报告简介：

Biodiversity is a complex and multi-dimensional concept, with its components varying across scales and sampling efforts. Set theory provides a mathematical framework to elucidate the relationships among the scale-dependent diversity partitions. While the standard scheme of biodiversity partitioning focuses on alpha and beta components, it is insufficient to provide a complete picture of biodiversity. Instead, zeta diversity is a powerful tool that can explain patterns of biodiversity components such as turnover, occupancy frequency, endemism, distance decay, and accumulation. Zeta diversity of order n simply describes the number of species common to n sites and declines along its orders. The regression of zeta diversity components against candidate assembly processes can help tease apart drivers of species turnover and accumulation and differentiate those contributed largely by rare versus increasingly common species. Let’s walk through a forest and decipher its structure and dynamics with the lens of zeta mathematics.
