My broad research interests include population biology, predator-prey dynamics, conservation biology, evolutionary ecology, and behavioral ecology of large mammals.  I pursue these interests primarily through field research with large carnivores, large herbivores and the landscapes they occupy.  My general approach to research is to design and conduct field studies that will most directly test a priori hypotheses or generate novel insight using known individuals, direct observation, or non-invasive sampling but I also enjoy developing and testing theories based on modeling or meta-analyses of existing data.

Primary Department/Unit: 

My research interests lie at the cross section of ecology and human geography, particularly the complex social, political, and economic factors that play into landscape conservation and the impact of environmental protection on human societies.  I am interested in the proliferation of payments for ecosystem services programs, including carbon markets, as a potential method of ecological management and livelihood improvement.

Topic or title of your dissertation/thesis: 

My thesis research in Guatemala will investigate local land user participation in carbon offsetting programs to determine if these international market-based initiatives do provide equity and benefits to communities involved in addition to carbon sequestration.

My research dissertation research focuses on collaborative and participatory applications of Geographic Information Systems (GIS) and Remote Sensing (R/S) technologies to improve communication and use of scientific knowledge for wildfire planning and management.  I am also a research associate for the Regional Center for Sustainable Economic Development through Arizona Cooperative Extension, where I conduct research to help identify the most sustainable areas for renewable energy development throughout the state using GIS modeling. And I love bicycles

Other Departments or Unit Affiliations: 

I am a PhD student in ecology at the University of Arizona where I also work as a Research Intern in Bioinformatics and Geospatial Analysis for an iPlant Seed Project on Botanical Geospatial Diversity Cyberinfrastructure. My research broadly centers on the topics of species diversity, biogeography and macroecology; in this realm I study patterns of species diversity, species distribution modeling, and am particularly interested in the mechanisms that both enable and constrain organisms to live where they do in the context of climate change. While some of my work is continental in scale across diverse organisms, a significant component is also targeted at understanding the limits of the distribution of Sonoran desert and Mojave Desert plant species. Before pursuing academic studies in ecology I worked for resource conservation agencies and later in the geographic information systems (GIS) field as programmer, specialist and project manager. So, I also have 15+ years of experience with information systems and GIS in both local and state government, non-profit, and private industry settings. I am a Certified GIS Professional by the GIS Certification Institute and an esri Certified ArcGIS Desktop Professional.

Topic or title of your dissertation/thesis: 

My dissertation centers on studies of the determinants of the distributions of organisms at a variety of scales. This effort is focused around the idea of understanding how distributions are constrained by biotic and abiotic processes so that we can begin to assess how the distributions of organisms may be influenced by climate change.

Christopher Cokinos is a nature-and-science writer with strong interests in a variety of topics, including climate change (especially geoengineering), extinction, traditional natural history, space sciences, the search for extraterrestrial intelligence and improving science communications.

The winner of a Whiting Award, Christopher Cokinos is the author of two literary nonfiction books, Hope Is the Thing with Feathers: A Personal Chronicle of Vanished Birds and The Fallen Sky: An Intimate History of Shooting Stars, both from Tarcher/Penguin.Hope Is the Thing with Feathers won the Glasgow Prize and the Sigurd Olson Nature Writing Award. For The Fallen Sky, he was awarded a National Science Foundation grant to participate in a meteorite-hunting expedition in Antarctica, and that book was a finalist for the Saroyan Prize.

His books have been featured and praised in such venues as "All Things Considered", People magazine, the Boston Globe, Nature, Science, Natural History, among others; His poems, reviews, aphorisms and essays have appeared widely in such publications as Poetry, Science, Birder World, Hotel Amerika, Orion, The New York Times and The American Scholar; His essays have won the John Burroughs natural-history essay prize and the FineLine Lyric Prose Prize from Mid-American Review
He contributes to both the Los Angeles Times and High Country News His current book project is a history of the scientific search for extraterrestrial intelligence.  In May 2011 he left Utah State University, where he taught for nine years and founded and edited Isotope magazine, to join the MFA program and the Institute of the Environment at the University of Arizona, where he is an Associate Professor.

I am interestd in the effects of habitat fragmentation and isolation on avian dispersal, and how to improve current habitat restoration practices within the current agricultural landscape. I am developing genetic markers in yellow-billed cuckoos as a tool to measure current western riparian connectivity.

Topic or title of your dissertation/thesis: 

Yellow-billed cuckoo Coccyzus americanus population genetics within a fragmented landscape.

Primary Department/Unit: 

After interning with the Nevada division of the Bureau of Land Management (Conservation and Management program, 2007), then interning for National Wildlife Federation's public affairs office and working for another year in Washington, DC, on climate policy, I decided to return to science and academics. I am interested in how and when similar species can coexist, which drives biodiversity and its changes.

Topic or title of your dissertation/thesis: 

Buffelgrass (Pennisetum ciliarus syn Cenchrus ciliarus) is a perennial C4 grass native to Africa and Southwest Asia. It has been planted extensively for five decades in semi-arid regions, such as Australia, Brazil, and Sonora, for cattle forage. Over the past thirty years, however, buffelgrass has colonized ecosystems outside of the pasture, where it fills in bare space to become a fire hazard and decrease native vegetation diversity. This has become a serious problem in Southeastern Arizona, where buffelgrass does very well in the habitat of the iconic saguaro cactus and has fueled enormous wildfires.
I propose to develop a stage-structured model with variable growth and survival rates to investigate how buffelgrass may be excluding native vegetation. I will consider both resource competition and variable predation by granivores and herbivores as density-dependent mechanisms. I will also incorporate buffelgrass removal as an additional source of mortality, and ask at what level that mortality must be set in order to preserve native diversity, and how the native community should respond when buffelgrass is removed.
I propose to parameterize this model and test its predictions in a field experiment along the wildland-city border in the foothills of the Catalina Mountains just north of Tucson. I hope to begin pilot studies later in the spring of 2011.
