Caracterização florística e estrutural das florestas naturalmente fragmentadas no Parque Estadual do Guartelá, município de Tibagi, estado do Paraná
(Sociedade Botânica do Brasil, 2012-03-01)
A Floresta Ombrófila Mista na região dos Campos Gerais do Paraná é naturalmente fragmentada, ocorrendo em forma de capões ou ao longo dos cursos d'água. Com o objetivo de caracterizar a composição e estrutura destes ...
Correlação entre uso da terra e qualidade da água subterrânea
(Associação Brasileira de Engenharia Sanitária e Ambiental - ABES, 2014-04-01)
Este trabalho descreve a correlação entre parâmetros de uso da terra (área agricultada, área edificada, pastagem, solo exposto e vegetação intermediária) e de qualidade da água subterrânea (pH, sólidos totais dissolvidos ...
Tensor decompositions for signal processing applications: from two-way to multiway component analysis
(Institute of Electrical and Electronics Engineers, 2015-03)
The widespread use of multi-sensor technology and the emergence of big datasets has highlighted the limitations of standard flat-view matrix models and the necessity to move towards more versatile multi-way data analysis ...
Leaf spectra and weight of species in canopy, sub-canopy, and understory layers in a Venezuelan Andean cloud forest

Characterizing chaotic melodies in automatic music composition
(AMER INST PHYSICS, 2010)
In this paper, we initially present an algorithm for automatic composition of melodies using chaotic dynamical systems. Afterward, we characterize chaotic music in a comprehensive way as comprising three perspectives: ...
Geographical variation in head shape of a Neotropical group of toads: the role of physical environment and relatedness
In this study we review the morphological variation within the Rhinella crucifer species group using geometric morphometrics. We sampled 270 specimens from 78 localities comprising all genetic units delimited for the group. ...
Growth and reproductive dynamics of the South American red shrimp, Pleoticus muelleri (Crustacea: Solenoceridae), from the southeastern coast of Brazil
(Elsevier B.V., 2012-12-01)
The increase in the fishing fleet in southeastern Brazil and the decrease in the landings of profitable shrimp species have contributed to the incorporation of additional species into those fisheries, such as Pleoticus ...
The relationship between environmental variation and species abundance in shrimp community (Crustacea : Decapoda : Penaeoidea) in south-eastern Brazil
(Cambridge University Press, 2008-02-01)
The impact of shrimp fisheries in tropical regions has become comparable to the world's most intensively exploited temperate shed ecosystems. The increase in the fishing fleet in south-eastern Brazil and the decrease in ...
Analyzing the connectivity between regions of interest: An approach based on cluster Granger causality for NRI data analysis
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
The identification, modeling, and analysis of interactions between nodes of neural systems in the human brain have become the aim of interest of many studies in neuroscience. The complex neural network structure and its ...
Correlated Morphological and Genetic Patterns in Embothrium coccineum (Proteaceae) Across Climate and Geography: Can Embothrium Survive Patagonian Climate Change?
(Csiro Publishing, 2013-12)
Adaptive radiation and reproductive isolation can determine the biogeographic structure of any species. We examine patterns of biotic variation in Embothrium coccineum, a Proteaceae tree that spans 20º of latitude and is ...
