Fig. 4: Crab burrowing enhances greenhouse gas production.
From: Widespread crab burrows enhance greenhouse gas emissions from coastal blue carbon ecosystems

The violin plots compare emission rates of (a) CO2, (b) CH4 and (c) N2O in burrows and matrix. The cumulative bar charts integrate greenhouse gas fluxes (d CO2; e CH4; f N2O) in burrows versus matrix during the 28-day incubation period. The box plots indicate the range in cumulative fluxes for different sampling sites. The red font indicates the multiple of mean value of emission rates or fluxes in burrow versus matrix. The “**” and “*” indicate the significance levels at p < 0.01 and p < 0.05, respectively.
