2017 Troubling disease syndrome in
endangered live Patagonian huemul deer from the Protected Park Shoonem: unusually high
prevalence of osteopathology. Biomed. Central Res. Notes. 10:739.
The first-ever radio-collaring of 3 male huemul in Argentina and 3
females, plus a fresh female carcass showed that 86% were diseased, including lameness,
exfoliation of 2–7 incisors, other cranial osteopathologies, and muscle atrophy. The nexus
to nutritional ecology of huemul likely is inaccessibility to most fertile lowlands and traditional
winter ranges, elimination of migratory traditions.

Preliminary data on movements and health condition of the first radio-collared huemul
population study in Argentina. IUCN DSG Newsletter Nº30.
For the first time in Argentina, radio-telemetry collars were placed on a
group of huemul to better understand the factors behind the population’s failure to
recover. Six adult huemul (3 of each gender) were captured in six days of winter 2017, inside
Shoonem Protected Park. Despite the outwardly healthy appearance of each radio-collared
huemul on the last observation date (January 25, 2018), we identified clinical symptoms of
disease in 5 of these 6 animals during their capture. Movement distances from the winter capture
site to maximum summer distance recorded were 187% greater for females than males. Potential
influences from recreational activities were noted.

Radio marking the first group of endangered Patagonian huemul deer in Argentina.
Mastozoología Neotropical, in press.
Huemul were
radio-collared in the Protected park Shoonem during six winter days. Encountering huemul each
day averaged 93 minutes (17 groups, 37 individuals). Spotting until darting an animal averaged
46 minutes; darting distance averaged 15.7 m; and darting until recovery averaged 45.5 minutes.
Ten capture attempts were made, of which six were successful. Compared to the only huemul
previous radio-collared in Argentina (2016), the present operation required 96.5% less
man-days/animal. Of marked huemul, 86% presented clinical pathologies, best explained by
restriction to marginal if not sink areas, or ecological traps. This operation allowed the first-ever
marking of huemul bucks in Argentina, and a group of six huemul.

Un investigador independiente del CONICET en el Parque Nacional “Nahuel Huapi” (Administración de Parques Nacionales), realizó recientemente en el Parque Protegido Municipal Shoonem (localidad Alto Río Senguer, Provincia del Chubut) una investigación en la que mediante la captura de 6 huemules (3 hembras y 3 machos)- marcados con radio collares – pudieron corroborar, a partir observar diferentes síntomas, la alta prevalencia de osteopatología, enfermedad que afecta los huesos.
