Resumo: | In order to define the effect of seston size fraction as a food source for Ceriodaphnia cornuta and Diaphanosoma spinolosumin, situ experiments using natural abundance of delta;13C and δ15N were carried out during the rising water period in Catalão Lake. Both species were fed with three different fractions of seston from the lake (< 10, < 30 and < 60 µm) and maintained in submerged 1.1 L plastic bottles for nine days. Ten individuals were put in each flask, maintaining three flasks for each fraction, for a total of 27 flasks per species. Every three days we collected three flasks and fixed the individuals for subsequent counting and observation of demographic population parameters. The organisms in the last three flasks of each fraction were fixed for stable isotope analysis of delta;13C and δ15N. Both species grew in all of the food fractions, with the best the performance coming in the < 30 µm fraction. D. spinolosum and C. cornuta showed enrichment in delta;13C and δ15N, which was highest in the < 10 µm fraction for both species. These results show that the seston size fractions tested produce different population growth rates and isotopic signatures in cladocerans. |

As duas espécies tiveram acesso a três diferentes frações de seston (< 10, < 30 e < 60 µm) sendo mantidas em garrafas plásticas de 1,1 L submersas, durante nove dias. As atividades foram iniciadas com uma população de dez indivíduos em cada frasco, com três frascos por cada fração e quatro intervalos de tempo, para um total de 27 frascos por espécie. A cada três dias, foram coletados três frascos e os organismos foram fixados para contagem e observação de parâmetros populacionais. Os organismos nos últimos três frascos de cada fração foram fixados com formalina e usados para análise de isótopos estáveis de carbono e nitrogênio. As duas espécies cresceram em todas as frações de alimento, sendo melhor seu desempenho populacional na fração < 30 µm. D. spinolosum e C. cornuta apresentaram enriquecimento nos valores de delta;13C e δ15N, sendo maior na fração < 10 µm. Estes resultados sugerem que as frações do seston testadas produzem diferentes taxas de crescimento populacional e assinaturas isotópicas nos cladóceros.Universidade Estadual De Maringá2011-02-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersioncrescimento etárioapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/726010.4025/actascibiolsci.v33i1.7260Acta Scientiarum.
