季节性气候变量影响巴西引进牧场生态系统中蜣螂功能多样性和分类学差异的时间模式

鉴于全球气候和土地植被正在发生变化，了解生物多样性时空模式的基本过程和机制至关重要。在这里，我们研究了季节相关气候变量对巴西引进的牧场生态系统中蜣螂多样性的两个方面（分类和功能）以及不同尺度（α和β）的影响。我们对连续 52 周（包括旱季和雨季）的蜣螂进行了采样。我们利用绝对值和连续取样的变化（Δ，取样之间的差异）将分类和功能变量与季节相关的气候变量（温度、降水和湿度）联系起来。我们发现雨季的物种丰富度和丰度值较高。连续取样之间气候变量的变化仅对蜣螂的功能分散性、时间 β 多样性和物种损失产生影响，而对物种丰富度和丰度没有影响。不过，这些影响取决于季节。在雨季，取样间降水量的增加会导致功能分散性降低，而在旱季则相反。同样，取样间温度值升高会导致蜣螂的时间β多样性和物种损失减少，而在旱季则相反。与季节相关的气候变量对蜣螂分类和功能指标的影响截然不同。分类和功能多样性的时间变化可能是由不同的气候变量驱动的，这些气候变量可能与物种的分类或与其热生态位相关的物种特征有关。

期刊介绍： Ecological Entomology publishes top-quality original research on the ecology of insects and related invertebrate taxa. Our aim is to publish papers that will be of considerable interest to the wide community of ecologists who are motivated by ecological or evolutionary theory. The suitability of a manuscript will usually be assessed within 5 days. We publish full-length Original Articles as well as Reviews, Short Communications, Methods and Natural History papers. In Original Articles, we greatly prefer papers that test specific hypotheses and which have a high degree of novelty. All categories aim for innovative contributions that advance the subject of ecological entomology.
