SBC LTER : REEF: Ammonium excretion rates of macroinvertebrates

Consumers may be important mediators of nutrient cycling in giant
kelp forests. To aid in this assessment, we measured the ammonium
excretion rates of 17 species of macroinvertebrates which comprise
85-97% of the biomass among reefs surveyed by the LTER in the Santa
Barbara Channel. We paired these species-specific data with time
series of their standing biomass to assess their contributions to
kelp forest nitrogen recycling and to examine patterns in their
nutrient dynamics over annual and decadal scales. This is the data package supporting the article “Peters, JR, Reed,
DC, Burkepile, DE. Climate and fishing drive regime shifts in
consumer‐mediated nutrient cycling in kelp forests. Glob Change
Biol. 2019; 25: 3179– 3192. https://doi.org/10.1111/gcb.14706”.
