Excluding the biological polymers proteins, lipids and nucleic acids, modified tetrapyrroles are the biological molecules that have had the greatest impact on the evolution of life over the past 4 billion years. They are involved in a wide variety of fundamental processes that underpin central primary metabolism in all kingdoms of life, from photosynthesis to methanogenesis. Moreover, they bring colour into the world and it is for this reason that these compounds have been appropriately dubbed the pigments of life . To understand how and why these molecules have been so universally...

He seethes with raw power the first time I see him-pure menace and rippling muscles in shackles. He's dangerous. He's wild. He's the most beautiful thing I've ever seen.

So I hide behind my prim glasses and my book like I always do, because I have secrets too. Then he shows up in the prison writing class I have to teach, and he blows me away with his honesty. He tells me secrets in his stories, and it's getting harder to hide mine. I shiver when he gets too close, with only the cuffs and the bars and the guards holding him back. At night I can't stop thinking about him in his cell....

The Convention on Biological Diversity set a world target: to achieve by 2010 a significant reduction of the current rate of biodiversity loss . The EU went further, aiming to halt biodiversity loss by 2010. In March 2010, the charity Butterfly Conservation held its 6th International Symposium on The 2010 Target and Beyond for Lepidoptera . This book, edited by John Dover, Martin Warren and Tim Shreeve and with a Forward by Sir David Attenborough, is a collection of papers from that meeting. The book documents the failure to achieve the 2010 targets and the urgent need to redouble...
