Deliverable 3.3

Influence of temperature change on key ecological, functional and biodiversity responses of lakes in recovery after nutrient reduction and in-lake restoration measures Abstract: Planet Earth has entered a new epoch, the Anthropocene, that is characterized by rapid environmental change (Crutzen 2002). Changing environmental conditions not only alter ecological, but also social baselines, and eventually the interaction between social and ecological systems (Berkes et al. 2003). Past human pressures on the environment have motivated management and restoration approaches to counteract the negative effects of, for instance, eutrophication or acidification. Large amounts of taxpayer’s money have been allocated to restoration and mitigation interventions. However, it is unclear how further changes in environmental conditions, often comprising complex interaction between multiples stressors (e.g. increasing temperatures, species invasions, altered landuse patterns) will influence management success in the future. The aim of this deliverable is to outline current trends of scientific research that link climate change aspects with key ecological structural and functional aspects in ecosystems under recovery from nutrient reduction and in-lake restoration measures.

The key take home messages from this deliverable are that:

  1. There is a critical need to understand landscape scale patterns, including land use aspects and hydrological connectivity, when assessing ecological responses to climate change in ecosystems under recovery.
  2. While a trait-based approach will improve our understanding of community structural and functional responses to certain stressors, the broader ecosystemic responses to rapid environmental change will be context dependent, complicating the broader assessment of ecosystem vulnerabilities to change and resilience.
