Description:

Beekeeping is more than a hobby – it’s a craft and passion shared by people from all walks of life. Beekeeping: A Practical Guide for Considerate Beekeepers blends the first-hand knowledge of experienced beekeepers, Clare Densley and Martin Hann of Buckfast Abbey, with field-tested methods to help beekeepers better understand the complex nature of honey bee society and foster a more harmonious relationship with their colonies. It delves into the complexities of swarming, unpredictable bee behaviour, and practical solutions when things go awry. Keeping bees is an opportunity for continual learning and acquiring new skills, and this book is designed to accompany beekeepers on their journey of discovery.

Description:

Species Problems and Beyond offers a collection of up-to-date essays discussing from an interdisciplinary perspective the many ramifications of the ‘Species Problem.’ The authors represent experts in the philosophy of biology, in species-level evolutionary investigations, and in biodiversity studies and conservation. Some of the topics addressed concern the context sensitivity of the term ‘species’; species as individuals, processes, natural kinds, or as ‘operative concepts’; species delimitation in the age of Big (genomic) Data; and taxonomic inflation and its consequences for conservation strategies. The carefully edited volume will be an invaluable resource for philosophers of biology and evolutionary biologists alike.
– Olivier Rieppel, Rowe Family Curator of Evolutionary Biology, Negaunee Integrative Research Center, Field Museum, USA
Species, or ‘the Species Problem’, is a topic in science, in the philosophy of science, and in general philosophy. In fact, it encompasses many aspects of the same problem, and these are dealt with in this volume. Species are often thought of as fundamental units of biological matter to be used in ecology, conservation, classification, and biodiversity. The chapters in this book present opposing views on the current philosophical and conceptual issues of the Species Problem in biology.
Divided into four sections, Concepts and Theories, Practice and Methods, Ranks and Trees and Names, and Metaphysics and Epistemologies, the book is authored by biologists, philosophers, and historians, many leaders in their fields. Topics include ontology of species, definitions of both species category and units, species rank, speciation issues, nomenclature, ecology, and species conservation.
Species Problems and Beyond aims to clarify the contemporary issues of the Species Problem. It is ideal for use in upper-level seminars and courses in Evolutionary Biology, Philosophy of Science, Philosophy of Biology, Systematics and Taxonomy, and Phylogenetics/Cladistics, and for any scholar in these fields.

Description:

Do all problems have solutions? Is complexity synonymous with difficulty? This original collection of mathematical puzzles and paradoxes proves that things aren’t always what they seem! Readers will discover that nothing is as easy or as difficult as it looks and that puzzles can have one, several, or no solutions. The fun-filled puzzles begin with The Tricky Hole, a challenge that involves pushing a large coin through a small hole in a sheet of paper without ripping or making any cuts in the paper. Advance to the Elastic Playing Card, in which it’s possible to cut a hole into a playing card big enough for someone to climb through. Other incredible puzzles include Elephants and Castles, Trianglized Kangaroo, Honest Dice and Logic Dice, Mind-reading Powers, and dozens more. Complete solutions explain the mathematical realities behind the fantastic-sounding challenges.

“Gaby Melian tells so many stories through her relationship with food-about love, about loss, about hard work, and about finding her passion. The pages are dripping with delicious smells and tastes, and will give you a new way to look at both cooking and what it means to have a plan.” -Molly Birnbaum, editor in chief, America’s Test Kitchen Kids

In this moving, personal account, chef and activist Gaby Melian shares her journey with food and how creating a relationship with food – however simple or complicated – is a form of activism in its own right.

“Food rescued me so many other times – not only because I sold food to survive. I cook to entertain; I cook to be liked; I cook to be loved.” In this installment, chef and activist Gaby Melian shares her personal journey with food – from growing up in Argentina to her time as a Jersey City street vendor and later, as Bon Appetit’s test kitchen manager. Powerful and full of heart, here, Melian explores how we can develop a relationship with food that’s healthy, sustainable, and thoughtful.

Learn how to talk like a pro when tasting wine with this fun, and funny, illustrated guide by James Beard Award–winning writer and wine professional Maryse Chevriere.
Have you ever been stumped in a restaurant, when the sommelier asks if you like a super lean Chablis or a grippy Nebbiolo? Or reading the descriptions in a wine store, hoping to figure out what a hint of red fruit and smoke on the finish of that bottle really means?

That’s where this book will save you.

How to Sound Wine Smart is a one-of-a-kind visual glossary, written and playfully illustrated by certified sommelier and James Beard Award-winning writer Maryse Chevriere. It breaks down the complicated, often ridiculous-sounding language into its component parts. You’ll learn terms to describe what’s going on in a glass of wine, from its first impressions, aroma, flavor, acidity, texture and mouthfeel, condition, personality, to its faults and flaws-including sentences to impress people in real life. Even in a wine store!

And that’s not all. Throughout the book are informative sections that explore crucial aspects of the world of wine like unfiltered vs. filtered, old world vs. new world, and more. There’s also a guide to glassware. Cheat sheets for tackling wine pairings, too. To put your knowledge to the test, Maryse has designed drinking games that will have you smelling and tasting wines side-by-side to understand the quality of dry and sweet German Rieslings. Or the flavor differences between chardonnays that were aged in stainless steel or new oak. She makes this topic less intimidating, more accessible, and, always, enjoyable.

Whether you’re a longtime wine lover or a curious beginner, How to Sound Wine Smart is a necessary (and fun, and funny) reference. No other book provides a deep dive on the lexicon of wine lingo. Learn what to say, and how to say it. Learn how to sound wine smart. And savor every sip along the way.

This book, written by a distinguished scientist in the field, provides a comprehensive overview of the biochemical aspects of all luminous organisms currently known. It is the first and only book that provides chemical information on all known bioluminescence systems, in a single volume. Some 35 different types of bioluminescence organisms are discussed in 10 chapters. The descriptions include: a history of the discovery of luminescence substances such as luciferins, luciferases and photoproteins; the process of research, explaining how luminescent substances have been isolated and purified; the properties of luminescent substances; and the reaction modes and mechanisms involved, as interpreted currently. Important experimental data and graphs are included in the book, making time-consuming reference searches almost unnecessary. Helpful advice for experimentalists is given in an appendix.
