Aim: To establish the dynamics of <i>C. furcoides</i> in horizontal and temporal scales; and to determine the main ecological factors related to its dynamics. Methods: Samples were taken in five stations between July 2002 and July 2003. Physical and chemical variables were sampled monthly. Density was evaluated by sampling carried out within the photic zone. Growth rate (r), Turnover rate (T), Generation Time (gt), Niche Width (NW), Taylor's Power Law, and the rate of population change (σ<SUB>s</SUB>), were used. Canonical Correspondence Analysis (CCA) was used too. Results: Total density was 264163.4 cel.L<SUP>-1</SUP>, the highest was found in Up Río Chico and the lowest in Dam. The species was more clustered in space than in time. r ranged between 0.29 and 0.3 cel.d<SUP>-1</SUP>, gt between 1.8 and 2.4 days, T between 0.55 and 0.42 divisions per day, NW between 0.58 and 0.72, and σ<SUB>s</SUB> between 0.3 d<SUP>-1</SUP> and 2.3 d<SUP>-1</SUP>. The first three components of CCA explained 92.2% of the variation. Density was positively associated with chlorophyll a, NH<SUB>4</SUB>+, RWCS and wind direction. Light attenuation, NO<SUB>3</SUB>-, SiO<SUB>2</SUB> and O<SUB>2</SUB> were negatively associated with <i>C. furcoides</i>. Discussion: <i>C. furcoides</i> is a S strategist; it increases its density in the warmest periods under eutrophic conditions, low light penetration and high thermal stability; it is independent of the temperature but dependent of changes in rainfall and nutrients, - especially nitrogen - and not soluble phosphorus. Up Río Chico presented the best conditions for the increase of <i>C. furcoides</i>, since this station presented the highest levels of total nitrogen, and the highest relative stability. Conclusion: <i>C. furcoides</i> has a very similar ecology to that of <i>C. hirundinella</i>. It is an organism highly variable in temporal and spatial scales, with a wide niche and a clustered distribution. It belongs to the Morpho-funtional Group V and to L<SUB>o</SUB> and L<SUB>M</SUB> Assotiations. |

Métodos: As amostras foram coletadas em cinco estações entre julho de 2002 e julho de 2003. As variáveis físicas e químicas foram amostrados mensalmente e a densidade foi estimada a través de coletas realizadas dentro da zona fótica, a taxa de crescimento (r), taxa de rotatividade (T), Tempo de Geração (GT), Largura do nicho (NW), Power Taylor’s Law, e a taxa de mudança da população (σ<SUB>s</SUB>) foram utilizados. Análise de Correspondência Canônica (CCA) foi usado também. Resultados: A densidade total foi 264.163,4 cel.L<SUP>-1</SUP>, a maior foi encontrada em Up Río Chico e a mais baixa na barragem. As espécie foi achada mais agrupada no espaço que no tempo. O valor de r variou entre 0,29 e 0,3 cel.d<SUP>-1</SUP>, GT entre 1,8 e 2,4 dias, T entre 0,55 e 0,42 divisões por dia, NW entre 0,58 e 0,72, e σ<SUB>s</SUB> entre 0,3 e 2,3 d<SUP>-1</SUP>. Os três primeiros componentes da CCA explicaram 92,2% da variação. A densidade foi positivamente associado com clorofila a, NH<SUB>4</SUB>+, RWCS e direção do vento. A atenuação da luz, N<SUB>3</SUB>-, SiO<SUB>2</SUB> e O<SUB>2</SUB> estiveram associados negativamente com <i>C. furcoides</i>. Discussão: <i>C. furcoides</i> é um estrategista tipo S, aumenta sua densidade nos periodos mais quentes perante condições eutróficas, penetração de luz baixa e alta estabilidade térmica. A espécie é independente da temperatura, mas dependente das mudanças na precipitação e nutrientes, – especialmente nitrogênio – não fósforo solúvel. Up Río Chico apresentou as melhores condições para o aumento de <i>C. furcoides</i>, porque esta estação apresentou os mais altos níveis de nitrogênio total e a maior estabilidade relativa. Conclusão: <i>C. furcoides</i> tem uma ecologia muito semelhante a aquela de <i>C. hirundinella</i>; é um organismo altamente variável nas escalas temporal e espacial, com uma vasta gama de nicho e uma distribuição agregada. Pertence ao Grupo morfo-funcional V e às associações Lo e LM.Facultad de Ciencias Naturales y Museo2012info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArticulohttp://purl.org/coar/resource_type/c_6501info:ar-repo/semantics/articuloapplication/pdf207-219http://sedici.unlp.edu.ar/handle/10915/84011enginfo:eu-repo/semantics/altIdentifier/issn/0102-6712info:eu-repo/semantics/altIdentifier/doi/10.1590/S2179-975X2012005000039info:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-sa/4.0/Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)reponame:SEDICI (UNLP)instname:Universidad Nacional de La Platainstacron:UNLP2024-05-08T12:54:01Zoai:sedici.unlp.edu.ar:10915/84011Institucionalhttp://sedici.unlp.edu.ar/Universidad públicaNo correspondehttp://sedici.unlp.edu.ar/oai/snrdalira@sedici.unlp.edu.arArgentinaNo correspondeNo correspondeNo correspondeopendoar:13292024-05-08 12:54:02.012SEDICI (UNLP) - Universidad Nacional de La Platafalse |
