The authors suggest domestic llamas introduced to the site may have triggered the outbreak.
The English Channel prevents many rockpool species from reaching the UK due to unfavorable ocean currents. This could lead to a decrease in intertidal wildlife richness in the UK as warmer-water species fail to replace threatened ones. As climate change causes sea temperatures to rise, this barrier may prevent species from adapting.
