The paper presents 19 identified species of aphid parasitoids belonging to eight genera in the high altitudes of Central and South America, along with seven unidentified species. Faunal analysis indicates that most of the lowland areas are inhabited by a set of pan-tropical, cosmopolitan, and Nea...
Endemic scrub typhus was recently detected on Chiloé Island in southern Chile. We report a series of cases, acquired over a wide geographical range in continental Chile during 2016-2018, demonstrating that this emerging rickettsial infection is also found on the mainland of South America.
Ammonites are abundant and well preserved in the Tithonian-Valanginian (Upper Jurassic eLowerCretaceous) sedimentary successions of the central Chilean Andes, known as the Lo Valdes and Ba~nos delFlaco Formations. A total of 1429 ammonites were collected from these stratigraphic units and thefol...
Parasitological studies in Anseriformes from Chile are scarce, with only 2 studies in the black-necked swan Cygnus melancoryphus Molina, 1792. Thus, the aim of the present survey was to contribute with new parasitic records for this swan. Necropsy was performed in the digestive tract of 46 C. mel...
The prevalence of Toxoplasma gondii in free-ranging chickens is a good indicator of the prevalence of T gondii oocysts in the soil because chickens feed from the ground. The prevalence of T gondii in 85 free-range chickens (Gallus domesticus) from Chile was determined. Antibodies to T gondii were...

We determined the seasonal diet of the Andean fox Lycalopex culpaeus in three habitats in the Atacama Desert, northern Chile, by analyzing their scat contents. We estimated the biomass and the number of individuals of each prey species consumed and compared our results with those of other studies...

Diverse hypotheses have been proposed with the aim to explain the extinction of Late Pleistocene/Holocene mammals, including the Megafauna from America. Some authors support that human being was the direct responsible of extinction by means of intensive hunting, as proposed by the 'blitzkrieg' or...

Knowledge of trophic ecology is fundamental for understanding feeding strategies and niche dynamics, which can provide information on the vulnerability and conservation status of some poorly known species, such as Liolaemus monticola, a rock-dwelling lizard endemic to the central Andes of Chile. ...

A new species of the genus Acaulospora (Glomeromycetes) was found in several mountainous to high mountainous grasslands in Switzerland and Southern Chile, at 1850-2050 m and 550-1600 m asl, respectively. The species has yellow-white to creamy and regularly globose to subglobose spores with a diam...
