Imaging and visualizing fossils in three dimensions with tomography is a powerful approach in paleontology. Here, the authors introduce select destructive and non-destructive tomographic techniques that are routinely applied to fossils and review how this work has improved our understanding of the anatomy, function, taphonomy, and phylogeny of fossil echinoderms. Building on this, this Element discusses how new imaging and computational methods have great promise for addressing long-standi...

The ability for people to connect, learn, and communicate about science has been enhanced through the Internet, specifically through social media platforms. Facebook and Twitter are well-studied, while Instagram is understudied. This Element provides insight into using Instagram as a science education platform by pioneering a set of calculated metrics, using a paleontology-focused account as a case study. Framed by the theory of affinity spaces, the authors conducted year-long analyses of ...

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 ...

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 ...

Roan Mountain's remarkable ecosystem has enchanted people for centuries, beginning with the first native inhabitants.Then came pioneering settlers, celebrated naturalists like John Muir, hardworking miners and loggers eager to make a living from the land and ambitious businessmen such as John T. Wilder, whose Cloudland Hotel helped make Roan a tourist destination in the late 1870s. Today, conservationists, researchers and nature lovers of all kinds flock here to experience flora and fauna ...

At the beginning of June 1961, the tensions of the Cold War were supposed to abate as both sides sought a resolution. The two most important men in the world, John F. Kennedy and Nikita Khrushchev, met for a summit in Vienna. Yet the high hopes were disappointed. Within months the Cold War had become very hot: Khrushchev built the Berlin Wall and a year later he sent missiles to Cuba to threaten the United States directly.Despite the fact that the Vienna Summit yielded barely any t...

Mothers might be exhausted, over-touched and under-appreciated, but they’re problem solvers who know how to get their “self-care” on. In If Mom’s Happy: Stories of Erotic Mothers, we hear from women waiting for their child’s arrival; mothers of infants, toddlers and teenagers; straight, queer, partnered and single mothers. We hear from mothers who like it vanilla and others who want some kink. They lust after their longtime partners and near strangers, in public and in private, al...

It's a grubby-grey, hazy-sky day.All Juniper wants is to play on the sand, but it's too wet and Mamma's busy with work. Mamma suggests she paint a picture, but what can Juniper paint?How about the beach, the way she wants it to be?

The digital revolution has greatly influenced communication, meaning a current, analytical examination of changing literacy skills is needed. Becoming literate in today’s world requires an understanding of traditional and electronic messaging venues in order for communications to not be misled by unrecognized influences.This book examines changes in the concept of literacy, including, the specific characteristics of evaluation literacy, predictors of literacy efficiency, the nature...

Die Trainer haben sich abermals etwas Besonderes für die Camp-Mitglieder ausgedacht. Jedem Spieler wird ein Kommandant zugeteilt, der diesem über Funk Anweisungen gibt. Die Konstellation könnte mal wieder nicht ungünstiger sein. Als ob das nicht schon alles anstrengend genug ist, entscheidet sich die Klatsch-Reporterin Nicolette, die Camp-Mitglieder den ganzen Tag zu begleiten und mit Interviewfragen zu löchern.

Leisure, Plantations, and the Making of New South investigates the social, architectural, and environmental history of sporting plantations in the South Carolina lowcountry and the Red Hills region of southeast Georgia and northern Florida. Although plantations figure prominently in histories of the post-emancipation South, historians have paid little attention to the redevelopment of plantations for non-agricultural use. By examining the two largest concentrations of sporting plantations ...
