25. Nest architecture development of grass-cutting ants
ABSTRACT Atta bisphaerica is a species of grass-cutting ants commonly found in the Cerrado biome. The Brazilian Cerrado (savanna) biome covers 2 million km representing 23% of the area of the country. It is an ancient biome with rich biodiversity, estimated at 160,000 species of plants, fungi and animals. However, little is known about their nest architectur

26. Phylogeographic analyses of the pampas cat (Leopardus colocola; Carnivora, Felidae) reveal a complex demographic history
Abstract The pampas cat is a small felid that occurs in open habitats throughout much of South America. Previous studies have revealed intriguing patterns of morphological differentiation and genetic structure among its populations, as well as molecular evidence for hybridization with the closely related L. tigrinus. Here we report phylogeographic analyses e

27. BRS 368RF: A glyphosate tolerant, midseason upland cotton cultivar for Northeast and North Brazilian cerrado
Abstract Cotton cultivar BRS 368RF was developed by EMBRAPA in a partnership with the Bahia Foundation, aiming to create high-yielding germplasm by adding transgenic traits addressed to Brazilian Savanna (cerrado) of the Northeast and North regions. BRS 368RF is a midseason cultivar and has yield stability and transgenic tolerance to glyphosate.

28. Interseasonal variation of Chrysodeixis includens (Walker, [1858]) (Lepidoptera: Noctuidae) populations in the Brazilian Savanna
Abstract Chrysodeixis includens (Walker, [1858]) is currently the main plusiine pest in the Americas, not only because of the damage caused to soybean, but also with several crop species in a broad geographical range. However, its population dynamics is still poorly understood, despite outbreak records that are common across different locations in the Americ

29. Fungal Community Structure as an Indicator of Soil Agricultural Management Effects in the Cerrado
ABSTRACT Forest-to-agriculture conversion and soil management practices for soybean cropping are frequently performed in the Cerrado (Brazilian tropical savanna). However, the effects of these practices on the soil microbial communities are still unknown. We evaluated and compared the fungal community structure in soil from soybean cropland with soil under n

30. Morphological, mechanical and chemical aspects of processing tomatoes produced in Brazilian savanna
Abstract The aim of this study was to determine the physical and chemical characteristics of ten processing tomatoes cultivars (H9992, H9553, U2006, N901, E8755, BA5445, F170, HMX, AP533 and CVR) produced in the city of Morrinhos, Goiás State, Brazil, in order to assess the fruit quality and contribute with more subsidies for choosing tomato cultivars for p

31. Leaf anatomical traits of non-arboreal savanna species along a gradient of tree encroachment
ABSTRACT In the Brazilian savanna (Cerrado of Brazil), fire suppression has transformed typical savanna formations (TS) into forested savanna (FS) due to the phenomenon of encroachment. Under encroachment, non-arboreal plants begin to receive less light due to greater tree density and canopy closure. Here we aim to evaluate if leaf anatomical traits of non-a

32. The role of gallery forests in maintaining Phlebotominae populations: potential Leishmania spp. vectors in the Brazilian savanna
BACKGROUND Knowledge on synanthropic phlebotomines and their natural infection by Leishmania is necessary for the identification of potential areas for leishmaniasis occurrence. OBJECTIVE To analyse the occurrence of Phlebotominae in gallery forests and household units (HUs) in the city of Palmas and to determine the rate of natural infection by trypanos

33. Phylogenetic community structure reveals differences in plant community assembly of an oligotrophic white-sand ecosystem from the Brazilian Atlantic Forest
ABSTRACT Mussununga, an oligotrophic sandy savanna ecosystem, comprises distinct physiognomies along fire, water and nutrient availability gradients. Grasslands and woodlands are constrained at the opposite poles of these gradients, with grasslands occurring in areas with poorer soils and higher levels of both water-stress and fire intensity. According to th

34. New species of Lopesia Rübsaamen (Diptera: Cecidomyiidae) associated with Andira humilis Mart. ex Benth. (Fabaceae)
Abstract A new species of Lopesia Rübsaamen, 1908 induces leaf galls on Andira humilis (Fabaceae) in the Cerrado biome (Brazilian savanna) of Bahia, Mato Grosso and São Paulo states, Brazil. Larva, pupa, female, and male of this new species of gall midge are described and illustrated in this paper.

Resumo A ocorrência de brotos estipulares em Marattiaceae tem sido observada por diferentes autores, geralmente sob condições de cultivo. Neste estudo, é descrito o desenvolvimento de brotos estipulares em uma população de Danaea nodosa localizada em uma Mata de Galeria no Cerrado brasileiro. De junho de 2006 a julho de 2007, 40 indivíduos foram monit

36. Leaf morphology and venation of Psidium species from the Brazilian Savanna
ABSTRACT The Brazilian Savanna biome has the largest plant diversity among savannas worldwide and is the predominant biome in Goiás state, Brazil. Among plant species previously catalogued in the Brazilian Savanna, the Myrtaceae family has received attention, as these plants show great economic potential for its medicinal properties, food and ecological imp
