, 174 species were listed, including 121 land birds and 53 waterbirds. Of these, 11 are considered threatened at regional level. Waterbird richness was significantly higher in the dry season (April to September) than in the rainy season (October to March), whereas land bird richness remained constant. However, land bird richness varied throughout the year, with the highest value in February 2009 (77 species) and the lowest in May 2009 (41 species). The species listed account for 23% of the total of 745 bird species listed for Rio de Janeiro, and for 49% of 108 waterbirds recorded for the state.

“…Guildas são caracterizadas como um grupo de espécies que exploram a mesma classe de recursos ambientais, de modo semelhante (NUNES, 2010;FIEKER et al,2013). Segundo VERNER (1984), um número mínimo de guildas sugere que o ambiente encontra-se preservado, uma vez que este mantém um sistema o mais simples possível ao ponto de maximizar a quantidade de espécies por guilda.…”

“…Foi utilizado o princípio de guilda para verificar o índice de modificação no ambiente com base na utilização dos recursos pelas aves (NUNES, 2010;FIEKER et al, 2013). Oito guildas foram utilizadas para analisar o nível de impacto ambiental ao longo do córrego seguindo o modelo de NUNES (2010), são elas: Nectarívoros (nect), Necrófagos (necr), Carnívoros (ca), Onívoros (on), Frugívoros (fr), Granívoros (gr), Insetívoros (in) e Piscívoros (pi).…”

The environmental impact assessment when performed in anthropogenic environments contributes to development of public policies that minimize the impact of the man on the place. This is defined as a preventative tool environment management policies used to identify the degradation level in a certain place may or may not harm the environment. The avifauna is often used as bioindicator of environmental changes. Thus, the aim of this study was to evaluate the environmental impact of urbanization on stream Buriti, located in Tangara da Serra-MT, using birds as bioindicators. Five sampling points were selected. The first point was at the source; the second, a swamp; the third, where the stream enters São João; the fourth point, point of entry and the stream Paraíso; the fifth point, the river mouth, where the stream flows into the Buriti stream Estaca. The study resulted in a total of 351 birds observed, 20 species in 17 genera. The spring was the site of greatest abundance and richness of birds, with about 123 individuals of 11 species. Three and four points had the least amount of sampled individuals, 35 and 38 respectively. The collections showed a predominance of sparrows and parrots along the river, birds commonly found in urban environments, which shows that the stream has suffered some kind of change, mainly influenced by anthropic processes.

“…Species composition was compared to other areas of Cerrado within Sã o Paulo, namely: Botanical Garden/UNESP Reserve in Bauru (Cavarzere et al 2011), Canchim Farm in São Carlos (Manica et al 2010), UNESP Reserve in Corumbataí (Willis 2006), Itirapina Ecological Station (Willis 2004, Motta-Jú nior et al 2008, Fieker et al 2013, Itirapina Experimental Station , Jataí Ecological Station (Dias 2000), Cerrado Pé-de-Gigante/Vassununga State Park (Willis & Oniki 2003, Develey et al 2005, and UFSCar, campus Sã o Carlos (Motta-Jú nior 1990) ( Figure 1). Similarities (Jaccard's index) between areas were evaluated through the UPGMA clustering analysis with Euclidean distance matrix, using the R stats package (R Development Core Team 2008).…”

Birds at Santa Bárbara Ecological Station, one of the last Cerrado remnants in the state of São Paulo, Brazil

In the state of São Paulo, southeastern Brazil, the phytophysiognomy known as Cerrado takes less than 1% of its original cover. Thus, the establishment and management of protected areas are essential to save a significant sample of biodiversity of this environment in the region. The Santa Bárbara Ecological Station is one of the largest protected areas in São Paulo, and one of the few ones to cover a mosaic with most of the vegetation types of Cerrado. This article aims to increase the knowledge of avifauna in the reserve, showing new bird records and evaluating the association of species to their physiognomies. We carried out surveys from 2008 to 2013, which resulted in the record of 226 species, or 246 when in regard to Willis & Oniki’s works (1981, 2003). Twenty-two are regionally threatened, and five globally threatened. Despite showing lower species richness, grasslands stood out because of the number of species of conservation concern. Preventing the densification of woody vegetation and controlling the invasion of alien plants are important management actions for the conservation of the bird assemblages at Santa Bárbara reserve, one of the last open Cerrado remnants in São Paulo.
