We have all heard the horror stories of invasives, from Japanese knotweed that puts fear into the heart of gardeners to brown tree snakes that have taken over the island of Guam. But do we need to fear invaders? And indeed, can we control them, and do we choose the right targets…

Where do camels belong? In the Arab world may seem the obvious answer, but they are relative newcomers there. They evolved in North America, retain their greatest diversity in South America, and the only remaining wild dromedaries are in Australia. This is a classic example of t…

In an era of climate change and widespread ecological damage, it is absolutely crucial that we find ways to help nature regenerate. Embracing the new ecology, Pearce shows us, is our best chance. To be an environmentalist in the twenty-first century means celebrating nature's wi…
A provocative exploration of the 'new ecology' and why most of what we think we know about alien species is wrong.

Over the past several decades, the field of invasion biology has rapidly expanded as global trade and the spread of human populations have increasingly carried animal and plant species across natural barriers that have kept them ecologically separated for millions of years. Beca…

We live in a globalised world in which people and goods are transported across ecosystem boundaries in greater volumes and faster than ever before. One consequence of globalisation has been the introduction, establishment, and spread of many thousands of species beyond the ecosy…
"Of the 7,000 estimated non-native species present in North America, approximately 1,000 are invasive. Clearly, invasive species are in the minority, but their small numbers don't keep them from causing billions of dollars in economic and ecological harm each year. Policymakers …
Invasive species come in all sizes, from plant pathogens like the chestnut blight in eastern North America, to the red imported fire ant that has spread throughout the South, the predatory Indian mongoose now found in the Caribbean and Hawaii, and the huge Burmese python populat…
