Elements of Paleontology

Nebelsick James H.: The Taphonomy of
Echinoids

The Taphonomy of Echinoids

Skeletal Morphologies, Environmental Factors, and Preservation Pathways

"This Element reviews the ecologies of skeletal trace-producing interactions on echinoids in modern ecosystems and the recognition of those biogenic traces in the fossil record. This title is also available as Open Access on Cambridge Core"--

Modern Insights into Ancient Interactions

The Ecology of Biotic Interactions in Echinoids

The extraxial-axial theory (EAT) and universal elemental homology (UEH) are often portrayed as mutually exclusive hypotheses of homology within pentaradiate Echinodermata. EAT describes homology upon the echinoderm bauplan, interpreted through early post-metamorphic growth and growth zones, dividing it into axial regions generally associated with elements of the ambulacral system and extraxial regions that are not. UEH describes the detailed construction of the axial skeleton, dividing it into homologous plates and plate series based on symmetry, early growth, and function. These hypotheses are not in conflict; the latter is rooted in refinement of the former. Some interpretive differences arise because many of the morphologies described from eleutherozoan development are difficult to reconcile with Paleozoic forms. Conversely, many elements described for Paleozoic taxa by UEH, such as the peristomial border plates, are absent in eleutherozoans. This Element recommends these two hypotheses be used together to generate a better understanding of homology across Echinodermata.

A Review and Evaluation of Homology Hypotheses in Echinoderm Paleobiology

Echinoderms have evolved diverse and disparate morphologies throughout the Phanerozoic. Among them, blastozoans, an extinct group of echinoderms that were an important component of Paleozoic marine ecosystems, are primarily subdivided into groups based on the morphology of respiratory structures. However, systematic and phylogenetic research from the past few decades have shown that respiratory structures in blastozoans are not group-defining and they have re-evolved throughout echinoderm evolution. This Element provides a review of the research involving blastozoan respiratory structures, along with research concerning the morphology, paleoecology, and ontogeny of each of the major groupings of blastozoans as it relates to their corresponding respiratory structures. Areas of future research in these groups are also highlighted.

A Review of Blastozoan Echinoderm Respiratory Structures

The echinoderms are an ideal group to understand evolution from a holistic, interdisciplinary framework. The genetic regulatory networks underpinning development in echinoderms are some of the best known for any model group. Additionally, the echinoderms have an excellent fossil record, elucidating in in detail the evolutionary changes underpinning morphological evolution. In this Element, the echinoderms are discussed as a model group for molecular palaeobiological studies, integrating what is known of their development, genomes, and fossil record. Together, these insights shed light on the molecular and morphological evolution underpinning the vast biodiversity of echinoderms, and the animal kingdom more generally.

Molecular Paleobiology of the Echinoderm Skeleton

Fossil crinoids are exceptionally suited to deep-time studies of community paleoecology and niche partitioning. By merging ecomorphological trait and phylogenetic data, this Element summarizes niche occupation and community paleoecology of crinoids from the Bromide fauna of Oklahoma (Sandbian, Upper Ordovician).

Phylogenetic comparative methods (PCMs) provide paleontologists with analaytical tools for investigating evolutionary tempo and mode in fossil lineages, but integrating them with fossil data can be challenging. This Element presents guides to applying PCMs with fossil taxa as well as example analayses illustrating common applications.

The Encyclopedia of Lipidomics will present a complete overview of the field from fundamentals to new discoveries and from concepts, theories and experimental techniques to clinical and industrial applications. The book will develop with the active involvement of a strong editorial board comprised of leaders from the field. The Encyclopedia of Lipidomics intends to be a comprehensive reference resource serving to bridge the gap between clinical and basic science investigators and provide authoritative and digested information to students, scientists as well as non specialists. The book will have an edge over protocol type of works and databases in terms of having wider coverage through rigorous essays on terms, concepts, experimental and analytical techniques, applications and new challenges. Since lipidomics has strong linkages with several of the other biomedical and life sciences disciplines, the proposed encyclopedia will have a wide audience including graduate students, researchers and different levels of scientists in biomedicine, cellular and molecular biology, bioengineering, physiological and biochemistry, and pharmacology across both academia and industry.

From a New York Times bestselling nature writer comes a celebration of what goes on outside in the dark, from blooming moon gardens to nocturnal salamanders, from glowing foxfire and synchronous fireflies that blink in unison like an orchestra of light. In this glorious celebration of the night, New York Times bestselling nature writer Leigh Ann Henion invites us to leave our well-lit homes, step outside, and embrace the dark as a profoundly beautiful part of the world we inhabit. Because no matter where we live, we are surrounded by animals that rise with the moon, and blooms that reveal themselves as light fades. Henion explores her home region of Appalachia, where she attends a synchronous firefly event in Tennessee, a bat outing in Alabama, and a moth festival in Ohio. In North Carolina, she finds forests alight with bioluminescent mushrooms, neighborhood trees full of screech owls, and valleys teeming with migratory salamanders. Along the way, Henion encounters naturalists, biologists, primitive-skills experts, and others who've dedicated their lives to cultivating relationships with darkness. Every page of this lyrical book feels like an opportunity to ask: How did I not know about this before? For example, we learn that it can take hours, not minutes, for human eyes to reach full night vision capacity. And that there are thousands of firefly species on earth, many with flash patterns as unique as fingerprints. In an age of increasing artificial light, Night Magic focuses on the amazing biodiversity that still surrounds us after sunset. We do not need to stargaze into the distant cosmos or dive into the depths of oceans to find awe in the dark. There are dazzling wonders in our own backyards. And readers of World of Wonders, Entangled Life, and The Hidden Life of Trees will discover joy in Night Magic.

Glial Mechanisms in Sleep and Circadian Biology presents a comprehensive and up-to-date discussion of the role of glial cells in numerous, often unexpected, aspects of sleep. It seamlessly links glial cell activity to the multi-system processes that affect sleep. Experts in the field discuss how glial cells influence the sleep-wake cycle, the accumulation and discharge of sleep drive, the timing of sleep and wake across the 24-hour day, and how glial cells may govern important sleep functions (e.g., brain plasticity and metabolism). This is a book that could well change scientists’ and practitioners’ traditional beliefs about the factors underlying sleep. Users will find the book's content at the forefront of one of the hottest topics in basic sleep research. Over the last decade, scientists have made breakthrough discoveries revealing that sleep is not only a product of neurons, but of neuronal-glial interactions.
