1. Drivers of floristic variation in biogeographic transitions: insights from the ecotone between the largest biogeographic domains of South America
ABSTRACT Ecological transitions usually represent vulnerable ecosystems and high biodiversity. Investigating their drivers is important from both biogeographic and conservationist perspectives. One of these transitions is situated between the two largest biogeographic domains of South America - the Amazon and the Cerrado. We evaluated variation in tree flori

2. Food resource partitioning among species of Astyanax (Characiformes: Characidae) in the Lower Iguaçu River and tributaries, Brazil
RESUMO O particionamento de recursos permite a coexistência interespecífica e é frequentemente relatado para espécies semelhantes. Predizemos a existência de partição de recursos entre espécies de Astyanax que co-ocorrem no baixo rio Iguaçu. O total de 848 estômagos de cinco espécies de Astyanax foi analisado. Algas, plantas terrestres e frutos/se

3. A snapshot of the limnological features in tropical floodplain lakes: the relative influence of climate and land use
Resumo Objetivo O objetivo desse estudo foi investigar a influência relativa do clima (temperatura e precipitação) e do uso da terra nas características limnológicas de 30 lagoas da planície de inundação do Rio Araguaia, no Brasil Central, um importante rio que drena no Cerrado brasileiro. Métodos As lagoas foram amostradas em um mesmo período,

4. Partitioning of rainfall into throughfall, stemflow, and interception loss in the Brazilian Northeastern Atlantic Forest
RESUMO A compreensão do comportamento hidrológico e da distribuição da vegetação em um ambiente semiárido é fundamental para o desenvolvimento de técnicas e estratégias para a convivência com as secas. Objetivou-se com esse trabalho, quantificar o particionamento da precipitação pela vegetação caracterizada como Mata Atlântica Nordestina bem

5. Randomized clinical trial of the effect of NovaMin and CPP-ACPF in combination with dental bleaching
Abstract Objective This randomized, controlled, double-blind clinical study evaluated the effect of calcium sodium phosphosilicate (NovaMin) and casein phosphopeptide-amorphous calcium phosphate with fluoride (CPP-ACPF) on the prevention of post-operative sensitivity and on the effects of clinical bleaching treatment. Material and Methods Sixty volunteer

6. Distinct population structure for co-occurring Anopheles goeldii and Anopheles triannulatus in Amazonian Brazil
To evaluate whether environmental heterogeneity contributes to the genetic heterogeneity in Anopheles triannulatus, larval habitat characteristics across the Brazilian states of Roraima and Pará and genetic sequences were examined. A comparison with Anopheles goeldii was utilised to determine whether high genetic diversity was unique to An. triannulatus. St

7. Variabilidade e divergência genética em cruzamentos dialélicos de soja / Variability and genetic divergence in soybean diallel crosses
Estimates of genetic divergence (DG) have not been used for parental selection in breeding programs, because of the inconsistence of the results. The objective of this study was to evaluate the possibility of predicting the genetic variability (VG) of soybean populations derived from two-way crosses, using DG data from AFLP markers (Bonato et al., 2006), and

8. Genotype and environment interaction on soybean yield in Mato Grosso State, Brazil.
The objective of this work was to investigate the genotype-environment interaction in Mato Grosso State, MT. The relative importance of locations, years, sowing dates and cultivars and their interactions was analyzed from data collected in regional yield trials performed in a randomized complete block design with four replications, from 1994-1995 through 199

10. Indicadores microbiológicos de qualidade do solo em Florestas de Araucária no Estado de São Paulo / Microbilogical indicators of soil quality in Araucaria Forest in São Paulo State
A Araucaria angustifolia, conhecida como Pinheiro-do-Paraná é uma espécie ameaçada de extinção no Brasil, está inserida num bioma rico em biodiversidade, a Mata Atlântica, e muito pouco se conhece sobre os atributos microbiológicos dessas florestas. Este trabalho teve como objetivo avaliar potenciais atributos microbiológicos do solo e algumas vari

11. Estimation procedures affect the center of pressure frequency analysis
Even though frequency analysis of body sway is widely applied in clinical studies, the lack of standardized procedures concerning power spectrum estimation may provide unreliable descriptors. Stabilometric tests were applied to 35 subjects (20-51 years, 54-95 kg, 1.6-1.9 m) and the power spectral density function was estimated for the anterior-posterior cent

12. Viability of reciprocal recurrent selection in populations derived from single-cross maize hybrids / Viabilidade da seleÃÃo recorrente recÃproca em populaÃÃes derivadas de hÃbrido simples de milho
In a recurrent selection program it is primordial to know whether genetic progress has been reached and the existence of genetic variability for future selection cycles. Thus, this work was carried out to evaluate the genetic progress up to C2, on a first stage, and to estimate genetic variance and covariance components, responses to selection and heterosis
