Data Issues Point data: Species, locality, date, source Species issues: identification, synonyms, life stage, size Locality issues: errors, no coordinates, too broad descriptors, depth missing Date issues: missing, or year only, time wanted Source issues: credit, reliabilty indicator Environmental data: few aquatic datasets

Researchable Questions Niche circumscription Prediction of occurrence: –native range (niche distribution, co- occurrence, seasonal distribution, H-Map) –invasive range (vectors, algal blooms,..) –global change scenarios (F-Map) Outlook –Abundance modelling >> >>>> –Reverse prediction

Discussion Is it not time for oceanographers to link up with marine biologists?
