Ecosystem services provided by the Florida Keys marine ecosystem.

<p>The last column identifies these services as benefits, final or intermediate ecosystem services according to Fisher et al. 2009 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0070766#pone.0070766-Fisher1" target="_blank">[54]</a>.</p

The Florida Keys and Dry Tortugas EBM-DPSER model.

<p>The EBM-DPSER model for the Florida Keys and Dry Tortugas marine ecosystem identifies the key components of each module within the CEM.</p

Three common definitions of ecosystem services show significant disparity.

<p>The first row shows that the Millenium Ecosystem Assessment applies the broadest definition of ecosystem services with more detailed definitions provided by Boyd and Banzhaf <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0070766#pone.0070766-Boyd1" target="_blank">[53]</a> and Fisher et al <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0070766#pone.0070766-Fisher1" target="_blank">[54]</a>. In our initial EBM-DPSER model development we employed the MEA (2005) definition, because this was the most familiar definiton to the majority of participants and our goal was to build consensus. However, when the EBM-DPSER model is applied to conduct trade-off analyses of management options the other definitions for ecosystem services may be more appropriate. To help facilitate the application of other ecosystem service definitions, the table shows the linkages between the definitions of <i>ecosystem attributes people care about</i>, ecosystem services, and benefits used in this study, the Millenium Ecosystem Assessment, Boyd and Banzhaf 2007, and Fisher et al. 2009.</p

The south Florida water column sub-model.

<p>The sub-model for the water column of south Florida depicts the linkage from pressures (yellow ovals) to the state attributes that we measure (red boxes) with yellow arrows. These state attributes that we measure are organized into indicators for the water column (black outlined boxes and black text). The other states that influence the water column are depicted in the blue boxes and arrows to the right. The state attributes that we measure produce <i>ecosystem attributes people care about</i> (green boxes and arrows), which can be directly translated to ecosystem services.</p

The DPSIR model.

<p>This is the DPSIR conceptual model that has conventionally been utilized for ecosystem management, assessment, indicator selection, and communication.</p

The EBM-DPSER model.

<p>The DPSIR model was modified by replacing the impacts module with ecosystem services facilitating a more complete representation of ecosystem interactions including those with human society and the associated feedbacks. Ecosystem services are at the top of the model, instead of drivers to focus attention upon the module that should be the focus of EBM decision-making.</p
