Continuing impacts on red deer from a volcanic eruption in 2011

Abstract

In June of 2011, the Puyehue–Cordon Caulle volcanic eruption deposited large amounts of ashes in Chile and Argentina. Although ashes were initially considered innoxious based on water leachates, we found clinical cases of fluoride intoxication in red deer (Cervus elaphus) and domestic herbivores in Argentina. The diagnosis was corroborated by high bone fluoride concentrations. The dynamics of temporal accumulation of fluoride suggested an average increase of 1,000 ppm per year of fluoride in the bone. However, a few deer had fluoride levels, suggesting an accumulation rate of about 3,700 ppm per year. Via recent sampling of deer, we now confirm that bone levels have reached up to 10,396 ppm of fluoride after about 28 months of exposure. Tephra across various sites averaged 548 ppm of fluoride, and due to dry conditions and eolic redeposition of ashes particularly east of the continental divide, clinical fluorosis is expected to continue to intensify. The described impact will reverberate through several aspects of the ecology of the deer, including effects on population dynamics, morbidity, predation susceptibility, as well as other components of the ecosystem, including other herbivores, scavengers, and plant communities.

Acknowledgments

This research was done on private land within a natural reserve of the Argentine Administración de Parques Nacionales (permit 070-2013) with partial funding stemming from the PIP CONICET grant Nr. 11220110100124. The authors are grateful to Juan Jones, Konrad Bailey and Pio Pigorini, Lalo Martinez, and Ricky Aquirre for facilitating access and allowing us to work on their properties. Logistics were provided by DeerLab, Argentina, and we also thank Swazi New Zealand for protective field garments, Rubén Kodjaian for providing our office with crucial logistics via the Hostería El Retorno, and Beat Fuchs for his dedicated field assistance within clouds of tephra. I thank the two reviewers for very constructive comments.
