Roland “Ro” Wauer is retired from the National Park Service where he worked in several of America’s national parks.

His favorite parks include Big Bend in Texas, Death Valley in California, and Zion in Utah. He has traveled extensively in Mexico and throughout the U.S. and Canada.

He is the author of 25 books and more than 180 articles on nature, especially about birds and butterflies. He continues writing about our natural resources, presenting talks, and conducting research on birds and butterflies.

Richard Wiegand has worked as an air traffic controller, a newspaper photographer, and, for the last twenty-five years, as a Regional Biologist for the Maryland Natural Heritage Program, charged with the task of locating, identifying, protecting and documenting rare, threatened and endangered species and habitats in the state.

A recognized authority on the flora of the mid-Atlantic, federal, state and local government agencies, as well as private and corporate clients, have contracted his services to provide biological resource inventories and environmental impact statements for places as disparate as the Presidential retreat at Camp David, Fort Detrick, the C&O Canal National Historical Park and the entirety of Shenandoah National Park.

Wiegand completed a two year photography curriculum in Miami, Florida and studied with Dr. Szell, a close student and companion of Ansel Adams for many years. 

Richards' images have appeared in over fifty publications, several books and numerous illustrated reports. 

He has provided thousands of stock photos to, among others, the websites and archives of the Smithsonian Institution, the Philadelphia Academy of Science, the U.S. Fish and Wildlife Service, The Nature Conservancy, the World Wildlife Fund and multiple State Natural Heritage Programs. 

His work has been exhibited throughout the mid-Atlantic region.

Tyler Nordgren is a Professor of Physics and Astronomy at the University of Redlands. Prior to arriving at Redlands in 2001 he was an astronomer at both Lowell Observatory and the U.S. Naval Observatory in Flagstaff, Arizona.

He earned his PhD in astronomy from Cornell University in 1997 for work on dark matter in interacting spiral galaxies. In addition to publishing roughly two dozen peer reviewed scientific articles he is also the author of “Stars Above, Earth Below: A guide to astronomy in the national parks,” a popular science book dedicated to revealing what visitors to America’s national parks can observe in a dark night sky. Since 2007, Dr. Nordgren has worked closely with the U.S. National Park Service Night Sky Program to promote astronomy outreach and night-sky preservation in national parks.

Dr. Nordgren has helped document this vanishing landscape with award-winning artwork and night sky photography that has been on display in galleries from New York City to Flagstaff, Arizona and is on display in a number of national parks. As a result of this work he was a past-member of the Board of Directors for the International Dark-Sky Association. In 2012, NASA’s Curiosity rover joined Spirit and Opportunity on Mars carrying sundials, or “Marsdials” which Dr. Nordgren helped design with a team of seven other scientists and artists.

Nature artist and naturalist Robert O'Brien is one of the most prolific and widely published contemporary botanical illustrators in the United States.

Specializing the illustration of trees and their natural history, Robert has illustrated over 70 tree and forestry education publications for organizations across the United States from Florida to Alaska, as well as Europe and Africa.

His work has also been featured in regional, national and international newspapers and magazines.

Robert maintains his home and studio in the Texas hill country west of Austin. In addition to his successful graphic design and illustration business, he is currently working on a series of etchings of birds of the Gulf Coast and Caribbean as well as a book of North American trees.

He is also making available large limited edition prints of his tree illustrations.

More of his work can be viewed on his website at: http://www.treeguides.com.

Diane grew up in Louisiana and attended Tulane University where she studied biological illustration, art history and the natural sciences.

She graduated in 1982 with a Bachelor of Science degree in Biology and Biological Illustration and moved to Florida with her husband, a marine biologist.

Because of her lifelong love of fishing, she decided to choose ichthyology as her illustration specialty. Her watercolor fish illustrations are in high demand for conservation, nature and scientific publications.

Her oil paintings have been featured on state and conservation fishing stamps, magazine covers, and books.

She continues to prioritize projects that enhance conservation of our natural resources, and supports many organizations and charities with her time and donation of artwork.

Diane currently serves as Vice President of the Florida Foundation for Responsible Angling.

Houston is home to many snakes and is also where Clint’s passion for snakes began.

As a 5 year old child, Clint was reading reptile books from the local library  and his elementary school, and by third grade he had read every available reptile and amphibian book. 

Clint has has been studying and catching snakes, venomous and nonvenomous, from that moment to this moment.
At the age of 11, he met a local nature scientist, Dr. Robert A, Vines, who taught Clint how to catch and handle venomous snakes and better ID venomous from nonvenomous. This was 1970 and snake grabbers were not readily available as they are today, so Clint learned how to make his own grabbers, snares, hooks and pinning devices, and continued practicing and honing his skills over the years.

He received a B.S. in Communications from the University of Houston. Clint has also been featured in many newspapers, magazines and regularly asked to do television interviews. 

He continues traveling around Texas entertaining and teaching audiences (companies, schools, TPWD, etc.) of all sizes and ages how to properly ID snakes, what do in case of envenomation, and overall handling and safety. 

Arlene Ripley, an avid birder and photographer, became fascinated with butterflies while living in Southern Maryland.

Never outdoors without a camera in hand, she began censusing the butterflies that occurred in her home county and produced a butterfly checklist for the nature park where she was a volunteer.

Her interests expanded to observing and photographing not only adult butterflies but learning their life histories by raising them from eggs deposited on their host plants.

She enjoys giving presentations to local birding and butterfly clubs. At the peak of her study of Eastern butterflies, she and her husband left the East Coast and now reside in southeast Arizona where she continues her love of "all things nature."

Arlene has degrees in Biological Science and Medical Technology. She is always looking for birds and butterflies to photograph whether they are in her own yard or while on world travels.

Steven Schwartzman has been a photographer since the 1960s.

In recent years his nature photographs and accompanying articles have appeared multiple times in Texas Highways and Wildflower, the magazine of the Lady Bird Johnson Wildflower Center.

Steven hosts the nature photography blog at portraitsofwildflowers.wordpress.com.

Craig Springer is a biologist and writer, living in northern New Mexico.

Joseph Tomelleri graduated from Fort Hays State University (Hays, KS) in 1984 with a M.S. in biology. After working briefly as a field biologist, Joe took to illustrating fishes full time.

He has drawn scientific illustrations of more than 1000 fishes from actual specimens, most of which he has collected and photographed in the wild. His drawings have appeared in more than 750 publications.

He is a lousy photographer and races bicycles in his spare time. Joe lives in Leawood, Kansas with his wife Susan and their two sons—who rarely, if ever, listen to their mom and dad. http://www.americanfishes.com and http://www.fishmatrix.net
