The crustacean zooplankton in Chilean coastal lagoons has been poorly studied, and the scarce studies available would indicate the presence of low numbers of species, variable according to the degree of oligotrophy. The aim of the present study was to give a first characterization of crustacean z...

The zooplankton in South American saline waters is mainly dominated by copepods at salinities lower than 90 g/l, whereas at salinities above 90 g/l Artemia sp. is totally dominant. The aim of the present study is to analyse the salinity range of halophilic copepods on the basis of a literature re...

The crustacean zooplankton of Chilean inland waters are characterized by abundant calanoid copepods, mainly from the genus Boeckella. The present study aims to update the distribution of Boeckella gracilis in the inland waters of the Araucania region (38-39°S) and to use null model analysis to un...

Los crustáceos zooplanctónicos en aguas continentales chilenas están caracterizados por la abundancia de copépodos calanoideos, principalmente del género Boeckella. El objetivo del presente trabajo es actualizar la distribución de esta especie en aguas continentales de la región de la Araucanía (...

River systems of Central Chile are short, steep and fast flowing. They are characterized by discharge regimes dominated by rainfall and snowmelt. Invertebrate fauna is highly endemic. This study aimed to describe the community structure of invertebrate in eight river systems in Central Chile (33-...

Os sistemas fluviais do Chile central são curtos, íngremes e fluem rapidamente. Eles são caracterizados por regimes de descarga dominados por chuvas e neve derretida. A fauna de invertebrados desses sistemas fluviais é altamente endêmica. O objetivo do presente estudo foi descrever a estrutura da...

The zooplankton assemblages in deep, mostly oligotrophic northern Patagonian lakes are characterized by a low species number and a marked dominance of calanoid copepods, as well as often by the presence of large mixotrophic ciliates (Stentor). In the present study, data collected in field work on...

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 interventio...

The benthic crustaceans in Chilean rivers and streams are characterized by their marked endemism and low species number. Ecological studies have indicated that some species may be used as indicators of water quality, considering the involvement of river basins in human agricultural, industrial, a...

The lakes of Chiloé Island have a high dissolved organic carbon concentration (known as “humic”) and show a connection with brackish water. They also display a high species richness of crustacean zooplankton. The aim of the present study is to characterize the potential factors that explain crust...

With their ultraoligotrophic status, the Chilean North Patagonian lakes have mixotrophic ciliates in their pelagic environments as producers, whereas the primary consumers are crustaceans that are low in abundance and species numbers. The aim of the present study was to determine the potential gr...
