Taxonomic and biogeographical status of guanaco Lama guanicoe (Artiodactyla, Camelidae)

Mammal Review, 2006
ABSTRACT We review the status of the four currently recognized guanaco Lama guanicoe subspecies, and provide information about their taxonomy and distribution. The success of guanaco in inhabiting open habitats of South America is based mainly on the flexibility of their social behaviour and ecophysiological adaptations to harsh environments. Lönnberg

Differential Bone Survivorship and Ontogenetic Development in Guanaco (Lama guanicoe)

International Journal of Osteoarchaeology, 2011
ABSTRACTThis paper presents the results of a taphonomic research programme conducted over the past 5 years. The main objective of the programme is to investigate differential survivorship in guanaco (Lama guanicoe) bones, taking into account the ontogenetic development of this species and the densitometric characteristics of its skeletal parts.

Challenges and opportunities in mitigating sarcoptic mange in wild South American camelids

The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
Wild South American camelids—vicuña and guanaco—face threats from sarcoptic mange, a contagious skin disease linked to severe population declines. Despite its impact, major gaps remain in understanding disease dynamics. This review summarizes current knowledge, identifies key data and management gaps, and outlines urgent actions for effective ...

El dimorfismo sexual en guanacos (Lama guanicoe). Una evaluación osteométrica de elementos poscraneales

Revista del Museo de Antropologia, 2009
In wild-living populations adult camelids are mainly sexed by observing their social and reproductive behavior, and on occasion, their genitalia. Both biologists and archaeologists usually assume the absence of clearly identifiable sexually dimorphic ...
