论文摘要
环状树木（Corallus annulatus）是Boid Corallus属目前公认的物种之一。它的分离范围从危地马拉东部到洪都拉斯北部，尼加拉瓜东南部，哥斯达黎加东北部和西南巴拿马，再到安第斯山脉以西的北哥伦比亚。它是哥斯达黎加加勒比海地区唯一发现的Corallus物种，它发生在海拔至少650m，也许高达1,000m。 Corallus annulatus主要发生在原发性和次要低地热带潮湿和潮湿的热带雨林中，似乎确实很少见。除了C. cropanii和C. blombergi（后者与C. annulatus密切相关）外，它是该属的最稀有成员。除了有关栖息地和活动的信息外，关于其自然历史知之甚少。
The Annulated Treeboa (Corallus annulatus) is one of nine currently recognized species in the boid genus Corallus. Its disjunct range extends from eastern Guatemala into northern Honduras, southeastern Nicaragua, northeastern Costa Rica, and southwestern Panama to northern Colombia west of the Andes. It is the only species of Corallus found on the Caribbean versant of Costa Rica, where it occurs at elevations to at least 650m and perhaps as high as 1,000m. Corallus annulatus occurs mostly in primary and secondary lowland tropical wet and moist rainforest and it appears to be genuinely rare. Besides C. cropanii and C. blombergi (the latter closely related to C. annulatus), it is the rarest member of the genus. Aside from information on habitat and activity, little is known regarding its natural history.
