摘要

火山喷发可能与喷发出的气体和沉积的火山灰有关,从而导致动物的健康发生变化。我们评估了2011年Puyehue-Cordón Caulle火山喷发是否对生活在巴塔哥尼亚西北部受火山喷发影响最严重地区的受威胁的安第斯秃鹰(Vultur gryphus)的健康产生影响。我们研究了秃鹰喷发前后的临床和生化指标。我们还检查了喷发后采样的个体血液中不同金属和类金属的浓度。与发疹过程相关的最常见临床异常是刺激性咽炎。在喷发后采集的秃鹰血液中,白蛋白、钙、类胡萝卜素和总蛋白的浓度下降到该物种报告的参考值以下。我们在喷发后这些秃鹰的血液中发现了不同的化学元素,如砷和镉,有可能对健康产生影响。因此,火山喷发对安第斯秃鹰的健康产生了不同的影响;留在受灾地区似乎代价高昂。然而,与其他动物物种相比,对健康的影响没有那么大,主要与粮食短缺有关,因为与火山爆发有关的牲畜尸体的供应减少。这表明秃鹰相对较好地应对了这一大规模事件。未来的研究需要评估我们发现的健康变化是否会减少这个物种的生存,以及居住在火山地区的成本是否对秃鹰的生活史有任何生态或进化影响。

Natural hazards and wildlife health: The effects of a volcanic eruption on the Andean Condor
ABSTRACT Volcanic eruptions produce health changes in animals that may be associated with emitted gases and deposited ashes. We evaluated whether the Puyehue–Cordón Caulle volcanic eruption in 2011 produced health changes in the threatened Andean Condor (Vultur gryphus) living in the area most affected by the eruption, northwestern Patagonia. We studied clinical and biochemical parameters of condors examined before and after the eruption. We also examined concentrations of different metals and metalloids in the blood of individuals sampled after the eruption. The most common clinical abnormality associated with the eruptive process was irritating pharyngitis. In condors sampled after the eruption, blood concentrations of albumin, calcium, carotenoids, and total proteins decreased to levels under the reference values reported for this species. We found different chemical elements in the blood of these condors after the eruption, such as arsenic and cadmium, with the potential to produce health impacts. Thus, the health of Andean Condors was affected in different ways by the eruption; remaining in the affected area appears to have been costly. However, in comparison to other animal species, the health impacts were not as strong and were mainly related to food shortages due to the decrease in availability of livestock carcasses linked to the eruption. This suggests that condors dealt relatively well with this massive event. Future research is needed to evaluate if the health changes we found reduce the survival of this species, and if the cost of inhabiting volcanic areas has any ecological or evolutionary influence on the condor's life history.

期刊介绍: The Condor is the official publication of the Cooper Ornithological Society, a non-profit organization of over 2,000 professional and amateur ornithologists and one of the largest ornithological societies in the world. A quarterly international journal that publishes original research from all fields of avian biology, The Condor has been a highly respected forum in ornithology for more than 100 years. The journal is one of the top ranked ornithology publications. Types of paper published include feature articles (longer manuscripts) Short Communications (generally shorter papers or papers that deal with one primary finding), Commentaries (brief papers that comment on articles published previously in The Condor), and Book Reviews.
