Comunidades Zooplanctónicas en Lagos Del Parque Nacional Torres Del Paine: Un Nuevo Enfoque De Análisis De Factores Reguladores De Su Estructura Comunitaria

Abstract: Torres del Paine se caracteriza por la presencia de una serie de ecosistemas lacustres tales como grandes lagos ultraoligotróficos, lagos pequeños con peces, y lagunas pequeñas superficiales. Los estudios publicados sobre la base de información obtenida entre los años 1989 y 1991, indican que a la riqueza de especies está indirectamente relacionada con la conductividad y directamente relacionada con la concentración de clorofila. El presente trabajo consistió en un análisis de información de algunos lagos del … Show more

“…The co-occurrence analysis revealed for all studied periods (sampling dates) and for all simulations, that the observed plankton associations were random and no regulating factor was recognizable (table II). Our results are similar to those described for the zooplankton communities of shallow lakes in southern Patagonia and the mountain lakes in northern Patagonia , 2010De los Ríos & Soto, 2009;De los Ríos & Roa, 2010). This is interesting, because our results were obtained in a very different type of lake (large, deep, oligotrophic, soft water), which is dominated by a different zooplankton species (in the example: B. gracilipes) and also large, mixotrophic ciliates (Woelfl, 2007).…”

“…The results described above agree with results obtained for other lakes of glacial origin, for example lakes Sarmiento and Del Toro in Torres del Paine National Park [9], and General Carrera Lake [7], where the markedly abundant calanoid species B. gracilipes Daday, 1901 and/or B. michaelseni are associated with low abundance of cyclopoid copepods and cladoceran N. chilensis. Similar results were observed for other glacial oligotrophic lakes in the park, such as Nordsdenkjold and Grey, where the zooplankton communities consist of only two species (B. michaelseni and Tropocyclops prasinus (Fischer, 1860) [10].…”
