1. Leaf structural traits of three species of Qualea Mart. (Vochysiaceae) in a cerradão area in the Cerrado-Amazonian Forest transition
Resumo Qualea é um gênero comumente encontrado em diferentes fisionomias do cerrado brasileiro, crescendo em ecossistemas abertos até áreas florestais fechadas, sujeitos à alta irradiância, incêndios, baixa disponibilidade de nutrientes e deficit hídrico sazonal. Comparam-se aqui, atributos estruturais foliares de Qualea grandiflora Mart., Qualea mul

2. Body mass index and glucose variations during the night in free-ranging Artibeus planirostris (Chiroptera: Phyllostomidae)
ABSTRACT Body condition is an important measure to estimate the energy reserve of an organism. Scientists frequently use body condition indices (BCIs) with morphometric measures but direct measurements, such as blood glucose, seem to be more reliable. We observed oscillations in the body condition and glucose indexes of individuals of Artibeus planirostris (

3. Mineralogy of the Clay Fraction and Chemical Properties of Soils Developed from Sedimentary Lithologies of Pirambóia, Sanga-the-Cabral and Guará Geological Formations in Southern Brazil
ABSTRACT Quali-quantitative and crystallographic characterizations of the different minerals of a soil are essential for the best evaluation of its genesis, degree of weathering, active pedogenetic processes, physical and chemical properties, and its potential reserve of mineral nutrients. This study presents the results of mineralogical investigations carri

4. The necessity of management in a lake of the Atlantic Forest biodiversity hotspot: nitrogen levels connected to a persistent bloom of Cylindrospermopsis raciborskii
ABSTRACT Conservational studies of the threatened Atlantic Forest biome are frequently restricted to terrestrial ecosystems. We know little about the water bodies, specially considering that this biome covers the third largest system of lakes in Brazil. Some of these lakes are located inside the protected "Rio Doce State Park", but many others are found outs

5. Biomass estimation of Triplectides egleri Sattler (Trichoptera, Leptoceridae) in a stream at Ducke Reserve, Central Amazonia
ABSTRACT Biomass is a fundamental measure for understanding the structure and functioning (e.g. fluxes of energy and nutrients in the food chain) of aquatic ecosystems. We aim to provide predictive models to estimate the biomass of Triplectides egleri Sattler, 1963, in a stream in Central Amazonia, based on body and case dimensions. We used body length, head

6. Updated List and identification key of 219 tree species of white sand forests of the Allpahuayo Mishana National Reserve, Loreto, Peru
White sand forests, although low in nutrients, are characterized not only by several endemic species of plants but also by several monodominant species. In general, plants in this forest have noticeably thin stems. The aim of this work was to elaborate a parallel dichotomous key for the identification of Angiosperm tree species occurring on white sand forest

7. Produção e composição química da serapilheira em um gradiente topográfico em mata de galeria no bioma cerrado.
RESUMO: Em função do gradiente de umidade na topografia do terreno e de diferenças entre estações seca e chuvosa, o presente trabalho teve como objetivos quantificar a produção anual e a disponibilidade de nutrientes (N, P, K, Ca, Mg E S) na serapilheira e estimar a eficiência do uso de nutrientes em uma Mata de Galeria. O experimento foi estabelecid

8. Qualidade da água e distribuição espacial de foraminíferos bentônicos em estuários das Baías Norte e Sul da Ilha de Santa Catarina (Brasil)
Watersheds with different characteristics lead to different rates of biogeochemical elements that contribute in estuarine systems. Thus, this study investigated the contribution of drainage on the nutrients as well as the responses of benthic foraminifera, with focus on estuarine region of six major systems that discharge in the North and South bays of Santa

9. Gênese, classificação e mapeamento de solos desenvolvidos de rochas pelíticas em áreas cultivadas com eucalipto em Minas Gerais / Genesis, classification and mapping of soils developed from pellitic rocks in areas cultivated with eucalyptus in Minas Gerais
Because the demand for arable areas has turned very intense in the last years, soils then considered as not appropriate to agricultural use are now being revalued and studied in order to use them for forest plantings, to example of Cambisols developed from pellitic rocks of Bambui Group. In reason of the expressiveness of these soils, usually associated Lato

10. Avaliação sócio-ambiental do uso de efluente de esgoto tratado na irrigação de culturas no Município de Lins - SP / Socioenvironmental assessment of the use of treated sewage effluent in the irrigation of crops in Lins - SP
Worldwide, there is an increasing competition for the use of water between different sectors of society. The agriculture is a major consumer of the total fresh water available. In this context, it is desirable a reallocation of water resources used in agriculture to other sectors, such as public supply. Since done in a controlled way, irrigation with effluen

11. Eficiência do uso de nutrientes ao longo de uma transição de mata de galeria e cerrado no Distrito Federal
In the cerrado landscape, gallery forests occur along the streams and are surrounded by open forms of cerrado vegetation, accompanied by edaphic gradients. Transitions between forest physiognomies and adjacent open cerrado forms involve not only changes in the structure, dynamics, floristic composition of vegetation and species distribution, but also variati

12. Estudo da comunidade fitoplanctônica como bioindicador de poluição em três reservatórios em série do Parque Estadual das Fontes do Ipiranga (PEFI), São Paulo, SP / Phytoplankton communitys study as bioindicator of pollution in three cascading reservoir system in Parque Estadual das Fontes do Ipiranga (PEFI), São Paulo, SP
The three shallow cascading reservoir system are located in Parque Estadual das Fontes do Ipiranga (PEFI) Biological Reserve in the southern of São Paulo city where located headwater Ipiranga Stream. The first reservoir is linked to Lago das Garças, a shallow and eutrophic environment, where have become frequent blooms of Cyanobacteria that produce aggress
