“…Scanning electron microscope stubs were made after the soil sample was acetolysed prior to staining the sample. They found significantly more pollen types with SEM than LM; 20 new taxa were found after nearly 2000 pollen grains were counted (Jones & Bryant, 2007). During the SEM analyses of their research, several types of Tilia pollen grains were differentiated with SEM but not with LM (Jones & Bryant, 2007).…”

During the SEM analyses of their research, several types of Tilia pollen grains were differentiated with SEM but not with LM (Jones & Bryant, 2007). After seeing the differences in Tilia pollen grains with SEM, they went back and examined the LM analyses and found that those differences could be seen with LM.…”

“…Debris is something that all palynologists work around. Separation of pollen from debris in LM depends on the concentration of the pollen residue, the ionic concentration, the mounting media and the amount of the drop that is put onto the slide (Jones & Bryant, 2007). With LM, pollen grains are more easily separated from debris because the pollen grains can be rolled away from the debris (depending on the mounting media).…”

“…Pollen grains were identified to the lowest nomenclatural rank possible, family, genus, or species. Pollen from the Asteraceae (sunflower family) was divided into LS for grains with short processes or HS for grains with long processes (Jones & Bryant, 2007;Martin, 1963). The USDA-ARS APMRU, Stanley D. and Gretchen D. Jones, David and Susan Jarzen, and Meredith Lieux pollen reference collections were used to help in the identification processes.…”

Pollen contamination of boll weevil traps

The boll weevil, Anthonomus grandis Boheman, has been the most devastating insect pest of cotton, Gossypium hirsutum L., in the southern United States of America (USA). Although thought to feed only on cotton, the list of non-cotton alternative food sources increases yearly. Many of these taxa are thought to be contaminates and not food sources. The purpose of this research was to examine the possibility that weevils become contaminated with pollen while sitting in the trap. Between January and April, boll weevil traps were placed near Brownsville and Weslaco (a substitute location) and in Santa Ana Wildlife Refuge, Texas. Pollen was removed from the trap's pole, skirt, mesh cone, and lid by wiping them with an individual, sterile, 100% cellulose acetate filter. The original trap was replaced with a replacement trap that was left for three days, then wiped for pollen. Little pollen was found on the trap parts regardless of the month or the site. The mesh cone was the least contaminated. From these data, it is doubtful that weevils become contaminated with pollen while sitting in the trap. Additional research is needed to examine if pollen is transferred among trapped weevils.

Pollen and Spore Evidence in Forensics

Forensic palynology, the use of pollen and spores to assist in solving criminal and civil cases, is a highly underutilized and neglected technique. During the past century, there have been only limited attempts to use pollen and spore evidence in either criminal or civil cases for a variety of reasons, including a lack of available information about the technique, a very limited number of specialists trained to do this type of forensic work, and an almost total absence of academic centers that are capable of training needed pollen specialists or forensic facilities able, or willing, to fund research in this area. I outline examples of how forensic pollen has been used as evidence and how it has proved helpful in finding and convicting criminals guilty of various types of crimes. I also explore new areas and analytical techniques being offered to enhance the precision of pollen data. The reliability and increased use of forensic palynology can change provided steps are taken to encourage better research and data and routine collection, analysis, and use of pollen evidence in both criminal and civil cases.
