With this initiative BioFresh brings together species records data of macroinvertebrate from global Mediterranean climate rivers (Mediterranean Basin, South Africa, Chile, California, and Australia). Mediterranean climate regions are of special interest to BioFresh because they constitute top biodiversity hotspots of the world, despite occupying only 1.2% of land surface. Rivers in these regions host a high and endemic biodiversity, and are considered unique freshwater ecosystems. However, the knowledge regarding freshwater biodiversity remains scattered and incomplete. Available information on already existing datasets, published papers, and grey literature (thesis, reports, etc.) has been brought together into the Global Mediterranean Macroinvertebrate Database (MacroMED).
This database contains 29,100 geo-referenced species records from 3,220 sites scattered throughout the global Mediterranean climate regions, and information on 1,473 species/subspecies. Species records are expected to increase when this database is crossed with other macroinvertebrate contingency fund projects that include Mediterranean climate areas, such as DAET (Trichoptera) and DAEP (Plecoptera) projects. All this data is being integrated into the BioFresh portal.
