Before global warming, even before the human population exploded to 7.3 billion, scientists, philosophers and lovers of nature were already concerned with the conservation of plants, insects, fish, amphibians, birds and mammals, both in terrestrial and marine settings, and in ecosystems as diverse as tropical forests through to the Antarctic. As a conservation ecologist, therefore, I am carrying on a long tradition of studying ecosystems and trying to understand the complex interactions between the diverse plants and animals that inhabit them, and what happens when ecosystems begin to unravel as habitats and their inhabitants are lost due to the effects of human activity. Where I diverge from tradition is by examining the increasingly complex interactions between human behaviour, infrastructure, energy, agriculture and the environment.

To appreciate the impact of deforestation, pollution, habitat loss, extinctions, over-grazing, over-fishing or warming seas, I analyse information about different ecosystems worldwide to estimate the impact of human activity. I specialise in applying mathematical models to large multi-species datasets to determine global-scale patterns of threat to biodiversity. The research involves the use of cross-disciplinary (standard sampling of species abundance, genetics, physiology, behaviour, economics, policy) data and methods; the results are quantitative, sound and defendable. In a world where human activity has precipitated the current ‘Anthropocene’ extinction event and the subsequent loss of hundreds of thousands of species, my aim is to provide evidence that is irrefutable to influence government policy and private behaviour.

Only with rational data can human attitudes and behaviours be shifted away from the wholesale modification of the biosphere and towards the conservation of the ecosystem services that support life, such as pure water and clean air, along with habitat and species diversity.

Hello Prof Bradshaw,
As an Environmental student (mature age) I’m in awe of all your accomplishments and knowledge, where? how? I wish. It seems you walk around and make a mental list of things you must find out about one day.Anyhow for the rest of us there is your blogspot fantastic work very admirable.

Thank you for the kind words. In summary, I’m a very busy person!

Abbs said she caught up with you yesterday and recommended I have a look at your blog and steal all your ideas. Impressive mate, too much for me to contemplate thieving in one go.

How the hell are you and when can we all catch up and drink heavily?

PS Antarctica was awesome (again!)!

HI CJAB, Thank you for your kind response. Would you be willing to let the world know about the plight of the monarch butterfly? As a species in Canada, USA and Mexico the butterfly is at risk from a collapsing natural world often caused by man’s indifference. Then along comes drought and the pine beetle in the Mexican monarch butterfly sancutary which further complicates the butterfly’s existance.

You can read our information on our blogs at http://www.insectamonarca.wordpress.com, http://www.happytonics.wordpress.com and from our Web site at http://www.happytonics.org

Thank you for explaining about the interdependance of all species.
What we do to the butterfly, we do to ourselves. I am looking forward to your future articles on biodiversity and sustainability in the midst of a collapsing natural world. It takes people like you to make the world see that we are all related.

Best wishes,
Mary Ellen

hey, just read your thing on Sharks its great

i’m in a metal band and this month we are to release our new Cd “sharks”

Josh – no problem, but you’ll have to ask the photographer directly, Rob Harcourt. I’ll send his email.

Hi There!
I thought you might like to know about a global action campaign I have started to free bears from horrible crush cages on bile farms. Most people don’t even know these places of hell exist for bears. Having you include our action campaign on your blogsite could help generate more awareness and direct action to end bile farming and free the the 9,000 bears that are locked in crush cages so small they can’t even move.

Here are some sites that can provide more information:

Thanks, and I”ll be looking for you!
