Declining biodiversity and loss of ecosystem function threatens the
ability of habitats to contribute ecosystem services. However, the form of
the relationship between biodiversity and ecosystem function (BEF) and how
relationships change with environmental change is poorly understood. This
limits our ability to predict the consequences of biodiversity loss on
ecosystem function, particularly in real-world marine ecosystems that are
species rich, and where multiple ecosystem functions are represented by
multiple indicators. We investigated spatial variation in BEF
relationships across a 300 000 m2 intertidal sandflat by nesting
experimental manipulations of sediment pore water nitrogen concentration
into sites with contrasting macrobenthic community composition. Our
results highlight the significance of many different elements of
biodiversity associated with environmental characteristics, community
structure, functional diversity, ecological traits or particular species
(ecosystem engineers) to important functions of coastal marine sediments
(benthic oxygen consumption, ammonium pore water concentrations and flux
across the sediment–water interface). Using the BEF relationships
developed from our experiment, we demonstrate patchiness across a
landscape in functional performance and the potential for changes in the
location of functional hot and cold spots with increasing nutrient loading
that have important implications for mapping and predicating change in
functionality and the concomitant delivery of ecosystem services.
