Webinar: Explore patterns in space and time with the Visualization Tool July 8, 2014
Phenology • The science of the seasons • Blooms and buds • Hibernation, migration, emergence • Easy to observe …it is the study of the timing of recurring plant and animal life-cycle stages, or phenophases, and their relationship to environmental conditions. Photo credit: L. Barnett
USA National Phenology Network Primary goal Create a standardized dataset for use in multiple types of research. Mission Make phenology data, models and related information available. Encourage people of all ages and backgrounds to observe and record phenology. Understand how species and landscapes are responding to climate change. Photo credit: C. Enquist

Observing change over time I observed an unusual circumstance this spring on the foothill of Moscow Mountain, northern Idaho, elev. 3000‘.I have been monitoring the arrival of hummers for many years here--they range in arrival from early to late April. Usually the Calliope is first, followed by the Rufous. Over the last few years, the Rufous have been either arriving at the same time or before the Calliope. This year the two were nearly simultaneous on Apr. 23. About a week later I spotted the Black Chinned--usually not often seen, and never before late June/July (followed in late summer by the Broadtailed).
Structuring observations April 23, 2012
Publications Models leaf budburst across the eastern U.S. under climate scenarios; by the end of the century, species like red maple will leaf out 17 days earlier. Develops more precise models for changes in ecosystem function in Alaska, accounting for the phenology of individual species, rather than estimating an average day of year across species. Cloned plants had a more consistent response to warming spring temperatures than natural populations

Questions – Graph Interface • Comparing across scales: How does red maple phenology compare across: individual tree, site, state and region? • Management: When do Siberian elm (invasive) and Cottonwood (native) fruit? • Species Interactions: • Monarch and milkweed • White-winged doves and Saguaros

Don’t get tripped up! • Lots of sites with no data • Check plant and animal leaderboards, to see which species have a good amount of data • On the tool, filter by species first • Species box – filters just limit species list, you can’t limit data by partner (yet) • Long loading time, especially with climate data
Other tricks Multiple site selection is key for looking at regional patterns Plot data, and then change location in the graph tool to compare regions or years Use direct URL to share your findings: http://www.usanpn.org/files/viz/index.html
What places, species or phenophases would you like to explore? Poll – more mapping or graphing?
What is this tool good for? • Seeing which species and locations are data-rich • Finding potential patterns • for example, relationships between climate and phenology • Answering straightforward questions • for example, did my poppies flower earlier or later this year than last year?
What is this tool NOT good for? • Conclusively showing a relationship between two species • Negative data is not completely taken into account (yeses override no’s in the graph if both are present for day/site/species) • Animals are more likely to be seen if people spent longer looking for them, this is not accounted for in the tool • Statistical tests (comparison of means, correlations) not available • Conclusively showing a relationship between climate variables and phenology
