Registro de vicuñas (Vicugna vicugna, Molina 1782) como hospedador de Amblyomma parvitarsum Neumann, 1901 (Acari: Ixodidae) en Bolivia [PDF]

open access: yes, 2011
Adult stage Ixodidae mites were collected from wild vicuna (Vicugna vicugna Molina 1782), captured at three locations from the Área Natural de Manejo Integrado Nacional Apolobamba, in the Department of La Paz, Bolivia. The collected ticks corresponded to

Elements on the move: How ungulate migration expands Alpine biogeochemical footprints

open access: yesJournal of Animal Ecology, EarlyView.
Using a spatially explicit model parameterized with GPS telemetry, we show that migratory and resident red deer play distinct roles in nitrogen redistribution across alpine landscapes. Migrants uniquely transport nitrogen upslope and up elevation, linking ecosystem element pools and revealing how the loss of migration alters large‐scale ecosystem ...

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Coproparasitological evaluation of nematodes and coccidia in a wild vicuña (Vicugna vicugna) population in the Argentinean Andean Altiplano [PDF]

open access: yes, 2016
A parasite screening evaluation was conducted to determine the presence of gastrointestinal nematodes and coccidia in wild vicuñas (Vicugna vicugna vicugna) from Jujuy, in Argentina´s Andean Altiplano.

Layer‐by‐layer soft‐tissue effects on flexion–extension‐dominant passive ex vivo limb joint ROM in quadrupedal mammals: An anatomical contribution to a morphofunctional framework

open access: yesJournal of Anatomy, EarlyView.
Layer‐by‐layer passive ex vivo assessment of flexion–extension‐dominant limb joint ROM across rabbit, pudu deer, chilla fox and pig revealed joint‐, tissue‐ and taxon‐specific responses to progressive tissue removal. Proximal joints often showed increasing ROM, whereas distal joints often showed non‐monotonic responses.

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

Evaluation of a non‐radioactive rapid test for determination of serum progesterone in South American camelids

open access: yesVeterinary Record, Volume 199, Issue 7, Page e327-e330, 3/10 October 2026.
Abstract Background Determination of the serum progesterone (P4) concentration is of high importance in reproductive medicine and may be applied for diagnosing pregnancy in South American camelids. P4 measurements in alpacas and llamas are usually performed using immunoassays, which are time consuming and require appropriate expertise of laboratory ...

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 ...

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.
