Macroecology and phylogeny: the effects of evolutionary history on rarity and extinction risk in Australian vertebrates.

我们将结合澳大利亚脊椎动物的生态和系统发育分析，展示物种形成的历史过程如何塑造现存物种的丰度和地理范围，范围和丰度的变化与物种年龄的关系，以及选择性灭绝。我们的分析将为澳大利亚脊椎动物物种多样性的产生过程提供新的线索。我们还将对生物物种稀有和容易灭绝的原因有新的了解，这将导致更好地识别和管理濒临灭绝的物种。

We will combine ecological and phylogenetic analysis of Australian vertebrates to show how abundance and geographic range in living species has been shaped by the historical processes of speciation, transformations of range and abundance in relation to species age, and selective extinction. Our analysis will throw new light on the processes that have generated species diversity in Australian vertebrates. We will also gain new understanding of the causes of rarity and vulnerability to extinction among living species, which will result in better identification and management of species at risk of extinction.
