    Description / Table of Contents: The second edition of The Jepson Manual thoroughly updates this acclaimed work, the single most comprehensive resource on California's amazingly diverse flora. This work integrates the latest science, the results of intensive fieldwork, institutional collaboration, and the efforts of hundreds of contributing authors into an essential reference on California's native and naturalized vascular plants. For the first time, the University of California Press is offering this resource as an e-book. The Digital Jepson Manual provides an unparalleled new level of interactivity, portability, and convenience. Extensive linking and e-book-friendly illustrations make it easier for users to learn about plant characteristics and identify the native and naturalized plants of California--all in a format ideally suited for use in the field. Using readily available e-book readers, field researchers, students, and enthusiasts can click on links to rapidly navigate through keys to families, genera, species, and subspecies or varieties. Specific features of The Digital Jepson Manual include the following: --Keys link forward and backward to other taxonomic levels. --Plate references in taxonomic treatments link to plates for rapid reference. --Plate captions link to taxonomic treatments. --Individual taxon figures appear next to species descriptions, and full plates are gathered in a special section. --Glossary terms link to any relevant illustrations. --List of families links each family to its taxonomic treatment. --Index is fully linked to taxonomic treatments.

    Notes: Abstract Various plants native to arid and semiarid habitats throughout the southwestern United States, Baja California, and northern Mexico were bioassayed for phototoxic natural products. Approximately 115 species representing 57 genera and eight plant families were assayed for phototoxic activity by standard antimicrobial techniques usingEscherichia coli andSaccharomyces cerevisiae. Phototoxic constituents were extracted from numerous members in the Asteraceae (Compositae) and occurred with highest frequency among species of the subtribe Pectidinae (tribe Heliantheae). Extracts ofPectis, the largest genus in the Pectidinae, had substantial light-activated biocidal action despite the paucity of acetylenic thiophenes, the phototoxins characteristic of most other genera in the subtribe. Leaf resin from the creosote bush [Larrea tridentata (Sesse & Mol. ex DC.) Coville; Zygophyllaceae], a dominant desert shrub, possessed potent antimicrobial activity in the absence of light; however, the toxicity of this extract was slightly enhanced in the presence of UVA irradiation. Phototoxic antimicrobials were not detected in extracts of selected species from the Asclepiadaceae, Chenopodiaceae, Hydrophyllaceae, Lamiaceae, Polygonaceae, or Solanaceae.

    In:  Supplement to: Miller, Kenneth G; Janecek, Thomas R; Katz, Miriam E; Keil, David J (1987): Abyssal circulation and benthic foraminiferal changes near the Paleocene/Eocene boundary. Paleoceanography, 2(6), 741-761, https://doi.org/10.1029/PA002i006p00741

    Description: A major change in Cenozoic deep-sea benthic foraminifera occurred in the Atlantic, Indian, and Pacific oceans near the Paleocene/Eocene boundary. Benthic foraminiferal abundance changes began at about 61.5 Ma at Pacific Deep Sea Drilling Project (DSDP) Site 577. A major extinction event followed at 58-57 Ma (between Zones P6a and P6b), and a series of first appearances continued until circa 55.5 Ma (Zone P6c). These faunal changes occurred during a 6°C warming of Pacific bottom water and may indicate that the primary cause was changing temperature. Other potential causes of the faunal turnover include global changes in surface ocean productivity and changing bottom water source regions. Comparison of benthic and planktonic delta13C records requires no change in the ratio of oceanic phosphorous to carbon during the late Paleocene to early Eocene, which weakens the case for (but does not disprove) a change in surface ocean productivity at this time. Interbasinal comparisons of benthic foraminiferal delta13C records document that water with high delta13C values filled the Cape Basin during the late Paleocene and possibly the early Eocene (circa 61-57 Ma), but apparently did not extend into the western basins of the Atlantic. This pattern suggests a supply of Antarctic source water for the Cape Basin and possible tectonic isolation of the western Atlantic basins during at least part of the late Paleocene. Carbon isotope comparisons show that bottom water supply to the Cape Basin was reduced in the early Eocene. Eolian grain size data suggest that a decrease in zonal wind intensity occurred at the end of the Paleocene. These late Paleocene climatic changes (bottom water warming and decreased wind intensity) correspond with evidence for an important global tectonic reorganization and extensive subaerial volcanism, which may have contributed to climatic warming through increased supply of CO2.
