Abstract: The dwarf mistletoe parasitizing bristlecone pine on the San Francisco Peaks, Arizona is shown to be Arceuthobium microcarpum, instead of A. cyanocarpum as reported previously. The dwarf mistletoe causes serious localized damage, but it is not considered to be a serious threat to the bristlecone pine population.

Book Description
Interweaving lovely, meticulously drawn pictures with a story line that spans 5,000 years, Alexandra Siy invites young naturalists to explore the secrets of the world's oldest trees--secrets of the earth's climate, recorded in their tree rings, and secrets of the bristlecones' resilience, as a species that lives in the harshest of environments. Living for more than five thousand years, ancient bristlecone pines are the oldest trees on Earth. Recorded in their rings are "secrets"--scientific evidence of a changing planet. A volcano erupts in 2036 BC. In 775, a storm explodes on the sun. Lightning strikes in 1122. And during the 20th century, the temperature increases dramatically. What is the secret to the bristlecone's exceptionally long life? Alexandra Siy's lyrical text, paired with Marlo Garnsworthy's meticulously researched mixed media paintings, reveals the life cycle of the mysterious ancient bristlecone pine. "Still growing, safe and strong in its place in the sun, the bristlecone's secrets are waiting to be discovered by anyone who can read its rings."

Book Description
Covering a large swath of the American West, the Great Basin, centered in Nevada and including parts of California, Utah, and Oregon, is named for the unusual fact that none of its rivers or streams flow into the sea. This fascinating illustrated journey through deep time is the definitive environmental and human history of this beautiful and little traveled region, home to Death Valley, the Great Salt Lake, Lake Tahoe, and the Bonneville Salt Flats. Donald K. Grayson synthesizes what we now know about the past 25,000 years in the Great Basin—its climate, lakes, glaciers, plants, animals, and peoples—based on information gleaned from the region’s exquisite natural archives in such repositories as lake cores, packrat middens, tree rings, and archaeological sites. A perfect guide for students, scholars, travelers, and general readers alike, the book weaves together history, archaeology, botany, geology, biogeography, and other disciplines into one compelling panorama across a truly unique American landscape.

Book Description
Over the past thirty years, late Quaternary environments in the arid interior of western North America have been revealed by a unique source of fossils: well-preserved fragments of plants and animals accumulated locally by packrats and quite often encased, amberlike, in large masses of crystallized urine. These packrat middens are ubiquitous in caves and rock crevices throughout the arid West, where they can lie preserved for tens of thousands of years. More than a thousand of these deposits have been dated and analyzed, and middens have supplanted pollen records as a touchstone for studying vegetation dynamics and climatic change in radiocarbon time (the last 40,000 years). Now, similar deposits made by other mammals like hyraxes are being reported from other parts of the world. This book brings together the findings and views of many of the researchers investigating fossil middens in the United States, Mexico, Africa, the Middle East, and Australia. The contributions serve to open a forum for methodological concerns, update the fossil record of various geographic regions, introduce new applications, and display the vast potential for fossil midden analysis in arid regions worldwide. The findings presented here will serve to foster regional research and to promote general studies devoted to global climate change. Included in the text are more than two hundred charts, photographs, and maps.
