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

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.
