宏观生态学在很大程度上依赖于比较方法，以确定大规模的模式，并测试可能产生这种模式的替代假设。随着物种及其生活史和生态属性的大型电子数据库的出现和可访问性，生态学家开始寻求共性，并研究涉及范围，丰度和多样性等核心主题的大规模生态假说。例如，生态、生活史和系统发育数据的组合已经使用大物种集进行分析，以检验入侵生物学中的假设。对区域物种清单的分析有助于我们对入侵的理解。在这里，我们研究了几种有效的数据库分析方法。我们回顾了19项比较入侵生物学的研究，每项研究都使用了超过100种植物进行分析，并表明入侵者的成功与七个相关因素有关：短生命周期，非生物（主要是风）传播，大的原生范围大小，非随机分类模式（强调某些科或目），克隆器官的存在，占据干扰的栖息地，以及较早的引入时间。这些受遗传学影响的比较分析使用区域物种清单才刚刚开始，有很大的潜力。
Macroecology depends heavily on a comparative methodology in order to identify large-scale patterns and to test alternative hypotheses that might generate such patterns. With the advent and accessibility of large electronic databases of species and their life history and ecological attributes, ecologists have begun seeking generalities, and examining large-scale ecological hypotheses involving core themes of range, abundance and diversity. For example, combinations of ecological, life history and phylogenetic data have been analysed using large species sets to test hypotheses in invasion biology. Analysis of regional species inventories can contribute cogently to our understanding of invasions. Here we examine several ways in which database analysis is effective. We review 19 studies of comparative invasions biology, each using > 100 species of plants in their analyses, and show that invader success is linked to seven correlates: short life cycle, abiotic (mostly wind) dispersal, large native range size, non-random taxonomic patterns (emphasizing certain families or orders), presence of clonal organs, occupying disturbed habitats, and earlier time of introduction. These phylogenetically influenced, comparative analyses using regional species inventories are only just beginning and have much potential.
