Distribution patterns of intertidal macroalgae are often investigated to evaluate the efficacy of designated marine protected areas (MPAs), yet those assemblages are threatened by high sea surface temperatures, making them vulnerable to ocean warming. Here, we model the present distribution patterns of macroalgae on rocky intertidal shores of Western Australia and project those patterns onto different future climate scenarios...

Latitudinal biodiversity gradients vary across taxonomic groups and spatial scales, and various environmental factors have been associated with those patterns. However, it remains unknown whether taxonomic groups with strong ecological associations have similar or different latitudinal patterns. Macroalgae are foundation assemblages on rocky intertidal shores and are often inhabited by invertebrates, predominantly polychaetes....
