Recently I was reminded of this wonderful video short on the vegetation history of the Sierra Nevada which was made with Jim Thorne. It tells the story of the Wieslander VTM project and features lots of photos and great GIS visualizations, plus banjos! Enjoy!
The UC Natural Reserve System hosted a food and music filled midday fair on Tuesday, August 11, 2015. Michelle and Heather of the Holos team demonstrated the site and answered questions from a broad range of visitors to the Ecoengine table, including members of the UC Office of the President and the UC Berkeley campus.
A recent publication in Global Ecology and Biogeography, by Maldonado et al., Estimating species diversity and distribution in the era of Big Data: to what extent can we trust public databases?, brought up some very interesting topics about the quality of specimen data available to researchers.
The Holos website and Ecoengine tools have reached a major milestone-- we've removed the public password and will demonstrate the site at the BIDS Data Science Faire on May 5th. Most of the Ecoengine Team will be there to answer questions and hear reactions and new ideas. We have been looking forward to this day!
Patrick McIntyre (Ecoengine postdoc) and co-authors present their article, "Twentieth-century shifts in forest structure in California: Denser forests, smaller trees, and increased dominance of oaks" in this month's Proceedings of the National Academy of Science. The authors, which include Ecoengine PIs Maggi Kelly and David Ackerly, used the newly mobilized Wieslander Vegetation Type Mapping data to examine changes in forest structure from the 1930s to 2000s. They discovered that while tree density has increased over the time period there been a decline in forest biomass, which reflects a shift from larger trees to smaller trees. Furthermore, forest composition has moved toward increased dominance by oaks relative to pines. Read the full article here.
