Fig 4. Results of fitting environmental variables onto species ordination.

The increasing gradient of the environmental variable is indicated by the vector direction. The vector length is proportional to the correlation between the variable and the ordination pattern of the species. Species abbreviations are (taxonomical order; see S1 Table): Eel (Eelpout, Licenchelys spp.); Dov (Dover sole, Microstomus pacificus); Dee (Deep sea sole, Embassichthys bathybius); Pac (Pacific halibut, Hippoglossus stenolepis); Rat (Rattail, Coryphaenoides spp.); Roc (Rockfish, i.e. Sebastidae); Bac (Blackfin poacher, Bathyagonus nigripinnis); Sab (Sablefish, Anoplopoma fimbria); Hag (Hagfish Eptatretus stoutii); Sal (Salp, Salpidae); Dum (Dumbo octopus, Grimpoteuthis sp.); Squ (Squid Gonapus sp.); Buc (Buccinids, Neptunidae); Bri (Brittle star, Ophiuroidea); Sf1 (Starfish, Asteroidea); Sf2 (Starfish, Zoroasteridae); St3 (Hippasteria sp.); Hol (Holoturian, Holoturoidea); Her (Hermit crab, Diogenidae); Sca (Scarlet king crab, Lithodes couesi); Gro (Grooved tanner crab, Chionnecetes tanneri); Sma (Small crabs); Cte (Ctenophore, Bolinopsis infundibulum); Scy (Scyphomedusa, Poralia rufescens); Din (Dinner plate jelly, Solmissus sp.); Tra (Traquimedusa, Voragonema pedunculata).
