Dr. Rebecca J. Best
I am an aquatic community and evolutionary ecologist interested in the processes that determine the number and type of species we find coexisting in a particular community, and the way those communities function. My lab works on the effects of climate on aquatic connectivity, species distributions, and the ecology and evolution of riparian tree traits.
Dr. Hillary F. Cooper
I am an evolutionary ecologist interested in how organisms can respond to environmental stress via genetic or plastic mechanisms. As a post-doc in THE BEST lab and the Cottonwood Ecology Group, I will be studying the evolution and ecological consequences of phenotypic plasticity to climate change and insect herbivory in cottonwood trees, and how it may then affect communities of dependent organisms. I earned a PhD in Biology at NAU in 2018 researching genetic and trait variation in cottonwoods.
Iris Garthwaite (MS Environmental Sciences and Policy)
Iris joins the lab from Evergreen State where she worked with Dr. Carri LeRoy and started building her science twitter reach! Iris brings substantial experience with the growth and decomposition of riparian plants, and will be working on trait plasticity in collaboration with the Cottonwood Ecology Group.
Yazhmin Dozal (MS Environmental Sciences and Policy)
Yazhmin is completing her MS as a Fellow with the RISE Program for Environmental Health research, and is studying the relationship between changing aquatic environments, the distribution of mosquito larvae, and disease. Previously, Yazhmin graduated as the Distinguished Senior for the College of the Environment, Forestry, and Natural Sciences at NAU. She was Co-Chair of the NAU Green Fund Committee and an active member of The Wildlife Society’s NAU chapter.
Susan Wood (MS Environmental Sciences and Policy)
Susan is working on the control of invasive crayfish species in Arizona, in collaboration with David Ward at the USGS and with funding and input from the US FWS Southwest Non-Native Aquatic Species Community of Practice.
Joshua is completing his BS in Environmental Sciences with a minor in GIS. As a 2x Hooper Undergraduate Research Award recipient, he has already worked on the impact of transgenerational plasticity on the growth and reproduction of native and introduced amphipods, and is now working on the recovery of pond invertebrate communities following extreme drought.
Joann Jeplawy (MS Environmental Sciences and Policy)
Now at: Tetra Tech, Denver, CO. In collaboration with the Cottonwood Ecology Group, Joann studied the impacts of leaf plasticity on aquatic community composition in cottonwood leaf litter from three common gardens in Arizona and Utah.
Kaitlin Haase (MS Environmental Sciences and Policy)
Now at: Xerces Society for Invertebrate Conservation, Santa Fe, NM. Kaitlin studied the biodiversity and connectivity of natural and anthropogenic ponds across northern Arizona in relation to aquatic habitat loss due to climate change.
Lindsay Hansen (MS Environmental Sciences and Policy)
Now at: USGS, Flagstaff, AZ. Lindsay studied the increasing abundance of a native fish (the flannelmouth sucker) in the Colorado River by modeling growth rates in response to changing water temperature in the Grand Canyon. She was co-advised with Brett Dickson and in collaboration Charles Yackulic.
As a NASA Space Grant intern, Dylan investigated the use of eDNA as a tool for aquatic biodiversity monitoring across a temperature gradient. Dylan is completing both a BS in Environmental Sciences and an MS is Climate Sciences and Solutions through the 4+1 program.
As a Hooper Undergraduate Research Award recipient, Matthew worked on understanding trait variation in aquatic insect larvae, and how multiple environmental tolerance traits have evolved across orders and families.
Morgan Andrews (BS Environmental Sciences)
Now at: USGS. As a Hooper Undergraduate Research Award recipient, Morgan worked on the effects of water temperature on the distribution of aquatic biodiversity across ponds in Arizona, using both field and lab approaches. She was awarded the Best Poster in Applied Research at the 2019 Society for Freshwater Sciences meeting in Salt Lake City, Utah!
Kaitlen Bieber (BA Environmental & Sustainability Studies)
Kaitlen helped launch the lab’s stock pond biodiversity work before spending her third year studying abroad at UNAM (Universidad National Autonomous de Mexico) in Mexico City. She is currently working on picking the perfect graduate program!
Lauren Mason-Sarantopulos (BS Environmental Sciences)
Now at: AZGF. As a 2x Hooper Undergraduate Research Award recipient, Lauren created and carried out two independent research projects on the effects of temperature and nitrates on native vs. introduced amphipods in Arizona, both within and across generations.
Madelyn Norstrem (BS Environmental Sciences)
Madelyn worked as an NSF REU student to help lead the lab’s study of herbivory and climate change impacts on cottonwood trees. She also worked as an Interns to Scholars student studying aquatic invertebrate communities.
Joe Sweet (BS Environmental Sciences)
As a NASA Space Grant intern, Joe worked on using remote sensing to detect the presence of water in ponds across the northern Arizona landscape, giving us much greater spatial and temporal information on habitat availability.
