Phyloinformatics and biodiversity: developing bioinformatic tools for understanding the dynamics of extinction and invasion within species assemblages

DNA序列数据为研究生物多样性提供了一种令人兴奋的新方法，因为每个生物的基因组都记录了它的进化史。通过分析共存物种的DNA序列，我们可以重建一个生物群落的生态和进化历史。这使我们能够追踪生物多样性随时间的变化，并研究物种组合的状态如何决定哪些物种因灭绝而消失，哪些物种因外来物种的入侵而获得。面对快速变化的环境，了解支配生物多样性随时间变化的因素对于规划未来的保护至关重要。

DNA sequence data provides an exciting new way to study biodiversity, because the genome of each organism records its evolutionary history. By analysing DNA sequences co-existing species, we can reconstruct the ecological and evolutionary history of a biological community. This allows us to track biodiversity changes over time, and examine how the state of a species assemblage determines which species are lost through extinction or gained through the invasion of exotic species. Understanding the factors that govern changes in biodiversity over time is essential for planning for future conservation in the face of a rapidly changing environment.
