Phenology: using natureís calendar to study global change

Juliet Oshiro is a PhD candidate at UC Santa Cruz in the Ecology and Evolutionary Biology Department. She studies how plant blooming times respond to climate in the grassland and sandhills vegetation types in Santa Cruz County.

This type of work is called phenology - the study of life cycle events. Itís also referred to as the study of natureís calendar. Life cycle events are often cued by environmental conditions such as temperature and precipitation, so naturally phenology has been a hot topic for research in an era of global change. Many species of plants and animals have advanced their calendar over the past century in response to increased temperatures.

In order to find meaningful patterns such as these, phenology research requires large datasets that span multiple years and locations. In recent years phenology researchers have developed a number of ways to involve citizen scientists in the data collection process.

Julietís talk will cover how to become part of this effort, both independently and through the upcoming UC Santa Cruz Arboretumís Phenology Walk program.

Juliet's talk takes place on Monday January 12 at 7:30 pm. The location is the UCSC Arboretum Meeting Hall, 1156 High Street, Santa Cruz across from Western Drive.

Note that one walk, on January 18 from noon to 1pm, is set aside as a CNPS event. Meet at the entrance to the Arboretum Native Plant Garden. See http://arboretum.ucsc.edu/education/phenology-walk/ for other dates. .
