Frequency and abundance of pollen taxa in crime case samples from the United Kingdom

摘要: The frequency and abundance of pollen taxa in samples from crime cases which forensic palynology had been employed, was investigated by collating pre-existing data. Fifteen England Northern Ireland that represented a range habitats exhibit types were selected total 199 included the analysis. Control considered separately to those exhibits. latter contained wider more likely contain planted ornamentals such as Cedrus, Ligustrum, Juglans Platanus. Pollen Poaceae family occurred 100% greatest mean (25.65%) wind-pollinated Pinus, Betula, Quercus, Alnus, Fraxinus, Corylus Urticaceae also with very high (> 80%). Most < 6% but several higher. Maximum was studied, varying greatly some taxa, notably Castanea sativa, Plantago lanceolata-type, Pteridium aquilinum Quercus. Not all frequently wind-pollinated: members insect-pollinated families Apiaceae, Asteraceae, Brassicaceae, Ericaceae Rosaceae, well Hedera helix Sambucus, quite found, sometimes relatively maximum abundance. results demonstrate certain plants repeatedly occur both control samples. This information can assist evaluation profiles cases.
