title: Data from: The relevance of ecological status to ecosystem functions and services in a large boreal lake

description: 1. Environmental conventions aim to protect ecosystem structures and
 functions to provide goods and services for mankind. The degree of aquatic
 ecosystem naturalness, or ecological status as it is defined in the Water
 Framework Directive (WFD) of the European Union, is notionally linked to
 supplies of ecosystem services. In practice these links have rarely been
 documented or even investigated and, to justify conservation and
 management objectives based on the status indicators, it is essential to
 demonstrate their relationships to ecosystem functions and services. 2.
 The WFD requires member states to classify their surface waters aiming to
 achieve good ecological status of water bodies. However, an implicit
 assumption of the WFD, that the ecosystem functions and services targeted
 to be protected and maintained are related to the measured status, remains
 uncertain. 3. Using a time-series dataset covering almost 50 years, we
 examined the development of ecological status of eight sub-basins of a
 large boreal lake in response to improved wastewater management and
 decreasing pollution. We particularly evaluated whether the observed
 descriptors of biodiversity, ecosystem functions and services were
 associated with the judgements of ecological status, and hence if the
 ecological status is a relevant proxy for ecosystem values to be
 protected. 4. The ecological status of the polluted sub-basins responded
 consistently to the decreased nutrient and organic loading. Temporal
 trends in the biological quality elements and water quality were mostly
 parallel and showed good status roughly simultaneously. Combined
 ecological status also appeared to predict some features of taxon
 diversity (profundal macroinvertebrate and phytoplankton richness),
 ecosystem functions (primary and bacterial production) and ecosystem
 services (fish catch and reproductive potential of coregonids). 5.
 Synthesis and applications. We observed that some ecosystem service
 supplies and taxon diversity increased with increasing ecological status
 of the lake. Therefore, our results suggest that ecological status
 estimates based on simple structural characters are relevant to the
 ultimate management goals of maintaining biodiversity, ecosystem functions
 and services, and hence might suffice for extensive assessment and
 monitoring of lake ecosystems.
