Conceptual Model: Consumer Dynamics & Food Webs

Consumer Dynamics and Food Webs

Warming temperatures and rising sea level are expected to lead to changes in PIE food webs.  We anticipate changes in
     - species distribution across the system, and
     - abundances of some species, including
     - range expansions by southern species, leading to
     - alternate food web structures, and
     - increased energy flow to marine pathways,

resulting from
     - changing salinity regimes with sea-level rise and as freshwater flow from the watershed changes
     - restructuring of habitats and resourse access as the shape of the marsh changes
     - changes in organic matter production, and

    - species immigration and emigration.
