Mangroves and salt marshes are among the most productive ecosystems in the global
coastal ocean. Mangroves store more carbon (739 Mg CORG ha− 1) than salt marshes (334 …

Abstract Background Marine macroalgae ('seaweeds') are a diverse and globally distributed
group of photosynthetic organisms that together generate considerable primary productivity …

Global seaweed carbon sequestration estimates are currently taken as the fraction of the net
primary production (NPP) exported to the deep ocean. However, this perspective does not …

Foundation species define the ecosystems they live in, but ecologists have often
characterized dominant plants as foundational without supporting evidence. Giant kelp has …

Climate models predict a dramatic increase in the annual frequency and severity of extreme
weather events during the next century. Here we show that increases in the annual …

We combine data collected from the past 40 years to estimate the indirect effects of sea
otters (Enhydra lutris) on ecosystem carbon (C) production and storage across their North …

Kelp forests are known as key habitats for species diversity and macroalgal productivity;
however, we know little about how these biogenic habitats interact with seawater chemistry …

Rates and drivers of primary productivity are well understood for many terrestrial
ecosystems, but remain poorly resolved for many marine ecosystems, particularly those …

Recently, Gallagher et al. suggested that seaweed ecosystems are net heterotrophic carbon
sources due to CO2 released from the consumption of external subsidies. Here we outline …

We took advantage of regional differences in environmental forcing and consumer
abundance to examine the relative importance of nutrient availability (bottom‐up), grazing …
