Analysis of cytogenetic differentiation in selected species of the family Camelidae: Vicugna pacos and Vicugna vicugna [PDF]
The aim of this study was to analysis of cytogenetic differentation in two species: Vicugna pacos and Vicugna vicugna . Cytogenetic analysis based on blood culture technique. Blood culture were set up in culture medium Limphogrow and Lymphochrome. The cells growth, after 71 hours, was kept in metaphase using colcemid.

Vicuñas (Vicugna vicugna), Wild Andean Altiplano Camelids [PDF]
In these case studies, vicuñas are presented as biocultural components of the Andean altiplano’s socioecological landscape. The environmental history of vicuñas is related to the multiple values of the species, especially of its appreciated fiber as a nature contribution to people. Vicuñas were in risk of extinction, but thanks to conservation policies,

The vicuna is a high Andean wild camelid that lives year-long in groups. We analyzed the social organization of 98 marked vicunas after capture and live shearing, focusing on group composition, spatial patterns, territoriality and habitat use. The social units analyzed were families, bachelor groups and solo animals.

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.
