Resumen

DE LOS RIOS-ESCALANTE, Patricio; SOBENES, Catterina  y  PARRA, Luciano. USE OF NULL MODELS FOR COMPARE THE ZOOPLANKTONIC STRUCTURE IN THREE LAKES OF AYSEN REGION, CHILE. Anales Instituto Patagonia (Chile) [online]. 2013, vol.41, n.1, pp.71-75. ISSN 0718-686X.  http://dx.doi.org/10.4067/S0718-686X2013000100006.

The zooplanktonic communities in Chilean inland waters are characterized by the high calanoid copepods dominante and low species number that is due to the oligotrophy and wide conductivity gradient. A view point in ecology is the null models use for determine that the community has not structural factors. The aim of the present study is analyze the zooplanktonic structure in three lakes of Aysen region with null models based in size overlap, with the aim of support or reject the traditional ecological results that described the presence of regulator factors in community structure. The results of size overlap revealed that the size structure is random, that is due to the absence of food resources limitation, interespecific competency absence and colonization and extinction population process.

Palabras clave : zooplankton; communities; null models; Patagonia.
