Resumo: | The present research aimed to quantify the vascular plants caloric content in two reservoirs in Paraná, as well as the spatial and ecological group variabilities. The sampling was done in December 2002, in the fluvial, transition and lacustrine zones in Rosana and Mourão reservoirs. Aquatic macrophytes and riparian vegetation mature leaves, from different individuals (n=5), belonging to the same species, were randomly sampled. In order to obtain the caloric content, in cal.g-1 dry weight, the samples were pulverized in a ball mill and subjected to combustion in a PARR calorimetric bomb. The data were treated with a null model ANOVA (EcoSim 7.44 program). A wide caloric variability was verified in the vascular plants analysed. Besides, the spatial and ecological group variabilities were significant, so it is not recommended, being use of only one caloric value to these primary producers in energy flow models, necessary a preliminary inspection of the breadth and of the factors that determine such variation |

Foram amostradas, ao acaso, folhas maduras de plantas aquáticas e da vegetação ripária de diferentes indivíduos (n = 5), pertencentes à mesma espécie. Para obtenção do conteúdo calórico, em cal.g-1 de peso seco, as amostras foram maceradas em moinho de bola e submetidas à combustão em bomba calorimétrica PARR. Os dados foram submetidos a uma ANOVA modelo nulo, utilizando-se o programa EcoSim versão 7.44. Foi constatado que as plantas vasculares analisadas apresentaram ampla variabilidade calórica. Além disso, foram significativas as variabilidades espacial e entre os grupos ecológicos, não sendo recomendável o uso de um único valor calórico para estes produtores primários em modelos de fluxo de energia, sendo necessária, uma inspeção preliminar da amplitude e dos fatores que são determinantes de tal variaçãoUniversidade Estadual De Maringá2008-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/161110.4025/actascibiolsci.v26i2.1611Acta Scientiarum.
