Seminar Title: Large-scale ecological responses to climate change in space and time

Seminar Abstract: Recent climate change is posing tremendous impacts on our planet, but how do Earth’s species and ecosystems respond? Here I discuss two aspects of large-scale ecological responses to climate change: geographical range shift in space and phenological shift in time. The biogeographical resurvey analysis suggests widespread upslope species migration in response to warming in North and South Americas. In particular, tropical montane plants and animals were tracking climate more closely than their temperate counterparts. The remote sensing analysis suggests an overall extension of the growing season with concurrent warming across the Northern Hemisphere, with stronger climate tracking at higher latitudes. Phenological shifts outpaced that of temperature change in natural landscapes but lagged behind those in human-dominated landscapes. Examining large-scale responses in space and time may benefit scaling ecological insights into the Earth system.

Short Biography: Dr. Kai Zhu is an assistant professor of environmental studies at the University of California, Santa Cruz. His research areas are global change ecology, ecological modeling, and environmental data science, with a current focus on plant and soil responses to environmental change. Dr. Zhu is a recipient of the Tansley Medal from the New Phytologist Foundation and an elected Early Career Fellow from the Ecological Society of America. He completed his postdoc at Stanford University and received his PhD in ecology and MS in statistics from Duke University.

The first week of January, before the first day of classes on January 7, the labs in E2-311 and E2-305 will do some house cleaning and reorganization. Here is a list of items:

• E-waste any Scorpion equipment that cannot be repurposed.
• Decide to keep/discard/donate remaining parts and equipment.
• Shred boxes of old exams (2 years old or more).
• Reorganize everything that remains.
• Create an inventory of everything and place in a Google Doc.

Once the BTS parts have been organized, Kerry will contact John Steele.
