Hacienda de Gila: dendroarchaeology, architecture, and history at the Lyons and Campbell Ranch, Gila, New Mexico.

Buildings have stories. The materials, architecture, design, decoration and other attributes reveal life histories of a structure and often show changes through time. Sometimes, however, the stories are hidden and must be coaxed out of the building. Such is the case of the original Lyons and Campbell Ranch headquarters in Gila, New Mexico. Known in the 1890s as headquarters of the largest cattle ranch west of the Mississippi, the Lyons and Campbell Ranch actually has a much longer and more intriguing story.

Applications of acanthochronlogy on the Altiplano cactus Echinopsis atacamensis...or how I learned to love the bomb (pulse).

Cactus on the Altiplano of South America contain an archive of useful climate, physiological and demographic information in the isotopes of their spines. As demonstrated on saguaro cactus in Tucson, Arizona, spines emerge from the apex of the cactus, cease growth, and then are retained in time-ordered sequence on the side of the cactus as the stem continues to grow upward. Thus, time ordered sequences of spines contain diurnal, seasonal, and annual information in the oxygen and carbon isotope ratios of the robust spine tissue.

Field Guide to a Hybrid Landscape: Nebraska’s hand-planted forest

Dana Fritz will speak about her new book and exhibition, Field Guide to a Hybrid Landscape. This fascinating and little-known story of the first federal tree nursery and what was once the world’s largest hand-planted forest reaches beyond Nebraska with relevance to our current challenges of climate chaos and biodiversity collapse.
