Abstract Intensive management of larch in the north central and northeastern United States is receiving considerable interest because of the rapid growth of European and Japanese larch and the hybrids between these two species. A needlecast disease caused by the fungus Mycosphaerella laricina has the potential to reduce tree growth and kill highly susceptible trees. Research in Wisconsin and Iowa using six larch species and hybrids has provided data showing the importance of seed source selection in minimizing damage caused by this disease. North. J. Appl. For. 6:172-174, December 1989.

Algal chlorophyll a is commonly used as a surrogate for algal biomass. Data from three lakes in western Nebraska, five wetlands in north-central North Dakota, and two lakes in north-central Minnesota represented a range in algal biovolume of over four orders of magnitude and a range in chlorophyll a from less than 1 to 380 mg∙m−3. Analysis of these data revealed that there was a linear relation, log10 algal biovolume = 5.99 + 0.09 chlorophyll a (r2 = 0.72), for cases in which median values of chlorophyll a for open-water periods were less than 20 mg∙m−3. There was no linear relation in cases in which median chlorophyll a concentrations were larger than 20 mg∙m−3 for open-water periods, an occurrence found only in shallow prairies lakes and wetlands for years in which light penetration was the least.
