Los ensambles zooplanctónicos en los ecosistemas acuáticos chilenos se caracterizan por presentar un bajo número de especies y un alto predominio de copépodos. El objetivo de este trabajo es presentar la diversidad y distribución de crustáceos zooplanctónicos de los órdenes Calanoida y Cyclopoida...

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...

La diversidad del zooplankton en lagos salinos poco profundos de Sudamérica es baja y su distribución depende altamente de la salinidad, la cual varía de moderada a alta. A salinidades menores a 90 g/l predomina el copépodo halofílico Boeckella poopoensis (Marsh, 1906), mientras que a salinidades...

Zooplankton diversity in shallow salt lakes of the Andean countries in South America is low and distribution is highly dependent on salinity, which varies from moderate to high. At salinities lower than 90 g/l, the halophilic copepod Boeckella poopoensis (Marsh, 1906) predominates, whereas above ...

The Torres del Paine National Park is located in the southern Chilean Patagonia. This park has numerous and heterogeneous lakes and ponds with different trophic status and zooplankton composition. The aim of this study was to analyze the influence of trophic status and conductivity on zooplankton...

In Andes Mountains (14-27°S) and Patagonian plains (45-53°S) in Chile, there are numerous shallow saline and sub-saline lakes. These water bodies have important temporal and spatial variation of their salinity caused by mineral composition of their watershed or exposition to arid weather. In this...

The present study conducted at the mangrove ecosystem of Kali estuary. Samples were collected from the three fixed stations for the period of thirteen months from January 2008 to January 2009 at regular monthly interval to identify and quantify the abundance, taxonomy and relative ratio of phytop...

The recently developed dry method for the element determination of single freshwater microcrustacean specimens (Daphnia) using total reflection X-ray fluorescence (TXRF) spectrometry showed that inhomogeneities of the biological material on the glass carriers resulted in some cases in high backgr...

Los ensambles zooplanctónicos en lagos del norte de la Patagonia se caracterizan por su bajo número de especies y marcada dominancia de copépodos calanoideos. En el presente trabajo se colectaron datos de seis cuerpos de agua del Parque Nacional Alerce Andino, los cuales se analizaron usando un í...

The zooplankton assemblages in deep, mostly oligotrophic northern Patagonian lakes are characterized by low species numbers and a marked dominance of calanoid copepods. In the present study, data collected in field work on six water bodies located in Alerce Andino National Park (41°S) were analys...

Chilean Patagonia has protected mountainous areas with evergreen native forests; in which the lakes and rivers, of volcanic or glacial origin, are oligotrophic. In Bulgaria, there are mountainous zones with native forests and associated lakes of volcanic origin. The aim of the present study is to...

La Patagonia de Chile tiene una serie de áreas protegidas con bosques nativos perennes asociados a lagos y ríos oligotróficos y de origen glacial. Por otro lado en Bulgaria hay una serie de zonas montañosas con lagos asociados de origen volcánico o glacial. El objetivo del presente trabajo es rea...
