Islandica

This volume sheds new light on the marine fauna and geological setting of the Tjörnes Sequence, North Iceland, which is a classic site for the Pliocene and Pleistocene stratigraphy of the North Atlantic region. Readers will discover descriptions of new data collected by the editors over a period of over three decades on marine faunal assemblages and sedimentology available for palaeoenvironmental reconstructions, as well as the tectonic and stratigraphical relationships on Tjörnes Peninsula. The book includes a comprehensive account of all the collections of marine fossil invertebrate macrofossils and foraminifera known to the editors from the Tjörnes Sequence. It is expected to elucidate sedimentological and faunal changes from relatively stable Pliocene conditions to highly variable and periodically harsh climatic conditions of recurring Quaternary glaciations. The distribution, recent or fossil, of various species is recorded and pertinent ecological and biological features are also discussed. The Tjörnes Sequence records the Neogene migration of Pacific species into the North Atlantic. Researchers in geology, climate science, environmental science and earth science will find this book particularly valuable.

This eighth volume in the comprehensive Illustrated Flora of Illinois series is the seventh volume devoted to flowering plants (the eighth volume is devoted to ferns) and the second treating dicotyledons, which include such well-known plants as roses, peas, mustards, mints, nightshades, milkweeds, and asters. The previous volume on dicots, Flowering Plants: Hollies to Loasas, was published in 1978. In the present volume, Mohlenbrock includes three orders of vascular plants encompassing five families. The orders are Salicales and Tamaricales, of the Salicaceae and Tamaricaceae families, and Capparidales, of the Capparidaceae, Resedaceae, and Brassicaceae families. In all, 44 genera and 117species are treated in this volume, each species illustrated in detail.
