Data from Nature’s Notebook are bringing landscape change into focus in Alaska

Wed, Jan 15, 2014

Spring leaf-out phenology observations have proven valuable in predicting how arctic plant communities may change in coming decades. Models used to predict changes in plant communities have traditionally taken phenology into account, but have used a single date for leaf-out averaged across all plant species. As participants in Nature’s Notebook know first-hand, the timing of leaf-out varies by species.

In Memory of Joseph Caprio (1923-2011)

Mon, Oct 31, 2011

Joe Caprio initiated the first spatially extensive phenology monitoring in the United States. As a professor in the College of Agriculture at Montana State University, he collaborated with agricultural experiment stations in the 1950s to employ phenology to characterize seasonal weather patterns and improve predictions of crop yield. This project eventually included around 2,500 volunteer observers distributed throughout 12 Western states.
