Clear Skies: A Herpetological Roast and Tribute for Young Cage

short article 40

7:15 PM Tuesday, 15 May University of Arizona, BIO5/Keating Building 1657 East Helen Street

Young and Cheryl Cage, married since 1981.

N ote from your Program Chair, Roger Repp: As many of you know, Young has been assailed by health issues of late. Originally, Mr. Cage was slated to give a presentation entitled “Some Thoughts on Nature Photography” for the 15 May program. Unfortunately, by 1 May, Young’s health had deteriorated to the point that he made the decision to enter hospice. He was incapable of delivering the program. In early May, he will go off the antibiotics that are keeping him alive, and will remain home with his loved ones until the end. Those who love Young most agree that this is the right thing to do. The recent passing of Jerry Feldner brought about an epiphany to me. That epiphany was how much Jerry would have enjoyed the company that gathered on his behalf after he was dead. Why not do something like this for the living?

It’s too late for Jerry—but for Young, it is not. We have the chance to honor all that Young has done for us and others on this night. We are lining up 10 speakers who know Young best. We are also including Young’s all time favorite 25 photos. At the end of it all, I hope to lead the group in a rousing chorus of “For He’s a Jolly Good Fellow.” (That should be good for a couple yucks!) We ask that you attend, whether you know Young Cage well, or don’t know him at all. This is the chance for us to send somebody off with the style and panache that is our trademark. Without further adieu, Young’s bio: Young Cage grew up in a military family where his father was an Air Force pilot. Fortunately for Young one of his father’s assignments took them to live in the Panama Canal Zone for three years. What better place for an aspiring wildlife enthusiast and herpetologist to live? After graduation from George Washington H.S. in Denver, Young attended Colorado State University with the thought of perhaps becoming a veterinarian. He decided to give aviation a hard try and he transferred to the University of Colorado at Boulder and graduated from the Aeronautical Engineering program. After a short stint as an engineer for McDonnell-Douglas, Young was hired by United Airlines at the ripe old age of twentyContinued on page 39

A Herpetological Roast and Tribute for Young Cage (continued) two with a whopping 200 hours of flight time. During his thirty-five years as a pilot Young flew engineer (Boeing 727, 737, and DC-10), Co-pilot (Boeing 737, 727 and DC-10), and his last twenty years as Captain (Boeing 737, 757, 767 and 777). As captain he flew internationally, mostly to Europe. Young was also active in the Air Line Pilots Association (largest airline pilot union in the U.S.). In addition to his years of being an active member he was elected Co-Pilot Representative for the Denver-based pilots. During the time when the pilots were pursuing the ESOP (Employee Stock Ownership Program) Young was elected as the Captain Representative for the Denver pilots. In this capacity he worked diligently to bring the ESOP to a reality. During the years of airline deregulation Young was the driving force behind instituting priority hiring for displaced pilots, beginning with the Eastern Air Line Pilots. Because of Young’s work, pilots who lost their jobs due to the bankruptcy of their airline had an opportunity to transition to United Airlines. Young also worked as a Captain IOE Instructor (Initial Operating Experience). In this capacity Young would be assigned new pilots flying their first trips within a new cockpit position (i.e., When a co-pilot would move into the captain’s seat. During this pilot’s first three-day trip Young would be his mentor/instructor in the cockpit). Young also did a great deal of groundbreaking work on aviation diversity issues. At the request of the company, Young worked on ideas and programs to make the pilot workforce more gender and diversity friendly. While enjoying his career, Young also pursued with great vigor and enthusiasm his love of herpetology. Happily for Young, his son, Matt, turned out to be a clone of his father carrying the same fascination for all things ‘herp’. Over the years Young and Matt have traveled to Costa Rica seven times, Peru twice, Australia twice, South Africa/ Botswana, Zimbabwe once, Mexico too many times to count and all around the

U.S. in pursuit of sighting snakes, frogs, lizards, and anything else that lives in the wild. Young and Cheryl, his wife, also traveled together extensively including a remarkable trip to Ecuador and the Galapagos Islands in 2009. Young worked diligently to educate people about the importance of our natural world. He was elected President of the Colorado Herpetological Society and the Tucson Herpetological Society. He was also on the Board of Directors for the Friends of Ironwood Forest in Tucson. Always willing to share his passions, Young has sparked several young people to pursue their natural history passions as professions. Years ago Young was asked to take an aspiring eight-year old nature lover out road hunting. This young man wrote about his experiences searching for snakes with Young in his college application packet and is now pursuing a career in biology. When Young and Cheryl moved to Tucson, Young’s passion went into overdrive. He added to his herping a desire to become a good photographer. His pursuit has turned out to be a huge success as there are now many homes and restaurants around Tucson that display his nature photography. On the home front Young has been just as fortunate. From his early first marriage he was given two of the best kids in the world, Matt and Kelly. When he and Cheryl married in 1981 the kids immediately took to Cheryl and they have been a tight, loving family ever since. Matt lives in Colorado with his wife Sheila and two great kids, Samantha and Brandon, and is a Sergeant with the Longmont Police Department. Kelly is a Nutritionist living in Stamford, CT, with her husband Lou and two wonderful girls, Abigail and Tigist.

Reproduction of the Spiny Chuckwalla (Sauromalus hispidus) and the Piebald Chuckwalla (Sauromalus varius) (Squamata: Iguanidae) from Mexico Stephen R. Goldberg, Whittier College, Department of Biology, Whittier, California 90608; sgoldberg@whittier.edu Kent R.

he Spiny Chuckwalla, Sauromalus hispidus Stejneger, 1891 is known from the Gulf of California islands of Ángel de la Guarda, Cabeza de Caballo, Flecha, Granito, La Ventana, Mejía, Piojo, Pond, San Lorenzo Norte, San Lorenzo Sur and Smith (Grismer 2002). The Piebald Chuckwalla, Sauromalus varius Dickerson, 1919 is known from the Gulf of California Islands of San Esteban, Sonora and Roca Lobos (Grismer 2002). The biology of S. hispidus and S. varius are summarized in Grismer et al. (1995) and Lawler et al. (1995). The most detailed information on reproduction in S. hispidus and S. varius is in Case (1982, 2002). Other information is in the following reports from captive specimens. Carl and Jones (1979) reported on eggs and hatchlings of S. hispidus and Sylber (1985) reported on hatchlings of S. hispidus and S. varius. The purpose of this paper is to present additional information on the reproductive biology of S. hispidus and S. varius from a histological examination of gonadal material from museum holdings. Due to the difficulty in justifying collections of large monthly lizard samples, use of museum collections for obtaining reproductive data has become increasingly important. A sample of 48 S. hispidus consisting of 25 females (mean snout-vent length, SVL = 255.9 mm ± 23.8 SD, range = 219-304 mm), 9 males (mean SVL = 243.0 mm ± 26.7 mm SD, range = 206-283 mm), 13 subadults (mean SVL = 160.5 mm ± 39.1 SD, range = 85-203) and one neonate (SVL = 70 mm) collected

from 1921 to 1978 and 16 S. varius consisting of 4 males (mean SVL = 281.3 mm ± 16.9 SD, range = 263-304 mm), 8 females (mean SVL = 272.4 mm ± 19.9 SD, range = 240-304 mm) and 4 subadults (mean SVL = 173.8 mm ± 27.5 SD, range = 133-193 mm) collected from 1931-1967 was examined from the herpetology collections of the Natural History Museum of Los Angeles County (LACM), Los Angeles, California; the San Diego Society of Natural History (SDSNH), San Diego, California; The Museum of Vertebrate Zoology (MVZ), University of California, Berkeley, California, USA; the California Academy of Sciences (CAS), San Francisco, California, USA (Appendix 1). The snout-vent length (SVL) of each specimen was measured from the tip of the snout to the posterior margin of the vent to the nearest mm. The left gonad was removed from each S. hispidus and S. varius and embedded in paraffin. Histological sections were cut at 5 µm and stained by hematoxylin followed by eosin counterstain (Presnell and Schreibman 1997). Enlarged follicles > 5 mm length and oviductal eggs were counted. Histology slides were deposited in the CAS, LACM, MVZ and SDSNH. An unpaired t-test was used to compare S. hispidus and S. varius male and female mean body sizes (SVL) using Instst (vers. 30b, Graphpad Software, San Diego, CA).

he authors provide additional information on tree climbing of an adult Gila Monster (Heloderma suspectum) from a population in the Sonoran Desert of south-central Arizona. The individual discussed in this paper is the subject of an ongoing radiotelemetric study in which various features of behavior, physiology, and spatial ecology have been investigated since March 2001. On 25 April 2010, at 1205 h, in an area of interfacing bajada and desert flats, an adult male Gila Monster was radio-tracked and located beneath a moderate-sized Yellow Paloverde (Cercidium microphyllum). Upon detection, the Gila Monster began a deliberate (non-erratic) and Radio-telemetered Gila Monster (Heloderma suspectum) #15 goes arboreal on 25 April consistent ascent into the tree that con2010—and earns the nickname “Tarzan”.

The authors were unable to determine whether the Gila Monster made his ascent to escape their presence or for other reasons, such as avoiding high ground temperatures. The authors did not locate bird nests in the tree, thus, it appears unlikely that foraging was a motivation to climb. To date, there are no observations to support arboreal foraging in H. suspectum.

The Wildlife Techniques Manual

Baltimore, Maryland, USA. ISBN-10: 1-4214-0159-2; ISBN-13: 978-1-4214-0159-1; Product Dimensions: 11.3 Ă— 8.9 Ă— 3.0 inches; 1136 pages. $150.00.

T

he 7th edition of The Wildlife Techniques Manual is a landmark publication that will certainly become a classic and highly recommended tool (Figure 1). The 7th edition is completely revised and updated, and for the first time appears as a two-volume set. Volume 1, with 22 chapters, covers techniques in wildlife research, and Volume 2, with 15 chapters, covers techniques in wildlife management (see Table 1 for a complete list of chapters). Since its original publication in 1960, The Wildlife Techniques Manual, a concept created by The Wildlife Society, has remained the cornerstone text for the professional wildlife biologist. Every decade or so (Figure 2) the book is revised, edited, and updated. As new techniques are developed, new chapters are warranted. Edited by Nova J. Silvy, the new edition covers new methodologies used in the field and laboratory. Topics include experimental design, wildlife health and disease, capture techniques, population estimation, telemetry, vegetation analysis, conservation genetics, wildlife damage management, and urban wildlife management. As I read through the manual, one chapter in particular caught my attention: Chapter 5, use of dogs in wildlife research and management (Dahlgren 2012). I have a keen interest in the use of dogs in conservation because I worked with a dog handler in the early 2000s searching for the often elusive San Joaquin kit fox (Vulpes macrotis mutica; Smith et al. 2006). My dog handler colleague, Dr. Deborah A. Smith, was indeed a co-author on this chapter and I was very pleased to see her work mentioned in this manual. Certainly, the use of dogs in wildlife studies would seem to be a new thing. In assuming this, I am wrong. The 4th edition was the first to have a chapter specifically on the use

of dogs in wildlife biology (Zwickel 1980). However, a chapter specific to dogs as wildlife management tools did not appear again until the 7th edition. The ebb and flow of chapter topics represents how the wildlife research community perceives demand for various field techniques and methods. Chapter 6 is an important example of how relevant The Wildlife Techniques Manual is to current events (Sheffield 2012). At 9:45 PM, CDT, on 20 April 2010, the Deepwater Horizon offshore oil drilling rig exploded and resulted in a significant oil spill along the Gulf Coast. Chapter 6 addresses how to identify and handle contaminant-related wildlife. Various contaminants are addressed including mercury, lead, cadmium, solvents, ethylene glycol, and petroleum products. As new environmental catastrophes develop due to demands of our ever-changing world, The Wildlife Techniques Manual will be right there to provide guidance and techniques to preserve and conserve our natural resources. The second volume of the 7th edition is key in understanding wildlife in the landscape and how it relates to the human dimension. With habitat loss, fragmentation, and modification, wildlife species are becoming displaced and have fewer places to go. The second volume discusses wildlife management in a variety of landscape types, including rangelands, inland and coastal wetlands, farmlands, and urban environments. As impacts to the remaining wildland areas continue, these chapters will become cornerstone guides for informing wildlife managers how to address a variety of wildlife management issues. Region-wide management plans will quickly become vital to the continued conservation of natural resources, and tools like Habitat Conservation Plans will (and should be

already) be a paramount force in wildlife preservation (Randel et al. 2012). In summary, this new and revised 7th edition could not have been published at a better time. The dynamic and changing landscape needs wildlife managers with a passion for wildlife conservation and preservation; this two volume techniques manual is a vital tool in accomplishing the goals and aspirations of local and global wildlife biologists to the betterment of our planet. As this 7th edition is field-tested and exercised to its limits, I predict an 8th edition will soon need to be developed, as loss of habitat, disappearing biodiversity, and the ever-expanding human population will create new challenges that will need to be quickly addressed before it’s too late.
