The Arctic Holocene Biodiversity Database (AHBD) is an evolving metadata database of time-series biodiversity metrics covering the last 11,750 years in the Arctic region. The database is currently being constructed as the output of a systematic map (see the published protocol at the below link); new data is being added on a monthly basis. On the associated mapping interface, the AHBD has been connected to a cryosphere database arising from the CHELSA model. Use the 'slicers' underneath the map to explore by cryospheric overlap. To be included in the map (although for full details see the protocol) a source of information must: (a) include biota that we are targeting; (b) fall within the Arctic area (Arctic Biodiversity Assessment areas and CAFF region); (c) contain two or more years in time-series; and (d) consist of a biodiversity measure.
