A Nature Guide for a Human Planet

What is Nature? Are you imagining a place without people? If you did, that’s no surprise. Even in kindergarten many are taught to think of the global patterns of nature in terms of tropical rainforests, savannas, deserts, and other “natural” patterns of ecology – the biomes shaped by climate that were first recognized by Alexander von Humboldt more than two […]

All is not loss: Plant Biodiversity in the Anthropocene

What are we humans doing to biodiversity in the Anthropocene? Causing Earth’s sixth mass extinction? (e.g. Barnosky et al. 2011 and others). How about something completely new to biodiversity on this planet? How about a massive globalization of species leading to the widespread emergence of novel ecosystems enriched with exotic and domesticated species (Hobbs et al. 2009). That’s the main […]

Globalization is good for the biosphere

Finally some good news about global change: globalization is making us cooperate! This is no minor discovery. Poverty, global warming, environmental degradation and biodiversity loss- all of these will only be solved when all of the people of all nations collaborate sustainably in doing so- though all these solutions must ultimately be local as well, because all global problems are […]

The human jungle

Are pristine rainforests the only ones that matter? We know that forests do change as they age, developing some unique characteristics when mature, and that some species cannot live outside of large swaths of ancient tropical forests. But what about the rest of tropical forests- the younger ones, the forests that people live in or have cut in recent decades […]

Remember the matrix! (no habitat is an island)

Conservation of biodiversity requires the conservation of habitat, and for a long time, this has meant preserving the largest possible “pristine” habitats and excluding humans. Now that humans have fragmented most of earth’s landscapes into mosaics that combine croplands, settlements, and remaining wilder and recovering habitats, the task of conserving or restoring large, unbroken wildlands is daunting, and often impossible. […]

Anthromes on the cover of Frontiers in Ecology

At last! After nearly one year online, my paper with Navin Ramankutty introducing Anthropogenic Biomes (Anthromes), is now in print in the October issue of Frontiers in Ecology and the Environment. Even better, it is on the cover! The paper can be viewed online (with permission) at the Frontiers in Ecology web site: esajournals.org/doi/abs/10.1890/070062 And downloaded for free, here: ecotope.org/people/ellis/papers/ellis_2008.pdf […]
