Book Description
Winner of the Society for Economic Botany’s Mary W. Klinger Book Award The seemingly inhospitable Sonoran Desert has provided sustenance to indigenous peoples for centuries. Although it is to all appearances a land bereft of useful plants, fully one-fifth of the desert's flora are edible. This volume presents information on nearly 540 edible plants used by people of more than fifty traditional cultures of the Sonoran Desert and peripheral areas. Drawing on thirty years of research, Wendy C. Hodgson has synthesized the widely scattered literature and added her own experiences to create an exhaustive catalog of desert plants and their many and varied uses. Food Plants of the Sonoran Desert includes not only plants such as gourds and legumes but also unexpected food sources such as palms, lilies, and cattails, all of which provided nutrition to desert peoples. Each species entry lists recorded names and describes indigenous uses, which often include nonfood therapeutic and commodity applications. The agave, for example, is cited for its use as food and for alcoholic and nonalcoholic beverages, syrup, fiber, cordage, clothing, sandals, nets, blankets, lances, fire hearths, musical instruments, hedgerows, soap, and medicine, and for ceremonial purposes. The agave entry includes information on harvesting, roasting, and consumption—and on distinguishing between edible and inedible varieties. No other source provides such a vast amount of information on traditional plant uses for this region. Accessible to general readers, this book is an invaluable compendium for anyone interested in the desert’s hidden bounty.

Book Description
In 1995, Texas Historical Commission underwater archaeologists discovered the wreck of La Salle’s La Belle, remnant of an ill-fated French attempt to establish a colony at the mouth of the Mississippi River that landed instead along today’s Matagorda Bay in Texas. During 1996–1997, the Commission uncovered the ship’s remains under the direction of archaeologist James E. Bruseth and employing a team of archaeologists and volunteers. Amid the shallow waters of Matagorda Bay, a steel cofferdam was constructed around the site, creating one of the most complex nautical archaeological excavations ever attempted in North America and allowing the archaeologists to excavate the sunken wreck much as if it were located on dry land. The ship’s hold was discovered full of everything the would-be colonists would need to establish themselves in the New World; more than 1.8 million artifacts were recovered from the site. More than two decades in the making, due to the immensity of the find and the complexity of cataloging and conserving the artifacts, this book thoroughly documents one of the most significant North American archaeological discoveries of the twentieth century.

Book Description
This dissertation presents the result of two separate research programs. The first elucidates the phylogeny, biogeography and systematics of the genus Menodora in the olive family. A phylogeny based on the internal transcribed spacer (ITS) of nuclear ribosomal DNA and the chloroplast rps16 and trnL introns and trnL-F intergenic spacer demonstrates that the genus is monophyletic. Within the genus, M. robusta of Patagonia is the first taxon to branch, followed by a monophyletic African clade and M. spinescens of California, though the placement of the latter does not have strong support. Most North American species are nested within the derived South Americans. A South American origin is hypothesized, with two independent dispersals to North America, and a single dispersal to Africa. The phylogeny provided new insights for the systematic treatment, where 24 species, one subspecies and six varieties are recognized, with major realignments of the intregrifolia and scabra species complexes, and a single new species described. In the second area of research, the chloroplast genome of Pelargonium × hortorum has been completely sequenced. At 217,942 base pairs (bp), it is both the largest and most rearranged land plant chloroplast genome yet sequenced. It features two copies of a greatly expanded inverted repeat (IR) of 75,741 bp each, and diminished single copy regions of 59,710 bp and 6,750 bp. Gene content is similar to other angiosperms, with the exceptions of a large number of pseudogenes, two open reading frames (ORF56 and ORF42), and the losses of accD, trnT-ggu, and possibly rpoA. The latter may be represented, however, by highly divergent set of rpoA-like ORFs. The IR expansion accounts for most of the size increase of the genome, but an additional 10% is related to the large number of repeats found. Most of these occur near rearrangement hotspots, and two different repeat associations (characterized by full or partial duplications of several genes) are localized in these regions. We propose simple models that account for the major rearrangements with a minimum of eight IR boundary changes and 12 inversions in addition to several sequence duplications.

Book Description
Fernanda Antunes Carvalho addresses an issue of key importance to the field of systematics, namely how to foster taxonomic work and the dissemination of scientific knowledge about species by taking full advantage of electronic data and bioinformatics tools. The first part focuses on the development of an electronic monograph of the papaya family (Caricaceae) using existing infrastructures of Information Technology (IT) and bioinformatic tools that together set the stage for a new era of systematics. Based on the plastid and nuclear DNA data, the author inferred historical processes in the second part that may have shaped the evolution of the Caricaceae and explain their current geographic distribution. The last part is dedicated to the evolution of chromosome numbers in the Caricaceae and includes counts for species from three genera (Cylicomorpha, Horovitzia, Jarilla) that have never been investigated before.
