Ecosystem Ecology : A New Synthesis
A variety of spatially explicit models or tools have been used for watershed-scale studies of environmental indicators and ecosystem services. Examples include Artificial Intelligence for Ecosystem Services (ARIES) (Villa et al. 2009), Multiscale Integrated Models of Ecosystem Services (MIMES) (Boumans et al. 2015), and Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) (Tallis and Polasky 2009, Bagstad et al. 2013b, Tallis et al. 2013). These models do not capture seasonal or subseasonal climate variability, which is projected to change regionally (Wood et al. 2002, Hayhoe et al. 2007, Horton et al. 2014) and is important for capturing watershed functions related to flood attenuation, water provisioning, river temperature regulation, and other ecosystem services (Vigerstol and Aukema 2011). To fully account for changes in ecosystem function associated with altered precipitation, temperature, and land-use and land-cover patterns, process-based models that incorporate key space- and time-varying hydrological and ecological processes are critical (Bagstad et al. 2013b).

Today, worldwide interest in ecosystems ecology has resurged, as shown by its prominence in publications and university curricula, initiatives such as the , and new journals such as and .
Not every forest ecosystem service (ecological or commercial) can be provided on every acre. To ensure long-term ecosystem functions, a mosaic of levels and types of management, protection, and human-use is necessary. This project provides insights to assist in sustainability of landscape-level functions through management, policy, and sustainable practices. Researchers are investigating biodiversity (emphasis on birds) and ecosystem functions (emphasis on carbon sequestration and watershed ecosystem services) on an urban to wildland gradient. Social components of land management include urban forestry, silviculture and forest management, and land conservation and stewardship.
The Economics of Ecosystems and Biodiversity - TEEB
We present an approach that links time-varying (daily time-step) terrestrial and aquatic ecosystem models at regional scales and apply this model into the future using scenarios of climate and land cover to project changes in ecosystem services. First, we describe an indicator framework that succinctly represents a comprehensive suite of environmental conditions relevant to important ecosystem services. Second, we describe the linkage and validation of the terrestrial and aquatic ecosystem models to simulate aquatic indicators through the 21st century. We integrated the Photosynthetic Evapotranspiration-Carbon and Nitrogen (PnET-CN) forest ecosystem model (Ollinger et al. 2002, 2008, Aber et al. 2005) and the Framework for the Aquatic Modeling of the Earth System (FrAMES) aquatic ecosystem model (Wollheim et al. 2008a, b, Wisser et al. 2010, Stewart et al. 2011, 2013, Mineau et al. 2015; Zuidema, Wollheim, Mineau, et al., unpublished manuscript). These models integrate the dynamics of terrestrial and aquatic processes and linkages at daily time-steps, making them ideal for studying aquatic ecosystem responses in forest-dominated watersheds. In coordination with a separate effort described elsewhere in this special issue (Mavrommati et al. 2017) to assess the value of ecosystem services provided by the Upper Merrimack River watershed (UMRW) of New Hampshire, we contrast two extremes of projected futures in climate and land-cover change. The outcome suggests that climate change influences most indicators of environmental condition in the UMRW more than changes in land cover, although land cover has important interactive capacity to dampen or exacerbate the effects of the changing supply of ecosystem services in the future.

There are many implications to the application of the “new ecology” of ecosystems and complex systems science to the study of human ecosystems.

Food production and sustainability, fresh water limits, global warming, deforestation, biodiversity loss are all complex human–environmental problems with linked biotic–physical components; ecosystems ecology is an obvious choice for their study.
