在尼加拉瓜,因低沉吼叫而闻名的吼猴正死于一种未知的疾病。最近,在该国的热带森林发现了至少75具吼猴的尸体,并且没有明显的迹象表明其死因。类似的情况最近相继在厄瓜多尔和巴拿马出现。现在,一组科学家正前往尼加拉瓜以查明目前的情况以及这些事件是否相关。来自密歇根大学安娜堡分校的研究人员将和其它几个研究机构合作来验证他们的假设。他们将调查猴子是否正缺少食物或是水(但这可能性不大,因为已经检查的一些猴子的胃里满满的)。他们会查看吼猴是否有和农药或其它污染物发生接触,又或是在吃了含有有毒化合物的植物后中毒。他们还将收集血液和组织样本来测试病原体,包括引起黄热病或寨卡的病毒。吼猴(上图)对黄热病病毒高度敏感,但尼加拉瓜已经许多年没有报告过这种疾病了。目前国内已有24人患上寨卡病毒,但科学家们不知道这种病毒是否会对新世界猴的某个物种产生影响。虽然吼猴不是濒危物种,但国际自然保护联盟已因其栖息地的消失将它们归类为“近危”物种。科学家们警告称,大量的死亡事件可能会导致一些当地吼猴种群的灭绝。而这可能破坏吼猴的家园——热带旱林,因为里面的植物依赖这些以水果为食的猴子来传播种子。

Howler monkeys in Nicaragua are mysteriously dying off

原文摘要:

Howler monkeys, known for their deep-throated roars, are dying from an unknown ailment in Nicaragua. The bodies of at least 75 have been found recently in the country’s tropical forests, with no obvious indication as to why. And similar die-offs have occurred recently in Ecuador and Panama. Now, a team of scientists is heading to Nicaragua to find out what is going on and whether these events are related. The researchers, from the University of Michigan, Ann Arbor, will be working with several other institutions to test their hypotheses. They’ll investigate whether the monkeys are suffering from lack of food or water (unlikely, because some monkeys already examined had full stomachs). They will see whether the howlers came into contact with pesticides or other contaminants or were poisoned after eating plants containing toxic compounds. They’ll also collect blood and tissue samples to test for pathogens, including the viruses that cause yellow fever or Zika. Howler monkeys (above) are highly susceptible to the yellow fever virus, but Nicaragua has not reported any cases of the disease for many years. Zika has sickened 24 people in the country so far, but scientists do not know whether the virus affects any species of New World monkey. Although howlers are not endangered, the International unio for the Conservation of Nature has classified them as “near threatened” because of habitat loss. The mass die-offs could lead to extinctions of some local populations, the scientists warn. And that could harm the howlers’ home—tropical dry forests that depend on these fruit-eating monkeys to spread plant seeds.
