Climate‐driven substitution of habitat‐forming species leads to reduced biodiversity within a temperate marine community
Abstract Aim In marine ecosystems, habitat‐forming species ( HFS ) such as reef‐building corals and canopy‐forming macroalgae alter local environmental conditions and can promote biodiversity by providing biogenic living space for a vast array of associated organisms. We examined community‐level imp...
