Resumo: The temporal dynamics of E. pulvinata and its relation to abiotic variables were evaluated monthly during January to December 2007 in a stream located in the central-southern part of Parana State (25º11’16”S - 51º21’25”W). The abundance of the population in terms of percentage cover was obtained by means of the quadrat technique and the following stream water variables were measured: current velocity, irradiance, depth, substrate type, temperature, oxygen saturation, conductivity, pH and turbidity. The abundance of E. pulvinata was considered high (X = 26.7%), with more development (22-46%) during autumn/winter. The low values (0-0.08) of niche width and the few associations with environmental variables shows that the population evaluated is a generalist with regards to the environment in which it occurs. Factors most strictly related were the water flow and the particle size of the substrate, which positively correlated to the seasonal pattern of the population investigated.

A abundância da população em termos de cobertura percentual foi obtida através da técnica de quadrados e as seguintes variáveis físicas e químicas da água do riacho foram mensuradas: velocidade da correnteza, irradiância, profundidade, tipo do substrato, temperatura, saturação de oxigênio, condutividade, pH e turbidez. A abundância de E. pulvinata foi considerada alta (X = 26,7%), com maiores valores (22-46%) no período correspondente ao outono/inverno. Os baixos valores de largura de nicho (0-0,08) e as poucas correlações com as variáveis ambientais mostram que a população é bastante generalista com relação ao ambiente em que ocorre. Fatores mais estreitamente relacionados com a abundância foram o fluxo da correnteza e o tamanho de partículas do substrato, os quais influenciaram diretamente no padrão sazonal da população investigada, sendo as condições mais favoráveis o menor fluxo (menor profundidade) e substratos estáveis (rocha e matacão).Iheringia.
