Preston et al. 2025 Supplementary Table: Marine Temperate Habitat connectivity evidence from structured review

A structured literature review was carried out during 2022/23 to create this database on the published evidence of connectivity across the temperate seascape. The initial literature search was conducted through Web of Science (WoS) (01/11/2022) using the following search terms: <i>(connectivity OR seascape* OR meta-ecosystem* OR habitat-mosaic* OR mosaic-habitat* OR (habitat AND mosaic*)) AND (coastal OR marine OR estuar* OR ocean*) AND (((saltmarsh* OR (tidal AND marsh*)) AND (seagrass* OR macroalga* OR seaweed* OR macrophyte* OR kelp* OR oyster* OR mudflat* OR ((tidal OR intertidal) AND flat*))) OR (seagrass* AND (saltmarsh* OR (tidal AND marsh*) OR macroalga* OR seaweed* OR macrophyte* OR kelp* OR oyster* OR mudflat* OR ((tidal OR intertidal) AND flat*)))), seagrass* AND ( saltmarsh* OR marsh* ) AND nutr* AND nitr* AND phosph*AND temperate. </i>This resulted in 187 papers, including 15 reviews. Cross referenced papers were subsequently explored and added to the database of 215 peer reviewed publications (09/12/2022). Publications were categorised manually by type (see Collins et al., (2015); flows (physical, carbon, nutrient, biodiversity), location (distinct location and biogeographic region), habitats included (seagrass, saltmarsh, oyster reef, coral reef, mangrove, unvegetated sediment, seaweed/rock, rhodolith, beach/dune, offshore, terrestrial), taxonomic focus, conservation focus, generation of empirical data, use of numerical model, cultural ecosystem service focus. Biogeographic region was assigned using the Marine Ecosystems of the World (MEOW), (Spalding et al., 2007) which consists of 12 realms (Arctic; Temperate Northern Atlantic; Temperate Northern Pacific; Tropical Atlantic; Western Indo-Pacific; Central Indo-Pacific; Eastern Indo-Pacific; Tropical Eastern Pacific; Temperate South America; Temperate Southern Africa; Temperate Australasia; Southern Ocean) and nested 62 provinces. Each paper in this database was assigned a value determined by the relevance multiplied by robustness. This value was used to prioritise focus on relevant papers, to identify areas of evidence gaps (Collins et al., 2015) and identify problems with the search terms. In addition, expert knowledge was used to add scientific papers not identified in WoS or covered by the search terms to the database, via the outputs from the workshop and during the writing of the manuscript Preston et al. (2025). This database contains a total of 304 publications.<br>References:Collins, A., Coughlin, D., Miller, J. &amp; Kirk, S.
