Foraging ecology of Vicuña, Vicugna vicugna, in dry Puna of Argentina

open access: yesSmall Ruminant Research, 2010
Abstract Vicuna, Vicugna vicugna, is one of the few large native herbivores of South American and it is considered a keystone resource for the Andean Region. We studied foraging ecology of free ranging vicunas at Laguna Blanca MAB-UNESCO Biosphere Reserve (Catamarca, Argentina), within dry Puna environment. Vicunas showed a stable diet throughout the

Threats and Shifts in Microbial Communities of Salars Associated With Direct Lithium Extraction and Brine Reinjection

open access: yesGlobal Challenges, Volume 10, Issue 9, September 2026.
Lithium for rechargeable batteries is increasingly extracted from brines in high‐Andean salars. Direct Lithium Extraction (DLE) technologies are promoted as sustainable alternatives to conventional evaporation ponds. This work explores how brine modification and reinjection may affect microbial communities and ecosystem functioning, highlighting the ...

Food limitation reduces risk avoidance by prey, but does not increase kill rates in a simple predator–prey system

open access: yesEcosphere, 2023
Prey often induce antipredator behaviors when balancing food acquisition against safety. The starvation–predation hypothesis (SPH) posits that, during food shortages, the risk of starvation requires prey to forego antipredator behavior to increase ...

Assessing soil and native high Andean grassland quality under grazing: A case study from the wet Puna of Peru

open access: yesGrassland Science, Volume 72, Issue 3, Page 163-174, July 2026.
Abstract High Andean grasslands are vulnerable to changes in their nutritional quality and carbon sequestration capacity, especially in grazing systems. This study evaluated soil quality and native grasses by measuring carbon, physicochemical parameters, and the nutritional quality of predominant species in the wet Puna of Junín, Peru.

PERFIL BIOQUÍMICO SANGUÍNEO HEPÁTICO DE VICUÑAS (Vicugna vicugna) CRIADAS EN CAUTIVERIO EN LIMA [PDF]

open access: yes, 2013
The blood biochemical liver profile in vicunas (Vicugna vicugna) was determined using 31 animals reared in captivity in two zoological parks in the city of Lima, Peru. Blood was collected by puncture of the jugular vein to measure total (BT), direct (BD)

Actinobacillus vicugnae sp. nov., isolated from alpaca (Vicugna pacos)

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2019
Ten strains of an Actinobacillus-like organism were isolated from alpaca (Vicugna pacos) in the UK over a period of 5 years, with no known epidemiological linkages. The isolates are distinct, based on both phenotype and genotype, from any previously described Actinobacillus species.

ASIP Variants in Livestock: It's Not Black and White

open access: yesAnimal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Fur and feather pigmentation play an important role in the survival and reproduction of many species, as well as in selective breeding and agriculture. The synthesis of pigment molecules, eumelanin and pheomelanin, is partially regulated by the agouti signalling protein (ASIP) encoded by the ASIP gene.
