Climate change and concurrent demands on available resources are exerting unprecedented pressures on natural and managed ecosystems and may alter key landscape and atmosphere aspects, such as water and energy cycles and water quality. Under these changes, natural ecosystems may adapt or collapse, e.g. via shifts in species composition and resource use patterns through time, whereas managed ecosystems are altered by human-imposed land use change and management at different spatial and temporal scales. In turn, ecosystem functioning and adaptation have an effect on the ecosystem environment, e.g., via changes in soil properties or available resources, and water, nutrient and energy cycles. These changes may lead to feedbacks and potentially co-evolution of ecosystems, society, soils, climate, and the related ecosystem services, with potentially serious consequences for the resilience of social-ecological systems. These interactions between ecosystems and external forcings are often complex and may trigger non-linear regime shifts, thus affecting the stability of the ecosystems. However, in many studies these factors are investigated in isolation. In this session, we welcome submissions investigating the dynamics and feedbacks between natural or managed ecosystems, socio-economic pressures, environmental conditions, and climate; exploring ecosystem and societal responses to changing boundary conditions and their underlying principles; or providing new ideas or techniques on how such integrated ecohydrological systems can be analyzed and modelled, at scales ranging from the field to landscape up to the global scale. Of particular interest are studies with significant implications for management and socio ecological resilience and optimality.

Invited speaker: Iain Colin Prentice, with the talk "Acclimation of photosynthesis is not the icing on the cake. It is the cake."
