New Explorations on the Río Mayo

In Collaboration with The Southwest Center

Did you know that the Sonoran Desert originated in part from the tropics? The Río Mayo drainage of the Sierra Madre mountains near Álamos, Sonora, Mexico, is a convergence zone of astonishing biological and cultural diversity. Research into this unique and imperiled ecosystem at the Desert Laboratory on Tumamoc Hill extends back to the 1940s. Please join the Desert Laboratory and The Southwest Center for this series as we venture back to the Río Mayo and hear from a diversity of researchers and community members who will highlight new explorations, biocultural understandings, and efforts to preserve the tropics next door.

La Vaquita Marina: Where do we go from here?

In Collaboration with CEDO, Intercultural Center for the Study of Deserts and Oceans celebrating their 40th anniversary

La Vaquita Marina, a small porpoise endemic to the upper Gulf of California, is on the precipice of extinction. Global scale economic pressure fuels local gill-net fishing that ensnare the vaquita, driving their numbers down to as few as a dozen individuals remaining. This lecture series with experts from Mexico and the United States will explore what lessons we can learn from an intertwined web of science, local and global economics, politics, black markets, and conservation. What can be taken from this dire situation for future conservation? Where does the middle ground exist and how do we get there?

Campos de Fuego: Explorations of the Pinacate 

Since the Hornaday expedition set off from the Desert Laboratory in 1907, captured in the book Camp fires on Desert and Lava, there has been a unique connection between Tumamoc Hill and this enigmatic volcanic range in NW Mexico. Recognized by many as the desert’s heart, the Pinacate has captivated and inspired those who have traversed its rugged slopes, peaks, and dunes. Please join four of those individuals as they connect you to this special region of our desert and in celebration of the first bilingual publication of the 1928 novel Campos de Fuego: A Brief and Fantastic History of an Expedition into the Volcanic Regions of the Pinacate by Gumersindo Esquer, Contribution 2 of the Proceedings of the Desert Laboratory.

Oasis: Biodiversity Gems in the Southern Sonoran Desert

Presenter: Michael Bogan, Assistant Professor, School of Natural Resources and the Environment

In the arid southern Sonoran Desert, the rugged canyons of the Sierra El Aguaje contain a surprising number of freshwater oases fed by groundwater that rises through geologic faults. At least 220 species of aquatic animals, including six undescribed species, have been documented from the oases in recent years. Genetic evidence from fish and frogs suggests that these or similar spring-fed habitats have persisted in the mountain range for thousands to millions of years. Groundwater pumping, the introduction of non-native species, and unmanaged human recreation all pose threats to the biodiversity of these unique desert oases.

The Multiple Forces of Natural Selection on Seed Size in a Desert Annual Plant

Presenter: Eugenio Larios, Postodoctoral Fellow, Instituto de Ecologia, UNAM

Seed size is a key plant functional trait that has fitness consequences through the life cycle and therefore under selective pressure. While seed size has been of general interest to ecologists and evolutionary biologists, selection on seed size has proven to be difficult to measure in the wild. The speaker will show how selection on seed size in Dithyrea californica is influenced by three environmental; forces in the wild: water availability, intraspecific competition, and selective predation by ants and rodents

No Species is an Island: A Science-Art Collaboration

Presenter: Ted Fleming, Emiritus Professor of Biology, University of Miami & Kim Kanoa Duffek, Nature Artist & Illustrator, Botany Department, Arizona-Sonora Desert Museum

Dr. Fleming and Ms. Duffek  will talk about the novel discoveries that he and his research team made during an 11-year study of the pollination biology of four species of Sonoran Desert columnar cacti. These discoveries are described in the book, “No Species is an Island: Bats, Cacti, and Sonoran Desert Secrets” recently published by the University of Arizona Press. They include the odd breeding system of the cardon cactus; the highly specialized pollination system of the senita cactus; and the amazing life-history of the nectar feeding bat, Leptonycteris yerbabuenae, an important pollinator of cardon, saguaro, and organ pipe cacti. The book’s illustrator, Kim Kanoa Duffek, and Dr. Fleming will also discuss how they came to collaborate on this book.

Beyond Cattle and Grains: Adaptation to Global Change in Arid Rural Communities

     Wednesday, November 8 6:00 p.m.

America Lutz Ley, Assistant Professor, Center for Development Studies, El Colegio de Sonora

People in rural Sonoran communities, as in other places of the world, adjust their behaviors not only in face of climate change, but in response to the combination of multiple types of stressors. This research shows that the livelihood profile -or what people do for a living- in the rural communities, importantly influences the type of stressors they perceive as a priority for adaptation. In general, modifications in the environment and climate events are perceived widely, but climate change as a large scale process is under-recognized in the Sonoran communities analyzed.
