The marine fauna of decapod Crustacea, in all its diversity, can be negatively affected as a result of environmental changes, both on a local or a global scale. The present study aims to report the existence of Cyrtograpsus angulatus Dana, 1851, on the northern Patagonian coast, while concurrentl...

Our knowledge on the status of Hemigrapsus crenulatus (H. Milne Edwards, 1837) populations along the Chilean coast is scarce. The aim of the present study was to quantitatively estimate the spatial distribution and abundance of Hemigrapsus crenulatus in the Puerto Cisnes estuary (44°S, Aysen regi...

Ancient lakes are renowned for their exceptional diversity of endemic species. As model systems for the study of sympatric speciation, it is necessary to understand whether a given hypothesized species flock is of monophyletic or polyphyletic origin. Here, we present the first molecular character...

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...

Northern Chilean Patagonia has numerous pristine lakes associated with perennial native forests. The present study looks at optical properties in visible, close, and medium infrared wavelengths in mountain lakes of Alerce Andino National Park (41 degrees S). These lakes have associated Nothofagus...

Northern Chilean Patagonia has numerous pristine lakes associated with Nothofagus and Araucaria araucana forests. The present study consists of a study of optical properties in visible, close, and medium infrared wavelengths in mountain lakes surrounding Llaima Volcano lakes that have associated ...

The crustacean zooplankton in Chilean Patagonian lakes is characterized by a marked dominance of calanoid copepods when under an oligotrophic status. The aim of the present study was to analyse the number of eggs and the relation of that feature with the total length of females of calanoid and cy...

The calanoid copepod, Boeckella poopoensis Marsh, 1906 inhabits shallow saline ponds located in the Andes mountains in Argentina, Bolivia, Chile, and Peru, as well as in the plains of southern Argentina. The species is halophilic and can tolerate salinity levels of 1 to 90 ppt. This paper describ...

The longest river in Chile, the Loa, is in fact found in the Atacama Desert in the far north of the country. Being an important resource for the dry Antofagasta region, this river experiences high anthropogenic impacts due to water use for mining, urban, and agricultural activities. Unfortunately...
