Self-Reflections of a Conservation Biologist

Taylor Edwards

Dr. Taylor Edwards, Associate Staff Scientist at University of Arizona Genetics Core, will present a self-evaluation of his research and how his experiences have shaped his approach as he moves forward in the future.

Taylor is a conservation geneticist whose primary research focus for the last 20 years has been the desert tortoise. He was instrumental in revising the taxonomy of this group into what are now three independent species, including the newly described “Goode’s thornscrub tortoise.”

Throughout his career, Taylor has sought out interdisciplinary collaboration and research projects that inform and promote species conservation. In 2019, Taylor was part of an exhibition at the University of Arizona Museum of Art as part of the Next-Generation Sonoran desert Researchers 6&6 Project: Six Artists, Six Scientists—Merging Views of the Sonoran Desert.

With artist Heather Green, he explored an isolated population of chuckwallas near La Cholla, Sonora, Mexico.This transformative experience exposed him to a transdisciplinary approach that has inspired his tactics toward conservation.

About Dr. Taylor Edwards:

Taylor first moved to Tucson in 1992 to work in the Department of Mammalogy and Ornithology at the Arizona-Sonora Desert Museum. This was his first introduction to the Sonoran Desert, and he’s been a passionate advocate ever since. He is currently an Associate Staff Scientist at the University of Arizona Genetics Core where he has been involved with a variety of genetic projects from fish to plants to people, including helping to oversee the public testing for National Geographic and IBM’s “Genographic Project.”

Taylor earned his Bachelor of Arts in Zoology from the University of California, Santa Barbara and then both his Masters and Doctorate degrees in Wildlife and Fisheries Conservation and Management from the School of Natural Resources and the Environment at the University of Arizona. He is a member of the Advisory Board of the Turtle Conservancy, a Scientific Advisor for the Turner Foundation for the Bolson Tortoise Captive Breeding and Repatriation Project and past president of the Tucson Herpetological Society. Taylor also works with National Geographic and Lindblad Expeditions as a “National Geographic Expert” and has accompanied programs to US National Parks, Costa Rica, Panama, Nicaragua, Peru, Ecuador, and the Galapagos Islands.

August 28 Field Trip – Sabino Canyon Day and Night 2019

/in , , /by

We will spend a few hours herping in the morning, ending when temperatures are getting too warm for lizards and then re-converge in the late afternoon for a few hours at night. Weather-dependent.

Logistical Lead and Contact Info: Larry Jones. 520-730-5254; gilaman@comcast.net

NOTE: Plans are subject to change, usually due to weather, so keep your cell phone with you, especially the day before and day of the trip, and especially for the night portion, should nasty storms brew.

Location: Sabino Canyon Recreation Area, Coronado National Forest.

Target Taxa: The daytime is mostly for lizard watching through binoculars. Close-focus are best. Nighttime is mostly for snake-viewing. This is a good area for many species of snakes and lizards, including Sonoran Spotted Whiptail, Giant Spotted Whiptail, sometimes Eastern Collared Lizard, and a host of other common lizards, especially those of the Sonoran Desert. Snakes include Sonoran Lyresnake, kingsnakes, Black-necked Gartersnake, and other common desert snakes. Venomous species include Gila Monsters, Western Black-tailed Rattlesnakes, Tiger Rattlesnakes, Western Diamond-backed Rattlesnakes, and Arizona Coralsnakes. Amphibians include several toads and Canyon Treefrogs. Sonoran Desert Tortoises are reasonably common here.

Herp Handling Requirements: This is a no-touch zone.

Meeting Area/Rendezvous Point: Meet at the front of the Visitor’s Center. There is a parking fee that the participants must pay themselves. Hang onto the stub, and use it for re-entry.

Meeting Time and Date: On the morning of 28 August, meet at the visitor’s center at 0630 AM. It is likely to be hot, so an early start is necessary for the day portion. Then after the long lunch and dinner break, meet again at 6:30 PM for the evening portion.

Leaving Time and Date: During the morning, probably leave by 11:00 or so. At night, probably leave at 10:30 PM or so. This is determined as we go. Leaders and helpers of smaller groups will have walkie-talkies and or cell phones to communicate.

Directions: At east end of Tucson, in foothills of Santa Catalina Mountains, at entrance to Sabino Canyon

Accommodations (e.g., campground): Hotels and camping in and near Tucson, but nothing right there.

Facilities: Visitor’s Center, restrooms with flush toilets. There is no food at Sabino Canyon; one would have to bring their own, or head out after the break. There are paved roads and good trails.

Carpooling: No arranged carpooling. However, if participants from the West side want to carpool to Sabino, go for it.

Maximum Number of Participants: 15 persons.

Off-limits Areas: Adjacent private lands are off-limits. Walking will be limited to roads, trails, and possibly the riparian area; however, in the event of monsoonal rains, the riparian area may be dangerous, so at night, it is mandatory to stick by a trail and/or stay with the group helper.

Site-specific Safety Alerts: Daytimes can get very hot, so be prepared. We have no plans to guide the field trip during the heat of the day, so participants are on their own. During moderate weather, rattlesnakes and Gila Monsters may be common, as well as stinging insects. In the afternoon and evening, flash floods, rising stream levels, and lightning are potential safety hazards. If the conditions look too hazardous, we will cancel or postpone the evening field portion. Participants must always stay close to their group helpers, or announce when they are headed back. If were are in underbrush, snakes are a hazard, and leather boots and snake gaiters are advised, and may be mandatory.

What should Participants Bring?: General field gear (e.g., boots, sunscreen, hat, food, water), binoculars (especially close-focus), cell phone, camera, FLASHLIGHT/headlamps required for nighttime portion. If you want to get off the pavement on trails at night, snake-gaiters may be required.

Purpose of Trip (e.g., photograph and release at point of capture): No-touch, photograph in situ the abundant reptile and amphibian fauna of this area. There are ¾ million visitors per year, so the lizards are often tolerant of humans, and it is often easy to get photographs of many species. This is a moonless time during the monsoon, so is categorically the best time for snakes, although it is dependent upon the local conditions.

Nearest Emergency Room with 24/7 Physician on Duty: Saint Joseph’s Hospital, 350 N. Wilmot Road, Tucson, AZ 85711. (520) 873-3000. Call 911 in an emergency.

Other Information as Needed: Because this trip is weather-dependent, be ready to change plans at the last minute. Watch for emails, texts, or phone message updates, especially in the days preceding the trip and the day of the trip.

Field Trip: Scorpions of the Tucson Mountains and Avra Valley

/in , , /by

On June 22, 2019, Saguaro National Park West will host a morning presentation by esteemed scorpion expert Larry Jones, and when the sun goes down, you can join scorpion enthusiasts for a night of sightings.

IMPORTANT: To register for the FIELD TRIP, you must contact Saguaro National Park at 520-733-5158. Registration is not required for the morning presentation.
Presentation: 22 June 2019, 10:15 AM

  • Special presentation by Larry Jones in the Saguaro National Park West Theater
  • No sign-up or registration necessary
  • Sponsors and Collaborators: Saguaro National Park West (SNPW), THS, Ironwood Forest NM (IFNM; BLM), Friends of IFNM, and Pima Co. Parks and Recreation

“During the past three years, I have studied scorpions of this area and amassed some 13,000 records of habitat and microhabitat use by six species of scorpions found in the area. I will discuss my research and give an overview of how to identify the species found there, as well as information on venom, precautions, and what to do if stung. Because this is also be a good area for snakes, we will have assistance from the Tucson Herpetological Society (THS) to look for the many interesting serpents of the Avra Valley, the area for the proposed I-11 corridor.”

Field trip (scorpions and any herps encountered): 22 June 2019

  • Meet at 8:30 PM, in front of the Visitor’s Center (VC). We will end around 11:00 PM
  • Sign-up by reservation only, through Saguaro NP 520-733-5158 (after announcement on website in mid-May). Do not sign up through THS!
  • Bring: Headlamps/flashlights, black lights, water, snacks, water, close-focus binoculars, sturdy hiking boots, cell phone, and camera with zoom and/or macro lens.

First, we walk around VC, then caravan to Avra Valley. For those not wishing to do the whole thing, they can leave after the VC portion (but you’ll be missing out!)

This trip targets most species of scorpions in the area, but we also hope to see some of the native snakes.

June 19th Presentation: Herp Population Dynamics at Leslie Canyon NWR

/in , /by

WHEN: Wednesday, June 19 at 7:15 pm
WHERE: Ward 3 City Building, 1510 E Grant Rd., Tucson, AZ

Mr. Bill Radke, Refuge Manager at Buenos Aires NWR, Leslie Canyon NWR, and San Bernardino NWR, will present a fascinating account of the population dynamics of reptiles and amphibians at Leslie Canyon National Wildlife Refuge.

The presentation will focus on the exciting results of an intensive 15-year sampling project at Leslie Canyon National Wildlife Refuge in Cochise County, Arizona, which culminated in October 2014.

Studies such as this one are important for helping document species richness, understanding ecological trends, investigating population dynamics and the roles of rare species, and in helping justify resource management decisions.

Not only did this study document population dynamics and “spikes”, information gleaned from this extraordinary effort included:

  • Species richness
  • Periods of activity
  • Success of various trapping techniques
  • Longevity information
  • Response to precipitation
  • Relative abundance

Additionally, the project resulted in the capture and identification of a new mollusk species, and helped with the determination of a new mammal species.

May 15th Presentation: Komodo Dragons in the Field

/in , /by

Thermoregulation, movement patterns and energy use by Komodo Dragons in the Field

Dr. Hank Harlow, Professor Emeritus, University of Wyoming

Hank Harlow is Professor Emeritus, Department of Zoology & Physiology, University of Wyoming, Laramie, Wyoming. He is interested in Comparative, Integrative, and Ecological Physiology of Vertebrates, Thermal Biology of Terrestrial Endotherms and Ectotherms, Biochemistry of Fat and Protein Utilization, Physiology of Stress, Spatial and Temporal Use of Terrestrial Landscapes. His studies have addressed animal adaptations to stressful environments, whether it is habitat loss influence on Sun bears in Cambodia, sea ice loss effect on Polar bear survival in the Arctic or invasive prickly pear cactus on big lizards in Indonesia. This talk will focus on addressing why it is not a large mammal, but a reptile, that is the top carnivore on five islands in Indonesia. The spatial and energy profiles of Komodo Dragons was created with the use of temperature loggers, VHF tracking, heart rate monitoring and respirometry to understand the behavioral and physiological adaptations of different size groups of dragons allowing them to coexist and effectively utilize limited resources.

April 17 Presentation: Herping with the Taliban in Afghanistan

/in , /by

Ted Pappenfus, UC Berkeley, will share his experiences as a herpetologist in Afghanistan at the April 17 meeting of the Tucson Herpetological Society.

Ted is a research herpetologist at the Museum of Vertebrate Zoology. For over 25 years his field work has included expeditions to arid regions in West Asia, the Middle East, the Arabian Peninsula, and the Horn of Africa in Somalia and Eritrea. He tries to visit historic type localities to collect fresh specimens and tissues for DNA and morphological studies of amphibians and reptiles from these countries.

In the year 2000, he contacted the Taliban rulers of Afghanistan and asked them if he could come to Afghanistan to “catch some lizards”. Ted was surprised how willing the Taliban leadership was have him “come catch lizards”.

It took several months for the Taliban to arrange the trip. He was met at the Pakistan border town Quetta, smuggled across the border and driven to the Taliban stronghold of Kandahar, Afghanistan.
Osama bin Laden was living in Kandahar at the same time Ted was there, but due to conflicting schedules they never met.
