an ASA Zoom Webinar*

 

Phenology studies seasonal cycles in nature that affect plants, animals and climates and how they are impacted by variations in the cycles. It studies key components of life on earth, researching the abundance and distribution of organisms, ecosystems, food webs and water cycles. Birds time their nesting so eggs will hatch when insects and plants are available to feed nestlings. Insect emergence is timed to coincide with leaf blossoming in plants they feed from. Farmers rely on these cycles to know when to apply fertilizer and insecticide.

Across the world many spring events are occurring earlier and fall events are happening later than they did in the past. Many species are not keeping pace with these climate changes, leading to mismatches in cycles and threats to survival. How plants and animals respond to climatic changes predicts whether or not they will thrive or become endangered. This makes phenology a leading source for indicators of climate change impacts.

The USA National Phenology Network was established in 2007 by professional and amateur scientists, governmental and research institutions, to collect, store and share phenological data. Its research focuses on global conservation and resource management using cutting edge geospatial tools such as Geographic Information Systems (GIS) mapping, drones and satellites, and data modeling.

Theresa Crimmins, Director of the USA-NPN and research professor at the School of Renewable Resources at UA will discuss how USA-NPN supports natural resource management through its National Coordinating Office (NCO) which provides data, tools, resources and people to advance the science of phenology.  

Professor Crimmins received her BS in Biology (1995) and MA in Geography (1997) from Western Michigan University in Kalamazoo and her PhD in Renewable Resources from UA in 2005.
