Abstract Background Despite their regional economic importance and being increasingly reared globally, the origins evolution of llama alpaca remain poorly understood. Here we report reference genomes for llama, guanaco vicuña (their putative wild progenitors), compare these with published genome, resequence seven individuals all four species to better understand domestication introgression between alpaca. Results Phylogenomic analysis confirms that was domesticated from vicuña. Introgression...
Limited mapping of migrations hampers conservation
Abstract Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 International Union for Conservation of Nature (IUCN) called development a “Green List Species” (now IUCN Green Status Species). A draft framework assessing species’ progress toward recovery, published 2018, proposed 2 separate but interlinked components: standardized method (i.e., measurement against benchmarks viability, functionality, preimpact distribution) determine current status (herein...
ABSTRACT We review the status of four currently recognized guanaco Lama guanicoe subspecies, and provide information about their taxonomy distribution. The success in inhabiting open habitats South America is based mainly on flexibility social behaviour ecophysiological adaptations to harsh environments. Lönnberg described first L. g. cacsilensis , at beginning 20th century. Forty years later Krumbiegel voglii skull measurements pelage colouration. other two huanacus were classified as...
A comprehensive study of the phylogeography and population genetics largest wild artiodactyl in arid cold-temperate South American environments, guanaco (Lama guanicoe) was conducted. Patterns molecular genetic structure were described using 514 bp mtDNA sequence 14 biparentally inherited microsatellite markers from 314 samples. These individuals originated 17 localities throughout current distribution across Peru, Bolivia, Argentina Chile. This confirmed well-defined differentiation...
Four camelid species exist in South America: two wild, the guanaco (Lama guanicoe) and vicuña (Vicugna vicugna), domestic, alpaca pacos) llama glama).However, origin of domestic has been a matter debate.In present study, variations chromosome G banding patterns mitochondrial gene sequences have used to study classification alpaca.Similar band structure were observed all four Lamini species, these turn similar bands described for camels, Camelus bactrianus.However, fine consistent differences...
Competition arises when two co-occuring species share a limiting resource. Potential for competition is higher have coexisted short time, as it the case herbivores and livestock introduced in natural systems. Sheep, late 19th century Patagonia, bear great resemblance size diet to guanaco, main native herbivore Patagonia. In such circumstances, could be expected that compete one of them displaced. We investigated spatial overlap habitat selection by coexisting sheep guanaco winter summer....
Abstract Human‐wildlife conflicts (HWCs) are one of the most critical conservation challenges worldwide. Large carnivores frequently at centre these because perceived and real threats they pose to livestock human safety. Determining social perceptions attitudes towards plays a vital role in shaping policies that ensure sustainable coexistence humans wildlife. We conducted structured interviews with ranchers proposed Torres del Paine UNESCO Biosphere Reserve (Chilean Patagonia) 2011 2018....
The presence of humans and large carnivores in shared landscapes presents unique challenges for wildlife conservation management. This study explores the temporal activity patterns tourists pumas Puma concolor using camera traps to understand potential encounters between two groups Patagonia National Park, Chile. park, characterized by a cold temperate climate with diverse vegetation, spans over 304 527 hectares. Data collected from August 2020 March 2022 reveal distinct tourists, being...
Abstract Effective conservation management of threatened species with transboundary distributions is a challenge, requiring international coordination to ensure that country-specific actions align regional imperatives. Many efforts overlook needing attention and fail incorporate the field expertise local researchers in regional-level assessments. Here we focus on taruka Hippocamelus antisensis , little-studied deer Central Andes Ecoregion South America. Since 2016, experts, managers...
Guanacos (Lama guanicoe) are the most important native herbivorous species in South American steppes and dominant ungulate a fauna rich rodents but poor large mammal species. Between 2 4 subspecies usually recognized within Lama guanicoe, based on subtle morphological differences geographic distribution. To evaluate whether molecular variation is consistent with latter hypotheses, we analyzed complete cytochrome-b partial control region mitochondrial DNA sequences of L. guanicoe from 22...
Summary Investigations of genetic diversity and domestication in South American camelids (SAC) have relied on autosomal microsatellite maternally‐inherited mitochondrial data. We present the first integrated analysis domestic wild SAC combining male female sex‐specific markers (male specific Y‐chromosome female‐specific mtDNA sequence variation) to assess: (i) hypotheses about origin camelids, (ii) directionality introgression among and/or taxa as evidence hybridization (iii) currently...

Abstract Females in several ungulates transfer milk to non‐filial (NF) offspring, a process known as allonursing. This behavior is less common monotocous species, including most ungulates, and it has been associated with parasitic of calves or mothers who have lost their own offspring. To examine whether the ‘steal’ from females fail discriminate guanacos, allonursing was observed. If theft drives allonursing, should reject NF they search for calves, attempting suckle alien adopt parallel...
Niche description and differentiation at broad geographic scales have been recent major topics in ecology evolution. Describing the environmental niche structure of sister taxa with known evolutionary trajectories stands out as a useful exercise understanding requirements. Here we model distribution recently resolved phylogeography guanaco (Lama guanicoe) lineages on western slope southern Andes. Using maximum entropy framework, field data, information climate, topography, human density,...
Fifteen guanacos were introduced to Staats Island in the Falklands/Malvinas archipelago from Patagonia 1930s. Twenty five years later, population was culled 300 10-20 individuals, but quickly rebounded a of almost 400 animals that today retain genetic signature founding event and later bottleneck. The goals this study (i) make assessment island through comparisons with mainland populations simulations, (ii) assess likely source-population guanacos. Genetic variation estimated 513 bp...
Guanaco (Lama guanicoe) is a protected and widely distributed ungulate in South America. A poacher, after killing guanacos Valle Chacabuco, Chilean Patagonia, transported stored the meat. Samples were retrieved by local police but suspect argued that meat was from horse. Mitochondrial cytochrome b gene (774 pb), 15 loci microsatellites, SRY used to identify species, number of animals their population origin, sex animals, respectively. Analysis revealed samples came female (absence gene)...
The vicuña (Vicugna vicugna) is the most representative wild ungulate of high Andes South America with two recognised morphological subspecies, V. v. mensalis in north and vicugna south its distribution. Current population size (460,000-520,000 animals) result recovery programs established response to 500 years overexploitation. Despite vicuña's ecosystemic, economic social importance, studies about their genetic variation history are limited geographically restricted. Here we present a...
