Director’s View

On the east flank of the Chiricahua Mountains in Cave Creek Canyon, each season passes in such a regular cyclic fashion that one comes to accept climatic changes, as in the 2002 spring drought that closed the Coronado National Forest from May 28 through July 18, as part of still other planetary cycles of nature. So isolated, sometimes the impacts of social catastrophe elsewhere in the world are not apparent immediately at the Station.

Nevertheless, on September 11, 2001, we watched in shock — along with the nation — the events in New York City. Later, in November, we saw the smoldering remains of the World Trade Center towers on a trip to the American Museum of Natural History. And we noted the nearly empty halls as visitation to such cultural institutions in the City drastically plummeted. Following the immediate tragedy of loss and disruption of lives, new negative economic realities hit New York City and the Museum. By the first months of 2002, the Station was frantically trying to adjust to 20 percent retroactive budget cuts, which were soon continued into the upcoming season and forward into the July 1 budget year. So, a good part of the staff’s efforts in 2002 have been directed toward maintaining the services of the Station at a level comparable to that of before, but with significantly reduced resources. To date, we feel that we have accomplished this positively, not without the assistance of visitors throughout the year.

Courses, training programs, and workshops always bring a forward-looking orientation to activities at the Station as they prepare participants to better understand the natural world. In June, Bat Conservation International held its tenth year of three-consecutive workshops on bat field biology, having now trained nearly 450 people over that period. In August, The Bee Course returned for its fourth annual session and the Ant Course for its second — both leading efforts on an international level in the training of advanced taxonomy in invertebrates for professionals from around the world. Two scientists brought groups of outstanding high school students from the Student Challenge Awards program of the Earthwatch Institute to participate in studies on the dynamics of whiptail lizard foraging behavior and the mating flights and genetics of harvester ants. Meetings included the Arizona Native Plant Society’s annual Labor Day Chiricahua Workshop, the Horned Lizard Conservation Society’s Fifth National Conference, the Southwestern Association of Biologists conference, Jasper Ridge Biological Preserve docents (Stanford University), and the joint retreat of the University of Arizona’s Departments of Biochemistry and Molecular Biophysics and Molecular and Cellular Biology. Courses introducing students to the wonders of nature in the Chiricahua setting included those from the University of Arizona, Pima Community College, Cal Poly Pomona, Garrett Community College, Kino School, and the Menaul School. Educational tour programs — Field Guides, Inc., and Geronimo Educational Foundation’s Elder Hostel — focused on the bird diversity and natural history of the area. The community of scientists that utilized the Station continued studies that enhance our understanding of the natural world; results of this carefully uncovered knowledge are noted in Recently Received Publications (pp.7-8). New dissertations and master’s degree studies were initiated this season, as former students terminated their multiple-year studies. Other “students of Nature” carried on long-term studies on Mexican jays, painted redstarts, harvester ants, unisexual lizards, spiny lizards, horned lizards, tadpoles, slave-making ants, owls, etc. Informally, hundreds of “naturalist” (or non-scientist) guests came to enjoy the Station, taking with them enhanced understandings of the natural world. And so, the growth of knowledge continues.

Sixteen Years of Scientific Guidance

By Wade C. Sherbrooke

SOUTHWESTERN RESEARCH STATION

The Southwestern Research Station (SWRS) of the American Museum of Natural History (AMNH) has served, and been home to, a wide spectrum of field scientists from throughout the United States and other countries around the world since 1955. Administratively, it has been extremely important to incorporate the views and perspectives of active research scientists into the programs and development of future planning of SWRS by the Museum.

In 1987, in creating the Southwestern Research Station Scientific Advisory Committee, I sought the assistance of scientists willing to volunteer their advice to the AMNH administration on the significance and role of the Station in science. Members of the Committee usually serve three-year, rotating terms; and, since 1993, graduate students in residence have held one-year positions. Annual reports are sent to the chief scientific administrator at the Museum in New York, currently Dr. Michael J. Novacek, Senior Vice President and Provost of Science.

The contributions of this Committee and its members over the years have been felt by all at SWRS. Their recommendations have led to many improvements, and they have played important roles in the Station’s modernization via National Science Foundation grants.

I want to make all visitors to the Station aware of the important services of these individuals (see adjacent list) and again thank them for their valuable guidance over the last 16 years.

Reminder

A reminder to all scientists planning to conduct research at SWRS in 2003—please contact our office EARLY (January) to reserve space, request applications, etc. Make sure to get your applications back to us early, as well. We are already filling in rapidly and want to make sure we have space for YOU!

A Tale of Two Species: Exploring Hybridization in Harvester Ants

By Sara Helms Cahan

University of Lausanne

Lausanne, Switzerland

The study of harvester ants (genus Pogonomyrmex) at the Southwestern Research Station has had a long and distinguished history, for good reason. They are the most conspicuous and easily-observed inhabitants of the valley grasslands, with large-bodied and charismatic (if grumpy) workers, large, active colonies, and spectacular mating flights. These characteristics also make them ideal as a teaching tool to learn about the goals and process of scientific research. Recently, it has been discovered that the harvester ants in southeastern Arizona show some extremely unusual genetic patterns at both colony and population levels, spurring a renewed interest in the evolutionary history and biology of these ants and providing a rare opportunity for students to participate in the beginning stages of research into a new and poorly understood biological phenomenon. For the last two summers, Glennis Julian from the University of Arizona and I have been conducting research on these ants, accompanied by teams of high school students selected by the Student Challenge Awards Project (SCAP), a program administered by the Earthwatch Institute.

One of the defining features of ant societies is the presence of two distinct forms, or castes, of females. Queens specialize on reproduction, while workers perform all of the non-reproductive tasks for the colony. In almost all ants the differences between queens and workers are not caused by genetic differences, but by differences in their environment such as temperature or food quality. There are a few rare cases where castes do differ genetically, however, including certain populations of two harvester ant species, Pogonomyrmex barbatus and

P. rugosus. Each population is composed of two genetically distinct groups. Whether a female is a reproductive queen or a sterile worker depends on who her parents were. Queens are almost always the daughters of parents from the same genetic group, while their worker nestmates are always hybrids, daughters of parents from different genetic groups.

The SCAP teams have conducted a variety of experiments to further understand how and why such a bizarre system occurs in these populations. They have designed and conducted a controlled mating experiment in the field to see if queens mated only to males from the same genetic group can successfully raise the non-hybrid workers that are not seen in field colonies. They have surveyed colony genetic structures throughout Arizona and New Mexico to determine the geographic distribution of the phenomenon. And they have investigated the morphological and behavioral differences between workers produced in the populations where castes differ genetically and those where caste is purely environmental.

Participating in the Earthwatch expeditions has had a profound effect on the students, both from participating in research and from interacting with the SWRS community. At the beginning, the students were unsure of what to expect, and had not been overly excited when they found out they would be working on something as unimpressive as ants rather than wolves or dolphins. In the group journal, Emily Wang summed up her expectations this way: “When I first got the letter that told me I would be studying ants, I got itchy all over: my arms, legs, and the back of my neck felt as if ants were crawling all over, all of a sudden.” After two weeks, however, despite the long hours, the frustrations of experiments that don’t work, and numerous ant stings, the students felt a real connection to the project and to scientific research in general. After our first expedition was over, two students, Emily Wang and Debbie Wechselblatt, stayed on at SWRS as volunteers, helping out with research projects as diverse as owl behavior, beetle diversity, and conservation of desert stream ecosystems. Bri Beeghly, a graduate of the first team, returned this past summer to serve as the student mentor for the second team. Whether any of the students decide on biology as a career remains to be seen, but at the very least the program has given them an appreciation for the value of, and need for, basic research that they will carry with them long after the expedition is over.

Cave Creek Ride

By Bill Ogroski

Greater Arizona Bicycling Association

I’m an avid hiker and lover of nature, so how could I resist the Cave Creek ride? Well, for starts, I didn’t have a bike. But my friend Perry brought in various newspaper ads of local sales until I stopped off at a bike shop and picked up a mountain bike. Unfortunately, I didn’t have any free weekends to do any serious riding, but did sneak in a 9-mile ride to/from Saguaro National Park. “Just ten times that and a bit more elevation gain and I’d be up to Cave Creek” I told myself! But somehow, I wasn’t convinced I could handle it. I voiced my concerns to Perry and my other biking friend, Diana, and was given all sorts of invaluable advice about bike shorts/shirts/padded seats, gloves, and so on. So I ran by a couple of bike stores to “gear up.” It was a very busy Friday evening, preparing for my first bike trip. So busy, in fact, that I only ended up with four hours of sleep! I was very thankful when Diana volunteered to drive.

At 6:00 am, amid a beautiful Arizona sunrise, she pulled into my driveway. In no time at all, she had my bike on her rack, and we were zooming down I-10…destination: Road Forks, NM. After checking in with Cathy, our ride leader, putting our gear in the sag van, upping my air pressure to 40 pounds (came from the store with 29, and was told that was awfully low for a “road trip”!), and a quick stop in the nearby restaurant to, hopefully, avoid any unplanned stops along the way, we began our journey. The cool morning air enhanced the anticipation as I joined the 19 other riders on our trek southward. The scenery was already picturesque, with mountains decorating the horizon, as if to say, “come see me”. But I was clueless as to how much the beauty would soon be unfolding before me in the miles ahead.

At 9:48 am, I was pulling in to our first rest stop. I’ve never tasted such delicious ice-cold orange drink in my life! We shared some muffins, enjoyed the soothing music that was filling the air, received the latest directions from Cathy, confirmed that everyone was having a great time, and then returned to the road.

By 11:00 am, we had our second rest stop and were beginning the climb up highway 533 to Portal. Although the ascent was constant, we were distracted by both the wildflowers that began appearing alongside the road and the lure of the mountains that were beginning to draw near. The continual climb slowed (most of) us down enough to facilitate meeting some of the other riders along the way. It’s amazing how fast the time passes when you’re surrounded by such beauty and involved in conversation with other riders. So, the hour it took us to get to the Portal Store just flew by. But boy did it ever feel good to get out of the saddle for a bit! We had a very relaxing lunch and were entertained by the hummingbirds that were continually fluttering overhead.

As we returned to our bikes and left Portal behind, we knew we only had five miles to go before we made it to our destination — the Southwestern Research Station. But, we were also warned that the climb was real and the scenery would be breathtaking. We certainly weren’t disappointed — the beauty was truly inspiring! It’s a good thing this was not a race, as I found myself being distracted at virtually every turn of the road. First it was the sound of rushing water — I had to check out the nearby creek. Then the creek followed along the road, providing constant “music for the soul”. Next stop was in response to the rustling of leaves — it was a deer exploring the forest. I resisted the temptation to venture too far off-road in hopes of a picture and continued my journey. Towering formations of the Chiricahaus began to decorate the skyline, providing “postcard views” in every direction. Trees towered overhead, providing a shaded passageway for most of the remaining journey.

Even with all the stops along the way, by 2:00 pm, it became quite clear that the spring-fed pool we were told about wasn’t just someone’s dream…there it was before my eyes, inviting us to jump in for a refreshing swim! We had made it to our destination — the Southwestern Research Station. After checking into our rooms, most everyone found their way to the pool. Just cool enough to be refreshing. After that refreshing dip, those of us that were able to locate some energy to spare followed Cathy for a wonderful hike up South Fork Canyon. As we hiked beneath the huge trees, there was a continuous display of incredible rock formations providing the perfect contrast to the deep blue sky and billowing white clouds. On the trail in front of us, the wildflower displays would make even a florist jealous! I kept finding myself falling behind as I just couldn’t resist taking “one more picture”. As we continued up the canyon, the water began flowing in the creek alongside. As beautiful as it was, we had to cut the hike short in order to make it back in time for the 5:00 pm happy hour!

Soothing music once again filled the air, while popcorn, crackers, and wine provided the perfect pre-dinner appetizers. We each took turns introducing ourselves, and learned of the history and mission of the Station, as well as the bear sighting by two of the riders. Then it was off to the dining hall to enjoy a wonderful BBQ chicken dinner, complete with all the trimmings. The acorn squash seemed to be a big hit for some, but my attention was captured by the pumpkin pie (or was it the whipped cream?), and a very yummy prickly pear dessert! After a very fulfilling meal, Cathy unveiled her “secret slide show”…a tribute to her dear friend and cycling buddy, Elena. She shared slides from the many rides they had done together over the years, amazing all of us…especially a “newbie” like myself!

Following the slide show, Diana entertained us with numerous selections on her guitar. Several songs and stories later, we agreed that it was time to call it a night. Once back to the cabin, I questioned all the blankets on our bed, but was told that the prior night it had dropped to 44 degrees! Brrrr! I don’t know about the rest of the group, but speaking for cabin 6, although it was barely after 9:00 pm when I hit that bed, I remember very little else (and I believe I was the last one to turn off my light). We all slept very very well!

Sunday morning was there before we knew it, greeting us with its cool, crisp mountain air. And the deer was also there to greet us once again as we packed up our gear and headed over to the dining hall for breakfast. After another delicious meal, we prepared our sack lunches and then began the journey back down the canyon. The views were every bit as gorgeous as on the way up! In no time at all, we were down the canyon and back at US 80, making our climb up that killer hill. It was going up this hill that I was definitely thankful I had a “low gear”. I was also thankful to see Jim and Elena there with the blanket spread out for us to enjoy our lunches on once we had conquered that hill…how wonderful that felt. And, after that, it was just a “tad further,” and there was Cathy waiting for us to “cross the finish line”. What an awesome introduction to the world of cycling! Anyone heard when the next Cave Creek ride is going to be?!

2002 Volunteers

The Southwestern Research Station would not be the same place without the volunteers who join us each season to apprentice themselves to the scientists who are conducting research here or to do their own research. While here, they provide housekeeping and maintenance duties for us. A great big thank you for all the assistance provided by the volunteers who came from near and far to experience the Southwestern Research Station this year!
