Imagine taking your smartphone-turned-microscope to an empty lot and discovering a rare mason bee that builds its nest in empty snail shells. Or a miniature spider that hunts ants and carries their corpses around. With a team of citizen scientists, that's exactly what Menno Schilthuizen did--one instance in the evolutionary biologist's campaign to take natural science to the urban landscape where most of us live today. In this delightful book, The Urban Naturalist, Schilthuizen invites us to join him, to embark on a new age of discovery, venturing out as intrepid explorers of our own urban habitat--and maybe in the process do the natural world some good.

Thanks to the open science revolution, real biological discoveries can now be made by anyone right where they live. Schilthuizen shows readers just how to go about making those discoveries, introducing them to the tools of the trade of the urban community scientist, from the tried and tested (the field notebook, the butterfly net, and the hand lens) to the newfangled (internet resources, low-tech gadgets, and off-the-shelf gizmos). But beyond technology, his book holds the promise of reviving the lost tradition of the citizen scientist--rekindling the spirit of the Victorian naturalist for the modern world.

At a time when the only nature most people get to see is urban, The Urban Naturalist demonstrates that understanding the novel ecosystems around us is our best hope for appreciating and protecting biodiversity.

From evolutionary biologist Menno Schilthuizen, a book that will make you see yourself and the world around you in an entirely new way

*Carrion crows in the Japanese city of Sendai have learned to use passing traffic to crack nuts.

*Lizards in Puerto Rico are evolving feet that better grip surfaces like concrete.

*Europe's urban blackbirds sing at a higher pitch than their rural cousins, to be heard over the din of traffic.

How is this happening?

Menno Schilthuizen is one of a growing number of urban ecologists studying how our manmade environments are accelerating and changing the evolution of the animals and plants around us. In Darwin Comes to Town, he takes us around the world for an up-close look at just how stunningly flexible and swift-moving natural selection can be.

With human populations growing, we're having an increasing impact on global ecosystems, and nowhere do these impacts overlap as much as they do in cities. The urban environment is about as extreme as it gets, and the wild animals and plants that live side-by-side with us need to adapt to a whole suite of challenging conditions: they must manage in the city's hotter climate (the urban heat island); they need to be able to live either in the semidesert of the tall, rocky, and cavernous structures we call buildings or in the pocket-like oases of city parks (which pose their own dangers, including smog and free-rangingdogs and cats); traffic causes continuous noise, a mist of fine dust particles, and barriers to movement for any animal that cannot fly or burrow; food sources are mainly human-derived. And yet, as Schilthuizen shows, the wildlife sharing these spaces with us is not just surviving, but evolving ways of thriving.

Darwin Comes toTown 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. It reveals that evolution can happen far more rapidly than Darwin dreamed, while providing a glimmer of hope that our race toward over population might not take the rest of nature down with us.

In an age of increasing environmental problems, ecology has had to grow up fast from a discipline dealing with relatively simple interactions between species to one that tries to explain changes in global patterns of diversity and richness. The issues are complex. Every species may seem to have its own unique role, but if that is true, then why are there hundreds of species of plankton in an ecosystem with only a handful of niches? The tropics have a high biodiversity, but does anybody know why? And how can a single introduced tree species wreak havoc in Hawaii's rainforests, when it is one of thousands of quietly coexisting tree species in its native continent, South America?
The strength of this book is that it will help digest some of these more complex issues in the ecology of biodiversity. It will do this by zooming out from the local scale to the global scale in a number of steps, marrying community ecology with macroecology, and introducing unexpected nuggets of natural history along the way. The reader will notice that, the larger the scale, the more the familiar niche-concept appears to be overshadowed by exotic fields from fractal and complexity theory. However, scientists differ in opinion on the scale at which niches become irrelevant. These differences of opinion, but also the search for unified ecological theories, will form another force by which the story will be carried along to its conclusion. A conclusion which, surprisingly, seeks to find a glimpse of the globe's future in the traces from its past.
