Ordinations portraying temporal shifts in Lake Erie’s (a, b) environment, (c, d) prey- species composition, and (e, f) prey-trait composition during 1969–2018 (‘69–‘18). Years in (a, c, e) progress temporally across a color gradient from yellow to blue, with orange and purple representing intermediate decades. In (c), text color indicates which prey are preferred (black text) versus less-preferred (red text) by Lake Erie walleye. Relationships between time and NMDS axis 1 (blue lines) and axis 2 (black lines) are illustrated in (b, d, f) to show which years are associated with large directional shifts in the ordinations.
