In marine environments, macrofauna living in or on the sediment surface
may alter the structure, diversity and function of benthic microbial
communities. In particular, microbial nitrogen (N)-cycling processes may
be enhanced by the activity of large bioturbating organisms. Here, we
study the effect of the burrowing mud shrimp Upogebia deltaura upon
temporal variation in the abundance of genes representing key N-cycling
functional guilds. The abundance of bacterial genes representing different
N-cycling guilds displayed different temporal patterns in burrow sediments
in comparison with surface sediments, suggesting that the burrow provides
a unique environment where bacterial gene abundances are influenced
directly by macrofaunal activity. In contrast, the abundances of archaeal
ammonia oxidizers varied temporally but were not affected by bioturbation,
indicating differential responses between bacterial and archaeal ammonia
oxidizers to environmental physicochemical controls. This study highlights
the importance of bioturbation as a control over temporal variation in
nitrogen-cycling microbial community dynamics within coastal sediments.
