| In the Cerrado, veredas are linear physiognomies that occur on hydromorphic soil usually along narrow water courses. They often growth on flat terrain or near headwaters. They are characterised by the abundance of buriti palms (Mauritia flexuosa) that growth over other trees, numerous shrubs and a dense herbaceous stratum. Despite being common landscape elements through the Cerrado's extension, the use of veredas by birds has not been examined in detail. This study aimed to review studies of birds and veredas in the Cerrado. Publications (n = 25) reported the use of veredas by 261 bird species. Only 13 of them had aspects of their biology (reproduction and feeding) studied in detail. Veredas are poorly used by Cerrado's endemic species, but are the major... |

| Abstract: Herein, we provide the first comprehensive amphibian checklist for the State of Tocantins, North of Brazil, based on field sampling, literature data, and specimens deposited in zoological collections. We performed field surveys from 2012 to 2019 in 12 Tocantins municipalities, totaling 376 days of sampling effort. We analyzed 25 papers from the literature and examined 1311 specimens from collections and collected 750 during field surveys. We recorded 90 amphibian species distributed in 12 anurans and two caecilians families. At least seven undescribed species along the state were recorded. We also present new records for 20 species for the state, nine of them corresponding to Amazonian species, four Cerrado endemic, one Caatinga species, and the... |

| 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,... |

| Abstract Amphibian research has grown steadily in recent years in the Amazon region, especially in the Brazilian states of Amazonas, Pará, Rondônia, and Amapá, and neighboring areas of the Guiana Shield. Even so, few data are available for the Amazonian savannas of Brazil. To contribute to the understanding of the diversity of the amphibians of these savannas, we surveyed 15 temporary ponds, six located in open areas, seven on the edge of savanna forest, and two within the forest, in the savanna of the Rio Curiaú Environmental Protection Area (EPA) in Macapá, in the state of Amapá, northern Brazil. Sampling occurred from May 2013 to August 2014 during periods when the ponds contained water. Amphibians were sampled through visual and auditory surveys... |

| Abstract Fire management is an important issue in the Brazilian Cerrado, since both anthropogenic high intensity fires and complete fire suppression can reduce the biodiversity in this biome. In this paper, we highlight the trends in scientific literature about fire effects in the Cerrado, aiming to detect possible gaps and to indicate directions of future scientific research. We searched for articles in the periodic database Web of Knowledge from 1991 to 2016, and observed an increase in the number of publications throughout the years. Most articles were associated with Brazilian institutions (58%), followed by those with collaboration between Brazilian and international institutions (33%), and those published by authors exclusively from international... |

| Abstract Species inventories are important tools to evaluate biodiversity losses and contribute to the conservation of endangered areas. The Amazon and Cerrado are the largest Brazilian biomes and represent some of the most threatened regions of the country. Due to its location between these biomes, the state of Maranhão, Northeast Brazil, possesses a great variety of habitats and a high local diversity. Nonetheless, few faunistic inventories of diversified groups have been performed in the state. In the specific case of butterflies, a well-known biological indicator, no inventories have been published in the past years. This study aimed to expand the knowledge on the composition of butterflies in Amazon and Cerrado remnants of Maranhão. Butterflies were... |

| Information on the cerrado vascular flora of the municipality of Bauru has been provided in lists of floristic surveys carried out in fragments of this vegetation type at different times, applying different criteria, and conforming to current taxonomic classifications. We organized this information according to APG III and revised synonymies, aiming at producing a single floristic list of species occurring in cerrado sensu lato or ecotonal areas (transitions between cerrado and seasonal forest) in municipality of Bauru to inform conservation proposals. For this purpose, we referred to all floristic lists of vascular plants found in cerrado fragments in Bauru and to botanic material collected and deposited in the herbaria of the Department of Biological... |

| A natural vegetation area, with 1269 ha, composed mainly by cerrado, located at Santa Rita do Passa Quatro Municipality, São Paulo State, southeastern Brazil (21°36-39'S, 47°36-38'W), was studied. From September 1995 to February 1997, a floristic survey was carried out, when all vascular plant species at reproductive stage were collected. The flowering and fruiting patterns of the community were studied, comparing the herbaceous and the woody species. In the herbaceous component, 239 species were found and, in the woody one, 108 species. The woody species flowered mainly at the beginning of the rainy season, while the herbaceous ones produced flowers generally at the end of that season. The proportion of anemo and autochorous species was greater in the... |
