Another recent study did research in Bolivia to study the pollen assemblage in high altitude soils, this study also created a forensic database for uses in non-seasonal soil. [14] This database creation is allowing forensic palynology to be used in a more broad area now, as data for both high altitude pollen assemblage and non-seasonal soil ...
The methodology of pollen analysis became widespread throughout Europe and North America and revolutionized Quaternary vegetation and climate change research. [13] [15] Earlier pollen researchers include Früh (1885), [16] who enumerated many common tree pollen types, and a considerable number of spores and herb pollen grains.
A pollen core is a core sample of a medium containing a stratigraphic sequence of pollen. Analysis of the type and frequency of the pollen in each layer is used to study changes in climate or land use using regional vegetation as a proxy. [1] [2] This analysis is conceptually comparable to the study of ice cores.
Metabarcoding is the process of identifying the individual species DNA from a mixed DNA sample and is commonly used to catalog pollen in mixed pollen loads found on pollinating animals and in environmental DNA (also called eDNA) which is DNA extracted straight from the environment such as in soil or water samples.

However, the use of a pollen calendar to set the date of death should be used with extreme caution, and only by a carefully trained expert witness. [7] The CSI effect has put pressure on some police officers and district attorneys to provide pollen-based evidence , but such evidence "appear[s] to be of limited use in the forensic context where ...
Pollen Analysis Could Provide Missing Link in 40-Year-Old Cold Case. In 1976, a woman's body was found near a cemetery in Baltimore County, Maryland –– wrapped in a sheet with her hands bound ...
pollen profile pollen spectrum A series of side-by-side graphs, produced by archaeobotanists and palynologists, showing the frequency of different types (species) of pollen in a soil sample by depth. Usually presented vertically, with the shallowest samples at the top and the deepest at the bottom, to represent a pollen core or other stratified ...
Pollen is another ecofact found at archaeology sites where Palynology which is the study of pollen/dust can be used to reveal information about the site environment, the identity of plants used and also be used to reveal whether plants were wild or domesticated.
