... 69 Given the benefits of phylogenetic diversity, the contributions of rare species are important to 70 clarify in light of ongoing species losses (White et al., 2023). 71 Rarity can be categorized in multiple ways in terms of small population size, small range 72 size, narrow habitat specificity, or combinations thereof (Rabinowitz, 1981). Here we 73 investigate two major axes of rarity: local abundance and range size. ...
