Pigmented skin tumors in gizzard shad (Dorosoma cepedianum) from the south-central United States: Range extension and further etiological studies

Climate change is having a significant effect on many allergenic plants resulting in increased pollen production and shifts in plant phenology. Although these effects have been well-studied in some areas of the world, few studies have focused on long-term changes in allergenic pollen in the South Central United States. This study examined airborne pollen, temperature, and precipitation in Tulsa, Oklahoma over 25 to 34 years. Pollen was monitored with a Hirst-type spore trap on the roof of a building at the University of Tulsa and meteorology data were obtained from the National Weather Service. Changes in total pollen intensity were examined along with detailed analyses of the eight most abundant pollen types in the Tulsa atmosphere. In addition to pollen intensity, changes in pollen season start date, end date, peak date and season duration were also analyzed. Results show a trend to increasing temperatures with a significant increase in annual maximum temperature. There was a non-significant trend toward increasing total pollen and a significant increase in tree pollen over time. Several individual taxa showed significant increases in pollen intensity over the study period including spring Cupressaceae and Quercus pollen, while Ambrosia pollen showed a significant decrease. Data from the current study also indicated that the pollen season started earlier for spring pollinating trees and Poaceae. Significant correlations with preseason temperature may explain the earlier pollen season start dates along with a trend toward increasing March temperatures. More research is needed to understand the global impact of climate change on allergenic species, especially from other regions that have not been studied.

Pine Stands

Abstract Commercial harvests were carried out on 36% of the pine-site timberland in six states of the south-central United States during the interval of time between the last two forest inventories of each state. Half of forest industry's pine-site timberland was harvested, compared with 30% for nonindustrial private owners. Fifty-four percent of the heavily cut pine stands were at least 60% stocked with pine following harvest. The overall rate of replacement for pine stands was 78%. South. J. Appl. For. 14(2):59-63.
