GRANA publishes original papers in palynology and aerobiology.
Palynological research interacts with a wide diversity of scientific disciplines, providing data that can be used to interpret basic biological processes through to environmental changes over much larger timescales. As a result, GRANA caters for a diverse audience, publishing across the breadth of palynological research, including melissopalynology, quaternary palynology and vegetation history, pollen morphology, pollen development, palaeopalynology and aerobiology.
Palynology includes studies on morphology and ultrastructure of pollen grains and spores of Eucaryota and their importance for plant taxonomy, phlyogeny, ecology, phytogeography, palaeobotany, etc.; studies on dispersed grains investigate their systematic and stratigraphic significance.
Aerobiology involves studies of airborne biological particles such as pollen spores, etc., and their launching, dispersal and final deposition. The significance of these particles in medicine (allergology) and plant pathology is of particular interest.
GRANA also publishes palaeobotanical and palaeopalynological studies that primarily analyse the systematics and phylogeny of extinct reproductive structures with in situ spores and pollen.
Since 2007, GRANA has collaborated with the European Pollen Database (EPDB) by publishing short contributions in a standardised format at irregular intervals as documentation for pollen data delivered to the database.
