在我们快速城市化的世界中，利用人为资源的物种比其他物种更有积极的人口趋势，尽管其影响可能取决于它们应对环境变化的能力。我们通过对海雀科的系统发育比较分析来解决这个问题。我们发现，在建筑物上筑巢的物种的数量趋势平均比其他物种表现出更积极的趋势，但随着尾叉深度的增加，在建筑物上筑巢的物种的数量趋势减少（甚至变为负向），这是一种使物种容易受到环境变化影响的装饰。利用人为资源可能会使深分叉尾燕子的种群趋势恶化。
In our rapidly urbanizing world, species utilizing anthropogenic resources would have positive population trends more than others, although its effect might depend on their ability to cope with environmental change. We tackled this issue using a phylogenetic comparative analysis of hirundines (Aves: Hirundininae). We found that species nesting on buildings, on average, showed more positive population trends than others but, population trends of species nesting on buildings decreased (and even becoming negative) with increasing tail fork depth—an ornament that makes species susceptible to environmental change. Utilizing anthropogenic resources might deteriorate population trends of swallows with deeply forked tails.
