Benthic epifauna in three areas of the northern North Sea was studied from 1999 to 2007 to investigate the effect of temperature
changes on community structure and species abundance and biomass. Abundance and/or biomass of 16 epifauna species was significantly
correlated with temperature anomalies of the mean sea surface temperature (SST) from 1971 to 2000. The response of species
to SST changes was different in the study areas depending on species life history and, most likely on food supply, which in
turn is strongly influenced by the timing and duration of primary production and regional hydrographical conditions (e.g.
stratification). Also, changes in community structure were obvious in the three areas between 2002 and 2003 coinciding with
high temperature anomalies and SST. On the other hand, these changes were mainly caused by the variability in abundance of
dominant species and altogether no clear trends in community structure were found. In contrast to epifauna communities in
the shallow southern North Sea temperature changes in the northern North Sea affected only single epifauna species until now. 相似文献

SUMMARY Sustainable development is a global challenge to science and society. In politics and economics the concepts for establishing a sustainable society are numerous, nonetheless necessary interdisciplinary approaches are still marginalised. Trying to foster a deeper communication between biology and social science, an evolutionary perspective on sustainable development is offered. Subsequently, the role of variability and diversity in evolution is highlighted. Hereby, special attention is devoted, among other things, to the links between variability and stability in the long term. Next, selection and variability are emphasised in the cultural context. This is followed by general implications for sustainability. In contrast to strategies aiming at short-term optimisation and economic efficiency, we argue that the conditions and circumstances maintaining variability and momentary sub-optimal alternatives are highly relevant for a socio-economic system that is heading for sustainable development. 相似文献
