Abstract [en]

Understanding large-scale spatial variation in ecosystem properties and associated functionality is key for successful conservation of ecosystems. This study provides a template for how to estimate differences in ecosystem functionality over large spatial scales by using groupings of biological traits. We focus on trait groupings that describe three important benthic ecosystem properties, namely bioturbation, community stability, and juvenile dispersal. Recognizing that groups of traits interact and are constrained within an organism, we statistically define important functional trait sub-groups that describe each ecosystem property.The sub-groups are scored according to their weighted ecological impact to gain an overallestimation of the cumulative expression of each ecosystem property at individual sites. Furthermore, by assigning each property a value relative to its observed maximum, and by summing up the individual property values, we offer an estimate of benthic ecosystem multi-functionality. Based on a spatially extensive benthic data set, we were able to identify coastalareas with high and low potential for the considered benthic ecosystem properties and the mea-sure of ecosystem multifunctionality. Importantly, we show that a large part of the spatial vari-ation in functional trait sub-groups and in benthic ecosystem multifunctionality was explainedby environmental change. Our results indicate that through this simplification it is possible toestimate the functionality of the seafloor. Such information is vital in marine spatial planningefforts striving to balance the utilization with the preservation of natural resources.
