“…That study identifi ed a generalized track in southern Patagonia, the Atlantic coast of Argentina, the Andean mountains of northern Argentina and Chile, and the Andean regions of Bolivia, Colombia and Ecuador. Nevertheless, the nodes reported in the present study differ from those identifi ed by Menu-Marque et al (2000). Species of Hyalella are also known from Mexico and Central America, Bousfi eld (1996) supported it, and suggested the presence of Austrohyalella and Mesohyalella genus in South America.…”

“…The generalized tracks identifi ed are similar to those described by Menu-Marque et al (2000), who applied this procedure to the copepod genus Boeckella. That study identifi ed a generalized track in southern Patagonia, the Atlantic coast of Argentina, the Andean mountains of northern Argentina and Chile, and the Andean regions of Bolivia, Colombia and Ecuador.…”

“…Graph of associations between species number, calanoid, cladoceran and cyclopoid percentage with chlorophyll concentration for studied sites. gracilis in all studied sites is a new report, because, since only rarely it has been reported for Chilean lakes (MENU-MARQUE et al 2000). Nevertheless, in recent studies, this species was reported from high mountain lakes in northern Patagonia (TROCHINE et al 2006, DE LOS RIOS et al 2007.…”

Even though the Chilean lakes are characterized by their oligotrophy, a transition from oligotrophy to mesotrophy, due human intervention, has been reported in some lakes. Nevertheless, there are still some pristine and unpolluted small lakes and ponds in mountain zones, free of human intervention and surrounded by native forests. Nine unpolluted, oligotrophic and pristine water bodies located in Cañi Park, a mountain zone with altitudes between 1000 to 1500 m a.s.l and forests where Nothofagus dombeyi, N. pumilio and Araucaria araucana predominate, were studied. For each sampled lake, zooplankton was collected and environmental parameters were obtained (conductivity, total dissolved solids, and chlorophyll concentration). A null model of species co-occurrence was applied to determine randomness in species associations. All sites revealed low species richness (< 6); the calanoid copepod Boeckella gracilis Daday, 1902 was present in all sites. The results of the null model indicated randomness or absence of regulatory factors in species associations. Only few species occur in practically all localities. Also, a significant inverse association between chlorophyll concentration with percentage of calanoid copepods and a weak direct association between chlorophyll concentration and percentages of cladocerans were found

“…Los resultados revelan que los lagos de la Patagonia chilena poseen una baja riqueza de especies y esto se debe a las condiciones de oligotrofia, lo que concuerda con los datos de estudios anteriores, al igual que estudios realizados para lagos de la Patagonia Argentina (Campos 1984, Soto & Zúñiga 1991, Woelfl 2007Modenutti et al 1998). El zooplancton presente en los lagos y lagunas estudiados se encuentra caracterizado por la dominancia de copépodos calanoí-deos del género Boeckella concordando con lo descrito por Menu-Marque et al (2000).…”

Use of null models to study crustacean zooplankton communities of Chilean inland waters. In lentic ecosystems zooplankton plays an important role in energy transference from primary producers to the top trophic levels. The communities have structured spatial associations regulated by biotic and abiotic factors that generate guild organizations where the species utilize the same resource under different biotic and abiotic conditions. The aim of the present study is to determine the existence of some regulatory spatial pattern or the random presence of inland water zooplanktonic crustaceans in Chile. We studied 85 sites, and applied a null model to species associations. We found that the species associations are explained by regulatory patterns, in agreement with the literature about the important role of trophic status and conductivity in the regulation of species composition. The results also agree with descriptions for lakes in Argentina and New Zealand. KEY WORDSZooplankton, oligotrophy, lagos, Patagonia, species associations. RESUMENEl zooplancton tiene una importante función en las cadenas tróficas de los ecosistemas lénticos, transfiriendo la energía de los productores primarios fotosintéticos hacia los niveles tróficos superiores. Las comunidades animales muestran un patrón de asociación, regulado por factores ambientales bióticos y/o abióticos, en el que las especies de encuentran organizadas en gremios, que utilizan un mismo tipo de recurso de manera similar, y a la vez enfrentando diversos gradientes bióticos y abióticos que afectan su comportamiento y adecuación biológica. Buscamos determinar la existencia de algún patrón regulador espacial o de aleatorización en la distribución espacial de los crustáceos zooplanctónicos de aguas continentales chilenas, cuya diversidad ambiental se ve reflejada en la composición de especies de crustáceos zooplanctónicos. Estudiamos 85 sitios, aplicando un modelo nulo para asociaciones de especies. La distribución espacial de estos crustáceos zooplanctónicos se encuentra establecida por patrones reguladores, lo cual concuerda con la literatura indicando un papel importante de las condiciones tróficas y de la conductividad como reguladores de la composición de especies. Estos resultados concuerdan con descripciones para lagos de Argentina y Nueva Zelanda.
