1 Ecospace Beth Fulton 2012

2 Builds on Ecopath and Ecosim Spatial version Regular grid ECOSIM on each cell movement along gradients across cell (weighted by preferred habit) Once defined go to Run Ecospace and press Run output is spatial distribution of groups through time and overall Ecosim result ECOPATH, ECOSIM and ECOSPACE Ecospace

3 Replicates Ecosim dynamics in each cell Links cells through dispersal of organisms and effort allocation (and advection option) ECOPATH, ECOSIM and ECOSPACE Ecospace B ij Equal ms (symmetrical mixing, except at shores or when toward preferred habitats) Equal ms (symmetrical mixing, except at shores or when toward preferred habitats) m i,j+1 B ij

4 Basemap (can be from GIS) define rows and columns select habitat type and draw it on draw on protected zones define areas of differing relative primary productivity all done by selecting different option on sheet and then drawing in shape with cursor loading GIS maps gets easier ECOPATH, ECOSIM and ECOSPACE Ecospace

5 Basemap (can be from GIS) Ecospace

6 Habitats – define by clinking on habitats icon Represents habitat preferences by differential dispersal, feeding and predation rates Ecospace - Habitats

7 ECOPATH, ECOSIM and ECOSPACE Association of groups to habitats identify habitats fisheries can access ECOPATH, ECOSIM and ECOSPACE Ecospace - Habitats

8 Accounts for spatial variation in productivity and cost of fishing (paint or load) Ecospace - Map

9 Ecospace - Advection Advection = slab hydrodynamic flows (per month) load or draw on wind, upwelling, MLD and Calculate

10 Include dispersal Ecospace - Movement

11 Migration centre point specified per month per species Ecospace - Migration

12 Once defined go to Run Ecospace and press Run output is spatial distribution of groups through time and overall Ecosim result Ecospace - Run

13 Ecoseed = spatial optimisation of MPA size & location ECOPATH, ECOSIM and ECOSPACE Ecospace – Extras Evaluates one seed cell for each run Best seed cell is selected as an MPA cell Adjacent cells become seed cells Process continues until all cells are MPAs

14 Marine protected area effects Ecospace - Example
