The increased activity of aquaculture in Chile involves cultivation of salmonids, oysters mussels and other species such, and to a lesser extent species such as red abalone (Haliotis rufescens) and Japanese abalone (Haliotis discus hannai). The aim of this study was to evaluate the growth rate of...

Calanoid copepods are abundant in South American inland waters and include widespread species, such as Boeckella gracilipes (Daday, 1902), which occurs from the Ecuador to Tierra del Fuego Island. This species occurs under various environmental conditions, and is found in oligotrophic lakes in Pa...

The ecological concepts 'metapopulation' and 'metacommunity' encompass the existence of integrated systems of populations and communities, as units that experience continuous exchange of individuals through migratory activity. These concepts could be applied to crustaceans that inhabit systems of...

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 Chilean north Patagonian inland waters are characterized by their low mineral concentrations. In their original status, many of these ecosystems have native vegetation in their surrounding drainage basins, but in the last decades the native vegetation was replaced by agricultural, urban, and ...

The Puna is a high altitude ecosystem of the Central Andes located in the desert plateaus above 3500 m a.s.l. that covers parts of north-eastern Chile, north-western Argentina, south-eastern Peru and mid-western Bolivia. It is characterised by the presence of endorheic basins. Laguna Lejia is an ...

To date, he fairy shrimps (Anostraca) of Chilean inland waters have been poorly described. Those that were described mainly belong to the genus Branchinecta, and the reports are primarily restricted to shallow seasonal pools at the northern and southern extremes of Chile. The aim of the present s...

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 Atacama is the world's driest desert. It contains various types of wetlands. In general, the diversity and structure of the zooplankton in these wetlands have been very little studied. The object of the present study was to analyse the specific composition and structure of the zooplankton in ...
