Map illustrating the location of the research study and number of published scientific studies in each temperate ecoregion identified as examining the evidence of connectivity between biogenic coastal habitats (full database is available, see data availability statement). Tropical and polar biogeographic regions are excluded from the analyses. The white and grey hatched area (0 studies) illustrates the substantial evidence gaps in this study across large biogeographic regions, particularly South America and Russia.
