Beta diversity of demersal fish assemblages in the North-Eastern Pacific: interactions of latitude and depth by Anderson, Marti J, Tolimieri, Nick, Millar, Russell B

“…Knowledge of broad-scale global patterns in beta diversity (i.e., variation or turnover in identities of species) for marine systems is in its infancy. We…”

Significant shifts in latitudinal optima of North American birds by Martins, Paulo Mateus, Anderson, Marti J, Sweatman, Winston L, Punnett, Andrew J
