The vegetation in different strata shows varying evaporation rates. In vegetation averaging five feet tall, the evaporation rates at the top, middle, and bottom were 100:32.8:6.6. In two-foot vegetation, the ratios were 100:56.2:14.7. These ratios indicate humidity levels within and on the vegetation. Temperature variations showed that upper layers experienced greater temperature fluctuations than upper air or lower vegetation layers. Since plant species vary in height, few marsh plants face identical conditions, allowing xerophytic and non-xerophytic plants to coexist in different conditions. Catalase's role in aerobic vs. anaerobic respiration was studied. Rosenberg found catalase abundant in seeds with high aerobic respiration. In yeast, catalase decreased with fermentation, while in seeds, it increased with germination. Acids and salts reduced catalase activity, while certain phosphates increased it. Rosenberg concluded catalase is aerobic. However, critics noted that acids destroy catalase and were not considered in her methods, possibly leading to inaccurate results. Her conclusion was too broad based on limited data. Pearson described Welwitschia embryo development. The embryo starts as a group of cells at the suspensor tip, forming a meristematic group similar to Ginkgo. The suspensor thickens from root cap cells. Embryo development finishes before seed release, taking about four months. Some 1907 seeds germinated in 1910. Crocker's 1911 study on catalase was published in Botanical Gazette. The Biodiversity Heritage Library provides access to this work, noting it is in the public domain. The study is part of the Missouri Botanical Garden's collection.The vegetation in different strata shows varying evaporation rates.
