Book Description
Phytolith studies are placed in the interaction of many scientific fields in both natural and human sciences. Although phytolith studies go back over 150 years, in the last 20 years they have increased substantially, with many publications in scientific journals of recognised quality. This book presents a review and synthesis of recent works in some areas of the Southeast and Southern Brazil and the Pampean Plain in Argentina, which have concentrated on numerous phytolith studies and may provide new contributions to the knowledge of phytoliths in these regions. This book has eleven chapters structured in sections. As an introduction a review of phytolith production and functions, organ and tissue localisation and distribution among plant families is presented. It also describes the main phytolith morphologies found in plants, soils and sediments and their taxon assignment. The taxonomic value of these amorphous silica biomineralisations and the classifications employed in different phytolith studies are also discussed. A summary of some phytolith indexes, used in palaeoenvironmental studies from different regions and based on the relative abundances of morphologies, is presented. Lastly, applications and limitations of phytolith studies are also mentioned.

Book Description
This volume focuses on the reconstruction of past ecosystems and provides a comprehensive review of current techniques and their application in exemplar studies. The 18 chapters address a wide variety of topics that span vertebrate paleobiology and paleoecology (body mass, postcranial functional morphology, evolutionary dental morphology, microwear and mesowear, ecomorphology, mammal community structure analysis), contextual paleoenvironmental studies (paleosols and sedimentology, ichnofossils, pollen, phytoliths, plant macrofossils), and special techniques (bone microstructure, biomineral isotopes, inorganic isotopes, 3-D morphometrics, and ecometric modeling). A final chapter discusses how to integrate results of these studies with taphonomic data in order to more accurately characterize an ancient ecosystem. Current investigators, advanced undergraduates, and graduate students interested in the field of paleoecology will find this book immensely useful. The length and structure of the volume also makes it suitable for teaching a college-level course on reconstructing Cenozoic ecosystems.

Book Description
Peatlands are transition ecosystems between terrestrial and aquatic environments, formed by the accumulation in time and space of plant tissues under conditions of excessive humidity, low nutrient availability, low pH and oxygen scarcity, where organic matter undergoes slow humification processes. The peatland ecosystems of the Southern Espinhaço Mountain Range, located in Minas Gerais State, Brazil, were formed by the sui generis combination of environmental factors, source of its great biodiversity, endemic and peculiar. For thousands of years these ecosystems have been developing, preserving proxies for environmental reconstitution, sequestering more and more carbon and increasing their capacity to store water ("sponge effect") and regulate the flow of water courses. Environmental reconstitution studies carried out in these ecosystems have evidenced several regional paleoclimatic changes in the last 35 thousand years. The stock of sequestered carbon is 4,877,840 tons and 142,138,262 m3 of water are stored in 14,288 ha of these peatlands. These ecosystems constitute the headwaters of rivers in the most important basins in eastern Brazil: the São Francisco, Jequitinhonha and Doce river basins and regulate their flow during the dry period of the year. However, peatlands located outside protected areas are threatened by anthropization. The Long-Term Ecological Research Program "Peatlands of the Southern Espinhaço Mountain Range: ecosystem services and biodiversity" – PELD TURF (fund: CNPq and FAPEMIG), started in 2021, intensified the characterization and monitoring of the biodiversity and ecosystem services of these peatlands. The results of two decades of research revealed the importance of these ecosystems for biodiversity, for the global carbon cycle, for regional water resources and for paleoenvironmental reconstitution. It was also evident that the rapid degradation of these ecosystems, caused mainly by anthropization, can irreversibly compromise, in the medium term, their ecosystem services, biodiversity and paleoenvironmental reconstitution studies. Thus, it is urgent to empower local and regional communities about the importance of peatland ecosystems both for the environment, for the socio-economy and for the quality of life of their populations, as well as for the planet.

Book Description
This volume is the first in theAdvances in Archaeological and Museum Science series sponsored by the Society for Archaeological Sciences. The purpose of this biennial series is to provide summaries of advances in closely defined topics in archaeometry, archaeological science, environmental archaeology, preservation technology and museum conservation. The Society for Archaeological Sciences (SAS) exists to encourage interdisci plinary collaboration between archaeologists and colleagues in the natural and physical sciences. SAS members are drawn from many disciplinary fields. However, they all share a common belief that physical science techniques and methods constitute an essential component of archaeological field and laboratory studies. The General Editors wish to express their appreciation to Renee S. Kra and Frances D. Moskovitz of Radiocarbon for their special expertise and assistance in the production of this volume. We also appreciate the contribution of the two reviewers for their excellent comments and suggestions. The General Editor responsible for undertaking the development of this volume was R. E. Taylor.

Book Description
The first edition of my book "Climate and Circulation of the Tropics" was reasonably up to date to the middle of 1985. In a second printing in 1988 it was possible to complete a few literature references and to correct some misprints. However, vigorous research has taken place over the past five years in various areas of tropical climate dynamics, especially in the atmosphere-ocean mechanisms of climate anomalies, climate prediction, ocean circulation, and paleoclimates. Promising progress has also been made in the application of general circulation modelling to tropical climate problems. In the present second edition, named "Climate Dynamics of the Tropics", I have attempted to incorporate much of the recent work to late 1990. Chapters 8 and 9 have been essentially re-written, and major additions have been made to Chapters 4 and 12 in particular. I would like to acknowledge the continued support by the U.S. National Science Foundation over the past five years. B. Parthasarathy, Poona, and H. Lessmann, San Salvador, sent me updates of data series not easily accessible. I have benefitted from discussions with numerous colleagues in the United States and overseas. In the preparation of this second edition, Marilyn Wolff patiently transferred my illegible hand-written drafts onto word processor. Dierk Polzin and Dan Skemp assisted me with the creation of the page masters and the subject index and Christopher Collimore with the author index.

Book Description
This pioneering and comprehensive survey is the first overview of current themes in Latin American archaeology written solely by academics native to the region, and it makes their collected expertise available to an English-speaking audience for the first time. The contributors cover the most significant issues in the archaeology of Latin America, such as the domestication of camelids, the emergence of urban society in Mesoamerica, the frontier of the Inca empire, and the relatively little known archaeology of the Amazon basin. This book draws together key areas of research in Latin American archaeological thought into a coherent whole; no other volume on this area has ever dealt with such a diverse range of subjects, and some of the countries examined have never before been the subject of a regional study.

Book Description
This book will help beekeepers understand the fundamentals of beekeeping science. Written in plain and accessible language by actual researchers, it should be part of every beekeeper’s library. The respective chapters not only present raw data; they also explain how to read and understand the most common figures. With topics ranging from honeybee nutrition to strains of Varroa resistant bees, from the effects of pesticide chemicals to understanding diseases, and including a discussion of venom allergies, the book provides essential “knowhow” that beekeepers will benefit from every time they inspect their hives. Further, each chapter ends with the author explaining how beekeepers can (or cannot) directly utilize the information to enhance their beekeeping operation. The text is structured to facilitate ease of use, with each author addressing the same four issues: 1) What are the specific purposes or goals of these experiments? Or more simply: what have these studies taught us? 2) How should a non-scientist read the data generated? 3) What are the key points in relation to practicing beekeepers’ goals? 4) How can the data or techniques discussed be applied by beekeepers in their own apiaries? This approach allows readers to look up specific information quickly, understand it and even put it to use without having to read entire chapters. Further, the chapters are highly readable and concise. As such, the book offers a valuable guide and faithful companion for all beekeepers, one they can use day in and day out.
