Artificial perches can provide an important supply of seeds and contribute to ecological restoration. In the present study, we verified the effectiveness of artificial perches for the dispersal of seeds in an area of the southwest Brazilian Amazon. We conducted the study on the Catuaba Experimental Farm in State of Acre, Brazil, from March 2016 to March 2017. We installed seed traps with artificial perches and control traps at different distances from the adjacent forest. We collected 19,865 seeds in boxes under the artificial perches and 1300 in the control traps. There was greater richness of plant species and abundance of seeds in the boxes under the artificial perches when compared with the control traps. The artificial perches at a distance of 40 m from the adjacent forest presented a greater species richness and distinct composition of plants. The quantity of dispersed seeds did not correlate with precipitation, although there was a correlation between rainfall and the fresh seed mass. The artificial perches were efficient at dispersing seeds and are a low-cost technique that can be used as a strategy for the regeneration of forests in degraded areas.

用于在巴西亚马逊西南部支离破碎的景观中供应种子的人工栖息地

人工栖息地可以提供重要的种子供应并有助于生态恢复。在本研究中，我们验证了人工栖息地在巴西亚马逊西南部地区传播种子的有效性。我们于 2016 年 3 月至 2017 年 3 月在巴西阿克里州的卡图巴实验农场进行了研究。我们在与相邻森林不同距离的位置安装了带有人工栖息地的种子诱捕器和控制诱捕器。我们在人工栖息地下的盒子中收集了 19,865 粒种子，在控制陷阱中收集了 1300 粒种子。与对照诱捕器相比，人工栖木下的箱内植物种类更加丰富，种子更加丰富。距邻近森林 40 m 处的人工栖息地表现出更大的物种丰富度和独特的植物组成。尽管降雨量与新鲜种子质量之间存在相关性，但分散种子的数量与降水量无关。人工栖息地可以有效地传播种子，并且是一种低成本技术，可用作退化地区森林再生的策略。
