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.
