Establishing Provenience for 19th-Century Tree Specimens

From 1881 to 1905, Charles Sprague Sargent, Director of the Arnold Arboretum, worked in collaboration with Morris Ketchum Jesup, President of the American Museum of Natural History, to assemble for exhibit a set of logs representing every known tree species from the United States. While Jesup envisioned a beautiful display, Sargent hoped for a useful collection that would embody his own earlier report on the census of American forests. Known as the Jesup Collection of North American Woods, these more than 500 logs were exhibited at the Museum in the early twentieth century, but they were never employed in the study of the trees the way Sargent had envisioned. Although those logs reside in storage today, more than a century later, they are still possessed of scientific potential. This work is aimed at reconstructing the geographic origins of the logs from archival resources, providing an essential foundation for their use in future scientific studies.

The Botany of Cyrus Pringle
Summary: Cyrus Pringle's career as a professional botanical collector began with expeditions to the western United States in the early 1880s. In the course of his work, he brought numerous new species to science and contributed to broader knowledge of plant species' geography. Several of his specimens are the only records for species in locations in which they no longer occur, and as such also serve a conservation purpose in our own era.

Historic Riparian Vegetation
Summary: The historic (pre-1920) riparian flora of the Tucson Basin comprised species typical of floodplain, channel, and cienega settings. In many cases, herbarium specimens are the only records of these plant species from the flora area prior to the disappearance of the rivers, and the collected flora may be the best record available of plant species in a lowland riparian setting in the Sonoran Desert for this time frame.

Sonoran Desert Plants & Landscapes
Summary: Botanical field work in small mountain ranges of the northwestern Sonoran Desert, including the Sawtooth Mountains and the Table Top Mountains, has contributed to regional floristic inventories and natural-area conservation. Other work has contributed to the plant geographic and taxonomic literature for species of the desert region.

Spatial Variability in Saguaro Growth

Cactus in four populations of saguaros across an elevation gradient in the North Maricopa Mountains were measured for height in 1987 (marked by hailstone damage to the stems) and 2003. Initial height was a strong predictor of current height, but a poor predictor of change in height. Change in height exhibited a positive, qualitative relationship with elevation.

Studies in Neotropical Deciduous Forest
Summary: Tropical deciduous forests of the Pacific Slope of Mexico occur in a belt of a globally threatened forest type, in which land-cover conversion associated with agricultural and pastoral land use has been increasing for decades. Satellite remote sensing technology has several applications to analyses of habitat loss and forest dynamics. This project has explored forest vegetative phenology, in particular, as it varies spatially and with rainfall.

Urban Land Cover Change in the Tucson Basin, Arizona
Summary: Residential and resort development has increased on the bajadas and in the foothills of the Santa Catalina Mountains north of Tucson, disturbing and replacing desertscrub and xeroriparian vegetation. Using satellite imagery to map urban land cover in 1984 and 1998, I found that the area of urban land cover in the proximity of washes across the study area increased significantly between the two years. For washes explicitly recognized by planning ordinances, proportion of urban land cover did not increase significantly in the proximity of the washes.
