SKsaltonsea

Sarah Kimball (2007 to 2011) – Sarah has worked with me for a long time, both in her current position and as a post-doc in Tucson. She worked on this long-term shared project with Larry Venable, trying to understand the physiological underpinnings of the population and community dynamics of desert annual species. She focused on both the contemporary patterns of response to climate and trait relationships in the context of natural selection in field settings for a number of important species.

Kolby

Kolby Jardine (2008 to 2009) – Kolby is a physiological ecologist interested in trace-gas emissions from plants and atmospheric chemistry. He’s now at the Earth Science Division of the Berkeley National Labs. Kolby worked on developing techniques and instrumentation for measuring chemistry within plant canopies and the role of autotrophs in their emissions. He’s now working on the Green Ocean Amazon Terrestrial Ecosystem Project.

He’s interested in soil dynamics and biotic-abiotic controls over biogeochemical cycles. Mitch is a assistant research professor at the University of Arizona’s Biosphere 2.

amy

Amy Angert (2005 to 2007) – Amy is a plant ecologist with interests in community ecology and plant evolution. She focuses on species geographic distributions, asking questions about what limits adaptation at the edges of species’ ranges. He is an associate professor at the University of British Columbia in Vancouver.

Darrel

Darrel Jenerette (2005 to 2007) – Darrel is an ecosystem ecologist or maybe a landscape ecologist, who is interested in the coupling between biodiversity, energy fluxes, and biogeochemical cycling at large scales. He works across wild land, agricultural and urban settings and is particularly interested in water limited processes. He is associate professor of botany at the University of California, Riverside.

bobich

Ed Bobich (2004 to 2005) – Ed is a functional ecologist, who is interested in plant morphology and how traits relate to plant function. He’s worked on a number of anatomical, biomechanics and physiological problems associated with plants living in water limited habitats. He is an associate professor of biology at California State Polytechnic University, Pomona.

 


Past PhD Students

winkler

Daniel Winkler – (2013 to 2017) – Daniel is interested in a number of ecological phenomena, especially those relating to understanding species invasion and impacts on local biodiversity. Daniel worked in a number of landscape contexts (deserts, alpine), but always in a context of both an important basic science question and a compelling local land management need. He’s now off to work in the Colorado Plateau with Jayne Belnap and Sasha Reed

SmithMarielle

Marielle Smith – (2010 to 2017) – Marielle was my last student at the University of Arizona and she worked on forest structure in the Amazon. She was co-advised with Scott Saleska and is now working at a new post-doctoral position with Scott Stark at Michigan State.

AlbertLoren

Loren Albert – (2010 to 2016) – Loren was a PhD student in Ecology and Evolutionary Biology at the University of Arizona.

Potts

Daniel Potts – (2003 to 2005) – Dan is an associate professor in the Department of Biology at Buffalo State College. When he’s not swimming with sharks in some remote part of the globe he studies ecohydrology, physiological ecology and global change biology.
