Abstract

In order to obtain a perspective of the distribution of benthic foraminifera across the globe, we present the first comprehensive data compilation on living foraminifera from coastal lagoons. Benthic foraminifera are an important bioindicator of water and sediment conditions group, but there is a relative scarcity of studies in coastal lagoons about this group. Our literature search (following the PRISMA methodology) retrieved 1,380 peer-review publications, of which 902 came from the Web of Science database and 478 from Scopus. We removed the duplicates (n = 469) and with the remaining 911 manuscripts we applied the exclusion criteria filters to get our final database composed of 49 studies used for this review. We recorded a total of 458 benthic species distributed in 17 countries. Our results reveal the existence of studies not homogeneously distributed in coastal lagoons around the globe (Wallacean shortfall) that limit in-depth understanding of the biogeography of this important bioindicator group, directly reflecting on another's knowledge gaps: the Linnean Shortfall (gap of species), Hutchinsonian shortfall (gap of abiotic tolerances) and Prestonian Shortfall (gap of populations dynamics).
