Abstract (from ScienceDirect): Climate change is affecting the benefits society derives from forests. One such forest ecosystem service is maple syrup, which is primarily derived from Acer saccharum(sugar maple), currently an abundant and widespread tree species in eastern North America. Two climate sensitive components of sap affect syrup production: sugar content and sap flow. The sugar in maple sap derives from carbohydrate stores influenced by prior year growing season conditions. Sap flow is tied to freeze/thaw cycles during early spring. Predicting climate effects on syrup production thus requires integrating observations across scales and biological processes. We observed sap at 6 sugar maple stands spanning...

Downscaling is the process of making a coarse-scale global climate model into a finer resolution in order to capture some of the localized detail that the coarse global models cannot resolve. There are two general approaches of downscaling: dynamical and statistical. Within those, many dynamical models have been developed by different institutions, and there are a number of statistical algorithms that have been developed over the years. Many past studies have evaluated the performance of these two broad approaches of downscaling with respect to climate variables (e.g., temperature, precipitation), but few have translated these evaluations to ecological metrics that managers use to make decisions in planning for...

Maple syrup is produced from the sap of sugar maple trees collected in the late winter and early spring. Native American tribes have collected and boiled down sap for centuries, and the tapping of maple trees is a cultural touchstone for many people in the Northeast and Midwest. Overall demand for maple syrup has been rapidly rising as more people appreciate this natural sweetener. Yet because the tapping season is dependent on weather conditions, there is concern about the sustainability of maple sugaring as the region’s climate changes. The distribution of sugar maple could move north into Canada and the sap flow season may become shorter in the future. Not only could these changes affect producers and consumers...
