随着人类对自然界的改造越来越多,许多动物也改变了自己的行为。预测这些反应的程度是保护这些物种的关键一步。例如,某些鸟类将人为物品-特别是塑料材料-放入其巢穴的趋势日益令人关切,因为在某些情况下,这种行为对成年和幼鸟都有有害影响。然而,迄今为止,对这一现象的研究仅限于地理和分类学范围。为了调查人类(包括塑料)筑巢材料使用的全球相关性,我们使用贝叶斯系统发育混合模型和6,147种鸟类记录的筑巢材料数据集。我们发现,控制研究工作后,人为的巢材料的使用与接近人类景观改造,synanthropic(人工)筑巢的位置,繁殖环境,以及物种的巢内已记录的材料的数量。我们还表明,人为巢材料的使用是无关的体重,范围大小,或保护状态。这些结果表明,人为的材料更有可能被包括在巢时,他们更容易获得,以及潜在的物种有更多的灵活性,在巢材料的选择。
As humans increasingly modify the natural world, many animals have responded by changing their behaviour. Predicting the extent of these responses is a key step in conserving these species. For example, the tendency for some species of birds to incorporate anthropogenic items – particularly plastic material – into their nests is of increasing concern, as in some cases this behaviour has harmful effects on both adults and young. Studies of this phenomenon, however, have to date been limited in geographic and taxonomic scope. To investigate the global correlates of anthropogenic (including plastic) nest material use, we used Bayesian phylogenetic mixed models and a dataset of recorded nest materials in 6,147 species of birds. We find that after controlling for research effort, anthropogenic nest material use is correlated with proximity to human landscape modification, synanthropic (artificial) nesting locations, breeding environment, and the number of materials that has been recorded within the species’ nest. We also demonstrate that anthropogenic nest material use is unrelated to body mass, range size, or conservation status. These results indicate that anthropogenic materials are more likely to be included in nests when they are more readily available, as well as potentially by species who have more flexibility in nest material choice.
