Native Fish Lab- Staff

Dr. Dowling uses a variety of markers (morphology, allozymes, sequence and restriction endonuclease analysis of mitochondrial DNA [mtDNA]) to examine the processes responsible for the origin and maintenance of organismal diversity. He has directed his attention to the evolution of cypriniform fishes, one of the most diverse orders of vertebrates in North America. His studies are specifically focused on the process of speciation and the role of hybridization in evolution. This is being examined at three levels: 1) factors promoting population subdivision and producing incipient species, 2) the evolution of reproductive isolation, and 3) role of biogeography in the evolution of species. Examination of evolutionary pattern and process at these three levels of organization provides a complete picture of speciation in cypriniform fishes.

Dr. Dowling also applies these methods to the study of threatened and endangered fishes of the American Southwest. Quantification of levels of genetic variation within and between populations and species is crucial for preservation and management of this shrinking resource.

Ecological Personnel:
	Dr. Paul C. Marsh Owner and Principal Ph.D. 1979, University of Minnesota Ecology and Conservation of Southwestern Fishes Dr. Marsh's research deals broadly with aquatic ecology in the arid southwest, with emphasis on imperiled fishes of the region (a suite of indigenous taxa occupying a diversity of aquatic habitats in western United States and Mexico). Laboratory investigations supplement a strong field program examining basic life history characteristics and population community biology. These pursuits go hand-in-hand with applied management on behalf of target species. Activities are strongly collaborative with other faculty, with state and federal resource agencies, and with the private sector. Selected publications. Curriculum Vitae.
	Carol A. Pacey Project Manager M.S. 1996, Texas A&M University Ms. Pacey primarily maintains the mark and recapture database as well as analyzes and interprets field data for reports and publications. She also assists with field and laboratory work, makes presentations to professional groups, attends meetings and interacts with cooperators. Selected publications. Curriculum Vitae.
	Brian R. Kesner Project Manager M.S. 2004, James Cook University, Queensland, Australia Brian is interested in quantitatively assessing the status and trends of ‘big river’ native fish stocks in the Colorado River. His approach uses standard statistical techniques as well as developing and applying techniques that are unique to the type of data available and the difficulties associated with data for species that are rare and reintroduced. He also likes to get his feet wet occasionally and assists with monitoring programs throughout the Colorado River basin in Arizona and farther a field. Brian has worked for Dr. Marsh since 1998. Selected publications. Curriculum Vitae.
	Abraham P. Karam Project Manager M.S. Environmental Education 2005, Southern Oregon University, Ashland Abraham joined the Native Fish Lab in January 2006. Presently he his heading a project on Lake Mohave tracking razorback suckers via sonic telemetry. A native of south Louisiana, Karam relocated to Ashland, Oregon where he completed graduate school and worked on a suit of native fish species in the biologically diverse Klamath/Siskiyou bioregion. His thesis research took place in the Mohave Desert where he focused on artificial refuge management for Devils Hole pupfish. Selected publications. Curriculum Vitae.
	Guillermo Ley Fisheries/Aquatic Biologists B.S. Wildlife Conservation and Management 2007, University of Arizona Guillermo is interested in the role of native fish in riparian ecosystem health. He has worked with several fishes native to the Sonoran Desert, as well as amphibians, reptiles, and large mammals. He has worked extensively with these riparian fauna both in the laboratory and in the field. Other research interests include jaguar conservation in northern Mexico. Guillermo is developing and refining techniques to monitor razorback sucker recovery efforts in several locations along the lower Colorado River. Selected publications. Curriculum Vitae.
	Lori C. McIntosh Fisheries/Aquatic Biologists B.S. Wildlife Ecology 2006, University of New Hampshire Before joining the Native Fish Lab in July 2009, Lori worked in New Hampshire, Utah and Florida monitoring populations of fish, herpetofauna, birds and large mammals. Her interest in species and habitat conservation has brought her back to the southwest. Currently, she focuses on native fish research on Imperial National Wildlife Refuge, as well as other areas of the lower Colorado River. Curriculum Vitae.
	Christine M. Adelsberger Fisheries/Aquatic Scientist M. Sc. Fisheries and Aquaculture 2009, University of Arkansas Christie joined the native fish lab in November 2009. She is currently developing a monitoring program for bonytail chub released into Lake Havasu via sonic telemetry. A native of Oregon, Christie relocated to Arkansas where she completed graduate school. Her thesis work took place in Puerto Rico, working with fresh and brackish water fishes, and researching natural life history characteristics of bigmouth sleeper Gobiomorus dormitor. Curriculum Vitae.
