Sponsored by the College of Science, this series of public talks, given by University of Arizona professors and graduate students bring the community together in a casual setting to learn about the latest research being conducted. You can get to know the faces behind the science, have opportunities to ask questions and deepen your understanding of the world around you. There are five, separate café series at different locations around Tucson now including Tucson Botanical Gardens.  Come join the conversation!

First Thursday of the Month, March to May 2020, 6 to 7 p.m.

The New Deforestation Threat: Amazonian Rainforests and the Global Environment

Thursday, March 5, 6–7 pm, Free

Dr. Scott Saleska, Professor, Department of Ecology & Evolutionary Biology

Talk Description: Tropical deforestation reached a crisis in the Amazon in 2019, and the latest science shows how this will likely have impacts not only in South America but around the world. This is because these vast forests, often called the “lungs of the planet”, are both sinks for carbon and geysers of water, and are connected through the atmosphere, to the pulse of the planet’s climate and environment.


The Biosphere 2 Rainforest, a Magnifying Glass for Ecosystem Responses to Environmental Changes

Thursday, April 2, 6–7 pm, Free

Dr. Joost van Haren, Assistant Research Professor, Biosphere 2, Interdisciplinary Faculty, Honors College 

Talk Description: Biosphere 2 is an iconic facility that allows scientists to experiment with environmental conditions and observe how the land surface or ecosystems respond. A scaled-down, model version of biosphere 1 (the Earth), serves as a magnifying glass on how ecosystems interact with the atmosphere where researchers can compare a mini-closed system to better inform large-scale ecosystem models. I will present the research conducted by Columbia University when it managed Biosphere 2 and preliminary results from the current large-scale international experiment (B2_WALD) tracing carbon and water through vegetation and soil.

The Ecology of Water Harvesting

Thursday, May 7, 6–7 pm, Free

Dr. Vanessa Buzzard, Senior Research Specialist, School of Natural Resources & the Environment

Talk Description: Water harvest systems are common in residences throughout Tucson, but little has been done to explore how these systems impact ecological processes. We set out to classify changes in ecosystem processes relating to soil health after installation of various water harvesting systems. We assessed variation in soil properties and microbial diversity following installation of three water harvesting treatments; passive, irrigated, and greywater basins. Overall, our observations indicate that water harvesting influences the ecology of soil systems, which may play an important role in conserving groundwater!
