TL;DR: It is argued that this phase shift is facilitated by poleward-flowing boundary currents that are creating ocean warming hotspots around the globe, enabling the range expansion of tropical species and increasing their grazing rates in temperate areas.

TL;DR: It is shown that grazing impacts on plant abundance are better predicted by producer traits than by large-scale variation in habitat or mean temperature, and that there is a previously unrecognised degree of phylogenetic conservatism in producer susceptibility to consumption.

TL;DR: Sea urchin fisheries have potentially large ecological effects, usually mediated through increases in the abundance and biomass of large brown algae, and although such effects may have important consequences for management of these and related fisheries, only in Nova Scotia, South Korea and Japan is ecological knowledge incorporated into management.

TL;DR: An increase in the proportion of warmwater species (“tropicalization”) as oceans warm is increasing fish herbivory in kelp forests, contributing to their decline and subsequent persistence in alternate “kelp-free” states, and posing a significant threat to kelp-dominated ecosystems in Australia and globally.

TL;DR: Results indicate that bleaching in D. pulchra is the result of temperature-mediated bacterial infections and highlight the potential for warming to influence disease dynamics by stressing hosts, as well as indicating the importance of algal chemical defences.
