Capire l'oggi per creare il domani. Un percorso di trasformazione su tre livelli: spirituale, culturale e tecnico. L'Uomo si è ormai perso nella sua rincorsa feroce al progresso, tutti gli ambiti delle sue attività danno continui messaggi d'allarme. L'ecosistema terrestre e la vita dell'Uomo stesso non sono mai stati messi a rischio come in questi ultimi decenni di enorme sviluppo industriale ed economico.

Life histories can be defined as the means by which individuals (or more precisely genotypes) vary their age- or stage-specific expenditures of reproductive effort in response to genetic, phenotypic, and environmental correlates of survival and fecundity. Life histories reflect the expression of traits most closely related to individual fitness, such as age and size at maturity, number and size of offspring, and the timing of the expression of those traits throughout an individual's life. Life-history research plays an integral role in species conservation and management. 

When did the human species turn against the planet that we depend on for survival? Human industry and consumption of resources have altered the climate, polluted the water and soil, destroyed ecosystems, and rendered many species extinct, vastly increasing the likelihood of an ecological catastrophe. How did humankind come to rule nature to such an extent? To regard the planet's resources and creatures as ours for the taking? To find ourselves on a seemingly relentless path toward ecocide?

An entertaining and enlightening exploration of why waste matters, this cultural history explores an often ignored subject matter and makes a compelling argument for a deeper understanding of human and animal waste. Approaching the subject from a variety of perspectives - evolutionary, ecological, and cultural - this examination shows how integral excrement is to biodiversity, agriculture, public health, food production and distribution, and global ecosystems.

A beekeeper herself, she gives insight into the activity in the hive and describes the bees' natural order and habits. She explores the myths of the past and how and when they were replaced by fact. For example, the heated discussions that broke out in the 18th century when it was discovered that the hive was ruled by a queen, not a king as had been the belief since Aristotle. 

Darwin Comes to Town draws on eye-popping examples of adaptation to share a stunning vision of urban evolution in which humans and wildlife co-exist in a unique harmony. *Carrion crows in the Japanese city of Sendai have learned to use passing traffic to crack nuts. *Lizards in Puerto Rico are...

This book explores a new approach to understanding the evolution of mind and consciousness by examining the perceptual abilities of animals and the way they experience their world. It offers a science-based, bottom-up approach to our own conscious worldview by seeing it through the eyes of...

Brilliant offers a sweeping view of a surprisingly revealing aspect of human history - from the stone lamps of the Pleistocene to the LEDs embedded in fabrics of the future. Jane Brox plumbs the class implications of light - who had it, who didn't - through the many centuries when crude lamps and tallow candles constricted waking hours. Brillant is infused with human voices, startling insights, and - only a few years before it becomes illegal to sell most incandescent light bulbs in the United States - timely questions about how our future lives will be shaped by light.

In humanity’s more than 100,000 year history, we have evolved from vulnerable creatures clawing sustenance from Earth to a sophisticated global society manipulating every inch of it. In short, we have become the dominant animal. Why, then, are we creating a world that threatens our own species? What can we do to change the current trajectory toward more climate change, increased famine, and epidemic disease?

In this fresh and provocative view of a seven-million-year evolutionary journey, Finlayson demonstrates the radical implications for the interpretation of fossils and technologies and shows that understanding humans within an ecological context provides insights into the emergence and spread of Homo sapiens worldwide.

Vivants ou fossiles, les oursins sont des animaux étranges à nos yeux. Sans queue ni tête, ils sont une clé pour comprendre les mystères de l'évolution. Chercheur acharné, Bruno David a poussé l'enquête sur les échinodermes des plaines du Bassin parisien jusque dans les abysses, en s'aidant des outils les plus inattendus. On découvre ainsi, entre autres, que les oursins n'ont pas toujours un aspect de petites boules piquantes, qu'il existe des oursins kangourous, ou encore qu'il arrive aux crabes de maltraiter les oursins.
