The Brazil nut tree: species interdependence in the rainforest

Brazil nut trees (Bertholletia excelsa) are dependent on several animal species for their survival. These large canopy trees found in the Amazon rainforest rely on the agouti, a ground-dwelling rodent, for a key part of their life cycle. The agouti is the only animal with teeth strong enough to open their grapefruit-sized seed pods. While the agouti eats some of the Brazil nut's seeds, it also scatters the seeds across the forest by burying caches far away from the parent tree. These seeds then germinate and form the next generation of trees. For pollination, Brazil nut trees are dependent on Euglossine orchid bees. Without these large-bodied bees, Brazil nut reproduction is not possible. For this reason, there has been little success growing Brazil nut trees in plantations—they only appear to grow in primary rainforest.


巴西坚果树：在热带雨林里的相互依存
在自然环境中，巴西坚果树（Bertholletia Excelsa ）的生长取决于几个动物物种。人们发现，在亚马逊河的雨林中，这些大型树木离不开一种叫做Agouti的地面啮齿动物，这种动物在巴西坚果树生命周期里扮演者一个关键角色。Agouti的牙齿很锋利，能咬开葡萄大小的坚果荚。当Agouti吃掉一些巴西坚果的种子后，它会在距离果树较远的地方埋藏匿一些种子，于是种子被带到了森林里的其它地方。随着这些种子的发芽，一株株巴西坚果树破土而出。巴西坚果树木是依赖于Euglossine兰花蜜蜂来授粉，如果没有这些大蜜蜂，这些树是不可能结出坚果的。正是基于这些因素，巴西坚果的树木种植园面积虽然日益增长，但增长缓慢―――它们最适宜在雨林地带生长。
