The story of seeds, in a nutshell, is a tale of evolution. From the tiny sesame that we sprinkle on our bagels to the forty-five-pound double coconut borne by the coco de mer tree, seeds are a perpetual reminder of the complexity and diversity of life on earth. With An Orchard Invisible, Jonathan Silvertown presents the oft-ignored seed with the natural history it deserves, one nearly as varied and surprising as the earth’s flora itself.
Beginning with the evolution of the first seed plant from fernlike ancestors more than 360 million years ago, Silvertown carries his tale through epochs and around the globe. In a clear and engaging style, he delves into the science of seeds: How and why do some lie dormant for years on end? How did seeds evolve? The wide variety of uses that humans have developed for seeds of all sorts also receives a fascinating look, studded with examples, including foods, oils, perfumes, and pharmaceuticals. An able guide with an eye for the unusual, Silvertown is happy to take readers on unexpected—but always interesting—tangents, from Lyme disease to human color vision to the Salem witch trials. But he never lets us forget that the driving force behind the story of seeds—its theme, even—is evolution, with its irrepressible habit of stumbling upon new solutions to the challenges of life.
"I have great faith in a seed," Thoreau wrote. "Convince me that you have a seed there, and I am prepared to expect wonders." Written with a scientist’s knowledge and a gardener’s delight, An Orchard Invisible offers those wonders in a package that will be irresistible to science buffs and green thumbs alike.

The book emphasizes the particular characteristics of plants that affect their population biology, and evolutionary questions that are particularly relevant for plants. Wherever appropriate, it is shown how ecology and genetics interact, presenting a rounded picture of the population biology of plants.
Topics covered include variation and its inheritance, genetic markers including molecular markers, plant breeding systems, ecological genetics, intraspecific interactions, population dynamics, regional dynamics and metapopulations, competition and coexistence, and the evolution of breeding systems and life history. An extensive bibliography provides access to the recent literature that will be invaluable to students and academics alike.
Effective integration of plant population ecology, population genetics and evolutionary biology. The new edition is thoroughly revised and now includes molecular techniques. The genetics chapters have been completely rewritten by a new co-author, Deborah Charlesworth.195 kr

What is humour? Why do we laugh? And why is the root of a good joke almost always error?
Good jokes, bad jokes, clever jokes, dad jokes — the desire to laugh is universal. But why do we find some gags hilarious, whilst others fall flat? Why does explaining a joke make it less amusing rather than more so? Why is laughter contagious, and why did it evolve in the first place?
Using the oldest jokes and the latest science, in The Comedy of Error, Professor Jonathan Silvertown investigates why we laugh: from laughter’s evolutionary origins, to similarities and differences in humour across cultures, and even why being funny makes us sexier.
As this unique book demonstrates, understanding how humour really works can provide endless entertainment.
