The leaf I chose to represent phytophagy on campus displayed more characteristics for evidence than others I examined. The exact location of this leaf was 1 foot away from a nearby tree across from Recreational center. I was intentionally searching for fallen leaves, as I predicted they would be easier for insects to eat without having to expend much energy climbing a tree.
The leaf exhibits a dark green color. I predicted the leaf had recently fallen, due to its stiff texture. On the leaf there are various sized holes. The smallest was only some millimeters long while the largest had been approximately 2/10ths of a centimeter. Around the holes are small bumps which are discolored. They are lighter in color than the lear’s entirety, with hints of brown. This does not look like a typical display of leaf decay, so it is highly likely that those areas are where phytophagy occurred. I kept the sample with me in the case it is needed in the future.
Plasma cell dyscrasias is discussed in this article through the analysis of multiple myeloma. Multiple myeloma is a cancer of the plasma cells but of a certain type. When plasma cells begin to grow abnormally, they make a certain type of antibody and form a monoclonal paraprotein. They can be detected in the bone marrow and other tissues. The premalignant stage of multiple myeloma is characterized by the presence of the abnormal antibody, monoclonal gammopathy of undetermined significance (MGUS). This antibody is present in 3-4% of normal individuals over the age of 50 years old and is only an issue if it progresses to multiple myeloma. The risk of MGUS progression to multiple myeloma increases by 10% in the first 5 years after diagnosis MGUS could also develop into a different plasma cell disorder as it is still an abnormal protein. This development could lead to disorders such as plasma cell leukemia or Waldenstrom macroglobulinemia.
