A major challenge in ecology is to understand determinants of ecosystem functioning and stability in the face of disturbance. Some important species can strongly shape community structure and ecosystem functioning, but their impacts and interactions on ecosystem-level responses to disturbance are less well known. Shallow ponds provide a model system in which to study the effects of such species because some taxa mitigate transitions between alternative ecosystem states caused by eutrophication. We performed pond experiments to test how two foundation species (a macrophyte and a mussel) affected the biomass of planktonic primary producers and its stability in response to nutrient additions. Individually, each species reduced phytoplankton biomass and tended to increase rates of recovery from disturbance, but together the species reversed these effects, particularly with larger nutrient additions. This reversal was mediated by high cyanobacterial dominance of the community and a resulting loss of trait evenness. Effects of the foundation species on primary producer biomass were associated with effects on other ecosystem properties, including turbidity and dissolved oxygen. Our work highlights the important role of foundation species and their interactive effects in determining responses of ecosystem functioning to disturbance.

The debates about naming the unfolding times of anthropogenic global change the ‘Anthropocene’ are ultimately debates about the ‘human condition’. The proposal to amend the geological time scale by adding an ‘Anthropocene’ epoch (that is, the ‘Anthropocene proposal’ in its strict sense) is both an intra-geoscience debate about scientific sense-making and a debate about the societal context of the geosciences. This essay juxtaposes these debates, starting from three postulates: first, that the scientific methods of geological chronostratigraphy are applied rigorously; second, that anthropogenic global change is happening; and third, that the ‘Anthropocene proposal’ may be rejected if it does not meet the conditions required for its approval based on the rigorous application of the scientific methods of geological chronostratigraphy. These postulates are analysed through the lenses of the Cape Town Statement on Geoethics and the normative statements of the ‘geoethical promise’. It is found that an ethical quandary would arise if the ‘Anthropocene proposal’ were to be rejected. Consequently, and given the societal contexts of the geosciences, it is explored whether distinguishing between the geological past (as demarcated according to current chronostratigraphic methodology) and contemporary geological–historical times (characterised somewhat differently) could offer a work-around to tackle the quandary.
