This illustrated introduction to Central American Chironomidae offers extensive photographic material, as well as detailed morphological and ecological descriptions of chironomid subfossils found in Central American lake sediments. The book uniquely provides two identification keys: one for living larvae occurring (or potentially being present) in Central America and one for the recorded subfossil remains, using limited morphological characters. Paleolimnological investigations using chironomid remains have undergone a resurgence of interest, and this taxonomic guide will aid the thorough analysis of the diversity and distribution of the taxa encountered to date in Central America. Out of the total 64 described genera, the book brings 20 endemic genera, and more than half of the presented morphotypes are new. Plates are included for each taxon with generic characters and also provide a key to morphotypes, if present, their specific characters, distribution, and ecology. Authored by a (paleo)limnologist and a taxonomist, the guide draws on a thorough taxonomical knowledge of the region's recent chironomid fauna. It uses a paleolimnological approach to transmit this information to morphotypes that can be linked with ecology and used to reconstruct the past development of nature. The book thus helps paleo-workers and taxonomists to learn more about these fascinating insects and, through them, to discover the world around us. Providing a comprehensive reference for aquatic ecologists, paleolimnologists, students, and researchers, the guide will also be of interest to non-academic professionals working on applied research and biomonitoring of lakes. It will be useful for people studying both recent and subfossil material, not only in Central America, but in the whole Neotropical region.

The chapters in this book will cover the paleontology and geology of some important rock formations (Paleozoic and Paleogene) in the northeastern United States. The emphasis will be on brachiopod paleontology, specifically taxonomy, but will also include comments on morphologic variation and community analysis. The Martinsburg formation in the lower mid-Hudson Valley has been studied for many years but recently yielded numerous marine fossils that shed new light on the community ecology of the formation in the region. The Middle Silurian Shawangunk Formation near New Paltz, New York, is an important ridge-maker that extends toward the southwest into Pennsylvania. Recently discovered rare trace fossils in the Shawangunk will be discussed along with the depositional environment of the conglomerate. The Onondaga Limestone is a well-known formation that crops out from Port Jervis, northeast toward Albany and the westward to Buffalo. The brachiopods and community structure of the formation will be covered in some detail. The paleoecology of the Paleogene Hornerstown Formation of New Jersey will also be discussed, including a biostrome of large terebratulid brachiopods.

This textbook introduces research on dinosaurs by describing the science behind how we know what we know about dinosaurs. A wide range of topics is covered, from fossils and taphonomy to dinosaur physiology, evolution, and extinction. In addition, sedimentology, paleo-tectonics, and non-dinosaurian Mesozoic life are discussed. There is a special opportunity to capitalize on the enthusiasm for dinosaurs that students bring to classrooms to foster a deeper engagement in all sciences. Students are encouraged to synthesize information, employ critical thinking, construct hypotheses, devise methods to test these hypotheses, and come to new defensible conclusions, just as paleontologists do. Key Features Clear and easy to read dinosaur text with well-defined terminology Over 600 images and diagrams to illustrate concepts and aid learning Reading objectives for each chapter section to guide conceptual learning and encourage active reading Companion website (teachingdinosaurs.com) that includes supporting materials such as in-class activities, question banks, lists of suggested specimens, and more to encourage student participation and active learning Ending each chapter with a specific "What We Don't Know" section to encourage student curiosity Related Titles Singer, R.

Although it is generally accepted that the Arctic Ocean is a very sensitive and important region for changes in the global climate, this region is the last major physiographic province of the earth whose short-and long-term geological history is much less known in comparison to other ocean regions. This lack of knowledge is mainly caused by the major technological/logistic problems in reaching this harsh, ice-covered region with normal research vessels and in retrieving long and undisturbed sediment cores. During the the last about 20 years, however, several international and multidisciplinary ship expeditions, including the first scientific drilling on Lomonosov Ridge in 2004, a break-through in Arctic research, were carried out into the central Artic and its surrounding shelf seas. Results from these expeditions have greatly advanced our knowledge on Arctic Ocean paleoenvironments.
Published syntheses about the knowledge on Arctic Ocean geology, on the other hand, are based on data available prior to 1990. A comprehensive compilation of data on Arctic Ocean paleoenvironment and its short-and long-term variability based on the huge amount of new data including the ACEX drilling data, has not been available yet. With this book, presenting (1) detailed information on glacio-marine sedimentary processes and geological proxies used for paleoenvironmental reconstructions, and (2) detailed geological data on modern environments, Quaternary variability on different time scales as well as the long-term climate history during Mesozoic-Tertiary times, this gap in knowledge will be filled.

The present volume is the first in a series of two books dedicated to the paleoceanography of the Late Cenozoic ocean. The need for an updated synthesis on paleoceanographic science is urgent, owing to the huge and very diversified progress made in this domain during the last decade. In addition, no comprehensive monography still exists in this domain. This is quite incomprehensible in view of the contribution of paleoceanographic research to our present understanding of the dynamics of the climate-ocean system. The focus on the Late Cenozoic ocean responds to two constraints. Firstly, most quantitative methods, notably those based on micropaleontological approaches, cannot be used back in time beyond a few million years at most. Secondly, the last few million years, with their strong climate oscillations, show specific high frequency changes of the ocean with a relatively reduced influcence of tectonics. The first volume addresses quantitative methodologies to reconstruct the dynamics of the ocean andthe second, major aspects of the ocean system (thermohaline circulation, carbon cycle, productivity, sea level etc.) and will also present regional synthesis about the paleoceanography of major the oceanic basins. In both cases, the focus is the "open ocean" leaving aside nearshore processes that depend too much onlocal conditions. In this first volume, we have gathered up-to-date methodologies for the measurement and quantitative interpretation of tracers and proxies in deep sea sediments that allow reconstruction of a few key past-properties of the ocean( temperature, salinity, sea-ice cover, seasonal gradients, pH, ventilation, oceanic currents, thermohaline circulation, andpaleoproductivity). Chapters encompass physical methods (conventional grain-size studies, tomodensitometry, magnetic and mineralogical properties), most current biological proxies (planktic and benthic foraminifers, deep sea corals, diatoms, coccoliths, dinocysts and biomarkers) and key geochemical tracers (trace elements, stable isotopes, radiogenic isotopes, and U-series). Contributors to the book and members of the review panel are among the best scientists in their specialty. They represent major European and North American laboratories and thus provide a priori guarantees to the quality and updat of the entire book. Scientists and graduate students in paleoclimatology, paleoceanography, climate modeling, and undergraduate and graduate students in marine geology represent the target audience. This volume should be of interest for scientists involved in several international programs, such as those linked to the IPCC (IODP - Integrated Ocean Drilling Program; PAGES - Past Global Changes; IMAGES - Marine Global Changes; PMIP: Paleoclimate Intercomparison Project; several IGCP projects etc.), That is, all programs that require access to time series illustrating changes in the climate-ocean system.
* Presents updated techniques and methods in paleoceanography
* Reviews the state-of-the-art interpretation of proxies used for quantitative reconstruction of the climate-ocean system
* Acts as a supplement for undergraduate and graduate courses in paleoceanography and marine geology

All of man's life is in some way associated with the plant world, from his food and shelter to his art, religion and language. The study of this all-pervading relationship between man and the plant world is called "ethnobotany." This book provides a systematic reconstruction of the ethnobotany of one of the hearths of American civilization, in the prehistoric cultures of the Peruvian Central Andes.

As we learn more about the rise and spread of New World agriculture, it becomes evident that Peru was one of the sources of its development. Plants were cultivated here at least 2,000 years before the beginning of the Christian era. Village life was intimately bound up with this cultivation, later civilizations rested upon it as a foundation, and from Peru agriculture was diffused to other parts of the Americas.

Towle bases her work on the evidence of plant remains found in archeological sites, surveys of botanical and ethnological literature, and field studies of modern plant utilization. After a methodological and historical introduction, she proceeds to a systematic listing of plant species, each fully described. She then presents the ethnobotanical data for each of the cultural-geographic divisions of the area, giving a chronological picture of the use of wild and cultivated plants against a background of the cultures of which they were part. A summary of the evolutionary trends in the region as a whole is followed by a full bibliography and index. The book contains fifteen pages of plates.

"Margaret A. Towle" (1902-1985) received her doctorate from Columbia University in 1958 and was research fellow in ethnobotany in the Botanical Museum of Harvard University.

Every day, in natural history museums all across the country, colonies of dermestid beetles diligently devour the decaying flesh off of animal skeletons that are destined for the museum's specimen collection. That time-saving process was developed and perfected at the University of Kansas Natural History Museum by Charles D. Bunker, a lowly assistant taxidermist who would rise to become the curator of recent vertebrates and who made an indelible mark on his field. That innovative breakthrough serves as a testament to the tenacity of a quietly determined naturalist. Bunker was part of the small team of men who constructed and installed the famous Panorama of North American Mammals, the centerpiece exhibit of the KU Natural History Museum located in Dyche Hall. That iconic building on the KU campus was expressly built to house the collection of mounted animals that impressed the world a decade earlier at the 1893 Chicago Columbian Exposition and World's Fair. Once the panorama was completed, Bunker turned his attention to field collecting. Bunker's field notes provide an accurate, authentic account of several expeditions to collect such specimens as well as a rare view of the extreme hardships of fieldwork in those early days. Perhaps most notable is “Bunk's” 1911 expedition to western Kansas, where he discovered the fossil remains of a forty-five-foot-long sea serpent—later identified as Tylosaurus proriger, an aquatic reptile from the mosasaur genus and the largest example of the species found in North America. In 2014, Tylosaurus was named the marine fossil of the state of Kansas. Birds, Bones, and Beetles tells the story of a man whose passion for learning led to remarkable discoveries, extraordinary exhibits, and the prestigious careers of many students he mentored in the natural sciences.

Understanding Fossils is the first introductory level palaeontology text which demonstrates the importance of fossils in geological and biological studies, particularly in understanding evolutionary patterns, palaeoenvironmental analysis, and stratigraphy. The book contains three parts. Part One explores several key concepts: the processes of fossil preservation, the determination of evolutionary patterns, ancient ecologies and use of fossils as stratigraphical tools. Part Two introduces the main fossil groups of value in these applied fields. Each group is described with reference to their most important characters, and each has summaries of classification, evolutionary history and applications. Part Three concentrates on the examination of important case histories which demonstrate the use of fossils in diverse practical examples. Evolutionary studies, palaeoenvironmental analysis and stratigraphical applications are documented using up-to-date examples supported by overviews of the principles.

This book serves as an up-to-date introduction, as well as overview to modern trace fossil research and covers nearly all of the essential aspects of modern ichnology. Divided into three section, Trace Fossils covers the historical background and concepts of ichnology, on-going research problems, and indications about the possible future growth of the discipline and potential connections to other fields. This work is intended for a broad audience of geological and biological scientists. Workers new to the field could get a sense of the main concepts of ichnology and a clear idea of how trace fossil research is conducted. Scientists in related disciplines could find potential uses for trace fossils in their fields. And, established workers could use the book to check on the progress of their particular brand of ichnology. By design, there is something here for novice and veteran, insider and outsider, and for the biologically-oriented workers and for the sedimentary geologists.
* Presents a review of the state of ichnology at the beginning of the 21st Century
* Summarizes the basic concepts and methods of modern trace fossil research
* Discusses crucial background information about the history of trace fossil research, the main concepts of ichnology, examples of current problems and future directions, and the potential connections to other disciplines within both biology and geology

The phylum Mollusca is the second largest group of animals and occur in virtually all habitats. Many non-marine molluscs are threatened with more recorded extinctions than all tetrapod vertebrates combined. This two-volume set will provide the first general account of molluscs in decades and will include hundreds of colour figures. General chapters bring together a diverse and extensive literature, while taxon chapters provide overviews of their evolution, phylogeny and classification as well as more specific and detailed coverage of their biology (reproduction, feeding and digestion, excretion, respiration etc.), their long fossil record, and their natural history.

The Late Devonian and Permian-Triassic intervals are among the most dynamic episodes of Earth history, marked by large secular changes in continental ecosystems, dramatic fluctuations in ocean oxygenation, major phases of biotic turnover, volcanism, bolide impact events, and rapid fluctuations in stable isotope systems and sea level. This volume highlights contributions from a broad range of geological sub-disciplines currently striving to understand these critical intervals of geologically rapid, global-scale changes.
* Provides updated, current models for the mid-Late Devonian and Permian-Triassic mass extinction episodes
* Highlights several new analytical approaches for developing quantitative
datasets
* Takes an integrated approach presenting datasets from a broad range of sub-disciplines

There is only one kind of human on earth today: us. But we are only one of a number of human species - primates of the Hominini tribe - that have existed on our planet across the millennia. In 2004 the world was astounded by the discovery of Homo floresiensis, a species of human never encountered before, on the island of Flores in the Indonesian archipelago. A very short, thickset being, with long arms and feet and an appetite for stegodons (a now extinct relative of modern elephants), it was soon nicknamed 'the hobbit'. As recently as 52,500 years ago, at a time when our own ancestors were spreading around the world, these 'hobbit' cousins lived also, at least on Flores. In Little Species, Big Mystery archaeologist Debbie Argue takes us on a journey of thrilling scientific discovery, recounting the unearthing of H. floresiensis, the archaeological expeditions that have followed, other finds - including that of a small Philippines hominin - and new paths of research and discussion. Argue conveys the excitement of searching for and finding clues to a lost past, and the animated discussions that have flowed from their discovery. She provides much contextual information to strengthen our grasp of the essential coordinates of this field and stimulate our interest in the shadowy, fascinating realm of prerecorded time.

In this deep examination of functional morphology, a renowned paleoanthropologist offers a new way to investigate human evolution through the fossil record. It is common for two functional anatomists to examine the exact same fossil material, yet argue over its evolutionary significance. How can this be? Traditionally, paleoanthropology has interpreted hominin fossil morphology by first considering the ecological challenges hominins faced, then drawing adaptive inferences based on the idea that skeletal morphology is largely a reflection of paleoecology. In Functional Inference in Paleoanthropology, innovative paleoanthropologist David J. Daegling suggests that researchers can resolve dichotomous interpretations of the fossil record by instead focusing on the biology and development of the bones themselves-such as measurable responses to deformations, stresses, and damage. Critically exploring how scientists probe and interpret fossil morphology for behavioral and adaptive inferences, Daegling makes the case that an intelligible science of functional morphology in the fossil record is impossible without the inclusion of this mechanobiological perspective. Drawing on historical examples from long-standing debates on the emergence of bipedality and the dietary shifts that facilitated the emergence of the hominin clade, Daegling traces the disjunctions between theoretical principles of comparative morphology and methodological practice in the paleontological context of human evolution. Sharing rich findings from recent decades of research in skeletal biomechanics, Functional Inference in Paleoanthropology examines how bone adapts over the lifespan, what environmental factors influence its quality, and how developmental constraints limit the skeleton's adaptive potential over evolutionary time.

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in virtually all habitats. Some are commercially important, a few are pests and some carry diseases, while many non-marine molluscs are threatened by human impacts which have resulted in more extinctions than all tetrapod vertebrates combined. This book and its companion volume provide the first comprehensive account of the Mollusca in decades. Illustrated with hundreds of colour figures, it reviews molluscan biology, genomics, anatomy, physiology, fossil history, phylogeny and classification. This volume includes general chapters drawn from extensive and diverse literature on the anatomy and physiology of their structure, movement, reproduction, feeding, digestion, excretion, respiration, nervous system and sense organs. Other chapters review the natural history (including ecology) of molluscs, their interactions with humans, and assess research on the group. Key features of both volumes: up to date treatment with an extensive bibliography; thoroughly examines the current understanding of molluscan anatomy, physiology and development; reviews fossil history and phylogenetics; overviews ecology and economic values; and summarises research activity and suggests future directions for investigation. Winston F Ponder was a Principal Research Scientist at The Australian Museum in Sydney where he is currently a Research Fellow. He has published extensively over the last 55 years on the systematics, evolution, biology and conservation of marine and freshwater molluscs, as well as supervised post graduate students and run university courses. David R. Lindberg is former Chair of the Department of Integrative Biology, Director of the Museum of Paleontology, and Chair of the Berkeley Natural History Museums, all at the University of California. He has conducted research on the evolutionary history of marine organisms and their habitats on the rocky shores of the Pacific Rim for more than 40 years. The numerous elegant and interpretive illustrations were produced by Juliet Ponder.

Originally published in 1987 Rates of Evolution is an edited collection drawn from a symposium convened to bring together palaeontologists, geneticists, molecular biologists and developmental biologists to examine some aspects of the problem of evolutionary rates. The book asks questions surrounding the study of evolution, such as did large morphological changes really occur rapidly at various times in the geological past, or is the fossil record too imperfect to be of value in assessing rates of morphological change? What is the measure of 'rapid' change? Is stasis at any taxonomic level established? Is it possible to relate genomic and morphological change? What is the role of regulatory and executive genes in controlling evolutionary change? Does the transfer of genetic material between different taxa provide the possibility of increasing evolutionary rates? Featuring contributions from leading researchers, this book will interest anthropologists, palaeontology and scientists of evolution and genetics.

Originally published in 1915, The Natural Theology of Evolution looks at the concept of natural theology, examining the argument for the existence of God based on reason and ordinary experiences of nature. The book looks at natural theology in light of Darwin's theory of evolution, and how this important discovery affected belief in intelligent design. The book argues that the discovery of evolution, far from diminishing the existence of God, provides stronger proof for an intelligently designed earth and therefore the existence of God. This book provides a unique and interesting take on the debates surrounding evolution in the late 19th and early 20th century. It will be of interest to philosophers, historians of religion and natural historians alike.

Originally published in 1987, Human Evolution looks at theories of the evolution of human behaviour (contemporary at the time of publication). The book reviews competing theories of psychological and social evolution and provides a detailed historical introduction to the subject. A key theoretical concern which emerges in the book includes the psychological significance of the human evolution issue itself. The period of human evolution covered ranges from the demise of the Miocene hominoids, to the emergence of 'civilization'. Topics covered include: functions of 'origin myths', history of the study of human evolution, methods and data-bases, theories of the nature of 'hominisation', origins of bipedalism, language and tool-use, theories of social evolution, theories of cave art and the spread of Homo sapiens to America and Australia.

Originally published in 1933 Functional Affinities of Man, Monkeys and Apes gives a taxonomic and phylogenetic survey and the findings of diverse experimental investigations of lemurs, monkeys, and apes. The book discusses the inter-relationships of different Primates and emphasizes seldom-used approaches to the question of primate phylogeny. The book attempts to show how little they have been systematically tried, and argues for a regard to the proper place of functional investigations in the study of the classification and evolution of Primates. This book will be of interest to anthropologists, scientists and historians alike.

This volume is an outcome of the 12th international conference of the international bryozoology association in Dublin. It consists of 85 oral and 16 poster presentations which cover all aspects of bryozoological research.

ANOXIA defines the lack of free molecular oxygen in an environment. In the presence of organic matter, anaerobic prokaryotes produce compounds such as free radicals, hydrogen sulfide, or methane that are typically toxic to aerobes. The concomitance of suppressed respiration and presence of toxic substances suggests these habitats are inhospitable to Eukaryota. Ecologists sometimes term such environments 'Death Zones'. This book presents, however, a collection of remarkable adaptations to anoxia, observed in Eukaryotes such as protists, animals, plants and fungi. Case studies provide evidence for controlled beneficial use of anoxia by, for example, modification of free radicals, use of alternative electron donors for anaerobic metabolic pathways, and employment of anaerobic symbionts. The complex, interwoven existence of oxic and anoxic conditions in space and time is also highlighted as is the idea that eukaryotic inhabitation of anoxic habitats was established early in Earth history.

This multidisciplinary book focuses on the relationships and interactions between palaeobiogeography, biogeography, dispersal, vicariance, migrations and evolution of organisms in the SE Asia-Australasian region. The book investigates biogeographic links between SE Asia and Australasia which go back more than 500 million years. It also focuses on the links between geological evolution and biological migrations and evolution in the region. It was in the SE Asian region that Alfred Russell Wallace established his biogeographic line, now known as Wallace's Line, which was the beginning of biogeography. Wallace also independently developed his theory of evolution based on his work in this area.;The book brings together, for the first time, geologists, palaeontologists, zoologists, botanists, entomologists, evolutionary biologists and archaeologists, in the one volume, to relate the region's geological past to its present biological peculiarities. The book is organized into six sections. Section 1 Paleobiogeographic Background provides overviews of the geological and tectonic evolution of SE Asia-Australasia, and changing patterns of land and sea for the last 540 million years. Section 2 Palaeozoic and Mesozoic Geology and Biogeography discusses Palaeozoic and Mesozoic biogeography of conodonts, brachiopods, plants, dinosaurs and radiolarians and the recognition of ancient biogeographic boundaries or Wallace Lines in the region. Section 3 Wallace's Line focuses on the biogeographic boundary established by Wallace, including the history of its establishment, its significance to biogeography in general and its applicability in the context of modern biogeography.;Section 4 Plant biogeography and evolution includes discussion on primitive angiosperms, the diaspora of the southern rushes, and environmental, climatic and evolutionary implications of plants and palynomorphs in the region. The biogeography and migration of insects, butterflies, birds, rodents and other non-primate mammals is discussed in section 5, Non Primates. The final section 6 Primates focuses on the biogeographic radiation, migration and evolution of primates and includes papers on the occurrence and migration of early hominids and the requirements for human colonization of Australia.

This impeccably-researched volume skillfully reports and discusses advances in phytolith research, addressing in particular the use of phytoliths for deciphering fundamental issues in earth science and human history. Comprising thirty reviews and original papers, findings are presented in the following five sections:
A- phytoliths in palaeoclimatology and palaeoecology
A- phytoliths, diet and health
A- archaeological structures, ancient agricultures and palaeoethnobotany
A- methodology, taxonomy and taphonomy
A- soil-plant interaction.

The Great Ice Age documents and explains the natural climatic and palaeoecologic changes that have occurred during the past 2.6 million years, outlining the emergence and global impact of our species during this period. Exploring a wide range of records of climate change, the authors demonstrate the interconnectivity of the components of the Earths climate system, show how the evidence for such change is obtained, and explain some of the problems in collecting and dating proxy climate data.
One of the most dramatic aspects of humanity's rise is that it coincided with the beginnings of major environmental changes and a mass extinction that has the pace, and maybe magnitude, of those in the far-off past that stemmed from climate, geological and occasionally extraterrestrial events. This book reveals that anthropogenic effects on the world are not merely modern matters but date back perhaps a million years or more.
