Bird memes present at different fragments (kipukas) in the Big Island of Hawaii

This datafile shows the presence or absence of different acoustic memes (i.e. syllables) in a fragmented landscape in the Big Island of Hawaii (USA). The fragments (i.e. kipukas) were formed by lava flows. The data is for four native Hawaiian forest birds: 'i'wi, 'elepaio, 'amakihi and 'apapane. In the files, each row represents a fragment and each column a meme. We show if a meme is vocalized in a fragment. Recordings taken in 2014-2015. See publication in Oikos for more details.本数据集文件展示了美国夏威夷大岛破碎化景观内，各类声学鸣唱模因（acoustic memes，即鸣唱音节）的存在状态。该景观中的破碎斑块（kipuka）由熔岩流作用塑造而成。本数据集涵盖四种夏威夷原生林鸟：‘i’wi、‘elepaio、‘amakihi及‘apapane。数据文件中，每一行对应一处栖息地斑块，每一列对应一个声学鸣唱模因，用于标注该斑块内是否存在对应鸣唱音节的发声记录。本次录音采集于2014至2015年，更多细节可参阅发表于《Oikos》的相关研究成果。
