Dominant Species: Marine

You cannot place a pawn on an action space where you already have a pawn; to use that action again you must first spend a turn retrieving that pawn (placement vs. retrieval rules). (p.9)

"Matching" is the number of element discs on a tile that match your species' elements, and "dominance" is determined by comparing matching counts between species on that tile to resolve control and scoring when you Dominate. (p.7; Domination action rules p.17)

The food chain slides as part of resolving the Abundance action (the slide happens during that action), and elements are reseeded according to the reseed timing specified during Abundance and the Reseed/Resupply rules and events. (p.10; reseed events/endgame p.24)

When you resolve Tectonics you place Vent tiles and follow the procedure for removing/returning species from affected tiles, and you score any bonus VPs awarded by the Tectonics placement if the stated conditions are met. (p.14)

Evolution cards are selected and resolved during the Evolution action in the order shown, and evolution tiles are scored using the tile scoring table and the Evolution action steps. Specific card effects and resolution details are listed with the evolution rules. (tile scoring & Evolution action p.16; card definitions p.18–21)

Regression is an action with a defined resolution sequence and limits: you follow the Regression action steps to remove traits or suffer the regression effects, respecting the limits described in the Regression rules. (p.12)
