Breeding sites of drosophilids (Diptera) in the Brazilian Savanna. I. Fallen fruits of Emmotum nitens (Icacinaceae), Hancornia speciosa (Apocynaceae) and Anacardium humile (Anacardiaceae) Rev. Bras. entomol.
Roque,Francisco; Hay,John Du Vall; Tidon,Rosana.
In this study, drosophilids that bred in fruits of three common plant species of the Brazilian Savanna were investigated: Emmotum nitens, Hancornia speciosa and Anacardium humile, along with the temporal and spatial distribution of these insects among fruits obtained from six individuals of E. nitens. Fallen fruits were collected in natural environments, placed on moist sand in individual containers and all drosophilids that emerged from these resources during 15 days were collected, counted and identified. From 3,651 fruits collected (3,435 of E. nitens, 179 of A. humile and 37 of H. speciosa) 4,541 flies emerged and were classified into 19 species of Drosophilidae. Their distribution was unequal among the three resources, also over time, and among the...

Gavilan,Natália Helena; Furlan,Fernanda Cardoso; Zorz,Alex Zichner; Oliveira,Leandro Silva de; Campos,Wellington Ferreira; Brondani,Gilvano Ebling.
ABSTRACT: Cochlospermum regium roots are used in popular medicine and its extract has diverse phytochemical molecules some with antimicrobial activity, consequently exposing this specie to genetic erosion risks. Thus, the objective of this study was to develop an in vitro multiplication protocol using chemical sterilization of culture medium. Therefore, explants obtained from apical buds of C. regium seedlings were inoculated into with 0.05mg L-1 NAA and 1mg L-1 BAP sterilized by chemical agent sodium hypochlorite (NaOCl) at 0.001%, 0.003% and 0.005% of active chlorine (Cl). Autoclaved culture medium was used as control. Result showed that the contamination by bacterial at 91 days of cultivation was significantly (P<0.05) controlled by autoclaving,...

First record of Chrysomya rufifacies (Macquart) (Diptera, Calliphoridae) from Brazil Rev. Bras. entomol.
Silva,José O. de Almeida; Carvalho-Filho,Fernando da S.; Esposito,Maria C.; Reis,Geniana A..
First record of Chrysomya rufifacies (Macquart) (Diptera, Calliphoridae) from Brazil. In addition to its native fauna, the Neotropical region is known to be inhabited by four introduced species of blow flies of the genus Chrysomya. Up until now, only three of these species have been recorded in Brazil - Chrysomya albiceps (Wiedemann), Chrysomya megacephala (Fabricius), and Chrysomya putoria (Wiedemann). In South America, C. rufifacies (Macquart) has only been reported from Argentina and Colombia. This study records C. rufifacies from Brazil for the first time. The specimens were collected in an area of cerrado (savanna-like vegetation) in the municipality of Caxias in state of Maranhão, and were attracted by pig carcasses.

Fruits and frugivores of the Brazilian Cerrado: ecological and phylogenetic considerations Acta Botanica
Kuhlmann,Marcelo; Ribeiro,José Felipe.
ABSTRACT Knowing the morphological and phylogenetic patterns of fruits of a plant community may elucidate plant-frugivore interactions, and analysis of dispersal syndromes is a practical approach to understanding these mutualisms. We investigated different zoochorous fruits and frugivorous animals among Cerrado formations (forest, savanna and grassland), mapped dispersal syndromes on a Cerrado angiosperm phylogeny and tested for phylogenetic signal. For a core region in Cerrado, we found that, among almost a thousand fruit species and 258 fruit-eating vertebrates, 60% of the fruits had an ornithochorous syndrome and that 70% of the frugivores were birds. Most fruit and frugivorous species (~80%) inhabit forest formations, but many of them also occurred in...

Habitat use and movements of Glossophaga soricina and Lonchophylla dekeyseri (Chiroptera: Phyllostomidae) in a Neotropical savannah Rev. Bras. Zool.
Aguiar,Ludmilla M.S.; Bernard,Enrico; Machado,Ricardo B..
The greatest current threat to terrestrial fauna is continuous and severe landscape modification that destroys and degrades animal habitats. This rapid and severe modification has threatened species, local biological communities, and the ecological services that they provide, such as seed dispersal, insect predation, and pollination. Bats are important pollinators of the Cerrado (woodland savanna) because of their role in the life cycles of many plant species. However, there is little information about how these bat species are being affected by habitat loss and fragmentation. We used radio-tracking to estimate the home ranges of Glossophaga soricina (Pallas, 1776) and Lonchophylla dekeyseri Taddei, Vizotto &amp; Sazima, 1983. The home range of G....

Salt concentrations in culture media for the development of Dipteryx alata in vitro PAB
Araruna,Elequisandra da Costa; Ribeiro-Oliveira,João Paulo; Pereira,Vanderley José; Asmar,Simone Abreu; Melo,Berildo de.
Abstract: The objective of this work was to evaluate how salt concentrations in media used for in vitro cultures affect the early development of “barueiro” (Dipteryx alata) seedlings obtained from the shoot apex. Two different in vitro culture media - Murashige & Skoog (MS) and wood plant medium (WPM) - in different salt concentrations (25, 50, 75, and 100%) were used. At 120 days, the D. alata seedlings in the MS medium, in its original concentration (100%), developed better than in other concentrations or in the WPM. Therefore, the MS medium was considered the most suitable for ensuring in vitro establishment because it provided greater root length (27.65 cm) and number of leaves per plant (26 leaves) than the other medium.

Study area characterization and preliminary results on GHG emissions in eucalyptus forest, Mato Grosso do Sul. Repositório Alice
MAURO, R.; PEREIRA, M.; AGIOVA, A.; ARAUJO, A..
Abstract: Forestry in the Cerrado Biome have the potential to act as carbon sink and storage and can be used as climate change mitigation option through compensatory planting. The Cerrado occupies about 23% of the national territory, presenting varied physiognomies. The Cerrado sensu stricto (herbaceous layer with different densities of tree and shrubs) is the predominant physiognomic type with total extent of about 41.8 million hectares. The Cerrado biome may play a significant role on global carbon balance due to carbon storage and fixation. However, vast areas of Cerrado have been degraded as a result of extensive and frequent fire mainly related with cattle ranching. Planted forests in Cerrado are predominant comprised of eucalyptus, which are...

Taxonomic key for the genera of Elmidae (Coleoptera, Byrrhoidea) occurring in Goiás State, Brazil, including new records and distributional notes Rev. Bras. entomol.
Barbosa,Felipe F.; Fernandes,André S.; Oliveira,Leandro G..
A taxonomic key for the genera of Elmidae (Coleoptera, Byrrhoidea) occurring in Goiás State, Brazil, including new records and distributional notes. Despite their great diversity and high abundance in Neotropical aquatic environments, the fauna of Elmidae remains practically unknown in some areas and even entire biomes in this region. In this work we bring, for the first time, faunistic data for the Elmidae of central Brazil. The aim of this work was to inventory the Elmidae fauna in central, southwestern and southeastern Goiás State, Brazil and to produce a taxonomic key, at genus level, for adults from the studied region. The taxonomic key presented herein offers means for the identification of all the 13 genera known to occur in Goiás, 11 of them being...

The influence of fire on the assemblage structure of foraging birds in grasslands of the Serra da Canastra National Park, Brazil Anais da ABC (AABC)
Reis,Matheus G.; Fieker,Carolline Z.; Dias,Manoel M..
Grasslands are the most threatened physiognomies of the Cerrado biome (Brazilian savanna), a biodiversity hotspot with conservation as a priority. The Serra da Canastra National Park protects the most important remnants of the Cerrado's southern grasslands, which are under strong anthropogenic pressure. The present study describes the structure of bird assemblages that directly use food resources in burned areas, comparing areas affected by natural fire to the areas where controlled fires were set (a management strategy to combat arson). The tested null hypothesis was that different bird assemblages are structured in a similar manner, regardless of the post-fire period or assessed area. Between December/2012 and January/2015, 92 species were recorded...

Santos,Tassiana Reis Rodrigues dos; Pinto,José Roberto Rodrigues; Lenza,Eddie; Mews,Henrique Augusto.
We describe the floristic composition of the tree-shrub vegetation in 10 areas of rocky outcrop cerrado in Goiás State, Brazil. Ten 20×50m plots (totaling 1ha) were established and all of the individuals with diameters at 30cm above soil level (DB30) ³5cm were included in the sampling. Comparative analyses of the flora were realized using similarity indices (Sørensen and Czekanowski), classification analysis (TWINSPAN), and the Mantel test. A total of 13,041 tree-shrub individuals were sampled, distributed among 219 species, 129 genera and 55 families. Fabaceae was the most well-represented family, followed by Myrtaceae, Melastomataceae, Vochysiaceae, Malphigiaceae, and Rubiaceae. Fully 42.3% of the comparisons evaluated by the Sørensen index were...
