Gastrointestinal parasite diversity in two contrasting guanaco (Lama guanicoe) populations of Argentina: Comparing Chacoan and Patagonian populations.

Veterinary Parasitology: Regional Studies and Reports
The guanaco (Lama guanicoe), the largest wild artiodactyl in South America, shows contrasting population trends across its distribution. While more than two million individuals persist in continental Patagonia, only two relict populations remain in the ...

Modelling the abundance and productivity distribution to understand the habitat–species relationship: the guanaco (Lama guanicoe) case study

Wildlife research (East Melbourne), 2020
Context. The conservation of large wild herbivores presents a challenge posed by the fact that their broad habitat requirements overlap with various human activities.

Daylight effect on melatonin secretion in adult female guanacos (Lama guanicoe)

Reproduction in Domestic Animals, 2017
ContentsThe wild South American camelids developed a strategy of seasonal reproduction during spring and summer with singleton birth. The photoperiod is one of the factors that may modulate this seasonality where light would be translated into a hormonal signal.

Spatial variation of guanaco (Lama guanicoe) densities influenced by natural and anthropogenic variables in Southern Andean Precordillera (Argentina)

Studies on Neotropical Fauna and Environment
The spatial distribution of ungulate densities is determined by their decisions on habitat selection, modulated by environmental characteristics and human activities. Poaching and habitat degradation are threats to the guanaco, a native herbivore of arid

Endocrine changes during pregnancy, parturition and post-partum in guanacos (Lama guanicoe)

Animal Reproduction Science, 2009
Plasma concentrations of progesterone (P4), estradiol-17beta (E2), estrone (E1) and estrone sulfate (E1S) were measured during gestation in eight guanacos kept in captivity. Gestational length was 346.1+/-9.8 days. P4 plasma concentrations increased after ovulation and remained elevated until parturition.

MINIMALLY INVASIVE METATARSAL FRACTURE REPAIR WITH LOCKING PLATES IN A GUANACO (LAMA GUANICOE)

Journal of Zoo and Wildlife Medicine, 2014
An open grade I transverse diaphyseal fracture of the metatarsal bone in a 5-yr-old female guanaco (Lama guanicoe) was successfully stabilized with a locking plate system, which is a minimally invasive approach. A conical coupling screw-plate locking system with 3.0-mm-thick plates and 3.5-mm locking head screws was applied, after closed and indirect ...

Health evaluation of free-ranging guanaco (Lama guanicoe).

Journal of zoo and wildlife medicine : official publication of the American Association of Zoo Veterinarians, 1998
Twenty free-ranging guanaco (Lama guanicoe) in Chubut Province, Argentina, were immobilized for health evaluations. All but two animals appeared to be in good condition. Hematology, serum chemistry, and vitamin and mineral levels were measured, and feces were evaluated for parasites.

Non-genetic factors affecting morphometric and fleece traits in guanaco (Lama guanicoe guanicoe) populations from Argentinean Patagonia

Small Ruminant Research, 2010
Abstract Lama guanicoe guanicoe is the guanaco subspecies located in the Argentinean Patagonia. It is of particular interest to characterize these populations as it is a native species and a high quality fibre production genetical resource. With the aim of describing phenotipically Lama guanicoe guanicoe populations, 262 specimens were sampled.
