“…The largest remnant huemul populations are mostly located in remote mountainous ecosystems in the Chilean coastal Patagonia. Despite their small populations and remoteness, huemul appear to have an important contact with both managed and feral cattle populations (Corti et al 2013). While it is unknown whether diseases are affecting huemul persistence, there is suggesting evidence that in some huemul populations the survival of offspring is low, due to a high percentage of unknown mortality causes (Corti et al 2010).…”

“…Information about viral and bacterial pathogens in native ruminants is very scarce. Bovine viral diarrhea virus (BVDV) was detected in the southern pudu and two Chilean huemuls were found to be exposed to the virus 88,89 . Similar to MAP, BVDV isolates from the southern pudu share molecular characteristics with viruses circulating in cattle, suggesting that livestock are acting as disseminators of pathogens to native wildlife in Chile 70,88 .…”

Knowledge about viral and bacterial pathogens present in wild mammals in Chile: a systematic reviewThis study organizes all available information about viral and bacterial pathogens of wild mammals in Chile. This was done in order to identify pathogens that have been well-documented and recognize those that have not been properly studied, determine the number of articles that have been published annually about this topic and identify regions in Chile that concentrate the highest and lowest number of studies concerning viral and bacterial pathogens. A total of 67 scientific articles published in peer-reviewed journals from 1951 to 2018 were selected for revision. Results indicate that the number of publications has increased per decade but there are years in which no articles were published. Most studies addressed Leptospira, rabies, hantavirus, Mycobacterium avium paratuberculosis (MAP) and distemper. Rodentia, Carnivora, Chiroptera and Cetartiodactyla were the most studied mammal orders. Information about presence/absence of pathogens was found for 44 wild mammal species. Research was mainly carried out in central and southern Chile and the most commonly employed methods for pathogen diagnosis were serology and molecular techniques. Overall, research in wild mammals has been directed towards the evaluation of zoonotic diseases, while vector-borne and non-zoonotic diseases have been mostly neglected by the scientific community over the years.

“…In Argentina, one endemic medium-sized deer (Hippocamelus bisulcus Molina, commonly named as huemul) is the most endangered species of Patagonia (Black-Decima et al 2016), being the flag species for several conservation programs (Flueck and Smith-Flueck 2006;Smith-Flueck et al 2011;Vidal et al 2011). Some authors sustain that this species presented a marked decrease in its geographical distribution due to a combination of several factors, e.g., habitat loss, trade-offs with domestic species (cattle or dogs), poaching, malnutrition, and infectious disease (Díaz and Smith-Flueck 2000;López-Alfaro et al 2012;Corti et al 2011Corti et al , 2013. Several conservation efforts in Southern Patagonia had been conducted without clear knowledge about species habitat requirement and/or the effectiveness of the current natural reserve network (National and Provincial reserves) (Frid 2001;Vila et al 2006;Luque et al 2011;Martínez Pastur et al 2016).The objective of this study was to elaborate a potential HSM for huemul in Santa Cruz province (Argentina).…”

Modeling of potential habitat suitability of Hippocamelus bisulcus: effectiveness of a protected areas network in Southern Patagonia

Introduction: Huemul (Hippocamelus bisulcus Molina) is the most threatened flag species of Southern Patagonia, where conservation efforts were not effective to avoid the retraction of its distribution area. Habitat quality modeling can assist to design better management strategies for regional conservation planning. The objective was to elaborate one habitat suitability map for huemul, defining the environmental characteristics at landscape level, and determining the distribution of the suitable habitat inside the current natural reserve network. Methods: We used a database of 453 records and explored 40 potential explanatory variables (climate, topographic, and landscape variables including human-related ones) to develop one habitat suitability map using the Environmental Niche Factor Analysis (ENFA) for Santa Cruz province (Argentina). We combined the outputs in a GIS project using different shapes, including the current natural reserve network. Results: We defined the potential habitat for huemul, where forest edges and ecotone zones (e.g., mainly alpine environments) were the most important environmental variables, as well as some forest types (e.g., Nothofagus pumilio). Habitat losses were found in the extreme potential distribution areas (northern and southern areas), probably related to the increasing ranch activities. The current natural reserve network maintains approximately half of the huemul potential habitat in Santa Cruz province, where National Parks presented the similar conservation importance than the Provincial natural reserves. Conclusions: Habitat suitability model for huemul can be used as a decision support system for new management strategies at different landscape levels to improve the current conservation efforts.
