'Shifts in the geographical distributions of marine species  cause changes in community composition and interactions . Thereby, climate change will reassemble communities and affect biodiversity, with differences over time and between biomes and latitudes .' 'Models are currently useful for developing scenarios of directional changes in net primary productivity, species distributions, community structure, and trophic dynamics of marine ecosystems, as well as their implications for ecosystem goods and services under climate change. However, specific quantitative projections by these models remain imprecise .'
